To reveal the hidden norms encoded in popular AI chatbots, UC Berkeley researchers turned to the internet’s favorite source of moral dilemmas: Reddit’s “Am I the Asshole?” (or AITA) forum. In a recent study, which is published as a pre-print, the researchers confronted each of seven different large language models (LLMs) with more than 10,000 real-world social conflicts posted to the forum and compared their responses to those of Reddit users.

UCSF is hosting a family-friendly Touch-A-Truck fair at the new Parnassus Heights campus construction site on Saturday, giving local children a chance to take part in the project and see the big trucks up close.

The International Society for Stem Cell Research (ISSCR) convened its first-ever meeting with Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) and Korea’s Ministry of Food and Drug Safety (MFDS), marking a major milestone in the Society’s global regulatory advocacy efforts. The meeting took place on 7 November 2024. The dialogue brought together leaders from the ISSCR and regulatory authorities in Asia to discuss key considerations shaping the safe and effective development of pluripotent stem cell (PSC)-based therapies. Discussions focused on the manufacture of PSC banks as starting materials for allogeneic therapies, the genetic assessment of PSCs, and jurisdictional differences in guidelines for biological ancillary materials.
