Researchers discover root cause of blood vessel damage in diabetes

A key mechanism that appears to contribute to blood vessel damage in people with diabetes has been identified by researchers at Washington University School of Medicine in St. Louis…

More frequent drought likely in eastern Africa

— 18:37 GMT | Environment

The increased frequency of drought observed in eastern Africa over the last 20 years is likely to continue as long as global temperatures continue to rise, according to new research published in Climate Dynamics…

Fast growth, low defence - plants facing a dilemma

— 18:34 GMT | Biology

Plants are attacked by a multitude of insects and mammals. As defence against these herbivores they developed complex defence mechanisms over the course of evolution: spines, thorns, leaf hairs and a number of toxic chemical substances. For decades it has been controversially discussed whether the production of defence traits incurs costs to the plants. Now, using a new method the ecologists and plant biologists of the University of Zuerich together with their American colleagues demonstrate these costs accurately in a Proceedings of the Royal Society article…

Study: African-American men say doctor visits are often a bad experience

— 18:31 GMT | Health

A majority of African American men said they do not go to the doctor because visits are stressful and physicians don't give adequate information on how to make prescribed behaviour or lifestyle changes, a new University of Michigan study shows…

Powerful 3-D X-rays for kids in braces should be the exception, not the rule

— 18:28 GMT | Health

Some orthodontists may be exposing young patients to unnecessary radiation when they order 3-D X-ray imaging for simple orthodontic cases before considering traditional 2-D imaging, suggests a paper published by University of Michigan faculty…

Genetic clues to compulsive, self-injurious behaviour in rare childhood disorder

— 18:22 GMT | Health

Research from the University of California, San Diego School of Medicine provides new clues for the compulsive behaviour and cognitive defects associated with a rare childhood neurological disease called Lesch-Nyhan Disease (LND). Two pathways found to be defective in LND are known to be associated with other neurodegenerative disease, such as Alzheimer's and Parknson's diseases, suggesting common causes of cognitive and behavioural defects in these neurological disorders…

A new appreciation of the ecology-evolution dynamic

— 18:19 GMT | Environment

Ecology drives evolution. In today's issue of the journal Science, UC Davis expert Thomas Schoener describes growing evidence that the reverse is also true, and explores what that might mean to our understanding of how environmental change affects species and vice-versa…

Study finds presence of peers heightens teens' sensitivity to rewards of a risk

— 18:16 GMT | Health

It is well known that teenagers take risks - and that when they do, they like to have company. Teens are five times more likely to be in a car accident when in a group than when driving alone, and they are more likely to commit a crime in a group…

New research traces evolutionary path of multidrug-resistant strep bacteria

— 18:13 GMT | Health

Despite penicillin and the dozens of antibiotics that followed it, streptococcus bacteria have remained a major threat to health throughout the world. The reason: the superb evolutionary skills of this pathogen to rapidly alter its genetic makeup. In a landmark paper published this week in Science, scientists from Rockefeller University and the Sanger Institute have used full genome sequencing to identify the precise steps in the molecular evolution of Streptococcus pneumoniae. Their research shows the changes the genome of this bacterium has undergone in time and during its massive geographic spread over the globe…
