Global Warming

We’ve all heard a thing or two about global warming. Scientists have been predicting the effects of fossil fuels and burning coal on the rising temperatures. But did you know they’ve done this for over 100 years? We can’t help but recognize that we, humans, are the cause of the rising temperatures, considering we’re the ones burning fossil fuels. We’re also the ones using single-use plastic and causing oil spillages across the entire planet. An issue of Popular Mechanics magazine from 1912 said, “the furnaces of the world are now burning about 2,000,000,000 tons of coal a year. When this is burned, uniting with oxygen, it adds about 7,000,000,000 tons of carbon dioxide to the atmosphere yearly. This tends to make the air a more effective blanket for the earth and raise its temperature.

The effect may be considerable in a few centuries.” Only one century later, the increase was more than we could imagine. It’s happening at a rate faster than we can believe. Smithsonian Mag reports that “2016 was the hottest year since the National Oceanic and Atmospheric Administration (NOAA) started recording global temperature 139 years ago. The effects of this global change include more frequent and destructive wildfires, more common droughts, accelerating polar ice melt, and increased storm surges.

California is burning, Venice is flooding, urban heat deaths are on the rise, and countless coastal and island communities face an existential crisis—not to mention the ecological havoc wreaked by climate change, stifling the planet’s ability to pull carbon back out of the atmosphere.” That’s a disastrous thing to read about, but it’s, unfortunately, the reality of our situation. Still, it remains one of those scientific mysteries we’ll never be able to figure out. Just what will happen when the world gets too hot? Is there a strategic way to stop it or slow it down? (Smithsonian Mag).

Cosmic Acceleration

We’ve read about dark matter, but what about dark energy? Even though it sounds the same, it’s quite different from each other. The only similarity is that both confuse scientists and remain one of the biggest scientific mysteries in the world. Basically, with dark energy, something in space is continuously expanding at an ever-increasing rate. But only recently have scientists possibly figured out what it is.

Science News reports that “it’s the never-changing density of energy residing throughout all of space, referred to by Einstein as the “cosmical term” and now called the cosmological constant.” However, they’re unsure of how large the cosmological constant should be. It’s much more than the difference between the size of the universe and a proton. Because of this, its identity remains a mystery. Scientists have yet to discover the cosmological constant (Science News).

Intelligent Alien Life

As we’ve already mentioned on this list, alien life must exist elsewhere, right? There must be some distant world where aliens are speaking to each other and plotting their takeover of planet Earth. That is if they even know we exist. In fact, according to Science News, there are already projects underway that are trying to discover life in other solar systems. They said, “projects like SETI have been listening for some such message, so far unsuccessfully.

There are two possible explanations. One, there have been no messages (perhaps the aliens are experts at game theory and calculated that contacting humans would be a bad strategy). Two, the messages are there, but nobody knows how to detect or recognize them.” At least they’re trying. That’s more effort than previously done. It remains one of those scientific mysteries that researchers want to discover. Let’s hope they’ll pick something up in our lifetime, otherwise, we’ll never know if there are truly aliens out there or not. Or maybe they’re already on our planet, living right next to us (Science News).

Time

Truthfully, one of the biggest scientific mysteries of humankind is time. Even though it seems straightforward, it’s more complex than that. It’s funny because scientists need more time to study time. But that’s the conundrum. Until they can figure out how to manipulate time, they’ll just have to keep on studying it.

Many questions arise regarding time, and that’s questions as, is time illusory or real? Does time always move forward, or can we manipulate time and make it more backward? Is time travel possible, and could we go into the future and go back into the past? Or must we always stay in the present? We may never get the answers to any of these and will just need to keep on living in the present moment (Science News).

The Ocean’s Twilight Zone

We’re not talking about the show The Twilight Zone from the 1950s, we’re talking about the layer of the ocean called the Twilight Zone. As you dive deeper into the ocean, less sunlight shines through the surface until you reach a depth of 200 meters.

The sunlight fades almost completely, and you’re left in eery darkness that scientists have had trouble studying. Andone Lavery, who works at the Woods Hole Oceanographic Institution told Vox,” “it’s almost easier to define it by what we don’t know than what we do know.” It remains one of the biggest scientific mysteries, but scientists assume that more fish are living in the twilight zone than in the regular ocean. They even assume that these creatures play a large role in climate regulation (Vox).

The Color Of Dinosaurs

Paleontology had its revolution when scientists got their first look at the colors of dinosaurs. Because no human was alive during this period, it’s always been a question of what these massive mammals looked like. They remain one of the biggest scientific mysteries out there. It was discovered by an analysis of melanosomes, which are organelles that contain pigments, in the fossilized feathers of Sinosauropteryz. This dinosaur lived in China more than 120 million years ago. After the discovery, it was found that the prehistoric creature had “reddish-brown tones” and stripes along its tail. Shortly after, a full-body reconstruction revealed the colors of a small feathered dinosaur that lived some 160 million years ago, Anchiornis,” reports Smithsonian Mag.

Through studying fossilized pigments, scientists have discovered more strategies about the dinosaurs’ countershading and camouflage. Furthermore, it was discovered that “in 2017, a remarkably well-preserved armored dinosaur which lived about 110 million years ago, Borealopelta, was found to have reddish-brown tones to help blend into the environment.” These discoveries are slowly shaping the way for humanity and helping scientists discover more about our past (Smithsonian Mag).

Editing Genes

In the early 1950s, scientists discovered the double-helix structure of DNA. Since then, scientists have thought about the possibility of artificially modifying DNA to change the functions of the organism. It was first trialed in 1990, when “a four-year-old girl had her white blood cells removed, augmented with the genes that produce an enzyme called adenosine deaminase (ADA), and then reinjected into her body to treat ADA deficiency, a genetic condition that hampers the immune system’s ability to fight disease,” reports Smithsonian Mag.

If we can edit genes, there’s a host of discoveries that will help the future. Furthermore, “the patient’s body began producing the ADA enzyme. But new white blood cells with the corrected gene were not produced, and she had to continue receiving injections.” This is pretty remarkable and opened a ton of new doors for researchers and scientists. They might be able to discover diseases like cancer by modifying the cells and reinjecting them into the body (Smithsonian Mag).

Why Do We Have Butts?

Everyone has a butt. The butt is the butt of all jokes. We could go on and on forever with butt jokes, but why do we have them? The truth of the matter is that butts remain one of the biggest scientific mysteries out there, even if it does seem hilarious. The appearance of the anus was a huge momentous moment in the evolution of animals. Before we had an anus, animals had to both eat and excrete through the same hole.

That doesn’t sound pleasant at all and sounds horrifying and repulsive. That sounds like one way to catch an illness and fast. Scientists are unaware of which animal first developed the anus, and when they developed it. Because the anus doesn’t fossilize, it’s impossible to dig through skeletal bones and fossils and find out where it first came from. Until we solve that mystery, we just have to be thankful for it (Vox).

Human Genome

Learning about the past and where humans came from is one of the biggest scientific mysteries in the world. We weren’t there to study them. In 2010, scientists used a tool to study the past. They “used a hair preserved in permafrost to sequence the genome of a man who lived some 4,000 years ago in what is now Greenland.” It’s fascinating that hair can survive a long time. He says, the hair revealed “the physical traits and even the blood type of a member of one of the first cultures to settle in that part of the world,” according to Smithsonian Mag. This is fascinating, considering how much information they were able to discover from just hair.

Because of this finding, geneticists and anthropologists were able to learn more about the culture of the past than they were previously. Still, it’s challenging to extract ancient DNA like hair or skin. Oftentimes, it’s contaminated with the DNA of microbes from the environment, which taints any findings the scientists might have made. To fight this, scientists also used the petrous bone of the skull, which is a dense bone near the ear to learn more about our ancestors (Smithsonian Mag).

Scavenger Beetles

Some insects and animals can walk on water, and that’s spiders, lizards, ants, and snails. Scavenger Beetles can also walk on water, but they can also do more tricks than just walk. They’re remarkable in that they can flip upside-down and scuttle beneath the surface of the water. It’s as if they’re climbing underneath a glass table, except that glass is water. It’s truly bizarre and is something that remains one of the most fascinating mysteries in regard to insects. To study this, scientists took a few different approaches. “In the first study to analyze this skill in-depth, researchers filmed the insects’ inverted crawling technique. These beetles trap air bubbles with their leg hairs to keep them oxygenated. But video footage shows this behavior may also keep them afloat and pinned to the surface.”

It seems like these insects are smarter than us humans. “The bubble likely gives the bug enough support to put some pressure on the water-air boundary without breaking through. The beetle’s footsteps even push up “tiny hills” of water along the surface as they go.” Even after observing these bugs, scientists still have many questions. They’re using these insects to help build bots that replicate the bug’s skills. This is just like the shark intestines and butterfly wings. It looks like scientists are turning to the natural world more and more to create an unnatural world for the use of search and rescue or military purposes (Smithsonian Mag).

Tardigrades

These aquatic extremophiles look like eight-legged chunky bears. They can survive in some of the most inhospitable places in the world. This includes extremely hot, boiling, hydrothermal vents, and absolute zero temperatures going from one extreme to the next. That’s not something humans will ever think about surviving, ever. They can survive the vacuum of space and pressure six times the deepest pit of the ocean. They’re also the only soft-bodied animal that can walk, compared to their counterparts that slither, wriggle, and thrash around like worms. Smithsonian Mag found out that “tardigrades walk like insects 500,000 times their size.

These little creatures look like aliens. They’re a bit freaky to look at, but we honestly have a lot to learn from them. Though they move only half of their already-minuscule body length (0.5 millimeters) per second on average, they can move two body lengths simultaneously at top speed. Slow as they may be, they also seem to adjust their steps according to the terrain they’re navigating.” Scientists are looking at ways to use the way they walk in new forms of locomotion, used for micro-scale robots. Again, we’re seeing the scientific mysteries in the world. The Tardigrades use minimal brain power and energy, following simple rules that have a high impact (Smithsonian Mag).
