Salamander’s Genome Guards Secrets of Limb Regrowth
With a fully sequenced genome in hand, scientists hope they are finally poised to learn how axolotls regenerate lost body parts.
Scientists Map the Genetic Steps as Eggs Become Animals
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.
Brainless Embryos Suggest Bioelectricity Guides Growth
Researchers are building a case that long before the nervous system works, the brain sends crucial bioelectric signals to guide the growth of embryonic tissues.
Tissue Engineers Hack Life’s Code for 3-D Folded Shapes
Mechanical tension between tethered cells cues developing tissues to fold. Researchers can now program synthetic tissue to make coils, cubes and rippling plates.
