Final moments of bee landing tactics revealed (January 2, 2010) -- When bees come into land they slow their speed as they approach, but what happens in the final instants before touch down? Using high speed video, scientists from Australia and Sweden have found that there are three stages to the final touch down: a quasi-hover, a stable hover 16mm from the surface and finally a gentle touch down. Using this approach, bees can land on surfaces ranging from the horizontal to completely inverted ceilings. ... > full story
Genomic differences identified in common skin diseases may lead to better treatments (January 2, 2010) -- Scientists have drilled down on the molecular nitty-gritty that distinguishes the two most common forms of inflammatory skin disease, atopic eczema and psoriasis. The researchers say that the ability to distinguish between the disorders' genetic and immunological signatures opens the door for more narrowly targeted therapies sorely needed by the millions of people afflicted worldwide. ... > full story
NASA's WISE space telescope jettisons its cover (January 2, 2010) -- NASA's recently launched Wide-Field Infrared Survey Explorer (WISE) opened its eyes to the starry sky Dec. 29, after ejecting its protective cover. Engineers and scientists say the maneuver went off without a hitch, and everything is working properly. The mission's "first-light" images of the sky will be released to the public in about a month, after the telescope has been fully calibrated. ... > full story
Bacterial protein mimics its host to disable a key enzyme (January 2, 2010) -- Helicobacter pylori infects up to 90 percent of people in the developing world and causes gastric ulcers and cancers of the gut. Now scientists have revealed a subterfuge used by the bacterium to trick stomach cells into playing along. By injecting a protein into the stomach lining that mimics a native protein but has its opposite effect, the bacterium shuts down a process that helps properly structure stomach tissue, scientists say. ... > full story
Explaining plasma motion around Saturn (January 2, 2010) -- Understanding the motion and source of the plasma around Saturn is important for understanding the dynamics of the magnetosphere. Researchers present a theory that describes plasma transport in Saturn's magnetosphere, including processes that add new mass to the plasma and those that remove momentum from the plasma without changing plasma mass. ... > full story
It's never too late to quit smoking and save your vision (January 2, 2010) -- Need a little extra incentive to kick the habit? Just in time for New Year's resolutions, a new study finds that even after age 80, smoking continues to increase one's risk for age-related macular degeneration (AMD), the leading cause of blindness in Americans over 65. ... > full story
Fast pace of glacier melt in the 1940s: lower aerosol pollution (January 1, 2010) -- In the 1940s Swiss glaciers were melting at an even-faster pace than at present, according to new research. This is despite the fact that the temperatures in the 20th century were lower than in this century. Researchers see the main reason for this as the lower level of aerosol pollution in the atmosphere. ... > full story
New research could advance research field critical to personalized medicine (January 1, 2010) -- It's the ultimate goal in the treatment of cancer: tailoring a person's therapy based on his or her genetic makeup. While a lofty goal, scientists are steadily moving forward, rapidly exploiting new technologies. Researchers report a significant advance in this field of research using a new chip that looks for hundreds of mutations in dozen of genes. ... > full story
New molecule identified in DNA damage response (January 1, 2010) -- In the harsh judgment of natural selection, the ultimate measure of success is reproduction. So it's no surprise that life spends lavish resources on this feat, whether in the courtship behavior of birds and bees or replicating the cells that keep them alive. Now research has identified a new piece in an elaborate system to help guarantee fidelity in the reproduction of cells, preventing potentially lethal mutations in the process. ... > full story
The cancer 'TRAP': protein may prevent cancer cell death (January 1, 2010) -- New research suggests that TNF-receptor associated protein-1 (TRAP-1) may prevent cancer cell death. ... > full story
Window opens into Moon's past volcanism (January 1, 2010) -- Lava tubes, underground cave-like channels through which lava once flowed, are commonly found on Earth. Scientists have debated whether these tubes could form on the Moon as well, but no studies have yet conclusively identified features that indicate the presence of lunar lava tubes. ... > full story
Student sleuths using DNA reveal zoo of 95 species in NYC homes -- and new evidence of food fraud (January 1, 2010) -- Two New York City high school students exploring their homes using the latest high-tech DNA analysis techniques discover a veritable zoo of 95 animal species surrounding them, in everything from fridges to furniture, from sidewalks to shipping boxes, and from feather dusters to floor corners. ... > full story
