    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…

    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.…

    What does a Web Hosting Server look like?

    In this quick video, I’m going to show you what a server looks like. The unit of measure of servers is their thickness. This is a 2 u server – 2 units. One u is about a pizza box and this server’s about 2 u’s and you’ve got 3 u’s. 4 u’s is probably about your PC’s width. So you have dozens of these, hundreds of these in racks that look like little closets and you slide them on the rails inside the rack. For example, this is how you can take the harddrive out of a server. And so, if you have a RAID 5 server with 3 hard…

    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.

    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…

    This Is the End of the Silicon Chip, Here’s What’s Next

    Electronics keep getting smaller, and it’s all thanks to electric switches called transistors. When these little fellas replaced vacuum tubes, computers went from the size of entire rooms to merely the corner of a room. In the 60-odd years since, transistors have kept shrinking, scaling down and powering up our electronics with them. But many think we are hitting a choke point… what if we can’t make anything smaller?! Transistors have 3 terminals, a source, a drain, and a gate. Current flows from the source and, if the gate allows the electrons to pass, out the drain. You know how computer code is ones and zeros at its most fundamental…
