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.

“Stop Equating Thinness With Health and Happiness,” How Lena Dunham Inspires People to Fall in Love With Their Curves and Scars

There are so many things in the world that we may admire or even get inspired by, but there’s one main thing we may want to fall in love with before we start noticing the beauty of other things. It’s our own reflection in the mirror. Among all the numerous recipes for conjuring up self-love within ourselves, psychologists advise us to never compare ourselves to others and stop caring about other people’s opinions. Actress and producer Lena Dunham knows a lot about cultivating love for her own body despite all the criticism she faced, and she happily shares her journey with us all.

Lena Dunham doesn’t accept the term “body positivity,” and here’s why.

Actress and writer Lena Dunham has recently added another string to her bow and collaborated with the brand 11 Honoré to create a plus-size clothing collection. But the very term “plus size” frustrates Lena, and so is the term “body positivity.” In one of her Instagram posts, she explains that she feels more “body tolerant” than “body positive.”

In her interview, Dunham said, “The thing that’s complicated about the body-positive movement is it can be for the privileged few who have a body that looks the way people want to feel positive. We want curvy bodies that look like Kim Kardashian has been up-sized slightly. We want big beautiful butts and big beautiful breasts and no cellulite and faces that look like you could smack them onto thin women.”

Dunham has a very special relationship with her own body.

Dunhams path to self-love started with a decade-long journey with endometriosis. Since she started her own fight against it, she has been candidly sharing how it influenced both her emotional health and her relationship with her own body image. In her Instagram post, she emotionally described how she fluctuated between loving her body and the opposite.

She wrote, “Ya know when you’re home alone, and you realize you’d be happier in a hot lil’ onesie than your ketchup and cat food stained pajamas? And it’s not about a boy or a photo shoot or a weight loss before-and-after, it’s just for the feeling of glee you get from dressing your one and only corporeal form in pleasing fabrics, the unique pleasure of admiring the twists and turns of the body that loves the heck out of you even when you don’t love it.

Dunham is powerfully addressing all people who come to her page with criticism.

In 2021, Dunham tied the knot with musician Luis Felber. It was such a darling event for her that she wore 3 wedding dresses to marry her love and shared the photos on her Instagram. However, she started getting some “gnarly” comments in her feed from people who commented on her body and appearance. The actress didn’t hesitate for a minute to address them with a powerful message.

She wrote, “One narrative I take issue with, largely because it’s a story I don’t want other women, other people, to get lodged in their heads, is that I should somehow be criticized because my body has changed since I was last on television. […] But lastly, when will we learn to stop equating thinness with health/happiness?

Dunham’s powerful message can be echoed in the hearts of many.

For all people who have ever hesitated about embracing their body image, Dunham has some simple yet wise advice. She says, “Of course weight loss can be the result of positive change in habits, but guess what? So can weight gain. The pics I’m being compared to are from when I was with an undiagnosed illness. In the last 4 years, I’ve begun my life as someone who aspires toward health and not just achievement.

These changes have allowed me to be the kind of sister/friend/daughter that I want to be and yes — meet my husband (who, by the way, doesn’t recognize me in those old photos because he sees how dimmed my light was). I say this for any other person whose appearance has been changed with time, illness, or circumstance — it’s okay to live in your present body without treating it as transitional. I am, and I’m really enjoying it. Love you all.”

Do you find Lena Dunham’s example inspiring? What do you love the most about your appearance?
