Catastrophic loss of Cambodia's tropical flooded grasslands Posted: 17 Mar 2013 07:14 PM PDT 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 Posted: 17 Mar 2013 12:47 PM PDT 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 Posted: 17 Mar 2013 12:47 PM PDT Medical researchers have succeeded in developing a gel material which is capable of releasing drugs in response to pressure applied by the patient.

New study points to the aggressive potential of small kidney tumors, advocates treatment Posted: 16 Mar 2013 04:05 PM PDT Small kidney tumors have an aggressive potential and should be treated, according to a the results of a large multicenter study.

Stem cells transplantation technique has high potential as a novel therapeutic strategy for erectile dysfunction Posted: 15 Mar 2013 04:47 AM PDT Transplantation of mesenchymal stem cells cultivated on the surface of nanofibrous meshes could be a novel therapeutic strategy against post-prostatectomy erectile dysfunction.

Japanese P2 study shows potential of combined vaccine and steroid drug in castration resistant PCa Posted: 15 Mar 2013 04:47 AM PDT Multi-peptide vaccination therapy combined with the low-dose steroid drug dexamethasone shows promise in treating chemotherapy-naive castration resistant prostate cancer patients.

New study on UTIs suggests flagellin is key in stimulating body's natural defenses Posted: 15 Mar 2013 04:47 AM PDT A new study reveals that motile Escherichia coli isolates demonstrated significant activation of NF-ºB signaling suggesting that flagellin plays a key role in up-regulating the host innate defenses against urinary tract infections.

Surgery is superior to radiotherapy in men with localized PCa Posted: 15 Mar 2013 04:47 AM PDT Surgery offers better survival benefit for men with localized prostate cancer, according to a large observational study.

NASA's first laser communication system integrated, ready for launch Posted: 14 Mar 2013 03:03 PM PDT A new NASA-developed, laser-based space communication system will enable higher rates of satellite communications similar in capability to high-speed fiber optic networks on Earth.

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.

No sons linked to lower contraception use in Nepal Posted: 14 Mar 2013 02:57 PM PDT While poverty and under-education continue to dampen contraception use in Nepal, exacerbating the country's efforts to reduce maternal and child mortality rates, researchers say another, more surprising factor may be more intractable: Deeply held cultural preferences for sons over daughters.

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.
