...within 1.3 miles of a recently sprayed area. The Army had fairly detailed records on the daily positions of its companies during the fighting. There were gaps, but the Pentagon group repeatedly told the CDC that other documents, such as daily journals and situation reports, could be used to pinpoint which units had ventured into areas sprayed with the defoliant. Houk's team complained that the Pentagon data were too spotty to determine whether companies had been deployed in normal formations spread over 200 to 300 yards or dispersed over distances of up to 12 miles.

But even when these helium-inflated giants are trouble-free, on-line agents question their effectiveness. They cannot be flown in bad weather, and the drug activity they pinpoint is often in remote terrain that undermanned law- enforcement agencies must spend hours to reach.

Ever since its development in the 1940s, radiocarbon dating has been a vital tool for historians and paleontologists trying to pinpoint the ages of everything from ancient animal bones to prehistoric human settlements to Egyptian mummies. By measuring the decay of the natural radioactive isotope carbon 14, which almost all organisms ingest while they are alive, scientists can estimate how long it has been since an animal or plant died...

The illness seems to involve some malfunction of the immune system, perhaps triggered by stress, that can allow any number of normally dormant viruses, including Epstein-Barr, herpes VI and even polio-like pathogens, to become active...

With no specific tests to pinpoint the syndrome, patients having milder symptoms can go through several physicians before finding one who believes something is seriously wrong. However, more and more doctors are listening to the complaints and learning to distinguish CFS patients from people with tendencies toward hypochondria and depression...
