The NIH Council of Councils Working Group on Tuesday Jan. 22, 2013 approved a proposal, which also calls for major cuts in grants to study chimps in laboratories and no return to breeding them for research. Government scientists have agreed that all but 50 of hundreds of chimpanzees kept for federally funded research should be retired from labs and sent to the national sanctuary.
