<strong>Canadian investors create the Power Pillow</strong>


According to <em>Daily Mail</em>, a group of Canadian investors have created the Power Pillow, which can charge your electronic devices on your bed.

That&rsquo;s roughly the amount a person gets from two cups of coffee.


The next day, participants were examined by a new set of pictures; both groups could identify new and old pictures equally, but the caffeinated group was better at distinguishing similar but not identical images.
