Touch-Based Interfaces on Everyday Surfaces

Researchers at Carnegie Mellon University (CMU) have demonstrated how a depth camera system such as Microsoft’s Kinect can create touch-based interfaces almost at will, with the wave of a hand. CMU’s WorldKit system enables someone to rub the arm of a sofa to “paint” a remote control for her TV, or swipe a hand across an office door to post his calendar from which subsequent users can “pull down” an extended version. These ad hoc interfaces can be moved, modified or deleted with similar gestures, making them highly personalized.

Curiosity Update

Mars has lost much of its original atmosphere, but what’s left remains quite active, according to NASA’s Mars rover Curiosity. Evidence has strengthened that Mars lost much of its original atmosphere by a process of gas escaping from the top of the atmosphere. Watch Tech Briefs TV for the latest videos of the mission at www.techbriefs.com/tv/mars. Keep up with Curiosity at http://mars.jpl.nasa.gov/msl.

Registration Opens for Energy Challenge

Registration is open for teams seeking to compete in the $1.5 million energy storage competition known as the Night Rover Challenge, sponsored by NASA and the Cleantech Open of Palo Alto, CA. To win, a team must demonstrate a stored energy system that can power a simulated solar-powered exploration vehicle that can operate through multiple cycles of daylight and extended periods of darkness. Registration closes on October 25, 2013. Visit: www.nightrover.org to register.

Research May Unlock Secret of Alzheimer’s

Some of the core beliefs about what causes Alzheimer’s and Parkinson’s diseases may be wrong, and flying an experiment on the International Space Station (ISS) could provide the best way to show it. Scientists at Kennedy Space Center, working with the Florida Institute of Technology (FIT), want to send a set of proteins to the ISS where the material would be free to collect together into large, complex structures without gravity tearing them apart.

Trees Used to Create Recyclable Solar Cells

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells using natural substrates derived from plants such as trees. By fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle.

Curiosity Update

NASA’s Mars rover Curiosity has seen evidence of water-bearing minerals in rocks near where it had already found clay minerals inside a drilled rock. The rover’s science team announced that analysis of powder from a drilled mudstone rock on Mars indicates past environmental conditions that were favorable for microbial life. Watch Tech Briefs TV for the latest videos of the mission at www.techbriefs.com/tv/mars. Keep up with Curiosity at http://mars.jpl.nasa.gov/msl.
