Thomas Edison famously said that genius is 1 percent inspiration and 99 percent perspiration — words that could well apply to a new machine promoted by UNICEF that turns human sweat into drinking water.

The Sweat Machine extracts moisture from worn clothes by spinning and heating them, then filters the resulting liquid so that only pure water remains. It was built by Swedish engineer and TV personality Andreas Hammar, and uses a technology developed by Sweden's Royal Institute of Technology and the water purification company HVR.

Volcano 'Screams' Before Eruption

Researchers have discovered the largest virus ever, and they've given it a terrifying name: Pandoravirus.

"This is not going to cause any kind of widespread and acute illness or epidemic or anything," says Eugene Koonin, an evolutionary biologist at the National Institutes of Health who specializes in viruses.
