You learn something new every day. And you don't even have to attend a class to do so. You might learn something by accident, through a friend, in a book or on the internet. It could be a recipe, a new route to work, a word you never knew before, a fun fact, or a complex skill. We can keep learning throughout our lives. And as we do, our brain grows. It's a process called brain plasticity. But in order for that growth to occur, we have to exercise and train our brain. As if it were a muscle.
The Today I Learned community has 38 million members. It's a mind gym for anyone obsessed with gaining more knowledge about the world around them. Every day, people post the most interesting and intriguing facts they happened to stumble across. Bored Panda has gathered our personal favorites. From a student who got full marks for handing in a blank essay, to some lesser known truths about famous people, there's bound to be something here that you might want to share at the dinner table tonight. Don't forget to upvote your favorites, and let us know what you learned today.

L Ron Hubbards Grandson is a renowned Slam Poet and activist against Scientology.
In 2019, Eimi Haga handed a blank piece of paper to her professor and hoped for the best. The first year student had been asked to write an essay about a visit to the Ninja Museum of Igaryu. She was studying ninja history. Something she became hooked on after watching an animated TV show as a child.
The night before her essay was due, the 19-year-old spent hours soaking soy beans, crushing them and squeezing them in a cloth. Haga then took another two hours to mix the soybean extract with the right amount of water. Only after she had finished all of this, did she quickly jot down her essay, without giving much thought to the content.

In 2019 a Japanese University student studying ninja history turned in an essay written in invisible ink. The words only became visible when the paper was heated over a gas stove. Her professor without even revealing the whole essay gave her an A.

After a boy in the 1930s found what looked like a "great lump of coal", his family used it as a doorstop for a decade until his dad had "a little look at it." This led to the realization it was the world's largest black sapphire. After being faceted, the Black Star of Queensland is 733 carats.

“I wasn't really worried about getting a bad score for my essay,” Haga later told the BBC. It might seem like the student was cooking instead of paying attention to her homework. But that couldn’t be further from the truth. She’d managed to pull off the ultimate student ninja move, using a technique known as "aburidashi".
The essay was written in invisible ink, and the words only appeared when the paper was heated. Before handing it to her professor, she left a note in normal ink telling him to heat the paper. "When the professor said in class that he would give a high mark for creativity, I decided that I would make my essay stand out from others," she said.

Still happens today... any name sounding "non-white" seems to get automatically chucked in the 'we'll look at that later' bin unless the role is specifically for that population (East Asian character: "Okay, we will look at East Asian names) Even worse with Voice Acting... I have quite literally zero Non-North American accent (I can't speak any Asian languages, at all) - yet... I've heard more than one casting director/assistant say "Yeah, we just heard a bit of... something..." Or... how my demos got a 500% increase in 'listened to' count within days of me changing my profile name to a 'stage name'. Or how I get shortlisted for LOTS of stuff... but they see my picture and... oh, gosh darnit, wouldn't you know, you're not quite right for this (Yes, I know lots of people experience this, it's just a little 'convenient' feeling).

Japanese war criminal Hitoshi Imamura, believing that his sentence of 10 years imprisonment was too light, built a replica prison in his garden where he stayed until his death in 1968.
Her creativity paid off, earning her 100% without the professor even reading all of the essay. "I didn't hesitate to give the report full marks - even though I didn't read it to the very end because I thought I should leave some part of the paper unheated, in case the media would somehow find this and take a picture," said her professor, Yuji Yamada.
The student made world headlines with her magical essay, and put handwriting in the spotlight again. Her ninja move was so intriguing that she was featured on the "Today I Learned" subreddit.

Whether we write or type, we have to use our hands to get words to appear on a page. But because handwriting is more complex, it supports learning more. A study published earlier this year found that “the precisely controlled hand movements when using a pen contribute extensively to the brain’s connectivity patterns that promote learning.”
Psychologist and co-author of the study Audrey van der Meer explained that handwriting is worlds apart from typing. "We don't see that [synchronized activity] in typewriting at all." She added that writing by hand is a "neurobiologically richer process" and that this in itself has cognitive benefits.

Tolkien and CS Lewis hated Disney, with Tolkien branding Walt's movies as “disgusting” and “hopelessly corrupted” and calling him a "cheat"

They hated that it was slapstick, low brow, and cutesying fairy tales. They loved the use of shadow, the movement of the animals, the actual talent behind it all, and that the scary bits were aptly scary; but thought that the cutesying of mythological creatures and adapting fairy stories without telling the entirety of their complex narrative was abhorrent.

Just 2 months after 9/11, another commercial airliner, American Airlines Flight 587, crashed into a NYC neighborhood in Queens after a critical mechanical/piloting failure just minutes after take off. 265 people were killed and several homes were completely destroyed.
Cognitive neuroscientist Marieke Longcamp agrees, saying that handwriting is one of the most complex motor skills our brains are capable of. While van der Meer adds that when you type something, you're not actually processing all the information the way you would when you write it down by hand.
You might think taking notes by hand in a meeting or class is tedious, and time-consuming. But that's exactly why it works. Van der Meer explains that because it takes longer, you're forced to process the information. You might write key words or phrases and use drawings or arrows to work through ideas. "You make the information your own," she told NPR, and that helps it stick in the brain.

Iceberg Lettuce has a water content of 96%. This results in it having essentially no nutritional value and only trace amounts of vitamins and minerals.

Many vegetables and fruits have very high water content. For lettuces, the vitamins are in the dark leaves; iceberg has very little dark green thus, low in vitamins; still it has a decent amount of Vitamin A, Vitamin K, and folate. It's a place to start to get someone who doesn't want to eat vegetables to give something a try.

Medieval European cuisine used to be more complex and flavorful. However, once spice became cheap and readily available to the poor, the elites started taking spices out of European cooking as they didn't want to be associated with the poor. This trend had lasting effects on European cuisine.

Europeans originally went looking for spices to make rotten food tolerable. It makes sense that serving bland food would show you can afford fresh ingredients

Senior citizen Emerich Juettner eluded the US Secret Service for 10 years while he used just enough poorly created counterfeit $1 bills (one version misspelled Washington) to support himself & his dog. He only used fake $1 bills one at a time & never to the same place twice. He'd serve 4 months.
Stephanie Did It 2 months ago
Per Wikipedia, he only used his funny money a dollar at a time, and never in the same place twice so that his victims never suffered the loss of more than a dollar. Hence, Juettner was sentenced to one year and one day in prison, plus a one-dollar fine that elicited laughter from those inside the courtroom. No mention is made of his serving only 4 months of his sentence, at least from that source.

George Washington was unusually tall (6'2") and quite strong, and never wore a powdered wig.
Tabitha 2 months ago
The tall gene ran in his family and he had the benefit of being rich and eating a healthy diet. My Slovene grandparents came to the US in 1909-1910. They were both barely 5 feet tall (grandma was about 4’10” and grandpa was around 5’2”). Their son, my father, ended up being 6 feet 1 inch tall, and their daughter, my aunt, was 5 feet 6 inches tall (tall for a woman in the 1930s). The tall gene was always there, but it just wasn’t being fed while my grandparents were living as Eastern European peasants back when Slovenia was part of Austria-Hungary under the Hapsburgs monarchy.

Is this about Myxo? Just checked OP, yeah, it's Myxo. Myxomatosis, a natural mild illness of the Brazilian and Brush rabbits of the Americas, it was widely used as a biological European rabbit control in the 1950s, to devastating results. It's very widely studied because of this. Because it can be spread by contact and by fleas, an infected rabbit can spread it across, well, a whole country, hundreds of millions of rabbits. In places where it was released (or spread to, rabbits don't follow country borders), over 90% population death occurred, and the survivors are all immune to it - and also carriers, which is why in countries with Myxo, you shouldn't mix wild rabbits and domestic rabbits (domestic rabbits are domesticated European rabbits and they will suffer immensely before dying). Erm...another thing that I did a paper on after seeing some sick rabbits in a rescue centre, they were mixing wild and domestic rabbits in the same enclosure.

Costa Concordia, the cruise ship that sank in 2012, resulting in the death of 32 people, had been carrying a large amount of mafia-owned cocaine when it sank and traces of it were found in Captain Francesco Schettino's hair samples.
Kira Okah 2 months ago
Likely knowledge of the d***s was not known to the captain, or any of the senior officers, but it would have taken the complicity of at least one crew member. The particular mafia group that hid the d***s aboard is known for hiding d***s aboard cruise ships without senior officer knowledge. Note: traces in hair samples /= traces in the hair strands themselves - the strands and his urine tested negative, n evidence that he had taken any d***s.

Hippos can defecate into rivers so much that their feces builds up and kills fish through hypoxia, or lack of oxygen. In the Mara River, about 4,000 hippos poop out more than 9 tons of dung each day. Hippo feces also leaves behind chemicals such as ammonium and sulfide, which is harmful to fish.
