Researchers pinpoint the cause of MRI vertigo: Machine's magnetic field pushes fluid in the inner ear's balance organ (September 23, 2011) -- A team of researchers says it has discovered why so many people undergoing magnetic resonance imaging (MRI), especially in newer high-strength machines, get vertigo, or the dizzy sensation of free-falling, while inside or when coming out of the tunnel-like machine. ... > full story
New source of super-chilled neutrons provides tools for understanding fundamental physics concepts (September 23, 2011) -- Research into fundamental constants of nature and the search for new particles will benefit from new production method for ultra-cold neutrons. ... > full story
Cloaking magnetic fields: First antimagnet developed (September 23, 2011) -- Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, making the cloak undetectable. ... > full story
Producing flexible CIGS solar cells with record efficiency (September 23, 2011) -- New technology has yielded flexible solar cells with an 18.7% record efficiency. Key to the breakthrough is the control of the energy band gap grading in the copper indium gallium (di)selenide semiconductor, also known as CIGS, the layer that absorbs light and converts it into electricity. Scientists achieved this by controlling the vapor flux of elements during different stages of the evaporation process for growing the CIGS layer. ... > full story
Solar activity can affect re-entry of UARS satellite (September 23, 2011) -- The Upper Atmosphere Research Satellite (UARS) is headed toward Earth, but it hasn't been easy to precisely determine the path and pace of UARS because space itself changes over time -- in response to incoming energy and particles from the sun. ... > full story
Particles appear to travel faster than light: OPERA experiment reports anomaly in flight time of neutrinos (September 23, 2011) -- Scientists with the OPERA experiment, which observes a neutrino beam from CERN 730 km away at Italy's INFN Gran Sasso Laboratory, are presenting surprising new results that show neutrinos traveling faster than light. The OPERA result is based on the observation of over 15,000 neutrino events measured at Gran Sasso, and appears to indicate that the neutrinos travel at a velocity 20 parts per million above the speed of light, nature's cosmic speed limit. Given the potential far-reaching consequences of such a result, independent measurements are needed before the effect can either be refuted or firmly established. ... > full story
New targets for the control of HIV predicted using a novel computational analysis (September 23, 2011) -- Over 25 years of intensive research have failed to create a vaccine for preventing HIV. A new computational approach has predicted numerous human proteins that the human immunodeficiency virus requires to replicate itself -- "a powerful resource for experimentalists who desire to discover new targets." ... > full story
New metal hydride clusters provide insights into hydrogen storage (September 23, 2011) -- A new study has shed light on a class of heterometallic molecular structures whose unique features point the way to breakthroughs in the development of lightweight fuel cell technology. The structures contain a previously-unexplored combination of rare-earth and d-transition metals ideally suited to the compact storage of hydrogen. ... > full story
Spiral constriction: How dynamin mediates cellular nutrient uptake (September 23, 2011) -- Researchers have determined the molecular structure of dynamin -- a "wire-puller" that mediates nutrient uptake into the cell. Since pathogens such as HIV can also enter the body's cells in this way, understanding the underlying molecular mechanisms can potentially open up new approaches for medical applications. ... > full story
Lessons to be learned from nature in photosynthesis (September 23, 2011) -- Lessons to be learned from nature could lead to the development of an artificial version of photosynthesis that would provide us with an absolutely clean and virtually inexhaustible energy source, say researchers. ... > full story
Scientists lay out plans for efficient harvesting of solar energy (September 23, 2011) -- Solar power could be harvested more efficiently and transported over long distances using tiny molecular circuits, according to research inspired by new insights into natural photosynthesis. ... > full story
Faster than light? Neutrino finding puzzles scientists (September 23, 2011) -- Neutrinos that travel faster than light? This seems to be the conclusion of the measurements performed by a team of researchers with the OPERA international experiment. ... > full story
