Zebrafish are highly regenerative, capable of regrowing organs, and even nervous system tissue such as the retina. Research groups investigate these species in search of specific mechanisms of proficient regeneration, with the hope that they can be ported over to human biochemistry. In the best case scenario, mechanisms of this nature could still exist in mammals, retained in order to conduct embryonic development, but actively suppressed in some way in adults, possibly because such suppression reduces cancer risk. The existing evidence is suggestive that this is the case, and the work here adds further support.

Researchers mapped the genes of animals that have the ability to regenerate retinal neurons. For example, when the retina …
