NASA Warns of Potential "Huge Space Storm" In 2013 464

Posted by kdawson from the after-twenty-twelve-who-cares dept.
Low Ranked Craig writes "Senior space agency scientists believe the Earth will be hit with unprecedented levels of magnetic energy from solar flares after the Sun wakes 'from a deep slumber' sometime around 2013. In a new warning, NASA said the super storm could hit like 'a bolt of lightning' and could cause catastrophic consequences for the world's health, emergency services, and national security — unless precautions are taken. Scientists believe damage could extend to everyday items such as home computers, iPods, and sat navs. 'We know it is coming but we don't know how bad it is going to be,' said Dr. Richard Fisher, the director of NASA's Heliophysics division. 'I believe we're on the threshold of a new era in which space weather can be as influential in our daily lives as ordinary terrestrial weather.' Fisher concludes. 'We take this very seriously indeed.'"

"Spin Battery" Effect Discovered 234

Posted by kdawson from the usual-caveats-apply dept.
An anonymous reader writes "Researchers at the University of Miami and at the Universities of Tokyo and Tohoku, in Japan, have discovered a spin battery effect: the ability to store energy into the magnetic spin of a material and to later extract that energy as electricity, without a chemical reaction. The researchers have built an actual device to demonstrate the effect that has a diameter about that of a human hair. This is a potentially game-changing discovery that could affect battery and other technologies. Quoting: Although the actual device... cannot even light up an LED..., the energy that might be stored in this way could potentially run a car for miles. The possibilities are endless, Barnes said.'"
