More than six years after it was completed, Oak Ridge National Labs Holifield tandem accelerator has finally reached its design voltage of 25 million volts. The long-awaited event, which took place last month, marked the end of a troublesome startup for the experimental facility, which was designed to conduct experiments involving heavy ions. A sparking “acceleration tube,” which maintains a vacuum around the ion beam, proved the biggest problem for the $8 million machine. The tube

The National Academy of Sciences, including the Academy of. Engineering and the Institute of Medicine, has had a banner year in Congress. The 100th Congress, whose two-year life ended in October, asked the academies to conduct 20 separate studies, a record number that is double the average for the previous five Congresses. The planned studies, which will examine everything from AIDS to export controls, suggest both a growing faith by Congress in the ability of academy panels to deal comprehensi

After two years of trying, scientists at the Yerkes Regional Primate Center have managed to get a chimpanzee pregnant. And their success, accomplished with sperm that had been frozen, has made it possible for the center to create the world’s first chimpanzee sperm bank. Announced in October, the new bank will enable scientists to systematically preserve the gene pool of the U.S. chimp population—a population that has not received an infusion of new blood since the importation of chi

Court Keeps Lab Open University of California, San Francisco, officials got both good and bad news from the California Supreme Court on December 1. The court ordered the university to prepare a new environmental report for a controversial biomedical laboratory (The Scientist, November 28,1988, page 4), which will further delay its full development. But at the same time, the court rejected charges that the lab would endanger the public, and it allowed a small group of scientists to keep working

Molecular biologists: mark your calendars for 1991. That’s the year BASE Corp. hopes to open a new, $45 million biotechnology lab and pilot plant in the Boston area. Plans for the lab were announced by the North American subsidiary of West Germany’s BASE Group last month. The R&D lab, which will be the chemical giant’s first effort in biotechnology in the U.S., will ultimately employ about 230 people, including 60 scientists. A majority of the staff will be new hires from the

In the new wave of neural network startups (see The Scientist, October 17, page 1), NeuralWare Inc. has distinguished itself from the pack. In October, the magazine Synapse Connection called the company “the sales leader in neural computing products.” And, with between $1 million and $3 million in 1988 sales of its software, the Sewickley, Pa-based firm expects to see a profit—just 21 months after mathematician Casey Klimasauskas and his wife Jane founded it with $90,000 of th

After a five-month hiatus, the biology journal Cell will begin filling new subscriptions next month. The influential publication found itself in the awkward position last summer of turning away potential readers. In its July 29 issue, the magazine ran a full-page ad declaring: “Cell is sold out for 1988!!’ Because a subscription to Cell begins in January and ends in December, mid-year subscribers typically receive months of back issues when they join up. But this year, according to

New Aid For AIDS In an effort to capture more data on the treatment of AIDS patients, the National Institute of Allergy and Infectious Diseases (NIAID) will make $6 million available to community-based physicians via a new project, called the Community Programs for Clinical Research on AIDS. The aim is to broaden the statistical basis for research on the disease by providing researchers, statisticians, and computer services to primary-care physicians who are now treating AIDS patients and othe

EDITORS NOTE: In the issue of September 5. 1988, The Scientist published an editorial by Cornell biologist and historian William Provine, which argued that science and religion are incompatiable. We knew that the essay would be controversial, but we still were'nt quite prepared for the response. We received dozens of letters and phone calls, most of them attacking Provine's insistence that scientists must "check their brains at the church house door." We printed a selection of the letters in t

In his eloquent article, “Scientists, Face It! Science and Religion Are Incompatible,” William Provine raised points that have troubled many thoughtful scientists who find themselves unable to reconcile their views about science and religion in an intellectually honest way. He could have raised other compelling arguments against the meaningfulness of our lives, such as the prevalence of horrible human ills and suffering, shared even by innocent infants. In spite of these observati

Back in 1970, our College of Medicine at the University of Iowa was growing rapidly and space was desperately needed. But the dean (and the president) didn’t want just any ordinary science building, so they engaged a nationally known architectural firm in Chicago to design it. The Chicago architects were enthusiastic. Why wouldn’t they be? They’d designed some impressive structures, but they had never designed a science building before. Fortunately, we, the faculty, did not

Of some 69 letters from readers that have been published in The Scientist since our format and editorial changes of last May, over 40% deal with just three subjects: the difficulty of reconciling religion and science (prompted by William Provine’s provocative opinion piece published in our September 5 edition, page 10); the issue of whether to accept rebel or “heretic” scientists who espouse minority views; and the inadequacies of peer review. While this tabulation is admitt

As director of a departmental graduate program, I have found it increasingly difficult to recruit the best American college students for careers in scientific research. I believe that over the past five years, this has become the norm rather than the exception throughout American research universities. Many experts have predicted severe problems for America’s technological future if the trend is not reversed. The tremendous influx and reliance upon the brightest foreign students for grad

In the October 3 issue of The Scientist, you wrote: “Outside reviewers critique a proposal and send...” (page 18). According to my dictionaries there is no verb “to critique.” Hopefully at a future point in time you will eschew such usage!

The anonymous author who argued against the current regime of science prizes (The Scientist, October 17, page 9) makes an interesting case against it, but it is seriously incomplete and thus unscientific. There is no discussion of possible benefits from such a prize system, and nothing in it to show that the costs discussed are so horrendous that no conceivable benefits could outweigh them. The very observation that “science isn’t going to eliminate major prizes” itself sugge

Throughout its entire history, physics seems to have never before experienced a boom similar to that brought on by the higher temperature discovery of Bednon and Müller in 1986. Thousands of researchers throughout the world are now striving to outreach one another, conducting hundreds of experiments, solving innumerable equations, and publishing thousands of papers. Alongside academies and universities, government agencies are also discussing superconductivity problems. What has happened o

Last time we looked at a list of a single year’s most-cited papers (The Scientist, June 27, 1988, page 19), the top 10 represented genetics, biochemistry, immunology, superconductivity, theoretical physics, and clinical medicine—and they were published in a variety of journals. That was for the year 1986. For the year 1987, however, one field and one journal dominated the top 10: Superconductivity and Physical Review Letters. The accompanying table lists the papers published in 19

Indeed, today’s surgery increasingly requires practitioners to keep abreast of countless scientific developments ranging from new drug therapies used in conjunction with a procedure to new applications of high-tech instruments. Some of these innovative therapies and techniques turned

Five years ago, Bruce Culver had what seemed like a good job. Trained as a chemist, he had worked his way up the corporate ladder to become vice president for Applied Research Laboratories in Valencia, Calif. He was tired of the revolving door at the top that had brought in four different company presidents in five years, but he felt pretty secure and had no plans to leave. Then in June 1983, everything changed. The company’s president became the leader of a leveraged buyout. Culver wa

Today’s starting salaries, however, have not yet returned to the far more robust levels of the late 1960s and early 1970s. The high point of salaries for new doctorates caine in 1970 for academia and industry ($30,800 and $47,600 as expressed in 1987 dollars) and in 1965 for government ($43,000). In discussing that era, mathematician Edward Connors, who tracks salaries for the AMS, cites a generally booming economy and an expansionist mood that swept universities, leading to new Ph.D. pr

The urge to start a science journal strikes often—often enough, if stretched out over the course of a year, for one to be launched every working day and most Saturdays as well. In 1987, according to the Institute for Scientific Information’s Current Contents selection staff, at least 302 new science publications first saw the light of day. The staff says “at least” on the presumption that there were some that they didn’t see. Many of these new ventures, of course,

State governments are still willing to pour millions into encouraging high-tech industry, but they’re spending that money somewhat differently from the way they did two years ago. That was the conclusion of the 1988 survey of state technology programs put out by the Minnesota Department of Trade and Economic Development. For evidence that states are increasingly serious about boosting technology, the survey stall’s acting director Gil Young points to the rising number of states cre

Imagine two scientists working on identical research projects—two astronomers, let’s say, who are both studying paired stars. Each has made a number of observations, and each is ready to do some number crunching. Astronomer Number One loads a statistical analysis program on his PC, and sets the calculations into motion. While this automatic process is going on, he’d like to type some notes, but he can’t—at least not on the same PC—because that machine will

With the scanning electron microscope (SEM), scientists in a range of fields—from biology to materials science to microelectronics—can analyze the surface of objects with a resolution approaching molecular dimensions. Although conceptually developed in the 1940s, the SEM was not put into practical use until the 1960s. Improvements in SEM technology continue with the introduction this year of a device that can image unprepared specimens without contaminating the microscope or charg

Applied Biosystems of Foster City, Calif. has introduced the first commercially available instrument that allows scientists—biochemists, for instance—studying biomolecules to take advantage of the innovative technique of capillary electrophoresis (CE). Basically, the Model 270A CE system is an analytical tool that can separate and identify molecules by differences in charge density. CE promises to complement and, in some cases, improve upon the three standard separation techniques:
