New Geology study raises questions about long-held theories of human evolution
2013-01-31 11:00:00| LifeSciencesWorld
[NEWS] Contact: Robert Perkins perkinsr@usc.edu 213-740-9226 University of Southern California What came first: the bipedal human ancestor or the grassland encroaching on the forest? A new analysis of the past 12 million years' of vegetation change in the cradle of humanity is challenging long-held beliefs about the world in which our ancestors …

Evolution inspires more efficient solar cell design
2013-01-25 18:17:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The sun's energy is virtually limitless, but harnessing its electricity with today's single-crystal silicon solar cells is extremely expensive -- 10 times pricier than coal, according to some estimates. Organic solar cells -- polymer solar cells that use organic materials to absorb light and convert it into electricity -- could be a solution, but current designs suffer because polymers have less-than-optimal electrical properties. Researchers at Northwestern University have now developed a new...
