A gene-editing experiment conducted on hamsters turned the adorable, furry pets into “aggressive” little monsters, researchers said.
Scientists at Northwestern University used controversial CRISPR technology to remove hormone vasopressin and its receptor, Avpr1a, from a group of the critters with the expectation that increase cooperation between the critters, according to the study.
The hypothesis was wrong.
“We were really surprised at the results,” H. Elliot Albers, one of the lead researchers in the study, told Metro.
