New concentration is the latest example of the University’s commitment to and pre-eminence in the promising field of stem cell research.

A vivid illustration of natural selection at work: Harvard scientists have found that deer mice quickly evolved lighter coloration after glaciers deposited sand dunes atop what had been much darker soil.

For more than a century, scientists have been using electrical stimulation to explore and treat the human brain. The technique has helped identify regions responsible for specific neural functions and has been used to treat a variety of conditions from Parkinson’s disease to depression. Yet no one has been able to see what actually happens at the cellular level when the brain is electrically prodded.

Even as low-carbohydrate/high-protein diets have proven successful at helping individuals rapidly lose weight, little is known about the diets’ long-term effects on vascular health. Now, a study led by team…

Regular use of aspirin after colorectal cancer diagnosis may reduce the risk of cancer death, report Harvard researchers at Massachusetts General Hospital (MGH), Dana-Farber Cancer Institute (DFCI) and Brigham and Women’s Hospital. In today’s edition of the Journal of the American Medical Association, the study’s authors also find that the aspirin-associated survival advantage was seen primarily in patients with tumors expressing the COX-2 enzyme, a characteristic of two-thirds of colorectal cancers.

Harvard Stem Cell Institute (HSCI) researchers at Massachusetts General Hospital (MGH) have substantially improved the odds of successfully reprogramming differentiated cells into induced pluripotent stem cells (iPS) by blocking the…

Political and philosophical differences aside, it’s the economic crisis that’s driving the current national health care reform debate. “Every day the president gets an envelope [that] says, ‘Whoa! Bigger [deficit]…

Since evolving to eat other fish, freshwater fish at the top of the food chain have remained relatively unchanged compared with their insect- and snail-eating cousins, according to new research.…

Harvard researchers at Dana-Farber Cancer Institute have shown that they can engineer mouse and human cells to produce brown fat, a natural energy-burning type of fat that counteracts obesity. If…

An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and…

News release — Mass. General team develops potentially safer general anesthetic A team of Harvard Medical School (HMS) researchers at  Massachusetts General Hospital (MGH) has developed a new general anesthetic…
