Could life survive on Mars? Yes, expert says Posted: 05 Jun 2010 02:00 PM PDT Researchers have discovered that methane-eating bacteria survive in a highly unique spring located on Axel Heiberg Island in Canada's extreme North. Microbiologists explain that the Lost Hammer spring supports microbial life, that the spring is similar to possible past or present springs on Mars, and that therefore they too could support life.

Scientists capture very moment blood flow begins Posted: 05 Jun 2010 02:00 PM PDT By capturing movies of both the blood and vasculature of zebrafish embryos, each less than two millimeters long, researchers have been able for the first time to see the very moment that blood begins to flow.

Autism finding could lead to simple urine test for the condition Posted: 05 Jun 2010 02:00 PM PDT Children with autism have a different chemical fingerprint in their urine than non-autistic children, according to new research. The researchers suggest that their findings could ultimately lead to a simple urine test to determine whether or not a young child has autism.

Gene related to aging plays role in stem cell differentiation Posted: 05 Jun 2010 02:00 PM PDT A gene shown to play a role in the aging process appears to play a role in the regulation of the differentiation of embryonic stem cells, according to new research.

Video game research project to help blind children exercise Posted: 05 Jun 2010 02:00 PM PDT Researchers have developed a motion-sensing-based tennis and bowling "exergame" that will help the visually impaired, especially children become more physically active.

A sense of humor helps keep you healthy until retirement age Posted: 05 Jun 2010 02:00 PM PDT A sense of humor helps to keep people healthy and increases their chances of reaching retirement age. But after the age of 70, the health benefits of humor decrease, researchers have found.

Mongooses pass traditions on to their young, too Posted: 05 Jun 2010 08:00 AM PDT For the passing on of traditions, it appears that an especially big brain isn't required. Even mongooses in the wild carry out traditions that are passed down from one generation to the next, according to new research.

New gene therapy proves effective in treating severe heart failure Posted: 05 Jun 2010 08:00 AM PDT Researchers have developed a new gene therapy that is safe and effective in reversing advanced heart failure. SERCA2a is a gene therapy designed to stimulate production of an enzyme that enables the failing heart to pump more effectively. In a Phase II study, SERCA2a injection through a routine minimally invasive cardiac catheterization was safe and showed clinical benefit in treating this patient population and decreasing the severity of heart failure.

Glaciers in Tibet were never really large Posted: 05 Jun 2010 08:00 AM PDT The Tibetan Plateau is the largest and highest mountain region on Earth with glaciers whose meltwater provides the water supply for more than 1.3 billion people through several of the largest rivers in Asia. Glaciers in Tibet have remained relatively small and have not been much larger than today for tens of thousands to hundreds of thousands of years back in time, according to new research.

Stroke prevention study in children with sickle cell anemia, iron overload stopped early Posted: 05 Jun 2010 08:00 AM PDT Researchers have stopped a clinical trial evaluating a new approach to reduce the risk of recurrent stroke in children with sickle cell anemia and iron overload because of evidence that the new treatment was unlikely to prove better than the existing treatment.

An extra driver behind the wheel Posted: 05 Jun 2010 08:00 AM PDT When the steering wheel starts vibrating strongly, your car is too close to the edge of the road. WayPilot, a new Norwegian product, helps to keep it where it should be in the driving lane.

Biomechanics of information: Going more miles per gallon with your brain Posted: 05 Jun 2010 08:00 AM PDT The hunting strategy of a slender fish from the Amazon is giving researchers more insight into how to balance the metabolic cost of information with the metabolic cost of moving around to get that information.

Drug induces a memory of safety in rat brains Posted: 05 Jun 2010 02:00 AM PDT Researchers have found a way to pharmacologically induce a memory of safety in the brain of rats, mimicking the effect of training. The finding suggests possibilities for new treatments for individuals suffering from anxiety disorders.

Oncologists fight leukemia with two-pronged therapy, clinical trials planned Posted: 05 Jun 2010 02:00 AM PDT Researchers have used an agent, called Oxi4503, to poison leukemia cells and destroy the blood vessels that supply the cells in mouse models of acute myelogenous leukemia, or AML. The researchers plan human tests of the drug later this year.

Cysts hold clues to pancreatic cancer; Detection and removal may lower cancer risk Posted: 05 Jun 2010 02:00 AM PDT Researchers have developed a method that could be used to predict whether pancreatic cysts are benign or are precursors to invasive cancer.

New cancer treatment? MM-111 antibody uses HER2 target to reach and block HER3 Posted: 05 Jun 2010 02:00 AM PDT Patients with HER2-positive cancers can have dramatic responses to HER2-targeted drugs but eventually develop resistance to the agents. With that problem in mind, researchers are testing a novel type of antibody called MM-111 in patients with HER2-positive disease who have progressed on standard therapy.

Making lake and stream conservation more effective Posted: 05 Jun 2010 02:00 AM PDT Scientists have developed a pioneering, comprehensive approach that makes conserving and managing freshwater lakes, streams and wetlands more integrated and effective.

Special care plan does not slow decline in patients with Alzheimer's, study finds Posted: 05 Jun 2010 02:00 AM PDT A special dementia care plan, involving regular assessments of patients with Alzheimer's disease in specialist memory clinics, does not slow functional decline compared with usual care, a new study finds.
