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.

Mom was deeply emotional after her 3-year-old son lost his foot in a lawn mower accident, but he reassured her that everything would be okay.

After a lawnmower accident resulted in the amputation of his left foot, Keirsten Marsico’s little son Joey consoled her by telling her that everything will be alright.

“I was crying naturally when he came out of surgery that night, and he just held my head and said, ‘Mommy, what’s wrong?’” Marsico told PEOPLE his story. “I told him, buddy, I’m really sad.”

Joey Marsico

Joey, who was only a few weeks away from turning four, was watching his grandfather Mark DeLuca mow the lawn outside their Whitehall, New York, home on Thursday, May 9, when he made a snap decision that put him in danger.

Keirsten talked about her “active little boy,” the youngest of her two children, saying that “he really loves tractors and enjoys helping with the lawn.” “He approached my dad, who was riding the lawnmower, from behind. My dad threw the mower in reverse before my mom could get to him, and everything happened all at once,” she remembered. “The events that led to what happened were a series of events.”

“It’s been tough on all of us, especially my parents who feel absolutely awful,” Keirsten continues. Specifically, my dad is distraught.

The family believes that Mark DeLuca’s quick use of a tourniquet probably saved Joey’s life. After being transported to Boston Children’s Hospital, Joey had many foot procedures before it was decided to amputate.

Despite the difficulties in his recuperation, Joey’s maturity and upbeat attitude have astounded his family and friends, as well as his caregivers and physicians.

Joey Marsico

“What a strong little guy,” Keirsten says. At times, conversing with him is like to conversing with a teenager. He has excellent adjustment.

Joey’s father, Joseph, remarks, “He’s always been that way—very understanding, perceptive of people’s emotions, and adept at coping with situations.” Joseph is reflecting on his son’s exceptional maturity. In addition, he speaks a lot and has a vocabulary that is above average for his age.

The Marsicos, along with their autistic 6-year-old daughter Gianna, settled into a new routine during Joey’s almost month-long hospital stay.

“We tried to maintain a sense of normalcy for my daughter because she attends school,” Keirsten says. “My spouse and I decided that one of us should stay at home with her because she needs routine.”

Joseph stayed stubbornly by Joey’s side, while Keirsten stayed at home. “He’s still by Joey’s side,” Keirsten underlines.

Keirsten reflects on a touching incident by saying, “The other day, as I was leaving Joey, I was crying, and he consoled me again.” I told him it was okay and that I didn’t have to be sad as he wiped away my tears. “I know, but I don’t like leaving you,” I said to him.

The Marsicos take comfort in the knowledge that Joey’s accident was a terrible exception and in their Catholic faith.

“My worst fear is that people will hear this story and think, ‘Why weren’t they watching him?’ or ‘How could they let this happen?’” admits Keirsten, expressing her deepest concern. As his mother, I’ve struggled with it.

She does, however, take solace in her faith, thinking that Joey’s experiences have a greater meaning. “I have to constantly tell myself that everything is happening for a reason. Even if we can’t see it now, God has a plan for him, Keirsten says.

She says, “I would tell someone else it’s an accident if they were in our shoes.” “Accidents happen, and focusing on ‘why’ won’t help—it will only make you feel bad about yourself.”

Keirsten highlights how resilient their family has been in the face of hardship. “We must change and get over what is going on. Our priorities are helping Joey and continuing to be a solid family unit.

After being away from home for almost a month following the accident, Joey was released from the hospital on June 5. Earlier last week, he had his fourth birthday celebration.

His parents are hopeful that he will heal and that he will soon get a prosthetic fitted. They are in awe of Joey’s capacity to communicate his emotions and offer consolation to others during this trying time.

Warmly, Joseph says, “He’s always been such a special little boy.”
