Superfast Vocal Muscles In Songbirds: Hundred Times Faster Than Blink Of An Eye (July 12, 2008) -- Certain songbirds can contract their vocal muscles 100 times faster than humans can blink an eye -- placing the birds with a handful of animals that have evolved superfast muscles, researchers found. ... > full story
Detecting Early Forms Of Cancer By Analyzing Structure of Specific Sugar Molecules (July 12, 2008) -- Scientists have developed a system which can pinpoint potential "biomarkers" of early forms of cancer, by looking at structures of specific sugar molecules which are attached either to proteins of cancerous cells or to proteins involved in the host response. The availability of such cancer biomarkers could also allow disease progression and response to therapy to be monitored more easily and accurately than is currently possible. ... > full story
Decadent, Convenient Banana Dessert Débuted At Food Expo (July 12, 2008) -- Who doesn't like a banana split? Fresh fruit, three flavors of ice cream and chocolate syrup. Yum. That vision was the subjective basis for a new product developed by a team of Virginia Tech students -- frozen bite-sized slices of banana filled with creamy chocolate, vanilla, or strawberry non-fat frozen yogurt and enrobed in dark chocolate. Called "Banana Splitters," the new confection is packaged as nine individual pieces -- three of each flavor -- in a sleeve, six sleeves in a package to be available next to the ice cream and other frozen goodies. ... > full story
Cool, Air Blown Under Football Shoulder Pads Reduces Body Temperature And Heart Rate, Research Finds (July 12, 2008) -- Cool, dry air flowing between the athlete and their football pads reduces core body temperature and heart rate dramatically, thereby reducing the likelihood of heat-related illness, a new study shows. The study found that air forced under the uniform, rather than misted, cool air blown on to the uniform, could be a helpful measure to avoid heat-related illness in football players. ... > full story
Coal-generated Carbon Dioxide Captured In Australia -- A First (July 12, 2008) -- In a first for Australia, carbon dioxide has been captured from power station flue gases in a post-combustion-capture pilot plant at Loy Yang Power Station in Victoria's Latrobe Valley. ... > full story
Learning Suffers If Brain Transcript Isn't Transported Far Out To End Of Neurons (July 12, 2008) -- Neuroscientists have solved a mystery that lies at the heart of human learning, and they say the solution may help explain some forms of mental retardation as well as provide clues to overall brain functioning. ... > full story
Model For Automated, Wearable Artificial Kidney Designed (July 12, 2008) -- Two researchers have developed a design for an automated, wearable artificial kidney, or AWAK, that avoids the complications patients often suffer with traditional dialysis. The peritoneal-based artificial kidney is "bloodless" and reduces or even eliminates protein loss and other dialysis-related problems. ... > full story
Unsuspected Gene Mutation Found For Atrial Fibrillation (July 12, 2008) -- Researchers have found a gene mutation linked to one family's hereditary form of atrial fibrillation. The study was based on a large family with an inherited form of atrial fibrillation in 11 relatives. Investigators discovered the defective gene by scanning the entire human genome, comprised of more than 30,000 genes. ... > full story
Insect Warning Colors Aid Cancer And Tropical Disease Drug Discovery (July 12, 2008) -- Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers. Such clues could speed drug discovery and provide insight into the ecological relationships between tropical-forest plants and insects that feed on them. ... > full story
Cadaver Tissue Fails Nearly 25 Percent Of The Time In Young ACL Reconstructions (July 12, 2008) -- Choosing the best replacement ligament for surgery is one key to ACL reconstruction success. A new study found that with a failure rate of almost 24 percent, the use of cadaver replacement ligaments may not be the best choice for young, athletic patients. ... > full story
Molecular Motor Works By Detecting Minute Changes In Force (July 12, 2008) -- Researchers discovered that the activity of a specific family of nanometer-sized molecular motors called myosin-I is regulated by force. The motor puts tension on cellular springs that allow vibrations to be detected within the body. This finely tuned regulation has important implications for understanding a wide variety of basic cellular processes. ... > full story
Researchers Detect Fake Art From Originals (July 12, 2008) -- As museums continue to digitize their art collections, it becomes increasingly easier for paintings to be forged. Scientists are now working on a digital system to help detect original works from counterfeit ones. ... > full story
