Climate – and not modern humans – was the cause of the Neanderthal extinction in the Iberian Peninsula. Such is the conclusion of the University of Granada research group RNM 179 - Mineralogy and Geochemistry of sedimentary and metamorphic environments, headed by professor Miguel Ortega Huertas and whose members Francisco José Jiménez Espejo, Francisca Martínez Ruiz and David Gallego Torres work jointly at the department of Mineralogy and Petrology of the University of Granada and the Andalusian Regional Institute of Earth Sciences (CSIC-UGR).

A team of biologists at Yale University and the University of Sheffield discovered anatomical details about the female reproductive tract in waterfowl that indicate that male and female anatomy have co-evolved in a "sexual arms race."

Sleep remains one of the big mysteries in biology. All animals sleep, and people who are deprived of sleep suffer physically, emotionally and intellectually. But nobody knows how sleep restores the brain.

Now, Giulio Tononi, a professor of psychiatry at the University of Wisconsin-Madison School of Medicine and Public Health, has discovered how to stimulate brain waves that characterize the deepest stage of sleep. The discovery could open a new window into the role of sleep in keeping humans healthy, happy and able to learn.

Arctic sea ice is melting at a significantly faster rate than projected by even the most advanced computer models, a new study concludes. The research, by scientists at the National Center for Atmospheric Research (NCAR) and the University of Colorado's National Snow and Ice Data Center (NSIDC), shows that the Arctic's ice cover is retreating more rapidly than estimated by any of the 18 computer models used by the Intergovernmental Panel on Climate Change (IPCC) in preparing its 2007 assessments.

Companies selling food products may need to worry about their goods catching "cooties" by coming in contact with certain other products, such as lard and feminine napkins, in shoppers' carts or on store shelves.

Based on their findings, researchers at Duke University and Arizona State University suggest companies may want to reconsider their packaging and shelf positioning strategies in order to safeguard their brands from offending products.

Of all the things companies worry about when selling food products, catching "cooties" is probably not high on the list. But new research suggests it should be.

If you're a communist dictatorship, the solution for pollution is simple - you ban driving.

They did just that during the Summit of the Forum on China-Africa Cooperation from Nov. 4-6, 2006 and it might be an indicator for what they will do during the 2008 Summer Olympics.

Harvard University researchers Michael B. McElroy, Yuxuan Wang, and K. Folkert Boersma used data from the Dutch-Finnish Ozone Monitoring Instrument (OMI) to assess the impact in more rapid fashion than is usually possible.
