Nobel for Research Once Called "Preposterous"

When two Australian doctors reported in 1982 that bacteria, not stress, caused ulcers, their work was called "preposterous" by colleagues. More than two decades later, this revolutionary notion won them the Nobel Prize for Medicine. The idea that stress caused ulcers was so fixed in medical "fact" and popular culture that it's still heard today, long after its disproof. This case should remind everyone in the scientific world that we still need to look at even "settled" issues with an open mind and go where the evidence leads.
