This year’s Nobel Prize in Chemistry has been awarded to three scientists who figured out how to build tiny machines out of molecules. The machines, which include a nano-sized car, are invisible to the human eye and have important implications in medicine and other fields. The researchers — Jean-Pierre Sauvage, J. Fraser Stoddart, and Bernard Feringa — will share the prize equally.
