  1. Risk assessment is not intuitive. “There were fewer cars on the road last spring during the height of the pandemic, but traffic fatality rates increased 30% in the second quarter as evidence suggests drivers engaged in more risky behavior, federal officials say. A second NHTSA study of trauma centers found seriously injured or fatal crash victims took risks during the pandemic that included speeding, driving impaired, and not using their seat belts. For example, the study revealed a higher prevalence of alcohol, cannabinoids, and opioids in crash victims during the quarter compared to the months prior to the pandemic.” (link)
  2. “It is believed to be one of the largest COVID-19 outbreaks at any fitness centre in Canada. More than 50 cases, all identified within a single week, all connected to a small, niche spinning studio in downtown Hamilton.” (link)

Brain interface – Neuralink surgical robot

  • The machine consists of three parts. There’s a “head,” which houses automated surgical tools and brain-scanning cameras and sensors, against which a patient situates their skull. A device first removes a portion of skull to be put back into place post-op. Then, computer vision algorithms guide a needle containing 5-micron-thick bundles of wires and insulation 6 millimeters into the brain, avoiding blood vessels. (Neuralink says the machine is technically capable of drilling to arbitrary lengths.) The wires — which measure a quarter of the diameter of a human hair (4 to 6 μm) — link to a series of electrodes at different locations and depths. At maximum capacity, the machine can insert six threads containing 192 electrodes per minute. (link)
