We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.

François "Pierre" Picaud (French: [piko]) was a 19th-century shoemaker in Nîmes, France who may have been the basis for the character of Edmond Dantès in Alexandre Dumas, père's 1844 novel The Count of Monte Cristo.

I always assumed it came from Shakespeare, or something along those lines. That it actually came from putrid legalese was like finding out that my online girlfriend was an AI chatbot all along.

And yes, I learned about it from the popular "casual geographic" tuber. But given my involvement with bears, I also have a soft spot in my heart for raccoons. And this lady (and more importantly this species!) deserve more recognition!

There's only about 250 left in the wild and, despite having tons of available funding, Mexico is not publicly funding any conservation for them.

A Brief History of America’s Private Prison Industry

From FBI reject to private warlord: the rise of George Wackenhut

By 1966, Wackenhut could confidently state that it had secret files on 4 million Americans

Many of the Wackenhut documents and a series on student movements in California highlight the suspected connections between Communism, opposition to the Vietnam War, and the broader left counterculture of the 1960s, and document the right's evolving definition of "subversion."

An ICE Contractor Is Worth Billions. It’s Still Fighting to Pay Detainees as Little as $1 a Day to Work. GEO Group, whose stock is valued at $4 billion, says that state minimum wage laws don’t apply to the cleaning services that it’s asked detained migrants to perform at facilities where they’re kept.

Ice contractor plans for surveillance boom under Trump migrant crackdown: Geo Group, an Ice partner, is moving at ‘unprecedented speed’ to build out its monitoring, executive chair says

Better know a private prison giant: GEO Group’s Board of Directors

Feb 2025: Private Prison Exec Calls Mass Deportation Plans ‘Unprecedented Opportunity’ GEO Group Chairman George Zoley said the company stands to gain up to $1 billion in additional revenue from detaining and surveilling undocumented immigrants.

The man who is making a killing from Trump’s current onslaught of immigrant persecution is himself an immigrant. In fact, if George Zoley had been born just 20 years later, he’d more likely be cowering inside the Aurora Detention Center instead of raking in the profits from it.

George C. Zoley, chairman of the board and founder of GEO Group, the second largest private prison company is the United States, has been with GEO or its former parent company, the Wackenhut Corporation, since 1981. Zoley has called late George Wackenhut, the controversial right-wing founder of Wackenhut Corporation, the person he most admired.

Among the many concerning controversies involving Wackenhut corporations, one that might seem especially relevant in 2026, was their suspected involvement in several murders relating to the very convoluted Inslaw and PROMIS (Prosecutors Management Information System) software scandal of the 1980s. The software was sold as an automation system for police and court data, and advertised as one day having the potential to predict crime before it even happened. It was allegedly stolen and modified before being distributed by the U.S. government and used to spy on other countries.

We know from witness statements that the murders appear to be connected to the corruption surrounding Wackenhut and the PROMIS affair. We know from FBI’s own records that the Bureau looked into the matter. And most recently, we know that the FBI has not only repeatedly refused to release those files, but apparently removed the request from their FOIA tracking system.

 adults more prone to spontaneous false memories than children are. However, children are still more vulnerable to externally induced false memories, like those that stem from leading questions or learning new information after the event.

The National Institute of Child Health and Human Development provides one evidence-based protocol investigators can follow when working with young witnesses.

The author wrote a book about this subject in 2022:

The larvae of the cheese fly (Piophila casei) are deliberately introduced to pecorino cheese, where their digestive action produces an advanced level of fermentation, including a breakdown of the cheese's fats. The cheese's texture softens, and a liquid called làgrima ('teardrop') may seep out.

Source is Chapter Eighteen of Without Precedent: Chief Justice John Marshall and His Times by Joel Richard.

I went in expecting this to be dry, but it's one of the best biographies I've ever read. It's oozing with the faux-cordial schoolgirl drama of the early Republic, including anecdotes like one where Marshall's second cousin and bitter rival Thomas Jefferson missed him for a meeting at his hotel and wrote on a calling card that he was "lucky to find him out" – but then realized his mistake and clumsily corrected it to "UN-lucky". Marshall later remarked that it was only time Jefferson had ever come close to telling the truth.

The book describes Marshall's The Life of George Washington – which he wrote dually as a favor to Bushrod Washington and to pay down his own land debt – as a "glutinous" five-volume, 1000-page advance subscription series whose first volume was delivered two years too late, which starts at Pre-Columbian history but gives scraps for Washingon's early life ("Washington sprang full-grown in volume two and immediately plunged into the Revolutionary War"), and which gives "flat descriptions" of the war which he participated in alongside Washington.

I love this book.

Today I learned that snot turns yellowy greenish for the same reason that pee turns yellow, dehydration. The snot usually isnt yellow other than when we are sick because usually we don't have a runny nose while dehydrated except specifically when we are sick.

And also once again, humidifiers save the day because they both tackle the dehydration by putting moisture into your airways and the nature of water in the air helps break up stuff that is stuck anywhere in your airways by lubing it up and making it take its course faster while also freeing up bandwidth for your body to continue shoving more of the sickness out of your body faster which helps you recover sooner.
