...pretrial incarceration without an opportunity for bail. Some experts are also worried that Noriega's lawyers haven't fully explored his POW status or the jurisdictional question of kidnapping him and bringing him to Miami to trial. "How would we feel about Libyan squads coming to the U.S. to extract Islamic justice?" wonders Alfred Rubin, professor of international law at Tufts University...
EVOLUTIONARY BIOLOGY. Thanks to PCR, it is now possible to extract badly degraded DNA sequences from ancient sources and enlarge them like photographic prints. Thus far, PCR has been used to examine minuscule fragments of DNA taken from the brain cells of humans buried 8,000 years ago in a Florida bog. Analysis of such DNA can shed light on the emigration patterns of ancient peoples and perhaps some of the diseases that afflicted them. The technique has also been used to examine DNA from animal skins in natural-history museums and from the frozen remains of woolly mammoths. Among...
...passengers. Tourist buses wheezed desperately up the mountain roads. Near the Turkish border, a tall, eagle-faced man strapped 14 members of his family -- including seven children, his wife and his grandmother -- and innumerable pots, kettles, basins and chicken coops to a huge John Deere tractor. As he helped extract the car of a Western journalist mired in a bog, he spat out a complaint: "Why? Why do you Americans allow this to happen? Saddam will kill us all -- men, women and children. Why doesn't Bush do something? Why should all my children...
Humans have found many uses for the shark, aside from putting it on the dinner table. An extract of its cartilage can serve as a temporary skin for burn victims, and shark corneas have been transplanted into human eyes. Because sharks rarely develop tumors, their immune systems are being studied for anticancer agents. In addition, by preying on sick and injured fish, sharks "help keep the ocean healthy," says Manire. Some biologists believe the rise in stingrays off the Florida panhandle may be a by-product of the shark's decline. Thus an ocean without sharks might be a safer...
Ingber, along with Folkman and their associates, sent the corrupted sample to Japan, where chemists grew the fungus in huge 10,000-liter vats in order to extract the potent compound. The Japanese found the active, capillary-suppressing agent to be the rare fungus fumagillin...
