Calculating the Speed Limit of Quantum Information. “As described in a paper published in the current Physical Review Letters and authored by NIST scientists, the increase in speed allowed by quantum entanglement-based processing is more likely to be linear than exponential. This is the difference between a steady (if extremely steep) increase and a stratospheric upward curve.”

Astronomers Clash Over A Giant Telescope On A Sacred Hawaiian Mountain. Construction stopped Tuesday on the $1.4 billion Thirty Meter Telescope in the face of protests from Hawaiians who believe its location is sacred. The fight has astronomers asking whether a pristine view of the stars trumps the beliefs of people on the ground.

Mixing Math and Magic: “What happens when a magician who does card tricks becomes a Stanford math professor? Persi Diaconis has used his intuition about card shuffling to help decode messages passed between inmates at a California state prison and to analyze Bose-Einstein condensation. He and his students and colleagues have successfully analyzed just about every type of shuffle people use in ordinary life, except one: “smooshing.” Now he is on a quest to solve it, which could help scientists better understand fluid mixing.”

Dark Matter May Not Be Completely Dark, New Study Concludes. I mean, it’s really dark, but not totally dark: “The “darkness,” in this case, refers to the matter’s ability to not interact with itself, or anything at all but gravity.” Could partially interacting dark matter have been discovered?

Granular Materials Could Thwart Missiles. The harder a projectile hits a granular substance like sand, the more that material acts like a solid, effectively repelling the intruder.

Lots of folks have been talking about a new paper in PNAS showing that women are less likely to be hired than equally qualified men when they apply for tenure track position, producing misleading clickbaity headlines crowing that gender bias in hiring is a myth. Like anything related to gender issues, discrimination, etc., these days, the discussion was sharply polarized. But here are a couple of good pieces offering some balanced perspective. First, remember that some good news about hiring women in STEM doesn’t erase sex bias issues. Then read Maria-Claire McShanahan’s fantastic in-depth analysis of the study itself — something few people commenting bothered to do — and the unfortunate media framing that followed. And heed her conclusion: “I would ask us all to take care in how we share this story and how we talk about it. Potentially interesting, sure, but also potentially damaging when presented as something that it isn’t.”
