First documented case of child cured of HIV Posted: 03 Mar 2013 02:26 PM PST Researchers have described the first documented case of a child being cured of HIV. The case involves a two-year-old child in Mississippi diagnosed with HIV at birth and immediately put on antiretroviral therapy. At 18 months, the child ceased taking antiretrovirals and was lost to follow-up. When brought back into care at 23 months, despite being off treatment for five months, the child was found to have an undetectable viral load. A battery of subsequent highly sensitive tests confirmed the absence of HIV.

Human metabolism in health and disease mapped Posted: 03 Mar 2013 12:50 PM PST Scientists have produced the most comprehensive virtual reconstruction of human metabolism to date. Scientists could use the model, known as Recon 2, to identify causes of and new treatments for diseases like cancer, diabetes and even psychiatric and neurodegenerative disorders.

Getting around the uncertainty principle: Physicists make first direct measurements of polarization states of light Posted: 03 Mar 2013 12:49 PM PST Researchers have applied a recently developed technique to directly measure for the first time the polarization states of light. Their work both overcomes some important challenges of Heisenberg's famous Uncertainty Principle and also is applicable to qubits, the building blocks of quantum information theory.

Adding to the list of disease-causing proteins in brain disorders Posted: 03 Mar 2013 12:49 PM PST Researchers have found new candidate disease proteins for neurodegenerative disorders. They describe mutations in prion-like segments of two RNA-binding proteins are associated with a rare inherited degeneration disorder affecting muscle, brain, motor neurons and bone (called multisystem proteinopathy) and one case of the familial form of amyotrophic lateral sclerosis.

Seven genetic risk factors found to be associated with common eye disorder Posted: 03 Mar 2013 12:49 PM PST Scientists have discovered seven new regions of the human genome -- called loci -- that are associated with increased risk of age-related macular degeneration, a leading cause of blindness.

Scientists discover how to shutdown cancer's powerful master protein Posted: 03 Mar 2013 12:49 PM PST The powerful master regulatory transcription factor called Bcl6 is key to the survival of a majority of aggressive lymphomas, which arise from the B-cells of the immune system. The protein has long been considered too complex to target with a drug since it is also crucial to the healthy functioning of many immune cells in the body, not just B cells gone bad.

Human-made material pushes the bounds of superconductivity Posted: 03 Mar 2013 12:48 PM PST Scientists have artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications.

Two new genes linked to amyotrophic lateral sclerosis (ALS) and related disorders Posted: 03 Mar 2013 12:48 PM PST Scientists have discovered mutations in two genes that lead to the death of nerve cells in amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, and related degenerative diseases.

Cancer vaccines self-sabotage, channel immune attack to injection site Posted: 03 Mar 2013 12:48 PM PST Cancer vaccines that attempt to stimulate an immune system assault fail because the killer T cells aimed at tumors instead find the vaccination site a more inviting target, scientists report.

Early warning system provides four-month forecast of malaria epidemics in northwest india Posted: 03 Mar 2013 12:48 PM PST Sea surface temperatures in the tropical South Atlantic Ocean can be used to accurately forecast, by up to four months, malaria epidemics thousands of miles away in northwestern India, theoretical ecologists have found.

Scientists identify 'clean-up' snafu that kills brain cells in Parkinson's disease Posted: 03 Mar 2013 12:48 PM PST Researchers have discovered how the most common genetic mutations in familial Parkinson's disease damage brain cells.

SpaceX's Dragon carrying NASA cargo resupplies space station Posted: 03 Mar 2013 07:22 AM PST The Space Exploration Technologies Corp. (SpaceX) Dragon spacecraft was berthed to the International Space Station at 8:56 a.m. EST Sunday. The delivery flight was the second contracted resupply mission by the company under NASA's Commercial Resupply Services contract.
