Scientists Solved the Mystery of Why Rechargeable Batteries Go Bad

Every time you recharge your lithium-ion batteries, their storage capacity decreases just a little bit. That is why your mobile gadgets won't stay on nearly as long as they did even a year ago. But thanks to research by the US Department of Energy, we finally know why exactly that occurs and, more importantly, how to… » 5/29/14 1:40pm 5/29/14 1:40pm

Princeton Nuke Detector Could Spot World-Ending Warheads

The US and USSR had more than 60,000 nuclear warheads pointed at each other at the height of the Cold War. While the Non-Proliferation Treaty of 1970 and START in 1994 have shrunk that figure to around 26,000, nobody is really sure how many still exist—because nobody’s ever actually verified the number of warheads,… » 4/30/13 11:30am 4/30/13 11:30am

This Natural Gas Plant Is Turbo-Charged by the Sun

With the decreasing popularity of coal and increasing volatility of petroleum prices, natural gas is emerging as a major energy resource in the the United States. And while we have plenty of reserves, an estimated 318 Trillion cubic feet (Tcf), it's still a non-renewable resource that must be used sparingly whenever… » 4/15/13 11:50am 4/15/13 11:50am

Add the Department of Energy to the List of Agencies Nailed by Hackers

The hack was revealed in a letter obtained by Reuters, which was sent to employees on Friday. The DOE claims no confidential information was lost in the attack. » 2/04/13 5:57pm 2/04/13 5:57pm

The Sludge-Busting MARS Arm Blasts Through Radioactive Waste

In 1943, the US government needed a reliable center for processing the Manhattan Project's nuclear material. Officials chose the 568-acre Hanford site in the deserts of Washington State to house nine nuclear reactors and 143 single-walled, underground waste tanks. Fast-forward 68 years and the US government is still… » 11/08/11 11:30am 11/08/11 11:30am

Cray XT Jaguar: The New World's Fastest Supercomputer

Pumping out a sustained 1.64 quadrillion mathematical calculations per second (1.64 petaflops) after a recent technological overhaul, the Cray XT Jaguar is now the world's latest fastest supercomputer (huge disclaimer coming) for non-classified research. And once you see what's under the hood, you'll know why.The… » 11/12/08 10:20am 11/12/08 10:20am

Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity…

The latest edition of Nature magazine details a new method scientists have derived for converting heat energy into electricity, using silicon to instigate the conversion. Researchers have more investigations to carry out, but if preliminary findings are indicative of what is to come, appliances that charge using your… » 1/13/08 7:25pm 1/13/08 7:25pm
