Nanowire solar cells raise efficiency limit

Posted: 24 Mar 2013 12:23 PM PDT

Scientists have shown that a single nanowire can concentrate the sunlight up to 15 times of the normal sun light intensity. The results are surprising and the potential for developing a new type of highly efficient solar cells is great.

Venus vortices go for chaotic multi-storey strolls around the poles

Posted: 24 Mar 2013 12:21 PM PDT

A detailed study of Venus' South Polar Vortex shows a much more chaotic and unpredictable cyclone than previously thought. The analysis reveals that the center of rotation of the vortex wanders around the pole differently at different altitude levels in the clouds of Venus. In its stroll around the Pole, in layers separated by 20 km, the vortex experiences unpredictable changes in its morphology. The results of this study are published online in Nature Geoscience today.

Paint-on plastic electronics: Aligning polymers for high performance

Posted: 24 Mar 2013 12:18 PM PDT

Semiconducting polymers are an unruly bunch, but now engineers have developed a new method for getting them in line that could pave the way for cheaper, greener, "paint-on" plastic electronics.
