| New material possible boon for lithium ion batteries Posted: 08 Sep 2011 11:53 AM PDT Batteries could get a boost from a discovery that increases power, energy density and safety while dramatically reducing charge time.  |
| Posted: 08 Sep 2011 11:51 AM PDT Usually, running five minutes late is a bad thing since you might lose your dinner reservation or miss out on tickets to the latest show. But when a planet runs five minutes late, astronomers get excited because it suggests that another world is nearby. NASA's Kepler spacecraft has spotted a planet that alternately runs late and early in its orbit because a second, "invisible" world is tugging on it.  |
| Neutron scattering confirms DNA is as stretchy as nylon Posted: 08 Sep 2011 06:10 AM PDT Neutron scientists have measured how fast sound travels along DNA to determine its 'stiffness'. These findings help to explain how DNA folds, coils and denatures.  |
| Posted: 07 Sep 2011 10:20 AM PDT Ultra high precision analyses of some of the oldest rock samples on Earth provides clear evidence that the planet's accessible reserves of precious metals are the result of a bombardment of meteorites more than 200 million years after Earth was formed.  |
