A Gizmag article Two teams close in on Star Trek tricorder-like device dated 12/13 is rather interesting, perhaps even fascinating. They really are making these things that must diagnose some 10 specific ailments plus 3 of 5 others. While I doubt these will work without physical contact, the idea is still cool!
I expect in decades to come we'll see portable DNA readers, which would revolutionise field biology and medicine. Edit: Haha, a quick search tells me they alreadyexist.
I hope the new Star Trek series has some cool technology, cause we seem to be running out of inventions to copy from the show.
I just realized-remembered, Tricorders were used to detect presence of aliens & such. There was a separate medical scanner used to detect injuries & illnesses. :d evil: I do not know if it was a part of the tricorder, though.
