Scientists discover an on/off switch for aging cells
(Medical Xpress)—Scientists at the Salk Institute have discovered an on-and-off "switch" in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age.

Solar-cell efficiency improved with new polymer devices
New light has been shed on solar power generation using devices made with polymers. Researchers identified a new polymer -- a type of large molecule that forms plastics and other familiar materials -- which improved the efficiency of solar cells. The group also determined the method by which the polymer improved the cells' efficiency. The polymer allowed electrical charges to move more easily throughout the cell, boosting the production of electricity -- a mechanism never before demonstrated in such devices.

Climate Change: Dwindling wind may tip predator-prey balance
Rising temperatures and shifting precipitation patterns may get the lion’s share of our climate change attention, but predators may want to give some thought to wind, according to a zoologist’s study, which is among the first to demonstrate the way “global stilling” may alter predator-prey relationships.
