New research provides evidence of the vicious cycle created when an obese individual overeats to compensate for reduced pleasure from food.

The ability to efficiently generate patient-specific stem cells from differentiated cells and then reliably direct them to form specialized cells (like neurons or muscle) has tremendous therapeutic potential for replacing diseased or damaged tissues. However, despite some successes, there have been significant limitations associated with existing methods used to generate human induced pluripotent stem cells.

Early life stress, such as an extreme lack of parental affection, has lasting effects on a gene important to normal brain processes and also tied to mental disorders, according to a new animal study.

A new study suggests that mothers who consume a diet high in trans fats double the likelihood that their infants will have high levels of body fat.

A new approach to anchor teeth back in the jaw using stem cells has been developed and successfully tested in the laboratory for the first time.

Although first responders willingly put themselves in harm's way during disasters, new research indicates that they may not be as willing -- if the disaster is a potentially lethal pandemic. In a recent study, researchers found that more than 50 percent of the first responders and other essential workers they surveyed might be absent from work during a serious pandemic, even if they were healthy.

New research shows that an intravenous treatment -- called dexamethasone -- may cut a person's risk of dying from bacterial meningitis.

Researchers have published the first report using imaging to show that changes in brain tissue can occur in breast cancer patients undergoing chemotherapy.

In a new study, researchers report evidence of an association between father's incarceration and substantially elevated risks for illegal drug use in adolescence and early adulthood.

Researchers have discovered that women treated for breast cancer while pregnant -- long associated with a worse outcome -- in fact have improved disease-free survival and a trend for improved overall survival compared to non-pregnant women treated for the disease.
