Between the cataclysmic impact that created the Moon around 4.5 billion years ago and the first evidence of life 3.8 billion years ago, there may have been long periods during which life repeatedly spread across the globe, only to be nearly annihilated by the impact of large asteroids.

Jefferson scientists suggest potential mechanism underlying the origin of colon cancer
Researchers may have figured out one way in which a mutation in a gene thought to be responsible for colon cancer may actually cause the disease.

Molecular insight into wound healing
Scientists have discovered a critical protein involved in skin inflammation.

Magnetic tag lets scientists track stem cells in living rat
Using tiny rust-containing spheres to tag cells, scientists from Johns Hopkins and elsewhere have successfully used magnetic resonance imaging to track stem cells implanted into a living animal, believed to be a first.

Genetic mutations linked to breast, ovarian cancer may be underestimated
Mutations in key genes which could make some women more susceptible to breast and ovarian cancer may be more widespread than researchers had previously believed.

Antarctic mud reveals ancient evidence of global climate change
Scientists concerned about global warming are especially troubled by dramatic signs of climate change in Antarctica - from rapidly melting glaciers to unexplained declines in penguin populations.

Modeling human lung cancer
Independent research groups from Sloan-Kettering and MIT have developed mouse models of human lung cancer that shed new light on the initiation and maintenance of the most prevalent form of this disease.

Lungs develop better in kids who move away from pollution
When children living under polluted, hazy skies move away to communities with cleaner air, their lungs begin to grow more quickly, according to a study by researchers at the Keck School of Medicine of USC.

People with chronic health problems are heaviest users of medical care, but system not organized to meet their needs
The heaviest users of the medical care system are the 128 million Americans who suffer from chronic health conditions, disabilities, or functional limitations.

Universal extractant removes multiple radioactive elements from nuclear waste in one step
Scientists from the DOE's Idaho National Engineering and Environmental Laboratory and Khlopin Radium Institute in Russia received an $800,000 three-year grant from DOE's Environmental Management Science Program to study and improve their solution to separating out much of the radioactive material in nuclear waste.

Russian universities receive US funding to improve basic scientific research capabilities
The U.S Civilian Research and Development Foundation and Russian Ministry of Education announced Basic Research and Higher Education (BRHE) program awards of $1 million each to four Russian universities.

Stern of AAAS receives Presidential Award for Excellence

New fund brings children from Europe for lifesaving surgery
NYU Medical Center has partnered with Nowy Dziennik - Polish Daily News in New York to raise money to bring children with brain tumors to the US for surgery that can not be provided in their home country .

Iron supplements help African children learn to walk and talk
Researchers at the Johns Hopkins Bloomberg School of Public Health found that iron supplementation improved motor and language development in rural African preschoolers, while an anti-helminth treatment had only a slight positive effect on both motor and language development.

Brain damage from HIV, Alzheimer's, may have similar mechanism, SFVAMC researchers say
Both HIV and Alzheimer's disease can damage the brain, but most people think the similarity between the two ends there.

Near-death experience remains a mystery
Authors of a Dutch study in this week's issue of THE LANCET conclude that medical explanations cannot account for the phenomonen known as near-death experience (NDE).

Fogarty International Center announces new research training program in genetics
The Fogarty International Center (FIC) of the National Institutes of Health (NIH) announces a new research training program to support international collaborations in human genetic sciences.

Scientists identify key risk factor for canine arthritis: Method may eventually give humans similar warning
Drawing upon an international database of some 16,000 dogs, researchers at the University of Pennsylvania have pinpointed what's believed to be the first solid predictor, in any species, of future arthritis.
