Harvard study unlocks a key to regeneration

Led by Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava, a team of researchers is shedding new light on how animals perform whole-body regeneration, and uncovering a number of DNA switches that appear to control genes used in the process.

Harvard researchers look toward nature to beat cancer

Every year, more than 18 million people around the world are told, “You have cancer.” In the U.S., nearly half of all men and more than one-third of women will develop some kind of cancer during their lifetimes, and 600,000-plus die from it annually. Despite the billions of dollars and countless new treatments that have […]
