For some, animal testing is ‘just science’. For others, it’s just not right

Animal testing is still widely viewed as the least worst option for biomedical progress, even though researchers know more about animal sentience than ever, and animal rights movements – including vegetarianism and veganism, as well as bans on animal-tested cosmetics – have made significant gains. In Test Subjects, the scientists Frances Cheng, Emily Trunnell and Amy Clippinger each explain how completing their PhDs marked a profound turning point in their approach to animal testing. Now working with the animal rights organisation PETA, which executive-produced this short documentary, they detail their personal journeys from using animals in the lab to researching and promoting alternatives. With sensitivity and emotion, the UK director Alex Lockwood explores their experience of staking out an unpopular position in the scientific community, as well as the anguish that animal experimentation can inflict upon researchers and test subjects alike.
