During the first year of being in a romance, a protein in our cells called Nerve Growth Factor (NGF) that is vital for the functions of particular sympathetic and sensory nerve cells, appears to thrive. During youthful love, our senses are heightened, and our fight or flight reaction system is activated.

Polar bears are heavyweight, and in them, male polar bears weigh more than female polar bears. Male polar bears are twice the size of female polar bears and can weigh up to 800kg. In addition to this, male polar bears can measure up to 3 meters long and are the largest land carnivore globally.

You may or may not be aware that love can result in strong infatuation. The same serotonin levels reported in persons with obsessive-compulsive disorder, an anxiety disorder, are found in those with infatuation. This is most likely why you can't seem to think of anyone else while you're in love.

It doesn't seem to matter what others say about a new lover—in our eyes, he or she is always ideal. This blindness is essential for us to progress in our relationship. It is frequently required to progress to the "attachment stage," as scientists refer to it so that they can stay in love long enough to produce and raise children; in other words, to populate the globe.

Dopamine, a neurotransmitter released during the beginning stage of a relationship, is also triggered when cocaine and nicotine are used. It provides the surge of pleasure and euphoria that makes those narcotics so addictive. It also increases the secretion of testosterone, which, as previously indicated, is necessary for attraction. If you were to choose between the three, we believe falling in love is the safer option.

DNA or deoxyribonucleic acid of a species plays an important role in its identity. And in the case of polar bears, scientists have discovered a new innovative technique to find out the DNA of polar bears. They can get to know about the DNA of a polar bear by its footprint on the snow. Isn't this interesting?

Mother hens teach their chicks not to ingest potentially harmful grains, where to obtain food, and how to forage. Chickens also mimic one other's actions; as chicken keepers are well aware, they will all do it if you can get one chicken to do anything you want.

Snacking on that yummy leftover just before bed may not be a good idea if you want to sleep well and peacefully. According to this study, eating close to bedtime might have a detrimental impact on sleep efficiency, particularly in women. Furthermore, another study shows that ingesting dairy products before bedtime is more likely to result in unsettling and unusual dreams than other forms of food.

Our smartphones may be an important part of our everyday lives. Still, this handy technology may be hiding a not-so-great surprise after all. A study of mobile phones used by secondary school pupils found that they were significantly infected with potentially dangerous germs. According to experts, cell phones, in fact, contain 10 times more germs than most toilet seats.

Although there are around 25 billion chickens in the world today, more traditional or "heritage" breeds are increasingly in danger of becoming extinct. This is because industrialized chicken farming (and now factory farming) bred in attributes to improve meat and egg output while paying little attention to retaining the original breed features. It's notfunfun' fact, but it's vital to know.

We are a part of the cosmos, and scientific study backs up this claim. Aside from hydrogen, which is big bang dust, all other elements in our bodies are made of stardust. After completing the math, this would imply that 97 percent of our bodies are made out of stardust.

With all that our brains have to deal with daily, it is understandable that they may want a well-deserved vacation from time to time. Blinking, thankfully, comes to the rescue around 15 to 20 times each minute. According to one research, that brief sleep period allows the brain to power down and take a mental break for a split second before resuming focus. As a result, experts believe that we blink more when performing a task that involves greater mental effort since our brain requires more rest the more we stress it.

Chickens (and all birds) are true dinosaurs since one lineage of dinosaurs survived the cataclysmic extinction 65 million years ago, the birds. Chickens descended from dinosaurs and are the closest surviving related to the mighty Tyrannosaurus rex. On the other hand, Chickens are the most prehistoric and 'dinosaur-like of all of our current birds. You can see a velociraptor just by watching them run and some of the sounds they make (I'm looking at you, broody hen).

We've all experienced the uplift and mood-altering effects that music can have on us, but its power doesn't end there. According to one research, a good song may physically speak to the heart. The heartbeat was discovered to synchronize with the musical rhythm. In fact, researchers discovered that crescendo choices caused a rise in blood pressure, pulse rate, and breathing. On the other hand, these measures decreased during decrescendos and quiet intervals.

The ocean continues to be one of the most enigmatic and perplexing things to humanity. No matter how much we learn and tell about it, there is still much more to learn and reveal since we have only explored one-fifth of it. With a total volume of 1.35 billion cubic kilometers, it is safe to assume that we have a long way to go before we can unravel the endless mysteries that this mystery may be hiding.

We may not anticipate it, but what we wear directly impacts why mosquitoes won't leave us alone. These little insects are drawn to dark colors because, according to this study, black attracts more mosquitos than white. According to the same study, these flying insects are drawn to heat, which dark colors absorb more than bright hues.

With hundreds of millions of neurons interacting in a gigantic network of more than a trillion connections, there is little question that this intriguing organ possesses superhuman potential. According to one research, our brain's memory amounts to 2.5 million GBs, which is equivalent to storing 3 million hours of television.

Trees may have more to them than meets the eye. Their roots are thought to be interwoven underground, forming a massive network that may be visually likened to the human nervous system. This network, according to experts, allows trees to communicate and aids in their behavior, defense, learning, and memory.

Like humans and other mammals, Chickens go through a REM (rapid eye movement) phase of sleep, which is associated with dreaming. However, they have another sleep phase that humans do not, known as USWS, in which one half of the brain sleeps while the other half is awake. Chickens can sleep with one eye open, an evolutionary adaptation that allows them to watch for predators as they sleep.

Chocolate bars were not the first chocolate treat, but hot chocolate was. And that hot chocolate was nothing like we get today. It was just a bitter concoction that was often enjoyed during weddings and other occasions. Isn't this interesting?.

We are always told that chocolate causes tooth decay, but it actually prevents tooth decay. The antibacterial agents in the cocoa beans inhibit the growth of the cavity-causing bacteria in the mouth and prevent tooth decay. But yes! This doesn't give you the right to eat chocolates daily

In 1905, Frank Epperson, an 11-year-old boy, left soda powder and water outside overnight with the wooden stirrer still in the cup. The concoction had frozen due to the cold evening temperatures, and so the Popsicle was created. He marketed the dessert in his neighborhood and at a neighboring amusement park, and he even copyrighted the recipe. Years later, he changed the name to Popsicle since his children referred to their father's concoction. And if you like these strange facts, don't miss these 18 history courses your instructor lied to you about.

We are well aware of the teeth of the sharks. Sharks have several rows of teeth & have the capability of losing and replacing the teeth so many times in their lifetime. Sharks, as predators play an important role in the health of marine ecosystems- by eating the fishes, sharks maintain the food chain.

We, human beings, are generally aware of the 5 senses that we all possess. But have you ever thought about sharks? Sharks have a sixth sense too. The sharks' sixth sense helps them hone in ok prey during the final phase of an attack. On shark's snouts, the ampullae of Lorenzini is found that can sense the electric field emitted by the other animals in the water.

Although the now-retro rainbow design is undoubtedly Apple's most well-known, the very first Apple logo depicted Sir Isaac Newton seated under a tree with an apple ready to fall on his head. The Newton logo was created by Apple's lesser-known creator Ronald Wayne and was only used briefly in 1976. Its high degree of detail didn't show up well when scaled down and put on a device.
