At one time, medical researchers conducted their studies only on men. That started changing more than 20 years ago. Now, the National Institutes of Health says more than half of human research subjects are women. But when it comes to research on animals, or even cells, most continues to be done on males. Janine Clayton wants to change that. She’s the Associate Director for Research on Women’s Health at NIH. She joined Tom Temin and Emily Kopp on the Federal Drive to explain the new research policy.
