The University of Colorado Health Sciences Center has decided to close its controversial monkey lab.
About 40 monkeys have been used in experiments in AIDs, alcohol, and brain research.
CU says most of the animals will go to the Wake Forest University's primate research facility and ten will be given away to an animal rights group.
School officials say the move will be beneficial for the research and the animals, who will get to spend some time outdoors in their new home.
CU will oversee future experiments with Wake Forest University's help, which is located in Winston-Salem, North Carolina.
Animal rights activists have expressed concern about the safety and security of the monkeys at the CU facility.
In August 2004, they were successful in gaining the release of video from inside the lab.
