Glasses strong as steel

15-04-2014

Scientists at Yale University have devised a dramatically faster way of identifying and characterizing complex alloys known as bulk metallic glasses (BMGs), a versatile type of pliable glass that's stronger than steel. Using traditional methods, it usually takes a full day to identify a single ...

Recycling astronaut urine for energy and drinking water

10-04-2014

On the less glamorous side of space exploration, there's the more practical problem of waste — in particular, what to do with astronaut pee. But rather than ejecting it into space, scientists are developing a new technique that can turn this waste burden into a boon by converting it into fuel and ...

Is the power grid too big?

Right-sizing the grid could reduce blackout risk, according to new analysis in the journal 'Chaos'

10-04-2014

Some 90 years ago, British polymath J.B.S. Haldane proposed that for every animal there is an optimal size -- one which allows it to make best use of its environment and the physical laws that govern its activities, whether hiding, hunting, hoofing or hibernating. Today, three researchers are ...

Trees go high-tech

Process turns cellulose into energy storage devices

09-04-2014

Based on a fundamental chemical discovery by scientists at Oregon State University, it appears that trees may soon play a major role in making high-tech energy storage devices. OSU chemists have found that cellulose – the most abundant organic polymer on Earth and a key component of trees – can ...
