Eureka Alert notes that while fish and lizards have multiple sets of teeth during their lifetime, most mammals have two with mice having only one. Reportedly, Professor Abigail Tucker and PhD student Elena Popa of King's College London were able, using sophisticated genetic techniques, to activate the creation of additional teeth, with obvious human applications.

Professor Tucker explains: "This is relevant to human tooth replacement, as structures similar to the RSDL have been identified next to the permanent teeth during development. In normal development of our teeth, therefore, the second set or permanent tooth may inhibit the generation of a third set of teeth."

Elsewhere, researchers were able to use CRISPR to cure mice of progeria and deafness.
