Discovery of how communication between cancer cells is controlled

The discovery, by scientists at Monash University and the Sloan Kettering Cancer Centre in New York, of how communication between cancer cells is controlled has promised new treatment options for malignant tumours.

Search for genes responsible for anxiety disorders

Increasing the activity of two enzymes better known for their role in oxidative stress metabolism turns normally relaxed mice into "Nervous Nellies," according to research conducted at the Salk Institute for Biological Studies and reported in the early online edition of Nature.

Researchers can now more accurately predict who will develop type 1 diabetes

In the process, they've also uncovered signs of a new protein that may forecast a more rapidly developing form of the disease. Together, these findings could help researchers screen patients for clinical trials that eventually may lead to a vaccine or cure for type 1 diabetes.

Scientists unravel complex mechanisms in the brain that regulate body weight

Scientists are one step closer to unraveling the complex mechanisms in the brain that regulate body weight. Working with mice -- whose appetites are controlled by systems very similar to those in humans – they have identified a specific type of neuron that is essential for feeding behavior.

Lack of sex could be a signpost to extinction

Researchers from Imperial College London believe that when species become asexual they could be on their way to extinction.

Scientists say there is less white matter in the frontal lobes of those who struggle with focusing

When it comes to focusing on a task amid distractions, some folks more than 60 years old are as mentally sharp as 22-year-olds. Others struggle. Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have shed some light on why that is.

New insights into how genetic mutations arise

Researchers at Stanford University have created a larger-than-normal DNA molecule that is copied almost as efficiently as natural DNA.

Natural blood sugar level lowering compound could lead to new drugs to treat type 2 diabetes

A carbohydrate isolated from the liver lowers blood sugar levels after it is injected into diabetic rats, according to research carried out by a team of experts at the University of Virginia Health System (UVHS).

Alien abduction may be all in the mind

New research presented at the Science Museum's Dana Centre, supports what scientists have long argued: that people who report contact with aliens have a psychological profile that might make them more susceptible to false memories.

Possible toxic damage from inhaled nanoparticles

A physicist and a medical researcher at the University of Leicester have received a grant of £100,000 from the Engineering and Physical Sciences Research Council to look at possible toxic damage from inhaled nanoparticles used for a range of everyday purposes.

Rate of weight gain, not the degree of fatness at any one time, which is the main predictor of future problems

Research published today indicates that the risk of heart disease in adulthood is more strongly related to how quickly children gain weight between the ages of two and eleven than their actual body weight at any particular age. Scientists believe this is linked to differences in insulin processing in later life.

Bouncing helicases possibly play a preventative role in keeping the genome intact

Researchers studying how proteins called helicases travel along strands of DNA have found that when the proteins hit an obstacle they snap back to where they began, repeating the process over and over, possibly playing a preventative role in keeping the genome intact.

Northwestern University move closer to new therapies for neurodegenerative disease

French neurologist Jean-Martin Charcot first described amyotrophic lateral sclerosis (ALS) in 1869, but, nearly 140 years later, little is known about the cause of the devastating neurodegenerative disease, and there is no cure.

Preventing bowel cancer in high risk families

Bowel cancer rates could be reduced by up to 80 per cent in people with a moderate family history of the disease by screening with colonoscopy, according to new research published in the British Medical Journal.

Simple urine test detects bladder cancer

According to Italian researchers a simple and accurate urine test can detect bladder cancer early and they say the test should be used on smokers and others prone to the disease.

Cancer drug may be effective for Alzheimer's

According to scientists at the Blanchette Rockefeller Neurosciences Institute and the Marine Biological Laboratory, a cancer drug may stimulate the production of proteins needed for long-term memory, suggesting the compound may a possible treatment for Alzheimer's disease

Common anthrax sampling methods need improvement

A research team from the National Nuclear Security Administration's Sandia National Laboratories has discovered that common anthrax sampling methods need improvement. The research shows that more deadly spores remain after decontamination than previously believed.

Middle-age people more likely to use complementary and alternative medicine

"Midlife adults entered adulthood at a time of more widespread use of complementary and alternative medicine (CAM) in the population and when public health policy was shifting attention toward individual responsibility for health and health promotion," said Joseph G. Grzywacz, Ph.D., and his colleagues, writing in the October issue of the Journal of Aging and Health.

Growth hormone illegal for off-label anti-aging use

Because of 1988 and 1990 amendments to the Food, Drug and Cosmetic Act, off-label distribution or provision of human growth hormone to treat aging or age-associated illnesses is illegal in the United States, according to a report in the Journal of the American Medical Association.
