August 1991

Gilbert Levin has had sweet dreams for a long time. Levin is the president and founder of Biospherics Inc., a Beltsville, Md.-based environmental and health technology company. For nearly two decades, he has sought a noncaloric sweetener boasting both the bulk of table sugar and the ability to withstand cooking heat--in short, the ultimate food additive. Now he thinks he's found it, in a sugar called tagatose. He and the other Biospherics scientists who have studied the tagatose molecule hope

Attending some scientific conferences can be as frustrating for the career-driven researcher as a stroll through a bookstore is for the book-starved browser. With offerings so vast, one simply may not have the time or the energy to satisfy the intellectual appetite. In the spring of 1990, the advisory committee to the NSF chemistry division decided to conduct its annual meeting a little differently. Instead of devoting one hour to one topic before moving on to another, committee members deci

Clearly established research goals, awards of shorter duration, and vigilance over costs will do the trick, says the agency,s director BETHESDA, Md.--National Institutes of Health director Bernadine Healy hopes to increase by almost 50 percent the total number of grants the agency awards over the next several years. To do it, she says, NIH must trim budget requests by principal investigators and tighten up on indirect costs paid to institutions, manipulate the length of its grants awarded to av

Roger Revelle, a California oceanographer who predicted global warming as early as the 1950s, died July 15 at the age of 82. He was a professor emeritus at the Scripps Institution of Oceanography, University of California, San Diego, at the time of his death. Revelle helped found UC-San Diego in 1960. One of the university's five undergraduate colleges is named Revelle College in his honor. Revelle's career, which spanned nearly 60 years, encompassed a wide range of interests. From 1951 until

Although the timing was a coincidence, the simultaneity of the activities symbolized Kennedy's inability to quell, through personal response, the indirect costs controversy that has plagued the U.S. academic world for the past several months--a controversy that Kennedy and his institution principally precipitated. His peers in academe note that failure even as they give expression to their sympathy. "The events of the past year are a sorry climax to a brilliant career," says Richard Atkinson,

WASHINGTON: On July 29, as Donald Kennedy announced his resignation as president of Stanford University, research institutions throughout the United States were rushing to meet a 5 P.M. deadline to comment on changes in the rules governing how much they can charge for the indirect costs of doing federally funded research. Although the timing was a coincidence, the simultaneity of the activities symbolized Kennedy's inability to quell, through personal response, the indirect costs controversy t

Volume 5, #16The ScientistAugust 19, 1991 LEFT-HANDED SUGAR GETS A FREE RIDE OUT OF YOUR SYSTEM Chemical compounds can exist in forms that are mirror images of each other. Like gloves, they can be either left-handed or right-handed. Sugars are such "handed" molecules. Human digestive enzymes have evolved to act upon right-handed sugar molecules, while often allowing left-handed forms to pass directly through. Both l-tagatose, the left-handed form, and d-tagatose, the right-hand

Volume 5, #16The ScientistAugust 19, 1991 PUT THEM ALL TOGETHER, THEY SPELL CHEMISTRY In the spring of 1990, the advisory committee to the NSF chemistry division decided to conduct its annual meeting a little differently. Instead of devoting one hour to one topic before moving on to another, committee members decided to hold the meeting like a retreat. Says NSF chemistry division director Kenneth Hancock: "We decided to sit back and literally ask where the intellectual frontier

Volume 5, #16The ScientistAugust 19, 1991 WHERE ARE NSF'S CHEMISTRY DOLLARS HEADED This year, the National Science Foundation's chemistry division is asking Congress for a 10 percent increase, or $10 million above FY 1991's $100 million, to offset a trend of the past five years that merely kept the division's budget apace with cost-of-living increases. About half of the increase would be distributed across the board to the organic, inorganic, physical, and analytic subdivision

Editor's Note: Today's academic scientists are being asked more frequently than in the past to defend the value of their research. And the pursuit and acquisition of knowledge, once accepted at face value as positive objectives within a democratic society, are no longer good enough, by themselves, to justify scientific investigations. Politicians and the public now demand to know what they are getting for their money, and the most satisfying answers tend to be couched in terms of economic payo

Why is the United States' population scientifically illiterate? One reason is that our society measures intellectual sophistication by one's knowledge of the arts, history, philosophy, economics, politics, and language, but excuses ignorance of basic scientific facts--such as the difference between a molecule and an atom--and the central role that science has played in bringing about improvements in the quality of life and knowledge that produces objectivity of thought and freedom from supersti

I enjoyed the article on honorary degrees in the June 24 issue of The Scientist [page 1], and I agree with Frederick Kelly of the American Association of University Administrators that honorary degrees given to truly deserving individuals serve to enhance the commencement proceedings and make the event more memorable. This is particularly true for smaller schools. On May 18, Delaware Valley College, a small, private school in eastern Pennsylvania, awarded an honorary Doctor of Science degree

I recently received my first copy of The Scientist (the May 13, 1991, issue), in which I read the article about Forrest Mims III [page 12]. There were a lot of points raised about his raising false issues, being a religious fundamentalist, controlling the content of Scientific American, compromising his knowledge of science in favor of his religious beliefs, and not being able to communicate about science. From the same article, I gathered that Mims has a track record that speaks for itself. I

I would like to provide a note of explanation regarding Marcia Clemmitt's article on scientists- turned-project managers (The Scientist, May 27, 1991, page 1). The production of high-flux neutron beams from steady-state reactors has historically set a very high standard for beam stability and reliability that those of us building the next generation of synchrotron research facilities should try to achieve for the X-ray research community. In my own case, I was trained as a neutron scatterer lo

Volume 5, #16The ScientistAugust 19, 1991 Great Balls O' Carbon It was late on an August evening six years ago that Rice University professor Richard Smalley sat in his kitchen, cutting out shapes from a legal pad and taping them together. He was trying to come up with a model having 60 vertices to represent the 60-carbon molecule which he and his collaborators generated in the lab by laser-vaporizing carbon in helium gas. Chemist Harold Kroto was one of these collaborators. He

Two years ago, the 60-carbon, soccer ball-shaped buckminsterfullerene was just a curiosity for Larry Lewis, a staff chemist at the General Electric Co. Corporate Research & Development center in Schenectady, N.Y. At the time, his interest in the recently identified molecule was restricted to "what if" questions inspired by perusing numerous journal articles about it. He couldn't do any lab work with it, though, Lewis says, because "there wasn't enough of the stuff to do chemistry with." But al

Volume 5, #16The ScientistAugust 19, 1991 BUYING BUCKYBALLS Restaurants succeed because people would rather buy the food than prepare and cook it themselves. The situation may be the same with fullerenes--and that's what a handful of companies are banking on. "You can get nice, pure stuff if you make it yourself, but that route is not without problems. It takes about a week to get 250 milligrams of pure material. So the prices are not out of line at all," says Christopher Foote

Publish or perish. It's a dictum drummed into the heads of scientists from the time they begin their studies. Jobs, grants, and promotions--everything of possible import to the budding academic scientist--hinge, to a great extent, on getting one's research into print. But self-advancement also goes hand-in-hand with the progress of science, for publishing papers is the prime means by which important findings are disseminated within the scientific community. To publish a paper in a journal, wher

Editor's Note: This story, which discusses the salaries of men and women scientists, is the first of a two-part series on the National Science Foundation's Biennial Ph.D. Survey. The second part, which will focus on the salaries of scientists in various ethnic groups, will appear in the Sept. 16, 1991, issue of The Scientist. Reinforcing the widely held belief that women scientists face inequalities in compensation, a recent National Science Foundation survey reveals that female Ph.D. research

Young biomedical scientists will lose a major source of postdoctoral training funds as a result of the decision by the Lucille P. Markey Charitable Trust to terminate its Markey Scholars in Biomedical Science program. The trust, created by the heir to the Calumet Farm horseracing fortune, was established in 1982 with the stipulation that all its funds be distributed by 1997. The trustees decided that its seventh round of scholars, announced in February, would be its last. Since the Scholar Aw

Peptides--the amino acid chains that make up proteins--were long relegated to a sideline of the much larger field of protein chemistry. But over the last few decades, their importance has grown as the understanding of these biological building blocks has become essential to a multitude of sciences, from agriculture to therapeutics to the Human Genome Project. As peptide chemistry continues to make its way into other disciplines, it behooves researchers from these disciplines to gain a basic gro

UC VS DOE Far East to West FASEB Attracts Two Societies The Infinite Voyage Part, V The Rat Next Door A few months ago, some University of California officials hinted that the UC system's 45-year stint as caretaker of the Energy Department's national labs could come to an end if DOE officials carried out a plan to open the negotiations to other bidders on soon-to-expire contracts for running the labs. The potential crisis passed, however, as DOE announced it would be negotiating exclus
