Technically its not a dupe, its still in the firehose. Additionally this had the better of the 2 summaries. You'll notice MANY dupes on the firehose, so its not even a big deal.

Learn how slashdot works before telling editors they're doing it wrong. Oh wait, carry on.

I'd rather have the link to Purdue since they're the ones conducting the research, rather than some tech news blog. Just because something came first, doesn't make it the better choice. A better summary or a better link should always win out over earlier submission in my book.

Well this is news to me. I have a family history of lung and colon cancer that metastasize and kill you. I think inventions like this are wonderful but it leaves me a simple question. How much does a scanning cost and is it covered by insurance? Considering I have none and would have to pay out of pocket; I would like to know? Another question. If cancer cells are detected very early on; what experimental treatments are there? For the most part, medical science deals with cancer when it's progressed to dangerous levels. I would hate to be given a diagnosis of pre-brain cancer and be told you have 3 years to live. It would drive me nuts!
