Synthetic biomaterials mimic cellular membranes: Use in nanomedicine, drug delivery (May 23, 2010) -- An international collaboration led by chemists and engineers has prepared a library of synthetic biomaterials that mimic cellular membranes and that show promise in targeted delivery of cancer drugs, gene therapy, proteins, imaging and diagnostic agents and cosmetics safely to the body in the emerging field called nanomedicine. ... > full story
Schooling fish offer new ideas for wind farming (May 23, 2010) -- The quest to derive energy from wind may soon be getting some help from a fluid-dynamics expert -- and a school of fish. ... > full story
Enabling video systems to react intelligently to content (May 23, 2010) -- Highly sophisticated video-content analysis now makes possible fast and reliable diagnosis of pulmonary embolisms, automatically detects threatening situations in surveillance scenarios and can provide more enjoyable and customized home entertainment. The systems achieve this by reacting not only to the contents of the data but also to the context. Commercial applications are already developing across Europe. ... > full story
Invention regulates nerve cells electronically (May 22, 2010) -- A major step toward being able to regulate nerve cells externally with the help of electronics has been taken by researchers in Sweden. The breakthrough is based on an ion transistor of plastic that can transport ions and charged biomolecules and thereby address and regulate cells. ... > full story
Gesture-based computing on the cheap: Multicolored gloves making Minority Report-style interfaces more accessible (May 22, 2010) -- Ever since Steven Spielberg's 2002 sci-fi movie Minority Report, in which a black-clad Tom Cruise stands in front of a transparent screen manipulating a host of video images simply by waving his hands, the idea of gesture-based computer interfaces has captured the imagination of technophiles. Researchers have now developed a system that could make gestural interfaces much more practical. Aside from a standard webcam, like those found in many new computers, the system uses only a single piece of hardware: a multicolored Lycra glove that could be manufactured for about a dollar. ... > full story
Breaking the logjam: Improving data download from outer space (May 22, 2010) -- Space satellites that detect nuclear events and environmental gasses face a data logjam because their increasingly powerful sensors produce more information than their bandwidth can easily transmit. Experiments at the International Space Station indicate that sending more complex computer chips into space to pre-reduce the large data stream sent Earthbound could be the answer. But how well would the latest, most sensitive computing electronics fare in the harsh environment of outer space? ... > full story
Better way to detect food allergies (May 22, 2010) -- A chemical engineer believes he has a better way to diagnose such allergies. His new technology can analyze individual immune cells taken from patients, allowing for precise measurement of the cells' response to allergens such as milk and peanuts. ... > full story
Cassini heading to Saturn's Titan after tagging Enceladus (May 22, 2010) -- NASA's Cassini spacecraft is on its way to a flyby of Saturn's largest moon, Titan, after capturing some stunning images of Enceladus. One view shows the hazy outline of Titan behind Saturn's rings, with the dark curve of Enceladus at the bottom. ... > full story
NASA's Mars rovers set surface longevity record (May 22, 2010) -- NASA's Mars Exploration Rover Project will pass a historic Martian longevity record on May 20. The Opportunity rover will surpass the duration record set by NASA's Viking 1 Lander of six years and 116 days operating on the surface of Mars. The effects of favorable weather on the red planet could also help the rovers generate more power. ... > full story
Low-cost, ultra-fast DNA sequencing brings diagnostic use closer (May 22, 2010) -- Researchers show the viability of a novel, more efficient method to sequence DNA using nanopores. By doing it fast and inexpensively, this method brings routine use of DNA sequencing in medical diagnostics closer to reality. ... > full story
Hubble finds a star eating a planet (May 21, 2010) -- The hottest known planet in the Milky Way galaxy may also be its shortest-lived world. The doomed planet is being eaten by its parent star, according to observations made by a new instrument on NASA's Hubble Space Telescope, the Cosmic Origins Spectrograph (COS). The planet may only have another 10 million years left before it is completely devoured. ... > full story
Presence of chemical in smoker's breath indicates person has smoked in last three days (May 21, 2010) -- If you smoke, your breath contains 2,5-dimethylfuran. A team of Catalan researchers have proved that the presence of this chemical compound indicates that a person has smoked in the last three days. This substance does not appear in the breath of non-smokers, unless they have been in direct contact with tobacco smoke for a long time. ... > full story
