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.

Jacques Dubochet, Joachim Frank, and Richard Henderson have claimed the 2017 Nobel Prize in Chemistry for their development of cryo-electron microscopy. ↓↓More info and references below↓↓ This year’s winners surprised many people and stirred up the perennial “is this really chemistry?” debate. But the Nobel committee (and the president of the American Chemical Society, Allison Campbell) believes that cryo-EM’s development is firmly entrenched in the central science. Check out our explainer behind the work that’s enabling researchers to image large biomolecules with atomic precision, ushering in a new era of biochemistry. And there was at least one person whom this pick did not surprise. Shout out to Gurunath Ramanathan, a viewer of C&EN’s Nobel Prediction Webinar who submitted this guess: “Cryoelectron microscopy is changing the way in biology.

As a result, a supernova will occur, and a huge amount of energy will be ejected into space. It will be brighter that the light from a majority of stars in the galaxy. The consequences will be visible to the naked eye from the earth's surface. It will take place in 2022.

How chemists help keep tabs on nuclear materials — Speaking of Chemistry
 
05:55
The same materials that give a nuclear weapon its unique destructive power can also be used in peaceful power generation. So how can international regulators ensure nuclear materials are used only for peaceful purposes? ↓↓More info and references below↓↓ Chemists around the country are helping develop techniques to spot illicit nuclear activity from afar and track it when it slips out of regulatory control. For example, massive antineutrino detector called Watchman could be a powerful tool to keep tabs on nuclear operations—if scientists can get the chemistry right. Note: This video was updated on 5/16/18 to correct the chemical symbol for plutonium. Special thanks to Cameron Tracy, Patrick Huber, and Patrick Feng for sharing their time and knowledge.

Cassini’s legacy: Titan’s bonkers atmospheric chemistry—Speaking of Chemistry
 
08:43
Cassini’s mission to the Saturn system is coming to an end, but the space probe has uncovered chemical mysteries on the moon Titan that will keep scientists busy for years to come. ↓↓More info and references below↓↓ When the Cassini space probe launched 20 years ago, planetary scientists knew that Saturn’s moon Titan showcased some complex atmospheric chemistry. But now that Cassini has had a closer look at the moon, researchers are shocked just by just how gnarly that chemistry is. In this episode of Speaking of Chemistry, we teamed up with Eos reporter JoAnna Wendel to learn how studying Titan’s atmosphere is teaching us more about our solar system and even our home planet.

Genetically Modified Humans? CRISPR/Cas 9 Explained
 
03:57
This week Reactions dives into your DNA with the science and chemistry behind CRISPR/Cas 9. Fans of Blade Runner have already caught a glimpse of world with super-powered humans secretly living among us, capable of physical feats far beyond your everyday person. But now, with the the CRISPR/CAS9 Gene editing system, are we looking at a future with real replicants? Check out this video to get an inside look at how CRISPR works, and the sorts of wild medical advances that are on the horizon.
