New method to assess toxicity of chemical products likely to put end to animal testing

A team of scientists led by Thomas Hartung, from  Johns Hopkins University of Baltimore, has developed a method to assess the toxicity of chemical products without performing tests on animals. The method has been introduced this week at the EuroScience Open Forum in Toulouse, which is now about to end, and is based on an AI program using a database of 800,000 tests with 10,000 different chemical molecules. The program, named Rasar system–acronym of Read-Across-based Structure Activity Relationship–uses a continuous learning procedure to assess toxicity on eyes and DNA and is 87% accurate. Radar has been co-developed with Underwriters Laboratories, an independent company who has committed to make it available and free to everyone.
