This is a little something off the beaten track. Nature reported on utensils that measure how relaxed or stressed a person is. The idea is that you can go on a date and monitor how you are doing at making your partner feel comfortable. The technology is similar to a lie detector test, but you got to hand it to them for coming up with a practical and creative application. The technology isn't exactly covert right now. There are too many wires and your date has to hold both the fork and the knife for the electrical current in their body to register. Not to mention you'll have to stash a printer graphing the readouts under the table. Still, geeks in the future could benefit greatly from this technology and its advances.
