Stepping out in style: Toward an artificial leg with a natural gait Posted: 14 Oct 2013 12:57 PM PDT Humans rarely walk the straight and narrow; something's always in the way. So scientists are developing a computer-controlled artificial limb that can turn like a flesh-and-blood foot.

A blueprint for restoring touch with a prosthetic hand Posted: 14 Oct 2013 12:56 PM PDT New research is laying the groundwork for touch-sensitive prosthetic limbs that one day could convey real-time sensory information to amputees via a direct interface with the brain.

Adhesion at 180,000 frames per second: Widespread natural adhesion system unraveled Posted: 14 Oct 2013 06:41 AM PDT Adhesion is an extremely important factor in living nature: insects can climb up walls, plants can twine up them, and cells are able to adhere to surfaces. During evolution, many of them developed mushroom-shaped adhesive structures and organs. Scientists have now discovered why the specific shape is advantageous for adhesion. The answer is in homogeneous stress distribution between a surface and the adhesive element.

2013 Nobel Prize in Economics: Trendspotting in asset markets Posted: 14 Oct 2013 05:21 AM PDT The Royal Swedish Academy of Sciences has decided to award The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for 2013 to Eugene F. Fama of the University of Chicago, IL, USA; Lars Peter Hansen of the University of Chicago, IL, USA; and Robert J. Shiller of Yale University, New Haven, CT, USA "for their empirical analysis of asset prices."

Light's improbable connection mapped: Ultrafast laser pulses could control quantum properties of light Posted: 11 Oct 2013 06:25 AM PDT Quantum optics scientists and engineers are striving to harness the properties of small packets of light called photons to improve communications and computational devices. Vital to these efforts is an invisible connection between pairs of photons; understanding this effect is therefore crucial. By mapping the connections, researchers have shown that the properties of each photon in a pair, which were created in the same time and place, are governed by statistics1. The maps could aid future quantum optics engineering efforts.

Progress with the switch to faster computers Posted: 11 Oct 2013 06:25 AM PDT A specialized switch that controls light can regulate the flow of optical data at a speed suitable to accelerate computers.

Simpler route to hollow carbon spheres Posted: 11 Oct 2013 06:25 AM PDT Microporous walls and a huge surface area help nanoparticles to boost lithium-ion battery performance.

Security comparison: Android versus Apple Posted: 11 Oct 2013 06:25 AM PDT A large study of smartphone applications provides a baseline for comparing the security of different mobile providers.
