One copy of the Christchurch variant may confer protection against familial Alzheimer's disease

A scientific story that began with a discovery in just one extraordinary patient is now panning out. In 2019, an international team that included researchers from two Mass General Brigham hospitals - Mass Eye and Ear and Massachusetts General Hospital (MGH) - reported on the case of a patient who did not develop cognitive impairment until her late 70s, despite being part of a family at extremely high genetic risk for developing early-onset Alzheimer's disease.

Human infants use the 'helpless' period to pre-train, learn powerful foundation models

Babies' brains are not as immature as previously thought, rather they are using the period of postnatal 'helplessness' to learn powerful foundation models similar to those underpinning generative Artificial Intelligence, according to a new study.
