Scientists in the Brivanlou lab used light-inducible gene expression (yellow circle) and embryo models to demonstrate that, at the start of gastrulation, body-axis formation requires an interplay ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...
