China's groundwater irrigation system is responsible for polluting the atmosphere with more than 30 million tonnes of CO2 per year – according to research from the University of East Anglia.

Rats match humans in decision-making that involves combining different sensory cues

Posted: 13 Mar 2012 04:00 PM PDT

The next time you set a trap for that rat running around in your basement, here's something to consider: you are going up against an opponent whose ability to assess the situation and make decisions is statistically just as good as yours. A new study has found that just like humans, rodents also combine multisensory information and exploit it in a "statistically optimal" way -- or the most efficient and unbiased way possible.

Flying through a geomagnetic storm

Glowing green and red, shimmering hypnotically across the night sky, the aurora borealis is a wonder to behold. Longtime sky watchers say it is the greatest show on Earth. It might be the greatest show in Earth orbit, too. High above our planet, astronauts onboard the International Space Station (ISS) have been enjoying an up-close view of auroras outside their windows as the ISS flys through geomagnetic storms.

Input of iron linked to biological productivity in ancient Pacific Ocean

Posted: 13 Mar 2012 11:04 AM PDT

Scientists have found compelling evidence from marine sediment that supports the theory that iron in the Earth's oceans has a direct impact on biological productivity, potentially affecting the amount of carbon dioxide in the atmosphere and, in turn, atmospheric temperature.

Data support theory on location of lost Leonardo da Vinci painting
