10 Extinct Animals Scientists Are Ready to Bring Back
 
10:09
Do you know that scientists are almost ready to bring back some species that have been long gone? A T-Rex and other dangerous creatures aren't on the VIP list, so we won't see them in the not-so-distant future. But some of our most beloved characters from the Ice Age movies can be brought back to life! Instead of using the controversial term “cloning,” scientists prefer to say “make un-extinct.” To-may-to, to-mah-to, the idea is the same. An animal that died out thousands of years ago can't be brought back to life unless it's cloned. And therein lies the problem. For successful cloning, scientists need to have almost completely undamaged animal DNA. That's why some species are more likely to be resurrected than others. TIMESTAMPS: The woolly mammoth 2:01 The saber-toothed tiger 3:00 The Moa 3:48 The ground sloth 4:27 The dodo 5:19 Woolly rhinoceros 6:12 The Irish elk 6:44 The Baiji river dolphin 7:26 The Siberian unicorn 8:05 The Neanderthal 8:55 Music: https://www.youtube.com/audiolibrary/music SUMMARY: - While most of the woolly mammoths died out about 10,000 years ago, there was a population of about 500 to 1,000 of them living on Wrangel Island as recent as 1650 B.C.E. The woolly mammoth was roughly the size of an African elephant. - The saber-toothed tiger was about the size of your typical modern-day big cats. It weighed from 200 to 600 pounds and could get up to 13 feet long. The saber-toothed tiger usually had a muscular neck, bobbed tail, powerful front legs, and dagger-like teeth that protruded from the upper jaw and could grow just under a foot long! - The moa was a huge flightless bird that looked kinda like an ostrich, minus the wings. We know of about 10 members of the moa family. Some were no bigger than a turkey while others reached a height of 10 feet, making this bird the largest that has ever inhabited our planet. - Ground sloths are likely to be successfully resurrected since they were still walking the Earth about 8,000 years ago. Even better, some samples of their DNA have already been received from undamaged hairs of this animal. - The dodo became extinct just 80 years after it had been discovered. Its only known habitat was Mauritius Island, where the dodo had been living peacefully for who knows how long until the Dutch showed up in the 1590s. - Besides the woolly mammoth, there’s one more fluffy extinct creature, the woolly rhinoceros, that scientists want to bring back. This animal still lived in the Arctic snows pretty recently, about 10,000 years ago. This furry rhino is quite famous too; it often makes an appearance in ancient cave art, like in the French Chauvet-Pont-d'Arc Cave. - The Irish elk, also called the giant deer, was one more animal that didn't quite manage to survive the Ice Age. This creature mostly died out about 12,000 years ago. But researchers have discovered Irish elk fossils in Siberia that are only 7,000 to 8,000 years old. - The Baiji river dolphin went extinct in 2006, making it the first cetacean (that’s whales, dolphins, and porpoises) to die out directly due to the negative impact of human activity. It's obvious by now that since the extinction is quite recent, there’s a sea of DNA samples at hand that make resurrection pretty much a guaranteed success. - A Siberian unicorn skull discovered in Kazakhstan proved that the animal had actually disappeared just 29,000 years ago. That’s good news for people who wanna see a real unicorn someday! - Bringing the Neanderthal back would be the easiest task of them all. Scientists already have a map of its genome. It’s not a question of whether or not we can, but if we should… Subscribe to Bright Side : https://goo.gl/rQTJZz ---------------------------------------------------------------------------------------- Our Social Media: Facebook: https://www.facebook.com/brightside/ Instagram: https://www.instagram.com/brightgram/ 5-Minute Crafts Youtube: https://www.goo.gl/8JVmuC ---------------------------------------------------------------------------------------- For more videos and articles visit: http://www.brightside.me/

10 Unique Animals You Won’t Believe Exist
 
09:42
10 strange and amazing animals that you have probably never heard of. Nature is truly full of surprises! We live in the twenty-first century, and all continents have already been discovered, all secrets of our planet revealed, all mountain peaks conquered. Just when you think you have seen it all, some new bizarre creature makes an appearance instantly restoring your faith in the impossible! TIMESTAMPS Mangalitsa Pig, a.k.a. “a pig in sheep’s clothing” 0:50 Rhinopithecus or golden snub-nosed monkey 1:33 Emperor tamarin 2:13 Patagonian Mara 3:04 Fluffy cow 3:52 Markhor Goat 4:44 Raccoon dog 5:23 Blue Footed Booby 6:25 Malayan Colugo 7:13 Venezuelan Poodle Moth 8:09 BONUS 8:56 SUMMARY - The birthplace of this curly-haired pig is Hungary where it was discovered in the mid-19th century. Due to the fleece covering this animal, it resembles a sheep, therefore, such a name! - The name of this species is roxellana, and there is a story behind it. It is believed that they were called this way after the supposedly snub-nosed courtesan of Suleiman the Magnificent (a 16th century Sultan of the Ottoman Empire). - They were called like this because of the resemblance of their mustache to that of German Emperor Wilhelm II. - Patagonia Mara is the fourth largest rodent on our planet. There are several interesting facts about them. Females often put offsprings into crèches for safety. - Fluffy cows are looked after by people whose work is to wash, dry and use products to style these animals, so they look as fluffy as they do! It is necessary to maintain them daily, and it will take months of regular grooming until they get this lovely look of kids toys. - If you see a creature which looks as if it’s trying to catch an alien radio signal from space, it’s most likely Markhor Goat. They can grow as long as 6 ft from head to tail! - If you can’t decide if you want to have a dog or a raccoon as a pet, we have just the thing for you - raccoon dog! Despite having raccoon-like markings on their fur, they are not very closely related to the North American raccoon. - Blue Footed Booby are to catch your eye if you ever visit the Galapagos Islands. They can look a bit clumsy and comical on land, but they are excellent at flying and swimming. - Colugo has a large gliding membrane (like a flying squirrel), and they can glide for long distances between trees standing far apart. - Even if the Poodle Moth may look as if it lives in Antarctica with all this fur, in fact, it comes from Venezuela, a tropical country. Its hairs don’t serve for heating. BONUS Cloud Antelope! This species lives in the clouds (that’s why such a name)! Its bright blue fur is the reflection of cloudless blue skies in the area of its habitat. Its diet consists of sun rays and candies...

Who Lives In the Deepest Place On Earth?
 
09:57
Who lives at the bottom of the Mariana trench? Scientists have finally revealed the Mariana Trench mystery. Take a look at the deepest creature ever caught there! The curiosity of human nature makes people look for secrets and mysteries far away from home, like in outer space or on other planets. Scientists have mapped only 5 percent of our planet’s seafloor. And if you’ve ever considered the ocean plain and boring, the video you’re about to watch will blow your mind. TIMESTAMPS The Mariana Trench is the deepest area 0:45 The deepest-living fish in the world 2:40 “Ethereal snailfish” 3:12 A mysterious metallic sound 3:38 Deep sea cucumber 5:50 The deep sea anglerfish 6:20 The barreleye fish 7:13 The Champagne Vent 8:05 The 4-inch amoeba 8:35 SUMMARY The Mariana Trench is the deepest area you can find on Earth. Although almost everybody has heard the name, we have shockingly little data about this dark underwater place in the western Pacific Ocean. It’s a monumental task mapping the seafloor and taking pictures when the water pressure at the bottom is more than 1,000 times greater than that at the surface!

17 Scientific Facts That Seem Too Crazy to Be True
 
07:48
We have put together a list of the most fantastic and unbelievable scientific facts that seem too crazy to be true. This world will never stop surprising us, just take a look for yourself! Scientists have recently found that the universe tastes like raspberries and the Mona Lisa actually used to have eyebrows. The coldest place in the Universe isn’t on the Moon, where temperatures can plunge down to minus 378°F. It was recorded in a lab, where scientists in Finland managed to freeze atoms using a laser. If we could get rid of the empty space in atoms, all of humanity would fit into an apple. The biggest living organism in the world is a mushroom. Human lungs have the same surface area as a tennis court. Whether a man has a son or a daughter can often depend on what kind of siblings he has. You might have heard that a person is usually a bit taller in the morning than they are in the evening. As for the height of the Eiffel Tower, it changes depending on the weather. The cavefish can walk and climb thanks to its tetrapod-like pelvis. It uses its flippers like four-legged land animals use their limbs. your brain helps you stay fit! Assuming that the average metabolic rate during rest periods is 1,300 calories, your brain takes 260 of them! Thumbnail: Cryptotora thamicola.

Its jumps are 3.14 inches per millisecond. -If just one person’s lungs were opened flat and put on the ground, they would completely cover an area as big as a tennis court. -Men inherit from their parents the tendency to have more daughters or more sons. -Archerfish can recognize people's faces with over 80% accuracy. -The height of the Eiffel Tower changes depending on the weather. In the summer heat, it can get 5.9 inches taller. -Part of the static noise you hear on an empty channel is a trace of the Big Bang. -The cavefish can walk and climb thanks to its tetrapod-like pelvis. -Mona Lisa used to have eyebrows and eyelashes. -Male chimpanzees have best friends because it helps decrease their stress level during conflicts. -The brain needs as much energy as a 10-watt light bulb. -Three cups of coffee a day can cause breasts to become smaller, especially if they were big to begin with.

9 Mysterious Places That Leave Scientists Confused
 
09:08
The history of the world is full of surprising mysteries. None of us will live long enough to see them all solved. Scientists have already discovered a lot about the Universe, but there are some real places out there that even leave them completely baffled! Have you ever heard, for example, about boiling river or never-ending lightning storm? Other videos you might like: It Takes Hundreds of Lives a Year, But Only 5% Know About It https://www.youtube.com/watch?v=n9IFaBH2vdk& A New Bermuda Triangle Theory Explains Its Mystery https://www.youtube.com/watch?v=6SWMb4Oh5jY& 4 Mystery Doors That Should Never Be Opened https://www.youtube.com/watch?v=xfYnUaLpdc0& TIMESTAMPS: Blood Falls 0:24 Floating Islands 1:12 Fiery Gates 1:59 Never-ending Lightning Storm 2:55 Boiling River 3:52 Split Sea 4:42 Twin Town 5:29 Sleeping City 6:22 The Petrifying Well 7:30 Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY: - For a very long time, scientists couldn’t figure out what the reason was behind this crimson fall. At first, they believed that red algae gave the water its gory tint. But new studies found that iron oxides are present in the water. - Despite these islands constantly moving, locals build their huts on them because most people in the area earn money by fishing in the lake. - In the hot Karakum Desert in Turkmenistan, there’s a 226-foot-wide hole that’s been on fire for almost 50 years! - If “lightning never strikes the same place twice” then apparently this unique spot in Venezuela where the Catatumbo River meets Lake Maracaibo didn’t get the memo. Here, there’s an average of 260 storm days and about 1.2 million lightning bolts striking it a year. - Located deep in the Peruvian Amazon, this 4-mile-long river known as Shanay-Timpishka gets as hot as 196°F, which obviously means no swimming if you don’t wanna become soup! - The devastating flood that hit Kerala, India last year almost submerged the whole state underwater. But then the locals saw a narrow strip of sand that had surfaced from the water along the beach and literally split the sea into two. - While the national average of twin births is no more than 9 in 1,000, the number is as high as 45 in 1,000 in Kodinhi. - Speaking of mysterious villages, this real-life and literal sleepy hollow is the remote town of Kalachi in Kazakhstan. In 2013, locals couldn’t stop falling asleep while they were doing everyday activities. - This mystical well is located near the River Nidd, which runs through Knaresborough in North Yorkshire, UK. Oh yeah, and its water is known for turning objects into stone!

Scientists Have Found Plastic-Eating Bacteria
 
09:37
How to solve the plastic pollution problem? Bacteria that munch on plastic: could this be the answer to the humanity’s environmental crisis? After all, we’re drowning in tons of plastic, and it’s hurting our oceans, the creatures in them, and even our own health! This microscopic plastic-eater isn’t your average bacteria. Scientists actually found a way to mutate this microorganism and boost its planet-saving superpower. It can make the world a better place by eating away all the plastic waste. And with about 20,000 water bottles being bought every second around the world, it’s got a big job to do. TIMESTAMPS: What plastic-eater is 0:52 How much plastic end up in our oceans every year 1:41 How long it takes for plastics to biodegrade 4:03 What it all started with 4:37 Enzyme technology 6:55 How you can reduce your use of plastic 7:14 #plasticeatingbacteria #pollution #savetheplanet Music by Epidemic Sound https://www.epidemicsound.com/ SUMMARY: - A staggering 19 billion pounds of plastic end up in our oceans every year. Once it’s there, it gets ingested by the animals that humans eat, which means our health gets affected too. - Plastic can disrupt ecosystems and create more and more areas where nothing can survive. - Plastic is all around us, and (get this) it’s even inside of us! Plastic is used so extensively that it’s been found in human stool! - It takes around 400 years for some types of plastic to fully biodegrade, like the ones used in water and soda bottles. - Japanese researchers discovered a strand of bacteria that’s evolved to eat a particular type of plastic called polyethylene terephthalate, commonly known as PET or PETE. - According to them, the bacteria could break the plastic down into smaller pieces but not fully eat it away. It took about 6 weeks for the bacteria to eat through a thin layer of plastic. - Enzyme technology could be used to help humanity’s trash problem, but it’s still in its early stages. The researchers are continuing to tweak the enzyme in hopes that they can improve upon it even further and use it on a larger scale. - The creation of this super enzyme is a great way to kick off a solution to plastic pollution. But this enzyme, despite its mutant nature, can’t undo all the pollution that’s currently in the world. - As long as people keep buying and using it, companies will continue to manufacture plastic. The cycle will keep on going until the consumer is willing to break it. - Don’t give into the lazy convenience of plastic plates and utensils. Use porcelain dinnerware, and just do the dishes afterwards. Just make it fun and turn on some music or your favorite show!

10 Shockingly Large Creatures That Actually Exist
 
07:00
These massive animals and creatures will give you nightmares! Subscribe to our channel: http://goo.gl/9CwQhg Compared to the size of the Earth, humans are pretty darn small. It’s just a fact of life that we already know, but we don’t necessarily “see” it until we are next to something so much bigger than us. Regardless of whether you believe in a creator, in evolution, or both, humans and animals were created to be a certain size for a reason. So when we encounter a creature that is so large that it shocks you to the core, the world definitely takes notice. When it’s an animal that is supposed to be smaller, it’s even more shocking. Scientists then desperately want to intervene and they want to know more about how this animal could have grown to such large proportions. Was it because of genetics? Nuclear waster? An anomaly in the animal kingdom? These creatures certainly prove that we still have a lot to learn about the world around us. In this video are ten shockingly large creatures that actually exist. From creatures that were meant to be small, to creatures that are out of this world in their size, we have to wonder whether or not bigger is always better? Some of these creatures were intentionally modified to grow to their incredible size while others have genetics and Mother Nature to thank! You could even consider some of these creatures as additional wonders to the world. While we would like to think that we know everything about the world around us, we have only skimmed the surface.

7 Mysterious Discoveries Scientists Can't Explain
 
12:22
There are amazing discoveries that made the smartest scientists scratch their heads for years. These experts spend their whole lives searching for answers to some of the world’s biggest mysteries. Yet some of their findings defy logic and are still waiting to be solved. TIMESTAMPS: The Maine Penny 1:20 Gold Spirals 2:49 Alaska Artifact 3:59 Rujm el-Hiri 5:14 Mohenjo-Daro 5:56 Longyou Caves 8:51 Swimming Reindeer 1:23 #mysteriousdiscoveries #amazingdiscoveries Music by Epidemic Sound  https://www.epidemicsound.com/ SUMMARY: - The coin was made between 1605 and 1093 during the reign of King Olaf III. But how did a silver Norse coin, the only Norse artifact discovered at the site, travel all the way to Maine? - Flemming and other researchers assumed that these gold spirals were part of a priest-king’s costume or headwear, which would have been worn during ritual sun ceremonies. - The buckle-like object had been cast in a mold with a small leather ring attached to the bar, and it was about 2” by 1”. Thanks to its leather material, the researchers were able to estimate how old the object is through radiocarbon analysis: it’s 1,500 years old. - Rujim el-Hiri is another remnant of the Bronze Age, and it dates back to an estimated 3000 to 2700 BCE. The megalithic structure is located in Golan Heights and is made from approximately 44,000 tons of basalt stones. - Mohenjo-Daro can rival the greatness of ancient Rome, though it didn’t have a “central seat of government or evidence of a king or queen” according to a National Geographic article. - The Longyou Caves in Zhejiang province, China, aren’t your ordinary caves with cavernous passages, stalagmites, and stalactites. The 2,000-year-old man-made caves consist of 36 grottoes covering approximately 32,000 sq ft. - The Swimming Reindeer is made from the tip of a mammoth tusk that is 8” long. The sculptor possessed extraordinary creativity and skill: it was beautifully crafted with great detail using only stone tools.

15 Recent Science Discoveries You Wont Believe
 
08:39
15 amazing recent discoveries in the world of science and here they are from bionic contact lenses to reanimating dinosaur dna! Subscribe to Talltanic http://goo.gl/wgfvrr 7. New Human Species Biologists all over the world were intrigued upon hearing the 2015 discovery of a new species of human, Homo Naledi, allowing for an ever clearer picture of our ancient ancestry. The findings were unveiled deep in an underground cave in South Africa and is considered one of the greatest collection of human remains ever unearthed. So far, it is known that this species of human grew to an average height of 5 feet and had a brain no larger than an orange. The way the bones in the South African cave were arranged suggests that these human ancestors ritualistically buried their dead, giving scientists a glimpse into our cultural past. 6. Bionic Lens While still in the testing stage, the founder of Ocumetics Technology Corp may have stumbled upon a revolutionary technology that could augment the way humans perceive the world. A new bionic contact lens will give wearers an ability to see the world with stronger than 20/20 vision. Some subjects, who have already tried the lens themselves, claim that they not only see better than ever before but have identified a unique spectrum of colors unfamiliar to the unaided eye. Is this perhaps the first step in the direction of a new era of superhumans? 5. Harder Than Diamond Scientists may have recently discovered a substance harder than diamond, Q-carbon. What gives diamonds their excellent hardness are the chemical bonds that hold them together. The carbon in diamonds is held together by incredibly tight chemical bonds at the microscopic level, giving diamonds their prominent hardness. By the manipulation of carbon atoms, scientists were able to augment their chemical bonds, producing a material that is potentially 60 times harder than diamond. While this substance is still being experimented on, it is a potential prospect for the future of cheap, efficient technologies. 4. First Mammals Researchers from the University of Edinburgh have discovered an ancient species of mammals that survived the notorious extinction of the dinosaurs over 65 million years ago. The reason this find is so significant is that it gives us a glimpse at how mammals began to rule the world previously dominated by their cold-blooded counterparts. The mammal is thought to have been a plant-eater closely resembling a modern beaver. Once the dinosaurs were eliminated these beaver-like creatures began to flourish, given that they were no longer victims of dinosaur predators. Because these little guys were able to withstand the destruction that wrecked havoc on the dinosaurs, an array of mammals, including our ancestors, were finally able to leave their mark on the world. 3. Whale Gene Mapping Gene mapping is starting to look less like a theoretical nicety and more like an applied science with this new aquatic discovery. Scientists have finally discovered why Bowhead Whales are able to live to 200 years old by remapping their entire genome. By comparing the genome of Bowhead Whales with the genome of other mammals with a less impressive lifespan, scientists were able to point out marked differences. Bowhead longevity is due to its genes’ effectiveness in repairing gene deterioration, which is the cause of cancer and other ailments known to cut human life short. By further studying this animal’s genes, scientists may finally be able to restore our own faulty genetic system, substantially lengthening our lives. 2. Second Earth NASA has recently confirmed their discovery of a possible second Earth. Kepler-452b orbits its sun in what scientists call the “Goldilocks Zone,” which is the habitable region in space, not too far or close to the sun, necessary for the possibility of life to flourish. The new planet appears to have a rocky surface as well as liquid water, which is another key ingredient for life to subsist. Although not much is known about if there is life beyond Earth, it makes sense to take notice of planets similar to our own. 1. Animal Re-animation Scientists have always been intrigued by the prospect of re-animating creatures that have been extinct for many years. While bringing a dinosaur back to life would be kind of cool, bringing a Wooly Mammoth back to life would be just as cool, and that is just what scientists are trying to do. Because Wooly Mammoths and Saber-Toothed Tigers have only been extinct for tens of thousands of years, unlike the millions of years dinosaurs have been extinct, intact DNA samples are much easier to find. Scientists believe it is possible to recreate these extinct beasts by cloning them with DNA and tissue samples, which have been found, over the years, preserved in ice.

The surprising science of alpha males | Frans de Waal
 
15:55
In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.

When Insects First Flew
 
09:11
Insects were the first animals to ever develop the ability to fly, and, arguably, they did it the best.

10 Extinct Creatures That Could Have Ruined The World
 
14:56
Do you think that dinosaurs were kind of scary? Think again! In its time, evolution created creatures so terrifying they make dinosaurs look like cute little babies! So do you want to find out which creatures would've completely destroyed our world if they were alive today? Then let's get started! TIMESTAMPS: Liopleurodon 1:04 Arthropleura 2:15 Megalania 3:23 Dunkleosteus 4:47 Jaekelopterus 6:03 Sarcosuchus 7:03 Gorgonops 8:24 Titanoboa 9:40 Meganeuropsis 11:07 Helicoprion 12:28 #extinctanimals #extinctcreature #seacreatures Music: https://www.youtube.com/audiolibrary/music SUMMARY: - Liopleurodon was a giant marine reptile from the family of short-necked plesiosaurs. This species lived during the Callovian stage of the Middle Jurassic Period. The typical size of a Liopleurodon varied from 16 to 23 ft, but the largest reached over 33 ft. - Arthropleura lived in the territories of current northeastern North America and Scotland about 315 million years ago. The species ranged from almost one to 7 ft in length and were around 2 ft in width. Arthropleura's body was apparently composed of around 30 jointed segments covered by 2 side plates and one center plate. - Megalania is the biggest monitor lizard you can possibly imagine. The youngest of its fossils dates back to approximately 50,000 years ago. The length of the largest Megalanias reached around 23 ft with a maximum weight of 1,320–1,370 lb. They were unbelievably active hunters. - Dunkleosteus became extinct about 358–382 million years ago during the Late Devonian period. However, there wasn't just one Dunkleosteus — there were actually 10 species of it, including D. terrelli, D. denisonii, and D. magnificus. D. terrelli, the largest of them, was almost 20 ft long. Most Dunkleosteus fossils were found in North America, Poland, Belgium, and Morocco. - Jaekelopterus was a giant predatory sea scorpion Scientists confirmed that Jaekelopterus reached a size of nearly 8.5 ft, which makes it the largest arthropod ever. - Sarcosuchus, a distant relative of living crocodiles, lived about 112 million years ago. It had somewhat telescoped eyes and a long snout with 35 teeth on each side of its upper jaw and 31 teeth on each side of its lower one. - Gorgonopses lived around 260 million years ago, terrifying all the smaller species of that time. As for their size, these creatures were about 10 ft long and weighed nearly 1,000 lb. They were basically at the top of the food chain. - Titanoboa lived in the region that's now a part of northeastern Colombia, and its fossils date back to about 58–60 million years ago. Titanoboa holds the scary record for the largest snake ever discovered with a total length of nearly 48 ft and a weight of about 2,500 lb. - Meganeuropsis still continue to be the biggest insect of all time with a wing length of 13” and a body length of almost 17”. The very first fossils of Meganeuropsis were actually discovered in France back in 1880. - Helicoprion lived was around 290 million years ago, living in North America, Eastern Europe, Asia, and Australia's waters. The most distinctive feature of Helicoprion was its circular jaw. Helicoprions proved to be incredibly strong since they survived the Permian-Triassic Extinction Event that killed 90% of marine animals and around 70% of terrestrial ones.

With near constant revolutions in life, punctuated by catastrophic extinctions, it is also one of the most chaotic. Correction! At 9:19, we erroneously refer to Dimetrodon as an herbivore. It was definitely a carnivore. We even made a whole video about Dimetrodon and their carnivorous ways in a previous episode: https://youtu.be/SR3OOP9mImI Thanks to everyone who pointed out our error!
