These experiments involve restraining and drugging mother macaque monkeys so that scientists can take their newborn babies. After enduring the trauma of being separated from their mothers and uprooted from the wild, the babies are put in solitary confinement where they are mercilessly terrorized with anxiety-inducing stressors like live snakes, skin biopsies, and brain scans. Once they’ve been used and abused, scientists kill them before the age of two.

This despicable scene seems like something out of a horror movie, but it’s all played out in real life … on innocent animals.
