What Happens When Scientists Experiment on Themselves?

By Regina Nuzzo

Methodical minds apparently share a compulsive need to discover the truth — personal comfort be damned. When Sir Isaac Newton had a theory about how the eye perceives color, he tested it by sticking a darning needle into the back of his eye socket and poking around until he saw colored circles. German Nobel Prize winner Werner Forssmann performed the first cardiac catheterization surgery — on himself. As a young doctor in Australia in the 1980s, Barry Marshall was convinced that stomach ulcers were caused not by stress or spicy food but by bacteria. To prove his point to the skeptical medical establishment, Marshall gulped down a cup of cloudy broth teeming with helicobacter pylori bacteria. Within a week, he was vomiting daily. Tests showed that his stomach lining was inflamed, which indicated an ulcer could be developing. After a round of antibiotics (his wife insisted he stop the experiment early), the infection disappeared. Today, ulcers are routinely treated with antibiotics, and in 2005 Marshall shared the Nobel Prize in Physiology or Medicine for his work.
