Mission to Bennu may help defend Earth, and there may be water there — Bennu is a 487.68m-wide asteroid that orbits the Sun relatively close to the Earth. NASA’s OSIRIS-REx mission won’t just take pretty pictures of the asteroid Bennu, it will also help scientists learn whether the rock will one day threaten Earth. OSIRIS-REx spacecraft also detected evidence of water on its target just a week after arriving.
~ To wetly threaten Planet Earth …
Quark soup droplets expand like Big Bangs — Stars and galaxies didn’t form right away. Scientists think that matter was initially a near-perfect fluid of quarks, the smallest known component of atoms. They have found evidence of these fluids in high-energy particle collider experiments. Now, evidence continues to mount that these liquids can form in unexpected ways, yielding tiny droplets that flow outwards explosively, like liquid Big Bangs in miniature.
~ Sounds like messy dining, though.
Experimental gene therapy stops mice getting fat — Researchers at Flinders University knocked out a gene known as RCAN1 in mice, hypothesising this would increase “non-shivering thermogenesis,” which “expends calories as heat rather than storing them as fat” – the mice were fed a high-calorie diet and did not gain weight. In particular, the modified mice did not store fat around their middles (a phenomenon associated with many health risks, including cardiac problems) and their resting muscles burned more calories.
~ Despite that, I don’t think I can bring myself to eat those skinny, gene-altered mice.
What did Minnesota kids from the year 1904 think would happen by the year 1919, or even 2019? They imagined fancy airships in the sky, “automobiles for everything,” and wondrous house-cleaning robots. They even imagined trips to Mars by the year 1919. Seriously.
~ I already have a wondrous house-cleaning robot. Me.
Incan temple virtually recreated — The 1500-year-old Pumapunku temple in western Bolivia is considered a crowning achievement of Mesoamerican architecture, yet no one really knew what the original structure actually looked like. Until now.
The stonework of the temple is considered so precise that ancient alien enthusiasts claim it was made by lasers and other extraterrestrial technologies.
~ The technique can now be used on other sites.
Two Chinese stalagmites enrich radiocarbon dating — Owing to the discovery of two stalagmites in a Chinese cave containing a seamless chronological atmospheric record dating back to the last Ice Age, radiocarbon dating will now be better.
An unbroken, high-resolution record of atmospheric carbon-12 and carbon-14 was found in a pair of stalagmites located within Hulu Cave near Nanjing, China, according to new research published in Science.
~ Now we can calibrate back a lot further.
