[8] Research projects at the facility have produced some notable findings, such as the first successful cloning of primate embryos and extraction of stem cells, which was named the number one scientific achievement of 2007 by Time.

[13] Researchers have identified factors that prevent the repair of brain damage caused by multiple sclerosis, complications of premature birth, and other diseases;[14] as well as a key gene that impacts the timing of puberty and can shorten the time span for reproduction.

[17] Findings in the area of obesity research include the role of the hormone leptin in causing/preventing obesity, how leptin resistance occurs and can be reversed,[18] how a high-fat diet during pregnancy affects the foetus,[19] how the natural hormone PYY can cause limited weight loss,[20] and how reduced caloric intake may slow aging and weakening of the immune system.

Staff believed that fighting broke out due to loud noises from construction near the macaques' housing.

Additionally, the USDA reported cracked walls and defects in floor coating in some of the indoor housing areas, which made it difficult to clean and disinfect.

[22][23] In 2014, the USDA reported that a macaque was killed during an imaging procedure after the staff accidentally left a valve closed on the anesthesia machine.

[27] In February 2017, the USDA reported that a baboon broke its hand, which has likely due to a heavy guillotine door.

[27] In February 2018, the USDA reported that a primate was erroneously assigned to a surgical procedure despite being restricted from involvement in any more surgeries.

[28] In February 2018, a primate was not given buprenorphine (used to alleviate pain) or cefazolin (used to treat infections) after surgery, which was part of the approved protocol.

In 2000, animal rights activist Matt Rossell posed as a laboratory technician and later released video footage he had taken from inside the center.

He accused them of violating federal laws and ignoring signs of distress among the rhesus monkeys housed there.

A center spokesman said the behavior of the monkeys seen in the footage was attributable to the infiltrator entering into and creating an unfamiliar environment for the animals.
