The Commons: Not Always A Tragedy
This research refutes a thrity-year-old assertion that human users of common resources will ultimately destroy the resource on which they depend. A review of specific examples shows that people are capable of managing resources particularly at the local level. Lessons from small scale examples can be used as a point of departure for managing resources on a global scale.

No More Running Blind In A Maze-The Laboratory Rat Genetic And Radiation Hybrid Map Is Here
An essential resource for understanding genetics in the rat, a primary model for human medical research, the completion of a high-density integrated genetic linkage and radiation hybrid map is a genome science landmark. The new maps allow researchers previously hampered by incomplete rat genetic infrastructure to connect disorders to their underlying genetic components and will give human geneticists an invaluable tool for pinpointing related human genes.

In Animal Groups, Scientists See Patterns That Could Predict The Future
Like teenage boys hanging out on a street corner, animals behave differently when they're in a large group than when they're by themselves. The mechanics and patterns of nature's aggregations - schooling fish, flocking birds or swarming insects - help understand how such groups behave in, and survive, trying conditions, says a University of Washington zoologist.

ALA/ATS Meeting Explores Gender Differences In Smoking And Lung Transplant Outcomes And Heart Attack Risk From Asthma Medication
New findings on the different reasons men and women smoke, lung transplant outcomes and gender, and the risk of heart attack from a common asthma medication in people with heart disease were discussed here today by an expert panel at the American Lung Association/American Thoracic Society International Conference.

First Trial Comparing Adderall To Ritalin For ADHD Shows It To Be Longer-Lasting, Equally As Effective
The first trial of comparable doses of Ritalin, the standard treatment for children with attention deficit/hyperactivity disorder (ADHD), and Adderall, another drug used to treat ADHD, has shown that Adderall lasts longer than Ritalin and is at least as effective. Results are reported by University at Buffalo researcher William R. Pelham in the April issue of Pediatrics.

NCAR Scientist's Observations Aid In Discovery Of Multiple Planets Orbiting A Sun-Like Star
Three planets have been found orbiting the star Upsilon Andromedae in the first discovery of multiple planets outside our solar system. NCAR scientist Timothy Brown was part of the team of eight scientists who observed the additional planets.

A new technique for visualising the three dimensional internal structure of an object will allow engineers to see exactly where cracks and faults have appeared and how well the structure has been built. The technique, being developed by Sonoscan, can provide an unparalleled 3D view of the internal features and defects of items such as integrated circuit packages, diamond coatings or ceramic discs.

Jefferson Scientists Find Link Between Learning And Preventing Alzheimer's
A new study in rats suggests that a stimulating, learning environment early in life might actually help ward off neurodegenerative diseases later. The findings indicate that nurture may be more influential than nature when it comes to the brain's resilience against injury.

Alcohol Consumption, Related Problems Among High-Risk College-Age Drinkers Can Be Slashed Using Brief Intervention
Using a technique that can be likened to defensive drinking, alcohol consumption and alcohol-related problems were significantly slashed among a group of high-risk college- drinkers using a brief, non-confrontational intervention treatment developed by University of Washington researchers.

Autoimmune Diseases May Be Triggered By Cells From Your Mother
Autoimmune diseases, in which the body attacks its own tissues, may in some cases be triggered by cells from your mother that have been lurking within you since you were in the womb. Researchers in Seattle found maternal cells in a man suffering from an autoimmune disease.

Important Genetic Marker For Alzheimer's Disease Questioned
A team of researchers from the University of Toronto, Boston University School of Medicine, Duke University and Vanderbilt University, has determined that recent findings suggesting a gene on chromosome 12 was a strong genetic risk factor for Alzheimer's disease cannot be replicated. The results of the investigation appear in the May issue of Nature Genetics.

However, New Hampshire, Maine, Massachusetts, and Rhode Island are still experiencing some problems with the quality of ground and surface water and the water in the Gulf of Maine.

Researchers Develop New Treatment For Hepatitis B And C As Nation Anticipates Surge In Number Of Cases
Scientists are studying new treatments to combat two viruses that cause chronic liver inflammation and are expected to become increasingly devastating over the next decade. Chronic hepatitis B is currently blamed for about 6,000 U.S. deaths a year; Hepatitis C for 10,000. Those numbers are expected to jump sharply - perhaps to as high as 30,000 hepatitis C deaths annually by the year 2010. The increased mortality is likely to be clustered in people of mid-adult years.
