Screening guidelines may miss ten percent of colon cancers Posted: 22 Oct 2013 03:31 PM PDT For people with a family history of adenomas (colon polyps that lead to colon cancer), up to 10 percent of colorectal cancers could be missed when current national screening guidelines are followed.

Baby's innate number sense predicts future math skill Posted: 22 Oct 2013 02:08 PM PDT A new study suggests that the strength of an infant's innate sense of numerical quantities can be predictive of that child's mathematical abilities three years later.

Researchers propose social network modeling to fight hospital infections Posted: 22 Oct 2013 02:08 PM PDT Researchers are helping to prevent costly and deadly infections acquired by hospitalized patients by using computer models that simulate interactions between patients and health care workers to determine if these interactions are a source for spreading multi-drug resistant organisms.

New artificial protein mimics part of HIV outer coat Posted: 22 Oct 2013 02:06 PM PDT A team of scientists has created an artificial protein coupled with a sugar molecule that mimics a key site on the outer coat of HIV where antibodies can bind to neutralize a wide variety of HIV strains.

Brief risk-reduction counseling at HIV testing does not result in reduction of STIs Posted: 22 Oct 2013 02:06 PM PDT Brief risk-reduction counseling at the time of a rapid human immunodeficiency virus (HIV) test was not effective for reducing new sexually transmitted infections (STIs) during the subsequent 6 months among persons at risk for HIV, according to a study.

Flu vaccine associated with lower risk of cardiovascular events Posted: 22 Oct 2013 02:06 PM PDT Receiving an influenza vaccination was associated with a lower risk of major adverse cardiovascular events such as heart failure or hospitalization for heart attack, with the greatest treatment effect seen among patients with recent acute coronary syndrome.

Theatre offers promise for youth with autism Posted: 22 Oct 2013 11:37 AM PDT A novel autism intervention program using theatre to teach reciprocal communication skills is improving social deficits in adolescents with the disorder that now affects an estimated one in 88 children.

Heavy air pollution in Canadian area with cancer spikes Posted: 22 Oct 2013 10:21 AM PDT Levels of contaminants higher than in some of the world's most polluted cities have been found downwind of Canada's largest oil, gas and tar sands processing zone, in a rural area where men suffer elevated rates of cancers linked to such chemicals.

Study points to possible treatment for brain disorders Posted: 22 Oct 2013 10:20 AM PDT Scientists are working to determine how neurons are generated, which is vital to providing treatment for neurological disorders like Tuberous Sclerosis Complex.

Hydrogel implant enables light-based communication with cells inside body Posted: 22 Oct 2013 08:36 AM PDT As researchers develop novel therapies based on inducing specific cells to do specific things, getting the right message to the right group of cells at the right time remains a major challenge. Now researchers have developed a way to deliver a light signal to specific cells deep within the body.

'A permanent talent underclass': 'Excellence gap' among American students charted Posted: 22 Oct 2013 08:35 AM PDT A new report finds that high-performing American students are disproportionately white and well-off.

Study of decline of malaria in the US could affect approach to malaria epidemic abroad Posted: 22 Oct 2013 07:22 AM PDT A study of the eradication of the mosquito-borne disease in the US has implications for the approach to malaria abroad, according to scientists.

Light as medicine? Researchers explain how Posted: 22 Oct 2013 07:22 AM PDT Scientists have known for years that certain wavelengths of light in certain doses can heal, but they are only now uncovering exactly how it works.

Coffee consumption reduces risk of liver cancer, analysis suggests Posted: 22 Oct 2013 07:22 AM PDT Coffee consumption reduces risk of hepatocellular carcinoma, the most common type of liver cancer, by about 40 percent, according to an up-to-date meta-analysis. Further, some data indicate that three cups of coffee per day reduce liver cancer risk by more than 50 percent.

Spatial, written language skills predict math competence Posted: 22 Oct 2013 06:18 AM PDT New longitudinal research from Finland has found that children's early spatial skills and knowledge of written letters, rather than oral language skills, predict competence in math. The study included over 1,800 children and has implications for the STEM fields and workforces.

Genome of aggressive lymphoma sequenced Posted: 22 Oct 2013 06:16 AM PDT Mantle cell lymphoma is a very aggressive and difficult-to-treat cancer originated in blood cells and lymph nodes. To identify the molecular alterations responsible for this tumor, and facilitate the development of new treatments, a team of scientists has sequenced the genomes of over 30 of lymphomas. The result of this work presents the first comprehensive genomic analysis of this disease.

Moderate to vigorous exercise boosts teens' academic performance Posted: 21 Oct 2013 06:17 PM PDT Regular moderate to vigorous exercise improves teens' academic performance, and particularly seems to help girls do better in science, indicates research.

Long-term obesity associated with poorer pancreatic cancer survival Posted: 21 Oct 2013 06:14 PM PDT New results from a study show that patients with a body mass index (BMI) in the obese range live on average two to three months less after a pancreatic cancer diagnosis, compared with healthy weight patients, even after adjusting for factors that are known to predict survival for patients with this disease, such as age and disease stage.

Growing up poor, stressed impacts brain function as adult Posted: 21 Oct 2013 06:14 PM PDT Poverty, coupled with stress, has long-lasting effects on brain function, according to a new study. Researchers found that test subjects who had lower family incomes at age 9 exhibited, as adults, greater activity in the amygdala, an area in the brain known for its role in fear and other negative emotions. These individuals showed less activity in areas of the prefrontal cortex, an area in the brain thought to regulate negative emotion.

Single mutation gives virus new target Posted: 21 Oct 2013 01:26 PM PDT A mutation as minute as swapping just one amino acid can completely change the target that a virus will bind to on a victim cell -- potentially shifting what kind of cell and eventually what kind of organism a virus could infect.

Shorter sleep duration, poorer sleep quality linked to Alzheimer’s disease Posted: 21 Oct 2013 01:25 PM PDT New study finds that shorter sleep duration and poorer sleep quality are associated with a greater ²-Amyloid burden, a biomarker for Alzheimer's disease

Bottle feeding associated with increased risk of infant stomach obstruction Posted: 21 Oct 2013 01:25 PM PDT Bottle feeding appears to increase the risk infants will develop hypertrophic pyloric stenosis (HPS), a form of stomach obstruction, and that risk seems to be magnified when mothers are older and have had more than one child.
