Food fried in olive or sunflower oil is not linked to heart disease, Spanish study finds Posted: 24 Jan 2012 03:41 PM PST Eating food fried in olive or sunflower oil is not linked to heart disease or premature death, a new study finds. The authors stress, however, that their study took place in Spain, a Mediterranean country where olive or sunflower oil is used for frying and their results would probably not be the same in another country where solid and re-used oils were used for frying.

Increased exposure to compound widely used in food packaging associated with reduced immune response to vaccinations for children Posted: 24 Jan 2012 01:23 PM PST Elevated exposures in children to perfluorinated compounds, which are widely used in manufacturing and food packaging, were associated with lower antibody responses to routine childhood immunizations, according to a new study.

Women with certain type of ovarian cancer and BRCA gene mutation have improved survival at 5 years Posted: 24 Jan 2012 01:23 PM PST Among women with invasive epithelial ovarian cancer, patients having a germline (gene change in a reproductive cell that could be passed to offspring) mutation in the BRCA1 or BRCA2 genes was associated with improved five-year overall survival, with BRCA2 carriers having the best prognosis, according to a new study.

High levels of fructose consumption by adolescents may put them at cardiovascular risk, evidence suggests Posted: 24 Jan 2012 11:03 AM PST Evidence of cardiovascular disease and diabetes risk is present in the blood of adolescents who consume a lot of fructose, a scenario that worsens in the face of excess belly fat, researchers report.

Entry point for hepatitis C infection identified Posted: 24 Jan 2012 10:44 AM PST A molecule embedded in the membrane of human liver cells that aids in cholesterol absorption also allows the entry of hepatitis C virus, the first step in hepatitis C infection, according to new research.

It's evolution: Nature of prejudice, aggression different for men and women Posted: 24 Jan 2012 08:30 AM PST Prejudice against people from groups different than their own is linked to aggression for men and fear for women, suggests new research.

How longstanding conflict influences empathy for others Posted: 24 Jan 2012 08:30 AM PST A young researcher had long been drawn to conflict -- not as a participant, but an observer. In 1994, while doing volunteer work in South Africa, he witnessed firsthand the turmoil surrounding the fall of apartheid; during a 2001 trip to visit friends in Sri Lanka, he found himself in the midst of the violent conflict between the Tamil Tigers and the Sri Lankan military. He is now exploring how longstanding conflict influences empathy for others.

Foot and ankle structure differs between sprinters and non-sprinters Posted: 24 Jan 2012 08:21 AM PST The skeletal structure of the foot and ankle differs significantly between human sprinters and non-sprinters, according to researchers. Their findings not only help explain why some people are faster runners than others, but also may be useful in helping people who have difficulty walking, such as older adults and children with cerebral palsy.

Spotting dyslexia before a child starts school Posted: 23 Jan 2012 12:25 PM PST Children at risk for dyslexia show differences in brain activity on MRI scans even before they begin learning to read, finds a new study. Since developmental dyslexia responds to early intervention, diagnosing children at risk before or during kindergarten could head off difficulties and frustration in school, the researchers say.

The price of your soul: How the brain decides whether to 'sell out' Posted: 22 Jan 2012 05:12 PM PST A neuro-imaging study shows that personal values people refuse to disavow, even when offered cash, are processed differently in the brain than those values that are willingly sold. The experiment found that the realm of the sacred -- whether a strong religious belief, national identity or code of ethics -- is a distinct cognitive process, and prompts greater activation of a brain area associated with rules-based, right-or-wrong thought processes, as opposed to regions linked to costs-versus-benefits thought.

Inflammatory mediator promotes colorectal cancer by stifling protective genes Posted: 22 Jan 2012 12:25 PM PST Chronic inflammation combines with DNA methylation, a process that shuts down cancer-fighting genes, to promote development of colorectal cancer, scientists have discovered.
