Researchers from the University of Southern California want to use cellphones to help the obese shed weight. The idea is to hook up obese kids to a “mobile body network,” consisting of a device to measure the skin’s electrical conductivity along with a heart-rate monitor, accelerometer, blood glucose reader and GPS for location, and connecting it with a battery sensor on the child’s body.

The system uses a Smartphone to send the collected behavioral data to the university’s computers, where it is then figures out what the information means. If your kid is laying around, text messages will be shot his way to get him to do get off his ass and do something.

Are you doing stuff that you shouldn’t be doing? If so, then you probably don’t want to get caught doing that stuff. We don’t want to know. But the Ghost Pigeon can help you keep things on the down low. It’s a piece of cloaking software that masks all incoming and outgoing calls and text messages on your handset so people can’t examine your phone and discover who you’ve been in contact with or even when.

It’s not all shady stuff. It’s likely useful for employees searching or interviewing for a new job on their company phone, or for CEOs negotiating a golden handshake and stuff like that. I mean, not everybody is a drug dealer or a smuggler etc.
