Above-normal weight alone does not necessarily increase short-term risk of death, U.S. data suggest Posted: 06 Jul 2012 08:47 PM PDT An evaluation of national U.S. data has found that extra weight is not necessarily linked with a higher risk of death. When compared to those with normal weight, people who were overweight or obese had no increased risk of death during a follow-up period of six years. People who were severely obese did have a higher risk, but only if they also had diabetes or hypertension.

Keeping the flu away: Synthetic protein activates immune system within two hours Posted: 06 Jul 2012 08:47 PM PDT Researchers may have found the secret to helping the immune system fight off the flu before it gets you sick. A new study finds that EP67, a powerful synthetic protein, is able to activate the innate immune system within just two hours of being administered.

World's fastest camera used to detect rogue cancer cells Posted: 06 Jul 2012 01:44 PM PDT Researchers report integrating the world's fastest camera with advanced microfluidics and real-time image processing to classify cells in blood samples. The new blood screening technology boasts a throughput of 100,000 cells per second which is approximately 100 times higher than conventional imaging-based blood analyzers. The technology performs real-time detection of extremely rare cells in a large sample of normal cells with high sensitivity and statistical accuracy in a short period of time.

Arctic warming linked to combination of reduced sea ice and global atmospheric warming Posted: 06 Jul 2012 01:42 PM PDT The combination of melting sea ice and global atmospheric warming are contributing to the high rate of warming in the Arctic, where temperatures are increasing up to four times faster than the global average, a new study has shown.

Spaceflight may extend the lifespan of microscopic worm Posted: 06 Jul 2012 07:55 AM PDT The effect of spaceflight on a microscopic worm -- Caenorhabditis elegans (C. elegans) -- could help it live longer. The discovery was made by scientists studying the loss of bone and muscle mass experienced by astronauts after extended flights in space.

Antibodies reverse type 1 diabetes in new immunotherapy animal study Posted: 05 Jul 2012 10:37 PM PDT Scientists have used injections of antibodies to rapidly reverse the onset of Type I diabetes in mice genetically bred to develop the disease. Moreover, just two injections maintained disease remission indefinitely without harming the immune system.
