Human experimental psychologists (also called cognitive psychologists) are in a curious position. Their subject — the human brain — is obviously the most complicated thing studied by any science.…

Scientists here have developed new dye-sensitized solar cells (DSSCs) that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light. Currently, the…

Limiting and labeling trans fats in food is not enough, according to Walter Willett, an epidemiologist and nutrition professor at the Harvard School of Public Health, who argues to food manufacturers…

Researchers at Johns Hopkins have found a way to overcome a major stumbling block to developing successful insulin-cell transplants for people with type I diabetes. Traditional transplant of the…

In order for the best baseball team to win, the National League would have to extend its season to 256 games say a pair of physicists at the Los Alamos national Laboratory in New Mexico. Because of…

Scientists at the U.S. Department of Energy's Argonne National Laboratory have identified a new technique for cleansing contaminated water and potentially purifying hydrogen for use in fuel cells,…

Insulin-dependent, or Type 1, diabetes is an autoimmune disease in which the body’s immune system attacks and destroys insulin and insulin-producing beta cells in the pancreas. Insulin is a hormone…

About twice as many Atlantic hurricanes form each year on average than a century ago, according to a new statistical analysis of hurricanes and tropical storms in the north Atlantic. The study…

Decades ago a gene was discovered that was linked to the susceptibility of multiple scleroris (MS). Since then, the search has been on to uncover the puzzling mix of genes, environment and immunity…

An enzyme found naturally in the blood could help protect soldiers against the effects of the deadly nerve agent sarin. The US military is funding a three-year study to evaluate the effectiveness of…

Autopsies usually point to a cause of death but now a study of brain tissue collected from people who committed suicide may explain an underlying cause of major depression and suicide. The…

"Human embryonic stem cells promise unrivalled opportunities. However, they are difficult, time-consuming and expensive to grow in the lab", says Dr. Chris Denning of Institute of Genetics, who is…

Twenty-one years after they first described a fatal genetic disorder in Missouri and Arkansas families, scientists at Washington University School of Medicine in St. Louis have linked the condition…

Excess nitrogen caused by fertilizers, animal waste, leaf litter, sewer lines, and highways is responsible for contaminating groundwater. It can also cause human health risks when found in drinking…

A new report from researchers at the University of Colorado and Stanford University speculates how unique, lineage-specific gene copy number expansions and contractions in humans may underlie traits…

A method for making instant steam, without the need for electricity, promises to be useful for tackling antibiotic resistant ‘superbugs’ like MRSA and C. difficile, as well as removing chewing gum…

Plant scientists have known for some time that genes from the maternal plant control seed development, but they have not known quite how. Scientists at the University of Oxford have paved the way…

Stem cells are generally assigned to one of two categories: embryonic or adult. Some researchers say that may be an oversimplification and a new University of Michigan study states that stem cells in…

Drinking malt liquor may put young adults at increased risk for alcohol problems and use of illicit drugs, particularly marijuana, according to a new study of malt liquor drinkers and marijuana use…

A recent UN study, Livestock's Long Shadow, basically says you can help the environment more by driving than walking. How so? Chris Goodall, author of How To Live a Low-Carbon Life explains.…
