Genes and the Brain Two related studies revealed gene activity in the brains of people of different genders and ethnicities, from fetaldevelopment to old age. The accomplishment provides a broad foundation for understanding both normal brain development and what goes awry in mental disorders. Messenger RNAs, or transcripts, are transient copies of genes that carry […]
Doctors Miss Alcohol Screening Opportunities Physicians often fail to counsel their young adult patients about excessive alcohol use, a new study found. Excessive alcohol consumption is a common cause of injury and death among young adults.

Prostate Cancer Risk from Vitamin E Supplements A new study found that vitamin E, once thought to reduce the risk of prostate cancer, may actually increase the risk. Prostate cancer is the second most common type of cancer in American men. Their current lifetime risk of prostate cancer is 16%. In 2011, there will be […]

Brain imaging study shows physiological basis of dyslexia Researchers at the Stanford University School of Medicine have used an imaging technique to show that the brain activation patterns in children with poor reading skills and a low IQ are similar to those in poor readers with a typical IQ. The work provides more definitive evidence […]

Imaging study shows little difference between poor readers with low IQ and poor readers with high IQ Last year, Fumiko Hoeft, MD, PhD, authored a study that used sophisticated brain imaging to predict with 90 percent accuracy which teenagers with dyslexia would improve their reading skills over time. Now the Stanford imaging expert has turned […]
Placebo Improves Asthma Symptoms, But Not Lung Function Placebo treatment may make asthma patients feel better but not actually lessen disease, according to a new study. The finding helps clarify the benefits and limitations of the placebo effect. It may also influence how doctors measure successful treatment. The placebo effect is a well-known phenomenon in […]

The Benefits of Being a Beta Male In male baboons, a higher social rank generally brings higher testosterone and lower stress hormone levels. But according to a new study, the highest-ranked (alpha) males have higher stress levels than the second-ranking (beta) males. The finding suggests that life at the very top can be more costly […]
Artificial Human Liver May Speed Drug Development Scientists have devised an artificial human liver that, when implanted in mice, continues to make human proteins and break down certain drugs as the human liver would. The technique could lead to more accurate testing of potential medications. A scanning electron micrograph reveals the complexities of mouse liver […]

Deadly virus reveals a potential weakness A new study of the JC polyomavirus, a devastating pathogen that attacks brain cells in patients with compromised immune systems, has revealed how it binds to its targets, providing a basis for developing drugs to interrupt that process. PROVIDENCE, R.I. [Brown University] — The JC polyomavirus doesn’t strike very […]
