- The hyoid bone is unique in the human skeleton for being free-floating; it does not share a joint with any other bones, and is only distantly connected to the skull through the Stylohyoid ligament. It is mostly held in place by muscle and cartilage, and helps control the tongue and larynx. Unlike a human’s clavicle, a cat’s clavicle is similarly free-floating, allowing a cat’s shoulders to squeeze through openings as narrow as their skull.
…was the first of a series of missions to Mars that included rovers, and was the first successful lander since the two Vikings landed on the red planet in 1976…In addition to scientific objectives, the Mars Pathfinder mission was also a “proof-of-concept” for various technologies, such as airbag-mediated touchdown and automated obstacle avoidance, both later exploited by the Mars Exploration Rover mission. The Mars Pathfinder was also remarkable for its extremely low cost relative to other robotic space missions to Mars.
Here’s Cindy Healy talking about UNIX administration for Pathfinder.

- Good write-up about the boys rescued from the cave in Thailand.
18-year-old Ewin Tang has proved that the Kerenidis and Prakash recommendation algorithm does not provide an example of an exponential speed up in quantum machine learning. Here’s his advisor Scott Aaronson on the implications:
Prior to Ewin’s result, the KP algorithm was arguably the strongest candidate there was for an exponential quantum speedup for a real-world machine learning problem. The new result thus, I think, significantly changes the landscape for quantum machine learning; note that whether KP gives a real exponential speedup was one of the main open problems mentioned in John Preskill’s survey on the applications of near-term quantum computers
