Laura Helmuth has resigned as editor-in-chief of Scientific American following backlash over profanity-laden posts about President-elect Donald Trump's supporters. Helmuth's comments sparked controversy online, leading to demands for her resignation. Helmuth thanked the publication for her tenure and expressed intentions to take time for personal reflection. Despite her resignation being framed as a voluntary departure, the timing suggests that her social media actions may have played a role in her decision. Scientific American has experienced significant changes under her leadership, including its first endorsements in 175 years for political candidates.
