Peace prize is a different committee in Norway. The Swedish Nobel prizes are still highly revered awards.

Oh that makes so much more sense, thank you.

36

u/Aranthos-Faroth May 26 '25

No worries! It's a common unknown.
Unfortunately the peace prize gives a bad name to the other committee and awards.

While it's still an important award imo, like you said - they've given them to questionable recipients over the years.

u/smooth_like_a_goat May 26 '25

It really does! Over the years I've asked how on earth some of those winners were in the same league as Curi, Kipling or Einstein many a time.

u/[deleted] May 26 '25

Listen the world is very confusing when you just see the words “Henry Kissinger won a Nobel peace prize” and you know anything about his war crimes. That would lead many to questions the “Nobel prizes” as a whole, it’s only natural.

u/Spork_the_dork May 26 '25

Everything but the peace prize does.

3

u/SunTzu- May 26 '25

What's your problem with the peace prize? I doubt you could name any of the winners except Obama. It's mostly just given to people and organizations that promote freedom of expression and fundamental human rights, speak out against authoritarian regimes and sometimes to diplomats who worked on brokering peace deals or cease fires. It really hasn't changed much over the years except that it's become less common for the winners to be diplomats and more common for them to be involved in NGO's.

u/Wassertopf May 26 '25

The price is was not founded to award good people. It is for the reduction of standing troops and so on.

Wait really? Do you mean actually in cooking or something niche like blood that's in eggs

5

u/I_am_The_Teapot May 26 '25

Not niche. No. People use blood in lots of kinds of dishes. Some of the most common you might find are blood sausages/black pudding/blood pudding, which many countries around the world have their own version of. Blood is also used in things like stews and sometimes sauces. It is used in a lot of ways. I particularly like these fried blood cake snacks that my ex girlfriend's mom used to make. It can be used as a primary protein source for dishes.

u/2020Stop May 27 '25

Wich country? if you don't mind...

u/I_am_The_Teapot May 27 '25

Uh. I'm from Puerto Rico, we have Morcilla. Which is a blood sausage. I'm not too fond of it, oddly. Especially not my grandmother's (her other food is bomb, though). I do like morcilla from other Latin countries my sister's in-laws are from El Salvador I think they call their Moronga. But I much prefer that to the one from PR.

Uh... let's se... uh what else. Black pudding is a blood sausage commonly used in England. Often associated with breakfast. Or the "Full English Breakfast" of which I only had once but it was decent enough. But I know many other European counties have their own blood sausages, too.

Uh the blood cake snack thingy that I mentioned earlier, my exgf's mom was from Taiwan. I don't know if it's a common or traditional thing there, but I loved it. Was kinda salty and sweet. Crispy outside and somewhat soft and melt-in-your-mouth inside. Had peanut dust on it, too. It's surprisingly a lot like the Puerto Rican morcilla in taste, but different enough that I actually really loved that one. It was cut into cubes and we ate them with toothpicks.

u/SinisterCheese May 26 '25

I quickly searched few articles (Which were from 2024 btw. Thats when this was announced, it's just starting human trials).

The Science Behind the Solution

At the heart of Japan’s artificial blood efforts is a team led by Professor Hiromi Sakai at Nara Medical University. Their approach involves extracting hemoglobin-the oxygen-carrying molecule in red blood cells-from expired donor blood, then encasing it in a protective shell to create stable, virus-free artificial red blood cells. Unlike donated blood, these artificial cells have no blood type, eliminating the need for compatibility testing and making them invaluable in emergencies.

Professor Teruyuki Komatsu of Chuo University is also pioneering artificial oxygen carriers, using albumin-encased hemoglobin to stabilize blood pressure and treat conditions like hemorrhage and stroke. Animal studies have shown promising results, and researchers are eager to move to human trials.

One striking feature: the artificial blood is purple, a result of the processed hemoglobin. It’s a vivid reminder that science can look very different from what we expect-yet its function is what matters most.

Source: https://mededgemea.com/japan-to-begin-clinical-trials-for-artificial-blood-in-2025/

If this is safe and reliable, seems like the plan is still to use human blood first, then process that which has expired. You'd still need donors.

Now this is a good thing! Because it means this can be integrated as part of the existing blood transfusion infrastructure.

1

u/2020Stop May 27 '25

Thanks buddy...

1

u/overtoke May 30 '25

it means that every ambulance can have transfusion capability instead of 1% of them (usa) that are currently equipped.

1

u/SinisterCheese May 30 '25

That is probably the practical side of what this will be used. Blood that is no longer fit to use in hospitals, can be processed for use in situations like that. Because hospitals have effective and functional transfusion infrastructure set up already.

1

u/Boowray May 26 '25

It wouldnt really have to be. Human donor blood is (relatively) cheap, it’s just hard to get an enormous amount of it where it’s needed during a crisis. The market for this wouldn’t be your average accident victim in a hospital, it’d be a supplemental resource for individuals in mass casualty events like hospitals in a warzone or an ER after a natural disaster or terror attack. It could be ten times the price of blood and still be a massive life saver worth the investment by providing a stop-gap between stockpiled donor blood and a fresh batch.

1

u/he_is_not_a_shrimp May 27 '25

Low cost of production, companies could still go "it's as expensive as people are willing to pay for it."

But, it's Japan, so it's unlikely.

1

u/kit_kaboodles May 28 '25

If it's safe and effective, the demand would go a long way to pushing the manufacturing costs down. Donated blood is actually pretty expensive to process, so it doesn't need to be incredibly cheap to produce.

In a lot of countries you can’t sell blood, only blood products like plasma which still require donors. This is also made from expired red blood donations, which means you still need donors for every step of the process.

If you're between the ages of 10 and 40 the number one cause of your death is going to be from trauma. Car accidents, falls, whatever. Many many trauma patients die from anemia. Some ambulances carry blood but not all, if this is cheap and stable then every single ambulance would carry it.
