Dr Thomas Hartung is an environmental toxicologist at Johns Hopkins University, in Baltimore, who has spent his career trying to replace animal testing with specialised tissue cultures called organoids
and, more recently, with artificial intelligence.
Last May, he announced his most ambitious endeavour yet
—to create a "Human Exposome Project".
It is ambitious because it aims to do for environmental influences on the body what the "Human Genome Project" did for genetic ones.
But it was badly timed because it came shortly after the election of an American administration that is the most hostile to environmental matters in living memory
