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.

Man Divorces Wife After the Birth of Their Fifth Daughter, Accidentally Meets Her Years Later – Story of the Day

Matthew filed for divorce from Anne when she couldn’t give him a son, but he still lived in their house. One day, she met Harry, an old friend from school, and eventually realized how much better she was without Matthew. Years later, Anne accidentally ran into her ex-husband and couldn’t recognize him.

“Oh my God! Harry! It’s so nice to see you!” Anne exclaimed when she accidentally stumbled into her old school friend on the street. She had left her five girls with her mother, a rare break for her, and wanted to get a cup of coffee on the streets of Seattle.

“Anne, it’s lovely to see you too! Hey, would you want to get some coffee and catch up?” Harry answered, and she nodded immediately. They went into the café and chit-chatted until Harry asked about her family.

“Oh… that’s actually a difficult subject,” she began.

“Well, raising five children is not easy for anyone,” Harry commented, knowing a bit of her from social media and such.

“Matthew? What are you doing here?” she asked, looking at his uniform and the pretzel tray.

“Yeah, sure. That’s hard. But it’s more than that,” Anne continued. “Matthew changed after the birth of our twins. They’re 9 and they barely speak to their father. I think they’re scared of him.”

“I don’t understand,” Harry said.

“Matthew wanted a boy, and we hoped, but we had two beautiful girls instead. That’s why we got pregnant again and again, but we kept having girls. After our fifth daughter was born, Matthew became another man. He filed for divorce, and I don’t know what I’m going to do,” Anne explained about her husband, her hand wiping the sweat forming on her forehead.

“Wow. That’s rough. But think about this, you’ll be better off without him, right? I mean if he hasn’t been speaking to your eldest girls, then he couldn’t have been the best father to the rest. You already raised them on your own,” Harry encouraged. “And now that I’m in Seattle permanently, I could help. You could move in with me.”

Anne’s jaw dropped. She didn’t expect such an offer from Harry, especially since they had just met again after many years. But she knew back in school that he always had a huge crush on her. Still, that offer was too generous and kind. She couldn’t accept it. She changed the subject, and they talked about his successful life.

Meanwhile, things at her house got even worse over the next few weeks. They were divorcing, but Matthew still lived with her, acting like he was single, partying, making noise at odd hours, waking the girls, and being a menace to them.

Anne would talk to Harry all the time, and his offer still stood. But when Matthew decided to bring a girl over to their marital home, Anne was done. She called Harry, packed, and left the house with all the girls.

Their divorce got more complicated when she took Matthew to court to get their big house back. Despite her living in Harry’s house, her soon-to-be ex-husband didn’t deserve to keep their big home. The judge granted her every request based on Matthew’s horrible lifestyle and gave her full custody without question.

Eventually, she and Harry fell in love, and he bought an even bigger home for their family. When she and the girls moved in with him, she put her house up for rent and stopped thinking about Matthew for many years.

***

A year after marrying Harry, Anne had their son, Alan, who was the most beautiful boy in the world, and he had five big sisters adoring him at every moment. Anne couldn’t have been happier.

More time passed, and one day, she picked Alan up from preschool and decided to drop by the mall to buy him new shoes. The girls were busy with their extracurriculars, so it was only mother and son.

Anne never imagined she would run into Matthew there. He was working at the pretzel shop, in charge of distributing free samples at the mall, and Alan ran up to him asking for some.

“Alan, don’t run away from me like that,” she said to him before catching a glimpse of Matthew’s surprised eyes.

“Anne?”

“Matthew? What are you doing here?” she asked, looking at his uniform and the pretzel tray. It didn’t make sense. Matthew worked in an office as an executive. He earned a decent amount of money. He was required to pay tons in child support, but he never did, and Anne didn’t care. She had more than enough for her girls. But he wouldn’t be able to pay what was required with a minimum wage job at the mall.

“I’m working here,” he said and looked at the boy holding her with one hand and munching on a pretzel with the other. “Is this your son?”

“Yes, this is Alan,” Anne answered, feeling an intense pride that she had a son that wasn’t his. “He’s Harry’s kid.”

“Oh, nice to meet you, Alan,” Matthew said, looking down and giving the kid a weird look. Of course, it was not Anne’s fault that she gave birth to girls. The sperm determines the gender, and everyone knows that. But Matthew had decided to blame her for years and checked out of their marriage because he wanted a boy, as if gender was important at all.

Luckily, the girls now had an actual father figure, thanks to Harry, who loved them dearly from the first moment they met. They didn’t need him, and Anne never had to see him.

“Listen, Anne. I didn’t want to ask this now. I wanted to take you to coffee or something. But I’m desperate. I lost everything due to my lifestyle, and I was wondering if we could sell our old house,” Matthew asked, his head down in shame.

“Oh… well, it’s currently being rented. But I’ll think about it,” Anne said. “We have to go now. I’ll call you about the house.”

She grabbed Alan’s hand tightly and walked away from the man who didn’t know what he had thrown away. But she was going to be the bigger person. She sold the house and gave him half its worth, although legally, she could keep the entire thing. But something in her gut told her to do the right thing.

Eventually, Matthew asked to see the girls, but none of them wanted that. The twins were teenagers who grew to hate him, and the rest followed their big sisters’ footsteps. Matthew stopped asking about them and stopped calling after a while. They never saw him again. He wasn’t family.

What can we learn from this story?

  • Family is more than just DNA. Matthew didn’t want to be a father to his children, and Harry stepped up for the girls.
  • You might regret your actions. Matthew lost everything, including his high-paying job, and it was clear he regretted what he did, but he couldn’t take it back.
