On April 15th, the first Twitter messages ever to be sent through the power and will of someone's brain were posted.
Adam Wilson and his lab have created a device that you hook up to your head to communicate messages via computer screen. You focus on a letter/symbol on the screen, and the device can detect which one you are focusing on, and brings up the letter. Then you focus on the next letter, and so on.
This could be used to allow people to communicate who for some reason can't.
