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.

Study examines how colibactin causes cancer

In an effort to understand how colibactin, a compound produced by certain strains of E. coli, may be connected to the development of colorectal cancer, Harvard researchers are exploring how the compound damages DNA to produce DNA adducts.
