Escaping gravity's clutches: Information could escape from black holes after all, study suggests

Posted: 10 Aug 2011 06:53 PM PDT

New research gives a fresh perspective on the physics of black holes. Conventional thinking asserts that black holes swallow everything that gets too close and that nothing can escape, but a new study suggests that information could escape from black holes after all.

Revolutionary material dramatically increases explosive force of weapons

A revolutionary material that will replace steel in warhead casings will bring added lethality and increase the likelihood of a hit on an enemy target, Navy researchers say.

Working towards replacing platinum in fuel cells: Performance of iron-based catalysts improved

Posted: 10 Aug 2011 10:31 AM PDT

Researchers have developed a new and improved iron-based catalyst capable of generating even more electric power in fuel cells for transportation applications. Previously, only platinum-based catalysts could produce similar performance.

New anti-censorship scheme could make it impossible to block individual Web sites

Posted: 10 Aug 2011 10:30 AM PDT

A radical new approach to thwarting Internet censorship would essentially turn the whole Web into a proxy server, making it virtually impossible for a censoring government to block individual Web sites.

Quantum computers? Physicists 'entangle' two atoms using microwaves for the first time

Posted: 10 Aug 2011 10:28 AM PDT

Physicists have for the first time linked the quantum properties of two separated ions (electrically charged atoms) by manipulating them with microwaves instead of the usual laser beams.

Phone losing charge? With photovoltaic polarizers, devices could be powered by sunlight, own backlight

Posted: 10 Aug 2011 06:38 AM PDT

Researchers have developed a novel energy harvesting and recycling concept for electronic devices -- incorporating their LCD screens with built-in photovoltaic polarizers -- so they could convert ambient light, sunlight, and the device's own backlight into electricity. Called polarizing organic photovoltaics (or ZOPVs), these can potentially boost the function of a LCD, Light Crystal Displays, by working simultaneously as a polarizer, as a photovoltaic device and as an ambient light or sunlight photovoltaic panel.

Astronomy: A spectacular spiral in Leo

Posted: 10 Aug 2011 05:55 AM PDT

A new picture shows NGC 3521, a spiral galaxy located about 35 million light years away in the constellation of Leo (The Lion). Spanning about 50 000 light-years, this spectacular object has a bright and compact nucleus, surrounded by richly detailed spiral structure.

Exotic quantum crystal discovered: Researchers discover novel state of crystal matter

Posted: 10 Aug 2011 05:55 AM PDT

Nature knows two opposite types of solids: One that emerges upon compression from a liquid and a second that appears if the pressure on a liquid is reduced. While the former is typical for substances in our everyday life the latter occurs for example in a dense quantum liquid of electrons (such as in metals) or ions (in exotic white dwarf or neutron stars). Now it has been shown that there exists yet a third form of matter that inherits both of these properties.

Diamond’s quantum memory

Posted: 10 Aug 2011 05:54 AM PDT

Two completely different quantum systems have been successfully joined. This should pave the way to feasible quantum-computer microchips.
