Even though we all have it, we might not know much about the mysterious membrane in the corner of our eye. In fact, this tissue is the remnant of a third eyelid and is much more prominent in birds and some mammals to protect their eyes from dust. However, for us humans this membrane doesn’t actually serve a purpose and therefore it is believed that it will completely disappear over time.

We might not expect this, but what we are wearing can have a direct effect on why mosquitoes won’t leave us alone. These little insects are attracted to dark colors since, according to this study, the color black catches more mosquitoes than white. The same study also tells us that these flying insects are attracted by heat which dark colors absorb more than light ones.

We might consider our smartphones to be an indispensable part of our daily lives, but this useful device might be hiding a not-so-great surprise after all. A study on secondary school students’ mobile phones revealed that they were highly contaminated with potentially pathogenic bacteria. In fact, according to scientists, cell phones carry 10 times more bacteria than most toilet seats.

According to research, 99% of the Earth’s gold is buried in its core. If we somehow were able to dig out this massive amount, we would obtain a ginormous amount of this precious metal, enough to fully envelop the surface of our globe with a 4-meter thick layer of gold.

There might be more to trees than meets the eye. It is believed that their roots are interconnected underground in what forms a gigantic network that can be visually compared to the human nervous system. According to scientists, this network allows tree communication and helps with their behavior, defense, learning, and memory.

The fact that we are made of trillions of microorganisms might startle some. Actually, for each human cell, we have 10 microbes. However, there is no need to worry here. In fact, these microscopic living organisms help with the functioning of our body as they are necessary to digest food, regulate the immune system, protect us against other harmful bacteria, etc.

With hundreds of millions of neurons interconnecting with each other in what forms a colossal network of more than a trillion connections, there is no doubt that this fascinating organ has ultrapowerful capabilities. According to a study, the memory of our brain equals 2.5 million GBs which can be compared to holding 3 million hours of TV shows.

According to this Yale study, the Earth has 3 trillion trees. This would equal 420 trees for each living person. With all the wonderful benefits that trees have for the planet and for us humans, all we can say about this good news is that the more trees we have the better.

The ocean remains one of the most mysterious and bewildering things to us humans. No matter how much we uncover about it, there’s still so much to learn and reveal, since we have only explored a fifth of it. With its total volume of 1.35 billion cubic kilometers, it is safe to say that we still have a long way to go in order to uncover the infinite secrets that this enigma might be hiding.

Surprisingly, the reason that the nose and ears appear bigger with age is actually the sagging of the skin and the effect of gravity on it. This also happens to the other organs of the body, however, these 2 are the most visible ones.

Snacking on that tasty leftover right before bed might not be a great idea if you’re looking for a sound and peaceful slumber. According to this study, food intake close to bedtime can have a negative influence on sleep efficiency, especially for women. Moreover, another study suggests that consuming dairy products before bed can lead to disturbing and bizarre dreams, more than other types of food.

All living things on our planet, including us humans, evolved from the same origin according to science. This would be the Earth’s original ancestor, a 3.8-billion-year-old organism named LUCA (last universal common ancestor). After all, we’re all made of cells that have common traits like ribosomes and a genetic code that is believed to go back to this one single entity.

A brief moment of relaxation with the eyes completely shut never hurt anybody — on the contrary, it is believed that our memory can benefit from this brief pause. According to an experiment, 15 minutes of rest with the eyes closed after listening to a short story can help you remember the story better. Moreover, based on this study, it was found that eyewitnesses to crimes recalled more accurate details when they closed their eyes.

When we try visualizing the cosmos, dark shades of blue are most likely to pop into our minds as the dominating color. However, science tells us that this couldn’t be any further from the truth. Surprisingly, it turns out that the universe’s average color obtained as the resulting mix of the lights emitted by 200,000 galaxies, is beige. This color was defined as ’’cosmic latte’.’

We have all experienced the uplifting and mood-altering effect that music can have on us, however, its influence doesn’t stop there. According to a study, a good tune can speak to the heart, quite literally. It was found that the heartbeat synchronizes with the musical beat. As a matter of fact, researchers have found that selections with crescendos, led to an increase in blood pressure, heart rate, and respiration. And on the other flip side, these measurements came down during decrescendos and silent periods.

Science tells us that that the human eye is able to differentiate between approximately 10 million different colors. This might, at first, seem like an impressive amount, however when we think that a 24-bit monitor can display more than a whopping 16 million color combinations, we might start seeing things a bit differently.

We are part of the universe, and according to scientific research, this statement is quite literal. Aside from the hydrogen in our body which is big bang dust, all of the other elements come from stardust. After doing the calculations, this would mean that 97% of our body is made up of stardust.

These fruits might share their name with the actual color, but this doesn’t mean that all oranges are orange. As a matter of fact, oranges initially contain big amounts of chlorophyll which is the reason why this citrus is initially green-colored. As it matures, the chlorophyll dies off when they are exposed to cool temperatures and the color orange appears. This is the reason why in warmer parts of the world, oranges stay green.

With all the things our brains have to constantly process, it is fair to say that they might often need a much-deserved break. Thankfully blinking is here to the rescue about 15 to 20 times per minute. According to a study, that miniscule moment of shut-eye helps the brain to power down and go on a mental break for a split second before attention being restored once again. Therefore, according to scientists, we blink more when we are conducting a task that requires more mental activity since our brain would require more rest the more we stress it.
