Of the many qualities that make the zebrafish a model organism, the fact that it shares 70% of the genes humans have makes it an ideal candidate for developmental biology research.

New strategy helps build synthetic organs from scratch. This enabled the researchers to grow functioning liver tissue in the lab that could be transplanted into mice with liver disease.
