Jellyfish didn’t need novel genes to take an evolutionary leap in complexity.
A primordial developmental toolkit shared by all vertebrates, and described by a theory of the mathematician Alan Turing, sets the growth pattern for all types of skin structures.
Stem cells seem to retain memories of old injuries to improve future healing. When that system goes wrong, chronic inflammation can result.
Renee Reijo Pera has spent decades uncovering how the timing of embryonic development contributes to health and disease.
By measuring mechanical forces inside an embryo for the first time, researchers have shown how a physical “jamming” mechanism assists development.
Once again, body cells reveal unexpected plasticity: In a newly discovered type of wound healing, which some researchers call “paligenosis,” adult cells revert to a more fetal state.
With a fully sequenced genome in hand, scientists hope they are finally poised to learn how axolotls regenerate lost body parts.
The physicist Lisa Manning studies the dynamics of glassy materials to understand embryonic development and disease.
For the first time, researchers have traced the genetic programs that guide the development of each cell in early embryos. Surprisingly, even cells that start out different can end up the same.
