ScienceNow: Although improvements in laptop computers and other electronics continue at a torrid pace, the batteries that power them have made only modest strides in recent years. A new advance in nanotechnology could change all that. Lithium ion batteries made with tiny whiskers of silicon can store as much as 10 times the charge of conventional rechargeables, researchers report. In principle, the new technology could result in laptop batteries that run for days and electric cars that cruise for hundreds of kilometers on a single charge--but it must still clear some key hurdles to make it to market.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
