Special Report: Where Are Today's Black Scientists?

New Ph.D.'s are at a 10-year low as cultural and educational obstacles keep blacks from careers in science and engineering As ambitions go, Nola Campbell's do not seem grandiose. The senior at Roosevelt High School in Washington, D.C., just wants to get a Ph.D. in chemistry and become a scientist. But the odds are against her, for one simple reason: Campbell is black. The statistics paint a bleak picture of her chances. In 1987 only 222 blacks received Ph.D.s in the sciences and engineering

The New Look Of Euroscience: Mapping Output And Impact

U.K. produces more papers than any other European nation, but articles from Switzerland carry more clout For centuries, the nations of Europe have been competing fiercely with one another. They have fought long and bitter battles over mere slivers of land. They have clashed repeatedly in pursuit of new markets. Fortunately, outright warfare over land and markets is largely a thing of the past. But there is one realm in which the competition, although more civilized, is still hotly contested

Improving The Lot Of The Laboratory Animal

Sidebar: What Can Scientists Do To make Animals 'Happier' Animal rights activists have had an impact, but the biggest changes are coming from scientists themselves Why should a physicist or a chemist care about the endless public debate over the use of research animals? Almost every scientist knows the creatures are crucial for progress in biology and medicine. And scientists are fed up with the clamor being raised by folks who seem to care less about the human animal than about the lab anima

Alan Huang Lights Up Bell's Computers

Some call him a genius, others a charlatan; but even his critics agree that Huang's optical computers are unsurpassed HOLMDEL, N.J.--Absent was the cautious reserve usually adopted by scientists in formal presentations. In its place was Alan Huang's characteristic approach to the scientific briefing: machine-gun bursts of excited speech, highly animated hand gestures, all in support of the virtues of Huang's passion - optical computers, whose circuits run on light rather than electricity.

What Can Scientists Do To Make Animals `Happier'?

The rhesus monkey ambles over to the side of its cage and reaches up to a blue metal box strapped to the bars. With a long finger it touches a metal bar protruding from the box. Five touches . . .10 . . .15 - and a small white pellet rolls out into a slot. The monkey fishes out the banana-flavored snack and pops it into its mouth. Then it presses a second metal bar and the voice of Willie Nelson fills the room: "Mamas, don't let your babies grow up to be cowboys. . ." No, this scene at the Uni

Tales Of Four Blacks In Science

Editor's note: The Scientist talked at length with four black scientists and aspiring researchers about the problems they have faced living in a culture that offers them little or no encouragement to become professional scientists. The individuals stand at vastly different stages of their careers and pursue different fields, and their experiences vary dramatically. But their stories illuminate the problems facing black scientists in the United States, and hint at possible solutions. SHIRLEY JA

Similar ideas appear in the theory of quark confinement and in the theory of fractional statist

Low-Cost Speedup Boards Geared To Perk Up Sluggish PCs

Are you thinking of buying a new computer because your IBM PC or compatible is too slow - and are you also finding it difficult to justify a $3,000 expense just for an increase in processing speed? For those scientists looking for extra speed, but not ready to invest in a new machine, a very practical alternative exists: Add-on cards are available that will speed up any IBM PC or compatible so that it runs even faster than an IBM AT. Commonly called "accelerator cards" or "speedup boards," th

Ever wonder what happens to those bright-eyed science and engineering undergraduates who come to Washington each summer as interns to learn how policy is really made? Well, for at least one recent intern, a summer in Washington led to a high-profile job with the Bush transition team.

Opinion

Scientists Should Be Interested in Cooking

A year or two ago, the most famous science graduate of our age - Prime Minister Margaret Thatcher - appeared on British television, explaining some of the chemistry behind everyday cooking. Most established scientists reacted adversely, claiming that the Iron Lady was just trying to curry political favor with ignorant housewives. Not so long after Thatcher's exercise in culinary science, the professor of one of the largest, oldest, and most prestigious chemistry schools in Britain also appear

Warning: Scientists Are Becoming Too Much Like Chefs

If you have worked or lived in Boston, you know that when you ride the subway to the airport, the final destination of the train you take is Wonderland. It always makes me smile to think that when I go from the airport to one of the great centers of modern science in the world, my train is moving away from Wonderland. Is this just a coincidence of names or is it a prophecy for what is now happening to science? Are we moving from a wonderland where science is fun, a thirst for knowledge and new

Alan Nixon's essay struck in me a sympathetic chord. The issue with which he dealt, the propriety of using data obtained by the Nazis under inhuman conditions, is certainly a provocative one which invites the weighing of moral issues (whether we condone the mode of experimentation) vs. scientific and more important human welfare considerations. I share with Nixon the belief that we cannot undo these dreadful acts of carnage but that we can make amends for them by deriving information of use in

Letters

In the last several years there has been an increasing chorus of voices trying to convince us that there was some good after all in the work of the Nazi scientists who participated in the concentration camp medical experiments. This new breed of apologist claims to have exhumed from among the bones, so to speak, of the holocaust victims some gems of scientific research which will benefit mankind. Alan Nixon's recent essay (The Scientist, November 14, page 9) is the latest contribution in that

The utilization of technology and science by Nazi Germany brought home the truth of the maxim that "knowledge without conscience brings ruin to the soil." The "opinion" by Alan C. Nixon reminds us that this lesson has yet to sink in. The question is raised concerning a recent EPA decision to exclude data on the toxicity of phosgene which was obtained from records of Nazi experiments performed on French "prisoners." Nixon points out that such data might save lives, and asks rhetorically, "are we

Commentary

Citing Nazi `Research':How To Do It, If You Must Elie Wiesel, the concentration camp survivor and 1986 Nobel laureate, has often spoken and written about the difficulty of translating the events of the Holocaust into words. To do so, he has explained, begins to limit and make objective what can neither be, nor should be, easily defined and comfortably separated from our daily lives as just another grim episode in history that happened long ago and here. The Holocaust was qualitatively differen

Critics Rip Agriculture Department's Funding Methods

The United States Department of Agriculture, which ranks sixth among government agencies in science funding, is giving out a respectable amount of research money - $900 million - this year. Less respectable, however, is the way the department will go about doling out the bulk of that money, at least according to two major policy studies by agriculture experts. Among the chief complaints: That the USDA does not use competitive peer reviewed proposals as a basis for the distribution of most of

"There's a perception that what Japan does is import all its technology and turn around and export the products," says Maria Papadakis of the National Science Foundation's International Studies Group. But a recent NSF report on R&D funding that Papadakis authored supports her opinion to the contrary, namely that, in Japan, "there's a lot more innovation than the country is given credit for." The NSF report focuses on how and where Japan spends its R&D dollars, what funding goes to its own scie

Where lab space is at a premium, scientists in environmental analysis, biology, and superconductivity research may want to consider replacing their huge bell-jar vacuum deposition systems with a new desktop model. Balzers' new MED 010 vacuum deposition system is said to provide fast, accurate rotary shadowing of specimens with carbon, a process that gives a better three-dimensional view of a sample for transmission electron microscopy (TEM).
