Richard White is an oncologist at Children’s Hospital Boston and instructor at Harvard Medical School — but lately, he’s also gained fame as an animal breeder.

This spring, White and his colleagues announced that they had bred a new, see-through, zebrafish. The animals’ transparent skin gives scientists a clear view of developmental processes, such as tumor growth, in real time — making it a valuable tool for White and other researchers.

The NewsHour update doesn’t say whether there’s any new information about biology yet uncovered from using this new strain that is more transparent than other existing transparent strains. But, it’s neat that scientists can peer into the embryos and larvae and get a clear view of their development.
