Unusual source of ocean water contamination may rewrite environmental textbooks
A team of researchers may rewrite environmental textbooks after uncovering evidence that a saltwater marsh is a source of fecal bacteria contaminating one of California's most popular beaches.

World's largest scientific society providing scientific publications to Canadian academic research institutions
The American Chemical Society has reached an agreement with the Canadian National Site Licensing Project that gives academic research institutions across Canada access to the entire catalogue of ACS Web Editions, the online version of ACS scientific journals.

New satellite study shows vegetation increases in North America
An analysis of vegetation growth in North America between 1982 and 1998 using satellite observations indicates a significant increase in the rate at which carbon is being taken up by plants, according to a new study led by the University of Colorado at Boulder.

A quasar's identity may simply be in the eye of the beholder
Using NASA's Chandra X-ray Observatory, astronomers have made the first detailed study of a quasar shrouded in clouds of gas and dust.

One hour of grass cutting equals 100 miles worth of auto pollution
The air pollution from an hour of mowing the lawn is about the same as that from a 100-mile automobile ride, according to a report in the June 1 issue of Environmental Science & Technology, a journal of the American Chemical Society, which recommends using catalytic converters on mowers.

Fragmentation linked to stress in birds
Amazon forest birds are particularly sensitive to habitat fragmentation -- even patches as big as 250 acres are missing many species -- but no one knows why.

Rationale for rationing no longer compelling
The Oregon Health Plan is regarded as having pioneered explicit, systematic and open rationing of health care by denying access to some services.

Pet trade wrong: Poaching major threat to parrots
While the pet trade and conservation biologists agree that parrots are threatened by habitat loss, they disagree about the effects of poaching.

First in New York: PMDD and postpartum depression symposium for the general public
For the first time, New Yorkers will be able to attend a women's symposium that addresses mood changes associated with pregnancy and postpartum; premenstrual syndrome and premenstrual dysphoric disorder (PMDD); perimenopause and menopause.

Hang up the phone, or hang up the keys
In 1997, Drs. Donald Redelmeier and Robert Tibshirani published what has become the most widely cited scientific study on the link between cellular telephones and motor vehicle collisions.

The link between abuse during pregnancy and low birth weight
Abuse during pregnancy is considered a potentially modifiable risk factor for low birth weight (<2500 g).

Early results of Web site-based health management interventions study outlined
Health professionals attending the recent American Occupational Health Conference in San Francisco got a glimpse of the year-to-date findings of a randomized two-year study measuring the effectiveness of Web site-based health management interventions.

Tropical glaciers formed while earth was giant snowball
Glacial deposits that formed on tropical land areas during snowball Earth episodes around 600 million years ago, lead to questions about how the glaciers that left the deposits were created.

Human brain has unsuspected oxygen reserve, challenging previous theories
Scientists at Washington University School of Medicine in St. Louis have discovered that, unlike many other animals, humans have a reserve of oxygen in the brain.

New smoking cessation tool being studied
Smokers may eventually have another available tool - an oral nicotine solution that can be added to their favorite beverage - to help them kick the habit, according to Dr.

Babies have a different way of hearing the world by listening to all frequencies simultaneously
The world apparently sounds very different to infants than it does to adults.

Remote sensing study defines "edgy" cities
In a preliminary analysis of 12 cities using data from NASA's ASTER satellite, researchers have found three significant configurations of urban development that they believe can be used to classify cities by their growth and density patterns.

Fragmentation may limit songbird sex lives
Researchers have discovered a surprising factor in the decline of songbirds in North America: forest fragmentation may put a cramp in their sex lives.

Melting glaciers signal global warming
In only seven months of monitoring, researchers using the ASTER instrument on NASA's Terra Spacecraft have already seen melting in glaciers all over Earth, which provides some solid evidence -- or liquid evidence -- for global warming.

Natural immune response reduces nerve damage; may lead to improved treatment for spinal cord injury
In a series of animal experiments, scientists show for the first time that damage to the central nervous system causes the body to mount an immune reaction against itself that actually protects neurons from further damage.

Vegetation key to accurate climate modeling
Linking vegetation models to climate models when approximating the Earth's past and future climates may make climate predictions more accurate and could provide a better picture of the effects of global warming on the Earth, according to Penn State researchers.

Most women are not confrontational when faced with sex harassment, Yale study shows
Women like to believe they would report or confront someone who was sexually harassing them, but when faced with an actual situation, out of fear they rarely voice objections.

Disturbance can benefit some rare forest plants
While human disturbances can destroy ecosystems, new research shows that a little disturbance can be good for forest plants with small ranges.

Kyoto's global warming controls could harm forests
To help reduce global warming, the Kyoto Protocol encourages countries to remove carbon dioxide from the atmosphere by planting more trees.
