Two fun stories from Slate:
William Saletan on unmanned drones that can see through walls. (I confess that after a childhood of Ah-nold movies, I am not as blown away by this as I should be. Action flicks ruin one's sense of wonderment in regard to military technology.)
Plus, Nate DiMeo on bad audiobook readers. This one includes a great clip from Brad Pitt reading All the Pretty Horses.
