To understand how cranial neural crest cells (CNCCs) help form many more body parts than the skull and facial skeleton, scientists from the lab of Gage Crump created a series of atlases over time to understand the molecular decisions by which CNCCs commit to forming specific tissues in developing zebrafish. The researchers labeled and tracked CNCCs throughout the lifetime of zebrafish. With the help of a new computational analysis they created, they identified genetic signs that point to the specific tissues CNCCs were destined to form. The researchers also identified many of the potential switches that allow CNCCs to form these very different cell types.

Scientists have developed an innovative technique using small wearable sensors to gather data on how people -- who have suffered from a traumatic hand amputation -- use a prothesis versus a transplanted hand in everyday life. So far, the data shows people with a transplanted hand demonstrate a more balanced use of their hands than those who use a prothesis.

Researchers report the creation of an artificial molecule with superpowers. It has the potential to revolutionize nanotechnology -- and it also explains one of Nature's intriguing enigmas; why do we have a right hand and a left hand? The researchers describe their supermolecule as a marriage between DNA and peptides.
