Medical Xpress / Medical AI may look less biased on paper but not in practice, new study finds
Large language models (LLMs) are only as good as the data they learn from. If their training data contains social biases, the models may unintentionally repeat those biases in their responses. As their use increases with ...
Medical Xpress / Psychedelic drug screen in mice may overlook stress and brain changes
Over the past decades, some medical researchers and neuroscientists have been exploring the possible therapeutic effects of psychedelic compounds, such as lysergic acid diethylamide (LSD) and psilocybin. These are substances ...
