Man infects himself with computer virus
Update: Engadget article
Of course, the news makes this more sensational than it is, but the fact that implanted/embedded chips in people could be used to transport data and therefore malware is very real. Additionally, software being used to manage biological functions within people also need to be scrutinized by the vendors. And, of course, the best way to do this is to make sure that there's a review by industry experts, not by using some proprietary method of protecting the system/chips/data.
Kinda funny that I'm commenting on this, now that I think about it, given my domain name, LABrat.com. :-)
