Gold may be flashier, but now chemists are giving silver a chance to shine. They've figured out how to make silver nanoparticles that are even more stable than gold nanoparticles. Durable and easy to handle, gold nanoparticles are used for drug delivery, cell imaging and many other applications. Because silver is cheaper and more abundant than gold, it may seem like a more convenient nanomaterial. But unlike gold, silver degrades easily, which makes building stable silver nanoparticles extremely difficult.

LONDON -- Jennie Reed got her silver medal in the women's team pursuit Saturday. What she did not get was a chance to stand on the podium. Each team in this particular cycling event has four members, but uses only three at a time. Because the U.S. women were underdogs to the likes of Great Britain, Australia and Canada, they needed to keep fresh legs on the track. So after Reed teamed with Sarah Hammer and Dotsie Bausch to edge Australia in the first round, coaches replaced her with another American -- Lauren Tamayo -- for the gold-medal race.
