  4. Stacked DeckThis paper offers an overview of the interplay between declining upward mobility and growing political inequality, which we show is a self-reinforcing phenomenon. It reports on a growing body of new research on this nexus. Feedback loops are important in society as well as software. (via Hamish MacEwan)
  5. Brain Implant Allows Paralyzed Monkey to Walk AgainThe neuroprosthetic device implanted in the monkey’s brain correctly interprets activity generated by the motor cortex, and relays this information to a system of electrodes placed over the surface of the spinal cord, just below the injury. A burst of just a few volts, delivered at the right location, triggers specific muscles in the legs. Monkeys implanted with the device were able to walk within six days of the spinal cord injury. Paralyzed monkey version of “I Know Kung-Fu!”.
