Catching some rays: Organic solar cells make a leap forward Posted: 14 Jun 2012 03:27 PM PDT Organic solar cells are becoming more efficient thanks to a new set of discoveries that alter their behaviors at the electronic level.

Engineers perfecting carbon nanotubes for highly energy-efficient computing Posted: 14 Jun 2012 10:12 AM PDT Carbon nanotubes represent a significant departure from traditional silicon technologies and offer a promising path to solving the challenge of energy efficiency in computer circuits, but they aren't without challenges. Now, engineers have found ways around the challenges to produce the first full-wafer digital logic structures based on carbon nanotubes.

Switchable nano magnets may revolutionize data storage: Magnetism of individual molecules switched Posted: 14 Jun 2012 10:10 AM PDT Using individual molecules instead of electronic or magnetic memory cells would revolutionize data storage technology, as molecular memories could be thousand-fold smaller. Scientists have now taken a big step toward developing such molecular data storage.

Optical displays from water and air Posted: 14 Jun 2012 10:08 AM PDT For many years, scientists have been pursuing ways to mimic the perplexing capability of the lotus leaf to repel water. Lotus leaves hate water so much that droplets effortlessly roll off the surface, keeping it clean from dirt. Now an international team of researchers have come up with an entirely new concept of writing and displaying information on surfaces using simply water.  They exploit the unique way a trapped layer of air behaves on a lotus-inspired dual-structured water-repelling surface immersed under water.

A trick of perspective: Chance alignment mimics a cosmic collision Posted: 14 Jun 2012 06:39 AM PDT The NASA/ESA Hubble Space Telescope has produced a highly detailed image of a pair of overlapping galaxies called NGC 3314. While the two galaxies look as if they are in the midst of a collision, this is in fact a trick of perspective: the two just happen to appear in the same direction from our vantage point.

Cassini sees tropical lakes on Saturn's moon Titan Posted: 14 Jun 2012 05:35 AM PDT NASA's Cassini spacecraft has spied long-standing methane lakes, or puddles, in the "tropics" of Saturn's moon Titan. One of the tropical lakes appears to be about half the size of Utah's Great Salt Lake, with a depth of at least 3 feet (1 meter). The result, which is a new analysis of Cassini data, is unexpected because models had assumed the long-standing bodies of liquid would only exist at the poles.

Virtual sailing gives competitors the edge Posted: 14 Jun 2012 05:27 AM PDT Scientists have shown how virtual simulation can be used to accurately predict how a yacht will behave during a race.

Relocating LEDs from silicon to copper enhances efficiency Posted: 14 Jun 2012 05:26 AM PDT Chinese researchers have succeeded in transferring gallium nitride (GaN) light-emitting diodes (LEDs) grown on a layer of silicon to a layer of copper. In comparison with LEDs on silicon substrates, the light output of LEDs on copper was enhanced by 122 percent.

Researchers 'heal' plasma-damaged semiconductor with treatment of hydrogen radicals Posted: 14 Jun 2012 05:26 AM PDT Researchers have developed and tested a new way to heal defects in gallium nitride (GaN), a highly promising material for a wide range of optical and high-power electronic devices.

New discoveries with language learning robots Posted: 14 Jun 2012 04:49 AM PDT Robots can develop basic language skills through interaction with a human, according to new results.
