Scientists have begun to think of possible uses for adaptive, self- replicating machines -- cleaning up toxic wastes, perhaps, or exploring outer space. There is a danger, though, that such machines could multiply uncontrollably, like the viruses that have disrupted computer networks. Doyne Farmer, a physicist at the Los Alamos lab, points to a cautionary science- fiction tale by Stanislaw Lem. In Lem's Fiasco, space explorers discover a Saturn-like planet with a ring around it. On closer inspection, the ring turns out to be a swarm of attack satellites and killer robots, part of a "star wars" defense shield...
Only one event brightened an otherwise gloomy week for the space agency. The first commercial version of the Atlas rocket was finally launched by NASA from Cape Canaveral. It lofted into orbit a satellite that in September will provide scientists with important data on radioactive damage to satellites in outer space...
NONETHELESS, our hero shouldn't just walk away from this fight. The Senate should make Souter answer some questions: questions about his basic philosophies for constitutional interpretation, so that it may, in the words of one legal scholar, "police the outer limits" and "preserve the balance" of the court. That is how it stopped Robert Bork, and that is how it can stop David Souter, if such a rejection is called...
...this year the moguls spent $55 million to send Tom Cruise around a racetrack in Days of Thunder, $65 million to launch Arnold Schwarzenegger into outer space for Total Recall, $70 million to help Bruce Willis save a besieged airport in Die Hard 2. The industry would pay any price, detonate any explosion, inflate any body count to meet its megahit expectations...
...skin's dynamic outer layer, or epidermis, serves as the staging ground for all three of the major skin cancers. Both basal-cell and squamous-cell carcinomas arise from the most common skin cells, the keratinocytes, which form at the base of the epidermis and work their way toward the surface. Near the base, they are plump and are called basal cells. But as they move outward, they flatten to become the squamous cells that form the skin's tough, protective surface. Melanomas spring from melanocytes, cells that produce pigment...
