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 century. Louis 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.

What Happens to Your Nose When Death is Near? The Answer Will Shock You
Death is a topic that many people find mysterious and a bit scary. Throughout history, humans have tried to understand what happens at the end of life. Interestingly, some scientific studies suggest that our sense of smell might help us understand when death is approaching. It seems our nose can provide clues about when death might happen, both by detecting when someone else is nearing death and by losing our sense of smell, which can be a sign of our own health issues.
One interesting thing about our sense of smell is that it might be able to detect when someone else is near death. Many people have shared stories about noticing a particular smell before a loved one passed away. These experiences suggest that there might be a mysterious sixth sense connected to our sense of smell.
Several theories try to explain this interesting phenomenon. One idea is that as the body gets closer to death, it produces certain chemicals or odors that most people cannot smell, but some individuals with a stronger sense of smell can detect. Another theory suggests that our sense of smell is connected to subtle changes in our emotions, helping us sense the upcoming loss of someone we care about. It’s not that we consciously realize we are smelling death; instead, our sense of smell might alert us that it is near.
While there isn’t a lot of scientific proof on this topic, some intriguing studies have been done. For example, researchers at the University of Chicago found that animals like dogs and cats can detect chemical changes in people with specific medical conditions, such as cancer. Similarly, it seems that humans with a keen sense of smell might also sense when death is approaching. There are even stories of animals living in hospitals or care homes that can often predict when a patient is about to pass away.
As we learn more about the human body, we are uncovering new connections and insights into how different systems and senses work together. The sense of smell, often not given as much attention as sight or hearing, appears to play a significant role in predicting when death is near for others and in understanding our future health. More research is needed to confirm these interesting discoveries. Scientists are looking into the chemical changes that happen in the body before death, as well as how problems with the sense of smell might affect overall health and the risk of dying. With a better understanding, we might be able to create diagnostic tools that use our sense of smell, which could lead to timely and potentially life-saving treatments.
The idea that “the body knows when death is near, and it begins in your nose” is an intriguing subject for research. The ability to detect death in others through smell and the loss of smell as a sign of future health creates new opportunities for discovery in medicine and human biology. By studying and utilizing our sense of smell, we could gain important insights into life and death, which may help enhance our overall well-being.
