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.

Woman takes sneak photo behind old man: Reveals what waitress is doing with his food

It’s a common belief that today’s kids lack regard for their elders. That is absolutely true in some cases; young people ought to be more appreciative of those who contributed to the creation of our nation as we know it now.

It’s not always the case, though. Young people engage in a variety of daily activities that are deserving of greater attention.

One such tale is this one. My goal is that we can assist in its propagation such that it creates pond ripples that eventually impact a great deal of people.

In 2018, Evoni Williams, who was then eighteen years old, performed her regular shift behind a counter at Waffle House in Houston.

It was there that she saw an old man who needed an oxygen tank to assist him. He was having trouble slicing his food. Evoni tried to assist the elderly man, whose hands were not functioning as effectively as they used to.

A customer named Laura Wolf wrote, “She took his plate and started cutting up his ham without hesitation.”

She posted a photo of the incident to Facebook since it moved her so much.

Wolf went on, “To him, this may seem small, but I’m sure it was huge.”

“As everything in this world looks so terrible, I’m thankful to have observed this gesture of love and caring at the start of my day.”

US news sites report that over 40,000 people have shared this act of kindness on Facebook, about a week after it was done.

Additionally, the Texas Southern University School quickly received the photo and reportedly extended an offer of a $16,000 scholarship to Evoni.

For Williams, who graduated from high school in May and has been working at Waffle House to raise money for college, it was a present that changed his entire life.

The kid claimed she didn’t think her behaviors were unusual, but she was honored to get the compliments and admiration.

Williams admitted to the Houston Chronicle, “I didn’t know the photo was taken until a couple hours later.”

The eighteen-year-old said it was clear she should be assisting the elderly man.

“It’s just something I would do for anybody, when I saw it.”’

Such tales give one a great sense of warmth. Evoni, more exceptional people like you are needed in the world.
It’s fantastic that this kind deed resulted in a scholarship. Kindly post this narrative on Facebook. It will encourage more people to give to charity in their daily lives.
