Olfaction Scientists: Sniffing Out Some New Applications
Robin Eisner | Nov 11, 1990 | 9 min read
A wide range of scientific challenges spawns a surge in basic research for this once unacclaimed discipline Most researchers long believed that the sense of smell was genetically determined and, therefore, unchangeable. But at least one scientist--Charles Wysocki of the Monell Chemical Senses Center in Philadelphia--doubted this theory. Wysocki, a psychobiologist who investigates the genetics of olfaction in the 45 percent of the adult population who can't detect androstenone, a component in s

Photo: Steve Bunk Dave Tinnin, field research associate in the University of New Mexico's biology department, takes blood samples and measurements of rodents caught on the research station grounds. At the end of a freeway exit near Soccoro, N.M., the hairpin turn onto a gravel road is marked by a sign that warns, "Wrong Way." But it isn't the wrong way if you want to reach the University of New Mexico's (UNM) long-term ecological research (LTER) station. The sign's subterfuge is the first indi

African Sleeping Sickness: A Recurring Epidemic
Ricki Lewis | May 12, 2002 | 5 min read
African trypanosomiasis is making an unwelcome comeback. But unlike other returning diseases, this one has a drug treatment—eflornithine—that disappeared from the market when it failed to cure cancer. Yet like Viagra's origin from a curious side effect in a clinical trial, so too was eflornithine reborn. "When it was discovered that it removes mustaches in women, it suddenly had a market: western women with mustaches," says Morten Rostrup, president of the international council for M

Researchers Receiving MacArthur Fellowships Demonstrate 'Capacity To Make A Difference'
Bruce Anderson | Sep 14, 1997 | 6 min read
PRIZE WITH A PRICE: Science historian Peter Galison has taken some ribbing from his family since being named a MacArthur fellow. One could almost pity Peter Galison. A historian of science at Harvard University, Galison is one of seven members of the scientific community among the 23 recipients of this year's John D. and Catherine T. MacArthur Foundation Fellowships. The coveted five-year awards provide unrestricted support plus health insurance to talented individuals, with no reports or proj
