Scientists refute Greenpeace claim that genetically modified corn caused new insect pest Posted: 07 Jan 2012 12:19 PM PST Researchers refute claims by Greenpeace Germany that the western bean cutworm is "a new plant pest" that was "caused by genetically engineered corn." The Greenpeace Germany report offers a "surprisingly simplistic conclusion" regarding the spread of western bean cutworm over the last decade, according to researchers.

Newly formed plants could lead to improved crop fertility Posted: 07 Jan 2012 12:18 PM PST A new study shows genomes of a recently formed plant species to be highly unstable, a phenomenon that may have far-reaching evolutionary consequences.

Scientists characterize protein essential to survival of malaria parasite Posted: 07 Jan 2012 12:18 PM PST A biology lab has successfully cracked the structure of an enzyme made by Plasmodium falciparum, the parasitical protozoan that causes the most lethal form of malaria. Plasmodium cannot live without the enzyme, which is uses to make cell membrane. Because people don't make this enzyme, it is an ideal target for an anti-malarial drug. Such a drug might kill Plasmodium but have minimal side effects for people.

New primate species discovered on Madagascar Posted: 07 Jan 2012 12:12 PM PST Biologists have discovered a new primate species in the Sahafina Forest in eastern Madagascar, a forest that has not been studied before. The name of the new species is Gerp's mouse lemur (Microcebus gerpi).

New technology tightens cyber security Posted: 06 Jan 2012 01:49 PM PST A revolutionary new technology helps with cyber security.

New hope for diseases of protein folding such as Alzheimer’s, Parkinson’s diseases, ALS, cancer and diabetes Posted: 06 Jan 2012 10:59 AM PST Two related studies offer new strategies for tackling the challenges of preventing and treating diseases of protein folding, such as Alzheimer's, Parkinson's and Huntington's diseases, ALS, cystic fibrosis, cancer and type 2 diabetes. The research identifies new genes and pathways that prevent protein misfolding and toxic aggregation, keeping cells healthy, and also identifies small molecules with therapeutic potential that restore health to damaged cells, providing new targets for drug development.

Mars rover to spend winter at 'Greeley Haven' Posted: 06 Jan 2012 10:03 AM PST NASA's Mars Exploration Rover Opportunity will spend the next few months during the coldest part of Martian winter at Greeley Haven, an outcrop of rock on Mars recently named informally to honor Ronald Greeley, a professor of planetary geology, who died Oct. 27, 2011.

3-D view of 1-D nanostructures Posted: 06 Jan 2012 08:06 AM PST Semiconductor gallium nitride nanowires show great promise in the next generation of nano- and optoelectronic systems. Recently, researchers have found new piezoelectric properties of the nanowires that could make them more useful in self-powered nanodevices.

Platform safety on the radar for researchers Posted: 06 Jan 2012 08:05 AM PST Systems used to detect aircraft and ships could soon be fitted in train stations to quickly identify objects – or even people – that have fallen on the tracks, preventing serious accidents and reducing delays that are frequently caused by these mishaps.

Gunshot, Stabbing Victims Are Recovering without Exploratory Surgery Posted: 06 Jan 2012 07:59 AM PST Although more patients with abdominal gunshot and stab wounds can successfully forego emergency "exploratory" surgery and its potential complications, new research suggests that choosing the wrong patients for this "watchful waiting" approach substantially increases their risk of death from these injuries.

Cell-CT: A new dimension in breast cancer research Posted: 05 Jan 2012 02:58 PM PST Medical researchers have examined normal, benign and malignant cells, using the only research Cell-CT apparatus -- a specialized instrument capable of imaging cells in vivid 3-D with true isotropic resolution. The technology permits the examination of subtle cellular details inaccessible by more conventional forms of microscopy that are inherently 2-D.

Proton therapy effective prostate cancer treatment, study suggests Posted: 05 Jan 2012 02:42 PM PST Proton therapy, a type of external beam radiation therapy, is a safe and effective treatment for prostate cancer, according to two new studies.

Radical liver surgery saves life of young mom, California first Posted: 05 Jan 2012 02:42 PM PST Researchers have successfully performed the west coast's first ex-vivo liver resection, a radical procedure to completely remove and reconstruct a diseased liver and re-implant it without any tumors.

New protein that plays part in arthritis discovered Posted: 05 Jan 2012 02:42 PM PST A new study has shed new light on how proteins interact, or bind, with one another in tissues. Biologists found that a protein called collagen XI interacts with specific proteins in the part of the tissue that provides structural support to the cell.

Ten gynecologic cancer symptoms women shouldn’t ignore Posted: 05 Jan 2012 01:17 PM PST Pelvic pain and abnormal bleeding aren't the only signs of gynecologic cancer. Researchers share other symptoms that often are overlooked.

Comics and jokes are serious teaching tools for linguists Posted: 05 Jan 2012 01:17 PM PST A professor discovers the key to helping students understand complex linguistic principles is through the funny bone.

Statin costs 400 percent higher in US compared to UK, study finds Posted: 05 Jan 2012 11:58 AM PST In the United States, the cost paid for statins in people under the age of 65 who have private insurance is approximately 400 percent higher than comparable costs paid by the government in the United Kingdom. These findings are the first results of a comprehensive comparison of prescription drug costs between the US and UK.

Whiff of 'love hormone' helps monkeys show a little kindness Posted: 05 Jan 2012 11:58 AM PST Oxytocin, the "love hormone" that builds mother-baby bonds and may help us feel more connected toward one another, can also make surly monkeys treat each other a little more kindly.

Low vitamin D levels linked to depression, psychiatrists report Posted: 05 Jan 2012 10:16 AM PST Low levels of vitamin D have been linked to depression, according to psychiatrists.
