Biologists have long puzzled over how organs develop into their final shapes, and the nearly transparent bodies of young sea stars may offer a unique window into the organ development process.

Scientists have, for the first time, used an extremely precise genome editing technique called base editing to study gene ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...
