...first known encounter with a buckyball was recorded in 1985 by Richard Smalley, a chemical physicist at Rice University, and Harold Kroto, a British chemist from the University of Sussex who was visiting Smalley's lab. The two scientists were studying what would happen if they heated carbon vapor to about 8,000 degreesC (14,500 degrees F). Unexpectedly, they detected a mysterious new form of carbon. Chemical tests proved two things: 1) the molecules had 60 carbon atoms, and 2) they had no "edges," as chemists call the unpaired electrons that cause atoms to form chemical bonds with...
...rush is on to study the properties of buckyballs and explore their possible uses. Scientists have already concluded that the molecule is remarkably durable. Chemist Robert Whetten of UCLA has fired buckyballs at speeds of 27,000 km/h (17,000 m.p.h.) into miniature walls of graphite and silicon. The sturdy spheres bounced back unharmed...
...candidates who fit the mold of many past Harvard presidents, Medical School geneticist Philip Leder '56 and Harvard chemist Jeremy R. Knowles, were each knocked out for the same reason--lack of administrative experience...
...view from space also offers support for a scientific theory that is becoming the paradigm of the new environmentalism. First proposed by British inventor and chemist James Lovelock, this theory, called the Gaia hypothesis, argues that the earth functions as an organism and that life processes regulate the planet to maintain its habitability. According to Gaia, no single species, not even humanity, is necessary to the functioning of the biosphere...
Before anyone jumps to conclusions, there is probably an innocent explanation for the fact that Stanley Pons has dropped out of sight, hiding his whereabouts from the press and his employers. Granted, the University of Utah chemist has been under pressure since March 1989, when he and British colleague Martin Fleischmann said they had created fusion in a jar. Skeptical scientists doubted that the pair had tamed the sun's power source -- at room temperature. The complaint was not just that they had announced their discovery at a press conference rather than in a scientific journal but also that...
