REALIZING ACADEMIC RESEARCH: Technology transfer between academia
and industry is expanding rapidly, partly because the two sectors
can help each other more now than ever before. Concerns in
Congress and elsewhere that academic culture will be undermined
by the increased commercial presence on campus are exaggerated,
according to researchers and technology transfer officers. (First
part of a two-part series)

SCIENCE AFTER THE FLOOD: The floods that ravaged the Midwest this
summer spared the major research institutions in the affected
states. But for some scientists--especially environmental and
agricultural researchers--whose field laboratories and areas of
study were located in the path of the raging waters, the effects
on work in progress were devastating

NEW SEMESTER, SAME SAD STORY: On college campuses around the
United States, the school year is beginning with little relief
for researchers from continued cuts in government funding,
punctuated by an increasing need to comply with health-and-
safety, cost-accounting, and other federal regulations that
further consume time and resources. The situation has caused some
scientists to leave academia altogether, but those who remain say
they will muddle through

A CALL FOR REFORM: Penn State physicist Rustum Roy expresses his
belief that news of scientific advances should reach a wide

TI : Technology Transfer Boom Offers Scientists Rewards--And
Challenges
As industry-academia deals proliferate, scientists on campus must
also negotiate conflicts that arise
AU : FRANKLIN HOKE
TY : NEWS
PG : 1
***
Editor's Note: In this first part of a two-part series, academic
researchers and university officials involved in technology
transfer discuss its beneficial effects on academic science and
society. In the second part, to appear in the Sept. 20, 1993,
issue, scientists and others express concern that increasing
emphasis on corporate-supported research may significantly
undermine aspects of basic science on campus.
***
A boom in technology transfer activity is under way on the ill-
charted ground upon which academic and industry science interests
overlap. Becoming dramatically visible in the 1980s--on the heels
of pivotal new intellectual property law--and continuing into
this decade, the increased cooperation is bringing important
changes to both sectors, say researchers and technology transfer
officers.
This growth in the conversion of basic research findings into
marketable products or services is bringing welcome new resources
into academic labs and allowing researchers to see their ideas
carried through to realization, observers say. And the infusion
of basic research ideas into company labs is surely stimulating
the development of new products.
Muting, somewhat, this growing enthusiasm for academic-corporate
collaborations are traditional concerns of academicians that an
increased commercial presence on campus may undermine important
elements in their culture--support for unfettered, curiosity-
driven work, for example. More crucial to many are the questions
that arise concerning conflict of interest: When a scientist's
work is simultaneously supported by a university and a private
corporation, where do his or her interests properly lie? And if
there are choices to be made in terms of investing time and
intellectual energy, which funder comes first?
Faculty and administrators involved in technology transfer say
they have worked to confront these difficult issues directly and
that such worries are exaggerated.
"An increased presence of any kind of major [social] institution
on campuses carries with it advantages and risks," says David
Kipnis, Distinguished University Professor of Medicine at
Washington University, St. Louis. Kipnis, a diabetes researcher,
also chairs the committee overseeing the joint biomedical
research program between the university and the Monsanto Co.,
also located in St. Louis.
"For example," he says, "you could just as well substitute
government for industry. Too much government on campuses has
created problems, where major [agencies] attempt to overdirect
and micromanage research. The same thing could be true if
industrial intrusion becomes excessive. Academic institutions
have to always be on the lookout. We should relate with all, but
make certain that our primary roles in society are not unduly
influenced or subverted by these relationships."
Advocates for increased corporate involvement in basic science
say that funding constraints in the federal government--in
particular at the National Institutes of Health--necessitate such
new approaches to supporting science. And they see no threat in
well-managed relationships between academic labs and companies.
"As the NIH budget continues to effectively shrink, there are
going to have to be alternative ways to support research, and
we're going to have to find mechanisms to achieve that," says
Anthony Cerami, president of the Picower Institute for Medical
Research, Manhasset, N.Y. "And, in my mind, the most creative
research can be done in academic institutions or research
institutes, away from industry, because they don't have the
quarter-to-quarter pressures that a company would have, and so
they can really do things that are imaginative."
Before launching the Picower in late 1991, Cerami headed a lab at
Rockefeller University in New York where an antibody potentially
able to block the damaging actions of a cytokine called tumor
necrosis factor, or TNF, was discovered (F. Hoke, The Scientist,
Feb. 22, 1993, page 1). Patents based on the findings were
initially licensed to Chiron Corp., Emeryville, Calif., for
development and then to the United States subsidiary of Bayer AG,
Leverkusen-Bayerwerk, Germany. Cerami has collaborated with
company scientists throughout the preclinical process, and a
therapeutic product is now in late-stage clinical studies.
"I don't really view getting support from a company any
differently than getting support from [funders like] the NIH,"
says Cerami. "They have their objectives, and companies have
theirs."
Many scientists also say a prime motive for working with
companies is the strong personal satisfaction they derive from
seeing useful applications developed that are based on their
research ideas. They recognize, too, the necessity of
contributing to that process to ensure its success.
"You can have a great idea, but if it doesn't end up helping
people, then it's not so rewarding," says Helen M. Blau, a
professor of molecular pharmacology at Stanford University's
School of Medicine. "The technology transfer process helps you
have that chance. For example, I'm not going to be able to, in my
lab, grow cells under the quality control and in the quantities
necessary for a clinical trial. So, if there weren't companies to
pick up the technology and move it to the next step, it might not
get there."
Blau's research at Stanford found that myoblasts (muscle cells)
could be useful in gene therapy to deliver recombinant proteins
in the treatment of muscle disorders and other maladies like
growth hormone deficiency. She is working with the biotechnology
company Cell Genesys, Foster City, Calif., to develop specific
applications of these findings.
"It's truly exciting to be part of this process," Blau says. "And
if I'm not consulted and a part of it, then it's less likely to
happen."
But despite increasing interactions, academic researchers are by
no means unanimous in embracing industry support, which can be
accompanied by over-specific direction and, often, little
scientific return.
"I have been reluctant over the years to take on projects that I
call `hybridomas for hire,' " says Alexander Karu, a professor of
biochemistry at the University of California, Berkeley. "One of
my concerns has been the heavy unidirectionality of the
information flow [in relationships with industry]. People who've
approached me want to know a great deal about our plans and what
we're doing, but we get very little feedback in terms of basic
science. And my mission here is basic science."
Despite these misgivings, Karu is currently developing a series
of antibodies with a major chemical company, in what he
characterizes as a true two-way collaboration. The company's
synthetic organic chemistry expertise has complemented his own
lab's capabilities very well, he says.
Finding Homes For Technology
University technology officers cite changes during the 1980s in
the laws governing intellectual property to explain the
continuing expansion of technology transfer activities. Probably
the most important of these is the 1980 Bayh-Dole Act, or Public
Law 96-517, which allowed universities for the first time to
patent inventions based on federally funded work at their
institutions.
By the end of the decade, hundreds of institutions had opened
patents and licensing offices to facilitate the transfer of
their researchers' findings to companies where useful
applications might be developed--and royalties generated. Growth
in the numbers of new technology transfer offices continues to be
strong.
Among the institutions leading the way and providing important
guidelines for others have been Stanford, the Massachusetts
Institute of Technology, and Harvard University.
The increased royalty income derived from licensing is an
important new source of university research support, university
technology officers say. But they also insist that placing
research findings where they can best be developed into
beneficial products is perhaps an even more important goal of the
process.
"This is kind of like finding homes for a lot of different
technologies," says Katharine Ku, director of Stanford's Office
of Technology Licensing. "The family that wants a child is the
one that, at least theoretically, might be the best family. So,
when we try to find a licensee, a company that's interested in
devoting the resources [to development], the best licensee is the
one that cares the most. Our biggest fear is that the licensee
takes the license and just sits on it."
Clear patent ownership by the universities has been crucial in
generating company interest in investing in academic research,
too, according to technology transfer officers and researchers.
"Before that time, it was very difficult for a company to be
assured that it could get an exclusive license to a patent that
came out of research it sponsored on campus," says Duke Leahey,
director of industrial contracts and licensing at Washington
University. Leahey is also president of the Association of
University Technology Managers.
"You're not going to invest eight to 10 years and millions of
dollars taking a product from its bench-type invention through
definition of the product, clinical trials, and FDA [Food and
Drug Administration] approval, to then hope the consumer buys it,
unless you have some sort of proprietary position," says William
Hoskins, director of the Office of Technology Licensing at UC-
Berkeley. "The patent provides that, and an exclusive license to
that patent goes even further."
"Companies are really the only group with the financial and
personnel resources to develop diagnostics and therapeutics,"
says Cerami. "And without patent protection, it makes it almost
impossible for a company to be able to justify spending the very
large amounts of money it takes to develop an idea into a viable
product."
Researchers also say that, besides managing university
intellectual property, campus technology offices provide another
vital service. In today's complex legal atmosphere, investigators
who use a given firm's reagents, for example, may find that
company later laying excessive claim to their research results.
University technology offices have the expertise to help
scientists steer clear of such ensnarement, while still being
able to take advantage of important tools and collaborations.
"We have been working in the area of recombinant antibodies,"
says Karu, "and we wanted to license some of the vectors from the
Scripps Research Institute [in La Jolla, Calif.]." Berkeley's
technology officer, Karu says, "was very instrumental in
negotiating rational arrangements by which we could use those
vectors. So, [the technology office] helps in this way, when I
have a question about using somebody else's reagents or materials
without becoming a de facto employee or having any claim placed
upon my work by the donor."
"Sometimes, when companies give you reagents, they want you to
sign all kinds of forms," says Stanford's Blau. "Every time I get
a reagent from someone, I run the forms through the technology
office here, to make sure that whatever I'm signing does not in
any way interfere with my function as a professor, that I can
speak and publish freely. So, the office here helps protect us."
Peer-Reviewing Conflict
The potential for conflicts of interest that concerns people
inside and outside academia go beyond the worry that a researcher
may redirect his or her research to attract more funding or to
benefit a company in which the researcher may have a financial
interest. They also extend to conflicts of commitment--basically,
failing to reserve enough time to properly discharge university
duties, such as teaching--and to exploitation of graduate
students.
Because the whole arena of technology transfer is complicated and
relatively unexplored, say technology officers and researchers,
guidelines for conduct are only just emerging on many campuses.
"Universities have developed their policies in response to
situations that they've been presented with," says Jim Severson,
assistant director of the Office of Patents and Licensing of the
University of Minnesota, Minneapolis. "Ten years ago, we couldn't
have envisioned the different kinds of involvements possible."
Among the most flexible and effective tools that the universities
have for dealing with conflicts, they say, are disclosure and
peer review. These tactics have the added advantage of tending to
involve the wider community in considering these difficult
issues.
In most cases, researchers make disclosures to their departmental
chairperson for review. On a number of campuses, faculty
committees are asked to monitor individual relationships. When
disputes do arise, enforcement authority often resides in a dean
or other administration official.
"We feel the essential first step is to have total and complete
disclosure," says Stephen Sammut, managing director of the Center
for Technology Transfer at the University of Pennsylvania in
Philadelphia. "And then we review the cases and try to manage the
conflicts of interest."
The need to develop mechanisms to confront potential conflicts is
seen as a high priority where technology transfer is active.
"Given the complexity of commerce and academe these days," Sammut
says, "if we simply put on blindfolds and made believe conflicts
of interest are not going to happen, we would, number one, be
fooling ourselves and, secondly, not really serving the public
interest."
"You shouldn't be left to your own devices when money is
involved," says Washington University's Leahey. "So, you should
have a conflict of interest policy and a committee that reviews
things for people to remind them when they're getting a little
far afield."
Leahey says, too, that while the NIH and the National Science
Foundation are both struggling to develop conflict of interest
policies for their grantees (NIH must publish its effort by early
December this year, by congressional mandate), enforcement of
those policies should remain the responsibility of the individual
institution.
At Washington University, officials have gone further and
organized an external review committee to periodically assess the
university's relationship with the Monsanto Co. According to
David Kipnis, all reviewers are members of the National Academy
of Sciences; molecular geneticist Daniel Nathans, a 1978 Nobel
Prize winner in physiology or medicine and a former Washington
University graduate now at the Johns Hopkins University School of
Medicine in Baltimore, is chairman of the committee.
According to Kipnis, one of the most important concerns for their
review committee is the potential misuse of graduate students.
"[Review committee members] meet with graduate students, with
post-doctoral fellows," he says, "to make sure that the
arrangement has not distorted their research."
Christina Jansen, a licensing officer at MIT, says students are
also carefully protected at her institution.
"Graduate students can end up working on projects for outside
companies instead of doing their thesis research," Jansen says.
"Activities detrimental to the academic teaching mission is one
problem we watch out for."
And at UC-Berkeley, the faculty conflict of interest committee is
also sensitive to this issue.
"What they're really trying to protect," says technology officer
Hoskins, "is the relationship between the student and the faculty
member, because the student is in a vulnerable position, working
for the faculty member and also trying to pursue an advanced
degree. And if the faculty member has an outside interest in a
company, he could be using cheap labor for his own particular
benefit."
While they do take conflict-of-interest issues seriously, many
researchers say that pressures to skew the aims of research or to
lie about the results are not new in science nor unique to
university-industry relationships. They also say that the issue
of conflicts does not pose a larger threat to academic culture,
as some fear.
In fact, some scientists say that, rather than undermining
academia, technology transfer allows basic scientists who want to
see applications result from their work to see this happen while
remaining focused themselves on fundamental research.
"We need that kind of dialogue, that interchange, that flow of
information from the basic scientists to industry to the clinic,"
says Stanford's Blau, "without people having to leave academia
because they want to see their ideas developed and applied toward
treating human disease."
Blau adds that letting companies take on development tasks can
free the academic researcher to return to basic investigation.
"The things that I give to companies to do are things I can't or
don't want to do here," she says.
Some researchers also see fundamental differences in outlook
between the goals of business and of academic scientists that
will tend to preserve the distinctions between industry and
academia.
Biologist Steve Roth's experience suggests this might be the
case. Roth is a former chairman of the biology department at the
University of Pennsylvania, currently on leave from the
university. For now, he is vice president of research and
development and chief scientific officer of Neose Pharmaceuticals
Inc., Horsham, Pa., a startup aimed at developing the drug
therapy potential of his more than two decades of university-
based research into oligosaccharides.
In another year, the university has told Roth, he will have to
decide whether to relinquish his university position or to leave
behind Neose, a business founded on the pursuit--albeit the
product-oriented pursuit--of his scientific ideas. Despite this,
and the fact that the size of the project at Neose is roughly 20
times the size of his academic lab at Penn, the choice will not
be easy, he says.
"I'm a biologist, and that's what I've been my whole life," says
Roth. "I'm mystified by how living things are organized. It's in
the core of my research."
And wherever you go in the university, he says, you run into
people who are similarly motivated.
"In the business world," he says, "you deal all day long with
people who really worry only about money. And that's not in any
way derogatory--these are super-intelligent, dead-honest people.
But their overriding concerns are not why a maple leaf is
different from an oak leaf, for example, or why a pigeon can tell
the difference. For someone who's spent his entire life with the
former kind of person, it's a little odd."

TI : Academic Scientists Launch Into 1993-94 School Year With
Little Hope Of Easing Serious Funding Problems
While years of working under burdensome fiscal constraints have
yielded strategies for coping, a gloomy mood persists
AU : BARBARA SPECTOR
TY : NEWS
PG : 1
On campuses across the United States, academic scientists and
research administrators are beginning the 1993-94 school year
with no expectations of relief from the fiscal and regulatory
difficulties that have marked the past several autumns. States
continue to cut back on support for public and private colleges
and universities; moreover, the pool of federal funding is not
growing sufficiently to keep up with the increased numbers of
scientists vying for grants to support their research.
"There's a level of acceptance on our campuses" that the funding
situation is not going to improve, says Cornelius Pings,
president of the Association of American Universities (AAU).
To make matters worse, research administrators say, the paperwork
required to satisfy government safety, cost-accounting, and
animal-care regulations is mushrooming. At the same time, stiffer
indirect-costs restrictions prohibit schools from receiving
government reimbursement for the hours spent on such time-
consuming labor.
"It's a catch between a rock and a hard place," says Earl Friese,
a materials scientist who is director of sponsored research at
the California Institute of Technology. "We're required to do
more administration--which costs more --but the government says,
`We're not going to pay for it.'<|>"
The much-publicized 1991 investigation into accusations that
Stanford University misused millions of dollars in federal funds
has changed the way university research is regarded by Congress,
says Suzanne Polmar, a biologist who is director of grant and
contract administration at Yale University. "Since the Stanford
mess, there's been a change in the whole culture in which
universities deal with the federal government," she says. "We
started as a joint, cooperative enterprise." But in recent years,
she notes, universities have been viewed by the government "less
and less as collaborators in the research effort. We're now
viewed in the same way as defense contractors," with memories of
egregious overcharging for hammers and toilets still fresh in the
public consciousness.
"The nature of the relationship has to be rejustified," says
Milton Goldberg, executive director of the Council on
Governmental Relations (COGR), a Washington, D.C.-based lobbying
group representing 130 research universities. "What is the
usefulness--the value to society--of fundamental research? Most
of the people who understand that have passed from the scene.
People are now questioning more than ever before this fundamental
relationship." Exacerbating the problem for those in fields like
physics, he says, is that "also passed from the scene is the Cold
War and the idea that we [conduct research] in the name of
defense."
"There's a lot of anxiety among scientists," says Marilyn Gist
Farquhar, coordinator of the division of cellular and molecular
medicine at the University of California, San Diego. "There's no
such thing as being relaxed about a grant [application] that's
under review, no matter what you've done. The competition to
obtain money and resources is so high, and it takes so much time,
that it off-balances other things." Thus, she says, scientists
have less time to fulfill their obligations to the scientific
community, such as teaching or serving on committees.
A ray of hope on the gloomy horizon, however, is that, after
several years of working under budgetary and regulatory
constraints, scientists and administrators say they are
developing strategies to deal with them. While the mood at many
universities is still dismal, prompting some researchers to leave
academic science altogether, those who remain say they are
creating ways to muddle through.
As the era of austerity lingers on, "it gets less frustrating,
[although] it doesn't get any easier," says Nina Matheny Roscher,
chairwoman of the chemistry department at American University in
Washington, D.C. "You get used to what the limitations are."
Reviewing And Regrouping
Many schools have found that the best way to cope with the crunch
is to evaluate all their research programs, emphasizing the ones
that are found to excel and dropping the rest. Two years ago,
schools were gradually coming to the conclusion that they ought
to concentrate resources on a few strong programs rather than
spread them among many investigations of varying quality (R.
Eisner, The Scientist, Sept. 2, 1991, page 1). Today, "almost all
are doing some sort of evaluation, possibly with an eye to
trimming the enterprise," says Pings of AAU's member
universities.
"It's an era of some restraint and adjustment," Pings says.
"There's a sense that we're all in it--we all have to think out
our role, decide what our niche is, and forgo some areas."
Yale's Polmar speculates that eventually, schools will realize
that it is no longer feasible to fund whole research programs
almost exclusively through grant money. "Medical schools have
been funding entire divisions on soft money," she says. "If [a
program is] important to a university, then the university will
have to be prepared to fund it in some way." For example, she
says, "should the government be paying 90 percent of faculty
salaries? That level of expenditure uses up resources, and I
don't believe the supply of funding is going to grow any bigger."
A positive consequence of reevaluation might be a renewed
emphasis on teaching, says Robert Smith, a pharmaceutical chemist
who is vice provost for research and dean of the graduate school
at Washington State University in Pullman. "To keep within
budget, [schools] have to consider different priorities for the
faculty," Smith says. This is already happening on some campuses,
including his own, he says: "I see a real shifting of emphasis in
our own institution--[to a new] emphasis on teaching excellence."
At Washington State, documentation of a faculty member's teaching
efforts and teaching evaluations are used "as part of the
portfolio [assessed in the decision-making process] for promotion
and tenure."
The Quest For Funds
Science faculty are not the only ones whose jobs are being
redefined in these cash-strapped times; academic administrators
say that fund raising is becoming a bigger part of their
responsibilities. American University's Roscher says she spends
about 15 percent of her time in pursuit of research support from
private donors and other sources: "It's spending more time than I
ever thought I would spend."
One way she has found to offset costs, Roscher says, is to locate
government labs near her District of Columbia campus willing to
share their equipment with students. "We can't possibly keep up
with the latest equipment, because it's changing too fast," she
says. "But the government labs are very helpful to the scientific
community. If an instrument is available at night or on weekends,
they try to accommodate us."
A funding challenge that has been particularly nettlesome is
finding money to cover graduate student stipends. "We have
increased costs for graduate student stipends because of cutbacks
in state funding, at the same time as tuition is going up," says
Washington State's Smith, noting that over the past three to five
years tuition at his school has doubled, to $15,000. "This puts
added pressure on grants," the usual source of funds for
stipends, he says. "The faculty are saying, `I don't know how I
can afford to have grad students.' That's another tension that's
out there." Compounding the anxiety is a recent news report that
the National Institutes of Health is considering limiting its
training grants for grad students to 70 percent of tuition.
Currently, NIH reimburses universities for anywhere from 65
percent to 95 percent of a student's tuition (Science, 261:415,
1993).
Roscher says she seeks out private donors willing to support
students. Other sources of help, she says, are cooperative
education programs or summer internships in which students work
full-time and receive a salary. "While it delays their
graduation, it can provide substantial money for a short period
of time," she says. Because such experiences generally offer the
opportunity for students to be exposed to new equipment, she
adds, they are a source of educational value as well as fiscal
relief.
New Avenues
Of course, academic scientists bear the brunt of the burden in
the quest for dollars to fund their programs, and, with federal
funding sources drying up, they are increasingly turning to
private foundations and to industry for support. "Investigators
are becoming more active in terms of the number of proposals they
submit per faculty member," says Caltech research administrator
Friese. "We're seeing a higher volume of proposals going through
for the same amount of dollars. People are trying harder and
harder."
"We have seen an increase in the number of awards--but the
dollars haven't gone up," says Yale's Polmar.
"Faculty need more grants to get the money necessary to do one
project. That takes a lot of work on the part of a PI [principal
investigator]--time that could be spent in a lab. They tend to
get resentful about that."
To ease the pressure on the researchers, Polmar says, the grants
and contracts office at Yale--itself short-staffed, and
struggling to keep up with the flow of applications--has been
picking up some of the detail involved in grantsmanship. "We try
to keep the stuff that [faculty] have to do for us to a minimum.
We're doing more and more with less and less; we're trying to
computerize as much as possible."
Fred King, director of the Yerkes Regional Primate Research
Center at Emory University in Atlanta, says his staff is seeking
outside help in coping with the flood of paperwork required for
grant applications as well as to comply with health-and-safety,
animal-care, and other government regulations. "We've brought in
people to design systems for processing applications and
information in order to streamline the paperwork and the
meetings, but make sure we still do a responsible job" of
following the rules, he says. "Scientists may not be the people
who are best at designing those systems, although you need to
have scientists involved, of course."
Forming Partnerships
As it becomes more obvious that there will not be enough federal
funds to go around, industry is increasingly being looked upon by
university faculty and administrators as a potential sponsor of
research. But recent controversy over a 10-year, $300 million
deal between the Scripps Research Institute of La Jolla, Calif.,
and the Swiss giant Sandoz Pharmaceuticals Corp. has made many
academic administrators nervous about such alliances. After
Congress and NIH loudly voiced concerns over the propriety of a
foreign company's taking control of research from a federally
funded institution, the Scripps-Sandoz contract was renegotiated
in June (C. Anderson, Science, 260:1872-3, 1993).
"Universities for years have been advised to seek external
funding sources, to bring in more industry dollars" to substitute
for scarce federal support, says Ann Stevens, a biochemist who is
associate vice president for research at Emory. "Now, we're being
criticized because we might have entered into deals that were
questionable. But, by and large, universities have been very
careful about negotiating limited conditions for licensing
technologies developed under research agreements."
"We've increased the number of [corporate] contracts, as opposed
to grants from NIH or the National Science Foundation, over the
past three or four years greatly," says Yerkes' King. The center
director says he is spending more time "generating new ideas,
[determining] how we are going to work with industry."
King stresses that "strategies do need to be developed" to ensure
that university-industry ties produce "corporate contracts that
are also good-quality science. There has to be a payoff for
scientists, too. You have to be doing quality science, not just
working for a company on a contract basis." If contracts aren't
carefully negotiated to allow re- searchers the freedom they
need, he cautions, "you can degrade your science doing something
that just gets the job done for somebody."
Another way for academic scientists to cope under stressed
funding conditions, says UC-San Diego's Farquhar, is to
collaborate with each other. NIH, for example, offers program
project grants, given to a group of researchers who "pool their
expertise," says Farquhar, who has received such a grant along
with eight colleagues from UC-San Diego and Scripps who are
teaming up to investigate the role of GTP binding proteins in
membrane trafficking and cell proliferation.
"I'm a great believer in collaborative research," she says. While
the money crunch has made cooperative research more common than
it was 10 years ago, Farquhar points out, collaboration makes
sense from a scientific perspective as well as a fiscal one.
"Most problems require a multidisciplinary approach, and in
universities, everyone can find people with a common problem
interest and complementary expertise," she says. "We can't all be
right at the forefront in six or seven different approaches."
Joining with others who can approach the project from varying
perspectives, Farquhar says, enables a scientist to "get further
faster than you can working alone."
Bailing Out
Yet some academic scientists are fed up with the challenge of
seeking new forms of funding; many are throwing in the towel and
leaving their research careers behind. "There's still a lot of
pessimism around," says Farquhar. "The most pessimistic have now
gone in different directions."
Some biomedical scientists with M.D. degrees, she says, are
opting to "get out of research and turn their attention to
clinical practice because they have that option." Others are
leaving academia to take jobs in industry, particularly at
biotech and pharmaceutical companies. Some who wish to stay on
campus might decide to abandon their research and go into
administration.
But seasoned observers of the quest for government funding say
there is no cause for despair; scientists should just relax and
be prepared to change with the times. "Folks are just going to
have to do less research," says COGR's Goldberg. "It's a
practical impossibility to do more work with less resources.
Modern research is very capital-intensive, and it requires a good
deal of investment.
"But I wouldn't view that in a pessimistic way," Goldberg says.
"There's a fair amount of money available to do a lot of things.
Those who are competing in [the federal funding environment] are
still going to be doing a lot of good work."

TI : In Wake Of Summer's Ruinous Floods, Scientists Assess Toll
On Research
Institutions in the stricken states were spared, but individual
researchers report significant setbacks
AU : SUZANNE HAGAN
TY : NEWS
PG : 1
As the householders and businesspeople of the central United
States try to dry out and put their lives back together following
the Great Flood of 1993, an informal survey of Midwest research
institutions indicates that, in general, scientists emerged
relatively unscathed by the disaster.
As fate--and maybe even a certain amount of intelligent advance
planning--would have it, no major academic or industry science
center in Minnesota, Iowa, Kansas, Missouri, or other beswamped
states suffered signifi- cant damage or interruption of research
activities. For the most part, their research facilities are
located safely inland from the banks of the Mississippi,
Missouri, Kansas, and Des Moines rivers, the waterways whose
relentless midsummer overflow caused a tragic loss of human lives
and property.
That scientists in general escaped trauma and destruction,
however, is not to say that all researchers and scientific
endeavors were spared. Agricultural scientists, for example, for
whom the fertile Mississippi floodplains are prime growing sites-
-and, therefore, their laboratories--saw their workplaces
disappear under a sea of rushing mud, as did wetlands ecologists
working for government agencies such as the U.S. Fish and
Wildlife Bureau.
At press time, authorities were estimating that more than 1
million acres were put under water in this deluge; at least
35,000 homes were destroyed; and at least $10 billion in damage
was done to property and crops. Anecdotal evidence, like that
offered by Nader G. Vakili, a plant pathologist and U.S.
Department of Agriculture researcher in Ames, Iowa, reveals the
range of setbacks suffered by scientists in the tragic flood.
Contacted by The Scientist for an interview, Vakili had just
finished photographing a field where three years of his research-
-half of what he'd hoped to accomplish in a five-year study of
no-till farming--had been washed away by water from the Snake
River.
Vakili, an associate professor of plant physiology at Iowa State
University, says that he plans on using the field again; but, to
be on the safe side, he may add a second location next year,
although this will increase his costs substantially.
Farther south, along the Missouri River, soybean breeder Phil
Owen, a research associate in the agronomy department of the
School of Agriculture at the University of Missouri in Columbia,
saw three of his planting sites along the Missouri River wiped
out. He's feeling somewhat more fortunate than Vakili, however,
because he has four additional sites for his studies of soybean
strains under cultivation, and he can still extract meaningful
data from them.
Owen tests soybeans for traits such as productivity and nematode
resistance. Nematode-infested sites, he points out, are
especially abundant in the floodplains. He expects a busy winter
in the greenhouse and anticipates expanded field testing next
summer to make up for his lost work this year. He also may try to
plant more sites away from the river bottoms next year, "just in
case."
Studying Survivors
For psychologist Elizabeth Smith, an associate professor of
psychiatry at Washington University in St. Louis, the flood
provided solid material for the next phase of her research. As
experts in the study of disaster victims, Smith and her colleague
Carol North, an assistant professor of psychiatry, are currently
in the process of determining which flooded areas' survivors they
will survey in a study funded by the National Institute of Mental
Health.
This $980,000 grant, awarded in 1988, allows Smith to investigate
the human aftermath of a variety of disasters, natural and
otherwise. Smith assesses survivors' immediate responses, then
charts the course of their recovery over time by interviewing
them at one-year and three-year intervals following the event. To
date, Smith has used this grant to interview survivors of a fire
and three mass shootings. The initial studies examining flood
survivors will be the last set of data collected under the
funding provided by the grant.
In addition to planning her new study, Smith has responded to the
Red Cross' call for professionals to provide counseling services
to flood victims. Smith expects to find most flood survivors
suffering from anger, depression, and anxiety: "This flood will
be much more devastating than others because many people won't be
able to clean up and return; their homes have been destroyed.
Many children have lost their summer vacations, their homes, and,
in some cases, their schools."
Among other scientists whose work was interrupted by the flooding
was a group of AIDS vaccine researchers in a clinic at St. Louis
University--a school, incidentally, that is far from the
Mississippi River's banks. The researchers depend for their
experimental vaccine studies on a regular turnout of uninfected,
low-risk, heterosexual volunteers who are willing to come in for
14 or so visits over the course of a year and a half. Most
volunteers, who normally arrive at the clinic at the rate of 10
to 12 a week, are women between the ages of 18 and 45. In early
July, the volunteers suddenly stopped coming to the clinic.
Clinic nurse coordinator Heidi Israel can't pinpoint the
correlation between the flood and the loss of the volunteers. But
she feels that their disappearance reflects how overwhelmed St.
Louisans have come to feel: "Around Fourth of July," notes
Israel, "people started sandbagging and focused on helping flood
victims." They just didn't have the time or state of mind for
anything but the immediate emergency. At press time, the
volunteers still hadn't returned, and Israel says that she
doesn't expect the situation to change for some time.
Different Perspective
Meanwhile, Washington University biology professor Owen J. Sexton
can't get within miles of the marsh in St. Charles County, near
the junction of the Missouri and Mississippi rivers, where he
studies snake populations. Although he describes these snake
species as well adapted to flooding, he expects that many of them
will be wiped out, at least temporarily.
By sheer luck, Sexton had just finished his most recent study a
few weeks before the flood. Nevertheless, Sexton's view of the
disaster is much the same as other scientists interviewed for
this story--it was an unfortunate but useful learning experience.
He regards this flood, one of four major deluges to strike the
marsh within the last 40 years, as "a big opportunity to see
how fast these populations bounce back after catastrophe."
Sexton hopes that the Missouri Department of Conservation will
allow him to continue his work at the marsh, which would be the
first recovery study there, "maybe the first for a lot of
places."
Although most measurements of the flood's impact focus on loss, a
different perspective is needed, says agricultural economist
Steven J. Taff of the University of Minnesota: "The more
interesting question is, what can we learn from the flood, not
what have we lost from it."

TI : Women Astronomers Press Manifesto For Equal Rights
AU : RON KAUFMAN
TY : NEWS
PG : 3
A coalition of more than 200 women astronomers appears to be
making headway in an effort to promote equal rights for women not
only in astronomy, but also in all scientific disciplines.
This past June, the informal group issued an equal rights
proclamation on behalf of their cause at a meeting of the
American Astronomical Society held in Berkeley, Calif. Called the
Baltimore Charter because of the site of initial discussion that
created it, the document calls for a new dedication within the
astronomy departments of research universities and other
institutions to dismantle barriers to advancement and to change
working conditions that impede the increase of women in the field
(see box on page 22).
Already, the charter has received the endorsement of the
Association of Universities for Research in Astronomy (AURA), a
consortium of 22 universities based in Washington, D.C., that
operates a number of observatories in the United States,
including the Kitt Peak National Observatory near Tucson, Ariz.
The document's authors say that within the next year, they hope
the American Astronomical Society (AAS), the National Aeronautics
and Space Administration (NASA), and the National Science
Foundation will also deliver endorsements for the sentiments
expressed in the document.
"Women should not have to be clones of male astronomers in order
to participate in the mainstream of astronomical research," the
charter states. "Women want and deserve the same opportunity as
their male colleagues to achieve excellence in astronomy."
"The advancement of women in science is an integral part of our
profession," says C. Megan Urry, chief of research support at the
Space Telescope Science Institute (STScI) in Baltimore and one of
the authors of the charter.
STScI was the location of a meeting called "Women in Astronomy"
last September, during which the impetus for creating the charter
began. Urry and coworkers at STScI organized the conference,
which attracted more than 220 participants, who took part in a
session outlining the issues, ideas, and recommendations that
form the basis for the document. Urry, STScI astronomer Laura
Danly, STScI associate director Ethan Schreier, and educational
consultant Sheila Tobias condensed the session's discussions into
the final Baltimore Charter.
The two-page manifesto points to specific problems encountered by
women in the field, such as "sexual stereotyping, opportunity and
pay differentials, inappropriate time limits on advancement,
overcritical scrutiny, and sexual harassment." It also notes,
more generally, that "unequal treatment of women in the
laboratory, the lecture hall, and the observatory, more subtle
but at least as important as overt discrimination, creates a
chilly climate which discourages and distresses women, alienates
them from the field, and ultimately damages the profession."
The charter recommends the implementation of or greater
commitment to:
* Several affirmative-action measures, including advance
publication of standards for candidates in hiring, committees,
and awards, and the elimination of cultural bias in such
standards; more women participating in the selection process in
these areas; and candidate pools that reflect the proportion of
women in the field and adjust for underrepresentation of women.
* Broadened criteria for hiring, assignment, promotion, and
awards that recognize domestic concerns, such as child rearing,
dual-career families, and reentry into the workplace.
* Strong action to end sexual harassment, including substantial
penalties for perpetrators, education and awareness programs, and
the hiring or appointing of more women to receive complaints and
participate in the review process.
* Gender-neutral language and illustrations, especially in
presenting astronomy to prospective students and the public.
Urry says it would be irresponsible for any scientific discipline
to ignore the plight of women. "Though we wrote the charter
specifically for astronomy, the whole idea is very general," she
explains. "We are hoping that other disciplines can take this as
a starting point for their own efforts to promote women in
science."
She says the issues of women in professional life are much
greater areas of concern in the 1990s than ever before. However,
Urry says, research universities are usually very slow in
changing attitudes and procedures to become more sensitive to
women's issues.
"What you have in many institutions is a group of intelligent,
competent, talented, white men," Urry says. "A small number are
quite enlightened. A small number are pretty darn prejudiced and
not about to change. But the vast majority of men have the right
thoughts, but really aren't motivated to change.
"One of the things we have to accomplish with the charter is to
persuade people that it is in their advantage, and the advantage
of science, to change."
The gradually decreasing number of women entering astronomy is
directly related to the small number of women in tenured faculty
positions, says STScI's Schreier. According to statistics he
compiled, 23 percent of graduate students in astronomy are women.
The number then drops to 17 percent of postdoctoral researchers.
And among full professors, only 5 percent are women.
Schreier's theory is that the problem of underrepresentation is a
self-perpetuating one--that without tenured faculty, younger
women are discouraged from trying to advance in the field. "Women
are not getting enough guidance," he says. "With the number of
tenured women faculty being so small, where would a grad student
look for a role model?"
High-energy particle physicist Vera Kistiakowsky, a professor of
physics and astrophysics at the Massachusetts Institute of
Technology, says that university appointments are usually made on
purely subjective grounds, and therefore women are often left
out.
"Appointments and promotions are made on the basis of merit,"
says Kistiakowsky. "I've sat on enough committees to know that
perception of merit is intrinsically subjective . . . and it
is a male model against which all these scientists are being
measured." She says the Baltimore Charter is a professional, non-
radical way of saying that reservations based on an applicant's
sex should be placed aside.
France Cordova, chairwoman of the astronomy department at Penn
State University, attended the STScI meeting last year. She says
that, along with the creation of the document itself, having
meetings that raise issues of sexual equality is important to
finding solutions.
"The problems are very big and very deep," Cordova says. "You
don't just change a lot of history and behavior with a piece of
paper like that. I don't think this charter is a giant leap, but
it will help in moving the whole effort forward."
However, Claude Canizares, the director of the Center for Space
Research at MIT, who also attended the meeting, says that he
hopes the Baltimore Charter will have a significant impact on the
field. He says that astronomy, and many of the other physical
sciences, must actively halt the exodus of women from the field.
"I think this is an important milestone along the way," he says
of the charter. "One of the things I realized more than ever was
that the real emphasis for change has to come from the men who
are already in positions of power. The fraction of tenured women
faculty is still quite small. I think it's going to take a
reasonable amount of activism on the part of men to help effect
the necessary changes."

THE BALTIMORE CHARTER'S PREAMBLE
We hold as fundamental that:
* Women and men are equally capable of doing excellent science.
* Diversity contributes to excellence in science.
* Current recruitment, training, evaluation, and award systems
often prevent the equal participation of women.
* Discriminatory mechanisms are unlikely to change by themselves.
Both thought and action are necessary to ensure equal
participation for all.
* Increasing the number of women in astronomy will improve the
professional environment, and improving the environment will
increase the number of women.

Faculty in Yale University's computer science department were
greeted with a message from a familiar name on their E-mail early
last month. Computer science professor David Gelernter, the
victim of mail-bomb attack on June 24 (C. O'Kane, The Scientist,
Aug. 23, 1993, page 1), was back at the keyboard. His cheery
message--Gelernter jokingly referred to himself as "the
department's very own official terrorist bomb victim"--was
interspersed with information indicating the seriousness of the
wounds he suffered. He wrote that he will need surgery to recover
some degree of functionality in his right hand and hearing in his
right ear. In addition he said, "I don't have much vision in my
right eye at the moment, but that may improve." Nonetheless,
Gelernter vowed to come back, on a limited basis, this fall.
Summing up his perspective on the ordeal, Galernter wrote: "I am
the luckiest man alive (emphasis on alive). Surviving the
explosion was evidently a pretty neat trick on my part, and I
could have been hurt much worse. Whenever I get to feeling a bit
morose and missing my old right hand, I wind up thinking instead
how privileged I am to be an academic in computer science; in the
final analysis, one decent typing hand and an intact head is all
you really need, if you wish to add the family and friends with
which I am blessed."

Despite the fact that the majority of dinosaurs are believed to

less appetizing than a yummy stand of palm trees, Ronald McDonald
Children's Charities has provided funding for what is being
billed as the most ambitious excavation of dinosaur fossils ever
undertaken in the Sahara Desert. The four-month expedition, begun
last month, is being conducted by paleontologist Paul Sereno of
the University of Chicago. The expedition is taking place in
Africa, Sereno says, because it is the "least-explored continent
for the story of dinosaur evolution." While Africa was drifting
free of other continents 100 million years ago, dinosaurs and
land plants evolved into species unique to that continent,
paleontologists say. Sereno returned from a preliminary trip to
the Sahara in 1990 with a six-foot-long femur bone from a
brontosaurus-like dinosaur that was at least 50 feet from head to
tail. A film crew and a still photographer will chronicle the
expedition; the resulting documentary is scheduled to air as the

for the past 15 years, producing the goats presented special
challenges, says Benjamin G. Brackett, head of the department of
physiology and pharmacology at the vet school: "A major obstacle
was to find the conditions that will enable eggs taken from the
ovary to mature appropriately prior to fertilization. In these
experiments, we carried immature eggs up to the four- to eight-

TI : Science Publishing Is Urgently In Need Of Major Reform
AU : RUSTUM ROY
TY : OPINION
The function of science publishing today is to get information
about new findings in science to at least three different
communities:
* Group A, the specialists working in the same field as that in
which the findings were made (numbering anywhere from 10 to 1,000
scientists);
* Group B, the general community of scientists and engineers who,
although not in that field, are nevertheless interested in major
advances in scientific areas other than their own--advances that
may, indirectly or in the long term, be significant to them
(probably between 1,000 and 10,000);
* Group C, the general, attentive public and the policymakers who
want or need to know of scientific developments that could have
economic or social consequences (10,000-100,000).
The classic media for science publishing--journals put out by
societies and other discipline-oriented organizations--were
designed only for Group A, while the media serving Group B are
the short news articles in society house organs, such as Chemical
Engineering News, Physics Today, and MRS Bulletin, and in such
multidisciplinary publications as Science and Nature.
Group C is served (very poorly, in my opinion) by the general
media--including newspapers and magazines such as the New York
Times, Omni, and Discover--which tend to overamplify and
inappropriately dramatize the "breakthroughs" they consider
newsworthy. Since maximum publicity--not accuracy--today serves
both the scientist and the journalist, these and other such
publications, in my opinion, tend increasingly to fall for
exaggeration and hype. Meanwhile, such publications as New
Scientist and The Scientist seek to bridge with both accuracy and
social relevance the B and C groups.
Confronted by such a menu of publishing alternatives, how does
the responsible scientist announce effectively a discovery that
she or he thinks would be of interest to one or all of the A, B,
and C groups?
The Establishment Position
The route accepted by the establishment is that one should submit
one's research report to a standard journal (the A group), have
it go through the arcane ritual called "peer review," and--only
after it has been accepted and published--send publicity releases
or other notification of its findings to the wider press.
The process is deficient, in my opinion, first of all because
peer review--the first hurdle--is biased against innovation. In
the path toward publication in the A-group journals, anything
that extends beyond the current ruling paradigms of scientific
thought will most likely experience inordinate delays in being
considered; matters of routine science will get into print much
faster. (There is an accompanying danger: that during the peer-
review process, especially when an article is dealing with a
dramatic discovery in a fast-breaking field and has potentially
profitable application, two or three scientists--the so-called
peers--and, hence, possibly their laboratories, companies, and
colleagues may inappropriately be privy to advance information on
a significant innovation that they can use to their own
professional gain.)
I strongly believe that when research results are really
important, they deserve a wider academic audience than the
specialized readers of the A-type journals and that, in line with
this, the significant scientific innovations of today need new
methods of publication.
Beating The System
A good example of how a creative scientist can circumvent the
current publishing system in order to get his or her significant
work out to the public is the case of Henry Heimlich, president
of the Heimlich Institute in Cincinnati. Although Heimlich does
not fit the traditional profile of the basic lab researcher
working toward an esoteric advance, his approach is worthy of
emulation: When he discovered his now-famous life-saving maneuver
for discharging obstructive material from the windpipe, he wanted
to get news of it without delay to the public who could use it.
After agreeing with the editor of Emergency Medicine (a non-peer-
reviewed journal) to simultaneously send out a story to the
general press, he published it in the June 1974 edition of that
publication (6:154-5, 1974). Newspapers all over the United
States picked up and ran the news release sent to them. Although
the Journal of the American Medical Association made note of
Heimlich's technique in a news blurb a few months later, the
technical article in JAMA did not appear until October of the
following year (234:398-401, 1975). By this time, of course, the
Heimlich maneuver was already saving lives all over the world.
For the bench scientist, the effort to penetrate or circumvent
the peer-review barrier in the way that Heimlich did can be
perilous indeed to the prospect of ever seeing a research report
in print. I know this from several personal, time-wasting
experiences with leading science journals. For example, in
October 1992, having made a scientific advance in diamond
synthesis, I sent off a paper to Science, then held a press
conference in Washington discussing my findings. At the press
conference, I handed out copies of the paper, and I also
distributed some copies by fax. After a month, Science returned
the paper--unreviewed, yet rejected--on the procedural ground
that preprints had been distributed, which, in Science's terms,
constituted publication.
An Obsolete Process
For the A group, the classic model of writing a paper, submitting
it to an editor, and having it go through the arcane peer-review
system described above may once have been suitable for science
done by an elitist minority (known to each other) with relatively
high ethical standards. But the A community itself is no longer
well served by this process because of several factors--and the
process is clearly inadequate to address the needs of groups B
and C. Among the factors are:
* The volume of the current literature is so large that peers and
editors have greater difficulty in determining whether work
reported is really significant or has been done before. (Indeed,
I believe that significant numbers of working academic scientists
essentially ignore the literature as they go about their
investigations.)
* The peer-review process as now practiced in most journals is
biased against real innovation, in part because of problems
associated with selection of knowledgeable and objective
reviewers. Even the key word in the term "peer review" is
difficult to define: Who, for example, is a "peer" of Linus
Pauling? Any assistant professor of chemistry at a university?
His arch-enemies in the anti-vitamin C camp? Yet, although no
clear definition of "peer" has as yet been created, the term
continues to be used by the science publishing industry as its
needs require. Most devotees of the process forget that the peer-
review system cannot be any guarantor of correct or good science;
all its practitioners really can do is check the plausibility of
the case and determine whether the author got the sums right.
* The current process in a peer-reviewed journal also gives an
unfair advantage of from three to six months in a given field to
two or three groups or individuals who are chosen to review an
article. This may be no problem for pedestrian science, but it is
unacceptable in many cases, especially those of interest to
groups B and C.
Devotees of peer review commonly assert that there are no
alternatives to the system. For research proposals, however,
there are dozens of alternatives in use all over the world. At
the U.S. Department of Defense, for example, a knowledgeable R&D
manager seeks out the very best researchers and takes the
responsibility for judging the best proposals with no authority
at all being given to peers. Every mid-level or higher manager in
industry does the same every day with no help from peers. For
publishing papers, the science community, in theory devoted to
"experimentation," often appears unwilling to try new approaches
for the new situations, although there have been exceptions. In
1965, I participated in the founding of the Journal of Materials
Research Bulletin. This journal, which has a good impact factor
in citations, runs open review either by associated editors or by
anonymous reviewers. Until recently, the Proceedings of the
National Academy of Sciences did not mandate peer review. Quality
presumably was maintained by examining an author's previous track
record. However, this is no longer true for PNAS.
Recommendations
I believe that new journals should be started (or new sections
started in established journals) for non-reviewed papers by
authors who establish their credentials by their track record. In
this process, a scientist who submits a list of published works
with a minimum of, say, 50 or 100 papers in the regular peer-
reviewed journals could publish a paper with only a brief delay
in the process for copy editing. Or any scientist with the same
or an even better track record could officially communicate a
colleague's paper.
This scheme would achieve several goals at once. First, it would
open up the system to genuinely new ideas. Second, it would speed
up the process by several months. Third, it would bring some
lively debate into science by having authors use the media Group
B to discuss or critique the work. Fourth, it would protect the
new work from some of the dangers inherent in the current
system--such as the prospect of the paper's never being
published.
In the case of a paper reporting on what the author considers an
especially impor- tant research advance that would be of interest
to audiences B and C, as well as A, standard practice should
entail the author's first sending the manuscript to a journal,
then distributing preprints by mail and fax, or calling a press
conference or doing whatever else is necessary to get the word
out.
Meanwhile, reporters covering such an announcement should examine
carefully the claims and explicitly report the author's previous
track record in the field. This is by far the best predictor of
reliability. And the reporters should seek comment on the
record--in radical contrast to the anonymity of peer review--from
other knowledgeable colleagues on the available preprint version.
The reporters should be skeptical of any claims the paper makes
concerning applications of technological or economic impact,
preferably ignoring them.

COMMENTARY
TI : In Animal Rights Debate, The Only Valid Moderates Are Researchers
AU : Frederick K. Goodwin and Adrian R. Morrison
TY : OPINION (COMMENTARY)
PG : 12
The article titled "In Animal Rights Debate, A `Modulating
Influence' Is Misunderstood" (R. Roth, The Scientist, May 31,
1993, page 11), correctly describes the important work under way
at the Johns Hopkins Center for Alternatives to Animal Testing
(CAAT). Author Robert Roth rightly defends CAAT's search for in
vitro and other non-whole-animal methods that can be used in
developing and evaluating therapeutic products for human and
animal use.
Yet, in characterizing CAAT as a "modulating influence in the
animal rights debate, in which extreme emotionalism and lack of
rational thought are too often the major players," Roth clouds a
major issue. He missteps by implying that there is a "middle
ground" position, flanked on one extreme by defenders of animal
research and, on the other, by animal rights advocates.
No consensus can be reached between those who accept the use of
animals for important human needs and those who categorically
reject animal use based on a philosophy that views all forms of
sentient life as morally equivalent. If the question
fundamentally is whether to use animals, no middle ground exists.
Use cannot be partly ethical; it is either ethical or unethical.
People who genuinely want to discuss the matter with researchers
must first disavow the animal rights position. To engage in
middle-ground discussions with true believers in animal rights
is, at best, fruitless; at worst, it provides animal rights
activists with a tactic to shift the uninformed closer to the
ultimate goal of total abolition of animal use. Only if one
starts from the principle that the use of animals is acceptable
does the issue of how animals are used address the
spectrum of legitimate issues.
One end of this spectrum holds that we should spare no expense to
provide absolute comfort and procedural safeguards for
experimental animals; a corollary of this extreme animal welfare
position is that research goals have to be secondary to the
absolute commitment to animal comfort. The other end of the
spectrum holds that humane treatment should not be a
consideration if it involves any extra expense or
inconvenience that animals can be treated essentially like
lab equipment. Between these two extremes, the biomedical
research community occupies the middle ground. We are engaged in
legitimate, important debates about regulations vs. costs and
about animal welfare vs. human needs, answerable only through
research that encompasses the humane use of animals.
Medical science has no counterpart to the statement "In no case
are animal studies the foundation for progress," uttered by Neal
Barnard, founder of the Physicians Committee for Responsible
Medicine (AV Magazine, April 1989, page 17). Does Barnard, a
physician, truly believe that vaccines, antibiotics, implantable
prosthetic devices, and immunosuppressant drugs were tested
willy-nilly on human patients without research and testing on
animals? If he concedes that animal research played a role in
early medicine, does he believe that "prevention" could eliminate
genetic diseases such as cystic fibrosis, which is now closer to
effective treatment because of animal research identifying the
genetic anomaly?
Nor can medical science rationally counter the statement of Chris
DeRose, president of an organization called Last Chance for
Animals, that "A life is a life. If the death of one rat cured
all diseases, it wouldn't make any difference to me" (Los Angeles
Times, April 12, 1989, page E12). And what should we say to the
comment of Ingrid Newkirk, national director of People for the
Ethical Treatment of Animals, that "Even if animal research
resulted in a cure for AIDS, we'd be against it" (Vogue,
September 1989, page 542)? We doubt that many scientists would
knowingly stand with Newkirk and DeRose against their fellow man.
The anti-intellectual, anti-scientific actions of animal rights
activists have seriously harmed biomedical research and, in turn,
the public. Laboratories have been destroyed; scientists
vilified; their homes picketed and damaged. Research programs
that promise real cures for human misery have been impeded.
Animal protection "moderates" who do not condemn these activities
speak volumes by their silence. There is room for emotionalism;
the anger of medical scientists is both justified and healthy.
Non-medical readers should investigate the situation. They'll get
mad, too.

LETTERS
TI : Redundant Publication
TY : OPINION (LETTERS)
PG : 12
I welcomed Paul McCarthy's article "Vigilant Science Journal
Editors Fight Redundancy" (The Scientist, March 8, 1993, page 1).
I would like to offer the following comments in response.
The first concerns the naivete of researchers who think a long
bibliography is the key to recognition and promotion. Speaking as
one who has served on admissions committees, academic promotion
boards, editorial boards, and National Institutes of Health study
sections, I can only wonder what sort of fools such aspirants
take us for.
In my experience, those who review candidates for admission or
promotion are quite aware of what McCarthy calls redundant
publication: They take it into account not only in reviewing
candidates, but also in judging the quality of journals. The
first thing I do when examining a bibliography is to search for
meritorious contributions in well-edited journals. After these
are subtracted, remaining redundancies must work to a candidate's
disadvantage. I also find that most sophisticated reviewing
committees are as interested in the quality of contributions as
in the quantity.
My second point concerns a pernicious and growing practice of
journals that surely contributes to the redundancy problem. It is
the trend toward listing as authors half as many names as appear
in an average metro phone book. Recent issues of the New England
Journal of Medicine, for example, include articles with 20 or 30
authors. Do these individuals actually believe that being one of
such a crowd adds credibility or gravitas to their bibliography?
The time has come for journals to devise less burdensome methods
of recognizing contributors. One that comes to mind is a simple
footnote that names everyone, while authorship is left to a few
key individuals. Or, as sometimes happens nowadays, authorship
might be attributed to a group or committee, with all names
omitted.

TY : OPINION (LETTERS)
Patrick Cleveland accuses me of "artful use of language" (The
Scientist, May 31, 1993, page 12) in my defense of the Humane
Society of the United States (HSUS) against his
mischaracterization of the organization (The Scientist, Feb. 22,
1993, page 10). Yet his verbal attacks border on McCarthyism,
with the suppression of animal rights activism being the new
goal.
His main thesis is that HSUS is now a radical animal rights
organization seeking to abolish all animal research and differing
from other such organizations only in tactics. In Cleveland's
view, HSUS's humane education efforts to nurture compassion and
kindness become "attempts to redefine human moral value systems"
and therefore should be examined to see if they are "brainwashing
our children."
The two most defining aspects of HSUS in the area of animal
research are our current policy and programs. Cleveland ignores
both. Instead he cites, out of context, statements and events
from 1980 and 1984. His lone example of more recent vintage
(1990) illustrates his confusion of the animal rights movement
and the actual rights of animals. The critical question, as
bioethicist Arthur Caplan has pointed out (If I Were a Rich Man,
Could I Buy a Pancreas?, Bloomington, Indiana University Press,
1992), is not whether animals have rights, but how their rights
are balanced against the rights of humans.
At the same time, however, HSUS does not consider itself an
"animal rights" organization or part of the "animal rights
movement" insofar as these political labels have come to refer to
organizations with abolitionist positions on using animals for
research, food, and so forth. HSUS does not have such positions
on these issues. Accordingly, for clarity's sake, we use the more
inclusive term "animal protection" to characterize ourselves.
Cleveland's ad hominem attacks divert attention from what HSUS
views as the primary issue in the animal rights controversy,
namely, what can and should be done to reduce the harmful use and
suffering of animals in laboratories.

RESEARCH
TI : Huge Microbe's Value Lies In More Than Just Sheer Size
AU : MYRNA E. WATANABE
TY : RESEARCH
PG : 14
"Word's biggest bacterium found in a fish," declared the front-
page headline in a March 1993 edition of USA Today, while the New
York Times trumpeted its coverage with: "In the world of
bacteria, a behemoth." Even the relatively staid science journals
couldn't resist. Science announced the identification of
"Monsters from the guts," and Nature's header read "Giant among
the prokaryotes."
The extraordinary flurry of interest--and imagery--was over an
article in Nature (E.R. Angert, et al., 362:239-41, 1993)
reporting the identification by microbiologist Norman R. Pace's
laboratory at Indiana University in Bloomington of the largest
bacterium yet known to science: Epulopiscium fisheloni.
The organism, a member of the Clostridium group of anaerobes, had
been, according to the report, isolated from the intestine of the
brown surgeonfish, Acanthurus nigrofuscus, and it is, indeed,
big--up to 600mm long by 80mm in diameter. That translates, the
Times reported, to "about the size of a hyphen in a newspaper
article."
While grateful for the publicity that identifying the bacterium
has gained for him and his colleagues, Pace believes that the
media hype surrounding the organism's sheer bulk obscured the
true value of his lab's achievement. In fact, Pace's interest in
this specific organism is not nearly so great as is his interest
in the use of techniques his laboratory staff has developed to
screen microbes found in the environment.
According to Pace, their work can be broadly described as
"characterizing naturally occurring microbial organisms without
cultivating them." Thus, the media attention given to his lab's
latest find was most valuable in, if anything, drawing attention
to the techniques' usefulness in opening the door to the world of
as-yet-undiscovered microbes.
"We know so little about the natural microbial world," says Pace.
"Imagine if our entire view of biology was based on a visit to
the zoo. That's exactly the situation we're in in the context of
the natural microbial world."
Need For Cultivation
Until now, technology to study the microbial world has been
limited. Under normal circumstances, an individual bacterium will
not yield any information about itself by being taken from its
natural environment, stained, and viewed under a microscope.
Since it can be effectively studied only in numbers, it must be
grown in media to produce colonies.
Carl Woese, a professor of microbiology at the University of
Illinois, Urbana-Champaign, and coauthor of several papers with
Pace, explains that the problem with understanding the microbial
environment is that until now, available methods limited
researchers' ability to find, let alone identify, microorganisms.
Newer biochemical techniques, such as using probes with known
complementary DNA or RNA codes from identified organisms, along
with DNA sequencing, could revolutionize microbiology, many
researchers agree.
"A large fraction of the bacteria [have] been studied by
enrichment culturing," Woese points out. "We artificially enrich
and then select those [bacteria] which grow best on the media of
our design"--that is, bacteria grown on artificial nutrient media
such as agar enriched with amino acids, salts, and other
molecules. The media becomes the bacteria's environment, and
those bacterial strains that grow best into colonies on the media
are the ones with which scientists currently are best acquainted.
However, enrichment culture, although the basis of much of our
knowledge of bacteriology and microbial pathology, is of very
limited use in exploring the entirety of the world of living
microbes. Enrichment culturing is highly selective; according to
Pace, only between 1 in 1,000 and 1 in 100,000 of bacteria
present in a given environment will grow on enriched culture
media. Thus, while a single bacterium in a particular soil sample
may be identified through enrichment culturing, the sample may
well contain tens of thousands of other organisms that can't be
grown in the available media and will thus remain unknown. It
follows, Woese points out, that "the natural distribution of
microorganisms tends to be very different from the collection we
have in the laboratory."
Innovative Approach
Pace's technique, however, can be used on organisms that, as yet,
have not been amenable to enrichment culturing: It involves the
amplification of DNA that has been extracted from a bacterial
cell. The resulting clones are then sequenced and compared with
known sequences for ribosomal RNA (rRNA). This allows
determination of what is called a "phylotype," or the position
where this organism fits in the known bacterial phylogeny.
Additionally, hybridization probes complementary to specific
regions of the rRNA are synthesized and used both to confirm that
the DNA in question came from the specific organisms being
studied and to aid in screening other organisms.
In the research on Epulopiscium, DNA amplification was done in
Pace's lab via polymerase chain reaction (PCR), reproducing
ribosomal DNA (rDNA) that codes for small subunit rRNA. In this
case, the fact that Epulopiscium hybridized with a bacteria-
specific hybridization probe and not one for eukaryotes
established that Epulopiscium is a bacterium. The organism
tentatively had been identified as a protozoan in earlier work
(L. Fishelson, et al., Science, 229:49-51, 1985).
W. Linn Montgomery, an ichthyologist at Northern Arizona
University in Flagstaff, was one of the original discoverers of
the organism, and his doubts that it was a protozoan led him to
persuade Pace to examine it. Pace, viewing this as a good
opportunity to establish the usefulness of his technique, showed
the microbe to graduate student Esther R. Angert, who was just
beginning her studies with Pace at Indiana. Pace asked her: "Look
here, do you want to study this?"
Samples of preserved surgeonfish gut contents were supplied to
the laboratory by Kendall D. Clements of James Cook University,
Townsville, Queensland, Australia. The organisms are so big that
Angert was able to pick them out of the intestinal samples under
a microscope, impossible to do with smaller bacteria.
Microbiologists, including Pace, willingly acknowledge the tech-
nique's limitations. For example, Bruce Hanna, an associate
professor of clinical pathology at the New York University School
of Medicine, who is using probes to identify the bacillus that
causes tuberculosis, says, "It's not going to replace everything.
First of all, it's very laborious and very expensive."
Angert's research illustrates the complexities. She began work in
1990 and finally came up with "the right ribosomal RNA" in the
fall of 1991. She then had difficulties, she says, "getting a
clean enough Taq polymerase." Fortunately, a colleague was able
to isolate and sufficiently purify the enzyme.
Pace explains that even though the work is expensive, research
money is available for studying high-temperature organisms, as
they are thought to hold the greatest commercial opportunities as
sources of thermostable enzymes.
Whither Epulopiscium?
Now that the Epulopiscium study is completed, Pace's group is
concentrating on microorganisms from high-temperature
environments at Yellowstone National Park. They already have
identified organisms that, Pace says, "are more different from
known organisms than known organisms are from one another."
And what will become of the giant symbiotic Epulopiscium? Angert
believes that microbiologists will be able to use this bacterium,
which is large enough to allow insertion of microprobes, to
directly study bacterial physiology, a process that cannot be
carried out with most known bacterial species.
The organism itself leaves many scientific questions unanswered.
First of all, large bacteria similar to Epulopiscium have been
found within intestinal tracts of herbivorous animals. For
example, Angert explains, "there are similar organisms in guinea
pigs. How did they get there?" Angert's study also found similar
bacteria in the intestine of Naso tuberosus, the humpnose
unicornfish, another herbivorous surgeonfish relative. These
symbionts clearly established themselves within the animals'
digestive tracts many generations ago. Researchers wonder: What
is their precise physiological function in the gut--and why did
they grow so large?
Montgomery believes that the bacteria "may enhance lipolytic
activity in the main intestine. We know they greatly suppress pH
locally in the mid-intestine." This, however, is only a part of a
long-term coevolu-tionary relationship.
Gareth Nelson, curator of ichthyology at the American Museum of
Natural History in New York, describes Acanthurus nigrofuscus,
the big microbe's surgeonfish host, as an Indo-Pacific
cosmopolitan fish species living throughout the Pacific and
Indian Oceans. Both he and Montgomery note that the true
taxonomic status of the species is unknown and it, because of its
broad distribution, is unlikely to be one valid species and is
more likely to be at least several separate species.
Montgomery, who has been studying the surgeonfish for many years,
says that Epulopiscium or similar microbes have been found in the
intestinal tracts of this fish from many parts of its range--
South Africa, Hawaii, Tahiti, Australia, and the Red Sea.
Angert's research showed that different types of the
microorganism inhabit the intestines of Australian fish and the
same purported species of fish found in the Red Sea. Questions
that arise include: Did the bacteria evolve along with the fish,
and can you study the phylogeny of the fish by studying the
molecular evolution of the bacteria?
"I think, in terms of coevolutionary stories, this has some great
potential," Montgomery says.
And the bacterium itself, according to microbiologist James
Staley of the University of Washington in Seattle, leads to some
interesting speculation: "What is the upper size limit for
bacteria? Is there some sort of reason why the cell can't get any
larger than this? "
Some advocates of Pace's approach suspect that it will be
criticized by the plate-and-cultivate researchers, who are used
to working with organisms they can colonize in culture, rather
than with one or two organisms, as Pace is doing. But NYU's
Hanna, who runs the clinical microbiology laboratory at New
York's Bellevue Hospital Center, is clearly impressed. "I think
what they have done is very unique and interesting," he says.
"They don't know what they're looking for .... Sometimes, it's
the only thing you can do."

TI : PAYING PROPER ATTENTION TO THE MICROBIAL WORLD
AU : MYRNA E. WATANABE
TY : RESEARCH
PG : 14
Indiana University microbiologist Norman Pace has been profoundly
interested in RNA since his work as a graduate student in the
laboratory of Sol Spiegelman at the University of Illinois.
Indeed, all of his 140 scientific publications deal, in some
manner, with RNA. As time and technology have progressed, Pace
has concentrated more and more on RNA as a key to molecular
evolution.
His laboratory currently has two foci: studying RNase P, an
enzyme that, in part, is composed of a catalytic RNA; and
developing methods for screening and analyzing environmental
microbes.
It is this latter focus that leads Pace to be a vocal advocate
for the study of microbial biodiversity. "The microbial world
established the biosphere; the microbial world still supports the
biosphere," he says. Researchers need "to find out what's out
there and what are they really doing," he says.
He and University of Illinois microbiologist Carl Woese--
considered by Pace to be the father of rRNA phylogeny (L.
Holland, The Scientist, May 14, 1990, page 22)--point out that
people making a big ruckus today about the need for preserving
biodiversity are speaking about only a very few species of plants
and vertebrate animals, largely ignoring the microbial world,
which is much more vast and is necessary for all life. For
example, without microorganisms there would not be degradation of
organic matter--no biological recycling. They further point out
that nowhere on the surface of the Earth is microbe-free,
including the oceans and even within rocks. "They grow throughout
the first few miles of the surface of the planet," says Woese.
Woese adds that by studying the origins of microbes,
microbiologists also are studying human origins. "The eukaryotic
cell that became a plant cell did not invent photosynthesis,"
says Woese. He explains that the origins of both chloroplasts and
mitochondria will be found in organisms similar to the microbes
that were captured by the earliest cells.
For their sheer longevity, microorganisms as a group deserve more
scientific attention. "How old are microorganisms?" asks Woese
rhetorically. "Three point five billion [years] is a conservative
estimate," he answers, with 3.8 billion years as a more realistic
estimate. Scientists cannot search back farther than that because
that is the age of the earliest rocks. The Earth is 4.5 billion
years old.

S. Dalton, R. Treisman, "Characterization of SAP-1, a protein
recruited by serum response factor to the c-fos serum response
element," Cell, 68:597-612, 1992.
Stephen Dalton (Roche Institute of Molecular Biology, Nutley,
N.J.): "Transcription factors often have separable DNA binding
and activation domains, indicating that they are functionally
modular. This is well illustrated by experiments showing that
GAL80 repressor protein can be made into an activator by fusing
it to a heterologous transcription activation domain (J. Ma, M.
Ptashne, Cell, 55:443-6, 1988). With this property of
transcription factors, an assay has been developed using yeast
that enables protein-protein interactions to be detected in vivo
(S. Fields, O.K. Song, Nature, 340:245-6, 1989).
"Our work is an early example of how this type of approach can be
successfully applied to screen for novel interacting proteins in
vivo. Our goal was to identify and characterize cDNA clones
encoding proteins that form part of a growth factor-regulated
transcription complex with the human c-fos serum response element
(and the already cloned serum response factor). With an
activation domain-tagged cDNA expression library, cDNAs were
isolated encoding proteins that complexed with a serum response
element in yeast. Our efforts identified a group of factors with
similar structure (SAP-1, elk-1), which interact with the c-fos
serum response element/SRF complex. Further work has established
that the elk-1 protein is a target for a mitogen-activated
protein (MAP) kinase (R. Marais, et al., Cell, 73:381-94, 1993;
C. Hill, et al., Cell, 73:395-406, 1993). This recent work has
accelerated progress in efforts to understand how signals
generated by growth factors at the cell surface modulate patterns
of gene expression.
"The approach of using activation domain-tagged cDNA libraries to
screen for proteins that interact with already characterized
proteins is now being used with considerable success in many
labs. One can imagine limitless situations in which this type of
assay could be used by investigators to identify new interacting
components in their systems. Substrates for kinases, ligands for
receptors, components of signaling pathways, transcription factor
complexes, and so forth are all obvious situations in which this
approach has potential applications. Furthermore, tagging
proteins with activation and DNA-binding domains is proving to be
a popular approach for investigating in vivo interactions between
already characterized multiprotein complexes. It will be
interesting to see if activator-tagged library interaction
screens of the type discussed here will be generally successful
for proteins besides transcription/replication factors,
especially those involving factors not normally localized to the
nucleus."

Thomas A. Steitz (Howard Hughes Medical Institute, Department of
Molecular Biophysics and Biochemistry, Yale University):
"Interfering with the activity of proteins specified by the human
immunodeficiency virus (HIV) is one strategy for treating AIDS.
The currently approved anti-AIDS drugs (AZT, ddI, and ddC) act
through HIV reverse transcriptase, which incorporates them into
the DNA viral copy being synthesized, resulting in DNA chain
termination. An emerging approach to designing new
pharmaceuticals is to use the three-dimensional structure of the
target protein to craft small molecule inhibitors that fit the
protein surface snugly and thus bind tightly. To engage in this
protein structure-based rational drug design requires knowledge
of the complete three-dimensional structure of the protein that
is the target. The first HIV protein whose structure has been
determined is the protease, which is now the target of extensive
rational drug design efforts.
"In our 1992 Science article we describe the first crystal
structure of HIV-1 reverse transcriptase (RT) at a resolution
sufficient to trace the course of the polypeptide backbone and
gain new insights into its mechanism. The structure, even at this
initial phase, will be of use for making and solving additional
crystal forms of the enzyme, designing strategies to inhibit the
enzyme, understanding the structural bases of mutations that
render it insensitive to drugs, and developing new inhibitors. RT
was co-crystallized with a noncompetitive inhibitor, Nevira-pine,
a potential anti-AIDS drug that facilitated obtaining crystals of
RT that diffract to at least 2.8 resolution. This
crystallization strategy is now being followed by other
laboratories to obtain improved crystals of this enzyme. Perhaps
the most surprising and striking aspect of the structure of the
heterodimer is the observation that the polymerase domains in the
p66 and the p51 subunits have very different structures although
they have the same amino acid sequence. We hypothesized that this
asymmetric structure allows formation of the large binding site
for tRNA that is the replication primer and the viral genome
template. Use of the same polypeptide for more than one function
allows viruses to increase the information capacity of their
small genomes.
"This structure determination of RT and the future structural
work that it facilitates will be important in the rational design
of new inhibitors of HIV RT and the modification and improvement
of existing inhibitors. Chemists at Boehringer Ingelheim Corp. of
Danbury, Conn., under the direction of Julian Adams, have made a
modification to Nevirapine, guided by the structure, that now
more effectively inhibits all of the RT mutant enzymes that are
resistant to the unmodified Nevirapine. At best, the structure
can only suggest ideas for new--and modifications of known--
inhibitors as well as eliminating many unfruitful directions of
inhibitor design. However, the protein structure may serve to
bias the random walk toward the synthesis of new pharmaceuticals
and thereby increase the pace of their development."

TI : Antibody Suppliers Offer An Array Of Inventive Lab Tools

Monoclonal antibodies (MAbs) haven't quite lived up to
researchers' early expectations that they would be "magic
bullets" in the clinic, zeroing in on abnormal cells and sparing
the healthy ones. Nonetheless, in the laboratory, the number of
applications of these preparations of pure, single-type
antibodies are soaring.
"From a research standpoint, MAbs will provide tremendous tools
in identifying protein markers and changes in gene expression.
>From a diagnostic standpoint, MAbs will be the best tools out
there," says Claire Thuning-Roberson, director of the Goodwin
Institute for Cancer Research Inc. and president and chief
executive officer of its recently formed for-profit subsidiary
Goodwin Biotechnology Inc., both in Plantation, Fla.
And that's why antibody suppliers are very busy. "Time is
valuable and critical to researchers. They often prefer an
antibody that they can just grab off the shelf, rather than going
through the labor and development time" needed to derive their
own antibodies, says Douglas McAllister, president of ViroStat
Inc., a Portland, Maine-based antibody supplier.
Today, the diverse uses of MAbs include detecting respiratory
viruses, pregnancy, drugs of abuse, and turf grass disease. MAbs
are a continuing and growing presence in the basic life sciences
and in biotechnology, their uses paralleling research trends.
Why Antibodies?
An antibody is a protein manufactured by an animal's immune
system's B cells in response to a foreign molecule, or antigen.
In vivo, the antibody response is polyclonal--different B cells
zero in on different parts, or epitopes, of the target. The
polyclonal antibody response sends several different types of
antibodies into the blood serum. Polyclonal antibodies are
valuable as tools to detect more than one antigen, such as the
different proteins in the tangles of an Alzheimer's disease
sufferer's brain, or mirror-image forms of an enzyme.
MAbs have long been a favorite tool of biologists because of
their great specificity. In 1975, Georges Kohler and Cesar
Milstein at the Medical Research Council Laboratories, Cambridge,
England, developed a way to obtain such antibodies by fusing a
mouse's B cell, which supplies the single antibody type, to a
mouse's cancer cell, which immortalizes the cell line (G. Kohler
and C. Milstein, Nature, 256:495-7, 1975).
A dramatic example of the specificity of a MAb was the so-called
poppy seed defense. To investigate several questionable cases of
military personnel whose urine tested positive for opioids, five
soldiers at the Forensic Toxicology Drug Testing Laboratory at
Tripler Army Medical Center in Honolulu gorged on breads and
pastries whose generous garnishes of poppy seeds were carefully
quantitated. Four of the five volunteers tested positive for
opioids on standard tests. A MAb, however, helped exonerate them
by differentiating more specifically among the chemical presences
detected--it homed in on 6-monoace-tyl morphine, a metabolite
found in the sweets but not in opioid drugs.
But making a hybridoma cell that produces precisely the antibody
type needed for a particular experiment is labor-intensive and
time-consuming. And that's where companies come in--supplying
antibodies (monoclonal and polyclonal) and providing contract
services to nurture and select hybridomas, then scaling up
secreted MAb products.
According to Bret Wien, president of Research Diagnostics Inc.,
Flanders, N.J., a researcher's investment in developing a
hybridoma may be worthwhile if the work requires large quantities
of the antibodies, but the results may be unpredictable. "A lot
of research centers make their own [antibodies]--but sometimes
they find that the antibody doesn't do what they want it to do,"
he says.
Another plus to purchasing antibodies--either standard or custom-
produced--is that they can be labeled to a user's specifications.
Commonly used conjugates in medical imaging applications include
radiolabels such as indium-11, iodine-131, and technetium-99m.
Goldmark Biologicals, Phillipsburg, N.J., provides a range of
services for its colloidal gold conjugates, including supplying
pre-gold-labeled antibodies or kits for researchers to do their
own labeling, as well as offering custom-gold-labeling of
antibodies. Gold labeling coats a suspension of fine gold
particles with antibodies, making them visible in the light or
electron microscope (W. Faulk and G. Taylor, Immunochemistry,
8:1081-3, 1971). The technique is sometimes combined with a
silver enhancement step. Other common labels for antibodies
include algal pigments called phycoerythrins and the standard
compounds fluorescein and biotin.
The great diversity of antibody companies covers almost any
research need. Some suppliers' catalogs list hundreds of
products, representing a veritable zoo. Organon Teknika Corp.,
Durham, N.C., for example, sells antibodies from guinea pigs,
cats, rabbits, dogs, goats, swine, sheep, chickens, cows, horses,
monkeys, and other animals. Accurate Chemical and Scientific
Corp., Westbury, N.Y., offers an equally extensive catalog.
Some companies focus their product line. "ViroStat specializes in
infectious-disease antibodies. Our respiratory products are
always in demand, such as respiratory syncytial virus,
adenovirus, and influenza virus," says McAllister. MAbs from
Repligen Corp., Cambridge, Mass., and Viral Testing Systems,
Houston, bind to key HIV glycoproteins. And Stress Gen
Biotechnologies Corp. in Victoria, British Columbia, Canada,
specializes in stress-related proteins.
Sufficient MAbs for 100 to 200 determinations typically cost a
few hundred dollars. Custom MAb services run higher--but for good
reason, as a look at services provided by the Berkeley Antibody
Co. (BAbCO) of Richmond, Calif., illustrates.
Birth Of A MAb
In developing a MAb, researchers first immunize and test mice for
an antibody response. Next, they isolate B cells from the
animals' spleens and fuse them by exposure to polyethylene glycol
with mouse myeloma cells. The resulting hybridomas can then be
cultured in 96-well plates, and those secreting antibodies
identified. After three weeks of growth, the researchers test
supernatants from secreting hybridomas against various antigens
to determine their specificities. The hybridoma selected is then
expanded and cryopreserved.
The total price tag for development and support of a hybridoma
ranges from $7,000 to $14,000, and the process takes four to six
months. Most projects require two spleens, each yielding about
100 million B cells. One in a million B cells successfully fuses
with a cancer cell to form a hybridoma.
BAbCO's clients are predominantly academic, says Tracy Clark,
innovative products manager, although several biotech companies
and larger pharmaceutical firms are included in the group. Clark
heads a company effort to develop novel MAbs that will eventually
be commercially available. "For example, we have generated
antibodies against estrogen and progestin receptors, cyclic AMP,
growth hormone, and prolactin," she says.
For academic researchers with limited budgets, a popular option
is the National Cell Culture Center in Minneapolis, a National
Institutes of Health research facility located on the premises of
Cellex Biosciences Inc. (Cellex staff received a five-year grant
from NIH to establish and run the center.) "We are charged with
doing large-scale cell culture for university researchers doing
basic research. They send in a cell line, and we play with the
media, use bioreactors, produce one gram or as much as 30 to 40
grams," of the MAb, says Mark Hirschel, director. "NIH picks up
laboratory expenses, overhead, providing equipment. All the
clients have to come up with are consumables, such as media and
serum," he adds. Holding an NIH grant is not a prerequisite for
using the center, but doing basic research is, "as long as
ultimately the results of the research will be available in the
public domain," he says.
Humanization
Some firms work to make animal MAbs more like human MAbs. "MAbs
were going to be the magic bullet in the 1970s--but there were
problems. You couldn't inject mouse antibodies into humans,
because the body would generate antibodies to the antibodies. So
now there are efforts to humanize MAbs, cutting up the antibody
so it is still active, but the immune system isn't activated,"
says Wien.
Researchers take many clever routes to humanizing MAbs, including
creating mouse/human hybrid hybridomas, cloning human antibody
genes in bacteria, or taking a murine antibody apart, amino acid
by amino acid, and building a human version. Viral Testing
Systems, for example, produces all-human MAbs against parts of
HIV. The company's scientists take an antibody-producing B cell
from an HIV-positive individual and fuse it with a cell from
lymphoid tumor cell line. They then culture cells that produce
antibodies while monitoring for the virus. The client gets HIV
antibodies from a human hybridoma system, with no risk of viral
contamination.
The attraction of monoclonal antibodies is that their specificity
can be applied to nearly any research situation to dissect the
molecular underpinnings of biological phenomena. MAbs have become
crucial tools in studying cytokine interactions, signal
transduction, stress response, and carcinogenesis. One area
currently of great interest is cell adhesion, which is mediated
by cell adhesion molecules, or CAMs. These proteins and
glycoproteins protrude from cells, orchestrating their
interactions in a wide variety of processes, including cellular
differentiation in the embryo, cancer biology, wound healing,
inflammation, and blood clotting.
For example, analysis of CAM activity reveals that the slow
movement of white blood cells through capillary walls to the site
of an injury is actually a complex, coordinated sequence of
molecular attractions and attachments. The white blood cell is
initially slowed by CAMs called selectins, which coat the cell,
halting its turbulent circulatory rush by binding carbohydrates
on the endothelial cells that form the tile-like wall of the
capillary.
Then, chemo-attractants secreted by the damaged tissue orient the
white blood cell by activating other CAMs on it called integrins.
Finally, integrins bind adhesion receptor proteins extending from
the capillary wall at the site of the injury. This pulls the
white blood cell between the endothelial cells, clearing a path
to the injury site.
MAbs can help researchers dissect this leukocyte trafficking and
other cellular adhesion processes by isolating individual steps.
And antibody firms are capable of supplying the MAb tools that
can make this happen. Becton Dickinson Advanced Cellular Biology,
San Jose, Calif., for example, offers several selectins,
integrins, and other CAMs in its CAMFolio Monoclonal line of
products. Another CAM supplier is Endogen Inc., Boston, which has
an agreement with the Houston-based M.D. Anderson Cancer Center
to commercialize adhesion MAbs.
Selectins and integrins have been the objects of intense research
interest for a few years. Newer are the cadherins, CAMs that
control cell sorting during development. "Cadherins are a major
player in morphogenesis, but the most exciting aspect is that
down regulation of cadherins is associated with the invasiveness
of tumors," says John Bliss, director of marketing at Zymed
Laboratories Inc., South San Francisco, Calif., the U.S.
distributor of anti-cadherin MAbs for TaKaRa Biomedicals Ltd. of
Shiga, Japan.
"You can use MAbs to cadherins to study the cause and effect of
metastasis," he says. "It looks like metastasis is related to
cadherin binding, but no one knows how yet." The MAbs became
available in June.

TI : MacArthur Fellows Swim Against Scientific Mainstream
AU : LEE KATTERMAN
TY : RESEARCH
PG : 19
Over the last 13 years, the Chicago-based John D. and Catherine
T. MacArthur Foundation has surprised and pleased 414 scientists,
artists, writers, and social activists by providing them with a
prestigious five-year, unrestricted MacArthur Fellowship. The
program's goal is to honor individuals whose accomplishments and
creativity indicate that this award is likely to spur them to
still greater heights.
"This is perfect," is how Margie Profet, one of this year's
winners, puts it. Profet, 34, a research associate at the
University of California, Berkeley, says her MacArthur Fellowship
will give her the means to concentrate on finding evolutionary
explanations of human physiological traits, such as menstruation,
instead of having to support herself by working for other
scientists and doing her own work on the side.
A MacArthur Fellowship is also special because the processes of
nominating and selecting awardees are completely confidential.
Fellowship winners are given little insight into why they have
been chosen, nor do they receive instructions for how to spend
their grants, which range from $160,000 to $375,000, varying with
the recipient's age.
This year, 13 of the 31 new MacArthur fellows are scientists.
What kind of researcher attracts the admiration of the
foundation's secret selectors? Since the anonymous committee
members cannot be interviewed, The Scientist asked the
awardees themselves to speculate on what may have led to their
selection.
Doing Their Own Thing
Several scientists speak of their willingness to swim against the
mainstream. Take energy efficiency expert Amory Lovins, 45,
director of research and cofounder of the Rocky Mountain
Institute in Snowmass, Colo.
Lovins and his colleagues at the institute examine problems
related to energy, water, agriculture, transportation, security,
and the links among them. He says that ideas bucking the
conventional wisdom are an "overly abundant resource at the
institute. We try to think of ways to solve one problem without
making a lot of new ones.
"Most of us here describe our hierarchy of needs as: save the
world, have fun, and make money, in that order."
Being selected is a validation of some "unusual" career choices
for Ellen Silbergeld, 47, chief toxics scientist with the
Environmental Defense Fund in Washington, D.C., and a professor
of epidemiology and toxicology at the University of Maryland
Medical School. Silbergeld studied history as an undergraduate,
later taking up environmental medicine and neuroscience. Her
position at the Environmental Defense Fund meant leaving the
National Institutes of Health, where she had been a research
scientist in neuroscience and reproductive toxicology for nine
years. Silbergeld now uses real-world problems--for example,
investigations of why lead causes brain damage--to guide her
basic research in neuroscience.
Social Consciousness
Public policy concerns have been prominent in the scientific
careers of several other 1993 MacArthur fellows, as well. Jane
Lubchenco, a marine biologist at Oregon State University, says
that, compared to 10 years ago, when she focused on teaching and
basic research, she now spends much more time on applied problems
at the "interface of basic research and human activity."
Lubchenco, 45, recently headed the Sustainable Biosphere
Initiative for the Ecological Society of America, a committee
that set priorities for future ecology research according to the
needs of pressing environmental problems. "We need to make some
pretty drastic changes [in our approach to the environment] if we
hope to achieve sustainability," she says.
Frank von Hippel, 55, a physicist and a professor of public and
international affairs at Princeton University, speculates that
his work in developing a technical underpinning to nuclear
disarmament probably played a big part in being selected for a
MacArthur Fellowship.
Another Princeton physicist who received a MacArthur Fellowship
this year is 53-year-old Robert Williams of the university's
Center for Energy and Environm |
