"Certain trees are able to clone themselves, which raises the tantalising possibility that they could effectively "live forever". But a study published in the journal PLoS Biology has dashed that hope. "

"Break down the oil slick, keep it off the shores: that's grounds for pumping toxic dispersant into the Gulf, say clean-up overseers. Susan Shaw shows evidence it's sparing some beaches only at devastating cost to the health of the deep sea. "

The Physics Factbook™ is an encyclopedia of scientific essays written by high school students that can be used by anybody. It is an exercise in library research methods in which students are sent out in search of a measurement with the intent of having them find more than just a number with a unit. It is an ongoing project with no foreseeable end date or limits.

The criminal brain has always held a fascination for James Fallon. For nearly 20 years, the neuroscientist at the University of California-Irvine has studied the brains of psychopaths. He studies the biological basis for behavior, and one of his specialties is to try to figure out how a killer's brain differs from yours and mine.

Based on recently revised estimates, BP's ruptured oil well at the bottom of the Gulf of Mexico continues to leak 25,000 to 30,000 barrels of oil a day. The new figures suggest that an amount of oil equivalent to the Exxon Valdez disaster could still be flowing into the Gulf of Mexico every 8 to 10 days. Despite apparent efforts to restrict journalists from accessing affected areas, stories, video and photographs continue to emerge. Collected here are recent photographs of oil-affected wildlife, people and shorelines around the Gulf of Mexico on this, the 51st day after the initial explosion.
