Flying fish glide as well as birds, researchers find (September 11, 2010) -- How well do flying fish fly? This is the question that puzzled researchers in South Korea. Measuring aerodynamic forces on dried darkedged-wing flying fish in a wind tunnel, they discovered that flying fish glide better than insects and as well as birds. The fish also derive an aerodynamic advantage from gliding close to the water's surface to cover distances as great as 400 meters. ... > full story
Misfolded neural proteins linked to autism disorders (September 11, 2010) -- Scientists have identified misfolding and other molecular anomalies in a key brain protein associated with autism spectrum disorders. ... > full story
E. coli engineered to produce biodiesel (September 11, 2010) -- New research is shedding light on how to alter the genetic makeup of E. coli to produce biodiesel fuel derived from fatty acids. ... > full story
New study singles out factors linked to cognitive deficits in type 2 diabetes (September 11, 2010) -- Older adults with diabetes who have high blood pressure, walk slowly or lose their balance, or believe they're in bad health, are significantly more likely to have weaker memory and slower, more rigid cognitive processing than those without these problems, according to a new study. ... > full story
Yikes! Sensor measures yoctonewton forces fast (September 11, 2010) -- Physicists have used a small crystal of ions (electrically charged atoms) to detect forces at the scale of yoctonewtons. Measurements of slight forces -- one yoctonewton is equivalent to the weight of a single copper atom on Earth -- can be useful in force microscopy, nanoscale science, and tests of fundamental physics theories. ... > full story
Energy drinks may give young sports teams an edge, study says (September 11, 2010) -- Consuming energy drinks during team sports could help young people perform better, a new study suggests. ... > full story
Moonstruck primates: Owl monkeys need moonlight as much as a biological clock for nocturnal activity (September 11, 2010) -- Anthropologists have shown that environmental factors, like temperature and light, play as much of a role in the activity of traditionally nocturnal monkeys as the circadian rhythm that regulates periods of sleep and wakefulness. ... > full story
Appetite hormones may predict weight regain after dieting (September 11, 2010) -- Many people have experienced the frustration that comes with regaining weight that was lost from dieting. According to a new study, the levels of appetite hormones in the body prior to dieting may serve as a predictor of weight regain after dieting. ... > full story
Research shows continued decline of Oregon's largest glacier (September 11, 2010) -- Researchers have returned to Collier Glacier for the first time in almost 20 years and found that the glacier has decreased more than 20 percent from its size in the late 1980s. The findings are consistent with glacial retreat all over the world and provide some of the critical data needed to help quantify the effects of global change on glacier retreat and associated sea level rise. ... > full story
Computer models suggest treatments for fractures that won't heal (September 11, 2010) -- New models, reinforced by in vivo experimentation, show why 5-10 percent of bone fractures don't heal properly, and how these cases may be treated to restart the healing process. Results of the model may benefit the aging population in which the occurrence of bone fractures is expected to rise substantially in the near future. ... > full story
Micro rheometer is latest 'lab on a chip' device (September 11, 2010) -- Researchers have demonstrated a micro-miniaturized device that can make complex viscosity measurements -- critical data for a wide variety of fields dealing with things that have to flow -- on sample sizes as small as a few nanoliters. ... > full story
New CCTV technology to help prevent terror attacks (September 11, 2010) -- Numerous CCTV systems are in use in public places which have the capacity to gather large amounts of image material. For the time being, however, there are no effective ways to analyze the mass of video data automatically and recognize potential risk situations in advance. A new European research project is aimed at developing IT solutions to this end. ... > full story
