Mounting evidence supports ayahuasca’s potential to improve mental health, but its long-term effects are shaped by both individual mental health history and the context in which the psychedelic is used, according to a study published on April 30, 2025 in the open-access journal PLOS Mental Health by Óscar Andión from Research Sherpas, Spain; José Carlos Bouso from the International Centre for Ethnobotanical Education, Research, and Services (ICEERS) and the University of Rovira i Virgili, Spain; Daniel Perkins from the University of Melbourne and Swinburne University; and colleagues.

A new 3D "atlas" of the mouse brain, developed by Duke University School of Medicine and collaborators, promises to sharpen scientists' ability to measure brain changes and share findings across studies of diseases like Alzheimer's. The Duke Mouse Brain Atlas combines microscopic detail from multiple imaging techniques into a living, distortion-free map—offering a powerful new tool for research and discovery. The open-source atlas, reported April 30 in Science Advances, is already helping scientists track neurodegeneration in mouse models.
