Attacks against researchers by animal rights extremists have steadily increased in recent years. More than 70 such attacks occured in 2006 alone, according to data collected by the Foundation for Biomedical Research, a Washington, DC–based nonprofit that aims to serve as the voice of scientific reason in the ongoing debate that surrounds animal research. Frankie Trull currently heads the foundation, which she established in 1981. She explains to Nature Medicine why she has devoted her career to improving the public understanding of the essential role of lab animals in medical research and discovery.
