Research unravels the mystery of how one of the X chromosomes in female embryonic stem cells is silenced.

In a feat of biomedical engineering, researchers create model embryos that could be used to study the mysterious stages of early human development.

A powerful protein inside the body helps naturally repair bone injuries. Increasing it in some patients could jump-start the process, a new rodent study finds.

Engineered polymeric materials known as hydrogels represent a new way to heal intestinal damage — a process that one day might be applied to other injured organs.

By harnessing massive amounts of data on activity within and between snippets of DNA, researchers aim to one day reprogram both healthy and diseased cells.

Scientists can now grow 3-D models of various organs from stem cells, creating new ways to study disease.
