...UCLA geochemist Frank Kyte thinks he may have found not just the answer but also a piece of the thing itself: a tiny meteorite fragment, a tenth of an inch across, that was extracted from a 65-million-year-old geological layer under more than 50 yds. of sediment at the bottom of the Northern Pacific. In a report in the current issue of Nature, Kyte notes that the little chunk contains concentrations of metals (such as iridium and nickel) and mineral textures that clearly show that it is extraterrestrial and that it probably was once part of a much...

"When I took it home and put it on the kitchen table," says Everett Gibson Jr., a geochemist at the Johnson Space Center, "my wife, who is a biologist, asked, 'What are these bacteria...
Most scientists lean heavily toward the less disturbing theory that life arises spontaneously through commonplace chemical reactions. New findings over the past decade tend to support that idea. "Today life occurs on Earth everywhere you look," says Washington University geochemist Everett Shock. "It's in the Antarctic ice sheet. It's in hot springs. It's buried deep in the sea floor.

Williams was felled as well, but managed to drag himself to partial shelter behind a huge rock...
