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.

Her photo wearing a bikini on the beach is being shared but thousands and when the camera zooms out we understand why

What was supposed to be a day filled with fun and joy turned into a tragic incident for the grad-student at The University of Georgia, Aimee Copeland.

That day in 2012, she and her friends decided to go on a trip to a small lake, where they could zipline over the water. This sounded like a great idea which they all loved the moment they heard it.

Unfortunately, when it was Aimee’s turn to have some fun, the the cable snapped and she fell down a cliff. Sadly, she lost her leg that day.

Aimee was rushed to the hospital, and once there doctors had more horrific news. Aimme contracted a very serious flesh-eating bacteria which infected her wound. It was a matter of hours if she would survive or live.

The bacteria she had is known as Aeromonas hydrophila. This bacteria easily leads to a life-threatening condition known as necrotizing fasciitis, commonly referred to as a flesh-eating disease.

It required 11 surgeries for her life to be saved, but she lost both her hands and legs which needed to be amputated.

However, as brave as she has been, this young woman didn’t let the tragedy stay on her way of living her life to the best of her abilities.

Four years after the incident, Aimee shared a photo of herself at the beach, wearing a bikini and putting a huge smile on her face.

Many found inspiration in the photo and it was soon shared on the social media thousands of times with many saying that Aimee is a true inspiration.

She’s proud of herself and of everything she managed to overcome, and what’s most, she’s proud of her body and the way she looks after the ordeal she had gone through.

“It has taken me a long time to become comfortable with and accept my new body. We are ALL made with imperfections and there is so much beauty in our flaws. The scars and skin grafting build character! It’s not about what you have — what you do with what you have is what really counts,” she wrote in the caption.

Today, Aimee is an advocate for amputee and disability rights, and she continues to inspire others through her public speaking engagements and social media posts. What’s most, she’s pursuing a PhD in psychology at the University of West Georgia.

She is the perfect example that nothing can take our dreams away, not even a tragedy like the one she suffered.
