This study examined whether a traditional low-impact mind–body exercise, Tai Chi, affects health-related quality-of-life (HRQOL) and headache impact in an adult population suffering from tension-type headaches.
According to the National Headache Foundation, more than 45 million Americans suffer from chronic headaches, with losses of $50 billion a year to absenteeism and medical expenses and an excess of $4 billion spent on over-the-counter medications.
Tension-type headaches (TTH), which represent approximately 78% of all headaches, occur either in single episodes or chronically, and are often the result of temporary stress, anxiety, fatigue or anger.

The next 11-year cycle of solar storms will most likely start next March and peak in late 2011 or mid-2012—up to a year later than expected—according to a forecast issued by the NOAA Space Environment Center in coordination with an international panel of solar experts. The NOAA Space Environment Center led the prediction panel and issued the forecast at its annual Space Weather Workshop in Boulder, Colo. NASA sponsored the panel.

A study in Nature suggested that terrestrial plants may be a global source of the potent greenhouse gas methane, making plants substantial contributors to the annual global methane budget.
This controversial finding and the resulting commotion triggered a consortium (scientists from Plant Research International, IsoLife and Plant Dynamics in Wageningen, Utrecht University, and the Radboud University in Nijmegen) of Dutch scientists to re-examine this in an independent study. Reporting in New Phytologist, Tom Dueck and colleagues present their results and conclude that methane emissions from plants are negligible and do not contribute to global climate change.

Depression may be an early symptom of Parkinson's disease, according to research that will be presented at the American Academy of Neurology's 59th Annual Meeting in Boston, April 28 – May 5, 2007.
The study looked at whether people who are taking antidepressant medications are more likely to develop Parkinson's disease than people who are not taking the medications. It found that, in the year before their Parkinson's disease was diagnosed, people who were taking antidepressants were nearly twice as likely to develop Parkinson's disease as those who were not taking antidepressants.

Brains are able to adjust automatically to the demands of distinguishing between small differences in smell, new research at the University of Chicago shows.
The research, which was conducted on rats, suggests that the human brain may be more adept at distinguishing smells than previously thought. The work comes from studies in the laboratory of Leslie Kay, Assistant Professor in Psychology at the University, who is looking at the ways animals perceive sensory stimuli by focusing on the neural basis of olfactory perception and how context and experience influence it.

Vitamin C is possibly the most important small molecule whose biosynthetic pathway remained a mystery. That is until now.
A group of Dartmouth and UCLA researchers, who normally work on genes involved in aging and cancer in animals, discovered the last piece of the puzzle, they report in a study published in the Journal of Biological Chemistry.

Many studies in coaching literature have found that male athletes tend to prefer a male coach. Newly released research from the University of Alberta has indicated that male athletes actually prefer a female team physician to attend to their medical issues, including those related to sexual health.

With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources.
An article detailing the colorimetric screening technology and its success detecting mercury will be published online April 27 by Angewandte Chemie, the prestigious European journal of applied chemistry.

Arthritis cases on the rise, finds comparative national study, underscoring the need for cost-effective care and disability-reduction efforts
"Arthritis and other rheumatic conditions exact a large and growing economic toll on the nation as a result of the increase in numbers of persons affected, rather than an increase in mean expenditures and earnings losses," attests Charles G. Helmick, M.D., at the National Center for Chronic Disease Prevention and Health Promotion of the Centers for Disease Control and Prevention. He bases his conclusion on a nationwide assessment of medical expenditures and earnings losses associated with arthritis in 2003, compared with figures six years before.

A unique pattern of gene expression observed in rats may be linked to a conditioned desire for food and excessive food intake, an article published today in BMC Biology suggests.

An international has developed a prototype of the first fully integrated prosthetic arm that can be controlled naturally and provide sensory feedback, and allows for eight degrees of Freedom -- a level of control far beyond the current state of the art for prosthetic limbs.

Jesse Sullivan, a former high-power lineman, lost both arms in 2001 after being shocked on the job. Here, he demonstrates the capabilities of the Proto 1 prosthetic arm system during clinical tests at the Rehabilitation Institute of Chicago.

Over time, more women are developing multiple sclerosis (MS) than men, according to research that will be presented at the American Academy of Neurology’s 59th Annual Meeting in Boston, April 28 – May 5, 2007.
In 1940, the ratio of women to men with MS in the United States was approximately two to one. By 2000, that ratio had grown to approximately four to one.
