LONDON (Reuters) - An ancient flood some say could be the origin of the story of Noah's Ark may have helped the spread of agriculture in Europe 8,300 years ago by scattering the continent's earliest farmers, researchers said on Sunday.

Using radiocarbon dating and archaeological evidence, a British team showed the collapse of the North American ice sheet, which raised global sea levels by as much as 1.4 meters, displaced tens of thousands of people in southeastern Europe who carried farming skills to their new homes.

The researchers said in the journal Qua

Washington, D.C., – Conservation groups Oceana and the Center for Biological Diversity petitioned the federal government today to stop the precipitous decline of the western North Atlantic loggerhead sea turtle.

VALENCIA, Spain (Reuters) - Delegates at crucial U.N. talks on the causes and effects of global climate change are making slow progress with an agreement still some way off, sources close to the discussions said on Thursday.

"The same governments which are usually hostile to binding emissions reductions, and especially the Kyoto Protocol, are also those who are blocking progress on agreeing to sound science as the basis for future action," said Stephan Singer, a climate expert at the WWF conservation group.

Yellowstone Viruses 'Jump' Between Hot Pools
November 15, 2007 09:36 AM - INL

A population study of microbes in Yellowstone National Park hot pools suggests viruses might be buoyed by steam to distant pools. The result, to be published online next week in the Proceedings of the National Academy of Sciences, could help to answer some fundamental questions about how microbes, and the viruses that infect them, impact their environment.

NASA Sees Arctic Ocean Circulation Do an About-Face

PASADENA, Calif. – A team of NASA and university scientists has detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric circulation changes that vary on decade-long time scales. The results suggest not all the large changes seen in Arctic climate in recent years are a result of long-term trends associated with global warming.

Small Planets Forming in the Pleiades: Astronomers
November 15, 2007 09:06 AM - Reuters

WASHINGTON (Reuters) - Small, rocky planets that could resemble the Earth or Mars may be forming around a star in the Pleiades star cluster, astronomers reported on Wednesday.

One of the stars in the cluster, also known as the Seven Sisters, is surrounded by an extraordinary number of hot dust particles that could be the "building blocks of planets" said Inseok Song, a staff scientist at NASA's Spitzer Science Center at the California Institute of Technology.
