Researchers have demonstrated a prototype device that can rid hands, feet, or even underarms of bacteria, including the hospital superbug MRSA.
The device works by creating something called a plasma, which produces a cocktail of chemicals in air that kill bacteria but are harmless to skin.

Magnetic heat shield test could use Russian launcher
As a capsule re-enters the atmosphere the air heats up around it due to friction and usually a high-temperature-resistant material is needed to absorb that. A magnetic field is able to deflect the hot atmospheric air away from the vehicle's surface, reducing or eliminating the need for a heat-absorbing material.
Jamming Skin Enabled Locomotion
During military operations it can be important to gain covert access to denied or hostile space. Unmanned platforms such as mechanical robots are of limited effectiveness if the only available points of entry are small openings. Under the Chemical Robots (ChemBots) Program, DARPA is creating a new class of soft, flexible, mesoscale mobile objects that can identify and maneuver through openings smaller than their dimensions and perform various tasks.

International Space Station Under Threat of Space Junk Collision
At issue is an old rocket that could force the five astronauts on the orbiting station to change their orbit to avoid getting whacked by the debris. It's a Delta 2 rocket that launched a comet-sampling probe called Stardust from the Kennedy Space Center back on Feb. 7, 1999. The rocket is still up there, and ten years later, it has come back to haunt the International Space Station.

The brain simulation is a feat for neuroscience and computer processing—but it's still one-eighty-third the speed of a human brain and is only as large as a cat's.
How to Stop a Hurricane With Cold Water
Intellectual Ventures, a private company funded in part by Bill Gates, is in the business of chasing wild scientific ideas and, through research, finding out how feasible they are. Their latest project: How to stop hurricanes with cold water.
Warm surface water fuels big storms, so Intellectual Ventures proposes to suppress them by dumping cool water from massive floating bowls of unspecified size, deployed by airplane in front of a storm’s path.
New Reactor Uses Sunlight to Turn Water and Carbon Dioxide Into Fuel
Scientists at Sandia National Labs, seeking a means to create cheap and abundant hydrogen to power a hydrogen economy, realized they could use the same technology to "reverse-combust" CO2 back into fuel. Researchers still have to improve the efficiency of the system, but they recently demonstrated a working prototype of their "Sunshine to Petrol" machine that converts waste CO2 to carbon monoxide, and then syngas, consuming nothing but solar energy.

Building a more versatile laser
One of the drawbacks associated with using semiconductor lasers is that many of them can only produce a beam of a single wavelength, and can only send that beam in one direction at a time. There have been efforts to tune lasers so that different wavelengths can be achieved, but these lasers still emit light only in one direction, and one wavelength at a given time. All that could change, though. Harvard University scientists Federico Capasso and Nanfang Yu , in Cambridge, Massachusetts, have been working with an international team to develop a laser that offers multibeam emission.
Birds 'See' Earth's Magnetic Field

Liquid Cooling Bags For Data Centers Could Trim Cost and Carbon By 90 Percent
Server farms are undeniably awesome in that they store huge pools of data, enable such modern phenomena as cloud computing and Web-hosted email, and most importantly, make the Internet as it stands today possible. The downside: data centers get very, very hot. Cooling huge banks of servers doesn't just cost a lot, it eats up a lot of energy, and that generally means fossil fuels. UK-based Iceotope hopes to cut those costs by about 93 percent by wrapping servers in liquid coolant.
