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

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

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

Children Are Naturally Prone To Be Empathic And Moral (July 12, 2008) -- Children between the ages of seven and 12 appear to be naturally inclined to feel empathy for others in pain, according to researchers who used functional Magnetic Resonance Imaging (fMRI) scans to study responses in children. Researchers found that children, like adults, show responses to pain in the same areas of their brains. The research also found additional aspects of the brain activated in children, when youngsters saw another person intentionally hurt by another individual. ... > full story

Biological Marker For Alzheimer's Holds Promise For Earlier Diagnosis And Treatment (July 12, 2008) -- Researchers have found clear evidence that increases in the size of the brain ventricles are directly associated with cognitive impairment and Alzheimer's disease. Ventricles are fluid-filled cavities in the brain. The research shows the volume of the brain ventricles expands as surrounding tissue dies. ... > full story

Coming Epidemic Of Type 2 Diabetes In Young Adults (July 12, 2008) -- How will the epidemic of childhood obesity today affect the future health of Americans? As concern about children's health grows along with their waistlines, medical experts fear that the childhood obesity epidemic could lead to large numbers of younger adults developing type 2 diabetes, causing serious and lasting health complications for future generations of Americans. ... > full story

Problems Of Predicting Birthweights In Obese Mothers (July 12, 2008) -- Obesity is a risk to mother and baby, but American researchers have found a method that tackles the problem of predicting birth weights when mothers have a BMI of more than 30, making ultrasound measurements difficult at full term. They looked at 357 women with BMIs of up to 58 and compared them with 1,025 women who were not overweight. The results showed accurate and comparable results in all but the most obese mothers-to-be. ... > full story
