BOSTON – New genome-editing technologies developed by researchers in J. Keith Joung’s laboratory at the Massachusetts General Hospital (MGH) have the potential to help understand disease-associated genetic mutations that are based on C-to-G (cytosine to guanine) single base changes. The new base editors are also designed to minimize unintended (“off-target”) mutations that could potentially cause…

Through the ages, the highly infectious disease smallpox has killed hundreds of millions…

Long-term malnutrition might at first seem like a medical condition with an easy fix: access to a wholesome diet rich in calories and nutrients. But many of the children on the receiving end of such interventions still struggle to grow. Even when given enough to eat, they end up shorter than their peers and are…
In the pediatric clinic where I worked for many years in Boston, each room held a clear plastic bowl full of brightly colored condoms. They were there on display, vivid and eye-catching, and part of my job — every provider’s job — was to offer them cheerfully and matter-of-factly and above all non-judgmentally to adolescents…
