TI : Experts Laud Call For Revamping U.S. Science Education
Programs
Report warns of inadequate oversight and ineffective
planning and management of the growing number of federal
initiatives
AU : BARTON REPPERT
TY : NEWS
PG : 1
Science education specialists are endorsing a recently released
report by a top-level advisory panel warning that, despite
unprecedented government spending on science, mathematics,
engineering, and technology (SMET) education, the United
States "remains at risk of losing its competitive edge." The
experts join the report's call for significantly revamped
planning, coordination, and evaluation of the federal
government's programs in these areas.
In compiling The Federal Investment in Science, Mathematics,
Engineering, and Technology Education: Where Now? What Next?
the 15-member panel, convened by the Federal Coordinating
Council for Science, Engineering, and Technology (FCCSET),
surveyed some 300 education programs sponsored by 13 federal
departments and agencies. The initiatives the panel examined
were identified as "core programs," or those relating
directly to SMET education, and funded at a total cost of
about $2.2 billion. Support for programs not targeted
specifically to SMET education may be as much as $24
billion, the panel estimates.
In the report to FCCSET--an interagency group now being
superseded by a newly formed Cabinet- level National Science
and Technology Council--the group concludes that this
"potpourri of programs" has evolved "with too little overall
planning and with inadequate evaluation.... The federal
portfolio of core programs is unbalanced and lacks
coherence."
The panel contends that "it is time for a new culture of
interaction, communication, and coordination to be developed
and sustained within and among all federal agencies in the
area of education."
Shirley Malcom, head of the American Association for the
Advancement of Science directorate for education and human
resources, says she supports both the focus and the
direction of the report's findings and recommendations: "I
think the points that they make are absolutely on target.
Their concerns about coordination and communication and
collaboration . . . are absolutely the right ones. We have
to be a lot more willing to look at ourselves and look at
our programs in a very honest and forthright way."
Malcom, who did not serve on the FCCSET panel, adds that
"we're not going to see a lot more money in the near term .
the resources that are available."
Among the major conclusions and suggestions of the panel
are:
* The core programs are "unbalanced and lack coherence" and
require a "stronger management plan" that ensures that more
SMET programs are aligned with national strategic plan
goals; are coordinated across agencies; and promote equity.
* Current evaluations of these programs are "often
inadequate" for improving programs, providing
accountability, or deciding which ones to cut or retain.
Programs should be "evaluated rigorously," with an eye
toward meeting identified national needs.
* "Research should be directed toward what works best in
particular educational settings, for particular diverse
audiences, and in non-traditional settings such as adult
education."
* More money should be allocated to promote awareness among
teachers, students, and researchers of available federal
programs in SMET education.
* A greater emphasis should be placed on teacher-preparation
programs at all levels, including "the latest findings on
how best to promote student learning."
At the news conference to release the study early last
month, panel cochairman Karl S. Pister, chancellor of the
University of California, Santa Cruz, noted that 10 years
ago a U.S. Department of Education commission report, A
Nation at Risk, was widely acclaimed and "jarred the
national conscience."
"Unfortunately, much of what was called for in that 1983
report remains unfinished," he said. "At the same time, the
federal government's efforts in science, mathematics,
engineering, and technology education are not sufficiently
coordinated to reverse the tide of mediocrity and apathy."
Pister said the FCCSET panel's study marked the first time
that the federal programs have been "examined as a whole in
the light of independent scrutiny."
Of the current climate for action on such issues, Pister
said: "I think it's too early to judge the current
administration. But I see very positive signs." He added
that formation of the new NSTC, to be chaired personally by
President Bill Clinton, "is a telling symbol to me that the
administration is taking science and technology education
seriously."
Panel cochairwoman Mary Budd Rowe, a professor of science
education at Stanford University, told reporters that the
study found only about 20 percent of the 300 federally
supported education programs have been evaluated for their
effectiveness. "We're in a competitive, almost life-death
kind of struggle with other countries. And I don't think we
can afford to invest big amounts in programs that don't
work," she said.
Inducing Cooperation
Panel member Ernest R. House, a professor of education at
the University of Colorado, Boulder, says that even after
working in the field of government educational policy for 20
years, when he got a more detailed look at the various
programs he found the overall situation "so bad that I was
just appalled."
House says a key problem has been that interagency groups,
such as FCCSET, up to now have lacked sufficient authority
to effectively oversee the range of programs. Within the
different departments and agencies, "bureaucrats are used to
hunkering down. They've seen these things come and go many
times, so they're used to just saying, `Well, we can sit
this out.' ... So I think it will take some kind of pretty
strong authority to induce them to cooperate with each
other."
Such authority may be wielded by the newly created NSTC. The
council, established under an executive order signed last
November to coordinate science, space, and technology
policies throughout the executive branch, will incorporate
FCCSET's duties. According to an official at the White House
Office of Science and Technology Policy, FCCSET is expected
to officially go out of business this month when its
activities are taken over by NSTC and eight R&D coordinating
committees being formed under the council.
Earl Dowell, dean of the engineering school at Duke
University in Durham, N.C., says he strongly supports the
FCCSET panel's recommendation that more attention be paid to
widely disseminating information about federal programs--
particularly the results of pilot or experimental efforts.
"I think there's a lot of independent experimentation, and
that's probably good to a certain degree--but not if,
indeed, we keep repeating the same experiment without being
aware of what other people have tried," he says.
Dowell observes that "at the moment, I'm afraid that in
too many cases the educational experiments--even when well
done--tend to impact a single campus, or perhaps just a few
campuses, and not the broader range of institutions."
As an example of an NSF-supported pilot program whose
results deserve to be more widely disseminated, Dowell
points to a program involving faculty-led "engineering
education coalitions" designed to improve educational
quality at various engineering schools. Each coalition
generally involves seven or eight campuses.
`Selling' The Product
Echoing Dowell's sentiments, another member of the FCCSET
panel, Wendell G. Mohling, former president of the 50,000-
member National Science Teachers Association, says the study
shows that improved efforts are needed to provide useful
information to schools, teachers, and students about various
federally supported programs.
"Just as with anything else, if you've got a good product
you still need to sell it," he says. "For any classroom
teacher there are dozens of things that come through the
mailbox or to the school. But to get it to the teacher, at
the classroom level, is what is really the name of the game
here--to publicize these programs."
Leonard Minsky, executive director of the National Coalition
for Universities in the Public Interest, a Washington, D.C.-
based group, comments about the report: "Basically, I
couldn't agree more with the conclusions.... They're
absolutely right about the lack of coordination, evaluation,
and accountability."
He adds that "from our perspective, there's tremendous
overlap, enormous sloppiness in the system.... And
there's absolutely no way of getting any kind of
accountability out of the system as it's now constructed."
At the news conference, Luther Williams, National Science
Foundation assistant director for education and human
resources and acting chairman of FCCSET's education
committee, said he takes the report's findings "very
seriously."
"We will take this valuable input to heart, and very
carefully consider how best to respond," Williams said. "We
know we need to make some changes, and here is some sound
advice on how to start."
For the 1994 fiscal year, which began last October, NSF is
slated to spend $569 million on science and engineering
education programs--an increase of 17 percent from the year
before.
Within NSF, further steps to more thoroughly evaluate
educational programs and initiatives are expected to be
mapped out by the foundation's office of research,
evaluation, and dissemination, headed by Daryl E. Chubin,
who recently moved to NSF from the congressional Office of
Technology Assessment (P. Beck, The Scientist, Nov. 1, 1993,
page 22).

TI : WHAT THE FCCSET PANEL FOUND
TY : NEWS
PG : 10
Following are excerpts from the Federal Coordinating Council
for Science, Engineering, and Technology expert panel's
report on federal programs to support science, mathematics,
engineering, and technology (SMET) education:
* "The impact of current federal dollars in SMET education
remains unclear. A potpourri of programs has evolved.
Federal expenditures are being made with too little overall
planning and inadequate evaluation."
* "Too many Americans know virtually nothing of the
mathematical and scientific concepts and discourse (to say
nothing of the technologies) that enrich contemporary
culture, social experience, and economic progress."
* "It is the strong view of this panel ... that a basic
change in the way in which federal agencies view their roles
is needed. It is time for a new culture of interaction,
communication, and coordination to be developed and
sustained within and among all the agencies in the area of
education."
* "The panel found that today's federal programs in SMET
education continue to be burdened by a lack of coordination,
a lack of evaluation, and a lack of accountability. The
federal portfolio of investments in SMET education needs a
comprehensive, coordinated management plan to provide
balance and coherence across and within federal agencies,
other levels of government, and all levels of SMET
education."
* "Despite continued federal expenditure, the percentage of
minority students studying SMET subjects (particularly at
the graduate level) remains abysmally low. In engineering,
the physical sciences, and mathematics, women are also
significantly underrepresented .... Federally funded
programs must actively and continually seek ways to improve
participation and retention of underrepresented populations
and to make SMET accessible to all citizens."
* "For a majority of federally funded SMET education
programs, no evaluation information is available at all ...
or no serious inquiry beyond anecdotal or self-reported data
has been made. This disturbing lapse must be addressed
immediately. The federal government cannot continue to spend
large sums of money without knowing if its programs are
accomplishing their established goals."

TI : Women Scientists' Group Launches Effort To Probe The
Plight Of Female Researchers
Through campus `site visits,' AWIS will investigate the
prevalence of gender bias in academia
AU : BARBARA SPECTOR
TY : NEWS
PG : 1
The Association for Women in Science (AWIS) is planning an
ambitious project to assess the climate for female
researchers in academia--by visiting several United States
colleges and universities and talking with the women
themselves.
The effort will take AWIS representatives into several
schools for "site visits," during which they will discuss
women's concerns with faculty, administrators, and students,
reporting their findings to school officials. AWIS will also
collect samples of institutional policy statements and other
documents that women scientists feel either help or deter
their advancement, which will be evaluated for inclusion in
an upcoming publication.
The Washington, D.C.-based organization will ultimately
"develop a model program that offers workable options for
enhancing the academic climate for women science faculty"
for dissemination to schools that were not visited,
according to a draft proposal for the project.
Through this program, AWIS is trying to grapple with the
question of why "women don't seem to move up in academia as
readily as men," says AWIS past president Ellen Weaver, a
retired professor of plant physiology from San Jose State
University. "Women are hired in good faith, but somewhere on
the climb to tenure, they don't make it." A 1991 National
Research Council study Women in Science and Engineering:
Increasing Their Numbers in the 1990s, Washington, D.C.,
National Academy Press), for example, found that 66 percent
of the women Ph.D.'s on science and engineering faculties
either were not tenured or were not tenure-track, compared
with 40 percent of their male counterparts.
"The time has come to not just collect more data about how
poorly women do," says Weaver, a co-principal investigator
(PI) on the project. "It's time to go in and find out what's
happening.
"We've been concentrating on teaching the women what they need to
know to succeed, but maybe there's something the institution can
do to be more accommodating to women."
The AWIS effort is modeled on a program now being conducted under
the sponsorship of the American Physical Society (APS) and the
American Association of Physics Teachers (AAPT), both of College
Park, Md., and funded by the National Science Foundation. In the
physics project, groups of women physicists conduct day-long site
visits to departments that have requested help in improving the
climate for women. AWIS aims to expand the effort, spending a
longer time at each institution and looking at all its science
departments.
AWIS is currently soliciting funding for its project and expects
to clarify the funding status in March; in the meantime, it has
begun collecting policy documents from various schools on an ad
hoc basis.
In the project's initial phase, expected to take a year and a
half, the organization will visit one institution--probably a
liberal arts college, according to Weaver--and make
recommendations for changes. In the second phase, AWIS will
expand its visits to six schools, including a major research
university and a historically black institution, "looking for
institutional differences as well as departmental differences,"
says AWIS executive director Catherine Didion, a co-PI on the
project. The program's final phase involves the creation of
"regional training centers," where academics will attend
seminars, receive diversity training, and learn how to adapt such
programs for their own schools. Materials and methods used in
these centers will be developed from information gathered in the
site visits.
Key to the success of the project--and a crucial component of the
physics program after which it is modeled--is that site-visit
teams go only to institutions that invite them, and where high-
level administrators communicate the importance of the visit to
the faculty, AWIS officials say. "There has to be a commitment in
order to get anywhere on these issues," says Didion. "This
program only works if you have support from the top."
Didion acknowledges that the idea of a site visit may be daunting
to some administrators--"none of us would want someone to come in
and tell us, `This is what you could be doing better'"--but notes
that the goal is to reach "the institutions that recognize that
they want to change and that they need to change." And, indeed,
there are male administrators at such schools who will welcome
the visitors, Didion says. "Men know they have to be part of the
solution" to the problem of an unfriendly climate for women, she
says, "but they don't know how to go about it. There's not a
recognition of what the barriers are and how to address them."
A Model Program
The experience of the women physicists, who have been conducting
site visits since 1990, bears this out. In fact, says Judy Franz,
a professor of physics at the University of Alabama, Huntsville,
and a co-PI on the physics site-visit project, the effort was
born out of a meeting of physics department heads--an
overwhelmingly male group. "They passed a resolution that more
should be done by them to encourage women and minorities to enter
physics, and wanted help from APS and AAPT," she recalls.
"We can get as many invitations as we need" to conduct site
visits, says Mildred Dresselhaus, Institute Professor of
Electrical Engineering and Physics at the Massachusetts Institute
of Technology and co-PI along with Franz. "Fifteen years ago,
there were a lot of individuals who would consider [climate
issues for women] a non-problem. Now they are in the minority."
While the site-visit reports are addressed to a department
chairman, the team tries to meet with the provost, the president,
and other senior administrators when possible; chairmen may share
the team's report with faculty, students, and administrators.
Only 3 percent of physics faculty in U.S. universities are women,
according to APS's Committee on the Status of Women in Physics.
At the undergraduate and graduate levels, women physics students
are a small minority, as well. As a result, some problems women
physics students face are less common in disciplines such as
biology, in which the numbers of women are greater, says Bunny
Clark, University Professor of physics at Ohio State University
and a site-visit team member.
Clark says that male physicists' lack of experience with dealing
with women professionally may contribute to what could be viewed
as a sexist environment. "In some cases, [male physicists']
socialization is perhaps slower than it would be in a situation
in which there were equal numbers of men and women," she says.
"What we've found is less than we would hope for in the ideal
world," says Dresselhaus.
Site-Visit Findings
One issue that has come up during site visits, for example, is
the presence of posters in the lab or office depicting nude
or semi-clad women, say site-visit team members. "Some
people who have them up don't even realize that people would find
them offensive," says Franz.
Another site-visit finding is that male teaching assistants (TAs)
often "are not given any training" on how to behave at the front
of a classroom, says Michelle Shinn, an associate professor of
physics at Bryn Mawr College who has been on several site visits.
"How they're going to treat their women students is just left to
their upbringing." As a result, she says, often "women feel
undervalued or patronized--as a woman, you become the recorder of
data rather than the taker of data, or a male TA might say
something demeaning or flirt with you."
In a department with few women, a sense of isolation can
exacerbate cases such as these, women physicists say, leading to
a tendency to take personally issues that others might consider
trivial. "When a woman often never sees another woman during the
day, they think it's them, not the situation," says Dresselhaus.
To help overcome such problems--or, at least, to bring them to
the attention of an official who can do something about them--
site-visit teams have frequently recommended that a department
chairman schedule regular meetings with women students. Several
departments that have undergone site visits have implemented this
suggestion already.
"They encouraged us to try to [establish] a smaller-depart- ment
kind of feeling," says David Campbell, physics department head at
the University of Illinois, Urbana-Champaign. Campbell, who
administers nearly 300 graduate students and 66 faculty members,
says that as a result of the November 1992 site visit, his
department instituted a faculty-student mentoring program and
revived a peer mentoring program that "had sort of
sputtered."
In addition, says Campbell, after he received the site-visit
report, he met with women students to discuss the findings,
including the need "to make the department a slightly warmer
place" and the high degree of stress caused by the physics
qualifying exam. "Eighty-six percent of the students who take it
twice pass it, but there is a rumor that half the students fail,"
says Campbell. "We're working on trying to debunk that."
The physicists emphasize that a number of the site-visit teams'
suggestions, if implemented, should help men as well as women.
"One thing we really learned is that many of these problems are
not gender-specific," says Campbell.
While the chairmen may enthusiastically welcome the site
visitors, not every faculty member agrees that such an exercise
is a good idea. "There are some individuals at these departments
who would rather see us disappear off the face of the Earth--and
we hear about it," says Dresselhaus.
James Legg, physics chairman at Kansas State University, whose
department was visited this past fall, said that the reaction of
the 25 faculty members covered a "wide range of responses--`Why
are you doing this?' being one of them--[ranging to] `Good; I'm
glad that we're looking at this issue and taking it seriously.'"
The "defense mechanisms" manifested by the faculty who reacted
negatively to the visit, Legg says, included questions such as
"`Why, in a time of tight employment, are you concentrating on
women?'" and "`Is it really true that women are being
disadvantaged by the atmosphere that we have today?'"
Toh-Ming Lu, physics chairman at Rensselaer Polytechnic
Institute, says he wanted to have his spring 1992 site visit "not
because we have something really good to show, but to see how
they can help us improve.
"We recognize that this is a key issue and should be dealt with,"
he says. "We also recognize that we are historically male-
dominated. We [didn't] expect a glowing report." His goals for
the encounter, he says, were "to stimulate some discussion, to
encourage us to talk about what other women scientists think
about--bad or good; to let our students meet with other women
physicists, which we always want to do; and to let our
administration know about women's issues.
"Because we have been male-dominated for such a long time, we
lost track of realistic women's science issues," he says. In such
circumstances, "you don't have in your mind how the real world
is, how difficult it is for women to study physics."
Creating Change
Didion says her organization decided to adopt the physics program
because "we thought it meshed well with AWIS. Our strength is in
trying to do intervention--to create change as a catalyst."
Evaluations from those outside an institution can be advantageous
in this respect, she says: "Sometimes external organizations can
do it effectively, where internal organizations won't be heard."
The goal of the AWIS project is not to solve individual women's
problems, Weaver emphasizes: "We're looking at factors," she
says. "We're not going to pursue anyone's individual case."
One reason the physics program has been able to garner
invitations from so many schools, site-visit team members and
department members say, is that the teams are composed of senior,
respected scientists; Dresselhaus, for example, is a member of
the National Academy of Sciences. "When I put together a team, I
try to get people from different areas of physics," says Franz.
Usually, some faculty members [at the school being visited] would
recognize at least one of our names."
Kansas State's Legg says that, for him, the benefits of the visit
were obvious. "Is it better to remain ignorant about the problems
that you may have?" he asks rhetorically. "To me, it's a win-win
situation. If they come in and point out problems and give us
ways to improve them, we've got ourselves a better department.
One doesn't mind being criticized if you're going to profit from
it."

TI : Scholarship Criterion Challenged; Critics Charge Sex
Discrimination
AU : FRANKLIN HOKE
TY : NEWS
PG : 1
Charges of sexual bias in a $2.2 million federally funded
undergraduate scholarship program have kindled debate among
science educators and others about the use--and misuse--of
standardized tests in gauging the abilities of future scientists.
The scholarships were awarded solely on the basis of such a test.
According to a report by the National Center for Fair and Open
Testing (FairTest) in Cambridge, Mass., male high school students
won 75 percent of the 471 college scholarships awarded in 1993,
the first year of the National Academy for Science, Space, and
Technology (NASST) program in the United States Department of
Education. This was so even though young women earn higher grades
in science and math than young men in both high school and
college, FairTest says.
The reason more men than women won, FairTest says, is that
the award relied on scores earned on the math portion of the
American College Testing (ACT) assessment exam, a test the
organization says is biased against women. The exclusive use
of a standardized test for awarding the scholarships--one
for each congressional district--was mandated by the
legislation creating NASST. NASST was established to support
students who choose science and math majors in college;
winners commit either to attend graduate school or to go to
work in a related field, one year for each year of
scholarship support.
"The real shame of this program," says Cinthia H. Schuman,
executive director of FairTest, "is that, at a time when we
should be encouraging young women to go into math and
science, we're sending the wrong message that test scores
are valued more than the actual demonstration of promise in
these areas."
Defenders of the ACT and other standardized tests
acknowledge that there is a difference between the scores of
male and female students. They insist, however, that the
bias revealed is not an indictment of the tests, but instead
is an accurate reflection of discrimination in classrooms
and in society.
"According to the National Science Foundation, 76 percent of
our college graduates in engineering; mathematics; and
physical, life, and computer science are males and 24
percent are females," said Thomas Saterfiel, vice president
of the research division at ACT, in a statement. "These
percentages are just what we see in the awarding of the new
NASST scholarships."
"There's bias," adds Kelley Hayden, a spokesman for ACT.
"There's no doubt about it. But the bias is in the
classroom--it's in the society, really. You still have
reports about how teachers call on boys more than girls in
classes, for example. So, it's just an extension of that."
Hayden also says the tests are designed to predict how
students will perform in their freshman-year college
courses. As such, he says, the ACT has a predictive validity
of 95 percent for both males and females. The tests were
never intended to be used as the sole criterion for such
scholarship awards, he adds.
"Our test scores should not be used alone to make high-
stakes decisions," Hayden says. "They should be used in
conjunction with other information, such as class grades,
recommendations, and other work that the students do."
Most critics agree on this point, but some go further,
saying that standardized tests simply are not a valid way to
predict how students will perform in science careers.
"This test is a flawed indicator," Schuman says. "Not only
is it biased against girls, it also does not reflect the
kind of skills that we are looking for in students. It
doesn't measure a student's ability to write or think
creatively or do a science experiment."
FairTest has written to members of Congress who serve on the
education committees, asking that the law be rewritten
before any further funds are appropriated for NASST.
Meanwhile, the Clinton administration, while praising the
aim of encouraging students to pursue science and math
careers, has moved to neutralize the program. Officials are
supporting instead another effort with similar goals called
the National Science Scholars program, authorized in 1990.
Under that program, which provides for broader selection
criteria, 861 students showing promise in science fields won
undergraduate scholarships this year.
"Congress stipulated in the law [that created NASST] that
the department select one scholar per congressional district
based on national test scores," said David A. Longanecker,
assistant secretary for postsecondary education, in a
statement. "The department implemented the law as authorized
by Congress. The National Science Scholars program, in
existence for several years, requires at least one female
winner per congressional district. For this reason, the
Clinton administration supports the National Science
Scholars program and has not requested any further funding
for NASST."
Without funding for the current fiscal year, the NASST
program has effectively ended, according to Stephanie
Babyak, an Education Department spokeswoman. Even without
the bias charges against NASST, she says, the programs are
largely duplicative in purpose.
Locating The Bias
Critics of standardized tests say they are inherently biased
against women, at least partly because they reward
characteristics thought to be shared by more men than women.
"Nobody has ever come up with one single cause for the
gender gap," says Schuman. "Rather, a number of issues have
been pointed to, primarily dealing with the format of the
test. Somehow, the emphasis on speed and guessing does not
allow girls to display their real abilities."
In 1989, the Center for Women Policy Studies in Washington,
D.C., published The SAT Gender Gap by Phyllis Rosser, a
study that sought to document inequities in the SAT,
administered by the New York-based College Board. According
to Leslie R. Wolfe, executive director of the center, Rosser
did an item analysis of one of the SAT tests and found that
there were 24 questions on which either men or women did
substantially better. Of those, 22 favored men, she says.
Rosser's study also directly contradicts test-makers' claims
that the exams predict the success students will have in
college, according to Wolfe.
"The only purpose [of the SAT and the ACT] is to predict
first-year college grades," Wolfe says. "In both cases, they
fail to do so for women. The SAT underpredicts women's
first-year college grades. So, you have women who earn
higher grades in their first year of college than their SAT
scores would indicate."
She adds: "High school grades are still the best predictor
of college success."
Test-makers counter that they have worked hard to eliminate
bias and have been largely successful--although some
residual inequity does remain. They say that the tests are
based on the courses students take and mirror students'
participation and success in those courses.
"The test is a curriculum-based test," says Hayden at ACT.
"If you've had, for instance, algebra, you'll score in a
certain range. But if you've had trigonometry, you'll score
higher. And if you've had calculus, you'll score higher."
About 5 percent more boys than girls take those courses,
Hayden says, and in a heavily math-based science like
physics, for example, about 11 percent more boys enroll.
Hayden also makes the point that criticizing the ACT for
rewarding speed and guessing cuts both ways.
"The English portion of the test requires you to move just
as quickly as the math portion does, and it's all multiple
choice, too," Hayden says. "But the girls do a lot better
than the boys on that. Why? Because they know that stuff
better."
Critics are unmollified by such arguments from test-makers.
"They have responded by blaming the victims and blaming the
schools for low SAT scores on the part of women," says
Wolfe. "However, we have shown that even those women with
the highest grades, sitting in the same high-level math
classes in high school with boys, and getting higher grades
[than the boys], are still getting lower SAT scores."
"The problem with tests like the ACT and the SAT," says
Schuman, "is that, even when you match for a student's
socioeconomic background, their parents' educations, the
courses taken, and the grades received, the gap between the
sexes does not entirely close."
Some science educators are more willing to give credence to
the test-makers' view.
"The testing services have gone out of their way to take
gender and race out of the test-taking," says Paul Saltman,
a professor of biology at the University of California, San
Diego. "I assume that those tests were not designed with a
gender bias.
"But what isn't unbiased," says Saltman, who has also been
active in reforming science education in local school
systems, "is the environment in which young women grow up in
elementary and secondary schools with respect to how science
is taught to them, how they perceive science, and how their
peers respect girls who are going into science."
Saltman says the bias in the test does speak to cultural
problems more than it does to test-design flaws.
"It tells me that it's not hip, if you're a girl, to be a
scientist," he says. "It's easier to be a male nerd than a
female nerd, if you want to look at it that way, in terms of
the psychosocial values we place on these things.
"It's crazy to worry about whether you fix the exam,"
Saltman adds. "What has to be fixed is how we do science
education."

TI : Environmental Scientists Hail New Forest Service Chief
AU : KAREN YOUNG KREEGER
TY : NEWS
PG : 3
For the first time in its 88-year history, the United States
Forest Service has a research scientist at its helm instead
of an engineer, a forester, or a public administrator.
Environmental researchers are applauding the appointment of
Jack Ward Thomas, a wildlife biologist from Oregon, as a
breath of fresh air for an agency in the midst of transition
from the primarily timber commodity-based outlook of the
past decade to an ecosystem-based approach.
As the new chief, "Jack will be a strong advocate for the
[Forest Service] to do a better job of integrating science
into decisions and policy at the Washington level as well as
activities on the ground," says Charles Philpot, a plant
chemist and station director of the Pacific Northwest
Research Station, the Forest Service (FS) research branch
for Oregon, Washington, and Alaska. "I think we'll see a
shift back to more technical capability on the management
side and more opportunities on the research side to
strengthen our science programs."
Philpot says that this strengthening will primarily manifest
itself in enabling FS researchers to conduct more basic
science, rather than applied studies related to forest
management. However, he adds, "We may be in a position to
hire more scientists, but that's unlikely because of other
constraints on the federal government. What we'll be doing a
lot more of, I suspect, is hiring scientists through
contracts, postdocs, and those kinds of opportunities."
Forest Research, the independent scientific arm of FS and
one of its four divisions, is composed of roughly 700
scientists who conduct research within eight regional
stations and one forest products laboratory; it draws on a
broad spectrum of disciplines, from economics to ecology.
Its roster of scientists does not include researchers who
conduct resource management and technology transfer work.
The agency's research budget is roughly 12 percent of FS's
1994 total appropriated budget.
Many of Thomas's research colleagues outside FS also view
his appointment as a positive move for the agency. Gene
Likens, an ecologist and director of the Institute of
Ecosystem Studies in Millbrook, N.Y., remarks that this "is
a wonderful opportunity for FS to take a new leadership
role," especially by incorporating the concerns of
environmental scientists into consideration of forest
management issues.
Bernard Bormann, a plant physiologist with the Forest
Service Pacific Northwest Research Station laboratory in
Corvallis, Ore., adds that Thomas "can bring a new vision
and develop a new mandate for FS in general, and his call
for developing a new definition of conservation that will
head us into the 21st century is an excellent approach."
Researchers also feel that Thomas's appointment will have
positive implications for scientists outside FS. "I think
we'll see his influence on Congress, for example, in
influencing how politicians might look at political support
for scientific programs.... I think he will be used as a
resource for documenting why it's important for agencies in
the federal government to have independent research arms,"
says Philpot.
In his new position for just over a month, Thomas explains
his approach to the future of FS: "As a scientist, I will
try to ensure that the best science available is brought to
bear on our land-management decisions; but, on the other
hand, I want to make it clear that, at least in my mind,
science is not the overriding factor. Science merely
provides guidance to decision-makers.... Ultimately some
warm human being has to make the decision. These decisions
encompass social values, economic demand, and budgeting and
funding."
Appointment Controversy
Although much of the research community has welcomed his
appointment, Thomas has been directly involved in
controversial plans for managing national forests. These
planning documents advocate a compromise for protecting the
threatened northern spotted owl and its old-growth forest
ecosystems in the Pacific Northwest while reallocating and
decreasing areas of the forests for timber harvest, which in
turn directly affect timber-dependent communities. Last
April, President Bill Clinton selected Thomas as leader of a
team of scientists who would produce a plan for managing
forest ecosystems.
Reactions from the timber community to his appointment as FS
chief run from guarded to negative, concentrating on his
involvement in forestry management issues and the method of
his appointment. At the same time, conservation advocates
are cheering the selection.
Mark Shaffer, vice president for resource planning and
economics with the research division of the Wilderness
Society, a national environmental advocacy group based in
Washington, D.C., asserts that although "we may not fully
agree on the dimensions of the proposed solution to the
ancient forest issue in the Pacific Northwest, Jack Ward
Thomas certainly provided credible leadership in both the
scientific and policy fields ... the kind of leadership the
FS really needs."
On the other hand, Chad Oliver, a silviculturist at the
University of Washington's College of Forest Resources, who
has reviewed forest plans that Thomas proposed, states that
he "is worried that [Thomas] represents a rather extreme
preservationist position, such as those that came out in the
options that he gave" in the ancient forest plan.
William McKillop, a resource economist with the University
of California, Berkeley, College of Natural Resources, who
has also reviewed the Thomas plan, attributes his discontent
with the appointment to the current administration, not
Thomas the scientist, saying, "The issue doesn't concern
Jack Ward Thomas's qualifications ... but rather the choice
of the Clinton administration to require someone who does
not have a timber connection."
Chris West, vice president of the Northwest Forestry
Association, based in Portland, Ore., a timber trade
association that includes biological scientists in its
constituency, says, "The biggest issue to us is for the
first time the chief has become a political appointee,"
referring to another criticism that has been voiced--that
Thomas did not come up through the senior executive service,
a group of high-level administrators from which the Office
of Personnel Management can choose senior government
executives. West adds, "We respect Jack for his expertise
as a wildlife biologist and we'll just have to see, in terms
of [being] an administrator, how he does."
Ecosystem Management
Thomas sees one of his roles as FS head as that of a
synthesizer of the interests of the many groups the Forest
Service of the future must deal with. "We'll take a broader
view of things than we have in the past ... we will
consider conditions over a much longer period ... forests
and lands will be cared for in a way so that they'll be
productive generation after generation," he says. This
philosophy of thinking on a larger scale is called ecosystem
management, a new direction for FS, and, according to
Thomas, also "includes economics and the welfare of people
who are part of that ecosystem."
But Jackie Lang, state coordinator for the Oregon Lands
Coalition, a grass-roots organization representing the
interests of communities based on timber, grazing, mining,
and recreation economies, says, "We're not taking issue with
the fact that science is a critical component in the
decision-making process; however, we reject the idea that
science alone is the decision-maker .... We don't need
a scientist in charge of the FS; we need a public
policymaker who understands the big picture."
Thomas's supporters assert, however, that he indeed has a
solid grasp of the big picture. "One of the things we'll see
from Jack is that he's not going to say that science is an
end-all--he recognizes quite clearly that there are a lot of
things besides science that influence policy and management,
[and] that we have to account for all of them.... I think
Jack Thomas will take the position that both healthy
ecosystems and healthy economies are important ... and he'll
give strong treatment to both," says Tom Hamilton, an
economist and associate deputy chief for research at FS in
Washington, D.C.
Thomas began his career with the Forest Service in 1966 in
Morgantown, W.Va., where he studied forest-wildlife
relationships. From there he worked in Amherst, Mass., in
urban forestry and wildlife biology. Since 1974, he has been
the chief research wildlife biologist and project leader of
the Forestry and Range Sciences Laboratory, a part of the FS
Pacific Northwest Research Station, in La Grande, Ore.
He received his Ph.D. in forestry from the University of
Massachusetts and currently holds adjunct professorships at
four universities. Thomas is author of about 275
publications, primarily in the areas of large-game biology,
wildlife habitat, northern spotted owl management, and land-
use planning.

TI : Naval Lab `Experimentalist' Honored With Bower Award
AU : EDWARD R. SILVERMAN
TY : NEWS
PG : 4
Isabella L. Karle, who pioneered new ways to study the
three-dimensional structure of molecules, making use of both
X-ray and electron diffraction, has been selected to receive
the 1993 Bower Award and Prize in Science.
The four-year-old award, which consists of a gold medal and
a cash prize of $250,000, will be presented in April by
Philadelphia's Franklin Institute Science Museum to honor
outstanding work in the life or physical sciences.The
international committee that chose the 72-year-old chemist,
who becomes the first woman to win the award, said that
Karle is being recognized for facilitating wide-ranging
research in chemistry, biology, and medicine. Her specialty,
three-dimensional molecular modeling--which relies on
detailed X-ray structures to determine accuracy and
parameters--has contributed to the discovery of new
pharmaceutical agents for many diseases.
But Karle, a senior scientist at the Naval Research
Laboratory (NRL) in Washington, D.C., stresses that it was
her husband, Jerome, who developed theories about X-ray
crystallography that she pursued. "I'm an experimentalist,"
she says.
She taught herself X-ray crystallography from textbooks and
then developed techniques for studying crystals, which led
to a greater understanding of their three-dimensional nature
and the effect on physical and biological properties.
"What she came up with is now being used by
crystallographers throughout the world," says Drake
Eggleston, an associate fellow at SmithKline Beecham in
Philadelphia. "We used to have to spend an inordinate amount
of time trying to understand structures. Now our
understanding occurs faster."
Practical Applications
Karle earned her Ph.D. from the University of Michigan, Ann
Arbor, in 1944, when she was 22 years old. At Michigan, she
met her husband, also a Ph.D. student in chemistry. After
graduation, both Karles worked in Chicago on the Manhattan
Project and then returned to Ann Arbor. At the end of World
War II, they went to Washington, where they landed jobs at
the Naval Research Lab, which was willing to hire them both.
"The problem was that we were looking for academic jobs, and
we couldn't get work in the same city," she says, citing as
reasons universities' anti-nepotism policies, bias against
women, and not enough research funding in smaller towns for
both of them.
Her husband--now chief scientist at NRL's Laboratory for the
Structure of Matter--began working on so-called direct
methods for analyzing crystal structures. Along with a
collaborator, Herbert A. Hauptman of the Medical Foundation
of Buffalo, Jerome Karle received a Nobel Prize in chemistry
in 1985 for contributions to crystallography.
In the 1950s, Isabella Karle sought practical applications
for her husband's mathematical theories. In 1963, she
introduced the "Symbolic Addition Procedure," which
revolutionized the types and complexity of problems that can
be solved by analyzing crystal structures.
"She kind of took a chance by being the first one to
demonstrate belief in her husband's theory," says Eggleston.
"Of course, there wasn't much to lose. But direct methods
allow us to solve any structure these days."
In her own research, Isabella Karle has applied the
techniques she developed to the study of a wide variety of
substances. These include crystals distilled from frog venom
that produces toxins--which block specific nerve impulses--
and the rearranged atomic bonds found in thymine, a
component of DNA, when it is irradiated.
Today, Isabella Karle heads the X-ray diffraction section of
NRL's Laboratory for the Structure of Matter. She has been a
member of the National Academy of Sciences since 1978. She's
also served as president of the American Crystallographic
Association.
As for her plans for the prize money, she is rather demur.
"There are many things to do with it," she says, hinting
that she may give some portion of it away. "But I don't want
to promise anything at this point."
Also selected to receive an award from the Franklin
Institute in April is Robert W. Galvin, chairman of the
executive committee at Motorola Inc. of Schaumburg, Ill.,
for his efforts to improve quality and achieve customer
satisfaction while building Motorola into a world-class
semiconductor company. The award to be given to Galvin, the
Bower Award for Business Leadership, does not include a cash
prize.
The Bower awards were established in 1989 as part of the
Benjamin Franklin National Memorial Awards. They were made
possible by a $7.5 million bequest from Henry Bower, a
Philadelphia chemical manufacturer.

TI : NSF's Neal Lane: In Pursuit Of `Strategic Basic Research'
AU : FRANKLIN HOKE
TY : OPINION
PG : 11
-----
Editor's Note: As Neal Lane settles into his new job as
director of the National Science Foundation, his enthusiasm
is tempered by a clear understanding of the formidable
challenges facing him, his agency, and the United States
research community in general.
While confident that the nation can maintain its scientific
leadership internationally, the 55-year-old physicist and
former Rice University provost acknowledges that, if
American science is to fulfill its mission, it must do so in
the context of a rapidly changing global environment, with
all countries seeking to reshape and reidentify themselves
in the post-Cold War world.
Foremost among NSF's objectives, Lane contends, is the
identification and support of scientific endeavors that
accommodate both the individual investigator's inclination
to pursue pure research and the nation's need for
applications of scientific discovery. Such applications
could come, for example, in the form of advanced technology
and commercial products that shore up America's commanding
position in the increasingly competitive world economy.
In discussing agency goals in this regard, Lane uses the
phrase "strategic basic research"--an idea that may well
serve him in his efforts to balance pressures from Congress
for NSF to do more immediately useful work against the
urgings of supporters of basic, curiosity-driven, untargeted
investigations.
In a recent exclusive interview with Senior Editor Franklin
Hoke--conducted shortly after Lane was confirmed by the U.S.
Senate as NSF director--he expressed his views on the
direction that, if he has his way, the agency is likely to
take in the near future. Following is an edited presentation
of that interview.
----
Q Dependable year-to-year federal funding support is, of course,
vital to basic research and other efforts--programs in science
education, for instance. As you look at 1994, do you foresee any
areas where maintaining current NSF support levels may be
especially difficult for you?
A Continuity of support is certainly important to individual
scientists and engineers and also to the programs. But because of
fluctuations in the annual federal appropriation, it's sometimes
a challenge to provide that continuity. Large construction
projects, for example, have to be planned well in advance, and
they have to be funded adequately on an annual basis. Otherwise,
they get stretched out, and the overall cost goes up. In a bad
year they can really squeeze the research budgets. You try to
resist that. But it is a balancing act.
Q What are some of the large projects that you feel must move
forward, even if their high expense would necessitate cuts in
other areas of the NSF budget?
A The one that looms large right now is the LIGO [Laser
Interferometer Gravitational-Wave Observatory] project. That
project is very good science, the timing is right to go forward,
and it's a fully approved project--it's just a matter of getting
the money. I might also mention the FCCSET [Federal Coordinating
Council for Science, Engineering, and Technology] initiatives--
the federal strategic initiatives where the foundation enters
into interagency agreements. These are the things like high-
performance computing and communications, advanced-manufacturing
technology, and advanced-materials processing. We try to meet
those interagency agreements, of course, and in a tight budget
year, that could cause other research that does not happen to fit
within one or another of the strategic definitions of the
initiatives to get squeezed.
Q Regarding priorities, are there any programs for which you
would hope to find more support?
A The area of education and human resources--along with the
FCCSET initiatives I've mentioned--is clearly a high priority for
the country and an area of emphasis for NSF. By continuing to
emphasize these initiatives, we really are doing something that
is very important for the science, engineering, and technical
foundations of the country. I include the national information
infrastructure initiative because high-performance computing and
communications really provide the technical foundation for a much
larger initiative that seeks to bring technology to all aspects
of people's lives--education, health care, and every area in
which information and the rapid transmission of it can be helpful
to the country.
Q Your agency increasingly has become involved in fostering
technology transfer between academia and industry as a means of
strengthening the United States economy. What kind of priority do
you expect to give to technology transfer and related issues of
economic competitiveness?
A Projects that academic researchers work on deal with some very
fundamental or, we sometimes say, foundational questions. These
people are involved in making discoveries about the way nature
works, and many NSF researchers, by working with industry
directly and by educating students who go on to work in industry,
transfer new technologies and knowledge to a whole wealth of
applications, frequently industrial applications. New knowledge
is the goal, and new technology has often come out of the
research process, particularly in the experimental pursuit of new
knowledge. That's why the connections between industry and the
universities are so important. I believe that the only way that
technology really gets transferred is through close interaction
between people. These interactions with industry are very
important for both the universities and the industry.
Now, I think it would be a mistake if we were to change the
objectives of NSF programs so that they were narrowly focused on
producing new technologies and transferring them to industry.
That's not what most university researchers are good at, and
industry knows that. Industry doesn't want to see that kind of
change in the NSF mission; I really don't believe anyone does.
Q But pressure to do more targeted research that will meet
national needs has been growing. What's your view of the pressure
being applied by Sen. Barbara Mikulski [D-Md.] and others in this
regard?
A Over half of the research that NSF supports is strategic or
targeted research, that is, research in fields that have been
identified as being directly relevant to some of the nation's
highest-priority needs. However, the research that is supported
in these areas is very fundamental, and it meets the high
standards of review that NSF requires. Now we are being asked to
see if we can't fund more basic research in strategic areas, and
that request certainly is entirely understandable and not
unreasonable. I don't believe we're really being asked to perform
applied research.
Q You are not, then, anticipating a dramatic change in direction
for your agency?
A The nation has serious problems. All of us should contribute
to their solution in whatever ways we can. The question is, can
NSF do more of that, and I don't know the answer. Perhaps it can.
It's a question of balance. If we can support more strategic
basic research without lowering the standards of merit that have
long characterized the success of the foundation and the
community it supports, then there's no law that I'm aware of that
says exactly what fraction of strategic research it is
appropriate to fund.
Q Much has been said about changes in our national science and
technology goals since the end of the Cold War. NSF is not a
Department of Energy entity, of course, but what effect do you
think the changes on the international scene are having, or will
have, on NSF?
A The strategic initiatives I mentioned earlier are based on
this change in the world. Some of the initiatives have directly
to do with the competitiveness of our country in the global
market, and some of them--those pertaining to the environment,
for example--have to do with the quality of life of U.S. citizens
and other people in the world. The research community will
continue to be asked to provide the underpinnings of the
knowledge base and technology that are important in these various
areas of application. And I expect the research community will be
responsive.
Q How do you regard the notion that this responsiveness, in
terms of practical applications, may compromise or dilute basic,
so-called curiosity-driven research?
A Our scientists, engineers, and educators understand that the
reason the federal government funds their research activities is
because the results of such research are expected to be of value
to the people. What drives them individually is the fundamental
curiosity about how nature works, the opportunity to work with
bright and interesting young people in the universities, and so
forth. But I think researchers entirely understand that the
expectation is that the results of their work are for the good of
humankind. Sometimes, it is hard to predict exactly in what time
frame these results will pay off, but it is expected that
ultimately they will be valuable.
Q The National Academy of Sciences' COSEPUP [Committee on
Science, Engineering, and Public Policy] issued a report last
year [Science, Technology, and the Federal Government: National
Goals for a New Era, Washington, D.C., National Academy Press,
1993] suggesting, that we should fund selected research areas in
which the U.S. can establish clear global leadership. Do you find
this policy framework a useful one?
A We have an international effort here at the foundation and
have had for some time, and I think that international concerns
are going to be as important, if not more important, in the
future than they have been in the past. It is very important that
we maintain good, close interactions between our scientists and
engineers and those in other countries, and exchange ideas and
knowledge. We will be the beneficiary of that kind of openness,
so that's pretty high on my agenda.
The foundation and the science community have long considered
international comparison as one metric for assessing where a
field is at a particular time. There are good reasons for that:
Even if you aren't the world leader in a particular field of
science, unless you have some of the best scientists working in
that area, and you are making discoveries, you really can't take
advantage of discoveries in that field that are made elsewhere.
You must have your people interacting with people in other
countries, working right at the edge of the field, so that as a
discovery is made someplace else it can be picked up here.
Sometimes those discoveries, as I pointed out earlier, are of
immediate importance to one or another application, and the way
to make sure that that application can occur is to be sure that
we have people working right at the cutting edge of that same
area of science.
Q No matter what skills a leader brings to his or her job, there
are limits to what can actually be accomplished. Limiting factors
can include budgetary constraints, institutional inertia, and
policy opposition. Do you anticipate these kinds of broader
impedi- ments in any particular areas that you'd like to succeed
in?
A Realistically, budgets are a constraint. We always have many
more good ideas out there than we can support. That's been true
for a very long time at NSF, so you always feel somewhat
constrained. We set our priorities, and we evaluate programs, and
we believe that we allocate the funds in a way that is in the
best interest of the country in support of science and
engineering. But there are many opportunities that we're really
not able to follow up on just because the funds are limited.
Q Do you expect to see any relief from budgetary constraints in
the near future?
A The nation is having tough times. The economy remains a great
concern, and the efforts to control the budget deficit are
serious and important. So we recognize that there are not likely
to be large increases in many budgets over the next several
years. But I think there is strong support for NSF, I think there
is strong support for the community of scientists and engineers
that we fund, and I think there are great opportunities here for
the future of these fields.
Q Do you need anything from the community of scientists and
engineers in support of what you want to do? Do you need them to
do something for you?
A It is very important that scientists and engineers realize why
the tax dollars of the public are used to support research and
education. I also think that as the mission agencies begin to
develop their programs in support of national needs, it will be
important for the researchers to be responsive. We have many
scientists and engineers out there whose interests could be much
broader, perhaps, than they have been in recent years. There are
real opportunities for those who want to pursue somewhat
different areas of research. So, it would be very helpful if our
colleagues in the universities and colleges would open their
minds to some of these larger questions that society is asking
and that the federal government is trying to address, to see if
there are ways that they can be helpful as individuals or
collectively.
Q Looking ahead, what are your expectations for science in the
U.S.? What do you see in your crystal ball?
A Well, I certainly don't have a crystal ball, but I'm
optimistic about the future of the country and of science,
engineering, and technology in particular. And I base that
optimism on the fact that we do have the finest system of higher
education in the world. We're being very aggressive in addressing
some problems we feel we have in K-12 education. We have a very
strong science and engineering infrastructure in place: the
laboratories, the people, and the educational process. Industry
is reaching out to universities, and universities are responding.
There are examples of partnerships between government and
industry, between different federal agencies, and between federal
and state governments.
In other words, teams are forming, and whenever Americans form a
team, history tells us, they are very hard to beat. So, I feel
quite positive about the future. I expect that we're actually
going to solve some of these major problems.

TI : There Are Reasons For Optimism As We Launch The New Year
AU : Eugene Garfield
TY : OPINION (COMMENTARY)
PG : 12
Although the United States research community had its share
of problems during 1993--a depressed job market,
congressional budget cutting, the demise of the
superconducting supercollider, and so forth--it was a banner
year in many respects, as well, yielding abundant cause for
us to be optimistic as we enter the new year.
Our hopes should by buoyed, for instance, by the knowledge
that the National Institutes of Health is now led by Harold
Varmus, a distinguished biologist. Varmus appears eager to
defend the clear merits of basic biomedical investigation
and to voice the demand, on behalf of the nation's bench
scientists, for the financial--and philosophical--support
that curiosity-driven research clearly deserves.
Not unrelated is the sense of confidence we can gain from
the recent appointment of Neal Lane as director of the
National Science Foundation. On page 11 of this issue, we
present an exclusive interview with Lane, who also appears
to understand the value of untargeted research. Lane, of
course, will have his hands full in his efforts to
accommodate the interests of pure research while under
pressure from powerful figures in government and industry
who insist that federally supported science must have a
practical, fiscal, near-term--if not immediate--payoff.
Also most gratifying during the past year was the momentum
achieved by those organizations and individuals dedicated to
the eradication of sexual harassment from the scientific
workplace and the fair treatment of women researchers. The
articles on the front page of the current issue underscore
the progress that's being made regarding these concerns; the
elaborate projects under way at the Association for Women in
Science and other organizations, along with evidence of a
rising consciousness throughout the science community, are
indeed heartening.
Looking back over The Scientist's coverage during 1993, I
remain particularly encouraged by a front-page photo we ran
in our October 18 issue: It pictured Hillary Rodham
Clinton gazing admiringly at Mary Lasker, a long-time
supporter of basic research; the captured moment signaled to
me that the interests of the nation's individual
investigators have an appropriately high position on the
Clinton agenda.
The interests of biomedical scientists are of vital concern
to me, as publisher, since the overwhelming percentage of
our 50,000-plus readers are NIH grantees--among them more
than 90 percent of the members of the Federation of American
Societies for Experimental Biology and of the American
Federation for Clinical Research. Members of these two
groups alone account for a huge percentage of NIH extramural
grants, not to mention grants from such private foundations
as the Howard Hughes Medical Institute. While a significant,
and increasing, number of our readers are industry-supported
researchers, it should be clear that the prospects for The
Scientist's continuing success are closely intertwined with
the professional prospects of our academic readership, as
well, and their success in securing NIH's support.
Repeated studies give me good reason to believe that The
Scientist plays a unique role as a vital news and opinion
source for America's scientific community. While we all
suffer from information overload, our readers tell us that
they find our publication both useful and enjoyable. In
1994, we'll continue our in-depth coverage of major news
events, employment-related issues, research breakthroughs
and emerging patterns, and the latest innovations in
laboratory tools and technology. And we'll continue
presenting incisive opinions and commentaries by and about
the men and women who are shaping the science community.
Many uncertainties face us all as we enter the new year. We
can only hope, for instance, that the sluggish U.S. economy
will regain energy; we can only hope that President
Clinton's health care reform and free-trade programs will
materialize as beneficial for both science and society; and
we can only hope that Congress will play a proper role in
supporting the nation's research activities.
As the year progresses, The Scientist's readers can depend
on us to keep them up to date on these and other crucially
important matters. At the same time, we at The Scientist
will depend on our readers to keep us up to date on their
personal views concerning the issues of the day as well as
their reactions to our publication.

TI : Integrated Education
AU : J.D. ANDRADE
TY : OPINION (LETTERS)
PG : 12
I enjoyed your Opinion page in the Oct. 18, 1993, issue,
written by six students from the University of Miami [R.
Andreasen, et al., page 11]. Their perspective, their
diagnosis, and their recommen- dation for treatment of high
school education is insightful and, from my experience, most
appropriate. Our own small effort, the Center for Integrated
Science Education at the University of Utah, is focused on
applying most of their recommendations at the elemen- tary
and junior high level. We have found that the teachers and
the public education community in general are very
responsive to our initiatives and generally want to enhance
the educational experience for their students.
A major part of the problem in major research universities
is the way science is taught. At our institution, we are so
stringently organized along departmental lines that only the
most interdisciplinary individuals have an interest in
looking at science in a more integrated fashion--in relating
their expertise to other courses and other subjects. "Cold
fusion" could have originated only in a university where
physicists and chemists rarely communicate. There are very
few institutional incentives to facilitate interdisciplinary
communication.
It is therefore difficult for a high school teacher who
obtains his or her credentials from such an institution to
effectively involve students or to integrate science in the
high school environment.
None of this will substantially change until department
chairpersons, deans, vice presidents, and presidents of
major research institutions do more than give lip service to
these problems. Until that happens, only a small fraction of
the faculty will have the commitment, the foresight, and the
uncommon sense to involve their students in science in the
manner so eloquently presented by those six Miami
undergraduates.

TI : Gel Scanners
AU : GREGG HOFF
TY : OPINION (LETTERS)
PG : 12
I disagree with the evaluation of gel scanner systems in the
Oct. 4, 1993, issue of The Scientist [C.D. Potter, page 18].
The article states that gel scanners are "expensive" when
compared to gel documentation systems. This statement is
potentially misleading.
The article does not distinguish between gel documentation
systems, which primarily perform one function, and gel
scanners, which may perform a wide range of functions,
including analysis, databasing, and documentation.
Dedicated gel documentation systems may be the best choice
for labs that need only documentation. But for labs that
need documentation and analysis, a gel scanner system with
documentation capabilities may be a cost-effective option.
If you wanted to focus on only one type of system, you
should have either omitted reference to gel scanners or
explained how the systems are used for other applications.
Dismissing the systems as merely "expensive" is a disservice
to readers.

TI : Fetal Tissue Ethics
AU : ROLAND F. HIRSCH
TY : OPINION (LETTERS)
PG : 12
I read the article on fetal tissue research in your October
4 issue [M.E. Watanabe, page 1] with interest. However, it
is not a balanced picture of this topic. Reputable medical
researchers have expressed doubts about the potential
utility of fetal-tissue transplants. The article should have
included these viewpoints.
The more serious flaw in the presentation was its lack of
consideration of ethical issues. The moratorium referred to
in the article was on research with tissue from induced
abortions, not on all research in this field. There are
legitimate concerns that clinical use of fetal tissue for
transplants will in many cases require scheduled (not
elective) abortions. Indeed, it is difficult to imagine a
brain surgery team waiting for an abortion to just happen so
that the tissue is available for their use. The scheduling
problem will lead to women being recruited and paid to have
abortions. What controls could prevent this, considering the
frequency with which existing regulations, such as on late-
term abortions, are violated?
A related concern is that some proposed transplantation
procedures would require tissue from babies late in
pregnancy, often in the range at which they could live if
born. Should young lives be sacrificed to potentially help
older people?
I do not believe that medical researchers should blindly go
ahead to develop procedures that could violate the standards
that make us civilized. The author should have offered
references for readers interested in the question.

TI : Defense Giants Face Post-Cold War Research Challenge
TY : RESEARCH
PG : 15
Editor's Note: Now that the Cold War is history, it's clear
that the United States' mighty defense and aerospace firms
increasingly will be pursuing profit in areas other than the
development of military weaponry. According to the
newsletter Science Watch--published by the Institute for
Scientific Information (ISI) in Philadelphia--the
effectiveness with which these corporations refocus their
product-development attention from swords to plowshares is
likely to depend greatly on their basic scientific research
capabilities. To gain insights on the research strengths of
nine defense and aerospace giants, the newsletter undertook
a study of their 1981-92 journal citation records. Following
is Science Watch's report (4[1]:1-2, 1993), reprinted here
with permission of the newsletter and ISI.
Many defense and aerospace firms in the United States and
other nations are quickly discovering what it takes to
survive in a post-Cold War world--and it's not business as
usual.
As a wave of articles in financial and trade publications is
telling us, many defense contractors have responded to
slackening demand by selling off peripheral or weak business
lines (often to their stronger competitors); by attempting
to redirect their military manufacturing capabilities to
civilian projects; and, generally, by downsizing.
To twist a familiar phrase, defense companies are starting
to worry and learning how not to love the bomb so much.
During these times of turbulent transition, each defense
company will be scrutinizing its scientific and
technological base to determine how best to adapt to the new
environment. While aircraft and weapons manufacturers are
quintessential technology shops, technology is to some
degree dependent on basic research and scientific expertise.
The research activities of a firm may be only partly--or at
times even poorly--reflected in the pages of the journals
indexed by ISI for its Science Citation Index, especially if
they represent proprietary knowledge or classified work that
may be actively kept from public view. But even a partial
picture may be sufficient to indicate areas of significant
activity and strength.
With these limitations in mind, Science Watch reviewed the
publication records of nine leading U.S.-based aerospace and
defense contractors to assess their research performance
over the last decade, to determine their relative rankings,
and to identify areas of strength for each. All journal
articles by these companies, published between January 1981
and June 1992, were extracted from ISI's Science Indicators
Database, and their citation counts were tabulated.
The results of this analysis show that Rockwell
International Corp. and Lockheed Corp. stand out as the
research leaders in the group. Papers from both companies
attained the highest citations-per-paper averages (reflected
in the citation impact column on the accompanying table),
and their citation impact scores rose steadily since the
period 1983-87. General Dynamics Corp., by contrast,
achieved a relatively low, albeit consistent, altitude in
terms of citation impact.
The table provides further statistics, such as the
percentage of papers published from 1981 through June 1992
that remained uncited by the end of June 1992, and the
percentage of a firm's papers cited 25 times or more. Both
tend to correlate with the ranking by citation impact. For
example, Rockwell International, first in citation impact,
exhibits the lowest percentage of uncited papers and the
highest percentage of papers cited 25 times or more. General
Dynamics, on the other hand, the lowest ranked in the group
in impact, exhibits the highest percentage of uncited papers
and the lowest percentage of highly cited papers.
Although all nine companies operate within the same business
sector, their research activities differ significantly. And
since different fields of research show different average
citation rates, the rank order of the companies in terms of
citation impact should be viewed as only a partial indicator
of research strength. To the extent that any company
publishes exclusively or disproportionately in a low-impact
area, such as aerospace engineering, it would suffer in
comparison to a firm that is active in one or more higher-
impact fields, such as condensed-matter physics.
What is perhaps the most telling scientometric statistic of
a company's research strength is how its citations-per-paper
record, at whatever level characteristic for its mix of
research, changes against itself over time.
An examination of the highly cited papers for each company
reveals the following:
* Rockwell International shows significant strength in
semiconductor research, especially in studies of gallium-
arsenide materials, and in ceramic-based composite
materials.
* Lockheed researchers have been particularly active in
exploring the new high-temperature superconductors, as well
as in a variety of astrophysical experiments in collab-
oration with the National Aeronautics and Space
Administration and academic institutions.
* McDonnell Douglas Corp.'s diverse research record includes
studies of semiconductor materials, structures, and
fabrication techniques; plasma physics; and lithium niobate
materials.
* Martin Marietta Corp. scientists have been focusing on
aluminum powder metallurgy technology; surface science
topics, such as metal-polymer bonds; and plant science,
especially photosynthesis.
* Raytheon Co. researchers published extensively on metal-
organic vapor deposition of thin films.
* Boeing Co. focused sharply on materials science and X-ray
absorption spectroscopic studies of various compounds. Its
researchers were also active in knowledge acquisition
algorithms for expert systems.
* Northrop Corp. researchers consistently published papers
dealing with pulsed excimer lasers, gyrotrons, and optical
storage devices and pattern recognition.
* Grumman Corp. papers reveal a particular interest in A1-
based alloys, in photovoltaic cells, and in fusion research.
* General Dynamics researchers also explored A1-based
alloys, as well as crack propagation in various materials
and pattern recognition algorithms.
What, overall, are the main areas of research in the defense
and aerospace labs? A study of the most frequently cited
papers published between 1988-92 reveals the following
subjects: condensed-matter physics, especially
superconductivity; aspects of semiconductor science,
especially GaAlAs/GaAs structures; thin-film preparation
techniques; composite materials; optical data storage; and
astrophysics.
Many pundits predict problems for defense contractors who
hope to shift from military to civilian manufacturing. While
the challenges are great, the specialized scientific and
technological expertise these firms possess remains one of
the U.S.'s most valuable assets. If these assets are smartly
managed, they may produce significant returns, not just on
the military side but on the civilian side of the economy,
as well.

Pfahl, "Retinoid X receptor is an auxiliary protein for
thyroid hormone and retinoic acid receptors," Nature,
355:441-6, 1992.
Magnus Pfahl (La Jolla Cancer Research Foundation, Calif.):
"Thyroid hormones as well as the vitamin A-derived hormones
(retinoids) influence a myriad of biological processes,
including such complex programs as metamorphosis and
morphogenesis. Retinoids have also drawn particular
attention in recent years because of their effectiveness
against a number of skin diseases (including wrinkles) and
their potential as anti- cancer and cancer-preventive
agents. However, use of retinoids and thyroid hormones as
therapeutics has been hampered by undesirable side effects--
which, for instance, in the case of retinoids range all the
way from slight skin irritations to malformation in fetuses.
Because of the manifold roles of both thyroid and retinoid
hormones, and their potential as therapeutics, their
mechanism of action has been of particular interest.
"A major advance toward understanding this was achieved by
the cloning of specific nuclear receptors. The receptors
turned out to belong to a large family of transcription
factors that also included the steroid hormone receptors. In
concert with their multiple biological roles, multiple
receptors were found to exist: two thyroid hormone receptors
(TRa and TRb) and six retinoid receptors. The retinoid
receptors fall into two groups, the retinoic acid receptors
(RARa, b, and g) and the retinoid X receptors (RXRa, b, and
g). Since these receptors were structurally related to the
steroid hormone receptors, it was first believed that they
also functioned like those--that is, bind as homodimers to
specific DNA sequences (hormone response elements). However,
it turned out that TRs and RARs (as well as RXRs) were
relatively poor DNA binders but that their binding in vitro
could be enhanced by nuclear protein extracts. This
indicated that the mechanism of action was more complex and
required another protein for efficient DNA recognition.
"In our paper we show that RXR is this nuclear factor. Thus,
RXR, itself a retinoid receptor that requires 9-cis retinoic
acid for activation, can serve as a coreceptor for TRs and
RARs, receptors that belong to the same subfamily but are
activated by very different hormones. An RXR homologue is
already found in Drosophila (while TRs and RARs do not exist
in insects) and has now also been shown to function there as
the partner for the ecdysone receptor. Not surprisingly,
then, its role in higher vertebrates turned out to be very
broad, as RXRs were found to heterodimerize with the vitamin
D3 receptor (VDR) as well as with the peroxisome
proliferator-activated receptors (PPAR). Thus, RXRs play a
very central role; by heterodimerizing with several hormone
and vitamin receptors, they may in fact allow crosstalk
between a variety of hormonal pathways and allow an enormous
diversity of transcriptional controls. This may account for
the pleiotropic effects of these hormones and vitamins.
"Because of RXR's central role, we were also particularly
interested in the effect of RXR-specific ligands.
Surprisingly, we observed 9-cis RA-induced RXR homodimers
that act on a subset of retinoic acid-responsive genes (X.-
k. Zhang, et al., Nature, 358:587-91, 1992). Thus, an
additional retinoid response pathway exists that is
controlled by homodimers. We subsequently were able to
design retinoids that are selective for RXR homodimers (J.M.
Lehmann, et al., Science, 258:1944-46, 1992). Retinoids that
induce RXR homodimers can decrease the RXR availability for
heterodimerization, and we have recently observed that,
indeed, 9-cis RA- and synthetic RXR-selective retinoids can
inhibit the thyroid hormone response (J.M. Lehmann, X.-k.
Zhang, G. Graupner, et al., Molecular and Cellular Biology,
13:7698-7707, 1993).
"Overall, the discovery that RXR is an essential partner for
a number of hormone and vitamin receptors by us (and several
other laboratories at essentially the same time) reignited
tremendously research in this area. A major challenge for
the future will be to harness this knowledge into
hormone/vitamin-derived therapeutics with optimal efficacy
and minimal side effects. For the retinoids, this seems at
last now to be feasible."

E.E. Farmer, C.A. Ryan, "Octadecanoid precursors of a
jasmonic acid activate the synthesis of wound-inducible
proteinase inhibitors," Plant Cell, 4:129-34, 1992.
Clarence A. Ryan (Institute of Biological Chemistry,
Washington State University, Pullman): "The understanding of
signaling pathways that regulate genes in response to
environmental and developmental signals is a central theme
in plant biology. How plants regulate genes in response to
insect and pathogen attacks is important to the
understanding of both intercellular and intracellular
signaling circuits that are fundamental to the plant's
survival, as well as in applying this knowledge to improve
crop productivity. Recent research in our laboratory has
revealed that an 18-amino-acid polypeptide called systemin
as well as a small cyclopentanone called jasmonic acid and
its methyl ester, methyl jasmonate, are powerful inducers of
the synthesis of two serine proteinase inhibitor proteins,
called inhibitor I and inhibitor II, that are synthesized as
defense proteins in response to insect and pathogen attacks.
"We subsequently found that linolenic acid and two
intermediates of the biosynthetic pathway between linolenic
acid and jasmonic acid are also inducers of the two
proteinase inhibitor genes when simply applied to the
surface of tomato leaves. The various signaling compounds
were incorporated into a hypothetical pathway for proteinase
inhibitor gene activation in response to insect and pathogen
attacks. In this model, extracellular signals released from
attack sites, such as oligouronides (plant cell wall
fragments) and the polypeptide systemin, are proposed to
interact with the receptor cell membranes to activate a
lipase. The lipase in turn is hypothesized to hydrolyze
membrane lipids, releasing linolenic acid, which is rapidly
converted to jasmonic acid. Jasmonic acid is proposed to
interact with factors to activate the inhibitor genes.
"The model so far has been supported by several reports that
have demonstrated an increase in intracellular jasmonic acid
in response to wounding or to various defense signals in a
variety of plant species. Jasmonic acid is now known to
activate many other types of defensive genes in plants. The
molecule had previously been shown to activate the synthesis
of storage proteins in plant leaves and had been proposed as
a plant growth and senescence regulator. Our paper, in
presenting a model signaling pathway for jasmonate synthesis
in response to signals, has generated a great deal of
interest in the possibility that signaling pathways for
other plant genes involving environmental and developmental
signals may have similarities to those described in our
model.
"As the model is more thoroughly understood, it should
provide our first detailed understanding of a signaling
pathway in plants in which signals that are produced by a
known stimulus result in the activation of nuclear genes."

TOOLS & TECHNOLOGY

TI : DNA Probes Yield Expanded Research And Clinical Uses
AU : RICKI LEWIS
TY : TOOLS & TECHNOLOGY
PG : 17
As the growing numbers of molecular biologists well know,
their art and laboratory craft depend on the extrusion of
information residing in nucleic acid sequences. It follows
that the tool that's come to be known as the DNA probe--a
piece of single-stranded DNA that seeks out its
complementary sequence in a biological sample--has become
increasingly important to them.
The capabilities of probes have expanded rapidly in the past
few years, and they have become easier to use. These
developments have benefited not only basic researchers, but
also those engaged in specifically directed investigations--
in diagnostics, forensics, and epidemiology, for example.
The technology's applications continue to increase, and DNA
probes are now "well entrenched" in molecular biology labs,
according to John Sninsky, senior director of research at
Roche Molecular Systems, Alameda, Calif. In the research
community, he says, investigators are being stimulated to
use the probes in more and more "wild and wonderful ways."
A DNA probe may be a chain of as few as 15 nucleotide bases,
the molecular building blocks of DNA and RNA, or it may
stretch to thousands of such bases. The usefulness of the
probe technology, researchers say, comes from the inherent
tendency of these single-stranded nucleic acids to seek and
hybridize to their complementary sequences, following the
base-pairing rules that guide the formation of the DNA
double helix--adenine with thymine, and cytosine with
guanine.
A list of the methodologies dependent on DNA probe
technology reads like a table of contents in a molecular
biology text: Southern blotting (to detect other DNAs),
Northern blotting (to detect RNA, measuring gene
expression), colony and plaque hybridization (to spot
bacteria and viruses), in situ hybridization (to highlight
DNA sequences directly in cells), footprinting (identifying
the sites where certain proteins bind DNA), mapping genes,
and sequencing genes.
Even in the case of the polymerase chain reaction (PCR), the
widely used lab process that won its inventor Kary Mullis a
1993 Nobel Prize, the primers used--short pieces of DNA--are
essentially DNA probes bracketing sequences to be amplified.
"DNA probes and PCR are inextricably linked at the hip,"
says Sninsky.
Clinical Success, Research Staple
DNA probes are farther from the public eye than some other
biotechnologies, such as cloning human embryos or
genetically engineering tomatoes. They are nonetheless very
much in the news, especially as diagnostic tools.
They were used, for instance, to help track down the sources
of bacterial contamination in hamburgers served by a fast-
food chain that caused illness last spring, and they have
been used to analyze contaminated municipal water supplies.
DNA probes also helped researchers investigating the
hantavirus pulmonary disease that struck the southwestern
United States last year.
"They identified the virus initially using serology, but
they quickly used DNA probes to identify the group of
viruses to which it belonged," says Sninsky. The information
showed that the condition had indeed been seen before.
Sninsky says that this capability of DNA probes to precisely
identify a pathogen, even the particular strain of that
pathogen present in a given patient, is a critical one. With
both reemergent tuberculosis and AIDS, for example, the
disease-causing targets of potential therapies are
constantly changing, mutating to present new characteristics
to researchers and physicians.
"Mutations are responsible for microbial resistance to
drugs," Sninsky explains. "If you don't detect a drug-
resistant pathogen before you treat the patient, you could
be exposing him or her to side effects without [a
corresponding] benefit."
DNA probes were one of the first biotechnologies to
successfully negotiate the passage from the laboratory to
the clinic. One reason is that, compared with traditional
microbiological detection tests, DNA probes generally offer
both greater specificity and higher sensitivity. Also, the
costs of most commercially available probe systems for
specific targets range between about $150 and $400, making
them affordable for many laboratories.
With standard tests, "there's a limitation in certain
patients, where there is not enough antigen or antibody
detected," according to Larry A. Risen, marketing manager at
San Diego-based Gen-Probe Inc. "But with DNA probes, you can
amplify material or use kinetics" to yield a diagnosis,
Risen says.
Gen-Probe has focused its efforts on developing and
marketing DNA probes targeted to common infectious
disorders, such as those caused by streptococcus,
enterococcus, Hemophilus influenzae, and several sexually
transmitted diseases.
'A new probe-based test from Gen-Probe may help clinicians
in their efforts to confront reemergent, drug-resistant
tuberculosis. The probe is just entering trials in the U.S.,
having shown in European trials that it can greatly speed
diagnosis over traditional culturing methods. Called the
Amplified Mycobacterium tuberculosis Direct Test (MTD), the
probe is capable of identifying the strain of tuberculosis
present in about five hours, instead of up to eight weeks
with the culturing methods, helping physicians prescribe
appropriate treatments sooner.
"The test represents a breakthrough in adapting [this]
technology to routine clinical use," said Mathew Longiaru,
Gen-Probe's director of research and development, in a
statement. "Designed specifically for the clinical
laboratory, the test is not as burdensome as some
complicated research methods."
Some companies focus on probes for research purposes,
although they also may offer one or two for diagnostic uses.
For example, Oncogene Science of Cambridge, Mass., offers
research probes for a wide range of human genes, including
interleukins, interferons, colony stimulating factors,
myosin, tubulin, and oncogenes. The Food and Drug
Administration also has cleared for marketing the company's
Trans-Probe-1, which targets the site where pieces of
chromosomes 9 and 22 join in 90 percent of patients who have
chronic myelogenous leukemia. The classic test to spot this
so-called Philadelphia chromosome, discovered in 1959 by
Peter C. Nowell and David A. Hungerford (Science, 132:1497,
1960), is to prepare a chart of all of the chromosomes, then
search for the unusual joining--a much more painstaking
task.
Similarly, most products from Oncor Inc. of Gaithersburg,
Md., whose specialty is in situ hybridization, are for
research use only, but the company does have FDA approval
for an in vitro diagnostic kit to detect rearranged
chromosomes in certain white blood cell cancers.
Many DNA probes are available for research or
investigational uses, but with clinical applications clearly
in mind. GeneMed Biotechnologies, for example, offers probes
to the human genes for beta globin, the cystic fibrosis
transmembrane regulator, and key immune system proteins. As
a group, these probes target inherited disorders. The
company also markets infectious disease probes to the
viruses causing hepatitis, herpes, and rubella, as well as
the microbe that causes chlamydia.
Straddling the research-clinical line even more closely are
the companies using FISH (fluorescence in situ
hybridization) technology to speed fetal chromosome checks.
The In-Sight system from Integrated Genetics of Framingham,
Mass., highlights chromosomes 13, 18, 21, X, and Y--those
most likely to be present in extra copies in fetuses--by
using three to five DNA probes per chromosome. They offer
this service on an investigational basis, as an adjunct to
the conventional approach, which requires a week to culture
cells from amniotic fluid.
Brian Ward, director of the cytogenetics lab at Integrated
Genetics, says that FDA approval for In-Sight is not
required. FISH, he says, "is called `home brew technology.'
FDA will only certify drugs and medical devices that are
marketed and sold. It doesn't regulate services." He notes
that states, however, may regulate such services.
Integrated Genetics' concentration on the chromosomal
anomalies most commonly seen in fetuses reflects its
clinical bent. But FISH technology also can distinguish
among all 24 types of human chromosomes, making it useful in
many research areas and in detecting rare or highly specific
abnormalities.
"It is the same technology, but using different sequences
and different applications," says Ward. Researchers at
Lawrence Livermore Laboratory in Livermore, Calif., for
example, have developed what are called "whole-chromosome
paints," which target repetitive DNA sequences. "These light
up each chromosome from one end to the other. In contrast,
ours are specific, brilliant, and intense, a small pinpoint
of light in a nucleus," Ward says. Oncor's FISH system
targets unique DNA sequences and currently identifies 19
human chromosomes.
Oncor's newest probes detect genes currently at the
forefront of genetic research, including those behind the
Prader-Willi/Angelman syndromes, in which a small deletion
in chromosome 15 causes differing symptoms depending upon
which parent transmits it; and XIST, the site on the X
chromosome that triggers one X to be shut off in cells of
female mammals. They also have probes to telomeres, the tips
of chromosomes that are important to their stability and are
being intensively studied.
Farewell To Radioactivity
As a research tool, DNA probes are the latest in a long
series of techniques to isolate and describe biological
functions by labelling and tracking various biological
molecules. Probes can carry different kinds of additional
chemical marker units that allow researchers to locate and
quantify them and their targets.
Although biologists and chemists have attempted to unravel
various metabolic reactions since early this century, it
wasn't until World War II that research in nuclear physics
made radioactive materials readily available. This, in turn,
allowed radiolabeling of biomolecules, and this led to new
kinds of biological experiments. Radioactively labeled
isotopes can be detected through their ability to expose a
photographic emulsion on film, or by the alteration of the
density of DNA incorporating them.
Many of the key experiments that laid the groundwork for
molecular biology followed labeled DNA, for example. Often
an isotope of phosphorus, 32P, was used, which labels the
sugar-phosphate backbone of the molecule. The fact that the
genetic material in a cell is DNA and not protein was
discerned in the so-called blender experiments of Alfred
Hershey and Martha Chase in 1950. They tracked and
distinguished DNA by labeling phosphorus, and protein by
labeling sulfur (A. Hershey, et al., Journal of General
Physiology, 36:39-56, 1952). Matthew Meselson and Franklin
Stahl later revealed the semi-conservative mode of DNA
replication by differentially labeling nitrogen and
following the densities of daughter DNA strands (M.
Meselson, et al., Proceedings of the National Academy of
Sciences, 44:671-682, 1958).
Using radioactive isotopes has obvious drawbacks, however.
The beta particles emitted by 32P are so energetic that the
signal on photographic film can be too fuzzy to be
meaningful. Richard Rhodes, technical service representative
at Promega Corp. of Madison, Wis., claims that his company's
LIGHTSMITH I System, which uses chemiluminescence to label
DNA, is much easier to use than traditional 32P labeling.
LIGHTSMITH is a direct, nonisotopic alternative to
radioactive labeling, which means that the chemical that
generates the signal is conjugated directly to the probe.
Specifically, alkaline phosphatase is hooked to the probe.
This enzyme catalyzes removal of a phosphate from a
proprietary chemiluminescent compound. The resulting light
emission marks the probe's presence.
"You don't have to deal with handling or disposal, as you do
with radioactive labels," Rhodes says. "And we've found that
our probes display a higher level of sensitivity than
radioactively labeled probes."
Another direct approach to tagging DNA probes is the Prime-
It Fluor Random Priming kit offered by Stratagene Corp. of
La Jolla, Calif., which incorporates a fluorescently labeled
nucleotide into the DNA. Commonly used fluorescent markers
include fluorescein, which emits yellow-green when excited
with blue light, and rhodamine, which emits a deep red.
Most nonisotopic labeling systems, however, are indirect,
with the probe bound to a molecule that is attracted to a
second molecule that is itself bound to the signaling
enzyme, usually alkaline phosphatase. In the most common of
these strategies, the DNA probe is immobilized on a support
and bound to biotin (a small, water-soluble vitamin). Biotin
binds strongly to the bacterial protein streptavidin, which
is linked to alkaline phosphatase. Such streptavidin-
biotinylated DNA probes are offered by Genemed
Biotechnologies Inc. of South San Francisco, Calif.; United
States Biochemical of Cleveland; New England BioLabs Inc. of
Beverly, Mass.; and others.
As popular as DNA labeling with biotin-streptavidin is, it
is gradually being replaced by what some researchers say is
a better alternative--digoxigenin, a derivative of the
foxglove plant.
The digoxigenin molecule binds DNA at one site and a highly
specific antibody at another. The antibody is the part that
is detected. Charles Schroeder, technical service specialist
at Indianapolis-based Boehringer Mannheim Biochemicals,
which produces digoxigenin, explains that its success is due
to its uniqueness.
"Many of our customers had noted that because biotin is a
vitamin, it is endogenous to many [animal] systems,"
Schroeder says. "But digoxigenin is found only in the
foxglove plant."
As a result, there is less background interference caused by
the antibody binding elsewhere than to the DNA sequence
labeled with digoxigenin.

PROFESSION
------------------------------------------------------------
TI : Corporate Board Membership: Enriching In More Ways Than One
AU : ROBERT FINN
TY : PROFESSION
PG : 21
Imagine a position that requires a commitment of just four
to 10 working days most years, yet pays up to $60,000--plus
stock options. Imagine further that this position allows you
as a scientist to observe the inner workings of the
industrial culture of the United States, to make personal
contacts with powerful businesspeople, and to influence the
direction of a major corporation. Such is the lot of the
scientists who sit on the boards of directors of public
companies.
Allen Misher, president of the Philadelphia College of
Pharmacy and Science, says of his work on corporate boards,
"The quality of the people I deal with, the intellectual
interactions, are extremely important to me and highly
enjoyable. It gives me an opportunity to deal on a
scientific basis with people at the forefront of their
disciplines. It's even fun on a personal basis."
While the scientists who are asked to serve on corporate
boards find the experience to be enriching from a
professional as well as a financial perspective, some
outside observers caution that such arrangements can lead to
dangerous conflicts of interest. "In [a] company, the
interest is in getting a product to market," says Sheldon
Krimsky, a professor and chairman of the department of urban
and environmental policy at Tufts University. "In the
university, presumably, the main interest is the pursuit of
truth."
A conflict can occur, for example, when a scientist with a
financial interest in a company must evaluate research--
either in his or her own lab or on a peer-review panel--
related to the company's business, Krimsky says.
Yet Alan Schriesheim, director of the Argonne National
Laboratory in Illinois and a member of two public boards--
those of Rohm & Haas Co. of Philadelphia and Hollywood,
Fla.-based HEICO Corp.--says that when a scientist serves as
a corporate director, his or her ability to function
effectively as a researcher is enhanced. "It provides the
scientist with a look at what one would consider to be the
`real world'--what does it actually take to market and sell,
and what are the risk/benefit trade-offs?" Schriesheim says.
"It gives you exposure to the very interesting problems
industry has that require technical solutions. It's a
generally broadening experience. The contact with other
board members who are senior people in other industries--
banking, for example--makes the scientist a more rounded
person. If he's an academic, it puts him in a better
position to advise his students on career paths. It provides
him with contacts that are helpful to his students and his
colleagues."
"I look forward to [board] meetings," says Misher, who
currently serves on the boards of three public companies--
U.S. Healthcare Inc. of Blue Bell, Pa.; U.S. Bioscience Inc.
of West Conshohocken, Pa.; and MARSAM Pharmaceuticals of
Cherry Hill, N.J.--and several private ones. "It's such a
dramatic change of pace from the normal academic life that I
find it extremely stimulating," Misher says. It's high-
energy, and decisions are made promptly."
Of course, it is the rare scientist who gets to receive
these benefits. Few corporations have scientists as
directors. The ones that do--primarily those that are
heavily dependent on technology--usually have only one
scientist among the bankers, venture capitalists, and
captains of industry who form the backbones of most boards.
Scientists At The Top
Generally, in order to be considered suitable to serve on a
board of directors, a scientist must have established a
national reputation on the basis not only of scientific
achievements, but also of administrative and managerial
skills. Furthermore, it helps to have spent a good portion
of one's career outside the ivory tower. Misher, for
example, spent 18 years with Philadelphia-based SmithKline &
French Laboratories (now part of SmithKline Beecham), where
he started as a pharmacologist and went on to increasingly
responsible management positions, ending up as a group vice
president. Schriesheim spent 27 years at the Florham Park,
N.J.-based Exxon Research & Engineering Co. and two years as
the director of Argonne before being asked to join his first
board.
The administrative experience is important, because the
responsibilities of a board member go far beyond providing
the occasional nugget of scientific advice--many companies
have scientific advisory panels for that. Board members need
to be conversant with profit-and-loss statements, audit
reports, and strategic plans, since they are charged with
nothing less than overseeing all major corporate functions.
Mark P. Kriger, an associate professor of management at the
State University of New York, Albany, and an expert on
strategic management, says that the formal responsibilities
of a board of directors include the following:
* maintaining, revising, and enforcing the corporate charter
and bylaws;
* delegating special powers to corporate officers, such as
the power to sign contracts, establish bank accounts, and
sign checks;
* approving important financial decisions, such as those
pertaining to budgets, capital appropriations, and officers'
compensation;
* examining the results of outside audits;
* safeguarding and approving changes to corporate assets;
* electing and advising corporate officers; and
* ensuring the maintenance of a sound board through regular
elections and the filling of vacancies.
"In a legal sense, board members are the ultimate purveyors
of the corporate charter," says Kriger. "They are legally
responsible."
If a company is well run, these responsibilities can be
exercised during the regular board meetings, which are
usually held quarterly, or at most monthly.
"On occasion there are special assignments that might take a
day or two longer," notes Misher. "In one company, another
board member and I took on the assignment for the chairman
of a very intensive review of their R&D efforts. With some
outside help, that took us maybe a week's worth of sitting
down and reviewing all of the R&D projects, very carefully,
very intensively." But that's unusual.
"You each receive a `board book' a week or so prior to [a]
meeting, providing a host of background on each of the
agenda items," Kriger says. "This gives you the opportunity
to read through it, think about it, [and] make a phone call
or two if you're not certain as to some of the issues
raised."
Legal Responsibilities
But if a company runs into trouble for one reason or
another, the amount of work can increase greatly. Says
Misher, "You've got to remember that, particularly in the
state of Pennsylvania--and probably elsewhere--there are
legal responsibilities. If you are the director of a public
company, you are legally responsible for representing the
best interests of the shareholders. That is a serious
responsibility, and in order to execute that responsibility
you must ensure that you are knowledgeable about the
operations of the company and its controls and the way it
manages its business."
Soon after Schriesheim joined the board of HEICO, a company
that manufactures aircraft parts, there were some problems
with management, and the board had to get intimately
involved in the details of running the company. Recalling
that experience, he says, "When a company is in trouble it
sucks up a lot of time. If you're on the board of a public
company and it's in trouble, you've just got to put in as
much time as it takes, or you've got to get someone to put
in the time. You've just got to be responsible to the
shareholders. You could, for example, identify very quickly
someone who could come in and turn things around. Or,
alternatively, it could be months and months of long-
distance phone calls for hours at a time every day."
Even if a director meets his or her responsibilities with
due diligence, in an increasingly litigious society there's
the ever-present possibility of being sued. Notes Misher,
"If you have a 15 percent drop in your share price for a day
or two, computer programs will flash that to a whole host of
plaintiff lawyers. You'll have class-action suits filed the
next day. If you are a director long enough anywhere, you
will find yourself in the middle of a class-action suit."
Almost all companies provide liability insurance to their
directors and officers to cover this contingency, but
prospective board members should ensure that this insurance
is adequate. "`Adequate' for me is usually $10 million on a
personal basis, above the resources of the company," says
Misher. "You are totally indemnified from liability in the
conduct of your responsibilities for the company. But that
indemnification doesn't hold if you can be found responsible
for illegal, inappropriate action."
In addition, board members must be careful to avoid the
appearance of a conflict of interest. In fact, Tufts'
Krimsky thinks that actual or perceived conflicts of
interest are so serious and so damaging that academic
scientists asked to join a board should just say no.
Besides the obvious quandary that occurs when a board member
is called upon to give a scientific evaluation of the work
of a company in which he or she has a stake, conflicts can
arise when a scientist directs a student to a particular
area of research that may be of interest to the firm.
Conflicts can become an issue when a scientist serves as an
expert adviser to government agencies. And they can occur
when the time a scientist spends working on company-related
business detracts from the time he or she spends on academic
pursuits.
Krimsky believes that if a scientist feels compelled to join
a corporate board, in order to satisfy ethical
considerations he or she must agree "never to take any
government-funded research projects that are directly
related to any work in the company."
Says Krimsky of the fundamental conflict of scientists
joining boards: "If our universities are filled with people
and departments who have multiple interests--not only
academic interests but also financial interests in firms--
then we simply have no reservoir of independent opinion
left. We can't get it from the companies. We're not going to
get it from the government. And therefore what we're left
with are very few places in which an expert can be
considered by the public to have an independent role in
society."
Financial Rewards
Serving as a director can be quite lucrative. Some Fortune
500 companies pay $40,000, $50,000, or even $60,000 to
directors. But smaller companies often pay much less. "The
compensation can be substantial, but it can also be zip,"
notes Misher. "I serve on one board where the compensation
is zero. I just get out-of-pocket expenses. It's a start-up
company, and I said, `Look, I'll share the risk, I'll take
some stock options. If the company succeeds, I succeed. If
the company doesn't succeed, I get nothing.' But I really
enjoy it. It's fun, it's exciting, they're doing great
things, and I have great faith in the company. I'm getting
my compensation in a variety of other ways."
Unfortunately for those scientists who would like to serve
on a board, this is not a position you can apply for. "Board
invitations are generally extended to those people who have
made some reputation somehow," says Schriesheim. "They've
gotten to be known for their technical work in a particular
field, or for their advancement in a university to
management and administrative posts, or for their government
service. But usually, in my limited experience, saying that
you'd like to be on a board and please won't someone ask me,
is a way not to be asked."
Misher advises a scientist to have two kinds of meetings
before deciding to join a board. "I would want to meet with
the chief executive officer and the operating management of
the company to assess their working relationship with the
board, their openness, their understanding of what the
board's responsibilities are, and to assess the
`chemistry,'" he says. "If the chemistry doesn't work,
forget it. This has got to be something you do less for the
compensation than for the personal enjoyment. Secondly, I
would want to meet with some outside members of the board to
get a sense of their experience. How open is that board? Is
this for show, or is it really a functional board? Does the
board have a role that it actually plays in the company's
business?"
Kriger adds that a prospective board member should consider
the soundness of the company's finances and management. "You
should be asking for substantial recent audits, but more
importantly, you should be asking directors about their
experience with the organization. What's it like to serve on
the board? Do [the directors] like it? You should get a good
feeling about the health of the organization. Are people
openly disclosing things to you, or are they being
protective? Any time your intuition is saying, `This doesn't
feel right,' you really have to honor those feelings and
follow them up."
Nonetheless, Kriger encourages scientists to become
directors. "It can be very challenging, but it's potentially
a very exciting thing to do, because you're being invited
into the inside of this organization without being a full-
time member," he says. "There's a way in which, in its
purest sense, directors function like the Solons of ancient
Greek society--the wise men overseeing the organization. It
can be a really fulfilling experience."

TI : Two Longtime Friends Share Tyler Prize For Their 30-
Year Environmental Study
AU : PHIL BECK
TY : PROFESSION (PEOPLE)
PG : 23
F. Herbert Bormann and Gene E. Likens, whose ongoing, 30-
year ecosystem study has led to fundamental discoveries that
have changed environmental law and international policy,
have received the 1993 Tyler Prize for Environmental
Achievement. The $150,000 prize, established by John and
Alice Tyler in 1973 and administered under the auspices of
the University of Southern California, was presented last
month in Los Angeles.
The Hubbard Brook Ecosystem Study, centered in the White
Mountain National Forest in New Hampshire, came about when
Bormann, an agricultural scientist, joined forces with
Likens, a zoologist, while they were both on the faculty of
Dartmouth College in the early 1960s. Together they
conceived and developed the idea of using a small watershed
to conduct whole-forest ecosystem experiments. Through
conventional scientific methods, long-term observations, and
ecological modeling, they were able to test hypotheses in
field experiments.
The pair discovered the phenomenon of acid rain (G.E.
Likens, F.H. Bormann, et al., Environment, 14[2]:33-40,
1972; G.E. Likens, F.H. Bormann, Science, 184:1176-9, 1974),
which led to the first international symposium on acid rain
and further studies on the subject throughout the United
States and Canada. Research connected with the Hubbard Brook
study played a major role in the development of the Clean
Air Act of 1990.
Another Hubbard Brook study sparked national discussion of
the effects of forest clearcutting, pointing out the loss of
soil fertility and chemical degradation of stream water
caused by this foresting method (G.E. Likens, F. H. Bormann,
Ecological Monographs, 40[1]:23-47, 1970).
"We were using the chemistry of stream water much like a
physician uses the chemistry of urine or blood . . . to
judge the health of the whole forested landscape, and that
turned out to be a very valuable way of proceeding," Likens
says.
In an investigation with colleague Kathleen C. Weathers
(K.C. Weathers, G.E. Likens, F.H. Bormann, et. al., Nature,
319:657-8, 1984), they collected and analyzed cloud water,
and showed that it was significantly more polluted than rain
water. Their conclusions demonstrated that measuring air
pollution must include cloud water inputs and dry fallout,
in addition to acid rain. Their study led to the
establishment of a North American network of cloud water
research stations.
The Hubbard Brook study, supported by the National Science
Foundation and the Forest Service, has attracted more than
125 collaborators.
Bormann left Dartmouth in 1966 to join the faculty of the
Yale University School of Forestry and Environmental
Science, where he taught until his retirement in 1992. He
remains Oastler Professor of Forest Ecology, emeritus, at
Yale. Likens went from Dartmouth to Cornell University in
1969, where he held several positions in the section of
ecology and systematics, including chairman in 1982-83. He
left Cornell in 1983 to create and direct the Institute of
Ecosystem Studies in Millbrook, N.Y.
Although their academic paths have diverged, their
collaboration has remained constant over three decades,
which Likens attributes to several factors: "We both have a
broad view of ecology, an ecosystem point of view," he says.
"I think the fact that we brought very different strengths
to bear made the team successful, and we were always able to
think and write together, which I've found to be unusual."
Bormann, 71, earned his B.S. in agricultural science from
Rutgers in 1948 and his Ph.D. in plant ecology from Duke
University in 1952. Likens, 59, received his B.S. from
Manchester College in Indiana in 1957 and his Ph.D. from the
University of Wisconsin, Madison, in 1962, both in zoology.
Likens observes that public consciousness of the environment
today is quite different from what it was when he and
Bormann began their collaboration. "In the mid- to late
'50s, if you mentioned that you were an ecologist on the
main street of any city," he says, "they wouldn't have had a
clue of what that meant. Now, of course, ecology and
ecologists have become household words."
The reason for this change, Likens notes, is not necessarily
good: "Everything you read and hear and see continues to
talk about a continuing or new environmental assault on our
living space. . . . There are new ones that crop up every
day.
"I feel very strongly that the basic research that I do I
want to have relevance to real-world problems, and I also
care a lot about trying to communicate my scientific
findings to decision-makers and the public."

OBITUARY
------------------------------------------------------------
TI : LEWIS THOMAS
TY : PROFESSION (OBITUARY)
PG : 23
Lewis Thomas, a noted biologist, physician, educator, and
medical school dean who also was well known as an award-
winning author, poet, and philosopher on science, medicine,
and other matters, died December 3 in New York of
Waldenstrom's disease, a condition resembling lymphoma. He
was 80 years old.
Thomas, who was president, emeritus, of Memorial Sloan-
Kettering Cancer Center and a professor, emeritus, at
Cornell University Medical College at the time of his death,
did research in the areas of immunology, virology,
endotoxins, and histocompatibility. He published more than
200 scientific papers.
The son of a doctor and a nurse, Thomas received his B.S.
from Princeton University in 1933 and his M.D. from Harvard
University in 1937. In the 1940s and early 1950s he held
positions in the medical schools of Harvard, Johns Hopkins
University, Tulane University, and the University of
Minnesota, as well as the United States Naval Medical
Research Unit during World War II.
He was a professor and chairman of the department of
pathology at New York University-Bellevue Medical Center
from 1954 to 1958 and was chairman of the department of
medicine from 1958 to 1966. He was dean of New York
University School of Medicine from 1966 to 1969, a professor
and chairman of the department of pathology at Yale-New
Haven Medical Center from 1969 to 1973, and dean of Yale
University School of Medicine in 1972-73. From 1973 to 1980
he was president and CEO at Memorial Sloan-Kettering; he was
chancellor there from 1980 to 1983.
In addition, he held numerous positions with other medical
schools, hospitals, foundations, societies, corporations,
and government task forces and advisory committees.
Thomas's literary career began with poems he wrote for the
Atlantic Monthly while still an intern in Boston. He first
received wide recognition for essays, originally published
in the New England Journal of Medicine, which were compiled
in the book The Lives of a Cell (New York, Viking Press,
1974), for which he won the National Book Award in 1974.
Hundreds of thousands of copies were sold, and it was
translated into 11 languages. That effort was followed by
The Medusa and the Snail (Viking, 1979), which won the
American Book Award and the Christopher Award; The Youngest
Science (Viking, 1983), his personal medical memoir; Late
Night Thoughts on Listening to Mahler's Ninth Symphony
(Viking, 1983); Et Cetera, Et Cetera: Notes of a Word
Watcher (Boston, Little, Brown, 1990), essays on language;
and The Fragile Species (New York, Charles Scribner's Sons,
1992).
He won numerous awards, including two that were named for
him, the Lewis Thomas Award for Communications from the
American College of Physicians in 1986, and the Lewis Thomas
Prize from Rockefeller University in 1990. He received 20
honorary degrees in science, laws, letters, and music. He
was a member and an officer of a host of societies,
including the National Academy of Sciences, the American
Academy and Institute of Arts and Letters, the American
Academy of Arts and Sciences, and the American Philosophical
Society.
