Researchers have discovered a potential 'pause button' in the earliest stages of human development. Whether humans can control the timing of their development has long been debated. The new study ...

Scientists have discovered a kind of “pause button” in early human development. This biological mechanism has long been known in other mammals, but its discovery in humans could aid IVF procedures.

Researchers recently examined stem cells to see if they could hit the “pause button” on human development. By inhibiting a series of chemical reactions known as the mTOR signaling pathway, the team ...
