A web-based method developed by a Stanford-led team was shown to mitigate political polarization on X, the platform formerly known as Twitter, by nudging antidemocratic and extremely negative partisan posts lower in a user’s feed. The tool, which is independent of the platform, has the potential to give users more say over what they see on social media.

Providing year-round access to RSV immunization would minimize the risk of large seasonal outbreaks across the nation, including in both urban and rural areas. That’s according to a new study, published in Science Advances and led by Brown University researchers, which examined differences in viral spread in areas with different population density.

MIT researchers find that large language models sometimes mistakenly link certain grammatical sequences to specific topics, and then rely on these learned patterns when answering queries. This phenomenon can cause LLMs to fail unexpectedly on new tasks and could be exploited by adversarial agents to trick an LLM into generating harmful content.
