Every cell in the body has the same DNA, but different cell types—such as muscle or brain cells—use different parts of it.

Michael Buck, PhD, professor of biochemistry in the Jacobs School, recently received NIH funding to explore how molecular readers of DNA access and activate seemingly hidden genes.

Unveiling a new chapter in the understanding of human genetics, scientists have discovered a hidden geometric code within our ...

Doctors have begun sequencing newborn DNA to detect dangerous but treatable conditions before any symptoms appear. In pilot ...

Understanding how cells turn genes on and off is one of biology's most enduring mysteries. Now, a new technology developed by chemist Brian Liau and his collaborators at Harvard offers an ...

People looking to lose weight and lower their blood sugar may someday be able to get a single injection that turns their ...

Sections of DNA once dismissed as dormant and useless could in fact be recruited to fight certain types of drug-resistant ...

ETH Zurich scientists have created “MetaGraph,” a revolutionary DNA search engine that functions like Google for genetic data. By compressing global genomic datasets by a factor of 300, it allows ...

DNA shines a light back into the past, showing us things that fossils can't. But how far back can that light extend? Some of the oldest DNA sequences come from mastodon and polar bear fossils about 50 ...

At times, aging doesn’t become evident in wrinkles or in gray hair, it occurs deep inside your body, in cells that have ceased to divide but are still alive. These “zombie cells,” or senescent cells ...

Smith, a microbiologist whose discovery revolutionize the field of genetic engineering, was a Johns Hopkins School of Medicine alumnus and professor emeritus ...
