Environmental scientists have used a very high-resolution computer model to forecast the impact of climate change on US wine and corn production. The experiment focuses on the regional impact of climate change on agriculture in the United States over the next three decades, from wine grapes on the West Coast to maple syrup in the Northeast.
Woolly mammoths and ancient horses may have survived longer than scientists currently think, according to new research on ancient DNA fragments found in Alaskan soil samples.
When the next big earthquake strikes Indonesia, a tsunami could follow close behind, killing thousands of people stuck in traffic jams while attempting to evacuate. Researchers suggest lives can be saved if those residents take refuge instead in nearby tall buildings -- but only after those buildings are strengthened to withstand big waves.
The first article on proton collisions in the CERN Large Hadron Collider -- designed to provide the highest energy ever explored with particle accelerators -- has just been published. In November 2009, during the early commissioning of the LHC, two counter-rotating proton bunches were circulated concurrently for the first time in the machine.

A new study has found that holiday decorations, particularly glass ornaments, are one more safety hazard parents must consider during the season.
Drinking more coffee (regular or decaffeinated) or tea appears to lower the risk of developing type 2 diabetes, according to a new analysis.
A new discovery could contribute to the development of systems that use domestic or agricultural waste to generate clean electricity.
