Scientists Create Bacteria that Glows to Reveal Land Mines

According to Edinburgh University scientists, the new strain of bacteria can be sprayed onto local affected areas or air dropped over entire fields of mines. Within a few hours the bacteria strain begins to glow green wherever traces of explosive chemicals are present.

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

When birds migrate over long distances -- sometimes thousands of miles -- they usually end up in exactly the same place year after year. Such accurate feats of navigation, accomplished by millions of birds every year, have long made scientists wonder how they do it. Now a group of scientists in Germany has experimental evidence that reveals an important part of the secret of birds' navigational success.

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.

DARPA Wants Cryogenic Technology on the Battlefield to Freeze Traumatic Brain Injury in its Tracks

Blasts from improvised explosives and RPGs can cause traumatic brain injuries among soldiers, which can leave permanent damage. Sounds like a challenge for the Pentagon's mad science lab DARPA, which has issued a call for a brain freeze device that could stop the after-effects of brain trauma in its tracks.

University of Adelaide researchers put the squeeze on light using nanoscale optical fibers

Scientists at the University of Adelaide in Australia have made a breakthrough that could change the world's thinking on what light is capable of. The researchers in the University's new Institute for Photonics & Advanced Sensing (IPAS) have discovered that light within optical fibers can be squeezed into much tighter spaces than was previously believed possible.

Widetronix goes nuclear to build a 25-year battery

A company called Widetronix has developed a 25-year battery. Reminiscent of Heinlein’s micro-fission reactors that could be worn on a belt, beta voltaic battery cells last 25 years or more, using semiconductors to turn high energy electrons known as beta particles thrown off by radioactive decay into a usable current.

AMD, Asian packager license Irish micro-cooler

Researchers at the Stokes Institute in the University of Limerick have announced two licensing agreements that could see 'micro-cooler' technology used in computers.

Stokes Institute has specialized in thermal management, including microfluidics, and the technology has evolved over five years. Researchers there identified a series of previously unreported cooling interactions that can take place within and at material interfaces and that could be manipulated to create more efficient thermal management of electronic devices.

Darpa’s ‘Liquid Laser’ Gunship Program Pushes Ahead

The Pentagon’s mad science arm is moving ahead with a project to build a laser weapon “compact enough to be carried on board a tactical aircraft - say a B-1B bomber or an AC-130 gunship,” Aviation Week reports.

Darpa is getting ready to hand out 24-month research contracts to defense contractors Textron or General Atomics for the next phase of its High Energy Liquid Laser Area Defense System (HELLADS) program.
