TOKYO, Mar. 18, 2011 (Reuters) Japanese engineers conceded on Friday that burying a crippled nuclear plant in sand and concrete may be the only way to prevent a catastrophic radiation release, the method used to seal huge leakages from Chernobyl in 1986.

Officials said they still hoped to fix a power cable to at least two reactors to restart water pumps needed to cool overheating nuclear fuel rods. Workers also sprayed water on the No.3 reactor, one of the most critical of the plant's six.

ScienceDaily (May 25, 2010) Researchers at the University of Leeds have uncovered new clues to the origins of life on Earth.

The team found that a compound known as pyrophosphite may have been an important energy source for primitive lifeforms.

There are several conflicting theories of how life on Earth emerged from inanimate matter billions of years ago -- a process known as abiogenesis.

A tiny radio chip implanted in a moth harvests power and senses neural activity.

Thanks to the shrinking size of electronics, researchers have been exploring increasingly sophisticated implantable devices, paving the way for new prosthetics and brain-machine interfaces. But a big challenge has been how to deliver power to electronic components embedded within the body.

A continuously variable transmission could lead to cheaper wind power--if it is rugged enough.

Federal stimulus funds awarded to a wind-energy research consortium led by Illinois Institute of Technology will accelerate testing of small wind turbines that could point the way towards more efficient utility-scale machines. more...

Erma Bombeck once wrote, "When you look like your passport photo, it's time to go home." Of course, if you have the right equipment with you, such as travel hairdryers and curling irons, you can hold that passport look at bay just a little bit longer. Plus, when you travel you need to bring along all sorts of travel gadgets: a digital camera to document your trip, a laptop to keep in touch with everyone back home and even an MP3 player to tune out your traveling companions.

Batteries­ are pr­actically essential devices but present a whole ho­st of problems. Over time they can have trouble retaining a charge. Some stop working altogether. Others overheat or leak or even explode. They're also rigid and sometimes bulky. Then how about, instead of your standard AA or lithium-ion, a flexible, incredibly thin battery that could be powered by blood or sweat? Seems like an improvement, right?

Unless you're particularly organized and good with those little twist ties, you probably have a few dusty power cord tangles around your home. But wireless power transmission could soon cut the clutter and lead to clean sources of electricity.

Tons of products use transformers. Walk around your home and you probably see them everywhere. In my house, I found them attached to my printer, scanner, speakers, answering machine, cordless phone, electric screwdriver, electric drill, baby monitor, clock radio, camcorder You get the idea. A typical home probably has five to 10 of these little transformers plugged into the wall at any given time.
