First virtual surgery with Google Glass Posted: 08 Nov 2013 11:04 AM PST A surgical team has performed the first surgery using a virtual augmented reality technology called VIPAAR in conjunction with Google Glass, a wearable computer with an optical head-mounted display. The combination of the two technologies could be an important step toward the development of useful, practical telemedicine.

Researchers develop at-home 3D video game for stroke patients Posted: 08 Nov 2013 07:21 AM PST Researchers have developed a therapeutic at-home gaming program for stroke patients who experience motor weakness affecting 80 percent of survivors.

NASA's GRAIL mission puts a new face on the moon Posted: 08 Nov 2013 06:17 AM PST Scientists using data from the lunar-orbiting twins of NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission are gaining new insight into how the face of the moon received its rugged good looks.

Robotic advances promise artificial legs that emulate healthy limbs Posted: 08 Nov 2013 06:13 AM PST Recent advances in robotics technology make it possible to create prosthetics that can duplicate the natural movement of human legs. This capability promises to dramatically improve the mobility of lower-limb amputees, allowing them to negotiate stairs and slopes and uneven ground, significantly reducing their risk of falling as well as reducing stress on the rest of their bodies.

It's complicated: Dawn spacecraft spurs rewrite of asteroid Vesta's story Posted: 08 Nov 2013 06:13 AM PST Just when scientists thought they had a tidy theory for how the giant asteroid Vesta formed, a new paper from NASA's Dawn mission suggests the history is more complicated. If Vesta's formation had followed the script for the formation of rocky planets like our own, heat from the interior would have created distinct, separated layers of rock (generally, a core, mantle and crust). In that story, the mineral olivine should concentrate in the mantle. However, that's not what Dawn's visible and infrared mapping spectrometer (VIR) instrument found.

Novel LEDs pave the way to cheaper displays Posted: 08 Nov 2013 06:10 AM PST Researchers have developed a novel type of organic light-emitting diode (OLED). These lights are suitable for the design of particularly energy-efficient cheap displays, which find applications in smart phones, tablet PCs or TVs. Applications in lighting such as in luminescent tiles are also conceivable.

Black holes don't make a big splash Posted: 08 Nov 2013 06:10 AM PST Throughout our universe, tucked inside galaxies far, far away, giant black holes are pairing up and merging. As the massive bodies dance around each other in close embraces, they send out gravitational waves that ripple space and time themselves, even as the waves pass right through our planet Earth. Scientists know these waves, predicted by Albert Einstein's theory of relativity, exist but have yet to directly detect one. In the race to catch the waves, one strategy -- called pulsar-timing arrays -- has reached a milestone not through detecting any gravitational waves, but in revealing new information about the frequency and strength of black hole mergers.
