This is something fun I just came across. It looks like scientists have figured out a way to use beer to recycle metal waste!
Well, not exactly beer but more of a beer by-product.
The TL:DR is that austrian researchers have discovered that spent Brewers Yeastcan be used to repeatedly draw out metal waste, like aluminium, zinc and copper.
Apparently, the same byproduct is also used to make Vegemite which is a popular Australian food spread and Marmite a popular British food spread). I have never heard of any but oh well.
According to their claims, this beer byproduct can pull 50% of the copper and 90% of the zinc that was present out of the water. Furthermore, the yeast can supposedly be reused and recycled.
Now, chemistry isn't my strong hand so here's a quote of how the method works:
Electrostatic interactions on the surface of the yeast allow metal ions to stick to that surface — a process called adsorption. Changing the pH of this solution alters the interactions, which can allow the yeast to adsorb more or different metal ions, depending on the contents of the solution and the specific pH.
Here's a link to the paper if you would like to read more on this research. And here's a link to the press release for a more dumbed down version.
Well, since this is a "sciency" post here are some more cool shit I stumbled upon today!
Like this newly discovered species of rosy-colored deep-sea worm 30 miles (50 kilometers) off the Pacific coast of Costa Rica:
The worm was scientifically described as Pectinereis strickrotti and it's a type of ragworm (Nereididae). It was first sighted in 2009 in a methane seep at a depth of 1000 m. But it was thanks to another expedition in 2019, when the same team managed to acquire samples to describe it as a total new species. Here's a video of the creature in action:
Here's a link to the paper describing the species if you would like to learn more about the critter.
In other news, scientists are one step closer to the closest thing we can get to a real life Jurassic Park. Unfortunately, I am not talking about dinosaurs but another cool extinct animal. The Mammoth!
Scientists at the company Colossal Biosciences have developed induced pluripotent stem cells from elephants, an important first before doing the same (if ever) with mammoth cells from preserved tissues.
Will we ever see a live mammoth? Dunno, there is still a long long way to go but it's cool to know there are peeps working on cool shit like this :)

Ok I have a last treat for you!
Can you guess what that is?
It's a a hammerhead shark (Sphyrna tiburo) embryo! Cute 😍
The image is taken from this very interesting article, you may want to check it out. It has all kinds of cute embryo sharks :p
Ok, I think I gave you enough interesting material to read and digest. Funny how I started with just a beer related post 😁
Cheers 🍺

Vegemite is straight gross, and I know any Aussies reading this will forever hate me for that, but it's true. I tried it once while travelling in Vietnam of all places, met an aussie guy who literally wouldn't leave home without it and he made me try some, it's disgusting. The metal extraction through adsorption on used brewer yeast is fascinating though. And those lil baby hammerhead embryos are adorable
Whatever, Leaflander 😝
😂😘
Lol, sounds like shit. I'll stay away!
Honestly good call, you're not missing anything, the stuff is nasty.
Sounds like a a waste of beer byproduct. Real men drink beer and drink the byproduct. Therefore, Austrians are gae
Real men drink piss
Your title says Austrian*
Id say they are Austrians alright
Dang, they are confusing us by working with Australian stuff!
Lol

All you need to know is that Vegemite is fucking delicious.
Can I use it as anal lubricant though?
It can be used for anything.
Mammoths ehhh
So we'd prolly get to see this guy 😀
😂😂
Shark embryos are cute for sure!! But the future of recycling is indeed microorganisms hehe

Interesting use of the by-product of beer
Like you I am not an expert in chemistry and I prefer to drink !BEER when I eat !PIZZA :) but I have a chemistry sister and I turned this post over to her because she might be interested

Thanks for all those tips! Whats the discovery thing?
That is an interesting use of a beer byproduct.
As for that worm, I wouldn't have expected it to be on. It's weird.
That bonus image I think is something like a eel.
Vegemite and Marmite are nasty. You're not missing anything. 😆

Uufff!
When I eat this a weight goes off my shoulders! 😂😂😂
Lol, why?
Vegemite is so disgustingly gross. I’m surprised it doesn’t kill people who eat it.
Lol!
I think I love this strategy

What a nice discovery! I'm glad to learn about it. What are not taught this is our chemistry class.🤣
Wow, this is an interesting discovery, using of beer byproduct to tackle metal waste. Thanks for sharing.
Aside from the recycling part of the story, that picture instantly made me gross out because of our friend showing ups Marmite. We were curious what it tastes like and she let us smell it first and then taste a tiny bit. It's absolutely GROSS lol. Never ever eating that again :)
But !PIMP the recycling part of your post either way :p
You must be killin' it out here!
@thisismylife just slapped you with 5.000 PIMP, @trumpman.
You earned 5.000 PIMP for the strong hand.
They're getting a workout and slapped 2/3 possible people today.
