Scientists have a weird hunch about why the Sun spins too slowly — Physicists have long known that the Sun spins, like the Earth. But a few decades ago, they realized the surface of the Sun spins more slowly than their models predicted – not by a lot, but enough to signal that something they didn’t understand was going on. This kicked off a solar mystery.
A team of astronomers has stared into the Sun long enough that they think they’ve found the source of the slowdown.
~ I’d suspect tiredness.
NASA’s Trojan side mission —OSIRIS-REx is one of the busiest spacecrafts in the solar system. It blasted off in September 2016, and has been getting ready to rendezvous with the object of its mission, an asteroid called Bennu, to bring back samples to Earth. But before the spacecraft links up with Bennu in 2018, it’s been assigned a side project: for 10 days this month, OSIRIS-REx will investigate whether or not Trojan asteroids exist at certain points in Earth’s orbit called Lagrange points.
Space junk — An experimental Japanese mission to remove dangerous debris from orbit has ended in failure. It’s a frustrating setback given the mounting risks posed by the nearly two million bits of junk currently swirling around our planet.
~ Here’s my idea: stick a powerful magnet on one, and when it’s collected a few others, deal with them together.
Losing freeways — Rip out eight lanes of freeway through the middle of your metropolis and you’ll be rewarded with not only less traffic, but safer, more efficient cities … it’s true, and it’s happening in places all over the world.
~ This is apt, as I feel like a loser every time I get trapped on Auckland’s.
Maths is beautiful in theory, miraculous when applied, and awe-inspiring at every turn — Appreciate the diversity and implications of math. While an artistic temperament is often considered the exact opposite of the kind of personality that loves complicated equations, pure mathematicians are really just a bunch of lunatics endlessly working with abstraction and beauty. And folks who work in fields of applied mathematics often end up finding a use for those abstract ideas.
~ I used to use a calculator, but now Siri does all my maths.
Bees are dying but … tiny bee drones — We rely heavily on bees and other species to pollinate our plants, and though there isn’t global data, there have been enough local die-offs to spark widespread concern, according to a report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. Now, a team of scientists from the National Institute of Advanced Industrial Science and Technology (AIST) in Japan has engineered drones featuring a specially-engineered adhesive to pick up and deposit pollen.
~ I already saw this on Black Mirror.
Huge US diversity thanks to 770,000 vials of spit — Genetics have been used to track historical migration before, but this new study gives us a look at recent history. Where the data is most remarkable is in its granularity: the ability to point not just to France but to specific regions of France, and track the migration of those groups of people over time.
~ And surprise! Despite Trump’s henchmen’s ideas, the US is very, very diverse. All that spit seems most appropriate.
