[NEWS] Five space science links: ocean worlds, M75, wormholes, neutron stars, black holes, LIGO

  • Gizmodo notes the remarkable depth of the oceans of water worlds, going hundreds of kilometres down (or more!).
  • Motherboard reports on the latest Hubble images of Messier 75, a star cluster that is the vestige of a galaxy absorbed into the Milky Way.
  • Matt Williams at Universe Today notes a new study suggesting that, while traversable wormholes might be physically possible without exotic matter, they would not allow for FTL travel.
  • Paul Sutter at Universe Today notes that a closer study of kilonovas might allow for a better understanding of the interior structures of neutron stars.
  • Ars Technica notes that LIGO may have detected a collision between a black hole and a neutron star.

[BLOG] Some Friday links

  • Centauri Dreams looks at the genesis of ocean worlds. Having a nearly massive star producing lots of radioactive aluminum when it supernovas might be surprisingly important.
  • The Crux takes a look at languages newly forming in the world around us, starting with the Australian language of Light Warlpiri. What does this say about humans and language?
  • D-Brief notes that researchers have managed to create cyborg rats whose motions are controlled directly by human thought.
  • Gizmodo reports on the abandonment by Amazon of its plan for a HQ2 campus in Queens.
  • JSTOR Daily shares the perfectly believable argument that people with autism should not be viewed as people incapable of love.
  • At Lawyers, Guns and Money, Simon Balto writes about how the Ryan Adams scandal demonstrates the male gatekeeper effect in popular music.
  • Tyler Cowen at Marginal Revolution comes up with a list of winners and losers of the Amazon decision not to set up HQ2 in Queens. (Myself, I am unconvinced New York City is a loser here.)
  • Starts With A Bang’s Ethan Siegel explains how, despite not interacting directly with normal matter, dark matter can still be heated up by the matter and energy we see around us.
  • Window on Eurasia notes how, in many post-Soviet countries including the Baltic States and Ukraine, ethnic Russians are assimilating into local majority ethnic groups.

[NEWS] Five D-Brief links: deaf babies, schizophrenia, ocean worlds, planetary systems, quasars

  • The brains of deaf babies process information differently from the brains of their hearing counterparts. D-Brief reports.
  • Do the bacteria inhabiting the human gut have a connection to the likelihood of an individual developing schizophrenia? D-Brief reports.
  • The abundance, or otherwise, of a particular radioactive isotope of aluminum might be necessary for the formation of ocean worlds. D-Brief reports.
  • The existence of the phenomenon of magnetiorotational instability has been proven to exist with regards to planetary system formation. D-Brief reports.
  • Gravitational lensing can be used to discover the earliest quasars. D-Brief reports.
