Hypersonic inflatable heat shield successfully tested Posted: 23 Jul 2012 02:18 PM PDT A large inflatable heat shield developed by NASA's Space Technology Program has successfully survived a trip through Earth's atmosphere while traveling at hypersonic speeds up to 7,600 mph.

Strobe eyewear training improves visual memory Posted: 23 Jul 2012 02:18 PM PDT Participants in a new study engaged in physical activities, such as playing catch, while using either specialized eyewear that limits vision to only brief snapshots or while using eyewear with clear lenses that provides uninterrupted vision. There was an observed boost in their visual memory retention that was found to still be active 24 hours later.

Printed photonic crystal mirrors shrink on-chip lasers down to size Posted: 23 Jul 2012 06:52 AM PDT Electrical engineers have devised a new laser for on-chip optical connections that could give computers a huge boost in speed and energy efficiency.

World's first violet nonpolar vertical-cavity laser technology created Posted: 23 Jul 2012 06:52 AM PDT Researchers have developed the first violet nonpolar vertical-cavity surface-emitting lasers based on m-plane gallium nitride semiconductors.
