MEDICAL ROBOTS HAVE BEEN USED TO LOCATE hard-to-find tumors and guide a surgeon's scalpel but have never actually performed surgery on people -- at least not in the U.S. Now that line has been crossed. At Sacramento's Sutter General Hospital, a 90-kg (200 lbs.) machine called Robodoc has operated on its first human patient: a 64-year-old man with...
...animal appeared to have some doglike features. But more and more sightings took place. Rangers and visitors reported seeing paw prints and even groups of wolves. Then on Sept. 30, a hunter's smoking gun left the most compelling evidence thus far: the body of a gray-black 42-kg (92-lb.) male that was shot while supposedly traveling with a group of three or four animals just south of the park in the Teton Wilderness Area. The first scientists on the scene said it looked like a wolf, but U.S. Fish and Wildlife Service experts are putting the remains...
...broad portrait of the Iceman and his times is gradually emerging from the tests and observations. He was a fit man, between 25 and 35, about 1.6 m (5 ft. 2 in.) tall -- which was short even in his day -- and weighed around 50 kg (110 lbs.).

"There were 30 to 40 such explosions," the Gander fire chief reported. Later, live rocket rounds were found among the wreckage, as was an 80-lb. (32-kg) duffel bag stuffed with U.S. currency...
Salmon lovers call completion of Grand Coulee Dam in 1941 one of the darkest moments for the fish. As 27-kg (60-lb.) "June hogs" made their summer migration upstream that year, following their unwavering instinct to return to the streams where they were born, thousands perished when they flung themselves against the unyielding concrete. But even the staunchest fish advocates realize that the June hogs are gone forever and the dams are here to stay. Biologists are optimistic, however, that a strong recovery plan can bring other salmon species back from the brink within 20 years. Leslie Clark...
