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.

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.

[–] [email protected] 5 points 1 day ago

Yes, it is. Probably a few phrases written by a human and then a summary of the article with AI.

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

[–] [email protected] 2 points 19 hours ago

Not reusing words isn't the same as not repeating itself. Especially if it's been given a minimum word count, it will often restate the same information in different ways to fill space.

Of course, this can happen with actual writers as well. That's why editors used to exist.

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.

This is a fine example of AI not being allowed to commonly re-use words, so it tends to use somewhat less common words

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.
