Space oddity Oumuamua probably shard of Pluto-like world, scientists say
Interstellar visitor likely made of frozen nitrogen, cookie-shaped rather than cigar, and not a comet or asteroid – while some stick to alien theory

@stargazer so what do you for a job...oh I fly drones...for NASA...on Mars.

@taniwharugby Unique work stories!

Well - that led me to ask "Helicopter? What? Does Mars have an atmosphere?" - and rather than taking the normal approach and just ask here - I actually bothered to type it into a different tab, and get an immediate answer, which led to...
- So yes, Mars has an atmosphere - albeit much thinner than Earth's
- But - it used to have a much thicker atmosphere, much more like Earth's (which meant water, blah blah, the dry riverbeds, blah blah, building blocks of life, blah whatever)
- So... if Mars lost most of its atmosphere, ending up a dry husk of a planet... could Earth do the same...?
- Yeah... that's already happening - but likely to take about a billion years, so... probably not Greta's priority just yet

Geez.
Bees learn to play golf and show off how clever they really are
I'll show you ball skills It’s a hole in one! Bumblebees have learned to push a ball into a hole to get a reward, stretching what was thought possible for small-brained creatures. Plenty of previous studies have shown that bees are no bumbling fools, but these have generally involved activities...

Had no idea they disappeared for this long... crazy.

Periodical cicadas burrow into the ground after hatching, some digging as far as 8 feet (2.4 meters) below ground. While underground, the nymphs suck the sap from tree roots for nourishment and after 17 years, they emerge and climb trees and shrubs, where they shed their crunchy skins and harden into maturity. The males make a cacophony of sounds in the tree tops as they look to mate.

@bones The cool thing is how the different species stay under for prime number years, so they don’t come out at the same time and compete for food.
That fucks with my head... maybe there really is a Sky-Fairy who intelligently designed all this shit.
Until he got to mankind - he was pissed and/or hungover that day. -

- cocoon yourself and emerge as a completely different looking creature
- monarchs able to remember where 3 generations ago were born and returning to the same spot
- monarch caterpillars that survive only eating the milkweed plant. That plant is poisonous, and kills many of the caterpillars, but those that survive are left alone by predators, because they carry the milkweed toxin even as butterflies

And the adult butterfly only lives for 60-70 days usually, just enough time to mate then dead!!
