NASA Interested in Nuclear-Powered Bacteria

2.8 kilometers (1,7 miles) of rock separate Candidatus Desulforudis Audaxviator (CDA) from the outside world, depriving it of light and oxygen to feed on. But the bacterium adapted to its environment and started using the radioactive decay of the uranium around it as a primary source of energy. It also developed genes to help it synthesize carbon and nitrogen from rocks. Researchers say the cell is able to extract everything it needs from its environment, as the two chemicals are the building blocks of life as we know it.

A concept of a nuclear reactor buried below the lunar surface to make use of lunar soil as additional radiation shielding. The engines that convert heat energy to electricity are in the tower above the reactor, and radiators extend out from the tower to radiate into space any leftover heat energy. The power system would transmit 40 kilowatts of electric power, enough for about eight houses on Earth, to the lunar outpost. Credit: NASA

Bacteria Found in Compost Could Be a Boost for Ethanol Production

At the Society for General Microbiology's Autumn meeting in early September, held at Trinity College in Dublin, Ireland, researchers from Guildford, United Kingdom (UK) announced successful development of a bacteria strain that can break down organic wastes into ethanol. Unlike traditional yeastbased fermentation for ethanol, which is energy intensive and expensive, the bacteria is expected to create ethanol more efficiently and cheaply. TMO Renewables, based in Guildford, screened thousands of bacteria before finding one that could both survive high temperatures and thrive on a wide variety of plant materials. "We found some heat-loving bacteria in a compost heap, from the Geobacillus family, which in their wild form produce lactic acid as a by-product of sugar synthesis when they break down biomass," says Paul Milner, TMO's Fermentation

50 Consumer Technologies Developed by NASA in the Last 50 Years

Every year NASA publishes a new edition of their Spinoff magazine, a periodical that outlines NASA-based technologies that have disseminated into everyday devices, improving our lives beyond giving us some nifty new desktop wallpapers. This year marks the 50th anniversary of Spinoff, and to celebrate, NASA has created a "best of" list (that we pasted after the jump). From the aerodynamic principles applied to tractor trailers to advanced imaging techniques that allow 360-degree Real Estate photo tours, NASA demonstrates that their technological breakthroughs are about more than just sticking an American flag on the moon.

International Cooperation Needed To Lower Proliferation Risks As Nuclear Energy Grows

As more nations pursue nuclear power, the United States and Russia, along with other countries and the International Atomic Energy Agency (IAEA), should redouble efforts to ensure a reliable supply of nuclear fuel so that countries seeking nuclear energy have less incentive to build their own facilities to enrich uranium and reprocess spent nuclear fuel, says a new report by the U.S. National Academy of Sciences and Russian Academy of Sciences.

Soaring, Cryptography, and Nuclear Weapons

Martin Hellman sends in a pointer to his essay that uses analogies from cryptography and the sport of soaring in an attempt to draw people in to thinking about the risks of nuclear weapons. Quoting: "... I did a preliminary risk analysis which indicates that relying on nuclear weapons for our security is thousands of times more dangerous than having a nuclear power plant built next to your home." Hellman is best known as co-inventor (with Diffie and Merkle) of public key cryptography, and has worked for over twenty-five years to reduce the threat posed by nuclear weapons. He is also a glider pilot with over 2,600 logged hours. Hellman adds, "Readers needing a break can go to some photos of the Sierra Nevada mountains taken from my glider."

40 Years Ago, the US Lost a Nuclear Bomb

Hugh Pickens writes "A BBC investigation has found that in 1968 the US abandoned a nuclear weapon beneath the ice in northern Greenland after a nuclear-armed B52 crashed on the ice a few miles from Thule Air Base. The Stratofortress disintegrated on impact with the sea ice and parts of it began to melt through to the fjord below. The high explosives surrounding the four nuclear weapons on board detonated without setting off the nuclear devices, which had not been armed by the crew. The Pentagon maintained that all four weapons had been 'destroyed' and while technically true, investigators piecing together fragments from the crash could only account for three of the weapons. Investigators found that 'something melted through ice such as burning primary or secondary.

NASA's Moon Rocket Ares I May Not Fly

NASA's latest version of moon craft, the very one who put its original designer, Michael Griffin, in the position of NASA administrator 3 years ago, has encountered new glitches. This would mean millions of dollars over the budget and a considerable lag in terms of deadline, but NASA is prepared to do anything to see the rocket lift off. The Ares I issues and the management approach of the agency have angered much of the personnel. Most of them would rather see the rocket not leaving the ground than give in to the compromises that would possibly help the craft reach the Moon.
