| Posted: 06 Jan 2013 11:57 AM PST A new photodetector can cleanly discriminate among four states, not just the standard two states of binary logic.  |
| Wide binary stars wreak havoc in planetary systems, astrophysicists find Posted: 06 Jan 2013 11:57 AM PST Astrophysicists have shown that planetary systems with very distant binary stars are particularly susceptible to violent disruptions, more so than if they had stellar companions with tighter orbits around them. Unlike the sun, many stars are members of binary star systems -- where two stars orbit one another -- and these stars' planetary systems can be altered by the gravity of their companion stars.  |
| From the Amazon rainforest to human body cells: Quantifying stability Posted: 06 Jan 2013 11:57 AM PST The Amazon rainforest, energy grids, and cells in the human body share a troublesome property: They possess multiple stable states. When the world's largest tropical forest suddenly starts retreating in a warming climate, energy supply blacks out, or cells turn carcinogenic, complex-systems science understands this as a transition between two such states. These transitions are obviously unwanted.  |
| Ordinary glass's extraordinary properties revealed Posted: 06 Jan 2013 11:56 AM PST Researchers raise the possibility of designing ultrastable glasses at the molecular level via a vapor-deposition process. Such glasses could find potential applications in the production of stronger metals and in faster-acting pharmaceuticals.  |
