Best of Last Week – Dark matter acting like pions, changes to astronaut skin and illusion of knowledge by experts

(—It was an interesting week for physics as a team made up of international researchers came up with a new theory that says dark matter acts like a well-known particle—they suggest it has similarities to pions, which bind atomic nuclei together. Also, a macroscopic quantum phenomena was discovered in ice by a team of researchers in China—at very cold temperatures the ice behaved in a way that could only be explained by quantum tunneling, a rare example of quantum phenomena emerging on a macroscopic scale. —> Read More
