Artificial Eggshell Lets Chicken Embryos Develop Outside the Shell

Colossal says chick embryos developed normally after transfer into an artificial shell device.
The system could improve continuous observation of vertebrate development.
Its value may extend beyond de-extinction into developmental biology research.

Shared Leaf-Growth Rules Link Mosses and Thale Cress Across 400 Million Years

A Science Advances study compared mosses and Arabidopsis thaliana.
The organisms have evolved separately for about 400 million years.
The study reports similar cellular dynamics during leaf formation.
The finding points to shared developmental principles across distant plant lineages.

Scientists identify a stemness checkpoint that appears to stabilize stem cell identity

A study in Cell Research identifies a “stemness checkpoint.”
The checkpoint is described as helping control stem cell identity.
The finding appears to span multiple stem cell types and developmental stages.
The result advances a central concept in stem cell biology.
