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.

We pulled down a false wall in the cellar of our 1857 house and found this! What is it? Any idea?

May be an image of water heater and hearth

Some of the people comments about this found were:

How come no one talking about the tea kettle that’s just suspended in the air
Weird it was covered
My mother cooked on one of these, she made amazing meals, also bread and cakes, Friday was bake day. We lived on the moors in the borders of England and Scotland. I now live in western Maryland, US.
Excellent find, too bad it was not a treasure chest
That is beautiful. An antique dealer will give you quite a lot of money for that. I wouldn’t move it or touch it until I talk to antique dealers.
What an amazing find. I wonder why the former owners covered that up.
Nice I would start tearing down other walls maybe find something else!
It was probably too heavy to get it out of the cellar so they left it.
Wooooow lucky you I would be over the moon and use it with pride … I remember staying with my nan at weekends she had one and remember her having an iron on there to do her ironing … and doing toast on the fire it was lovely… lucky you ❤️
What a treasure
So the original kitchen may have been in the cellar or it was the kitchen for the servants. Love it
I’d leave it right there. Dust it off. Then design around it. It would be the focal point of your room.
NO!!!is it full size or a child’s size? Whatever! What a FIND!
It appears like they intentionally closed up the fireplace with stove and kettles intact for a future find like this. As a builder/contractor we almost always leave little mementoes or time capsules in the wall or closed off portions of the build. We often include owners information and pictures as well as our information. Coins from the year we did the project. Even bran new tape measures or hammers. Sometimes I’ve included brief essays on current events or political thoughts. It’s fun.
Imagine putting a wall up with the kettles still on the stove!
It looks child Size. That’s truly amazing!
Do you think this was original kitchen?
Wow! They left the tea pots in there!!
I used to black lead one of these for my gran, when I was a child. Of black lead can still be bought ot will come up like new.
That old black grate is in great condition. So what are you going to do with it?
What are your thoughts?
Owning an old house often feels like holding a piece of history in your hands. Each creak and groan of the floorboards, each worn corner, and each weathered brick tells a story. When we bought our 1857 home, we knew it had secrets. Little did we know that one of its most remarkable stories was waiting to be uncovered behind a false wall in the cellar.

The Discovery

Our journey began with a simple home improvement project. The cellar, with its stone walls and cool, damp air, had always intrigued us. One wall, in particular, seemed different. It sounded hollow when tapped and had an odd, almost hidden, seam running down its length. Curiosity got the better of us, and with a few tools and a lot of determination, we decided to investigate.

As we carefully dismantled the wall, brick by brick, our anticipation grew. Finally, the last layer crumbled away to reveal a dusty, forgotten room. What lay within was beyond our wildest dreams.

The Hidden Room

The room was like a time capsule, sealed away and untouched for decades. Dust motes danced in the beams of our flashlights, illuminating a collection of objects that seemed frozen in time. We found old furniture, crates filled with yellowing papers, and a variety of curious artifacts.

Treasures and Traces of the Past

Among the most fascinating finds were:

Antique Furniture: A beautifully crafted wooden rocking chair, a small writing desk, and a trunk filled with linens and clothing from the 19th century.
Historical Documents: Letters, diaries, and legal papers that offered a glimpse into the lives of the home’s previous occupants. One particularly poignant diary detailed the daily life of a woman who lived in the house during the Civil War.
Vintage Tools and Equipment: A collection of old tools, a sewing machine, and even an early model of a phonograph.
Personal Items: Family photographs, a set of silverware, and a few pieces of jewelry that likely held sentimental value.
Piecing Together the Past

As we sifted through the items, we began to piece together the story of the house and its inhabitants. The documents revealed that the house had been a refuge during tumultuous times. The hidden room might have been used to store valuables or even serve as a safe haven during periods of unrest.

One particularly fascinating letter was from a former owner to a relative, describing how the false wall was constructed to protect the family’s most prized possessions from potential looters during the Civil War. This discovery added a layer of historical significance to our home, connecting us to the broader tapestry of American history.

Preserving Our Find

Realizing the importance of our discovery, we decided to preserve and document everything we found. We contacted local historians and museums, who were thrilled at the prospect of examining the artifacts and documents. We even received guidance on how to properly preserve the items to ensure they remained in good condition.

A New Chapter for Our Home

Uncovering the hidden room has deepened our appreciation for our historic home. It’s more than just a place to live; it’s a repository of memories and stories that have transcended generations. We plan to incorporate some of the artifacts into our home decor, creating a small museum-like display to share the history with visitors and future generations.

Conclusion

Our discovery behind the false wall in the cellar of our 1857 house has been nothing short of extraordinary. It serves as a reminder that the past is always with us, waiting to be uncovered and appreciated. As we continue to explore and restore our home, we look forward to uncovering more secrets and preserving the rich history that lies within its walls.
