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.

If you see a man with one painted fingernail, here’s what it means

Elliot Costello’s life was drastically altered in a way he never would have imagined in 2013 after traveling to an orphanage in Cambodia.

He was unaware, though, that a meeting would occur that would alter thousands of other people’s lives as well.

It all began in 2013 when Australian social entrepreneur Elliot Costello got to know a young child named Thea.

The 10-year-old girl, Thea, had been saved from a horrible situation, but regrettably, she had wound up in an orphanage. She had been sexually and physically abused for two years, and the torture had a lasting effect. Regretfully, if Elliot hadn’t existed, we might never have learned about this courageous young girl.

However, let’s start at the beginning.

Thea’s life was happy once she was born. The Cambodian girl was loved and cared for by her mother, father, and other family members just like any other child. Unfortunately, fate had other ideas for her. Her father unexpectedly passed away one day, and his loss was tragic in many ways. Not only had it been a painful and emotional experience, but Thea’s father had been the only provider for the family. The family was left in dire straits after his death.

When things became so awful for Thea, her mother had to make the painful choice to place her daughter in an orphanage since she was no longer able to care for her. Sadly, the little girl would end up spending a miserable life there.

The director of the orphanage allegedly sexually and physically abused Thea every day for two years, according to Polished Man.

Thea was eventually moved to another Hagar International-run orphanage in Phnom Penh. Australian social entrepreneur Elliot Costello became close to the boy during a visit there by playing games of naughts and crosses. The 10-year-old child, in spite of everything she had experienced, exuded happiness and optimism.

Thea used to constantly have nail polish on her tiny nails, so one day she wanted to paint Elliot’s. They had a great time together as they sat and chatted.

“I promised her that I would always remember her and her suffering,” Elliot remarked as she painted one of his nails

Elliot was inspired to try and modify men’s behavior after meeting with Thea in order to reduce the number of children who experience sexual abuse. In order to demonstrate support, he also came up with the idea to launch a trend where males paint their nails.

Another symbolic interpretation of painting one nail is that it stands for the one in five children who may experience sexual abuse. It is immediately clear from looking at the numbers that we must put in a lot of effort to solve this problem.

Nearly 70% of all reported sexual assaults involve minors who are 17 years of age or younger, according to the YMCA. Unbelievably, one in six boys and one in four girls will experience sexual abuse before they become 18 years old.

Elliot believes that since men account for over 90% of this kind of abuse against children, they should be the ones to drive change. In light of this, a large number of international superstars have joined the nail painting craze.

Polished Man is still working to provide a better, safer environment for children today. Their principal goal is to stop child sexual abuse. “Being a Polished Man means challenging violent behavior and language, both locally and globally,” the organization states.

Chris Hemsworth is one well-known person who has taken a strong stance; he posed for the organization with a painted nail.

It takes more than just remembering to purchase flowers, shouting rounds, or lifting a lot to be a @PolishedMan. Saying no to violence against children is the main goal, according to Hemsworth.

Famous surfers Kelly Slater and Zac Efron also participated in the social media challenge, and maybe more people will openly speak out against child abuse.

Although the campaign began quietly a few years prior, by 2014 it had drawn the interest of numerous prominent media outlets.

The organization has persevered in its hard work and has now existed for a decade. Polished Man claims that $8.7 million has been raised to fund trauma prevention and recovery initiatives for women and children who have experienced or are at danger of experiencing violence in Australia and other
