writes to tell us the BBC is reporting that the Nobel prize for medicine has been awarded to two Australian scientists
for their work with ulcers. Their research has shown that the majority of ulcers are caused by bacteria and can be cured with a short-term course of drugs and antibiotics. From the article: "Dr Marshall proved that H. pylori caused gastic inflammation by deliberately infecting himself with the bacterium. The Nobel citation praises the doctors for their tenacity, and willingness to challenge prevailing dogmas."
