Researchers identify brain network with mapping technique Posted: 18 Jul 2014 06:50 PM PDT A new image-based strategy has been used to identify and measure placebo effects in randomized clinical trials for brain disorders. The researchers used a network mapping technique to identify specific brain circuits underlying the response to sham surgery in Parkinson's disease patients.

New trigger for ovulation could make IVF safer Posted: 18 Jul 2014 06:49 PM PDT A new and potentially safer method to stimulate ovulation in women undergoing IVF treatment has been developed by researchers. Twelve babies have been born after their mothers were given an injection of the natural hormone kisspeptin to make their eggs mature. Doctors normally administer another hormone, hCG, for this purpose, but in some women, there is a risk that this can overstimulate the ovaries, with potentially life-threatening consequences.

Antipsychotic drugs linked to slight decrease in brain volume Posted: 18 Jul 2014 02:20 PM PDT A new study has confirmed a link between antipsychotic medication and a slight, but measureable, decrease in brain volume in patients with schizophrenia. For the first time, researchers have been able to examine whether this decrease is harmful for patients' cognitive function and symptoms, and noted that over a nine year follow-up, this decrease did not appear to have any effect.

Consuming probiotics for a month helps diminish fat accumulation in the liver, according to a new study Posted: 18 Jul 2014 06:56 AM PDT Scientists have demonstrated through an experiment on obese rats that the consumption of probiotics for thirty days helps diminish the accumulation of fat in the liver. This new findingis a step forward on the fight against Non-Alcolohic Fatty Liver Disease (NAFLD), which is closely related to obesity and diabetes.

Help wanted: School principals who love change Posted: 17 Jul 2014 11:20 AM PDT Teacher evaluation is key to President Obama's Race to the Top education reform initiative, which in turn places demands on principals' expertise and time. After analyzing six school districts across the US with innovative support and training for principals, researchers have developed recommendations for school districts including focusing principal training on coaching teachers, redesigning principal job descriptions to focus on teachers and student outcomes, and developing partnerships with universities to recruit and train future principals.

Exploiting gastric vulnerability Posted: 17 Jul 2014 11:19 AM PDT Helicobacter pylori infection promotes stomach ulcers and cancer. How H. pylori initially interacts with and irritates gastric tissue is not well understood. A new article now describes that H. pylori rapidly identifies and colonizes sites of minor injuries in the stomach, almost immediately interferes with healing at those injury sites, and so promotes sustained gastric damage.
