What 2021 Scientific Discovery Excited You the Most?

Science is ever-evolving, and 2021 was rich in discoveries. From health to space, there were developments in diverse scientific areas bringing us knowledge and further understanding. In this slogging thread, our community shared their favorite scientific discoveries of the year. This Slogging thread by Mónica Freitas, Daniel Guzman, Sara Pinto, Amy Shah and Jack Boreham occurred in slogging's official #random channel, and has been edited for readability. Mónica Freitas Dec 6, 2021, 2:26 PM What's the 2021 scientific discovery that most excited you? Mónica Freitas Dec 6, 2021, 2:30 PM For me, it was a team from Northern Arizona University and Johns Hopkins University discovering that water was once present in a region of Mars called Arabia Terra. It can tell a lot of past environments and their evolution. 😮 2 Mónica Freitas Dec 6, 2021, 2:31 PM Limarc Ambalina, Sara Pinto, Jack Boreham, Khamisi Hamisi, Daniel Guzman, Teri Eyenike, Favour Amadi, Allyson Blinkhorn, Amy Shah: What was yours? Daniel Guzman Dec 6, 2021, 4:43 PM Hey Mónica Freitas! I heard a while ago that a group of astronomers identified a planet outside the Milky Way, using NASA's Chandra X-ray Observatory! We're one step closer to Aliens 👽, do you believe in Aliens? Mónica Freitas Dec 7, 2021, 12:40 PM Daniel Guzman, did we? Did we name it yet? I want to google it! I'm not narcissistic to the point of believing that we're so special that there are no other forms of life outside of earth. So, I do believe in Aliens. I'm not sure about the grey big-headed image we're often fed, but I'm sure there are other forms of life. There are so many hints of patterns that repeat themselves in the universe, so it's only logical to me that other living creatures also exist somewhere else. What about you? 👽 Sara Pinto Dec 8, 2021, 12:49 PM Mónica Freitas, I'm not sure if it's considered a discovery, but yesterday I saw in the news that we managed to get a quite detailed photo of the sun. Since I enjoy the visual side of the space discoveries, this, for me, was pretty amazing! https://www.news18.com/news/buzz/this-could-be-the-clearest-ever-photo-of-our-sun-have-you-seen-it-yet-4528412.html 🔥 1 Sara Pinto Dec 8, 2021, 12:56 PM Mónica Freitas, on the other hand, an actual discovery was finding the two black holes near Earth. These two might merge at some point, creating a massive black hole. I wonder what this means for us since black holes have a big gravitational and magnetic force. https://www.eso.org/public/news/eso2117/ Mónica Freitas Dec 8, 2021, 2:48 PM Sara Pinto, WOW, that picture is amazing! We've never been able to see beyond the gases around the sun. This is so clear! 💚 1 Mónica Freitas Dec 8, 2021, 2:51 PM Sara Pinto, I can see how that can be a massive deal for us. If their gravitational force is big enough, it can affect our solar system. It's a bit frightening. Sara Pinto Dec 8, 2021, 3:55 PM Mónica Freitas, it probably doesn't excite us, but it certainly leaves us alert! 🔥 1 Mónica Freitas Dec 16, 2021, 10:29 PM Sara Pinto, true that! On another news, a spacecraft has 'touched' the sun for the first time. I only found that out now, but it happened back in April. "NASA's Parker Solar Probe reached the sun's extended solar atmosphere, known as the corona, and spent five hours there. The spacecraft is the first to enter the outer boundaries of our sun." https://www.sciencedaily.com/releases/2021/12/211214134947.htm 🔥 1 Mónica Freitas Dec 16, 2021, 10:33 PM Also, there seem to be new developments around HIV. "An experimental HIV vaccine based on mRNA - the same platform technology used in two highly effective COVID-19 vaccines - shows promise in mice and non-human primates, according to scientists. Their results show that the novel vaccine was safe and prompted desired antibody and cellular immune responses against an HIV-like virus." This is very inspiring. https://www.sciencedaily.com/releases/2021/12/211209124236.htm Amy Shah Dec 17, 2021, 5:53 PM Not sure if this was in 2021, but I was pretty excited about the COVID vaccine as well as other treatments that have been developed to get us out of this pandemic. Amy Shah Dec 17, 2021, 5:54 PM Anything to get me out of the house and social again. Mónica Freitas Dec 20, 2021, 5:54 PM Amy Shah ABSOLUTELY!I will be even more excited when we get a cure for this disease and can resume our lives as before. Jack Boreham Dec 21, 2021, 10:51 AM https://www.sciencedaily.com/releases/2021/12/211214134947.htm Jack Boreham Dec 21, 2021, 10:51 AM This is pretty cool!! Mónica Freitas Dec 21, 2021, 5:05 PM Jack Boreham COPYCAT! I saw that article. It's awesome! I don't know how they were able of building something that could endure those high temperatures. Jack Boreham Dec 22, 2021, 12:26 PM Mónica Freitas, hahaha, great minds think alike. 🔥 1 Jack Boreham Dec 22, 2021, 12:26 PM Mónica Freitas, would you live in space if you got the chance? 😄 Mónica Freitas Dec 22, 2021, 2:18 PM Jack Boreham, ahahah let's blame it on our geniality. Mónica Freitas Dec 22, 2021, 2:18 PM Jack Boreham, actually, I've thought of that a lot growing up. So, here's my line of reasoning: I'd love to see the space for myself. However, I have a weak stomach that cannot handle the trip to the stratosphere - I'd be sick and nauseous throughout. The journey would take long, meaning I'd a chunk of my life on that trip. So, I'd a single trip to see one thing would be costly time-wise - imagine going young and fresh and returning with wrinkles already ahaha; Unless we're just talking about a short trip to the moon - then it's more doable. The food is terrible. In conclusion, yes, I'd love to go, as long as it was for free, I was knocked out during the flights, a month-long tops and I can take my snacks. Mónica Freitas Dec 22, 2021, 2:19 PM Jack Boreham, how about you? Sara Pinto do let us know your thoughts on this. Jack Boreham Dec 23, 2021, 12:36 AM 😂 Mónica Freitas, I completely agree with the knocked-out part. There's no way I would want to wait around, hoping nothing bad would happen. Hopefully, they will speed up the process. By that point, I hope the suits aren't as claustrophobic; otherwise, I'm going to die in space. I hate things that feel like they are going to suffocate me. Mónica Freitas Dec 23, 2021, 2:59 PM Jack Boreham, ahahah you must hate amusement parks. But I get it. I've tried those scuba diving things and panicked. Being stuck on a spaceship would be equally nerve-wracking 😂 Sara Pinto Dec 23, 2021, 4:18 PM Mónica Freitas, I'm a little late, but the news on "touching" the sun, that's (almost) literally fire 🔥😂 Sara Pinto Dec 23, 2021, 4:29 PM Mónica Freitas, I would like to go on vacation, for like 3 days. Actually, living there? I don't think so. The view would be amazing every time, but after a while, it's just you and space. Unless you are an enthusiast about it, I don't think it's that exciting. Sara Pinto Dec 23, 2021, 4:29 PM Mónica Freitas, when it comes to the journey there, in my naive head, I think I would actually like to be awake, haha. Mónica Freitas Dec 27, 2021, 3:32 PM Sara Pinto, oh yeah, I'm with you. I wouldn't be able to live in space, maybe if I were more of an introvert. Mónica Freitas Dec 27, 2021, 3:33 PM Sara Pinto, oof, you're braver than me
