New look at multitalented protein sheds light on mysteries of HIV (October 15, 2010) -- New insights into the human immunodeficiency virus (HIV) infection process, which leads to acquired immunodeficiency syndrome (AIDS), may now be possible through a research method that allows scientists to glimpse an important protein molecule's behavior with unprecedented clarity. ... > full story
Cancer screening made simple, thanks to micro-fluidic technology (October 15, 2010) -- Current cervical cancer screening is time consuming and expensive, but now new breakthrough technology developed by European researchers should allow large-range screening by non-medical personnel with almost immediate results and at a much lower cost. ... > full story
Eat safer: Novel approach detects unknown food pathogens (October 15, 2010) -- Researchers have developed a novel approach to automated detection and classification of harmful bacteria in food. The investigators have designed and implemented a sophisticated statistical approach that allows computers to improve their ability to detect the presence of bacterial contamination in tested samples. ... > full story
Changing the color of single photons emitted by quantum dots (October 15, 2010) -- Researchers have demonstrated for the first time the conversion of single photons produced by a true quantum source to a near-visible wavelength. The ability to change the color of single photons may aid in the development of hybrid quantum systems for applications in quantum communication, computation and metrology. ... > full story
Computers to read your body language? (October 15, 2010) -- Can a computer read your body language? A consortium of European researchers thinks so, and has developed a range of innovative solutions from escalator safety to online marketing. ... > full story
Mysterious pulsar with hidden powers discovered (October 15, 2010) -- Dramatic flares and bursts of energy -- activity previously thought reserved for only the strongest magnetized pulsars -- has been observed emanating from a weakly magnetized, slowly rotating pulsar. Astrophysicists who made the discovery believe that the source of the pulsar's power may be hidden deep within its surface. ... > full story
Improved 'molecular fingerprinting' for trace gas detection unveiled (October 15, 2010) -- Scientists have demonstrated an improved laser-based "molecular fingerprinting" technique that picks out traces of key molecules from a billion other particles in a gas in just 30 seconds or less. ... > full story
New materials could replace costly gold in electrical applications (October 15, 2010) -- Researchers have modeled and developed new classes of materials with contact properties near those of pure gold. With the price of gold currently hovering around ,340 per ounce, manufacturers across the globe are scrambling for alternatives to the costly noble metals that are widely used in electronic applications, including gold, platinum, rhodium, palladium and silver. ... > full story
Safeguarding data in future quantum computing: Physicists detect and control quantum states in diamond with light (October 15, 2010) -- Physicists have succeeded in combining laser light with trapped electrons to detect and control the electrons' fragile quantum state without erasing it. This is an important step toward using quantum physics to expand computing power and to communicate over long distances without the possibility of eavesdropping. ... > full story
New system for locating and capturing satellites in space (October 15, 2010) -- Scientists in Spain have developed a new system for docking and capturing space satellites based on robotics and computer vision technology to autonomously guide a space vehicle to dock and capture the satellites. ... > full story
'Incoherent excitations' govern key phase of superconductor behavior (October 15, 2010) -- Physicists have found that high-temperature superconductivity in copper oxides is linked to what they term "incoherent excitations" -- a discovery that sheds light on the electronic response of these materials before they become superconducting. ... > full story
Charcoal biofilter cleans up fertilizer waste gases (October 15, 2010) -- Removing the toxic and odorous emissions of ammonia from the industrial production of fertilizer is a costly and energy-intensive process. Now, researchers in Bangladesh have turned to microbes and inexpensive wood charcoal to create a biofilter that can extract the noxious gas from vented gases and so reduce pollution levels from factories in the developing world. ... > full story
