More than a decade of research hinting that magnesium supplements might boost your brain power is finally being put to the test in a small clinical trial. The research, led by biopharmaceutical company Magceutics of Hayward, California, began testing the ability of its product Magtein to boost magnesium ion (Mg2+) levels in the brain earlier this month. The trial will track whether the ions can decrease anxiety and improve sleep quality, as well as following changes in the memory and cognitive ability of participants. But critics caution that the trial in just 50 people is too small to draw definitive conclusions.

The most common and aggressive brain tumor grows by turning normal brain cells into stem cells, which can continuously replicate and regrow a tumor with only a handful of cells left behind, new research finds.

Only recently have researchers begun to understand how the teen brain is wired and that some of what appear to be teens' senseless choices may result from biological tendencies that also prime their brains to learn and be flexible.

The brain that revolutionized physics now can be downloaded as an app for $9.99. But it won't help you win at Angry Birds. While Albert Einstein's genius isn't included, an exclusive iPad application launched Tuesday promises to make detailed images of his brain more accessible to scientists than ever before. Teachers, students and anyone who's curious also can get a look.

Microsoft cofounder Paul Allen helped revolutionize the world with personal computers. Now he's betting a half-billion dollars that he can do something even more radical: draw a circuit diagram of human consciousness.

The NFL has pledged $30 million for medical research to the Foundation for the National Institutes of Health... Potential areas of research under the grant include the brain, specifically chronic traumatic encephalopathy (CTE), concussion management and treatment, and the understanding of the relationship between traumatic brain injury and late-life neurodegenerative disorders, especially Alzheimer's disease.

The researchers didn't find the same IQ dip for people who became frequent users of pot after 18. Although experts said the new findings are not definitive, they do fit in with earlier signs that the drug is especially harmful to the developing brain.

Even though women live longer than men, their brains seem to age faster. The reason? Possibly a more stressful life. As people age, some genes become more active while others become less so. In the brain, these changes can be observed through the transcriptome, a set of RNA molecules that indicate the activity of genes within a population of cells.

The new class of drug, which can be taken orally, is designed to protect the brain by combating the damaging effects of inflammation. Results from early stage clinical trials have yet to be announced, but studies on animals suggest the therapy could be effective against a wide range of conditions which also include motor neurone disease and complications from traumatic brain injury.

Though current trials and several others about to begin probably will be too late to benefit Frost, research is showing the importance of early diagnosis. Once the process that destroys brain cells has begun, the disease is irreversible. But if researchers can find a way to catch it early and slow it down, they think they can prevent much of the worst damage.
