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.

During an Argument on the Road, My Husband Threw Me Out of the Car 30 Miles from Home

Scarlett’s weekend escape turned into a nightmare when her husband’s jealously got out of hand and she ended up stranded thirty miles from home. She had no idea that karma would provide an unexpected turn of events that would reverse the situation and give her a sense of fairness again. I’m Scarlett. Hi. I recently got back from what was meant to be a fantastic weekend getaway with my husband, Sheldon. Our marriage had lasted for a decade. I get along well with you most of the time.

But tensions do arise occasionally. Things took a bad turn this past weekend. After spending two days in a quaint little town, we were on our way back. The sun was bright and we had been to several beautiful locations. We had pleasure in boat rides, lovely parks, and cozy cafés. It seemed like the ideal diversion from our hectic life. Sheldon was content, and I was relieved to see him unwind once. Everything was great till the very last day. We went to a little eatery for lunch. Sheldon thought our waiter was a little too chatty. He was certainly pleasant enough. He began teasing the waiter about how attentive he was. I dismissed it with a laugh, but Sheldon became upset. What piqued his interest in you so much? We walked to the car and Sheldon inquired. Trying to keep the conversation light, I answered, “I think he was just doing his job.” Sheldon remained silent as we climbed into the vehicle. At first, the drive home was calm. I tried to savor the remaining moments of our journey as I gazed out the window. However, I could sense Sheldon’s resentment building up next to me. They were on the road for almost an hour when Sheldon finally spoke. He spoke in a frigid tone. “I observed your gaze on him.” With a sigh, I had a knot in my gut. “Sheldon, I wasn’t giving him any particular attention.” He tightened his hold on the steering wheel. “If I hadn’t been here, I doubt you would have refrained from flirting!” That remark hurt. I looked up at him. “You can’t really say that? I’d never be unfaithful to you! He snapped back, “Well, you sure had a funny way of showing it.” My heart was racing. “You’re acting absurdly.

He was just going about his work as a waiter. The dispute swiftly became more heated. In minutes, we went from a tight stillness to yelling. Sheldon’s words wounded more than they had before. Even though his envy was unjustified, he wouldn’t let it go.”You have no idea how it feels,” Sheldon said, raising his voice. “Observing you grin at a different man.” “This is unbelievable,” I murmured while shaking my head. Sheldon, you have my affection. You can’t trust me, why? My heart leaped as he abruptly stopped the automobile. “Leave,” he uttered with clenched teeth. Startled, I questioned, “What?” “Go outside and stroll back home!” he said again, his eyes flaming.

His serious expression conveyed that he wasn’t kidding, even though I couldn’t believe he was serious. With tears hurting my eyes, I opened the door. I slammed the door behind me and muttered, “Fine.” I watched from the side of the road as Sheldon drove off, leaving me by myself. I started to move, a mixture of anguish and rage in me. I was baffled as to how our idyllic weekend had devolved into this nightmare. I had problems with Sheldon, but nothing like this I had ever anticipated.I took to the roadside and began to stroll. The air was growing chilly as the sun descended. Not only was I cold, but I was also shocked by what had transpired. I held out my thumb in the hopes that someone would see me and offer to help. Vehicles zoomed by, their drivers giving me curious or disinterested looks. My thoughts raced, repeatedly playing out the disagreement that I had with Sheldon. He had no idea that I would ever be unfaithful to him. Although his jealousy had never been good, this instance it had taken a toll. After what seemed like an endless amount of time, a car eventually slowed down and stopped over. The man behind the wheel, a kindly-looking middle-aged man, rolled down the window. Need a lift, he enquired. With a wave of relief, I said, “Yes, please.” “Many thanks for that.” Feeling relieved to be off my feet and out of the cold, I got into the car. The chauffeur beamed at me. “My name is Tom,” he introduced himself. “Where are you going?”Home,” I answered. “This is around thirty miles away.” Tom nodded and got behind the wheel. “You know, it was a rough day?” I sighed and added, “You have no idea.” “After a heated argument, my spouse abandoned me by the side of the road.” Tom gave me a pitying glance.

“I regret learning that. Would you like to discuss it? I told Tom about the weekend, the waiter, and the out-of-control dispute as we drove. Speaking with someone and getting everything off my chest felt fantastic. Tom carefully listened, occasionally nodding. When I was done, he responded, “Sounds like your husband has some serious trust issues.” Yes, I replied. “I just don’t get why he doesn’t think I’m trustworthy.” For a while, we drove in quiet as I glanced out the window, thinking back on all that had transpired.

Sheldon was the love of my life, but his jealousy was breaking us. If he didn’t think I was trustworthy, how could we go forward? Abruptly, I noticed a recognizable vehicle off to the side of the road. A beat skipped in my heart. Behind the car, which belonged to Sheldon, were flashing police lights. “Tom, that’s my husband’s car,” I said. Could you please stop? Tom gave a nod, reduced his speed, and parked behind the squad car. Stepping out, I made my way over to Sheldon, who was chatting with a policeman. When he saw me, he appeared taken aback and slightly ashamed. “What’s happening?” I walked up and asked. The policeman turned to face me. “Ma’am, is this your husband?” Yes, I answered. “What took place?” The officer said, “He was pulled over for speeding and reckless driving.” “We may have to suspend his license and tow his car because this is his third offense.” Sheldon turned to face me, a mixture of desperation and rage. “Please, Scarlett, could you assist me?” I inhaled deeply, attempting to control my feelings. “Officer, may I take the car home?” I asked. My license is still in effect. The officer gave me a long look before nodding. “All right. We won’t need to tow it if you drive. He is still receiving a ticket, though. Taking the keys from Sheldon, I felt vindicated and empowered.

I was the one saving him now that this was his disaster. Upon taking the wheel, I couldn’t help but experience a wave of fulfillment. Sheldon sat dejectedly on the side of the road. He murmured, “Thank you,” as I turned on the ignition. I remained silent. Rather, I concentrated on the path ahead, experiencing a sense of both relief and accomplishment. Now I was in charge. Sheldon had to realize there were repercussions for what he did. I had a strange sense of finality as I drove away, leaving Sheldon to deal with the police. While it wasn’t the solution to our issues, this was a start in the right direction for me to regain my power and independence. I would be there for Sheldon as he faced his own problems, but only if he could learn to trust me. I was happy to drive home for the time being, knowing that karma had truly had the last laugh.
