Testosterone makes us less cooperative and more egocentric Posted: 31 Jan 2012 06:02 PM PST Testosterone makes us overvalue our own opinions at the expense of cooperation, new research has found. Higher levels of testosterone were associated with individuals behaving egocentrically.

Honey could be effective at treating and preventing wound infections Posted: 31 Jan 2012 05:59 PM PST Manuka honey could help clear chronic wound infections and even prevent them from developing in the first place, according to a new study. The findings provide further evidence for the clinical use of manuka honey to treat bacterial infections in the face of growing antibiotic resistance.

Pairing masks and hand washing could drastically slow spread of a pandemic flu Posted: 31 Jan 2012 02:57 PM PST Masks and hand hygiene could cut the spread of flu-like symptoms up to 75 percent, a new study found.

Gene mutation in autism found to cause hyperconnectivity in brain's hearing center Posted: 31 Jan 2012 02:56 PM PST New research might help explain how a gene mutation found in some autistic individuals leads to difficulties in processing auditory cues and paying spatial attention to sound.

New genetic subtype of lung cancer defined Posted: 31 Jan 2012 09:25 AM PST Investigators have defined the role of a recently identified gene abnormality – rearrangements in the ROS1 gene – in a deadly form of lung cancer. ROS1-rearranged tumors represent one to two percent of non-small-cell lung cancers, the leading cause of cancer death in the US. The researchers also show that ROS1-driven tumors can be treated with crizotinib and describe the remarkable response of one patient to crizotinib treatment.

Exposure to common environmental bacteria may be source of some allergic inflammation Posted: 31 Jan 2012 09:18 AM PST Could some cases of asthma actually be caused by an allergic reaction to a common environmental bacteria? New research findings suggests that this idea may not be as far-fetched as it seems.

Short-term memory is based on synchronized brain oscillations Posted: 31 Jan 2012 09:14 AM PST Holding information within one's memory for a short while is a seemingly simple and everyday task. We use our short-term memory when remembering a new telephone number if there is nothing to write at hand, or to find the beautiful dress inside the store that we were just admiring in the shopping window. Yet, despite the apparent simplicity of these actions, short-term memory is a complex cognitive act that entails the participation of multiple brain regions. However, whether and how different brain regions cooperate during memory has remained elusive. Researchers in Germany have now come closer to answering this question. They discovered that oscillations between different brain regions are crucial in visually remembering things over a short period of time.

Norovirus is the leading cause of infection outbreaks in U.S. hospitals Posted: 31 Jan 2012 09:14 AM PST Norovirus, a pathogen that often causes food poisoning and gastroenteritis, was responsible for 18.2 percent of all infection outbreaks and 65 percent of ward closures in U.S. hospitals during a two-year period.

Protein study gives fresh impetus in fight against superbugs Posted: 31 Jan 2012 07:25 AM PST Scientists have shed new light on the way superbugs such as MRSA are able to become resistant to treatment with antibiotics.

Surprise finding redraws 'map' of blood cell production Posted: 31 Jan 2012 06:31 AM PST A study of the cells that respond to crises in the blood system has yielded a few surprises, redrawing the 'map' of how blood cells are made in the body. The finding could have wide-ranging implications for understanding blood diseases such as myeloproliferative disorders as well as used to develop new ways of controlling how blood and clotting cells are produced.

Stimulation of brain hormone action may improve pneumonia survival Posted: 31 Jan 2012 06:30 AM PST An international research team may have found a way to block a second wave of death that can result from pneumonia treatment.

Are diet soft drinks bad for you? Posted: 31 Jan 2012 06:27 AM PST A new study finds a potential link between daily consumption of diet soft drinks and the risk of vascular events.

Researchers identify cell-permeable peptide that inhibits hepatitis C Posted: 31 Jan 2012 06:24 AM PST Researchers have identified a cell-permeable peptide that inhibits a hepatitis C virus protein and blocks viral replication, which can lead to liver cancer and cirrhosis.

Skin cells turned into neural precusors, bypassing stem-cell stage Posted: 30 Jan 2012 02:19 PM PST Mouse skin cells can be converted directly into cells that become the three main parts of the nervous system, according to researchers. The finding is an extension of a previous study by the same group showing that mouse and human skin cells can be directly converted into functional neurons.

Mom's love good for child's brain Posted: 30 Jan 2012 02:01 PM PST School-age children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress. The new research, by child psychiatrists and neuroscientists, is the first to show that changes in this critical region of children's brain anatomy are linked to a mother's nurturing.
