[NEWS] Five science links: He Jiankui clones, submoons, ayahuasca, planetary nebulas, black holes
- Chinese scientist He Jiankui, responsible for genetically engineering babies, is along with his team facing serious legal consequences from the Chinese government. SCMP reports.
- A new paper suggests that submoons, moons of a world that is itself a moon, is not only theoretically possible but imaginable in orbit of known worlds including the Moon, Callisto, and Titan. Where are these?
- Is ayahuasca becoming a drug of widespread and legitimate mainstream usage? VICE reports.
- Planetary nebulas, Universe Today reports, are visible for only ten thousand years before their beautiful gases dissipate.
- The interiors of black holes apparently continue to grow indefinitely. (The physics is complicated, as one might expect.) Nautilus has the article.
[NEWS] Six D-Brief links: Sagittarius A*, GRBs, Saturn, Planet Nine, Earth, starlight
- Are the radio jets of Sagittarius A* at the heart of our galaxy pointed directly at Earth? D-Brief reports reports.
- Astronomers might finally have established a firm connection between supernovas and gamma-ray bursts. D-Brief reports reports.
- The length of a day on Saturn has finally been established, at just over 10 hours and 33 minutes. D-Brief reports reports.
- The supposed signature of Planet Nine might be a creation not of a ninth planet but rather by a thick distant belt of objects. D-Brief reports reports.
- Did the collision of protoplanet Theia with the young Earth seen the subsequent world with the materials needed for life? D-Brief reports reports.
- The very idea of an encyclopedia of galactic starlight is profoundly poetic, to say nothing of its scientific uses. D-Brief reports reports.
[NEWS] Five science links: redwood clones, rhea of Germany, Pescadero Basin, deep biosphere, climate
- Motherboard looks at how some ecological activists are cloning the stumps of dead redwoods to produce new trees.
- Rheas imported to the north German plains from South America are thriving, possibly even becoming indigenous. Well done! Deutsche Welle reports.
- Motherboard reports on the unique oceanic ecologies found in the upside-down lakes of the Pescadero Basin.
- The sheer mass of the deep biosphere underneath the Earth is immense, greater than that of humanity. Universe Today reports.
- The Conversation notes how we can use archeology to understand the impact of climate change.
[NEWS] Five science links: geoengineering, Europa probe, ocean worlds, oxygen, black hole portals
- The National Observer takes a look at the challenges, both technological and psychological, facing geoengineers as they and us approach our their hour of trial.
- Evan Gough at Universe Today shares a proposal for a nuclear-fueled robot probe that could tunnel into the possibly life-supporting subsurface oceans of Europa.
- Meghan Bartels at Scientific American notes a new study suggesting that most worlds with subsurface oceans, like Europa, are probably too geologically inactive to support life.
- Matt Williams at Universe Today notes a new study demonstrating mechanisms by which exoplanets could develop oxygen-bearing atmospheres without life.
- Gaurav Khanna writes at The Conversation about how, drawing on research done for the film Interstellar, it does indeed seem as if supermassive black holes like Sagittarius A* might be used as hyperspace portals if they are also slowly rotating.
[URBAN NOTE] Five science links: coffee, CERN, Titan, HCN–0.009–0.044, panspermia
- Motherboard notes that climate change endangers a majority of the coffee species growing in the wild.
- Universe Today notes that CERN is planning to build a successor to the LHC, one a hundred kilometres in diameter.
- A review of data from Cassini, Universe Today reports, suggests the probe saw rain fall in the north polar region of Titan.
- A new analysis suggests that mysterious object in the heart of the galaxy, HCN–0.009–0.044, is actually a black hole massing 32 thousand suns. Universe Today has it.
- Universe Today shares an ambitious proposal for future humanity to use interstellar probes to seed life on potentially hospitable but lifeless worlds, a planned panspermia.
[NEWS] Five science links: desalination brine, Venezuela glacier, Venus, red dwarf plants, AT2018cow
- Wired asks what is to be done with the toxic brine produced by desalination plants.
- This article from The Atlantic tells the story of the last glacier in Venezuela, disappearing as the climate warns and as the county falls apart.
- Universe Today notes the discovery of a mysterious streak in the upper atmosphere of Venus.
- A new study via Universe Today suggests potentially Earth-like exoplanets orbiting red dwarfs stars might not receive enough high-energy photons to support plant life.
- Universe Today suggests that the mysterious AT2018cow event saw the formation of either a black hole or a neutron star.
[NEWS] Five space science links: red dwarfs, zombie stars, LMC, M94, dark matter
- Evan Gough at Universe Today, looking at a study of nearby young red dwarf AU Microscopii, points to findings suggesting that red dwarfs quickly lose volatiles like water in their protoplanetary disks, leaving their worlds sterile.
- Paul Sutter at Universe Today looks at zombie stars, white dwarfs which underwent Type 1a supernovas which did not totally destroy them.
- The SCMP notes a new study suggesting that the Large Magellanic Cloud, the largest satellite galaxy of the Milky Way, will collide with our galaxy in a mere 2.5 billion years.
- IFLScience notes that nearby spiral galaxy M94 is unusually lacking in satellites, leaving interesting hints about the nature of dark matter and its distribution.
- New models of dwarf galaxy formation suggest dark matter can be heated, driven away from a galaxy’s core by–for instance–active star formation. Scitech Daily reports.
