    Can a Hot Drink Cool You Down?

    [♪ INTRO] When the heat of summer sets in, people flock to the beaches or head to the mountains to cool off. But in some arid parts of the world, on hot, dry days, people cool off by drinking hot beverages. Which doesn’t make a lot of sense, if you’ve never heard of the practice. If a cup of hot cocoa on a cold, snowy day makes you feel warmer, how could a hot drink also make you feel cooler? But there’s evidence to back up this age-old tradition, if the conditions are just right. In a study published in 2012, subjects exercised on a stationary bike. And they drank…

    Bitcoin: How Cryptocurrencies Work

    Say there’s a coin that’s currently worth hundreds of U.S. dollars, but it’s not made of gold, or platinum, or any precious metal. In fact, it’s not the kind of coin you can hold in your hand or stick in a piggy bank. It’s a digital currency, which means it only exists electronically. I’m talking about bitcoin. Bitcoin doesn’t work like most money. It isn’t attached to a state or government, so it doesn’t have a central issuing authority or regulatory body. Basically, that means there’s no organization deciding when to make more bitcoins, figuring out how many to produce, keeping track of where they are, or investigating fraud. So…

    How Close Are We to Building a Moon Base?

    The moon is the closest celestial body to Earth. Humans have been gazing up at it for our entire existence, finally landing on its surface in the 1960s. We’ve walked on the moon, carried out science experiments on the moon, we’ve even driven a car, hit golf balls and briefly grew cotton on the moon. So, the obvious next question is, when are we going to start living on the moon? For decades pop culture has been teasing us with lunar colonies, military bases, space hotels and more, but in order to populate the moon, or other planets, we may need to start small. So, how close are we to…

    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…

    5 Delightful Color-Changing Minerals

    Thanks to Generation Genius for sponsoring this episode of SciShow. Go to generationgenius.com and check out their next-generation science videos for grades K through five. [♪ INTRO ] From the bedrock that supports buildings, to the bones that let us dance the night away, minerals are pretty amazing. And with their rainbow of colors, they also add some sparkle to our lives. Normally, individual minerals are one color, that’s not always the case. Some look multi-colored upon a single glance, and others look different depending on whether you’re looking at them in the sun or under incandescent light. Some minerals even look different if you rotate them. When you do,…

    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…

    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…

    This Parasitic Plant Stole Over 100 Genes From Other Plants | SciShow News

    This episode of SciShow News is supported by NordVPN. Head over to nordVPN.com/SciShow to learn more about virtual private networks and internet security. [♪ INTRO] Plants might seem kind of dull and boring, but they are full of intrigue. And two new papers published this week showed just how manipulative and cunning they can be. The first, published in Nature Plants, found that parasitic dodder plants from the genus Cuscuta have stolen dozens of genes from their hosts. And they don’t just take genes — they use them too. You see, dodders are parasitic plants that don’t have chlorophyll—the pigment which captures light energy during photosynthesis. That means they can’t…

    Why Scurvy Shouldn’t Exist

    Thanks to Brilliant for supporting this whole week of SciShow. Go to Brilliant.org/SciShow to learn more. [♪ INTRO] When you hear the word “scurvy,” you probably think of jokes about pirates, but this disease can actually be really serious. Its symptoms include bleeding gums; bumpy, rashy skin; and joint pain, and if it’s not treated, it can be deadly. It’s not just a thing of the past, either. Scurvy still shows up in developing nations, and dozens of cases were reported in the United States in the last decade. Thankfully, it is relatively easy to treat — all you need is a high dose of Vitamin C. But here’s the…
