We like fish. And we are like fish. Two Michigan State University scientists recently displayed that similarity through art. Ingo Braasch and Julia Ganz, researchers at the university’s Department of Integrative Biology, compiled videos and photos taken during their research into artwork named “Life in Technicolor: The Art of Fish Development and Evolution.” They showed it at a recent MSU science-art exhibition. The art is a byproduct of differentiating types of cells to better study them.
Researchers found that fish can hear human-created, noises and that their ears are harmed by them.
