Evidence for branched feathers has been established in pterosaurs
The statistically most likely result (Fig. 3 and Supplementary Table 3; highest log-likelihood value) shows that the avemetatarsalian ancestors of dinosaurs and pterosaurs possessed integumentary filaments, with the highest likelihood of possessing monofilaments; tufts of filaments (especially brush-type filaments) are less likely ancestral states.
Bad news, ring fans, Saturn's rings are going to vanish in a mere 300 million years. Better get your ring appreciation in now while you still have the chance.

And that gives me a strong urge to take an oversized sword to it. Looks straight out of Monster Hunter like that.
It's probably an optical illusion or some zoom fuckery (or it's fake) but yes, Saturn is not that much larger from the moon than it is from Earth. Saturn might appear that large if you were past the orbit of Jupiter. Maybe.

That's not how big Saturn would look from the moon, no. But it's how it looks when you look at Saturn through a telescope on Earth with the moon in the foreground. The reason the sizes aren't lining up in your brain is that we don't have an intuitive grasp for how big things look through telescopes. That's why predicting the angular diameter of objects through various lenses requires trigonometry instead of simple arithmetic.
To crunch the composition of this photo down to a human scale, imagine that you're standing at one end of a football field with a bowling ball five yards in front of you and a beach ball at the other end of the field. From here, the bowling ball looks much larger than the beach ball. If someone wrote a message on both balls in a clear 20-point font, you could just about read the message on the bowling ball, but definitely not the beach ball.
If you got a good pair of binoculars and got down on the ground, you could focus on the beach ball in such a way that it filled most of the view and you could read the message. If the top of the bowling ball was in the frame, it would appear huge, many times larger than your field of view.
If you walked forward five yards and tried to recreate the view of the bowling ball you saw through the binoculars, you probably could, providing your nose isn't too big. But if you did that, you'd notice that the beach ball appears much smaller than it did through the binoculars, and you definitely couldn't read the message written on it.
So while you can take a picture of Saturn apparently rising over the horizon of the moon with a pretty simple telescope and camera setup, you couldn't recreate the same photo by taking a picture of Saturn with a regular camera close to the moon.

Hot water heaters: you know how the temperatures are supposed to be kept high to kill bacteria? Turns out we made millions of tiny hot spring habitats for happy little extremophiles Over a third of water heaters tested were positive in one way or another for Thermus scotoductus, a thermophile naturally found in hot springs. A few other thermophiles were detected as well. Those water tanks are kept at temperatures they prefer, and it's all full of nutrients and lacking in competition for them.
They're probably harmless to us; our body temperatures are too cold for them. Probably.
Modern biology would be a hell of a lot slower without thermophilic bacteria. PCR, the process used to amplify selected fragments of DNA, used to require the scientist to add more polymerase (the DNA replicating enzyme) after each step, because the very temperatures needed for PCR to work destroyed the polymerase after each cycle. When a heat-stable enzyme was isolated from Thermus aquaticus, it enabled PCR to be performed with a single dose of enzyme, freeing up enormous amounts of time that scientists could then better spend drinking coffee and sweating over grant applications.

My dad started his undergrad education on a ton of math and physics and chemistry classes. Then he got to biochemistry and regarded it as basically cheating because of all the stuff that doesn't really seem possible.

What really blows my mind is how quickly we went from the invention of heat-stable polymerase chain reactions to the magical bullshit we now use for rapid sequencing.

The further I get into my stem career the more I realize that a great many fields are waiting for a small breakthrough in an adjacent field in order to progress. The electrical engineering world where I play is pretty much waiting for an improvement from the material science guys giving us a much better battery/portable source of electricity. Robotics would immediately take off in a way that would make our current rapid advances look like nothing.

I can't stand this meat prison much longer please put me in a robot body
or maybe the internet
would a consciousness be able to withstand a separation of that magnitude, or would I fragment into an infinite number of pieces, spread across the virtual vastness?
no, you'd still be in your meat prison, you'd just either have your meat senses replaced with a neural connection to a web browser, or a digital simulation copy of your brain would be made and the meat-prison version of you wouldn't get shit

Saturn's gonna be available in 300 million years...
That's... actually longer than I thought was the last estimate which was more like ten thousand years.
tbf that was from I think the 2001 A Space Odyssey novel.
it can't run fast
but this planet
is made of gas

Maybe from one of Saturn's moons

unless you believe in souls and transmigration and that sort of thing I guess, literal ghosts in the shell instead of figurative ones
On the one hand, being able to transfer consciousness would be rad.
On the other hand, it would mean you could delete somebody's mind
