New research reveals the catastrophic loss of Cambodia's tropical flooded grasslands. Around half of Cambodia's tropical flooded grasslands have been lost in just 10 years according to new research.

Vitamin D replacement improves muscle efficiency

Posted: 17 Mar 2013 07:14 PM PDT

New research shows for the first time a link between vitamin D levels and muscle efficiency. Vitamin D supplementation may also be effective in improving skeletal muscle function. The findings may explain the physical fatigue commonly experienced by patients with vitamin D deficiency, with broad implications for a large section of society.

When it rains these days, does it pour? Has the weather become stormier as the climate warms?

Posted: 17 Mar 2013 12:48 PM PDT

Scientists have shown that the signature of an increase in storminess could be extracted from precipitation data for the Olympic Peninsula in Washington State. The scientists suspect the same signature lies hidden under naturally stormier weather at other locations as well.

Ocean plankton sponge up nearly twice the carbon currently assumed

Posted: 17 Mar 2013 12:47 PM PDT

Models of carbon dioxide in the world's oceans need to be revised, according to new work. Trillions of plankton near the surface of warm waters are far more carbon-rich than has long been thought, they found.

Highly effective communities of bacteria in the world's deepest oceanic trench

Deep sea trenches act as hot spots for microbial activity, according to new research.

White blood cells found to play key role in controlling red blood cell levels

Posted: 17 Mar 2013 12:47 PM PDT

Researchers have found that macrophages – white blood cells that play a key role in the immune response – also help to both produce and eliminate the body's red blood cells (RBCs). The findings could lead to novel therapies for diseases or conditions in which the red blood cell production is thrown out of balance.

Novel drug delivery system releases drugs in response to compression by the patient's hand

Medical researchers have succeeded in developing a gel material which is capable of releasing drugs in response to pressure applied by the patient.

New drugs may improve quality of life for people with Parkinson's disease

Posted: 14 Mar 2013 02:57 PM PDT

Three new studies present possible positive news for people with Parkinson's disease. The studies report on treatments for blood pressure problems, the wearing-off that can occur when people have taken the main drug for Parkinson's for a long time, and for people early in the disease whose symptoms are not well-controlled by their main drugs.

Two-pronged immune cell approach could lead to a universal shot against the flu

Posted: 14 Mar 2013 02:56 PM PDT

Influenza virus-specific CD8+ T cells or virus-specific non-neutralizing antibodies are each relatively ineffective at conferring protective immunity alone. But, when combined, the virus-specific CD8 T cells and non-neutralizing antibodies cooperatively elicit robust protective immunity.

Smart-bombing cancer, Alzheimer's disease, and more

Posted: 14 Mar 2013 11:42 AM PDT

Scientists are crafting new pharmaceuticals that could dramatically improve a patient's odds when heavy-duty drugs are prescribed. The research is focused on developing drugs with the kind of precision that the military seeks with smart bombs.

Predicting hotspots for future flu outbreaks

Posted: 14 Mar 2013 11:13 AM PDT

A major pandemic could occur if bird flu were to become highly contagious among humans. Scientists are making sure we get a leg up on the threat by developing predictions about where outbreaks are most likely to begin.

College kids who don't drink milk could face serious consequences

Posted: 14 Mar 2013 11:11 AM PDT

College-age kids who don't consume at least three servings of dairy daily are three times more likely to develop metabolic syndrome than those who do, said a new study. "That alarming finding means that three-fourths of the 18- to 25-year-old college applicants surveyed are at risk for metabolic syndrome ," said a professor of food science and human nutrition.

Fungus uses copper detoxification as crafty defense mechanism

Posted: 14 Mar 2013 11:11 AM PDT

A potentially lethal fungal infection appears to gain virulence by being able to anticipate and disarm a hostile immune attack in the lungs, according to a new article.

Outside the box: Brain aneurysm treatment used to stop irregular heart rhythms

Posted: 14 Mar 2013 11:09 AM PDT

For the first time, scientists have used a technique normally employed in treating brain aneurysms to treat severe, life-threatening irregular heart rhythms in two patients.
