Before drugs are tested on humans, they first go through pre-clinical tests on animals. Because humans and animals don't have identical gastrointestinal tracts, however, the way in which the drugs are absorbed by the body often differs between the two. A scientist from the UK's University of Huddersfield hopes to address that discrepancy, with his "gut simulator."
