Structure of pretty much every known protein predicted in a year
https://www.nature.com/articles/d41586-022-02083-2

Researchers used to take years to work out the structure of a protein using x-ray crystallography and this AI does it for 200 million proteins in a year and they can just search it out in the database in a few seconds. The astounding and far reaching nature of this accomplishment cannot be overstated. This is something that was unimaginable five years ago and unfeasible until a year ago.

Was reading that earlier. Very k00l!

Sigh...growing crystals was so much fun.

Betelgeuse blows away a huge piece of its surface.

That’s not reassuring… I assumed the sun was fairly stable, but I guess these things can just blow off giant sections in previously unknown ways?

(Article says it blew it’s top in 2019. Incorrect! It blew it’s top in 1376!)

Mind bottling.

Betelgeuse is 20x more massive than the Sun and 1000x wider (almost a billion miles in diameter ). It's inherently much, much less stable than the sun.

Don’t prop me up while I’m doomscrolling.

You might like this Melvyn Bragg episode where they discuss the death of stars. I have to go back and listen to it again, there were some mindboggling comments made by some of the guests.

Melvyn Bragg and guests discuss the abrupt transformation of stars after shining brightly for millions or billions of years, once they lack the fuel to counter the force of gravity. Those like our own star, the Sun, become red giants, expanding outwards and consuming nearby planets, only to collapse into dense white dwarves. The massive stars, up to fifty times the mass of the Sun, burst into supernovas, visible from Earth in daytime, and become incredibly dense neutron stars or black holes. In these moments of collapse, the intense heat and pressure can create all the known elements to form gases and dust which may eventually combine to form new stars, new planets and, as on Earth, new life.

The image above is of the supernova remnant Cassiopeia A, approximately 10,000 light years away, from a once massive star that died in a supernova explosion that was first seen from Earth in 1690

kinda puts all the political dooming, glooming, and raving in perspective.

Seems like it could be cool science, but I can’t read the article. Maybe one of you can let us know.

New Jupiter pics from JWST are pretty sweet

That’s rad. What’s the glow? Is it back lit from the sun there?

According to another image in the set, it is the aurora. Which may be really bright in IR imagery.

They say it’s the auroras, so technically you could say it’s from the sun

[Supermoon]

So cool

[ötzi]

How come there's so few stars in the background? The thing looks fake. I'm not sayin', I'm just sayin'.

[From_the_NEK]

Because jupiter is relatively close and bright the exposure time was probably pretty short. So only a few of the brightest background stars show up.

Sure that’s the way science WANTS you to think. It’s probably actually aliens blinking out the stars

[PB]

Yeah, those cagey aliens finally had enough of our shenanigans and enclosed the entire solar system in a lattice patterned (hence, some stars still visible) Dyson sphere to keep our contagion from spreading.

Can you blame them?
