Researchers at Georgia State University may have published the scientific understatement of the year when saying that their CRISPR experiment with hamsters “found that the biology behind social behavior may be more complex than previously thought.” Using the revolutionary gene editing tech, the GSU neuroscience team discovered that knocking out a receptor of vasopressin — a hormone associated with aggression, communication, and social bonding in both humans and hamsters — instead seemed to supercharge the cute rodents’ worst instincts. The GSU team was surprised to find that their attempts to turn down the aggression in the gene-hacked hamsters made them...
