Pesticides increase risk for Parkinson's disease: Certain people may be more susceptible Posted: 03 Feb 2014 01:34 PM PST Previous studies have shown the certain pesticides can increase the risk for developing Parkinson's disease. Now, researchers have now found that the strength of that risk depends on an individual's genetic makeup, which in the most pesticide-exposed populations could increase the chances of developing the debilitating disease by two- to six-fold.

Perceived personal control reduces mortality risk at low, not high, education levels Posted: 03 Feb 2014 10:36 AM PST Personality researchers find having a sense of control over one's life can reduce mortality rates in people who have little education, but a sense of control does not influence mortality rates in people with higher levels of education.

Mood-stabilizing drug could treat inherited liver disease, study shows Posted: 03 Feb 2014 10:36 AM PST Opening up a can of worms is a good way to start hunting for new drugs. In a study published, researchers demonstrate how they used a primitive worm model to show that a drug typically used to treat agitation in schizophrenia and dementia has potential as a treatment for ±-1 antitrypsin deficiency.

Biostatistics approach to genetics yields new clues to roots of autism Posted: 03 Feb 2014 10:35 AM PST Researchers have developed a statistical method for genetic screens that improves the classic genome-wide association screen, and, applying to autism, have uncovered genes related to the disorder that had not been suggested in previous analyses. The scientists offer evidence that beginning treatment in infants at the first symptoms could change the course of the disease, possibly preventing the permanent "pruning" of neurons, which occurs during the first two years of life, from cementing autistic symptoms in place.

Researchers have found that personalized cancer screening messages over the phone can better help promote preventive cancer measures.

Genetic function of tumor suppressor gene discovered; could offer new avenue to cancer therapies Posted: 03 Feb 2014 09:28 AM PST Researchers have discovered a genetic function that helps one of the most important "tumor suppressor" genes to do its job and prevent cancer. Finding ways to maintain or increase the effectiveness of this gene could offer an important new avenue for human cancer therapies.

New method to restore skull after brain surgery appears to reduce complication rates Posted: 03 Feb 2014 09:28 AM PST Surgeons report they have devised a better, safer method to replace bone removed from the skull after lifesaving brain surgery. The new technique, they say, appears to result in fewer complications than standard restoration, which has changed little since its development in the 1890s.

Earlier depression treatment prevents heart attacks, strokes, study shows Posted: 03 Feb 2014 09:28 AM PST New research is the first to find that treatment of depression before any apparent signs of cardiovascular disease can decrease the risk of future heart attacks and strokes by almost half.

Murderers who killed during robberies more likely to return to crime when paroled Posted: 03 Feb 2014 08:35 AM PST Murderers who committed homicide during robberies are more likely to commit crimes again when they are paroled, compared to murderers who committed homicide under other circumstances, according to research.

Written all over your face: Humans express four basic emotions rather than six Posted: 03 Feb 2014 08:35 AM PST Human beings are emotional creatures whose state of mind can usually be observed through their facial expressions. A commonly-held belief posits there are six basic emotions which are universally recognized and easily interpreted through specific facial expressions, regardless of language or culture. These are: happiness, sadness, fear, anger, surprise and disgust. New research suggests that in fact, there are really only four.

Whether you lose or gain weight depends on weekdays Posted: 03 Feb 2014 05:45 AM PST Almost everyone loses weight on weekdays and gains weight on weekends. What separates the slim from the heavy isn't how much more they gain on weekends. It's how much they lose during the weekdays. In this study, researchers look into the impact that the seven-days-a-week human cycle has on weight.

Shy kids not delayed or deficient in language, they just speak less Posted: 03 Feb 2014 05:42 AM PST Previous research has suggested that shy children have difficulties with language. A new longitudinal study of 816 toddlers has found that shy children who are inhibited in their behavior understand what's being said as well as less shy peers, even though they tend to speak less. In other words, these children are merely reluctant to respond rather than delayed or deficient in understanding language.

For young African-Americans, emotional support buffers biological toll of racial discrimination Posted: 03 Feb 2014 05:42 AM PST A new study has found that African-American youth who report experiencing frequent discrimination during adolescence are at risk for developing chronic diseases like heart disease in later years. The study, which looked at 331 rural youth living in Georgia, found that emotional support from parents and peers can protect from the effects of allostatic load -- biological wear and tear due to exposure to repeated stress.

Positive feelings about race, ethnicity tied to stronger development in minority youth Posted: 03 Feb 2014 05:42 AM PST A meta-analyses of 46 studies reviewing ethnic-racial affect has found that the more positively minority youth feel about their ethnicity or race, the fewer symptoms of depression and behavior problems they have.
