July 1998

T he Senate's snuffing of anti-tobacco legislation last month also extinguished some optimism for increased science funding for fiscal year 1999, which begins Oct. 1, 1998. "It's definitely a setback," Mary Woolley, president of Research!America, admits. President Bill Clinton had earmarked some of the anticipated revenue from proposed increases in cigarette taxes to pay for a boost in biomedical research funding. Without that revenue, Research!America's goal of doubling biomedical research fu

REVELATION: The glycoprotein gp120 binds to the CD4 receptor on the T cell, causing the viral molecule to contort in a way that enables it to bind to the nearby chemokine receptor, too. This dual binding of HIV to two co-receptors triggers fusion of the viral and T cell membranes. Infection begins. X-ray crystallography has played a pivotal role in life science research, from providing data crucial to deciphering the DNA double helix, to revealing the structure of HIV protease. Now, the techn

In light of several high-profile court cases on patenting of DNA sequences, the U.S. Patent and Trademark Office (USPTO) in June issued interim guidelines for helping patent examiners determine if the so-called "written description" requirement for patent applications has been met. John J. Doll, director of biotechnology examination at USPTO, says the interim guidelines have become necessary to determine just how court decisions such as University of California Regents v. Eli Lilly and Co. wil

Leaders of separate public and private efforts to sequence the human genome used words such as "cooperation," "collaboration," and "partnership" to describe their intentions toward each other during a hearing last month in Washington, D.C. But both projects appear headed on separate, although not quite independent, courses. The private project--a joint venture between Perkin-Elmer Inc., a Norwalk, Conn.-based manufacturer of sequencing equipment, and J. Craig Venter, president of The Institute

Commencement ceremonies this spring at many colleges and universities across the country honored not only graduating students, but scientists hailing from a variety of fields. In recognition of their achievements, dozens of scientists received honorary degrees; some also offered words of advice to graduates. The speeches included the usual all-important cliches: Strive to be your best. Take risks. Seize opportunities. Retain your individuality. Learn for the sake of learning. However, several s

"That's Dr. Bradshaw. If you ask him how many degrees he has, he answers in kilograms."

Volume 12, No. 14The Scientist July 6, 1998 CLARIFICATION Date: July 6, 1998 The research on the gas additive MTBE by Glenda J. Moser (G.J. Moser et al., Toxicological Sciences, 41:77-87, 1998) mentioned in a story on investigations in the field (S.P. Hoffert, The Scientist, 12[13]:7, June 22, 1998) was done exclusively at the Chemical Industry Institute of Toxicology in Research Triangle Park, N.C.

My first paper proposing the creation of the Science Citation Index® (Science, 122(3159): 108-111, 1955) began with a quotation from P. Thomasson and J.C. Stanley: "The uncritical citation of disputed data by a writer, whether it be deliberate or not, is a serious matter. Of course, knowingly propagandizing unsubstantiated claims is particularly abhorrent, but just as many naïve students may be swayed by unfounded assertions presented by a writer who is unaware of the criticisms.

If the Veterans Administration (VA) health care system could be kept from becoming the world's worst health maintenance organization (HMO), could it serve as an expanded Public Health Service? A number of ominous signs suggest that the VA health care system may not exist much longer. Its aging patient population, 50 percent of whom are World War II and Korean War veterans, will never be replaced, because nuclear weapons have made large standing armies obsolete. And the 90 percent of Vietnam-er

Date: July 6, 1998Cumulative Impact Factors In the February 2, 1998 issue of The Scientist (12[3]:11-12), we published the list of the 100 highest-impact journals for the period 1981-95. This study emphasized long-term cumulative impact rather than short-term or current impact. The main focus of these data were the articles published in 1981-82. We chose these two years so that 15 years of cumulative citations could be compiled. To many of our readers, these years must seem remote. But for some

Big Pharma: Big markets. Traditional science. Big future and lofty salaries. Biotech: Lots of competition for smaller markets. Cutting-edge science. Iffy future, but tempting stock options. Such are the widely held perceptions regarding the industry sectors that employ life science researchers. Those perceptions have become clichés, and like all great clichés, they're not altogether accurate--but they do contain a kernel of truth. The real truth is, the maturing biotech industr
