People usually have good reasons for swallowing over-the-counter painkillers: They're hurting. But though the drugs often help, new research suggests that they sometimes do the opposite of what their users intended. That's especially true for serious athletes, for whom pain ? and painkillers ? are regular companions. In recent years, scientists have been studying runners competing in the Western States Endurance Run, a 100-mile race through California's Sierra Nevada mountains that involves more than 18,000 total feet of uphill climbing, more than 21,000 feet of downhill running and an average of 26 hours to complete.

When UCLA neuroscientist J. David Jentsch was a grad student, he never expected his life as an academic would require around-the-clock armed guards, or a closed-circuit TV inside his bedroom so he could keep constant watch over his home. But the high-powered security proved necessary again this month when the researcher, who experiments on monkeys, opened a letter left in his mailbox to discover razor blades and a death threat. "We follow you on campus," Jentsch recalled the note reading.

For eight weeks, M56 moved relentlessly, guided by a primordial compass. He covered more than 100 miles and climbed from sea level to a mile high. He traversed saw-toothed mountains, navigated busy highways and furtively skirted suburban neighborhoods. The 20-month-old mountain lion, wearing a tracking collar affixed by UC Davis researchers, left his mother in the foothills of Orange County in early March and struck out on his own. He traveled south through Camp Pendleton, then turned east toward the high country of eastern San Diego County, which opens on the horizon like a centerfold in a coffee table book.

Concerns about the chemical bisphenol A and its potential health risks have led many consumers to be more careful about the containers they use to carry drinking water and feed their babies. The market has responded with water bottles labeled "BPA-free. " And then, in late July, the Environmental Working Group, an advocacy organization, reported that high amounts of BPA are present in everyday cash register receipts, as much as 3% of the total weight of the receipt. Certainly, there would be real concerns if the bisphenol A on receipts readily sloughs off onto the fingers of cashiers and buyers, penetrates several layers of skin and enters the bloodstream at potentially toxic levels, says Kristina Thayer, a scientist at the National Toxicology Program, an interagency group charged with evaluating toxic chemicals.

Watch out, little white lab mouse. Barnyard animals are gunning for your job. A bullish group of agricultural scientists says that farm animals have been vastly underrated as a resource for improving human health -- and they're vying for some of the billions of dollars the government invests in biomedical research. The human-sized hearts and blood vessels of pigs are well-suited for the study of cardiovascular disease, they say.

Led by a professor whose car was set on fire last month in an anonymous attack, more than 400 UCLA scientists and their supporters rallied on campus Wednesday to defend research using animals and to protest the violent tactics of some opponents. At almost the same time, about 40 critics of animal research demonstrated just across Westwood Boulevard from the pro-research gathering, and the two groups briefly traded slogans before marching to different UCLA plazas.
