| Evidence of past Southern hemisphere rainfall cycles related to Antarctic temperatures Posted: 17 Jan 2012 01:16 PM PST Geoscientists have published the first evidence that warm-cold climate oscillations well known in the Northern Hemisphere over the most recent glacial period also appear as tropical rainfall variations in the Amazon Basin of South America. It is the first clear expression of these cycles in the Southern hemisphere.  |
| Fruit flies watch the sky to stay on course Posted: 17 Jan 2012 01:14 PM PST New research demonstrates that fruit flies keep their bearings by using the polarization pattern of natural skylight, bolstering the belief that many, if not all, insects have that capability.  |
| Posted: 17 Jan 2012 01:14 PM PST Data from end of the last Ice Age confirm effects of climate change on oceans The first comprehensive study of changes in the oxygenation of oceans at the end of the last Ice Age (between about 10 to 20,000 years ago) has implications for the future of our oceans under global warming.  |
| Ten-second dance of electrons is step toward exotic new computers Posted: 17 Jan 2012 11:52 AM PST Scientists have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum computers.  |
| Biologists replicate key evolutionary step Posted: 17 Jan 2012 11:43 AM PST More than 500 million years ago, single-celled organisms on the Earth's surface began forming multicellular clusters that ultimately became plants and animals. Just how that happened is a question that has eluded evolutionary biologists.  |
