    The James Webb Space Telescope Is Delayed (Again)! What Is Happening?

    The James Webb Space Telescope being developed by NASA is set to be one the most exciting space observatories ever developed!, with totally novel technologies and instruments that will give us new insights into our universe. But unfortunately, its completion and launch has been delayed. Again. What’s goin’ on? The initial completion window for the James Webb Space Telescope, or JWST, was supposed to be between 2007 and 2011. There were some pretty severe budget and schedule issues, resulting in a 2011 overhaul of the project that set a new completion date for October of 2018. That turned out to be a little too optimistic, so they pushed it back…

    Could a Particle Accelerator Destroy Earth?

    Advancing particle physics demands we build bigger and badder particle accelerators, but every time the conversation about the next ultra-mega-super collider comes up some stick in the mud announces that it could kill us and the whole universe… But will it? You probably fall into one or two camps on this subject. Either you’re like me and you think that smashing some protons into each other head on at near light speed is just going to create some pretty pictures and obliterated protons, or you think it’ll create some pretty pictures and obliterate the Earth. But the quantum world is weird and unintuitive, so let’s all put our assumptions aside…

    Will We Ever Time Travel? Scientists Say ‘No’ Based on This New Discovery

    So, this is probably what you think of when you picture an atom, right? The thing is, the central part of this model is just plain inaccurate. Scientists recently found the nucleus of some atoms don’t look like this at all, and it’s causing a ruckus because well, this newfound shape straight up shouldn’t exist. When you learned about atoms in school, you probably learned about a couple of different models– and one thing was likely always the same- the nucleus was spherical. But it turns out that might’ve been too simple. Atomic nuclei are made up of protons and neutrons that are held together by the Strong Nuclear Force…

    You’re Too Clean, and It’s Messing With Your Immune System

    Washing your hands may be the best way to keep from getting sick, but in some ways, DIRT does a body good. We’ve all been taught that dirt is bad for us. In my Grandmother’s house “Cleanliness was next to Godliness” and everything was scrubbed clean and disinfected, but now with new research on the superpowers of the microbiome it may be time to rethink our relationship with filth. You may think dirt and soil are interchangeable, (they are both a grainy collection of minerals, oils, water, and organic matter.) BUT soil stays in your backyard while dirt is what follows you back into your house. BOTH have microbes. Germ…

    Scientists Are Using Your Body’s Bacteria To Battle Cancer, Is It Working?

    The bacteria that live inside you shape who you are on a pretty fundamental level–from your psychology to your body type. But new research also indicates that the billions and even trillions of tiny creatures in your body play a major role in the way you react to medical treatments…making your microbial ecosystem a literal matter of life and death. Yeah, hi, it’s me, your favorite microbe geek here. As we discover more and more about how the bacteria inside us influence our lives and our health, we also discover more places where this relationship is really important–and one of these areas is cancer. Yup, it turns out that your…

    We’re STILL Not Saying It’s Aliens, But Tabby’s Star Is Getting Weirder

    KIC 8462852 probably sounds like a string of random letters and numbers to you but I’m willing to bet if you’ve watched this channel long enough, you’ve heard it before. It’s the name of a star, also known as Tabby’s Star, and it set the internet ablaze a couple years back when it dimmed in ways nobody could really explain, unless you pinned it on aliens building massive structures to power their civilization. Since then though we haven’t seen the star’s light fade, and so public interest in it did. But in April of 2017 light levels started dropping again, giving astronomers new clues to come up with new ideas.…

    This Fluoride Battery Could Mean Phone Batteries That Last a Week

    Lithium ion batteries changed our world by delivering us hours of energy in a small lightweight package. But ya know what, my phone battery only lasts a day and THAT’S NOT ENOUGH! I NEED MORE!!! Luckily, scientists are already on it, and have been working for decades on a new battery design that could could last up to 8 times longer, leaving lithium in the dust. Introducing: Fluoride batteries!! Okay, before you yell at me in the comments- NO these aren’t ready yet. You’re not going to be able to watch this video and then buy a fluoride battery online. Science is slow, everything takes time, BUT this is a…

    Guest Hosting at DNews

    Hi everyone, Dr. Ali Mattu here. Recently the awesome people at D News invited me to come over and make some science videos together! On TestTube Plus, Trace Dominguez and I explored how to overcome anxiety. I partnered with D News’s Julia Wilde to explain hair-pulling disorder. And I managed to squeeze in an episode on the psychology of sexting. Let me know what you think of the videos in the comments below and be sure to subscribe to D News for more science videos every day of the week.

    Quantum Computers Are Making Classical Ones Faster, Here’s How

    Quantum computers promise to one day dominate their classical counterparts like the computers we use today. But classical computers will not go gentle into that good night. They’re fighting inevitable quantum supremacy, and they’re using some tricks they’ve picked up thanks to quantum computers. You’re probably familiar with how classical computers work, information is broken up into bits, which are represented by 1s and 0s. Quantum computers, on the other hand, could leverage quantum phenomenon to make themselves exponentially more powerful. We’ve got a whole video here that explains the fundamentals. There are certain tasks that quantum computers would ideally be suited to. Things like predicting how a molecule in…

    Here’s What It Actually Takes to Be a NASA Astronaut

    When NASA started recruiting for its first astronaut class in 1959, it had no idea what it was looking for because it didn’t know what was going to happen to the human body in space. Basically the agency needed people used to flying dangerous missions in untested vehicles while giving real-time feedback to engineers… which pretty much narrowed the pool to test pilots. President Eisenhower stipulated that due to the potential top-secret nature of this endeavour, they should be in the military. And this led to the basic qualifications for the first batch of astronauts. Military pilots who’d graduated from a test pilot school holding a bachelor’s of engineering with…
