Although few restoration projects are more than a decade old, many have already begun to generate encouraging results. In Costa Rica, University of Pennsylvania biologist Daniel Janzen is helping rebuild a nearly extinct tropical dry forest in the 110,000-hectare (272,000-acre) Guanacaste Conservation Area, which until five years ago had been overrun by cattle and torched annually by ranchers and hunters. In California, at the Nature Conservancy's Coachella Valley Preserve, a few dozen volunteers felled thousands of salt cedar trees that had sucked this small desert area nearly dry, clearing the way for the reappearance...
...ways, diseases and droughts have more impact than they would if planters grew a diverse array of crops. Senator Albert Gore of Tennessee is convinced that the decline of diversity is one of the greatest threats facing world agriculture. "We may see a significant number of crops become functionally extinct," he says, "enjoying bumper crops until one day the hammer falls in the form of a blight they cannot handle...
...date, PCR has been used to compare the DNA of extinct animals with their closest living relatives. It has assisted the U.S. military in identifying the remains of soldiers who died during Operation Desert Storm. It is beginning to help physicians detect small numbers of cancer cells circulating in the bloodstream and make prenatal diagnoses of genetic diseases such as sickle- cell anemia, as well as ensure better matches between organ donors and transplant recipients...
BABE. You thought the breed was extinct, that the only female body fashion was the sculpted, sanded sylph. Then along came Jennifer Connelly, innocent of face, voluptuous of form, aerodynamically perfect.

Film critics quickly add that she is an appealing actress, just as men once declared that they read Playboy for the interviews. But so far Connelly has been mainly calendar art: Bettie Page via Vargas, a body without a soul. Moviemakers...
...evidence mounts, more researchers are convinced that the Chicxulub crater marks the impact point of the killer comet. Says Boynton: "This is nearly as close to a certainty as one can get in science." Some scientists disagree. David Archibald, a biologist at San Diego State University, believes the extinctions took place more gradually and in a complex pattern. "There is zero evidence that dinosaurs became extinct virtually overnight...
