The Nobel Assembly at Karolinska Institutet has awarded the Nobel Prize in Physiology or Medicine jointly to Barry Marshall and Robin Warren for their discovery of the bacterium Helicobacter pylori and its role in gastritis and peptic ulcer disease. Thanks to this pioneering discovery, peptic ulcer disease is no longer a chronic, frequently disabling condition, but a disease that can be permanently cured.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
