| Dwarf galaxies provide new insights on dark matter Posted: 02 Apr 2012 03:53 PM PDT Scientists have looked for signals from dark matter by zeroing in on 10 small, faint galaxies that orbit our own. Although no signals have been detected, a novel analysis technique applied to two years of data from the observatory's Large Area Telescope has essentially eliminated these particle candidates for the first time.  |
| Graphene membranes: First controllable use of scanning tunneling microscopy on freestanding graphene Posted: 02 Apr 2012 03:52 PM PDT Physicists have developed a technique that allows them to control the mechanical property, or strain, on freestanding graphene. By controlling the strain, they also can control other properties of this important material.  |
| Computer scientist leads the way to the next revolution in artificial intelligence Posted: 02 Apr 2012 08:30 AM PDT Scientists have taken Alan Turing's work to its next logical step, translating her 1993 discovery into an adaptable computational system that learns and evolves way much more like our brains do.  |
| Posted: 02 Apr 2012 08:30 AM PDT New algorithms could enable heaps of "smart sand" that can assume any shape, allowing spontaneous formation of new tools or duplication of broken mechanical parts.  |
| Link between violent computer games and aggressiveness questioned Posted: 02 Apr 2012 08:28 AM PDT There is a long-lasting and at times intense debate about the possible link between violent computer games and aggressiveness. Researchers are now questioning the entire basis of the discussion. Researchers now present a new study showing that, more than anything, a good ability to cooperate is a prerequisite for success in the violent gaming environment.  |
| New quantum encryption method foils hackers Posted: 02 Apr 2012 06:43 AM PDT Scientists have found a new quantum encryption method to foil even the most sophisticated hackers. Researchers have come up with a simple solution to the untrusted device problem. Their method is called "Measurement Device Independent QKD." The aim is to detect subtle changes that occur when quantum data is manipulated by a third party.  |
| Growing up supermassive: A black hole's diet of stars Posted: 02 Apr 2012 06:43 AM PDT Astrophysicists have found a new explanation for the growth of supermassive black holes in the center of most galaxies: They repeatedly capture and swallow single stars from pairs of stars that wander too close.  |
| South Pole telescope homes in on dark energy, neutrinos Posted: 02 Apr 2012 06:31 AM PDT Analysis of data from the 10-meter South Pole Telescope is providing new support for the most widely accepted explanation of dark energy -- the source of the mysterious force that is responsible for the accelerating expansion of the universe.  |
