NIH director to step down by end of the year

The Director of the National Institute of Health, Francis Collins, has resigned after 12 years in the position. On Tuesday, the 71-year-old said he made the decision with the belief that “no single person should serve in a position for too long” and added it was time a new individual led the agency.
