The Gazette spoke to the center’s director, Jay Winsten.

With the Trump administration halting fetal tissue research at two prominent scientific institutions and new plans to review such research elsewhere, Harvard Medical School Dean George Daley discussed the importance of research using these tissues, which would otherwise be discarded, in creating vaccines and treatments and enhancing our understanding of human biology.

A single microbe accumulating in the microbiome of elite athletes can enhance exercise performance in mice, paving the way to highly validated performance-enhancing probiotics.

In a recent online report, researchers from the Harvard T.H. Chan School of Public Health have compiled 36 expert tips to help make your home a healthier place to live. Happily, most of them are quick fixes that can have a major impact on well-being.

Adding the blood-pressure drug losartan to the intensive chemo and radiation protocol for treating locally advanced pancreatic cancer allowed complete removal of the tumor in 61 percent of trial participants and significantly improved survival rates.

A new study is the first to have observed the complex set of chemical and molecular events that disrupt the microbiome and trigger immune responses during flare-ups of inflammatory bowel diseases (IBD), including Crohn’s disease and ulcerative colitis.
