...about what's going on behind closed lab doors, if the current congressional ban continues and stem-cell research remains almost entirely in the hands of biotech companies. "That's actually the worst-case scenario because now the public has no input," says Larry Goldstein, a cell biologist at University of California at San Diego. "Companies have to be motivated by profit, so they aren't necessarily going to tell us what they're doing...
...largest remaining cheetah population--about 3,000--inhabits the harshly beautiful savannah of Namibia in southwest Africa. That's where conservation biologist Laurie Marker, founder of the Cheetah Conservation Fund, hopes to ensure the great cat's survival. She sees it as a test case of whether human development and wildlife habitats can coexist. "If we can save the cheetah here," says Marker, "we are talking about saving an entire ecosystem. We can save the world...
Called the "Paul Revere of ecology" and featured in a 1970 Time cover story, Brooklyn-born biologist Barry Commoner was one of the first scientists to worry about a deteriorating environment; he established a pioneering ecological center at Washington University in St. Louis in 1966. A maverick in his science--he didn't initially accept DNA as heredity's master molecule--and a polemical writer (Science and Survival, The Closing Circle), he won 200,000 votes in the 1980 presidential race on the eco-based Citizens' Party ticket. At 82, he remains an active warrior for the environment...
...always exciting for a biologist to find an animal species for the first time, but the 1974 discovery made by Michael Tyler of the University of Adelaide was even more fascinating than usual. Searching a boulder-strewn, fast-flowing creek in an Australian rain forest, Tyler spotted a frog unlike any he'd ever encountered. While its appearance--brown back and cream-colored underside--was nothing special, its reproductive behavior proved to be downright bizarre. The female swallowed her own eggs, incubated them in her stomach and gave birth through her mouth. A single mother coughed up 21 offspring...
...angry, irritable and aggressive than men who had normal to high-normal levels of testosterone. When their testosterone was increased during hormone-replacement therapy, their anger diminished and their sense of well-being increased. "Testosterone is probably a vastly overrated hormone," says Robert Sapolsky, a Stanford University biologist and author of The Trouble with Testosterone...
