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. Kids will receive construction hard hats and be able to climb on the construction equipment used for the expansion.

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. 

A recently published study – the largest to date – led by researchers from Ann & Robert H. Lurie Children’s Hospital of Chicago found that impaired motor coordination is the primary driver of autism-related differences in imitation ability, with other overlapping causes contributing to a lesser degree.
