This is fuckin huge if it turns out to be a winner. I mean, almost on the level of the discovery of penicillin big. I did 15 years in EMS, and the single biggest problem in Trauma care is the lack of blood substitutes. Once those blood cells leave the body, that's it, they're gone, and either you've got replacement blood or you don't. Artificial blood has been one of the holy grail pursuits of medicine for decades, and we've had many, many dead ends with it. Hopefully they've cracked it.

The artificial blood is created from expired donor blood, so we still have to keep donating blood, but it increases the shelf life from 42 days refrigerated to 2 years at room temp, which is pretty amazing. Studies began in 2022.
Here's what it looks like:

Amazing accomplishment. Though, does anybody else think it looked like somebody mixed some pepto bismal in a blood bag? I find it a little funny.
Oh I think I have seen this one, don't the vampires get to go public now? And we find out werewolves and fairies are real too?
Thinking quickly, Japan constructs a homemade blood from a scientist, a shell and a blood.
Joking aside, I remember articles on artificial blood from 20 years ago, but it always failed in trials. I’m glad to hear things have progressed a good bit.
What’s the microplastic content percentage?
All of the commenters are vampires?
Why not pig blood, then?
We can't make lab hemoglobin yet?
They're getting the hemoglobin from expired donor blood.
So presumably, we can use real blood until it expires and then process the expired blood to extend its usefulness for up to 5 years.
This is already a massive improvement.
Any mammal blood contains hemoglobin. Think about that.
Damn.
They're winning the Nobel for this.
If it works, it will be one of the most deserved ones.
At scale it'd probably be cheapest to just gin up some yeast that produces it. They were probably using expired blood for research purposes because they had easy access
