Unhealthy eating can make a bad mood worse Posted: 15 Mar 2013 05:27 PM PDT Taking part in unhealthy eating behaviors may cause women who are concerned about their diet and self-image to experience a worsening of their moods, according to researchers.

Drug-resistant MRSA bacteria: Here to stay in both hospital and community Posted: 15 Mar 2013 05:27 PM PDT The drug-resistant bac­te­ria known as MRSA, once con­fined to hos­pi­tals but now wide­spread in com­mu­ni­ties, will likely con­tinue to exist in both set­tings as sep­a­rate strains, accord­ing to a new study.

Depression in kids linked to cardiac risks in teens Posted: 15 Mar 2013 05:26 PM PDT Teens who were depressed as children are far more likely than their peers to be obese, smoke cigarettes and lead sedentary lives, even if they no longer suffer from depression. The research suggests that depression, even in children, can increase the risk of heart problems later in life.

Discovery could yield treatment for cocaine addicts Posted: 15 Mar 2013 12:12 PM PDT Scientists have discovered a molecular process in the brain triggered by cocaine use that could provide a target for treatments to prevent or reverse addiction to the drug.

Dating in middle school leads to higher dropout, drug-use rates, study suggests Posted: 15 Mar 2013 12:10 PM PDT Students who date in middle school have significantly worse study skills, are four times more likely to drop out of school and report twice as much alcohol, tobacco and marijuana use than their single classmates, according to new research.

We are still at risk of the plague, new study says Posted: 15 Mar 2013 12:09 PM PDT Today archaeologists unearthed a 'Black Death' grave in London, containing more than a dozen skeletons of people suspected to have died from the plague. The victims are thought to have died during the 14th century and archaeologists anticipate finding many more as they excavate the site. The Plague is by definition a re-emerging infectious disease which affects the lungs and is highly contagious, leading to mass outbreaks across populations.

Improved detection of frontotemporal degeneration may aid clinical trial efforts Posted: 15 Mar 2013 12:08 PM PDT A series of studies demonstrate improved detection of the second most common form of dementia, providing diagnostic specificity that clears the way for refined clinical trials testing targeted treatments.

Tau transmission model opens doors for new Alzheimer's, Parkinson's therapies Posted: 15 Mar 2013 12:08 PM PDT Injecting synthetic tau fibrils into animal models induces Alzheimer's-like tau tangles and imitates the spread of tau pathology, according to new research.

For smokers, low levels of vitamin D may lead to cancer Posted: 15 Mar 2013 12:08 PM PDT New research shows that decreased levels of vitamin D may predispose smokers to developing tobacco-related cancer. This study illustrates that simple vitamin D blood tests and supplements have the potential to improve smokers' health.

No clear evidence that decline in hormone replacement therapy use linked to fall in breast cancer Posted: 15 Mar 2013 04:47 AM PDT There is no clear evidence that the decline in the use of hormone replacement therapy is linked to a reported fall in the numbers of new cases of breast cancer, as has been claimed, suggests a new study.

New cells in the urethra discovered which may detect hazardous substances Posted: 15 Mar 2013 04:47 AM PDT A recent study has revealed the presence of a previously unknown cell in the urethra of mice. These chemosensory cholinergic brush cells are in close contact to sensory neurons that express cholinergic receptors.

Alcohol, fibromyalgia, and quality of life Posted: 15 Mar 2013 04:46 AM PDT Low and moderate drinkers of alcohol reported lower severity of symptoms of fibromyalgia than teetotallers, finds a study. Too much alcohol reversed this effect. The chronic pain of fibromyalgia is thought to affect one in 20 people worldwide but there is no known cause or cure. It often goes hand in hand with fatigue and sleep problems, headaches, depression and irritable bowel and bladder problems. Treatment is based around pain management and lifestyle changes.

Know thyself: How mindfulness can improve self-knowledge Posted: 14 Mar 2013 03:02 PM PDT Mindfulness -- paying attention to one's current experience in a non-judgmental way -- might help us to learn more about our own personalities, according to a new article.

Immune finding aids quest for vaccines to beat tropical infections Posted: 14 Mar 2013 03:01 PM PDT Scientists are a step closer to developing vaccines for a range of diseases that affect 200 million people, mainly in tropical Southeast Asia, Africa and Central America.

Coffee, green tea, may help lower stroke risk Posted: 14 Mar 2013 03:01 PM PDT Green tea and coffee may help lower your risks of having a stroke, especially when both are a regular part of your diet. People who drank either green tea or coffee daily had about approximately 20~30 percent lower risk for one type of stroke, compared to those who seldom drank them.

How vitamin E can help prevent cancer Posted: 14 Mar 2013 02:56 PM PDT Researchers have identified an elusive anti-cancer property of vitamin E that has long been presumed to exist, but difficult to find.
