U.S. To Require Gender Equality For Medical Lab Rats

"The U.S. National Institutes of Health—one of the biggest funders of biomedical research in the U.S. and the world—will now require the studies it funds to have equal numbers of male and female lab animals. It's even requiring gender balance in studies done in cells in petri dishes. Yep, that means female and male lab rats will now have equal opportunity to die for science."
