When you think about sharks, you probably picture a mouth full of razor-sharp teeth tearing away at your body limb by limb. Thanks to amazingly awful shark horror movies, people generally share a deep fear of the creatures. While there have been various incidents of real-life shark attacks throughout history, sharks are not the natural man-eaters people imagine them to be. In fact, scientists agree that you're more likely to be killed by a coconut than by a shark. For example, without sharks, the oceans would be riddled with dead aquatic life or overpopulated with fast-breeding schools of fish. This is because <a href="https://rumble.com/v34sx2-going-to-hammerhead-shark-school.html" target="_blank">sharks</a> will often feast on carcasses and consume exploding sea life populations, which helps to keep the oceans clean, healthy, and balanced. Did you know that some sharks can live up to 200 years? These amazing creatures have existed for over 400 million years. That’s longer than trees! They survived through an incredible 4 mass extinction events. Their eternal ears can detect a sound up to 1 km away, and over the course of a lifetime, sharks can grow around 30,000 teeth. Sharks hunt like no others. They can detect one drop of blood in 2.5 million litres of water, while small nodules can detect electrical pulses from beating hearts. <a href="https://rumble.com/v3kokj-spectacular-slow-motion-footage-of-great-white-sharks.html" target="_blank">Some sharks</a> can emit light from special skin organs know as photophores, and use it for camouflage, and to attract mates. Parthenogenesis has also been reported in some sharks. This is when females give birth without male fertilization. Sharks kill an average of five people per year, while humans kill up to 100 million sharks per year. As sharks are apex predators, slaughtering them in such high numbers could be disastrous to fisheries, coral reefs and ocean ecosystems around the world.

When you use cannabis, it can temporarily alter the way your brain works.

The Earth is really, really old. Over 4 1/2 billion years old, in fact. How do we begin to comprehend a number that large? It helps to put it on a more fathomable scale. Watch to see where Earth's major events would fall on a timeline. Everything humans have ever experienced - art, science, language, technology - happened in a tiny fraction of <a href="https://rumble.com/v4bj75-nasa-history-earth-from-space-a-view-from-the-space-shuttle-1994.html" target="_blank">Earth’s history</a>. Life has an incredible amount to teach us about living well on planet Earth, in no small part due to the fact that it’s been thriving here for a very long time. But, how long is that really? And where do we fit in to that history? Where do we fit on Earth’s timeline? Earth was “born” on January 1, 4.54 billion years ago. If we compress 4.54 billion years into one year, that means 144 years is 1 second. Life appeared 3.8 billion years ago. On the geologic calendar, that makes February 25 Life’s birthday. Life first appeared as simple cells, which thrived for millions of years before photosynthesis evolved 3.6 billion years ago. That would make <a href="https://rumble.com/v4vest-new-catalyst-catches-the-sun-by-improving-artificial-photosynthesis.html" target="_blank">photosyntheis’s</a> birthday March 21. 1.5 billion years ago multicellular life emerges, 650 million years ago planet earth freezes, 470 million years ago land plants start to grow, 300 million years ago first land vertebrates emerge. The list is infinitely long and stretches on and on. There’s no guarantee that we, or any of the other species around us, will remain. We are all subject to the laws of natural selection. But we are surrounded by success stories that we can consciously emulate. We’re surrounded by species that have adapted and evolved to create conditions conducive to future generations of their own species, and others.

There is an equation that could help us figure out what the odds are that there is life on other planets.

There are some abilities that humans can only dream of having, but looking to the animal kingdom gives us a different story. Comic and movies aren’t the only place to find <a href="https://rumble.com/v4g3l7-s1-ep14-amazing-animal-superpowers.html" target="_blank">superpowers</a>. So far, superheroes are only fictional. But some of their powers already exist in the world, possessed by a whole range of <a href="https://rumble.com/v4ktjt-top-10-unbelievably-scary-looking-animals.html" target="_blank">strange species</a>. Some creatures have even more amazing, surprising, weird, funny or disgusting powers than any superhero. Sure, some animals can leap the equivalent of a tall building in a single bound. But others have ultra-strong faces, crazy loud voices, toxic blood, the ability to devour virtually anything, and indestructibility. Can you guess what the penis bug's superpower is? Take a look at some heroes and villains in the animal kingdom because they exhibit truly awesome superpowers. Some vipers and boas can detect infrared light, so their prey can run but they certainly can’t hide. The power of a mantis shrimp’s punch can generate bubbles that burst with a lethal temperature hotter than the surface of the sun. Ants have been known to lift up to 100x their own weight, however, rhinoceros beetles can potentially hold up to 850 x theirs. Electric eels can stun their prey with around 800 volts of electricity produced by electrocytes in their body. Starfish can regrow missing limbs if they lose one, but the missing limbs can also grow new starfish, too. The shocking pink dragon millipede engages in chemical warfare by producing cyanide to defend itself against attackers. Turritopsis jellyfish have learned the secret of immortality, and have the ability to completely rejuvenate their cells.

When shopping in the produce section of your grocery store, you’re probably used to seeing red tomatoes and green cucumbers, yellow bananas and purple eggplants. Just like animals - which have changed a lot since humans started breeding them for food - fruits and vegetables have undergone drastic transformations since humans became agriculturally focused.The fruit and veg that graces our plates today would have been unrecognizable to our ancestors. For thousands of years, humans were hunters and gatherers, which means they hunted animals and gathered wild plants for sustenance. As communities grew larger and more established, however, humans learned that it was more efficient to centralize the cultivation of food. Some plants were very different before humans came along and domesticated them, usually to make them more edible. Some of the fruit and vegetables we eat today were very different before humans got involved. We changed <a href="https://rumble.com/v42j5b-boost-your-energy-with-bananas.html" target="_blank">bananas</a> from stubby little fruits with hard seeds into long, easy to peel tubes of deliciousness. Eggplants, which actually used to look more like eggs became bigger with a sexy new shape. Carrots started off as little more than roots until we decided to turn most of them into tiny orange rocket ships. Watermelons were once small, bitter and tough to crack but now they are massive green chambers of juicy red goodness. Corn was just a dinky little plant with a few hard seeds that became one of the most important <a href="https://rumble.com/v31s8l-champagne-crops-saved-by-old-school-workers.html" target="_blank">crops</a> in human history. Watch the video to see side-by-side comparisons of wild produce versus what we see in the store today!

This is a great way to make life out of death, and preserve the memories of people who are no longer with us. Parting from one’s dearly beloved is a difficult task, albeit a fact of life. But thanks to someone’s forward thinking, you can now keep your loved ones close to your heart, thanks to this innovative solution that turns their cremated ashes into a tree. The concept of “life after life” comes from the company “Bios”. When their Bio Urn debuted in 2013, the idea was nothing short of outlandish. During cremation, the body is stripped of all organic matter, with the heat of the furnace stripping it all into vapor. What is left is ash from pulverized bone which contains zero nutrients and its pH can be harmful to seeds. The innovation in the Bio Urn comes in the biodegradable material and the two chambers that separate the ashes from the seeds during the plant’s gestation period. The bottom chamber holds the ash, while the top contains coconut shell and vermiculite, a mineral that helps plants retain water. When the root system grows strong enough—generally after a week—water will dissolve the top of the second chamber, allowing the roots and minerals to mix with human ash. But many people living in the cities don’t have a garden, so the company now came up with a solution that will help these folks grow their tree. The Bios Incube comes with a sensor that detects the needs of the soil inside the Incube, measuring humidity and temperature and providing a unique watering system and sends all that data to your smartphone. The hope that with their <a href="https://rumble.com/v4jcin-now-thats-a-cat-scan-zoo-uses-pioneering-technology-to-perform-a-cat-scan-o.html" target="_blank">technology</a> they can make this difficult period easier and provide comfort for families and friends.
