Technique turns computer chip defects into an advantage (January 1, 2011) -- Physicists have discovered that tiny defects inside a computer chip can be used to tune the properties of key atoms in the chip. The technique involves rearranging the holes left by missing atoms to tune the properties of dopants -- the chemical impurities that give the semiconductors in computer chips their special properties. ... > full story
New cognitive robotics lab tests theories of human thought (December 31, 2010) -- Researchers are exploring how human thought outwits brute force computing in the real world. Twenty programmable robots allow students to test the real-world performance of computer models that mimic human thought. ... > full story
Demise of large satellite may have led to the formation of Saturn’s rings and inner moons (December 31, 2010) -- Simulations may explain how Saturn's majestic rings and icy inner moons formed following the collision of a Titan-sized satellite with the planet, according to a new article. ... > full story
New technology to speed cleanup of nuclear contaminated sites (December 31, 2010) -- Engineers have invented a new type of radiation detection and measurement device that will be particularly useful for cleanup of sites with radioactive contamination, making the process faster, more accurate and less expensive. ... > full story
System for detecting noise pollution in the sea and its impact on cetaceans (December 31, 2010) -- Researchers have developed the first system equipped with hydrophones able to record sounds on the seafloor in real time over the Internet. The system detects the presence of cetaceans and makes it possible to analyze how noise caused by human activity can affect the natural habitat of these animals and the natural balance of oceans. A new EU directive on the sea has ruled that all member states must comply with a set of indicators for measuring marine noise pollution before 2012. ... > full story
Study classifies and uses artificial proteins to analyze protein-protein interfaces (December 31, 2010) -- A new study suggests that there may be roughly a thousand structurally distinct protein-protein interfaces -- and that their structures depend largely on the simple physics of the proteins. ... > full story
Your genome in minutes: New technology could slash sequencing time (December 31, 2010) -- Scientists are developing technology that could ultimately sequence a person's genome in mere minutes, at a fraction of the cost of current commercial techniques. ... > full story
Light dawns on dark gamma-ray bursts (December 30, 2010) -- Gamma-ray bursts are among the most energetic events in the Universe, but some appear curiously faint in visible light. The biggest study to date of these so-called dark gamma-ray bursts, using the 2.2-meter MPG/ESO telescope at La Silla in Chile, has found that these explosions don't require exotic explanations. Their faintness is now explained by a combination of causes, the most important of which is the presence of dust between the Earth and the explosion. ... > full story
Catching video pirates: Invisible DNA-like fingerprint on video assist law enforcement (December 30, 2010) -- Scientists are applying an invisible DNA-like fingerprint to film, turning the footage into a series of numbers. When the film is then bootlegged onto the Internet, the invisible fingerprint goes with it, so that it can be traced over the Web -- back to the original video pirate, who can then be tracked and arrested. ... > full story
Vertical search across the educational horizon: New search tools could facilitate access to online educational resources (December 30, 2010) -- General search engines, while very effective at tracking down information, are nevertheless unstructured, which limits the user's ability to further automate the processing of the search results, researchers point out in a new article. ... > full story
GOES satellites watch 2011 approach, look back at 2010 (December 30, 2010) -- The GOES series of satellites keep an eye on the weather happening over the continental US and eastern Pacific and Atlantic oceans and had a busy time with wild weather in 2010. GOES-13 just captured one of the last images of North and South America in 2010 as the world continues to turn toward 2011. ... > full story
'Breathalyzers' may be useful for medical diagnostics (December 29, 2010) -- Researchers have overcome a fundamental obstacle in developing breath-analysis technology to rapidly diagnose patients by detecting chemical compounds called "biomarkers" in a person's respiration in real time. ... > full story
