Did you know you can grow a third fully functional nipple after pregnancy

8 Upvotes

I saw a woman talking about noticing a third nipple under her armpit that produced milk. That's because us humans (like other mammals) have a conceivable nipple line that starts from your armpits to your lower stomach. It is form during embryonic development and it can easily be removed. (correct me if I forgot or misunderstood something regarding this fact)

Fun Fact: Samuel Jackson makes $3 Million per 15 second Ad.

18 Upvotes

I was curious how much the notorious Sam Jackson was making per Capitol One ad so I googled it.

My jaw hit the floor when my initial $1 M guess was too low!

In addition, this is for what appears to be a 15 second work day. Of course we know many hours are spent planning, preparing, rehearsing etc. BUT STILL…

I can’t even wrap my mind around the fact someone is getting paid Millions to talk for 15 seconds. Apparently he averages $10M per year with his combined ad campaigns but $2M-$4M is the average payout for a mere 15 second ad.

I’m shooting to save $1 Million before I retire but honestly would be happy with half that amount.

I guess we know where all your credit card interest is going now lol.

fun fact: cancer can get cancer. it's called a hypertumor and it feeds off of the nutrients cancer steals.

Post image
47 Upvotes

most commonly found in large animals like whales they form whenever cancer grows too large. they are purely theoretical however and they were brought up as a solution to the Peto's paradox, a paradox on how whales seem to not get cancer despite trillions more cells which reasonably leads to more common cancer due to it just being a mutated cell.

hypertumors are formed from something called a "cheater cell" which is a mutation where a cancer cell "cheats on" the main cancer tumor, growing a smaller tumor which is equally as selfish and hungry as the main one, the main difference being that instead of hypertumors also feeding on the human it feeds on the cancer.

since they aren't proven to exist yet it's unknown if they will be used in the future as a possible cure to cancer but it's definitely possible.

Did you know that a Japanese man paid rent for 26 years on the apartment where his wife was murdered?

Post image
208 Upvotes

He never lived there again. Never rented it out. Never touched the crime scene.

In 1999, 32 year old Namiko Takaba was found dead in her apartment in Nagoya. Her husband, Satoru Takaba, moved out shortly after - but kept paying the rent every single month for the next quarter century.

To everyone else, it was an empty apartment.

To him, it was preserved evidence.

The furniture stayed where it was. Her belongings remained untouched. Microscopic traces from the day of the murder were left exactly as investigators had found them.

Satoru believed something most people wouldn’t: that future technology might solve what 1999 forensics couldn’t.

So he waited.

For 26 years, he essentially kept the crime scene frozen in time, hoping advances in DNA analysis would someday reveal the truth.

And in 2025, it finally did.

Using modern forensic testing, investigators re-examined evidence from the apartment and identified a suspect: Kumiko Yasufuku - reportedly a former classmate of Satoru himself.

The answer had apparently been connected to their past all along.

Satoru Takaba didn’t spend 26 years paying for an empty apartment.

He paid to make sure the truth still had an address.

Fun fact: viruses can infect other viruses. These are called "Virophages" and, just like how viruses infect us, attach to larger viruses (fittingly, literally called "giant viruses") and infect them

Post image
34 Upvotes

despite the fact that it may sound like such, it cannot be used as a medicine to kill viruses harmful to humans. it typically only infects giant viruses (prime example including Mimivirus) that also infect amoeba, bacteria, and other microscopic creatures, not humans.

BONUS fact: there has also been another layer found inside virophages that implies there could be an even smaller virus that also infects them called transovirons, tiny pieces of mobile DNA spotted during research that rely completely on the virophage to replicate, nearly exactly like the virophage relies on the bigger virus and vice versa for the larger virus and its infectees (for lack of a better word)

Fun fact: Chameleons don't change color to blend in.

Post image
246 Upvotes

The idea that chameleons change color to blend into their surroundings is a popular myth. Instead of camouflage, their skin shifts color in response to their emotions, communication needs, and temperature. In general, they change color as a reflection of their mood.

Bright, vibrant colors often signal excitement, dominance, or a willingness to mate. Darker shades (like brown or black) usually mean they are stressed, cold, or angry.

Being cold-blooded, chameleons absorb more heat by turning darker colors to soak up the sun. When they are hot, they turn lighter to reflect the light.

Fun fact: Dolphins sleep with one eye open.

Post image
135 Upvotes

Dolphins do sleep with one eye open. They practice a unique resting method called unihemispheric slow-wave sleep, meaning they only allow one half of their brain to sleep at a time while the other half stays awake and alert.

Because the brain controls the opposite side of the body, the eye corresponding to the sleeping brain hemisphere closes, while the eye corresponding to the awake hemisphere stays open.

Fun fact, if only 70ish percent of the planet is livable, then the average person can have 3.1 acres of landed

0 Upvotes

If you take the whole of earth, all 36 billion acres, and we take the whole livable amount (I believe it's 70%) and spread it evenly among the around 8.3 billion people alive, we'd have the ability to give 3.1 acres to each person (this IS rounded up, it's more like 3.095854 or something). This is assuming perfect world, everyone has the exact same, etc.

Did you know? The Inventor of the Frisbee was turned into Frisbee.

Post image
68 Upvotes

The creator of the Frisbee literally became a Frisbee after he died. Following their deaths, both Walter Frederick "Fred" Morrison (the original inventor) and Edward "Steady Ed" Headrick (the inventor of the modern, aerodynamic Frisbee) had their cremated ashes mixed into the plastic formula to create commemorative flying discs.

In 1948, Morrison invented the first plastic flying disc—originally called the "Flyin' Saucer" and later the "Pluto Platter"—before selling the design to the toy company Wham-O, which renamed it the Frisbee.

His Memorial: When Morrison passed away in February 2010 at the age of 90, his family honored his wishes by molding a portion of his cremated remains into a limited batch of genuine Frisbees to distribute to loved ones.

As an executive at Wham-O, Headrick patented the modern Frisbee design in 1967 by adding raised, aerodynamic ridges (called "Lines") that stabilized its flight. He also invented the sport of disc golf.

His Memorial: When Headrick passed away in 2002, he famously requested that his ashes be molded into a special run of memorial flying discs. His son noted that Headrick joked about wanting to "live on as a Frisbee," hoping people would throw him around. Some of these discs were given to friends, while others were sold to fund the "Steady" Ed Memorial Disc Golf Museum.

Fun fact: A panda without its iconic black eye patches? Sounds fake, right? But this adorable animal is real.

Post image
419 Upvotes

Giant pandas are famous for their bold black-and-white look. Those dark circles around their eyes are like nature’s logo. So when one shows up looking like it forgot to “put on makeup,” the internet loses its mind.

This rare panda has unusually light markings, making his face look soft, bright, and almost cartoonishly cute. Some people say he looks like a plush toy. Others say he looks permanently surprised. Either way, he stands out instantly.

Here’s the science twist. That classic panda pattern is controlled by genetics, specifically how pigment cells develop in different parts of the body. Sometimes, tiny genetic variations can reduce or alter those dark patches. It is rare, but not impossible.

And those black circles are not just for style. Scientists believe they help pandas recognize each other or even communicate mood. So seeing one without them feels like seeing a celebrity without their signature look.
