Also discussed: "Embiggen" added to the dictionary, oil companies buy Utah monuments for drilling, Amazon patents drones to recognize flailing and screaming gestures, the Texas-sized (?) Pacific Garbage Patch, earliest North American footprint found, China face IDs and tickets jaywalkers, mind-reading technology, new human organ discovered, and turtles develop karate-chopping flippers. Cowabunga, dude!
