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…
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…
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…
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…
DNA, that marvellous, twisty molecule of life, has an alter ego, research at the University of Michigan and the University of California, Irvine reveals…
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…
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…
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…
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…
