10 Curiosities You Probably Didn’t Learn in Biology Class

The world is a big, wonderful place full of facts we never thought possible. For instance, if a pregnant mouse has a sudden medical issue, the fetus will send stem cells to heal the mother, increasing its chances of survival as well. Fetal stem cells have been found in human mothers as well, dubbed by science as microchimerism.

Bright Side dug up some more marvelous facts about nature and its creations, upholding our yearly resolutions to spread knowledge and joy.

1. The heart slows when your face touches water.

As mammals, we can’t breathe underwater, so as part of the mammalian dive reflex, our heart rate goes down in the water — more so if we go underwater. Even splashing the face with water makes the heart slow down, making it a great way to calm down.

2. Fungus can break down plastic in weeks.

It is said that in the future, there may be more plastic in the ocean than fish. This is why the plastic-eating fungus is great news, and there are around 50 new species of such fungi discovered already. One of the fungi discovered can digest plastic within 2 months, so there’s hope for us yet.

3. Newborn babies can support their own weight.

Newborn babies are strong — strong enough to be able to grasp things in their tiny fists and even support their weight as shown by an experiment done in the nineteenth centuryLouis Robinson witnessed babies able to hang from a walking stick, from 10 seconds to 2 minutes and 35 seconds.

4. Koala fingerprints have been mistaken for human ones.

We’ve been told that our fingerprints are unique, and they are. But the fact remains that even though we share a common ancestor with the koala that was alive 100 million years ago, koala fingerprints look very similar to human fingerprints, as do chimpanzee fingerprints for that matter.

5. Snails can sleep for 3 years.

If you thought bears had it good with hibernation, meet the snail. Snails can sleep rather than hibernate for 3 years at a time without needing food. Of course, this is with some snail species, not all of them. Meanwhile, bears usually hibernate for just 4-8 months.

6. Sloths need 2 weeks to digest food.

Sloths don’t only move in slow motion — even their insides move slowly, ostensibly to preserve energy, which is why a sloth’s digestive system takes 2 weeks to process the food it ate. Plus, most of what it eats is indigestible, giving it very little energy from each slowly chewed mouthful.

On the other end of the spectrum lies the shrew, whose digestion takes mere minutes and is done so fast, not much of it is fully digested. This is the reason why shrews eat their own feces. They can die of starvation in a matter of hours if they don’t eat.

7. Your brain ignores seeing your nose.

We can see our nose all the time, it’s just that the brain tends to ignore it because it’s a constant visual stimulus. It’s the same with people who wear glasses. After a while, they simply stop noticing them.

8. Your forearm is the same length as your foot.

If you don’t have the time to try on a shoe, measure it from your elbow crease to your wrist. If it fits or is just a little smaller, it would fit your foot because the length of your forearm is the same as your foot. And this is just one of many human body ratios that are a marvel in themselves, including the fact that your femur bone is one-quarter your height.

9. You can “see” your white blood cells.

If you look up at a cloudless, bright blue sky and see some wiggly things at the periphery of your vision, you’ve just experienced the blue field entoptic phenomenon. The wiggly things are white blood cells moving in the fine blood vessels moving in front of the retina, at the back of the eye.

10. Human beings have striped skin, but only cats can see it.

Human beings have stripes and patterns on the skin too, and they are called Lines of Blaschko, name eponymously by the scientist who discovered them, Dr. Alfred Blaschko. These are closer to tiger stripes, forming more of a V-pattern fanning out from the center to the extremities. These lines are visible under UV light, a spectrum that cats can see too, which is why cats can see you as a striped being as well.

Which of these facts turned out to be a revelation for you? Share your extreme nature facts with us and blow us away.

Priest Conducting Funeral Service for Wealthy Woman Leaned over Her Coffin – He Was Stunned to the Core by What He Saw

When Father Michael is conducting a funeral service for a woman, he notices an oddly shaped birthmark on her neck, exactly like his own. What comes next is a journey of self-discovery through the grieving process. Will Father Michael get the answers he so desperately wants to find?

The cathedral was silent, veiled in the heavy air of loss. Shadows from towering candles flickered along the marble floor as mourners dressed in black filled the pews, their heads bowed in reverence.

Eleanor, known throughout the community as a generous but reserved woman, had left behind both a sizable fortune and an enduring mystery.

Father Michael took a deep breath, the weight of yet another funeral pressing on him as he approached her casket. He’d never met Eleanor in person, yet something about her presence had always seemed familiar, almost hauntingly so.

As he moved closer, a strange compulsion stopped him. It was something that he couldn’t explain.

He paused, then leaned in, bowing his head to begin the prayer. But as he did, his gaze drifted to her neck, and he froze.

Just behind her ear, a small, purplish birthmark stood out against her pale skin. It was almost shaped like a plum, the same shape and color as the one he had carried his whole life.

“How?” he muttered. “What does this mean?”

A chill shot through him, his hand reaching up to press against his neck. He was well aware that everyone was looking at him, but still, he couldn’t help himself.

This is impossible, he thought.

His heart hammered as memories flooded him, half-forgotten sounds and incidents from his years in the orphanage, from the searches for any record of his parents. The longing he’d held onto for so long stirred within him, demanding answers.

Is there a connection between Eleanor and me? he wondered.

After the service, as the organ played its final verse, the mourners began to disperse, and Father Michael approached Eleanor’s children. They were all clustered near the altar, as her daughters decided who was taking home the floral bouquets.

His request hung on his lips like a prayer he wasn’t sure he was ready to speak.

“I’m sorry for interrupting,” he said. “But I… I need to know something.”

“Of course, Father,” Jason, the youngest son, said. “Whatever you need.”

“I just wanted to know if there’s any chance that Eleanor… if she might have had a child. Another child, I mean. Years ago. Many years ago?”

Eleanor’s eldest son, Mark, frowned deeply, exchanging a wary glance with his siblings.

“I’m sorry, Father, but what are you saying?” he asked. “Do you know something we don’t?”

“Did our mother come to you in confidence? Was there a confessional?” one of the daughters asked.

Father Michael took a deep breath and swallowed his nerves.

“I don’t know,” he said, looking at Mark. “And no, your mother didn’t come to confessional. But I have reason to believe that it is true… If… if I could request a DNA test, just to put this to rest, I would be grateful.”

A wave of discomfort swept over the group, some of them shifting uncomfortably. Mark’s face hardened, skepticism clearly written all over.

“With all due respect, Father, this sounds preposterous. Trust me, our mother was an upstanding woman. She would have told us if something like this were true.”

Father Michael shifted on his feet.

“I understand that,” he said. “It’s just that Eleanor could have had her child very young, and while she wouldn’t have done anything wrong by allowing that child to be adopted, the child still exists.”

Father Michael knew he was speaking as a priest, but he couldn’t turn it off. He had been trained to speak softly and objectively. And even now, he didn’t know how to fight for this DNA test.

Instead, he nodded and began to back away before anything else happened.

“Wait,” Anna, Eleanor’s youngest daughter, said. She stepped forward, her gaze soft as she studied him.

“If you believe that it could be true, then I’ll do the test. I’d want answers, too. Are you the child?”

“I could be,” Father Michael said. “It’s that birthmark on her neck. I have it, too. And when I was at the orphanage, the old woman who was in charge of the kitchen said that all she could remember of my mother was the birthmark on her neck.”

A week crawled by, and each day, Father Michael found himself tossing in his bed as he imagined what it would mean if it were true. Then, one morning, an envelope arrived at the rectory. He tore it open, barely able to see through his shaking hands as he read the results.

It was a match.

Days later, Father Michael sat alone in the rectory. Since the results had come out, he had visited Eleanor’s family, hoping they would be willing to listen now the results were concrete information.

Eleanor’s daughters, his half-sisters, were ready to welcome him into the family, but the brothers didn’t want anything to do with him. It was as though having a new “big brother” was too threatening for them.

He didn’t know what else to do. He wasn’t going to fight for a way into their lives and their family. He wasn’t going to push himself in. But it did help that he knew where he belonged now.

Except… the one person with all the answers wasn’t around anymore.

“Father Michael?” an elderly woman’s soft voice brought him back to the present. “I’m Margaret, a friend of your mother. I was Eleanor’s best friend. Her daughter, Anna, told me everything when I went to have tea with them.”

“How can I help you?” he asked.

Her words struck him like a blow. Your mother. He motioned for her to come in, barely able to speak as they settled into chairs across from each other.

Margaret took a deep breath, her eyes misting over.

“Father,” she said. “Eleanor and I were close, closer than sisters, even. She told me things that no one else knew.”

He leaned forward, his heart pounding.

“Please, I need to know everything. I spent my entire life wondering where I came from.”

Margaret gave a sad smile.

“She was always so careful, our Eleanor. Always afraid of what people would think. But one summer, she met a man, a traveler, a free spirit. He was very different from who we were back then. And she said that he was like no one she’d ever met.”

Father Michael closed his eyes, imagining his mother as a young woman, full of life, swept away by the prospect of love. He didn’t speak; he was afraid that if he interrupted, the truth would slip through his fingers.

“She didn’t even tell me at first,” Margaret continued. “When she found out she was pregnant, she was terrified. Her family had expectations. A child born out of wedlock would have ruined her. So, she concocted this story, and she told everyone that she was leaving for the North Pole, studying penguins of all things.”

The old woman chuckled and sighed.

“I thought it was absurd, but she left. She had you in secret and arranged for you to be taken to the orphanage.”

Father Michael’s throat tightened, emotions too tangled up to unravel.

“She gave me away to protect her reputation?” he asked.

“Oh no, Father,” she said. “It wasn’t about reputation, it was about survival. Eleanor loved you. I knew that. She would check in at the orphanage from time to time.”

“She asked about me?” he asked.

“Oh, yes,” Margaret said, smiling. “She kept track, as best she could. She couldn’t be in your life, but she made sure you were safe.”

Father Michael’s heart ached.

“I spent my life thinking that she’d abandoned me. And all this time, she… she was watching from a distance?”

“She didn’t forget you. It broke her heart, Father. She loved you in her own, quiet way. She just had to do this because it was either this or… who knows what your grandfather would have done.”

She’d loved him, even if he’d never felt it, even if she’d never told him herself.

In the weeks that followed, Eleanor’s family decided to embrace Father Michael with cautious but open arms. Anna became a steady presence at the rectory, often stopping by with scones or muffins and ever-ready to fill him in on family stories, recounting memories of Eleanor.

One afternoon, as Father Michael sat in his office, Anna came by with a small, worn photo album.

“I thought you might want this,” she said, placing it in his hands. “It’s… all the photos we have of Mom. Maybe they’ll help you piece her together.”

The next day, Father Michael found himself at Eleanor’s grave.

“I forgive you,” he said. “And I thank you for watching over me.”

A Homeless Man Approached Me and Showed Me a Birthmark on His Neck Identical to Mine

I never imagined a quick lunch break would lead me to the man who might be my father — a homeless stranger with the same birthmark as mine. As we wait for the DNA test result that could change everything, I can’t shake the feeling that my life is about to take a turn I never saw coming.

I stepped out of the office, loosening my tie as I hit the street. The sun was glaring, and the city buzzed around me, but all I could think about was grabbing a quick bite before my afternoon meetings. Work was nonstop these days, but that’s what comes with the territory. I’ve worked too hard to get here to complain now.

Growing up in that old trailer with Mom, life wasn’t easy. We didn’t have much, but she made sure we had enough. Mom, Stacey, was a force of nature.
