Gene critical for development of brain motor center found Posted: 20 Jun 2014 01:33 PM PDT A research team describes a gene called Snf2h, which is found in our brain's neural stem cells and functions as a master regulator. When they removed this gene early on in a mouse's development, its cerebellum only grew to one-third the normal size. It also had difficulty walking, balancing and coordinating its movements, something called cerebellar ataxia that is a component of many neurodegenerative diseases.

Wealth and greed: How independent boards, managerial discretion, CEO tenure affect shareholder wealth Posted: 20 Jun 2014 11:39 AM PDT The pursuit of extreme wealth by top managers can lead to lower performance and loss of shareholder value, a new study finds. But, a powerful board or long CEO tenure can moderate the impact.

Effectiveness of PTSD treatments provided by DOD, VA unknown Posted: 20 Jun 2014 11:39 AM PDT The US Department of Defense and US Department of Veterans Affairs should track the outcomes of treatment for post-traumatic stress disorder (PTSD) provided to service members and veterans and develop a coordinated and comprehensive strategy to do so, says a new congressionally mandated report.

Citing 'urgent, acute' mental health issues, especially in Africa, experts petition gov'ts to act Posted: 20 Jun 2014 09:04 AM PDT Calling global mental health problems 'acute and urgent,' leading authorities from 11 countries have published a joint declaration calling for basic mental health care in Africa. Experts call for global mental health objectives to be included among the United Nations' post-2015 Sustainable Development Goals.

Safe water for the people in Tanzania Posted: 20 Jun 2014 07:23 AM PDT Hydraulic engineers and photovoltaics experts have developed a solar filtration system to produce high-quality drinking water from polluted brackish water and tested it successfully in Tanzania. The test results are currently being analyzed. The filter effectively separates undesired substances, bacteria, and viruses.

Emerging HIV epidemics among people who inject drugs in the Middle East and North Africa Posted: 19 Jun 2014 11:22 AM PDT HIV epidemics are emerging among people who inject drugs in several countries in the Middle East and North Africa. Though HIV infection levels were historically very low in the Middle East and North Africa, substantial levels of HIV transmission and emerging HIV epidemics have been documented among people who inject drugs in at least one-third of the countries of this region, according to research findings.

In hairless man, arthritis drug spurs hair growth -- lots Posted: 19 Jun 2014 09:53 AM PDT A man with almost no hair on his body has grown a full head of it after a novel treatment. There is currently no cure or long-term treatment for alopecia universalis, the disease that left the 25-year-old patient bare of hair. This is the first reported case of a successful targeted treatment for the rare, highly visible disease.

Tiny molecule could help diagnose, treat mental disorders Posted: 19 Jun 2014 09:53 AM PDT According to the World Health Organization, such mood disorders as depression affect some 10% of the world's population and are associated with a heavy burden of disease. Now, scientists report that they have 'fingerprinted' a culprit in depression, anxiety and other mood disorders.

Feel-good hormones could cause UV addiction Posted: 19 Jun 2014 09:52 AM PDT Sun lovers eagerly flock to the beach every summer, despite widespread awareness of the risk of skin cancer. A new study reveals that chronic exposure to UV radiation causes the release of feel-good hormones called endorphins, which act through the same pathway as heroin, leading to physical dependence, tolerance, and addiction-like behavior in rodents. The findings could explain why people have an instinctive desire to be in the sun, despite its known health risks.

Humans and monkeys of one mind when it comes to changing it Posted: 19 Jun 2014 09:49 AM PDT Covert changes of mind can be discovered by tracking neural activity when subjects make decisions, researchers have found. Their results, offer new insights into how we make decisions and point to innovative ways to study this process in the future.

Depression linked to higher heart disease death risk in younger women Posted: 18 Jun 2014 01:51 PM PDT Women 55 and younger are twice as likely to suffer a heart attack, die or require artery-opening procedures if they're depressed. Women in this age group are also more likely than men and older women to suffer from depression -- possibly a 'hidden' risk factor that helps explain why more women die after a heart attack.
