Two at a time

With just one shared award, Australia has doubled the number of living Nobel Prize winners that we had last week. Congratulations to Professor Barry Marshall and Dr Robin Warren, and kudos to Prof. Marshall who even went to the extent of drinking a glass of ulcer-causing bacteria and giving himself gastritis to prove his point.

(Our other living Nobel laureates are Peter Doherty and John Cornforth -- and I will admit to cheating on the last one and looking it up, as I was only a little tacker when he won his prize in 1975.)
