Fraud Busting, Voting Help, Economic Mobility, and Spinal Implant
- statcheck — R package “statcheck”: Extract statistics from articles and recompute p values. Useful for finding p-hacking and a pile of statistical errors in peer-reviewed papers. (via BoingBoing)
- RoboVote — a free service that helps users combine their preferences or opinions into optimal decisions using state-of-the-art voting methods developed in artificial intelligence research.
- Stacked Deck — This 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)
- Brain Implant Allows Paralyzed Monkey to Walk Again — The 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.
