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.

A struggling young mother purchases an old washing machine she could hardly afford, only to discover a note inside

Jessica wanted to buy a $250 washing machine, but she couldn’t afford it, so she had to ask the seller for a discount. He consented right away, to her surprise, but when she got home and opened the machine, she discovered something even more surprising inside.

When Jessica and her husband Edward welcomed their first child, Kathy, they quickly understood that parenting would not be easy. The young parents were having financial difficulties then, and there was constantly a lack of funds.

Edward owned a textile business in Texas, but it was struggling. Meanwhile, Jessica worked as a nanny on weekends while Edward looked after Kathy. With a baby at home now, expenses went up, while income stayed the same or even went down some months.

Ahh, it must be challenging for them too. Perhaps more difficult. Jessica reflected as she drove away from work one weekend, glancing at her neighbor Sandra and her children.

Sandra was already raising a third child even though her husband was just a truck driver. Although he got paid on a piecemeal basis, he wasn’t rowing millions of dollars there. Sandra had been working on a farm for several years to help support her husband financially, and it was the only way they could make ends meet.

Jessica and Edward, like their neighbors, were scraping by on whatever they could. Edward had stopped going to bars with friends to conserve money after Kathy’s arrival, and Jessica had given up on the little things she had managed to buy after saving money from the monthly budget.

Luckily, one month, things were going well financially. Edward’s business grew slowly but steadily, and Jessica managed to save some money. But just when it appeared like they would be having a less stressful month, another problem knocked at her door: the washing machine broke down.

After considering her options, Jessica realized that there was no point in getting the machine repaired. The labor and motor replacement cost would be slightly less than the cost of a new machine, and there was no guarantee that the repaired equipment would last as long. After all, this was the fourth time the machine demanded a repair in the same year.

Knowing there was no other option but to look for a new machine, Jessica sat down on the computer, looking for an affordable one. An hour of searching led her to one suitable find, but it cost $250, and Jessica could only afford to pay $150.

In the end, she decided to see the merchant in person and request a discount right then and there. James Carter, 1216 East Madison Street, Brownsville, TX, said the advertisement. Jessica made a note of the owner’s address.

Upon arrival, a man about Jessica’s age opened the door. There was a calmness in his eyes, but the dark circles beneath them revealed inner stress and exhaustion. “How may I assist you?” he asked, his voice deep but mournful.

“Hi, are you James Carter? I’m Jessica Turner. I messaged you regarding the washing machine. Can I have a look at it?”

“Oh, Jessica. Yes, sure. Come in,” James said, and Jessica followed him in.

The entire house was in shambles, and Jessica deduced from the disorganized layout that the man was planning to relocate, which was why he’d put the machine up for sale. As she entered the room next to the hall, she saw the white washing machine. It appeared to look brand new, precisely as she’d seen it online.

“Well, I hope you remember I said I wanted to talk about the price,” Jessica said, having viewed the machine from the exterior. “I can’t afford to pay $250! I agree the machine still looks brand new and everything, but I can’t extend my budget beyond $150. We just had a baby, and you know things are not so well financially, so I was wondering if you could please give me a discount?”

James stood there silent for a while, pondering, and then nodded his head in agreement. “Sure. I don’t mind. $150 sounds like a good deal to me,” he said absentmindedly and then turned around to lift the machine.

Jessica’s eyes widened in surprise. “Really? Thank you! Thank you so much!”

James gave Jessica a slight smile and the woman could sense that his thoughts had wandered beyond the room in that short while, but she didn’t bother much about it as she was rejoicing in luck.

After 5 minutes, the two of them carried the huge machine to Jessica’s car without gloves, belts, or loading belts, huffing and sweating. She’d already paid James and was looking forward to getting the machine home.

As she prepared to leave, she gave her hand to say goodbye and asked him to meet her somewhere in the future, but James’ answer was a flat no. “I’m leaving this place for good, and I won’t be returning, so I don’t think we’ll be meeting again. Anyway, I hope the machine is useful to you,” he said with a quick but honest smile. Jessica simply smiled at the odd response and thanked him once more before leaving.

When she got home, the first thing she did was double-check the equipment’s functionality. However, as she opened the dryer to check the lint filter, she was shocked to find $150 in there.

It also contained a folded piece of paper in one corner with a message. “It’s a gift for your newborn baby,” it read. “I didn’t think it was fair to ask for money from someone who was already struggling financially.

“As a result, I chose to return it. Someone very close to my heart once told me that if I have the resources, I should help those who are less fortunate.” Jessica was shocked. When did he place this inside the machine?

Suddenly, it hit her. She’d asked him to help her move the machine to the yard while she fetched ropes from the car trunk to pack the machine properly, and it’s possible that’s when he put it there.

Jessica wanted to express her gratitude to him for his assistance. However, because he didn’t provide a phone number on the website and returning to the house would be a two-hour journey from her home, she decided to see him the next day.

Unfortunately, it was too late by then, as the man had already left the house, and a for sale sign was posted in the yard. Jessica left the house dejected, thanking him once more in her heart.

One year later…

Jessica and Edward were finally moving into a larger home. Kathy had been accepted to a good school, and Edward’s business was doing well.

Jessica was standing on the balcony of her former house, surveying the area where she’d spent most of her days. The place held a lot of memories for her. She switched her sights to Sandra’s residence and overheard Sandra and her husband bickering over purchasing a new washing machine.

Jessica took a look at the wet linen-laden rope on Sandra’s terrace. Oh, that poor woman must have done all the laundry herself. I should do something to help her.

So before leaving, she rang the doorbell at Sandra’s and left the washing machine on her doorstep with a note that read, “With love from your neighbor, Jessica.”

Jessica saw how happy Sandra was when she opened the door and spotted the machine on her porch.

So this was how James felt when he helped me. Ahh, honestly, it does feel amazing. However, I’m still curious about who encouraged him and asked him to assist people in need. Jessica pondered as their car sped away to their new destination.

What can we learn from this story?

Never hesitate to assist someone in need if you have the means to do so. The way Jessica helped Sandra and James helped Jessica are beautiful examples of this.
Learn to emulate the goodness of your surroundings. Jessica was inspired by James’ example and stepped in to assist Sandra.
