New research on how skin cancer begins has identified adjacent cancer cells that scientists are calling "co-conspirators" in the genesis of melanoma, in findings that could someday hold the key to predicting, preventing and stopping this hard-to-treat cancer before it spreads.

More than eight of ten workers -- 85 percent -- rate workplace safety first in importance among labor standards, even ahead of family and maternity leave, minimum wage, paid sick days, overtime pay and the right to join a union, according to a new study. Despite widespread public concern about workplace safety, the study also found that the media and the public tend to pay closest attention to safety issues when disastrous workplace accidents occur.

The following are story tips from DOE/Oak Ridge National Lab.

A University of Connecticut (UConn) anthropologist says there is new evidence that nearly 12,000 years ago, feasts were used to celebrate burial of the dead, bringing about the world's first established communities.

Richard Lamb and his post doctoral fellow Virginie Mieulet, in the Faculty of Medicine & Dentistry, may be able to explain why proper nutrition is so vital in fighting infection. They have discovered an amino acid, called arginine, is required to let the body know that it's being attacked by an infection.

Anger, depression and helplessness are the main psychological responses being seen in response to the catastrophic Deepwater Horizon oil spill in the Gulf of Mexico, and they are likely to have long-lasting effects, according to an interview in Ecopsychology.

University of British Columbia researchers have led the development of a new "toolbox of MiniPromoters" for research and future therapies on brain, spinal cord and eye function.

I'm sure I told you that already! Older adults are more likely to have destination memory failures -- forgetting who they've shared or not shared information with, according to a new study led by Baycrest's Rotman Research Institute.

For competitive bicyclists with goals -- whether competing in the Tour de France or aiming for the podium at a local race -- faster cycling comes from training regimens based on various zones of exercise intensity. New research from exercise scientists at the University of New Hampshire has found that effective training regimens, which generally are created after expensive, time-consuming laboratory tests, can be developed from a relatively simple, do-it-yourself test.

A team of researchers at the University of Georgia and Glasgow University has now shown, for the first time, how one species of the parasites that cause African sleeping sickness evades the human innate defenses.

A new study led by Boston University School of Public Health epidemiologists has found that women who took over-the-counter decongestants during their pregnancies are less likely to give birth prematurely.

A team led by Massachusetts General Hospital scientists has developed a new microfluidic tool for quickly and accurately isolating neutrophils -- the most abundant type of white blood cell -- from small blood samples, an accomplishment that could provide information essential to better understanding the immune system's response to traumatic injury.

New study shows that oilsands mining and processing are polluting the Athabasca River with metals that are toxic at trace levels.

A distinct decline in horseshoe crab numbers has occurred that parallels climate change associated with the end of the last Ice Age, according to a study that used genomics to assess historical trends in population sizes.

Battery powered cars will play a major role in future of mobility. What was not known so far, was how environmentally friendly the manufacture, operation and disposal of the batteries are. Empa researchers have now calculated the ecological footprint of the most commonly used type, the lithium-ion battery. A car with a petrol engine must consume less than 4 liters of fuel per 100km or about 70 mpg (miles per gallon) in order to be as environmentally friendly as modern electric cars.

Gamblers who think they have a "hot hand," only to end up walking away with a loss, may nonetheless be making "rational" decisions, according to new research from University of Minnesota psychologists.

It's not just you -- everybody zones out when they're reading. For a new study published in Psychological Science, a journal of the Association for Psychological Science, scientists recorded eye movements during reading and found that the eyes keep moving when the mind wanders -- but they don't move in the same way as they do when you're paying attention.

In an effort to combat these startling findings, researchers at King's College London's Institute of Psychiatry describe a successful personality-based intervention for substance abuse delivered by teachers in the September 2010 issue of the Journal of the American Academy of Child and Adolescent Psychiatry.

An Iowa State University team of researchers, led by Bing Yang, has developed a type of hybrid proteins that can make double-strand DNA breaks at specific sites in living cells, possibly leading to better gene replacement and gene editing therapies.
