IceCube experiment finds Earth can block high-energy particles from nuclear reactions

24-Nov-2017

For the first time, a science experiment has measured Earth's ability to absorb neutrinos -- the smaller-than-an-atom particles that zoom throughout space and through us by the trillions every second at nearly the speed of light. The experiment was achieved with the IceCube detector, an array of ...

Organic/inorganic sulfur may be key for safe rechargeable lithium batteries

16-Oct-2017

We have come a long way from leaky sulfur-acid automobile batteries, but modern lithium batteries still have some down sides. Now a team of Penn State engineers have a different type of lithium sulfur battery that could be more efficient, less expensive and safer. "We demonstrated this method in ...
