In the tropics malaria is a common disease that causes high fever and other symptoms. By the middle of the 19th century, it was clear that many diseases are caused by microorganisms, and a great many people suspected that malaria was caused by a bacterium. After examining blood from people infected with malaria, Alphonse Laveran in 1889 was able to definitively show that malaria is caused by another type of single-celled organism, a protozoan of the Plasmodium family, which attacks red blood cells. He also identified other single-celled parasites that cause other diseases.
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.
