For New Scientist’s 70th anniversary, we asked three Nobel laureates to challenge our readers in a quiz about their prize-winning discoveries. The question setters are:

at the University of Western Australia, winner of the Nobel prize in physiology or medicine in 2005 for discovering the role of Helicobacter pylori bacteria in gastritis and peptic ulcer disease.

, founder of the Innovative Genomics Institute in Berkeley, California, who won the Nobel prize in chemistry in 2020 for the development of CRISPR gene editing.

at the University of California, Berkeley, who won the 2011 Nobel prize in physics for measuring the expansion of the universe through observations of distant supernovae.

Good luck!
