Researchers studied the drinking habits of 9,833 15- to 16-year-olds in the North West of England, finding that excessively low cost alcohol products and illicit purchase are strongly related to harmful underage drinking.

More research is required to establish whether Chinese herbal medicines can reduce the likelihood of developing diabetes, according to researchers. Although herbal medicines are widely used in Asian countries to treat pre-diabetes (impaired glucose tolerance or IGT), the precursor of the disease, researchers say there is still not enough hard scientific evidence to confidently recommend their...
Scientists have successfully produced liver cells from patients' skin cells opening the possibility of treating a wide range of diseases that affect liver function.
Adults who develop shingles are about 30 percent more likely to have a stroke within a year than adults who don't have shingles. When the shingles infection involves the skin around the eye and the eye itself, the risk of stroke may increase more than four-fold. Shingles is a painful skin rash caused by the same virus that causes...
Researchers have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. The resulting biomaterial could be used to make optically active structures, such as optical diffusers for solar panels.
Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. Researchers are developing a nuclear energy source that is smaller, lighter and more...
Results from a new study suggest that premature aging of the immune system appears to play a role in the development of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease. The researchers found that thymic malfunction occurs simultaneously with motor neuron dysfunction, both in laboratory mice bred to mimic amyotrophic lateral sclerosis and in humans suffering from the...
You must go back 15 million years to find carbon dioxide levels as high as they are today, Earth scientists report. "The last time carbon dioxide levels were apparently as high as they are today and sustained at those levels, global temperatures were five to 10 degrees Fahrenheit higher than they are today," said Aradhna Tripati, UCLA assistant professor of Earth and Space Sciences and lead...
Just being around green products can make us behave more altruistically, a new study in Psychological Science has found. But buying those same products can have the opposite effect. Researchers found that buying green can lead people into less altruistic behavior, and even make them more likely to steal and lie than after buying conventional...
Robots equipped with wireless and sensing capabilities are available for use in the home. But the safety and privacy risks of these devices are not yet adequately addressed, according to a new study.
Researchers have engineered more viable heart repair patches from mixed stem cells. The patches beat spontaneously, can be electronically paced and have pre-formed blood vessels that connect to a rodent's heart circulation.
An international team of paleontologists has discovered a new species of mammal that lived in China's Liaoning Province 123 million years ago. This remarkably well preserved fossil offers important insight into how the mammalian middle ear evolved. Such exquisite dinosaur-age mammals provide evidence of how developmental mechanisms have impacted the evolution of the earliest...
Australian scientists have found that the bacterium Cupriavidus metallidurans catalyzes the biomineralization of gold by transforming toxic gold compounds to their metallic form using active cellular mechanism.
Light readily bounces off obstacles in its path. Some of these reflections are captured by our eyes, thus participating in the visual perception of the objects around us. In contrast to this usual behavior of light, researchers have implemented for the first time a one-way structure in which microwave light flows losslessly around obstacles or defects. This concept, when used in lightwave...
Archaeologists have released an artist's impression of what a second stone circle found a mile from Stonehenge might have looked like. The drawing shows the sensational discovery of "Blue Stonehenge" by a team led by UK archaeologists on the West bank of the River Avon last...
A new study shows that the brain plays a key role in mediating resveratrol's anti-diabetic actions, potentially paving the way for future orally delivered diabetes medications that target the brain.
An increase in cases of a rare type of head and neck cancer appears to be linked to HPV, or human papillomavirus, according to a new study.
At 7:30 a.m. EDT on Oct. 9, a two-ton rocket body will slam into a crater near the moon's south pole. By studying the resulting plume of gas and dust, scientists hope this grand experiment will confirm the presence of ice in permanently shadowed craters at the lunar poles. A NASA Goddard Space Flight Center visualization team previewed the lunar...

Plinian eruptions are rare but highly explosive volcanic eruptions, which are often preceded by quite short periods of tectonic activity. Researchers in Germany have now been able experimentally to determine the speed at which the molten rock in the magma chamber rises to the...
A Japanese research group has found that ATP plays a key role in transmitting temperature information from skin keratinocytes to afferent sensory neurons.
Recent bank failures point to the continuing need for vigilance by regulators and investors. Now, a new report discusses the possibility of an early-warning system that spots the outliers before they fail.
Astronomers in Canada have released footage of a meteor that was approximately 100 times brighter than a full moon. The meteor lit up the skies of southern Ontario two weeks ago and Western astronomers are now hoping to enlist the help of local residents in recovering one or more possible meteorites that may have crashed in the area of Grimsby,...
Researchers have identified genes which may influence the onset age of Parkinson's disease. The findings are the first to identify genes contributing to the variation in onset age and may help identify mechanisms and therapeutic targets capable of delaying symptoms.
The intense exchanges that human mothers share with their newborn infants may have some pretty deep roots, suggests a study of rhesus macaques.
The role of the forests is assumed to increase in the future, as an important buffer of climate change and increasing carbon dioxide concentrations. So-called Earth system models, computer systems making predictions for the globe, estimate that this effect can be very large. However, new research results, based on measurements at hundreds of European forests, indicate that predicted effects by...
