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.

Shоuld Yоu Rinsе Grоund Вееf?

When it comes to cooking up a storm in the kitchen, ground beef is a culinary superhero. From tacos to spaghetti, this versatile ingredient has the power to turn a simple meal into a flavor-packed feast. But there’s a lingering question that divides kitchen warriors: Should you rinse your ground beef before cooking (or after)?

Some kitchen enthusiasts swear by rinsing their ground beef before (and after) cooking, and they have a few compelling reasons. First and foremost, rinsing can help reduce the fat content of the meat. If you’re trying to cut down on calories or simply want a leaner dish, giving your ground beef a quick rinse under hot water might be the trick.

Rinsing can also help eliminate excess grease, preventing your dish from turning into an oily mess. Imagine a perfect plate of spaghetti, where the star of the show isn’t overshadowed by a pool of unwanted fat. Rinsing can be the hero that sаvеs your meal from becoming a greasy catastrophe.

On the flip side, many cooks argue that rinsing ground beef is a culinary sin. One of the primary concerns is flavor loss. When you rinse ground beef, you risk washing away not only the fat but also some of the savory juices that make your dish delicious. After all, who wants a bland and dry burger when you were aiming for a flavor explosion?

Another point against rinsing is that it can be a messy affair. Picture yourself at the sink, trying to juggle a pound of ground beef while hot water splashes around. It’s not the most glamorous part of cooking, and the cleanup might not be worth the potential benefits.

While rinsing fat from ground beef down the sink might seem likе a convenient solution, it can lead to serious plumbing issues. As the fat cools, it solidifies and can clog pipes over time. This creates a recipe for disaster, potentially causing blockages, slow drainage, and even the need for costly plumbing repairs.

Dispose of fat from ground beef by letting it cool and solidify, then scrape it into a sealable container. Toss the container in the trash, preventing plumbing issues caused by pouring fat down the sink. Proper disposal ensures a smooth-running kitchen and avoids potential pipe blockages.

So, should you rinse your ground beef? The answer depends on your culinary goals and personal preferences, but our short answer is no. If you’re a flavor enthusiast who wants every drop of deliciousness, skipping the rinse is the way to go.

Whether you’re Team Rinse or Team No-Rinse, the most important thing is to enjoy the process of creating mouthwatering meals. In the end, the choice is yours.
