David Baker wird für seine Arbeit zum Design von Proteinstrukturen ausgezeichnet. Mit computergestützten Methoden ist es ihm gelungen, völlig neue Proteine mit gewünschter Form zu entwerfen. Seit seiner Entdeckung sind Forscherteams weltweit in der Lage, immer neue Strukturen gezielt zu bilden. John Jumper und Demis Hassabis werden für die Entwicklung von Google DeepMinds Software AlphaFold2 geehrt, die als Revolution bei der Vorhersage von dreidimensionalen Proteinstrukturen aus der Aminosäuresequenz gilt. Das Deep-Learning-Tool wurde bisher von mehr als 2 Millionen Menschen aus 190 Ländern benutzt.
