Edelman's prostate screening sounds terrible. But breast cancer screening is no ideal to be imitated. For the past twenty years, the big machines that xray breasts have seen little improvement. Twenty years ago, they demanded to squish my breast to a thin pancake (OUCH!) and they still do. Yet if you think about the improvements to computer image-processing and data analysis in the past twenty years, it's hard to imagine why those machines couldn't be updated to make tests less painful.

I heard a shocking but related story from a physicist who found a mathematical way to improve PET scan imaging (or maybe it was CAT scan, not my point here) based on some of his research for imaging physics stuff. A big company that makes the big scanning machines bought his patent--and disappeared it. Their patients' diagnoses didn't get one whit better but their company profits were better insulated against a new company's bringing in better technology.

Hey, if The Economist or any other online pubs want love links they might as well have their new media editor interview at Conversation Agent ;-)
