Alán Aspuru-Guzik takes a lot of calls these days from scientists considering an exit from the United States. Aspuru-Guzik, a theoretical chemist, left Harvard University, in Cambridge, Massachusetts, during Donald Trump's first term as US president, from 2017 to 2021, to join the University of Toronto in Canada and hasn't looked back. "I'm the happiest guy here," he says. Aspuru-Guzik left because he didn't agree with Trump's politics and policies.

It feels strange, he says. Two months ago, I would have been thrilled to talk about the work. Now, I don't feel comfortable even mentioning these things existed.
