This week’s roundup breaks down the Food and Drug Administration’s decision to revise the safety label for acetaminophen (Tylenol) following the Trump administration’s misleading claims about a link between use of the drug during pregnancy and autism—which were made despite inconsistent data and no proven causation. It also highlights new findings on the safety of COVID vaccination during pregnancy, promising results from a trial of gene therapy for Huntington’s disease and rare animal behaviors, including a notable instance of shark mating and a climate-driven coupling that resulted in a jay hybrid. Plus, the world’s strongest storm of the year reshapes the Pacific typhoon season.
