Photon collisions: Photonic billiards might be the newest game!
When one snooker ball hits another, both spring away from each other in an elastic manner. In the case of two photons a similar process -- the elastic collision -- has never been observed. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences have shown, however, that such a process does not only occur, but even could soon be registered in heavy ion collisions at the LHC accelerator.

Will more snow over Antarctica offset rising seas? Don't count on it
Heavier snow over Antarctica was supposed to be one of the few brakes on sea-level rise in a warming world. But that prediction is not reliable, says a new study of Antarctic snowfall over the past 31,000 years.

Scientists discover the evolutionary link between protein structure and function
A new University of Illinois study demonstrates the evolution of protein structure and function over 3.8 billion years. Snippets of genetic code, consistent across organisms and time, direct proteins to create 'loops,' or active sites that give proteins their function. The link between structure and function in proteins can be thought of as a network. Demonstrating evolution in this small-scale network may help others understand how other networks, such as the internet, change over time.

Robots get creative to cut through clutter
Clutter is a special challenge for robots, but new Carnegie Mellon University software is helping robots cope, whether they're beating a path across the moon or grabbing a milk jug from the back of the refrigerator. The software not only helped a robot deal efficiently with clutter, it surprisingly revealed the robot's creativity in solving problems.

How viruses infect bacteria: A tale of a tail
Bacteriophages are viruses that infect bacteria. Using state-of-the-art tools, EPFL scientists have described a million-atom 'tail' that bacteriophages use to breach bacterial surfaces. The breakthrough has major implications for science and medicine, as bacteriophages are widely used in research.

UC geologists identify sources of methane, greenhouse gas, in Ohio, Colorado and Texas
Methane comes from various sources, like landfills, bacterial processes in water, cattle and fracking. In testing methane sources at three national sites, University of Cincinnati geologists found no evidence fracking affected methane concentrations in groundwater in Ohio. At sites in Colorado and Texas, methane sources were founded to be mixed, divided between fracking, cattle and/or landfills.

Robot's in-hand eye maps surroundings, determines hand's location
Before a robot arm can reach into a tight space or pick up a delicate object, the robot needs to know precisely where its hand is. Researchers at Carnegie Mellon University's Robotics Institute have shown that a camera attached to the robot's hand can rapidly create a 3-D model of its environment and also locate the hand within that 3-D world.

Under Pressure: New technique could make large, flexible solar panels more feasible
A new, high-pressure technique may allow the production of huge sheets of thin-film silicon semiconductors at low temperatures in simple reactors at a fraction of the size and cost of current technology. 'By putting the process under high pressure, our new technique could make it less expensive and easier to create the large, flexible semiconductors that are used in flat-panel monitors and solar cells,' said research leader John Badding at Penn State University.

The MoS2 nanocavity can increase the amount of light that ultrathin semiconducting materials absorb. In turn, this could help industry to continue manufacturing more powerful, efficient and flexible electronic devices.
