World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

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.
Thank you for the nuance. Bad data and hyperbole doesn't help what I agreed is a serious issue.
Psypost is like the the Daily Mail of science journalism. Kind of just dismiss everything I see from them at this point. Thank you for the rebuttal.
I don't think this is the kind of neuroplasticity we're supposed to be aiming for.
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's a product from the Oil and Gas industry - a crude oil byproduct, naptha into nurdles - and they make a fucktonne of cash from it. Obviously not talking about every type of plastic or the "bio-plastics." Almost all plastic comes from O&G.
I recall a moment maybe in the early 2000s when the industry lobby tried arguing they were actually being environmentalists and serving the public good by making plastic out of what would otherwise be toxic waste, like they're responsibly using every part of the animal. So ridiculous they dropped the campaign within the week iirc.
But I think about that every time a Premier or Mayor comes out weirdly, strongly opposed to this plastic bag or that plastic straw being banned - that they're virtue signalling to the O&G lobby.
So it's not about what consumers or society embrace, or what's logical or easier. O&G don't care if we recycle it, huff the fumes melting it down, or feed it to the fishes. They don't even really care how little their nurdle sells for, just as long as they can still sell it for something.
Plastic is generally cheaper; for a while there was a misguided push against using paper/cardboard because sAvE tHe TrEeS
The plastic industry is why.
I'm not so sure what cardboard/paper you mean? If you mean something like the paper cups that coffee comes in, they also contain plastic. Dirty paper/cardboard can also not be recycled, so your pizza carton ends up in a landfill or burned. And what do you mean by foil? Genuinely curious.
In my area a lot of takeout places now offer reusable options for a deposit. Usually it is a cardboard with plastic lining container if it is one way. Except the Asian takeout places, they are all over the place from classic black plastic to aluminum containers to styropor to - circling back - the plastic carton stuff.
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?
I don't know if you've heard, but our brains are apparently full of plastic. We need articles like this dumbed down for us.
Yes, it is. Probably a few phrases written by a human and then a summary of the article with AI.
So what? We all have to make a bit of sacrifice to maximize shareholder value. Stop whining about it!

Life in plastic, it's fantastic
Who would have guessed that song was an apocalyptic warning
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
Yup it's quite saucy
A relative bright spot amidst a sea of bad news:
"Bottled water alone can expose people to nearly as many microplastic particles annually as all ingested and inhaled sources combined,” said Brandon Luu, an Internal Medicine Resident at the University of Toronto. “Switching to tap water could reduce this exposure by almost 90%, making it one of the simplest ways to cut down on microplastic intake.”
Dunno if anyone reading this is still drinking bottled water, but, uh, now you have another reason to not do that.
The researchers speculate that microplastics could contribute to neurological conditions by obstructing blood flow, interfering with neural connections, or triggering inflammation in the brain.
A whole generation dumbed down by lead and now microplastics. We fucked
I am longing for plastic-eating bacteria to be released into the wild. There are other materials we can use.
The medical field would be categorically fuct. Just the loss of sterile packaging would have serious consequences. Minimally invasive surgeries, joint replacements, bandages that don't adhere to wounds, stents...
Then let's consider cordage. Mountain climbing, arborists, rescue teams, sailboats (the most efficient way to cross oceans), ships, construction... the loss of just Dyneema/UHMWPE, which is a relatively new entrant to the cordage field would have seriously negative impacts.
There is a lot of energy bound up in those long molecules, and there are no unexploited niches in balanced ecosystems. There are already bacteria that can consume certain polymers under narrow conditions. Humanity is gonna be so screwed for a long time if bacteria can slip those narrow parameters.
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.
There are plastic eating microorganisms, both fungi, and bacteria.
But, they take a long time to break down plastic. I've had a fungus that can digest plastic in a mushroom cultivation bag for nine months and only one specimen has made it through so far.
I imagine splicing the gene that allows for the production of this enzyme into an ocean bound microorganism would clean up a lot of it while not affecting most of our terristrial infrastructure.
Of course, folks put plastic tubing and what not in the ocean too, so I guess we'll all have to die instead.
I would like for you to meet my friend, the oyster mushroom. I'm wondering what level of soil accumulation we need to support massive, city-wide oyster mushroom blooms
Think of how many things around you are made of plastic. What about critical pieces of things like airplanes? What would you replace that with to prevent the bacteria from causing damage to them?
I could probably pick a few things on my desk right now that would be much more difficult and much more costly to produce with other materials.
Yes, I am sure such a bacteria being released at this scale would have absolutely zero negative consequences
Come on asteroid where the fuck are you….
