Nowadays, it is so easy to get caught up with what’s going wrong in the world that we forget to focus on what’s going right. We should all pay more attention to shed light on new medical advancements, artificial intelligence updates, archaeological discoveries, and space explorations, because they are so cool to know about!

5.New Medical Robots
There’s nothing new about using a robot to perform surgery, as they’ve been helping to assist doctors for years. But even newer robotic advancements have helped in the medical field this year. Among one of them was the invention of the first ever ingestible robot. It’s fashioned out of a magnet and pig intestines, which is sort of gross; but according to LiveScience.com, it can be used to “remove a battery, or other foreign object from a person’s stomach lining”.
4.Dino Diamond
This may seem hard to believe, but a remain of an actual one hundred million year old dinosaur tail was found recently in Burma. Apparently, it was about to be made into a piece of jewelry. It definitely would have been more valuable to scientists than any diamond necklace. It was a tail of a coelurosaur found in an amber deposit. As a result, scientists now know that amber deposits are the place to look for any more valuable dino remains. If further explored, we can gain new insight
to the extinction of the dinosaurs, and what may have caused it.
3.Agile Robots
This robot gives us a glance into the no-frills party of robotic design. It appears to have forgotten to put on it’s clothes this morning. Robots that can walk over different terrains or robots than can jump high seem like something out of Pixar movie. They can do more for human civilization and safety than you think . The Salto robot has the ability to jump over three feet into the air, and from there it can use an object to jump even higher. It was developed at the Ron Fearing’s Biomimetic Lab at UC Berkeley and it was modeled after the jumping habits of African bushbabies. When used to help humans, it could be an incredible tool that could look through rubble for survivors if a disaster were to happen.
2.Chimeras
Of course, all of the mythical hybrids mentioned on this list have been only mythological, but first successful human-animal experiments have finally happened just this year. The controversial topic of growing human organs inside of animals has never fully been an issue, because scientists were not quite able to figure out how to do it and did not have the funding from the US government. Private donors finally made human-animal research a possibility for scientists at the Salk Institute. But the experiments have nothing to do with any sinister plans to create human- animal monsters. Instead, they are using animal bodies to grow human organs so that patients who are on the list for an organ transplant will have a better and faster chance of receiving one. According to National Geographic news, “Every ten minutes, a person is added to the national waiting list for organ transplants”. This medical revolution is called a “chimera: an organism that contains cells from two different species”. Now that is amazing.
Feeling smart yet? If not, just keep browsing the web for new discoveries in science. It will keep you entertained for hours, and it’s way more productive that posting selfies on Instagram. But before we get to number one, here are a few comments from today. Looking good! Thanks for watching.
1,Space Discovery
Do you ever think about the galaxy and it’s infinite proportions? It took ALbert Einstein ten years to craft his famous “relativity theory” using a complex mathematical equations called tensor calculus. Calculus is hard enough to understand, but tensor calculus is on a whole other level. Einstein refined and sharpened the principal of gravity, suggesting it was a “space-time” theoretical matter. Rather, humans and the objects we use are “a consequence of a distortion in space and time”. Henceforth, the entire reasoning for the orbiting planets of the solar system can be attributed to the movement and momentum of the larger objects that offset the inertia of the other, smaller planets. These massive objects that are great enough to accelerate the entire galaxy into motion are black holes. A billion years ago, two black holes collided to release the energy of “a billion, trillion suns”, releasing gravitational waves. Until 2016, scientists and physicists finally detected a gravitational wave using super sensitive sensors in Louisiana and . This is huge for the study of astronomy, because not only can we see our galaxy through advanced telescopes , we can listen to it as well. And even more recently, gravitational waves of two “competing black holes” have been found. Lets just hope they are far, far away.
