World Day for Laboratory Animals: Advancing Science Without Animals

Each year on April 24, scientists, advocates, and policymakers around the world mark World Day for Laboratory Animals—a chance to reflect on the millions of animals used in research and testing and a call to accelerate the transition to better science.
