NASA's Swift sizes up comet ISON Posted: 29 Mar 2013 09:51 AM PDT Astronomers have used NASA's Swift satellite to check out comet C/2012 S1 (ISON), which may become one of the most dazzling in decades when it rounds the sun later this year.

Light may recast copper as chemical industry 'holy grail' Posted: 28 Mar 2013 11:23 AM PDT Wouldn't it be convenient if you could reverse the rusting of your car by shining a bright light on it? It turns out that this concept works for undoing oxidation on copper nanoparticles, and it could lead to an environmentally friendly production process for an important industrial chemical, engineers have discovered.

Discovery opens door to efficiently storing and reusing renewable energy Posted: 28 Mar 2013 11:23 AM PDT Researchers have developed a ground-breaking way to make new affordable and efficient catalysts for converting electricity into chemical energy. Their technology opens the door to homeowners and energy companies being able to easily store and reuse solar and wind power. Such energy is clean and renewable, but it's available only when the sun is shining or the wind is blowing.

Clays can expand under pressure Posted: 27 Mar 2013 06:25 AM PDT It was always believed that water is "squeezed" out of the clay structure under pressure but physicists in Sweden together with German colleagues show that this appear to be not always true if excess of liquid water is available around.
