Scientists issue dire warning: Microplastic accumulation in human brains escalating
-
I think that's mostly an issue in America. Here in Europe you can always drink tap water.
We need to immediately research if people in maga areas are the ones who can't drink the tap water

Yes but to a much lesser extent. The act of merely breaking the seal on the cap injects a lot of plastic into the liquid, so skipping that has to count for something
Honestly, I'm not saying that you're lying but that's very hard to accept as truth. Would you have a good source for learning about all this?

Plastic sealed brain is better protected?
Brain has plasticity (changes). Just my little joke.

I don't think this is the kind of neuroplasticity we're supposed to be aiming for.

Attach your brain to a 3D printer. Make some use of all that plastic and print your thoughts. /j

Was this writen by AI?
The researchers found surprisingly high levels of microplastics in the brain tissue. The concentration of plastics in the brain was much greater than that found in the liver or kidney samples. It was also higher than levels previously reported in placentas and testes. The median amount of total plastics for 2024 brain samples was 4917 micrograms per gram, and for 2016 samples, it was 3345 micrograms per gram. For comparison, the 2024 liver and kidney samples were 433 and 404 micrograms per gram, respectively.
Even more concerning was the finding that the amount of plastic in the brain was increasing over time. Brain tissue samples from 2024 had significantly higher levels of microplastics than samples from 2016, representing an approximate 50% increase in just eight years.
Isn't that the same information just repeated after each other?
To measure the microplastics, the researchers first chemically dissolved the tissue. This created a liquid mixture. They then spun this mixture at very high speeds in a machine called a centrifuge. This process separated out any undissolved materials, including plastics, into a small pellet. Next, they heated this pellet to a very high temperature (600 degrees Celsius), a process that breaks down the plastic.
Why does this sound like somebody explaining this to a 10 year old?
Yes, it is. Probably a few phrases written by a human and then a summary of the article with AI.

Scary. Is plastic more or less expensive than cardboard/paper? I'm not sure if it's where I live, but I've noticed that during my childhood, (example) most takeout containers would be either foil or paper. Now, most of them are plastic, even the cups that contain sauces. I don't get why plastic has been embraced so much when the alternatives were far easier to recycle.
Plastic is generally cheaper; for a while there was a misguided push against using paper/cardboard because sAvE tHe TrEeS

AI is actually known to not repeat itself. This is also why it tends to use rare/unusual words since it cannot use the same words repeatedly. Not saying this isn't AI, but repetitiveness is not really an AI trait
Known not to repeat itself? You should listen HFY stories.
Just recently listened to one that referred to the gas giant outside several times and the alien chick’s long ears giving away that she’s an alien many times. We get it! Don’t need to introduce her more than once. Jesus.
EDIT: If anyone is interested in the one I was referring to specifically, here you go:

You're right, I misremembered It's not just about breaking the seal on the cap, the mere friction of the cap on the bottle adds the bulk of microplastics found within
I was thinking of an article from years ago where they were talking about macro plastics nearly visible to the eye getting into the liquid from breaking the seal. Can't seem to find it now though

Thanks that's very useful and good to know.

The original paper about microplastics in the brain seems to have a serious methodological flaw that undermines the conclusion that our brains are swimming in microplastics.
“False positives of microplastics are common to almost all methods of detecting them,” Jones says. “This is quite a serious issue in microplastics work.”
Brain tissue contains a large amount of lipids, some of which have similar mass spectra as the plastic polyethylene, Wagner says. “Most of the presumed plastic they found is polyethylene, which to me really indicates that they didn’t really clean up their samples properly.” Jones says he shares these concerns.
This is from other microplastics researchers. See this article. So before we panic about this, let’s wait for some independent replication and more agreement in the scientific community.
Microplastics are a serious concern, and we need to deal with plastic pollution. Let’s just stick to high quality science while we do that.

Plastic also has the benefit that it's really easy to make in whatever shape with injection molding, and is totally permanent, which if you don't care about disposal is great.
Meanwhile, making stuff out of a sheet of paper is a manufacturing challenge that has resulted in creative solutions like corrugation, and the container might seep through or soften or something.
There's a thing called extended producer responsibility which basically is the idea of making disposal not free anymore for the manufacturer.

I've definitely seen AI get into loops personally. From what you're saying it sounds like they've added restrictions on reusing words to try and solve that.

I am longing for plastic-eating bacteria to be released into the wild. There are other materials we can use.
Like what? If you're building an airplane or a sewer main all substitutes are inferior. The problem is that we're using the ultra-permanent wonder material for, like, candy wrappers.

So is it possible the blood-brain barrier is designed to trap nanoparticles? They do exist in nature.

permenent? can't plastic get melted down and recycled again?
once i put some plastic container in the dishwasher and it got too hot, it kind of melted a bit. it didn't totally melt but the lid doesn't fit anymore.
i dunno if it was injection molded though

Regular boiling is pretty good! The micrplastics end up sticking to the calcium deposits left behind. Never been so happy for that stupid white buildup in my kettle!
"As reported in ACS’ Environmental Science & Technology Letters, boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present."

Fuck, that's good news.
Kinda funny that the tried and true 'works good enough' method of boiling water to cleanse it also works for micro plastics.

You have to remember that plastic containers aren't washed before they are filled with product. That's often where much of the micro/nano plastics come from.
Do you have a source on that? I find it hard to believe we put water into unsanitized bottles.

PVC fell out of use in the 2000s, most buildings use PEX now; but I don't know how that compares.
I believe I've heard that PEX actually breaks down and starts leeching chemicals into the water faster than PVC. It's also a cheaper material. Most of the houses I'm familiar with are still installing PVC.

On the contrary, who didn't?
Let me share with you unique kind of emotions:)
(I mean this in good faith)non-native English speakers. It's actually a distinct source of getting astonished: grow up with some English songs around, love them for their melody and whatnot, then learn some English, then actually listen to or read the lyrics, and... oh, damn. So many things come out in totally different light
