Whole-genome sequencing reveals a wide range of UV-induced DNA changes in human skin cells, and lighter skin collects more mutations, sometimes to “sky high” levels.

Paul Cohen of the Rockefeller University describes his study of thousands of people, finding that the energy-burning tissue is tied to a lower risk of for several diseases, including type 2 diabetes, high blood pressure, and heart disease.

Entire organelles bearing DNA move between strains of tobacco that were grafted to one another.

DNA replication errors during cell division cause monozygotic twins to diverge from each other even during the earliest stages of development, a new study finds.

Their relocation explains horizontal genome transfer first described more than a decade ago.

The Sloan Kettering researcher used mutagenic screening to probe genes and molecular pathways, including Toll and Hedgehog, essential to development in fruit flies and mice.

A study using data from more than 80,000 couples finds evidence of indirect genetic effects on traits ranging from smoking habits to mental health.

An additional mutation in the spike protein of the coronavirus may help it elude antibody recognition, and scientists are investigating if current vaccines will protect against it.

Researchers combine organoids, CRISPR-Cas9, and cellular barcoding technologies to identify genes that influence brain size.
