Nanotechnology Pioneer Slays 'Grey Goo' Myths - SpaceDaily  Eric Drexler, known as the father of nanotechnology, published Wednesday a paper that admits that self-replicating machines are not vital for large-scale molecular manufacture, and that nanotechnology-based fabrication can be thoroughly non-biological and inherently safe. Talk of runaway self-replicating machines, or "grey goo", which he first cautioned against in his book Engines of Creation in 1986, has spurred fears that have long hampered rational public debate about nanotechnology. "Runaway replicators cannot be built with today's nanotechnology toolset," says Dr. Drexler
NASA Data Shows Deforestation Affects Climate In The Amazon - SpaceDaily  NASA satellite data are giving scientists insight into how large-scale deforestation in the Amazon Basin in South America is affecting regional climate. Researchers found during the Amazon dry season last August, there was a distinct pattern of higher rainfall and warmer temperatures over deforested regions. "In deforested areas, the land heats up faster and reaches a higher temperature, leading to localized upward motions that enhance the formation of clouds and ultimately produce more rainfall," Negri said.  

Oldest Antarctic Ice Core Reveals Climate History  - SpaceDaily  Secrets of the Earth's past climate locked in a three-kilometre long Antarctic ice core are revealed this week in the journal Nature. The core from Dome C, high on East Antarctica's plateau, contains snowfall from the last 740,000 years and is by far the oldest continuous climate record obtained from ice cores so far. The first results confirm that over the last 740,000 years the Earth experienced eight ice ages, when Earth's climate was much colder than today, and eight warmer periods (interglacials). In the last 400,000 years the warm periods have had a temperature similar to that of today. Before that time they were less warm, but lasted longer.
