AGU Adopts Position On Climate Change And Greenhouse Gases
Atmospheric concentrations of carbon dioxide and other greenhouse gases have substantially increased as a consequence of human activity.

Programmable Cells Open Window Of Opportunity For Gene Therapy
In the fast-paced world of genetics research, work conducted in Detroit has begun to unravel the mechanism that is responsible for the direction each cell takes in its development from the generic cells of the embryo to the specific cells of each tissue.

Study Indicates That Medicare Costs Are Higher -- And Survival Rate Is Better --At Major Teaching Hospitals Survive Climate Change
A study conducted by Duke University researchers has found that while it costs more to treat people for hip fractures and other conditions at major teaching hospitals, the survival rate is also higher among people initially treated at these facilities.

Natural Painkillers And Strong Antioxidants Found In Tart Cherries
The chemicals that give tart cherries their red color may relieve pain better than aspirin and may provide antioxidant protection comparable to commercially available supplements like vitamin E, according to Michigan State University researchers.

Encouraging Results In Preclinical Studies Of Parkinson's Disease Gene Therapy

Hunter College Biologist Marie Filbin Identifies Mechanism That Blocks All Inhibitors Of Nerve Regeneration; Breakthrough Reported In Neuron Magazine
Neurobiologist Marie T. Filbin, Distinguished Professor of Biological Sciences at Hunter College of the City University of New York, has made a research breakthrough that has important long-term therapeutic potential for victims of spinal cord injuries.

UNC Researchers Testing First In New Class Of AIDS Drugs
AIDS investigators at the University of North Carolina at Chapel Hill are testing the first of a new class of drugs that attacks HIV before it enters the cell and may prove effective for patients with drug-resistant HIV.

Study Finds Protein Clues To Early Embryo Development
In a study of life's beginnings, scientists at the University of North Carolina at Chapel Hill have moved a step closer to unraveling the biochemical mystery of embryogenesis, the process by which an egg cell transforms into an embryo.

Climate Model Predicts Wet Winters, Dry Summers For Northwest
Farming and snow skiing may not be the same in the Northwest if carbon dioxide levels double as projected by 2080, according to a scenario produced by a new regional climate change model.

New SafeNet System Lets Individual Safety Devices Actually Talk To Each Other
Safety systems have long preferred to stay in splendid paranoid isolation.

Ten Young Researchers Each Awarded $1 Million By McDonnell Foundation
(St. Louis, MO) - Ten early career researchers, whose work could shape our knowledge of the world around us, are now each the recipient of a $1 million research fellowship awarded to their sponsoring institution, by the McDonnell Foundation.

Superconductors See The Light At Shorter Wavelengths
A University of Rochester scientist and his Russian colleagues have developed a superconducting device capable of detecting light at wavelengths that were previously off- limits to the materials, with remarkable speed and sensitivity.

Women With PCOS Also Have Higher Rates Of Diabetes
A new study shows that women with Polycystic Ovary Syndrome (PCOS) have a much higher risk for impaired glucose tolerance levels which is a risk factor for diabetes.

New Findings On Lung Transplantation And Esophageal Cancer: Incidence Of Chronic Rejection Less For Lung Recipients Who Receive Bone Marrow
Simultaneous infusion of donor bone marrow at the time of lung transplantation significantly reduced the incidence of obliterative bronchiolitis, the telltale marker for chronic rejection that prevents air exchange in the lung's bronchioles, researchers from the University of Pittsburgh report at the Society of Thoracic Surgeons Annual Meeting.

How To Feed A Black Hole ?
Do black holes wipe up all material from their surroundings?

C-Sections Before Labor And Rupture Of Membranes Reduce The Risk Of Maternal-Infant HIV Transmission By Half
The largest, most comprehensive analysis of its kind has found that pregnant women infected with HIV can reduce the risk of transmitting the virus to their infants by about 50 percent if they deliver by elective cesarean section--before they have gone into labor and before their membranes have ruptured, according to a study led by a researcher at the National Institute of Child Health and Human Development (NICHD).

Additive Increases Life, Lowers Costs Of Concrete Bridge Decks
Penn State researchers have found that a commercially available additive can potentially double the life and lower the long term costs of concrete bridge decks by enhancing resistance to water, corrosion and de-icing salt.

Forecasting Killer Heat: UD Systems Predict Deadly Weather Worldwide
Heat kills, claiming thousands of lives each summer, but new UD technology offers up to 60 hours' advance warning of such deadly weather, which could prove particularly important in the 21st century, if global warming predictions come to pass. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
