In an effort to understand how genes work, a collaborative study has identified a gene that regulates glucose levels. The results may provide further understanding of the underlying causes of diabetes.

Scientists have developed a new approach to treating such autoimmune diseases as irritable bowel syndrome using genetically-engineered regulatory T cells. This approach may be adapted to a number of autoimmune diseases, as it can be used treat the disease without knowing its exact cause.

Chronic inflammation of the intestine or stomach can damage DNA, increasing the risk of cancer, MIT scientists have confirmed. Chronic inflammation accelerated tumor formation in mice lacking the ability to repair DNA damage.

As DNA sequencing becomes cheaper, it will become common for people to have their complete genomes sequenced. Personal genomes will not only tell people about genetic susceptibility to cancer and heart disease, but will also tell them which vitamins and how much can improve their health. A new study shows that one enzyme can be tuned up with vitamins, suggesting that one day we all may take personalized vitamin supplements.

Challenging the long-standing belief that breast-feeding equally protects all babies against disease, new research suggests that when it comes to respiratory infections, the protective effects of breast milk are higher in girls than in boys.

The use of electrical impulses to stimulate weak or paralyzed muscles, called functional electrical stimulation, is often used to help stroke or multiple sclerosis patients to walk.

Long-term, heavy cannabis use may be associated with structural abnormalities in areas of the brain known as the hippocampus and amygdala, according to a new article in the Archives of General Psychiatry.

A vaccine aimed at inducing immunity to the most common and deadly type of brain tumor may stave off recurrence and more than double survival in patients, according to a new study.

As the United States continues to import increasingly more of its food from developing nations, we are putting ourselves at greater risk of foodborne disease because many of these countries do not have the same sanitary standards for production, especially in the case of seafood and fresh produce.

Peptide arrays are powerful tools for developing new medical substances as well as for diagnosis and therapy techniques. A new production method based on laser printing will enable the potential of peptide arrays to be effectively utilized for the first time.
