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.

She Really Needs New Pants’: Users Discuss Jennifer Lopez’s ‘Dirty’ Jeans on an Outing with Daughter Emme

Jennifer Lopez was photographed in jeans covered with dirt while shopping with her daughter Emme in Los Angeles, on October 30, 2024.

The pop star stepped out confidently in a relaxed, casual outfit recently, but fans were quick to express their disapproval of her jeans, questioning their style and age appropriateness.

Lopez popped out with her daughter Emme in Acne Studios’s Super Baggy Fit Jeans, which are mid-waist. The brand’s website describes these super wide-leg pants as having “fading and smudging throughout,” contributing to a trendy construction worker-chic aesthetic that is currently fashionable.

To balance the shabby aesthetic of her wide-leg pants, “The Mother” star paired them with refined pieces, including a ribbed & Other Stories Mock Neck Jumper and a large Bottega Veneta tote bag.

On her feet, she wore Classic Twin Seam New Heights Ugg boots, a modern take on the classic suede style, featuring distinctive seams and a curved sole. Jennifer Lopez and Emme ignored the paparazzi as they stepped into American Rag Cie to shop before Halloween.

Online users had mixed reactions about Lopez’s choice of jeans during this outing. One surprised commenter questioned, “Are her pants … Dirty? Or is that the style these days?” Another seemed puzzled by her choice at her age, remarking, “I really don’t get that st [sic] 55 she dresses like this.”

An online user suggested an upgrade, “She really needs new pants,” while someone humorously urged, “The pants ..please trow [sic] them in the trash please!!!!🤪🤪🤪🤪🤪.” Meanwhile, a disappointed fan asked, “JLO my love what’s with those jeans?😢”

Yet, her look still garnered admiration. Fans wrote simple, approving notes like, “Pretty.” Another admirer gushed, “Beautiful!❤️” An amazed fan also penned, “She doesn’t age 😍.”

Others praised her style overall, “Jlo look [sic] amazing in whatever she wore😍” and another user concurred, “She’s always cute.”

Lopez is often recognized for her timeless elegance in the public eye, some of which stir lively discussions among her fanbase. Her most recent appearance isn’t the first time she has been celebrated by some and critiqued by others for her unconventional denim choice.

In April 2024, she was spotted descending a set of brownstone steps, donning a similar pair of baggy jeans like the one she wore on her outing with Emme. These jeans also appeared distressed and discolored, an unusual departure from her typically polished looks.

She paired the jeans with an elegant, long navy coat, exuding an urban chic vibe, and complemented it with a cashmere turtleneck sweater. Shielding her eyes with large sunglasses, Lopez carried a standout turquoise Chanel bag, adding a splash of opulence to the street-savvy outfit.

Despite her impeccable style history, fans were divided over this latest look. Her enthusiasts lauded her appearance, “That’s how I like her, looking great,” a sentiment seconded by others who felt Lopez could do no wrong, fashion-wise.

A second comment added to the chorus of praise, “Incredibly beautiful and elegant!! Unique Jlo!!!” emphasizing the uniqueness that Lopez brings to her style choices. Another user simply diverged from the matter at hand to declare her love for the star with, “I love Jen.”

Conversely, some fans were less than impressed. A third commenter did not mince words, declaring, “Worst jeans I’ve ever seen on a woman. Another lamented, “The outfit is elegant except for those nasty jeans😒,” while another wrote, “And those jeans look filthy!”

In similar disapproval, another user called the “Love Don’t Cost a Thing” songstress “a mess,” citing the jeans as a significant detractor from the star’s usual elegance. Another blatantly declared, “She has no dress sense!”

Meanwhile, others rallied to Lopez’s defense, clarifying the intention behind the fashion choice. One user provided a counter-narrative, “They are not dirty that is the style of those pants,” suggesting a misinterpretation by the critics.

Criticism aside, Lopez’s hallmark is her adaptable fashion sense—seamlessly shifting from street-chic flair to couture elegance, all while preserving the distinctive personal touches that are unmistakably JLo.

Lopez has long navigated the ever-shifting tides of fashion with grace, as comfortable in the rugged casualness of jeans and Timberlands as she is in the high glamour of Valentino Haute Couture.

“I like baby hairs and big hoops and gold jewelry,” she confessed, revealing the personal flourishes that anchor her diverse fashion choices. These personal touches, regardless of trends, remain steadfastly woven into the fabric of her distinctive look.
