The finding, which dramatically alters the prevailing theory of Alzheimer’s development, also explains why some people with plaque build-up in their brains don’t have dementia. The study is published online today in [...]

It’s a complicated question, made more difficult by trying to measure how teachers make decisions in the classroom and what impact those decisions have on what pupils learn. In a new report for the Sutton Trust, we have tried to set out how great teaching leads to great learning. Our overall [...]

Scientists believed these two brain events were separate phenomena because they outwardly affect people very differently. Seizures are [...]

Nonetheless, scientists from the Max Planck Institute for Evolutionary Biology have now demonstrated that each [...]
