Artificial intelligence systems are increasingly being used to help test new drugs and chemicals.
From animal lovers to laboratory technicians, no-one enjoys subjecting animals to scientific testing.Researchers have long sought non-animal alternatives. Artificial intelligence systems are now accelerating this work.
Thomas Hartung is a toxicology professor at Johns Hopkins University in the US, and also the director of the Center for Alternatives to Animal Testing. He says: “AI is as good as a human, or better, at extracting information from scientific papers.” Prof Hartung adds that while software systems have long been used in toxicology, AI is providing an “enormous leap forward” in both power and accuracy.
For example, arthritis medicine Vioxx passed the animal testing stage, only to then go on and ultimatelyafter studies showed that long-term usage by humans led to an increased risk of heart attack and stroke. She explains that new medicines are currently first tested both on rats and dogs to check for potential toxicity, before human trials potentially start.
