Poor mental health linked to reduced life expectancy Posted: 31 Jul 2012 05:12 PM PDT People with mental health problems have a lower life expectancy, according to a large-scale population based study. The findings may prompt further research into the way doctors treat patients with even mild psychological problems.

When we forget to remember: Failures in prospective memory range from annoying to lethal Posted: 31 Jul 2012 12:17 PM PDT Why would highly skilled professionals forget to perform a simple task they have executed without difficulty thousands of times before? These kinds of oversights occur in professions as diverse as aviation and computer programming, but research reveals that these lapses may not reflect carelessness or lack of skill but failures of prospective memory.

Eyes and attention of men and women meander in distinctly different ways Posted: 31 Jul 2012 12:17 PM PDT Researchers show that the eyes and attention of men and women meander in distinctly different ways. Men park their eyes on the speaker's mouth. Women shift their focus between the speakers eyes and body.

Concussions and head impacts may accelerate brain aging Posted: 31 Jul 2012 12:17 PM PDT Concussions and even lesser head impacts may speed up the brain's natural aging process by causing signaling pathways in the brain to break down more quickly than they would in someone who has never suffered a brain injury or concussion.

Immune responses can be generated locally within human melanoma skin metastases Posted: 31 Jul 2012 10:48 AM PDT In many types of cancer, activated immune cells infiltrate the tumor and influence clinical outcome. It is not always clear where these cells are activated, but new results indicate that in a subset of patients with metastatic melanoma, they can be activated in the tumor micro-environment.

Protein-based coating could help rehabilitate long-term brain function Posted: 31 Jul 2012 09:35 AM PDT Scientists have developed a bioactive coating which not only "camouflages" electrodes in the brain tissue but also suppresses the brain's immune response.

New anesthesia drugs developed to be 'fast, clean, and soft' Posted: 31 Jul 2012 09:32 AM PDT Researchers are using sophisticated and powerful new tools to develop and evaluate new anesthetic agents with important advantages over current drugs, according to a several new articles.

IL-10 from donor skin cells helps the body incorporate skin grafts Posted: 31 Jul 2012 08:14 AM PDT Scientists have found that the anti-inflammatory molecule, IL-10, may improve success rates of skin autografts (skin moved from one site of the body to another). This information provides a valuable drug target that may benefit burn and accident victims.

Dementia: Autoantibodies damage blood vessels in the brain Posted: 31 Jul 2012 08:14 AM PDT The presence of specific autoantibodies of the immune system is associated with blood vessel damage in the brain. New results suggest that autoimmune mechanisms play a significant role in the pathogenesis and progression of Alzheimer's and vascular dementia.

Olympics for the rest of us: How ping-pong can help your brain Posted: 31 Jul 2012 08:13 AM PDT The physical benefits of the Olympic sports are pretty obvious: strength, endurance and agility, to name a few. But did you know they also can help the brain? New research shows that any exercise that gets the heart pumping may reduce the risk of dementia and mild cognitive impairment -- and slow those conditions if they start. Aerobic exercise also can boost your mood.

Opioid receptors as a drug target for stopping obesity Posted: 31 Jul 2012 07:30 AM PDT Imagine eating all of the sugar and fat that you want without gaining a pound. Thanks to new research the day may come when this is not too far from reality.

Allergies? Your sneeze is a biological response to the nose's 'blue screen of death' Posted: 31 Jul 2012 07:30 AM PDT Who would have thought that our noses and Microsoft Windows' infamous blue screen of death could have something in common? New research suggests that sneezing is the body's natural reboot and that patients with disorders of the nose such as sinusitis can't reboot, explaining why they sneeze more often than others.

'Flightless' molecule may prevent cancer from spreading from one tissue to another Posted: 31 Jul 2012 07:30 AM PDT Thanks to the "flightless" molecule, the spread of cancer from one tissue to another may one day be grounded. Laboratory experiments show that "flightless" (named after its effects on fruit flies) increases the "stickiness" that causes cells, including cancer cells, to attach to underlying tissue, which in turn, slows their movement throughout the body.

Ecosystems reveal radiation secrets: Transfer of radioactive compounds is not straightforward Posted: 31 Jul 2012 07:30 AM PDT A new study casts doubt over the validity of models used to assess the impact of radiation on human health.

A good network is important for brain activity Posted: 31 Jul 2012 07:29 AM PDT Speech, sensory perception, thought formation, decision-making processes and movement are complex tasks that the brain only masters when individual nerve cells (neurons) are well connected. Neuroscientists have now discovered a molecular switch that regulates this networking of nerve cells.

Domestic violence: New research focuses on treatment for perpetrator, not victim Posted: 31 Jul 2012 06:47 AM PDT A new experiment takes an unconventional look at the treatment for domestic violence, otherwise known as intimate partner violence (IPV), by focusing on changing the perpetrators' psychological abuse during arguments rather than addressing his sexist beliefs.

Anxiety and depression increase risk of sick leave Posted: 31 Jul 2012 06:46 AM PDT Long-term sick leave is a burden for individuals and society at large, yet very little is known about the underlying reasons for it. Researchers have identified anxiety as a more important risk factor than previously thought.

Adolescents in substance abuse treatment report using someone else's medical marijuana Posted: 31 Jul 2012 06:46 AM PDT Diverted medical marijuana use among adolescents receiving treatment for substance abuse is very common, according to new research. Study participants from two adolescent substance abuse treatment programs in the Denver metropolitan area were asked questions about their medical marijuana use. 121 of 164 adolescents (73.8%) reported using medical marijuana that had been recommended for someone else, also known as diverted medical marijuana, a median of 50 times.

Micro-copier for genome analysis Posted: 31 Jul 2012 06:46 AM PDT A new method holds promise to advance personalized medicine. Scientists can now copy 100,000 different DNA sequences simultaneously in a so called picowell array the size of a one cent coin.

Defining the architecture of rhomboid enzymes Posted: 31 Jul 2012 06:41 AM PDT Scientists have decoded for the first time the "stability blueprint" of an enzyme that resides in a cell's membrane, mapping which parts of the enzyme are important for its shape and function. These studies could eventually lead to the development of drugs to treat malaria and other parasitic diseases.

Most with celiac disease unaware of it; others go gluten-free without diagnosis Posted: 31 Jul 2012 06:41 AM PDT Roughly 1.8 million Americans have celiac disease, but around 1.4 million of them are unaware that they have it, a new analysis of the condition's prevalence has found.
