Spotlight: AI in healthcare ▶ Watch
AI systems can examine medical images to help detect conditions such as diabetic eye disease and some cancers, in some studies matching specialist performance on narrow tasks. DeepMind's AlphaFold predicted the 3D structures of a vast number of proteins, a breakthrough recognised with a share of the 2024 Nobel Prize in Chemistry. Even so, AI supports doctors - it does not replace medical judgement.
Spotlight: AI in education ▶ Watch
An AI tutor never gets tired of questions. Students can get explanations at their level, practise in any language and receive instant feedback. Teachers use AI to prepare lessons, create quizzes and differentiate material. The key is to use AI to learn, not to skip the learning.
