Topological insulators: Breaking symmetry for faster computers Posted: 24 Nov 2013 08:18 PM PST A new compound shows highly unusual conducting properties that could be used in future electronic components.

Scientists develop novel X-ray device: New way to generate synchrotron X-rays Posted: 24 Nov 2013 05:05 PM PST A new laser-driven device could do for research-quality X-rays what the smart phone did for computing.

X-rays reveal another feature of high-temperature superconductivity Posted: 24 Nov 2013 05:05 PM PST Classical and high-temperature superconductors differ hugely in their critical temperature when they lose electrical resistance. Powerful X-rays made possible to establish another big difference: high-temperature superconductivity cannot be accounted for by the mechanism that leads to conventional superconductivity. This is why other scenarios must now be developed to explain high-temperature superconductivity.

X-ray laser can solve protein structures from scratch Posted: 24 Nov 2013 05:05 PM PST A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.

How losing information can benefit quantum computing Posted: 24 Nov 2013 05:05 PM PST Suggesting that quantum computers might benefit from losing some data, physicists have now entangled -- linked the quantum properties of -- two ions by leaking judiciously chosen information to the environment.

Diamond 'flaws' pave way for nanoscale MRI Posted: 24 Nov 2013 05:05 PM PST Breakthrough offers high-sensitivity nanoscale sensors, and could lead to magnetic imaging of neuron activity and thermometry on a single living cell.

A new, flying jellyfish-like machine Posted: 24 Nov 2013 05:00 PM PST Up, up in the sky: It's a bird! It's a plane! It's a . . . jellyfish? That's what researchers have built -- a small vehicle whose flying motion resembles the movements of those boneless, pulsating, water-dwelling creatures. The work demonstrates a new method of flight that could transport miniaturized future robots for surveillance, search-and-rescue, and monitoring of the atmosphere and traffic.

The secrets of owls' near noiseless wings Posted: 24 Nov 2013 06:35 AM PST Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence. A research group is working to solve the mystery of exactly how owls achieve this acoustic stealth -- work that may one day help bring "silent owl technology" to the design of aircraft, wind turbines, and submarines.

The physics of beer tapping Posted: 24 Nov 2013 06:35 AM PST An old, hilarious if somewhat juvenile party trick involves covertly tapping the top of someone's newly opened beer bottle and standing back as the suds foam out onto the floor. Now researchers have produced new insight into the science behind the foaming, exploring the phenomenon of cavitation.
