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.

Stockard Channing: The star from ‘Grease’ is 80 & looks unrecognizable now

After all these years, I don’t think there’s ever been a more charismatic or relatable Rizzo than Stockard Channing.

Channing was a great artist and her singing was just fantastic in Grease – but nowadays, the 80-year-old looks almost unrecognizable.

The first movie I ever saw Stockard Channing in was called The Big Bus and I thought it was hilarious. But back then, I could never imagine that she would go on and have such a remarkable career.

Today, Stockard Channing is best known for her iconic portrayal of Betty Rizzo in Grease, the 1978 American musical romantic comedy film based on the 1971 musical of the same name. Like many before me have pointed out, Channing was by far the best Rizzo out of all that have played the part.

Many probably also recognize Channing from the series The West Wing, where she starred as First Lady Abbey Bartlet. The experienced actress was praised for her instant chemistry with Martin Sheen, who played President Josiah Barlet.

“It just worked,” she told Entertainment Weekly in 2020.

“We had this chemistry from the beginning. I don’t know what it was, but we had it and it didn’t go away. It was a happy accident.”

Starring as Beth Rizzo

But let’s take a deeper look at the highlight of Channing’s career. Because in the name of honesty, she hasn’t appeared in any major motion picture since Grease, even though she has continued to act in films and on Broadway.

The 13-time Emmy Award nominee and seven-time Tony Award nominee appears to be totally fine with being most remembered for her portrayal of bad girl Beth Rizzo, one of the Pink Ladies in Grease.

But is that really the whole truth?

Back in 1973, Channing had little breakthrough starring in the TV-movie The Girl Most Likely to…, a black comedy about revenge.

“A lot of people talk about the G-word [Grease] and all of that, but back in the day, I had as many people stop me in the street about that one movie. Because it’s about revenge, and people would sit in their living rooms and go, ‘Oh, I’m the only person watching this’ or ‘this person understands me.’ I’m not kidding. It was a million years ago, and then it was the highest-rated movie of the week. Revenge always works,” she says.

According to Channing, she has only watched Grease only two times.

“I used to be grumpy about Grease because I thought it was a kids’ movie or something. But now it’s sort of amazing. I’m very proud of it,” she told The Times in 2019.

The Manhattan-born actress was 33 years old when she played Rizzo and playing a high school teenager wasn’t so easy for her.

”I was so much older than she was in life, but I could not think about that so I sort of threw myself back to what I felt when I was her age over, even younger. The complexity of adolescents and hormones and sexuality and all of that other stuff. Seeing that I really was older I think that added to the isolation of Rizzo,” Channing told Broadway World.

Channing, who became interested in acting at an early age, was thrilled when she was offered the role of Rizzo, and her performance made her a top-ranking star in the late 1970s. She earned a People’s Choice Award for Favorite Motion Picture Supporting Actress, but the New York native had difficulty achieving similar success after Grease.

The beloved actress was handed two sitcoms of her own, Stockard Channing in Just Friends (1979) and The Stockard Channing Show (1980), but neither was successful and her career halted.

But with her look of Elizabeth Taylor and air of calm confidence, Channing didn’t give up and she continued to work as an actress, appearing in many highly-praised movies and stage plays. Her latest appearance on the big screen came was in Angry Neighbors, which premiered in 2022.
