How many of your friends can see all the dots in this optical illusion? Probably none.

Your brain literally won't let you win against this optical illusion:

There are 12 black dots in the picture, but I'd bet good money that you'll never be able to see all of them at once. If I squint, I can get four, and only four.

The illusion started taking over the internet after game developer Will Kerslake shared it via Twitter, but the picture itself originally came from the Facebook page of Akiyoshi Kitaoka, a psychology professor in Kyoto, Japan. It appears to be a variation of Ninio's extinction illusion, which is a grid illusion that scientists use to explain a big scientific concept.


Why you can't see all 12 dots? Basically, we can blame evolution.

The back of our eyes are full of light-sensing nerve cells, all crowded together, waiting for stimulation. You might think that when something interesting happens, they'd all start shouting and firing off signals — a furious rush of noise. But that's not what happens.

Instead, excited nerve cells actually kind of "shush" their neighbor cells, a phenomenon called lateral inhibition. They do this because it helps the message get through — if only a few people are shouting, the signal is clearer.

The end result is that our visual contrast goes up, but at the cost of muting whatever we're not looking at.

Meanwhile, our brain tries to be helpful by filling in that incomplete information with whatever it guesses is there. And since most of this picture is grey lines, our brain just leaves out the black dots.

So you're not going crazy, I promise. There really are 12 dots, but our eyes and brains do weird stuff sometimes to help us focus and survive. And as for what it means if you can see more dots than someone else? Well, the science doesn't really tell us much. Maybe you just have a different level of lateral inhibition than them, or maybe your brain is better at filling in the gaps.

Little mind games like this remind us of the limits of our brains.

We often assume seeing is believing, but optical illusions help show that's not true. Scientists are now using optical illusions to study how we perceive the world, why we react to certain things, and why we make quick assumptions. Optical illusions can teach us about bigger subjects like schizophrenia or even racism!

And, if nothing else, they're kind of trippy and fun.

Pennsylvania home is the entrance to a cave that’s been closed for 70 years

You can only access the cave from the basement of the home and it’s open for business.

This Pennsylvania home is the entrance to a cave.

Have you ever seen something in a movie or online and thought, "That's totally fake," only to find out it's absolutely a real thing? That's sort of how this house in Pennsylvania comes across. It just seems too fantastical to be real, and yet somehow it actually exists.

The home sits between Greencastle and Mercersburg, Pennsylvania, and houses a pretty unique public secret. There's a cave in the basement. Not a man cave or a basement that makes you feel like you're in a cave, but an actual cave that you can't get to unless you go through the house.

Turns out the cave was discovered in the 1830s on the land of John Coffey, according to Uncovering PA, but the story of how it was found is unclear. People would climb down into the cave to explore occasionally until the land was leased about 100 years later and a small structure was built over the cave opening.

Oregon utilizes teen volunteers to run their YouthLine teen crisis hotline

“Each volunteer gets more than 60 hours of training, and master’s level supervisors are constantly on standby in the room.”

Oregon utilizes teen volunteers to man YouthLine teen crisis hotline

Editor's Note: If you are having thoughts about taking your own life, or know of anyone who is in need of help, the 988 Suicide & Crisis Lifeline is a United States-based suicide prevention network of over 200+ crisis centers that provides 24/7 service via a toll-free hotline with the number 9-8-8. It is available to anyone in suicidal crisis or emotional distress.

Mental health is a top-of-mind issue for a lot of people. Thanks to social media and people being more open about their struggles, the stigma surrounding seeking mental health treatment appears to be diminishing. But after the social and emotional interruption of teens due the pandemic, the mental health crises among adolescents seem to have jumped to record numbers.

PBS reports that Oregon is "ranked as the worst state for youth mental illness and access to care." But they're attempting to do something about it with a program that trains teenagers to answer crisis calls from other teens. They aren't alone though, as there's a master's level supervisor at the ready to jump in if the call requires a mental health professional.

The calls coming into the Oregon YouthLine can vary drastically, anywhere from relationship problems to family struggles, all the way to thoughts of self-harm and suicide. Teens manning the phones are provided with 60 hours of training and are taught to recognize when the call needs to be taken over by the adult supervisor.

Buffy Sainte-Marie shares what led to her openly breastfeeding on 'Sesame Street' in 1977

The way she explained to Big Bird what she was doing is still an all-time great example.

"Sesame Street" taught kids about life in addition to letters and numbers.

In 1977, singer-songwriter Buffy Sainte-Marie did something revolutionary: She fed her baby on Sesame Street.

The Indigenous Canadian-Ameican singer-songwriter wasn't doing anything millions of other mothers hadn't done—she was simply feeding her baby. But the fact that she was breastfeeding him was significant since breastfeeding in the United States hit an all-time low in 1971 and was just starting to make a comeback. The fact that she did it openly on a children's television program was even more notable, since "What if children see?" has been a key pearl clutch for people who criticize breastfeeding in public.

But the most remarkable thing about the "Sesame Street" segment was the lovely interchange between Big Bird and Sainte-Marie when he asked her what she was doing.

Mom shares her brutal experience with 'hyperemesis gravidarum' and other moms can relate

Hyperemesis gravidarum is a severe case of morning sickness that can last up until the baby is born and might require medical attention.

@emilyboazman/TikTok

Hyperemesis gravidarum isn't as common as regular morning sickness, but it's much more severe.

Morning sickness is one of the most commonly known and most joked about pregnancy symptoms, second only to peculiar food cravings. While unpleasant, it can often be alleviated to a certain extent with plain foods, plenty of fluids, maybe some ginger—your typical nausea remedies. And usually, it clears up on its own by the 20-week mark. Usually.

But sometimes, it doesn’t. Sometimes moms experience stomach sickness and vomiting, right up until the baby is born, on a much more severe level.

Hyperemesis gravidarum (HG), isn’t as widely talked about as regular morning sickness, but those who go through it are likely to never forget it. Persistent, extreme nausea and vomiting lead to other symptoms like dehydration, fainting, low blood pressure and even jaundice, to name a few.

Emily Boazman, a mom who had HG while pregnant with her third child, showed just how big of an impact it can make in a viral TikTok.

The cast of TLC's "Sister Wives."

Dating is hard for just about anyone. But it gets harder as people age because the dating pool shrinks and older people are more selective. Plus, changes in dating trends, online etiquette and fashion can complicate things as well.

“Sister Wives” star Christine Brown is back in the dating pool after ending her “spiritual union” with polygamist Kody Brown and she needs a little help to get back in the swing of things. Christine and Kody were together for more than 25 years and she shared him with three other women, Janelle, Meri and Robyn.

Janelle and Meri have recently announced they’ve separated from Kody. Christine publicly admitted that things were over with Kody in November 2021.

Finally, someone explains why we all need subtitles

It seems everyone needs subtitles nowadays in order to "hear" the television. This is something that has become more common over the past decade and it's caused people to question if their hearing is going bad or if perhaps actors have gotten lazy with enunciation.

So if you've been wondering if it's just you who needs subtitles in order to watch the latest marathon-worthy show, worry no more. Vox video producer Edward Vega interviewed dialogue editor Austin Olivia Kendrick to get to the bottom of why we can't seem to make out what the actors are saying anymore. It turns out it's technology's fault, and to get to how we got here, Vega and Kendrick took us back in time.

They first explained that way back when movies were first moving from silent film to spoken dialogue, actors had to enunciate and project loudly while speaking directly into a large microphone. If they spoke and moved like actors do today, it would sound almost as if someone were giving a drive-by soliloquy while circling the block. You'd only hear every other sentence or two.
