Recalculating the distance to interstellar space

Posted: 15 Jun 2011 11:11 AM PDT

Scientists analyzing recent data from NASA's Voyager and Cassini spacecraft have calculated that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously thought.

NASA's Chandra finds massive black holes common in early universe

Posted: 15 Jun 2011 10:53 AM PDT

Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. This discovery from NASA's Chandra X-ray Observatory shows that very young black holes grew more aggressively than previously thought, in tandem with the growth of their host galaxies.

Researchers break light-matter coupling strength limit in nanoscale semiconductors

Posted: 15 Jun 2011 10:20 AM PDT

New engineering research demonstrates that polaritons have increased coupling strength when confined to nanoscale semiconductors. This represents a promising advance in the field of photonics: smaller and faster circuits that use light rather than electricity.

Neutrinos change flavors while crossing Japan: Findings shed light on why universe is made of matter instead of anti-matter

Posted: 15 Jun 2011 07:32 AM PDT

By shooting a beam of neutrinos through a small slice of the Earth under Japan, physicists say they've caught the particles changing their stripes in new ways. These observations may one day help explain why the universe is made of matter rather than anti-matter.

Scientists prove existence of 'magnetic ropes' that cause solar storms

Posted: 15 Jun 2011 07:32 AM PDT

Scientists discovered recently that a phenomenon called a giant magnetic rope is the cause of solar storms. Confirming the existence of this formation is a key first step in helping to mitigate the adverse effects that solar storm eruptions can have on satellite communications on Earth.

First self-powered device with wireless data transmission

Posted: 15 Jun 2011 07:30 AM PDT

Scientists are reporting development of the first self-powered nano-device that can transmit data wirelessly over long distances. Researchers say it proves the feasibility of a futuristic genre of tiny implantable medical sensors, airborne and stationary surveillance cameras and sensors, wearable personal electronics, and other devices that operate independently without batteries on energy collected from the environment.

New sensor to measure structural stresses can heal itself when broken

Posted: 15 Jun 2011 07:30 AM PDT

Researchers have designed a sensor that can measure strain in structural materials and is capable of healing itself -- an important advance for collecting data to help us make informed decisions about structural safety in the wake of earthquakes, explosions or other unexpected events.

Coming to TV screens of the future: A sense of smell

Posted: 15 Jun 2011 06:45 AM PDT

In a new paper, engineers demonstrate that it is possible to generate odor, at will, in a compact device small enough to fit on the back of your TV with potentially thousands of odors.

New catalyst will allow commercialization of revolutionary fuel cells

Posted: 15 Jun 2011 03:22 AM PDT

Cheap, much lighter than before and allowing for continuous operation – what traditional batteries can not offer – direct formic acid fuel cells can revolutionize the portable electronics market. A new catalyst will enable a widespread use of fuel cells, researchers say.
