Strange doings, from atoms to galaxies to homicidal grandchildren

Still playing catch-up here after last weekend's Capclave. So: for this week's post, I'm sharing -- with the most minimal of introduction -- a potpourri of physical-sciences news that I expect will appeal to regular SF and Nonsense visitors. (And if none of these links/headlines grabs you, well, I'll just have to live with that.)

From Phys.org, about the quantum-mechanical underpinnings of superconductivity: For first time, researchers see individual atoms keep away from each other or bunch up as pairs.

Again from Phys.org, about the ever-growing enigma that is Tabby's Star: Our galaxy's most-mysterious star is even stranger than astronomers thought.

From physicsworld.com, about whether inferred-but-undetected dark matter or a Modification Of Newtonian Dynamics (MOND) best explains observed gravitational anomalies, such as the rotation of galaxies: Correlation between galaxy rotation and visible matter puzzles astronomers.

Again, from physicsworld.com, about the finale to a very successful journey to a comet: Rosetta mission ends with comet crash.

And finally, from Cosmos.com, about paradoxes and time-travel theory: Computer solves a major time travel problem.

Now tell me something in that compilation didn't pique your interest ;-)
