Cheetahs Cannot Roar But They Can Purr and Meow

Cheetahs are known to be the fastest land animal on the planet. They are capable of reaching around seventy miles per hour for a limited timeframe. The species does not often hit its top speed, especially for long. Thus, they average between forty to fifty miles per hour when hunting. While they are sprinters, cheetahs are still pretty large predatory cats. They are part of the big cat population that includes lions, tigers, jaguars, leopards, and panthers. All belonging to the Panthera genus.

All of those big cats are capable of roaring. This is due to a ligament within their voice box that has been stretched to create a large, sound-producing passage. That allows a wide range of pitch, thus allowing all of them to roar. Yet cheetahs do not have this stretched voice box, meaning they are unable to roar. For your average house cat, they have a fixed structure in their voice box that limits their sound range, allowing purring or meowing. Cheetahs have this fixed structure, just like your house cat.

There Are More Synapses In Your Brain Than Stars In The Milky Way Galaxy

While new stars seem to be discovered continuously in our Milky Way Galaxy, thus far the number is at roughly Two hundred billion known stars. Naturally, this is a lot of stars and it’s only our galaxy. Imagine the billions of other stars within other galaxies, especially those larger than ours. Two hundred billion stars is a huge number, but somehow we humans are able to top this number with our brain.

In just one human brain, there are more synapses or nerve connections, than stars in the Milky Way. Currently, neuroscientists are able to track these nerve connections pretty well. In a study on a three-year-old, neuroscientist researchers found nearly one quadrillion of these synapses. This is important because we actually have far more as a child than we do as adults. By the time you become an adult, you’ll have around five hundred trillion synapses. Which is still more than the stars in our galaxy.

Our Brains Do Not Recognize The Color Of Magenta

Magenta is an odd color. It seems our brain either does not like it or does not know how to recognize it. Seriously, this is one of the scientific facts that can keep you up at night. You might see magenta and claim you can see it just fine. Yet no one knows how to actually pin down what it truly looks like. You’ll see people claim it is purplish-red or reddish-purple a lot, while some claim it is purplish-pink. It is true that magenta sits between the red and blue color pallet.

Yet there is a reason you cannot pin down what it looks like. Magenta does not have a specific wavelength of light truly associated with it. This means it is usually defined as the opposite of green. Our brains literally look at this color and say, well…it’s not green. We know it’s not that, so we immediately begin to then assume it’s associated with anything we know lacks any source of green. Removing this, our brain now puts it within the red-to-blue color pallet system.

A Lost Nuclear Bomb Is Somewhere Off The Coast Of The State Of Georgia

Nuclear weapons are known for being extremely powerful. Dropping one has only happened a handful of times in world history, but one was dropped in the state of Georgia that never went off. This happened in February 1958 as an Air Force jet crashed into a B-47 bomber that happened to be carrying a 7,000-pound nuclear bomb. The pilot was worried the bomb might break loose from the damaged plane, so they dropped it into the water right outside Savannah, Georgia near Wassaw Sound.

Obviously, this was an important bomb so the Navy began immediately searching for it. They did this for several months but never recovered it. Both the pilot and the Air Force claim the bomb did not have any plutonium, but this was hard to believe from the start. In fact, the assistant to the Secretary of Defense said in Congressional testimony in 1966 that this was a “complete weapon.” He claimed it had a nuclear capsule that contained both plutonium and uranium. The Air Force claims today that heavy metal spreading is likely very low and the bomb should pose no hazard to Georgia residents.

Humans Share 50% Of Our DNA With Bananas

We know this particular fact is one of the scientific facts that is much harder to believe than most of the others we’ve gone over. Yet it is completely true that humans share around 50% of our DNA with the common banana. This breaks down to things that a lot of people do not think about. This involves things like how we share the same type of genes that code different stuff in our DNA, such as cell growth for example.

While that growth might now work the same as it does in our DNA, the fact that it occurs at all is important as it’s similar to humans. Basically, bananas have exact counterparts to things we see in our DNA in many areas. These counterparts are where we share DNA. Therefore, this fact should be written out as “bananas and humans share 50% of the same DNA makeup.” As this would come off easier. Though that is not as simplistic for people to grasp as the headline grabber above.

Sharks Predate Trees On Earth

You can check many of the habitable worlds NASA and other astronomers have found and you’ll likely see plant life upon them in some form. This does not mean other life types are present but we all assume any habitable world will have plants. This is because, on Earth, we’ve seen proof of them pretty much throughout all known life. There are even plant fossils that have been uncovered. Trees have been around, it seems, forever.

However, that is not the case at all. In fact, on Earth, we know most life began in the world’s oceans. Though microbial, life eventually began to come about. This led to the first tree eventually appearing on land 350 million years ago. Yet sharks are older than this by 50 million years. The first sharks showed up as far back as 400 million years ago. Being older than trees is an accomplishment very few creatures can claim. We have no idea why this was not discussed during “Shark Week.”

Scientists Who Work With Cockroaches Often Become Allergic To Preground Coffee

You’ve likely heard the concept that bugs are in a lot of what you eat without you knowing. While bugs and insects do this a lot with things like chocolate, they also infest other things too. Coffee beans get more cockroaches than anything else we know of today. Douglas Emlen, a notable entomologist, noted that cockroaches actually infest large piles of coffee beans on the regular. But here’s the weird part, those cockroaches are often just ground up in the coffee and never removed.

Scientific facts like that would be enough to freak out over, but it’s not over yet. It is too hard to eliminate the roaches completely, which is why the United States FDA allows a certain percentage of insect filth to be included in coffee, among other foods. Some scientific researchers who work with cockroaches go on to develop acute allergies to them. Due to this, they also become allergic to preground coffee among other things cockroaches are known to infest.

Antibiotics Do Not Get Rid Of Infections

We know what you’re thinking right now. These scientific facts have gone off the rails, it’s clear that antibiotics are given to help you get rid of an infection. Actually, no, they are not. While infections can be difficult to deal with, our body’s immune system can fight them off. However, what often kills people is the symptoms of an infection or even our own immune system. In fact, a fever is good to have up to a point because that means your body is fighting an infection or virus off.

Yet a fever can easily go over 100 degrees as your body fights something, which can then cause horrific problems in the body and especially the brain. Due to this, antibiotics come into play to help fight the symptoms. Our immune system now does not have to do this alone and can focus more on killing the infection. This is why doctors tell you to finish your antibiotics, because the more they are present, the more help they offer your immune system to kill an infection entirely.

Nintendo Was Founded In 1889

We all know about Nintendo these days, right? If you’re old enough to remember the Super Nintendo or Nintendo 64, your childhood was likely awesome. The company gave us the likes of Donkey Kong, Kirby, The Legend of Zelda, and obviously the infamous Mario. While they are now one of the biggest video game companies in the world, they did not randomly show up during the 1970s and start building video game systems. Nintendo was actually founded back in 1889.

Before they became the infamous video game giant they are today, this Japanese company sold card games. It was founded by Fusajiro Yamauchi in Kyoto, and they began manufacturing “Hanafuda” or flower cards immediately upon opening their doors for business. They’d go on to make western-style playing cards, such as what you’d see used for poker. In 1974, Nintendo developed an image-projection system, then employed 16mm film projectors in arcades. By 1975, they worked alongside Mitsubishi Electric to develop their first video game system.

Cumulus Clouds Weight 1.1 Million Pounds

Now we get to the scientific facts that might amaze you. Peggy LeMone is a Senior Scientist at the National Center for Atmospheric Research. When discussing the average cumulus cloud with Mental Floss in 2013, she claimed each of those nice fluffy things has a water density of half a gram per cubic meter. On top of that, these clouds also have a volume of one billion cubic meters. Clearly, this is a lot to calculate.

To properly calculate it, you will need to remember that the density and volume total will give us the weight. As you calculate the total water content, you’ll end up with 500,000,00 grams of water. That is based on the billion cubic meter volume and half a gram per cubic meter. Now, you will need to convert your total grams into pounds. This gives us a total of 1.1 million pounds for the average cumulus cloud. Of course, this is just an average and could be more or less depending on the size of the cloud.

Cleopatra Lived Closer To The Invention Of The iPhone Than The Pyramid Of Giza’s Formation

If there is anything people know about Egypt, it’s their infamous pyramids. While there are three major pyramids, it’s the Great Pyramid of Giza that stands out among them. It is the only member of the Ancient Great Wonders to still survive. This pyramid was built between 2550 B.C. to 2490 B.C. Which is quite a long time ago, nearly 5,000 years from this time in fact. The Egyptian monarchy shifted a bit over these centuries, but no one ever wanted to remove these pyramids.

The Ptolemy dynasty came to be in the late B.C. period after Alexander the Great died. Ptolemy the I was a major part of the Macedonian Armed Forces, so once Alex died he went on to conquer Egypt. That led all the way to Cleopatra, the last in this line and officially the last Pharoh of Egypt. She died around 30 B.C. while Apple released the first iPhone in 2007. This means she died 2037 years before the iPhone was released while she was not born until 2421 years after Giza was finished.

Heroin Was Given To Kids To Help Relieve Coughs

Ah yes, the Bayer Pharmaceutical Company. You might know them best today as the company that brought us Aspirin. Yet this was by no means their first major drug used to relieve pain and help a lot of other conditions. In fact, they are the people that invented and commercialized heroin. This occurred mostly during the 1890s and early 1900s. Bayer claimed it was useful for cough, cold, and pain problems. In fact, they specifically marketed heroin for children this entire time.

They did this all the way up to 1912! This was well after evidence proved heroin was a dangerous drug. Various reports of scientific studies found this problem, so Bayer knew better. By 1914, heroin became prescription-only within the United States but the FDA eventually banned it altogether by 1924. This is one of the scientific facts that really amaze us because Bayer clearly put its profits over people.

The Early Earth Was Purple, Not Blue

Living beings who live in galaxies lightyears away from us might very well be seeing an Earth very different from what we are seeing today. If you look at Earth from space, you’ll see a very blue planet. That is due to all the water you can see from our many oceans. However, early lifeforms on Earth generated metabolic energy from the sun using purple-pigmented molecules called retinal. It is assumed that this predates chlorophyll and photosynthesis. This would have given the Earth a distinctly purple color, rather than blue from space. Scientific facts like this always freak us out.

On other planets, the retinal could create a biosignature that absorbs green light just like the way vegetation on Earth absorbs red and blue light. Earth is known for its oxygen, but we did not always have a great amount of it. For the first few billion years, we had rich carbon dioxide and methane. Yet 2.4 million years ago, that changed as an abundance of free oxygen in our atmosphere rose massively. This is assumed to be caused by cyanobacteria, able to form photosynthesis, transformed by sunlight and carbon dioxide. That forms into metabolic energy that produces sugars to give fuel life as they knew it.

Harvard University Was Founded Before Calculus Was Invented

Harvard University is the oldest higher education center in the United States. Yet people do not really know how old this university really is. American colonization began very early on and by the 1600s, we were already seeing cities rising in the eastern United States. Harvard was established in 1636, yet calculus was not discovered or formed until 50 years after this. It seems crazy to think that a major mathematical breakthrough did not occur until after Harvard came to be.

This was formed by Gottfried Leibniz in 1684 via his “Nova Methodus” as well as Isaac Newton’s brilliant 1687 work called Principia. If that does not freak you out, the infamous European physicist, astronomer, and mathematician Galileo Galilei did not pass until 1642. Meaning Harvard was formed while he was still alive. Overall, to think that a higher education institution is older than a lot of the things it eventually taught is one of those scientific facts that absolutely amaze us.

The Wooly Mammoth Died 1,000 Years After The Pyramid Of Giza Was Completely Built

It was widely assumed that the Wooly Mammoths died out during the late Pleistocene to early Holocene periods. They would have existed alongside the sabertooth tiger among others. In fact, we know that humans came across both over 10,000 years ago due to cave drawings uncovered in multiple sectors. The assumption was that either human beings hunted the Mammoths to extinction or they died out after a little ice age. Of course, that ice age would not have been as impactful as the previous.

In any case, these assumptions were wrong. Mammoths ended up surviving on a small area called Wrangel Island. This is now part of Russia. We also found that they survived on islands around Alaska and other Russian territories. The coolest part is that they ended up surviving until around 1650 B.C. That puts them surviving over 1,000 years after the Pyramid of Giza was completely built. Scientific facts like this one can be mind-blowing. Mammoths living well into human history? That’s amazing!

Bananas Are Berries But Strawberries Are Not

You might be wondering about this one heavily. Perhaps, you’re even assuming the “scientific facts” here are completely faked for amusement. Yet this article is about things that sound untrue but are actually a reality. In this case, we now know that bananas are technically berries but strawberries are not. Why is this, you might wonder? Botanists are to blame, but technically these two fruits are also not innocent in this ordeal either.

In botany, we know true berries are simple fruits with a stem from one single flower with one single ovary. They also tend to have several seeds. That means things like kiwis, eggplants, and bananas all count as “true berries.” However, strawberries come from the stem of a single flower…but they have more than one ovary. This makes them technically aggregate fruits along with their cousins, raspberries and blackberries. This is all weird, but completely true.

You Are Literally A New Person Every Seven Years

Whenever you hear that basic chick say “new year, new me” on her social media, she’s usually lying. We know she is not going to change her ways. Do you hear…or see this, Rachel? We have scientific facts to support this! However, she is not too far off honestly. You may already know that most dust you see in an average home is made up of our dead skin cells. We do not shed all of our cells like a snake sheds its outer skin, but we do something similar to this.

Our body sheds cells throughout the body all the time. While dust might be what you see when our skin cells fall off in favor of new ones, our inner cells are shed through things like the blood and exit our bodies when we use the bathroom and sometimes when we bleed. Every seven years, our body has shed every single cell it has from the start of that seven-year mark. Thus, every seven years, you are literally a new person. Biologically speaking at least. But this is not anything to freak out over.
