One of the coolest stories we got wind of this week was Ryan Wolfe's bionic plants. Generating their own light, they can grow in total darkness. Now they only need to figure out how to water themselves and they'll be able to get rid of us. Wolfe's creations took a back seat to the story about how Taser is planning to mount video cameras on future stunguns. Don't film me, bro!
