> Fish immune systems sole reason for being is to stop parasites from being present in the meat while the fish is alive.

Ah, good news for you then! Fish immune system most definitely does NOT stop parasites. Every (and I mean it, every) salmon you've ever eaten had some parts of parasites in them.

That's also why you absolutely should NOT eat fresh-caught salmon without thoroughly cooking it. Industrially-caught salmon is always frozen, and it kills parasites.

These fish grew large enough for humans to eye as food, because parasites were effectively limited by the immune system from devouring the entire fish. It's not perfectly effective, but it doesn't need to be.

Thank you for the point about “ingredient stuffing”. I had never considered this method of deceiving consumers and will be on the lookout for it.

Why doesn’t the FDA require explicit percentages be listed..?

In other countries, they do.

In the US, the invisible hand of the market will surely push a food producer to regulate itself effectively.

Never done it, never gonna.

Thank _Neoshade_'s legendary story in a Reddit comment for that - https://www.reddit.com/r/todayilearned/comments/dv99nf/til_t...

With a side helping of Neal Stephenson's Cryptonomicon, and the submarine / treasure hunting arc which describes decompression sickness.

"Fermented Salmon" sounds funny and relatively accurate to me. Why do you call it a tumor? Are the cells cancerous?

Multicellular life naturally exists in a well-ordered matrix according to a rough plan, not a blob in a petri dish, and when it deviates too much from that plan we have various pejorative words for it and feel various health consequences as a result of disordered growths.

Tissue culture in general is more like cancer than not like cancer, even when using "non-cancerous" cell lines. But cancerous and "immortalized" cell lines are particularly useful in cell culture because they don't snuff themselves out. https://en.wikipedia.org/wiki/Immortalised_cell_line

I somehow thought that pure oxygen was poisonous[1], and it needed to be a nitrogen mix. I mean, I guess this stunt demonstrates that I'm clearly mistaken, or that the nuance is in the pressures involed?

1: https://en.wikipedia.org/wiki/Oxygen_toxicity

mapt · 6 days ago
Oxygen weathering is a primary constraint on life on Earth, and every carbon-hydrogen based organism in the past 2.5 billion years has had to develop biochemical coping mechanisms for this toxic gas that wants to react with carbon and with hydrogen; It is harnessing this reaction ("respiration") with biologically mediated processes and modulating it to specific rates that permits us life.

For humans, acute breathing gas toxicity only happens in a high pressure environment.

Air approximates an 80/20 nitrogen-oxygen mix. Atmospheric pressure is 14.7psi.

The 120psi air compressor in your auto body shop is equivalent to a dive only 81 meters deep. SCUBA divers and later saturation divers have probed the various limits of the human cardiopulmonary system using very specialized gas blends all the way down to 700 meters. Too much oxygen partial pressure causes all the symptoms you see listed, and higher partial pressures cause symptoms to appear faster.

> The curves show typical decrement in lung vital capacity when breathing oxygen. Lambertsen concluded in 1987 that 0.5 bar (50 kPa) could be tolerated indefinitely.

This means you could breath 80/20 nitrox at 2.5 bar, or 37 psi, or 25 meters depth, "indefinitely" in the sense of hours or days.

PS: Chronic use of 100% oxygen at atmospheric pressure causes other types of toxicity. Some of the oxidative damage therein, accumulated over the years at a normal 20%, probably directly analogizes parts of the human aging process. Other types of oxidative damage probably work faster than proportional exposure. We only start to notice damage like this in people with impaired lung function who rely on an artificial supply of oxygen boosted to beyond an 80/20 ratio, to breath.

> Hogan (Thiel) vs Gawker and Sandy Hook vs Alex Jones provided a blueprint to weaponize defamation law for political change

Sandy Hook v Jones was not "political". It was deeply, profoundly personal.

The Gawker lawsuit was also about settling personal scores. Obviously Hogan wasn't as sympathetic of a plaintiff as the Sandy Hook parents. But it was more odious because Thiel wanted to punish Gawker simply for hurting his feelings, not lying about him.

> So all we need now is an angry left-wing billionaire

Is there such a thing?

mapt · 6 days ago
Perhaps if there was, we wouldn't need to have this conversation.

The closest we've got is the zombie husk of liberal George Soros, who is a center-left finance bro from a Holocaust survivor family who isn't fond of authoritarianism. While a constantly mentioned specter of the right (the fact that he's Jewish and talks with a foreign accent factors, for paleoconservatives), and probably the largest single donor to Democratic causes...

He isn't actually particularly left-wing, and his work isn't remotely comparable in scope or in aggression to the ideological warfare waged by the Koch Brothers, or the dozens of other billionaires who have joined hand in hand to establish the durable top-down political infrastructure of the GOP. If a politician or pundit just plays along with these people, if you stay loyal to the cause even in the most tortured argument, you will be a made man. There are thousands of positions held open at endowed economics departments, think tanks, lobbying firms, and captive media to reward people who fight the good fight for the right. Lose an election? There is always the possibility of another campaign in another district. Conversely there is a constant threat of well-funded primary campaigns against anyone who doesn't toe the line and kiss the ring.

The Democrats have no such leverage. Their operational interests conflict with the interests of their political base. They mostly seem to come into politics poisoned by Mr Smith Goes to Washington, or The West Wing, and then the people who survive are the ones with more ambition than ideology who do whatever they need to do to ensure incumbency. Their institutional infrastructure seems to be ~five lobbying firms whose only apparent purpose is punching left when their base comes into conflict with corporate donors, and skimming off the top. The only time you will see money weaponized in a meaningful way is to fight against a primary challenge from the left, to include running independents against the primary winner in eg NYC's 2025 mayoral. So goes the "big tent" party.

But if by chance an angry left-wing billionaire spontaneously occurred (let's say the Trump vs Musk relationship went down a little differently)... There are tortious weapons sitting on the table unused, which could be put into effect dismantling this flavor of "journalism". As long as red America is being fed cradle-to-grave, violently ethnonationalist propaganda we're going to have a tough time persuading them out of their worldview.

> Fox news is not, and never has been, intended as satire

Their homepage right now is featuring a pull up and push up contest between Hegseth and RFK jr.

It hardly appears as though they’re trying to be a legitimate news network. (Same goes for CNN - both are incredibly and undeniably outrageous in their reporting)

But I agree, their audiences take their reporting seriously, even if they themselves are just saying what they say for the ratings.

mapt · 6 days ago
A light comedy piece or a plucky human interest story do not erase the statements of fact made or the repeated insistence on being taken seriously which pervade the rest of this institution. It isn't even reliant on their audience taking them seriously, it's reliant on the intended tone and how a reasonable person would perceive that intent.

You can argue that Fox News is intended to be basically the Colbert Report satirizing a certain mindset, but it's an obviously bad-faith argument. The Colbert Report was literally created to satirize the seriousness and mendacity of Fox News and its attempts to persuade people into a set of not just interpretations of the world, but factual beliefs about that world.

There is a line, and Fox runs way over the line into defamatory content multiple times an hour.

I can't immunize myself from currency counterfeiting charges by claiming that I never thought the copies were real, that it was all just in fun, that I was pranking the businesses I spent them at, and that my Youtube channel includes other fun bits of me deceiving people and telling jokes. The one does not exculpate the other.

Looking beyond just eating the output, encouraging research into bioreactors and effective sterilization is a great path towards lab grown organs for humans. Imagine a world where getting a heart transplant isn't a lottery anymore. This is a worthy path for research imho.

Imagine a world where you have to take whatever "heart" a pioneering lab can produce for under $100. Are you gonna be in the first group of recipients to risk it, knowing that these labs are largely unregulated startups?

I can cherish the research path and value the intended endpoint, but knowing what I know of agribusiness, early approval to market seems a mite reckless. Particularly in 2025. Particularly with "sushi-grade fish".

We produce millions of tons of affordable meat from industrial production of animals THAT HAVE immune systems, swimming in antibiotics, that the FDA tells you to cook thoroughly because it's definitely full of salmonella. We chop it up using child labor on production lines that would make you a vegetarian if you saw them.

Don't worry, if you catch any disease you can use any antibiotic that still works after spraying farmed salmon willy-nilly for years.

Antibiotics only work on live bacteria, and only sometimes. "Any disease" is a much broader category.
