Carbon Dioxide Higher Today Than Last 2.1 Million Years Posted: 21 Jun 2009 02:00 PM PDT Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the Earth's cycles of cooling and warming.

Newly Discovered Interferon Response May Offer Early Control Of H5N1 Influenza Virus Posted: 21 Jun 2009 02:00 PM PDT Researchers suggest that the cell-signaling protein, interferon type 1, reduced H5N1 influenza virus replication in mice and may offer some degree of protection in the early stages of infection.

Brain Detects Happiness More Quickly Than Sadness Posted: 21 Jun 2009 02:00 PM PDT People make value judgments about others based on their facial expressions. A new study shows that -- after looking at a face for only 100 milliseconds -- we can detect expressions of happiness and surprise faster than those of sadness or fear.

Three To Six Months To Lose Weight Gained In Pregnancy Is Normal Posted: 21 Jun 2009 02:00 PM PDT Once the baby arrives, many new mothers want to return to their former weight quickly -- just like film stars who appear in the media in bikinis just weeks after giving birth. But according to new research, women should not put themselves under too much pressure straight away. Researchers warn that overdoing early weight loss attempts could have a negative impact on breastfeeding.

Computer Idle? Now You Can Donate Its Time To Find A Cure For Major Diseases Posted: 21 Jun 2009 02:00 PM PDT Not using your computer at the moment? You can now donate your computer's idle time to cutting-edge biomedical research aimed at finding a cure for HIV, Parkinson's, arthritis, and breast cancer.

Neural Noise Created During Binocular Rivalry Posted: 21 Jun 2009 02:00 PM PDT Neural "noise" may cause you to miss important changes in your environment when you are concentrating on something else, new research indicates.

Sunspots Revealed In Striking Detail By Supercomputers Posted: 21 Jun 2009 08:00 AM PDT In a breakthrough that will help scientists unlock mysteries of the Sun and its impacts on Earth, an international team of scientists led by the National Center for Atmospheric Research has created the first-ever comprehensive computer model of sunspots. The resulting visuals capture both scientific detail and remarkable beauty.

Dramatic Outcomes In Prostate Cancer Study Posted: 21 Jun 2009 08:00 AM PDT Two patients whose prostate cancer had been considered inoperable are now cancer free thanks in part to an experimental drug therapy that was used in combination with standardized hormone treatment and radiation therapy. The men were participating in a clinical trial of an immunotherapeutic agent called MDX-010 or ipilimumab.

Beating The Radar: Getting A Jump On Storm Prediction Posted: 21 Jun 2009 08:00 AM PDT Satellite observation of cloud temperatures may be able to accurately predict severe thunderstorms up to 45 minutes earlier than relying on traditional radar alone, say researchers.

Rare Disorder Gives Modelers First Glimpse At Immune System Development Posted: 21 Jun 2009 08:00 AM PDT Children born without thymus glands have given researchers a rare opportunity to watch as a new immune system develops its population of infection-fighting T-cells. Researchers tracked three young patients after thymus tissue transplantation to measure the growth of a T cell population -- with all of its diversity -- and learn about regulation mechanisms.

Scientists Use High-pressure 'Alchemy' To Create Nonexpanding Metals Posted: 21 Jun 2009 08:00 AM PDT By squeezing a typical metal alloy at pressures hundreds of thousands of times greater than normal atmospheric pressure, scientistshave created a material that does not expand when heated, as does nearly every normal metal, and acts like a metal with an entirely different chemical composition.

New Method To Study Gambling Addictions Developed Posted: 21 Jun 2009 08:00 AM PDT Researchers have created the world's first animal laboratory experiment to successfully model human gambling. The advance will help scientists develop and test new treatments for gambling addictions, a devastating condition that affects millions worldwide.

New Light Shed On 'Dark' Gamma-ray Bursts Posted: 21 Jun 2009 02:00 AM PDT Gamma-ray bursts are the universe's biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away. Yet, for more than a decade, astronomers have puzzled over the nature of so-called dark bursts, which produce gamma rays and X-rays but little or no visible light. They make up roughly half of the bursts detected by NASA's Swift satellite since its 2004 launch.

New Supplement May Help Slow Sight Loss In Elderly Posted: 21 Jun 2009 02:00 AM PDT Academics have helped develop an antioxidant supplement which may slow down sight loss in elderly people. The supplement may help those affected by the leading cause of blindness in the Western World, a five-year research program has found.

Toward New Drugs That Turn Genes On And Off Posted: 21 Jun 2009 02:00 AM PDT Scientists are reporting an advance toward development of a new generation of drugs that treat disease by orchestrating how genes in the body produce proteins involved in arthritis, cancer and a range of other disorders. Acting like an "on-off switch," the medications might ratchet up the production of proteins in genes working at abnormally low levels or shut off genes producing an abnormal protein linked to disease.

Statins Don't Lower Risk Of Pneumonia In Elderly, Study Shows Posted: 21 Jun 2009 02:00 AM PDT Popular cholesterol-lowering statin drugs like Lipitor (atorvastatin) don't lower the risk of pneumonia, according to a new study. Prior research based on automated claims data had raised some hope -- and hype -- for statins to prevent and treat infections including pneumonia. But using medical records for more detailed information, the researchers found pneumonia risk was higher (26 percent) in people using a statin than in those not using any.

Banning Certain Fishing Gear Can Help Save Reefs From Climate Change Posted: 21 Jun 2009 02:00 AM PDT Banning or restricting the use of certain types of fishing gear could help the world's coral reefs and their fish populations survive the onslaughts of climate change, experts say.

Insects' Sex Scents Can Save Lives Posted: 21 Jun 2009 02:00 AM PDT By identifying and also finding methods to prepare the substances, pheromones, that certain insects secret either to attract to them other individuals of the same species, potential sex partners, or to warn each other about enemies, scientists can save many human lives primarily in the third world.

Nutrient Delivery To The Gulf Of Mexico Among Highest Ever Measured Posted: 19 Jun 2009 09:00 PM PDT Spring nutrient delivery to the northern Gulf of Mexico is among the highest measured by the U.S. Geological Survey in thirty years.
