"Cyborg Cells Sense Humidity"
news@nature: You need to be a subscriber to read this article in Nature, but the gist of it is:
"living bacteria have been incorporated into an electronic circuit to produce a sensitive humidity gauge.The device unites microbe and machine, taking advantage of the properties of both to make for a supersensitive sensor. 'As far as we know, this is the first report of using microorganisms to make an electronic device,' says Ravi Saraf, a chemist from the University of Nebraska, Lincoln, who developed the 'cellborg' with his student Vikas Berry".
