- Animals That Do DrugsE1
Animals That Do DrugsTurns out humans aren't the only animals that can medicate themselves - many other animals have found ways to deal with illness by using natural remedies. Hank will tell you about some of the most interesting methods animals have found to heal themselves, and maybe get a little crazy in the process. - Space News From The Future!
E5Space News From The Future!Today Hank uses his patented prognosticating abilities to tell you about some space news events to watch out for in 2013. What one thing is the Curiosity rover going to spend most of the year doing? Why are we going back to the moon? And what two awesome things are projected to occur around Thanksgiving Day? Find out in this edition of SciShow News! - How Many Stars Are There?E9
How Many Stars Are There?ERROR IN VIDEO - There are up to 200 BILLION stars in our galaxy...not 200 million. How many stars are there in the universe? This question leads Hank to a couple other questions - How many stars can we see from Earth? How many stars are there in our galaxy? - but the answer to the original question proves elusive. - DNA and Dung Beetles
E12DNA and Dung BeetlesEmily Graslie of The Brain Scoop (http://www.youtube.com/thebrainscoop) stands in for Hank in this week's news to tell us about an effort to classify every organism on Earth, a fight amongst scientists about what happened in the 8th century, and a whole new look for your DNA. Oh, and some new information about dung beetles! Strap in for a ride through science! - SciShow Talk Show #1: Emily, Rhinos, and Cas the Arctic FoxE13
SciShow Talk Show #1: Emily, Rhinos, and Cas the Arctic FoxFeaturing Emily of The Brain Scoop (http://www.youtube.com/thebrainscoop) and Cas the Arctic Fox! We decided it would be cool to have guests come into the studio and talk about science with Hank. In our first episode, Emily Graslie chats about rhinoceros conservation and stumps Hank with a very peculiar bone from the Philip L. Wright Zoological Museum. Then Jessi from Animal Wonders introduces Cas the Arctic Fox...and he's the coolest thing that's ever peed on Hank's desk! - 3 Weird Ways Olde Tyme People Got HighE15
3 Weird Ways Olde Tyme People Got HighHumans have been processing plants for their narcotic effects for at least 5000 years, historically for ceremonial purposes, to deal with harsh environmental conditions or difficult situations, and sometimes even to supplement nutrient-poor diets. Michael tells you about some of the strange "natural" things our ancestors used to alter their minds, but he can't promise they're not going to be gross. - The Most Beautiful Science of 2012
E16The Most Beautiful Science of 2012Michael Aranda substitutes for Hank again in this week's News to tell you about the winners of the 2012 Visualization Challenge, an annual competition run by the journal Science that selects the most elegant and educational graphics, videos and games which show science in action. Science, meet art! - SciShow Talk Show #2: Peter, Self-healing Skin, & Professor Claw the Emperor ScorpionE17
SciShow Talk Show #2: Peter, Self-healing Skin, & Professor Claw the Emperor ScorpionFeaturing Peter Winkler, our SciShow graphics guru, and Professor Claw, the emperor scorpion. We decided it would be cool to have guests come into the studio and talk about science with Hank. In this episode, Peter and Hank discuss the science of prosthetic skin and Saturn's rings. Then Jessi from Animal Wonders introduces Professor Claw, the emperor scorpion and Hank debates how cool it is to get stung by a scorpion. - Fun With Potatoes & Physics! A SciShow ExperimentE20
Fun With Potatoes & Physics! A SciShow ExperimentHank uses a favorite subject of the YouTube community - the potato gun - to teach us about the principles of pneumatics, which use the potential energy of compressed gas to do work in lots of useful machines every day. - SciShow Talk Show #3: Katherine, Cats and a Brush-tailed BettongE21
SciShow Talk Show #3: Katherine, Cats and a Brush-tailed BettongFeaturing Katherine Green, Content and Social Media Manager for SciShow and also Hank's wife, and Quigley, the brush-tailed bettong or woylie. In this episode, Katherine shows Hank some cute wild cats, and then they meet Quigley and Jessi from Animal Wonders and talk about woylie conservation in Australia. - Big Idea: Blood TransfusionsE22
Big Idea: Blood TransfusionsThe idea of putting blood into a person was a radical one when it was first attempted 350 years ago, but today, more than 15 million pints of blood are donated each year in the U.S. to be used in transfusions to over 5 million patients. Hank tells you the strange story of how blood transfusions got their start in medicine. - Hank Meets a Giant Squid and Other News
E24Hank Meets a Giant Squid and Other NewsHank is back in the studio and is very excited to be able again to share news of the universe with you, including his encounter with a giant squid, an English king discovered under a parking lot, new pyramids discovered in Africa, and how the compound that makes Viagra work might also help you live longer. It's good to be back! - Weird Places: Göreme National ParkE26
Weird Places: Göreme National ParkThere are a lot of weird places on Earth and our new series will explore some of the weirdest. Today Hank takes us to Göreme National Park in Turkey so we can learn about this region's fascinating geological history and about the people who have been living there since the 4th century. - Spring, Time for Drunk BirdsE27
Spring, Time for Drunk BirdsAs spring approaches in the Northern Hemisphere, we anticipate the fluttering butterflies and the capering baby lambs, and we can also expect to see some birds hammered out of their minds in the trees, and perhaps on the ground. In most cases, these birds have overindulged in the fermented berries and other fruits that froze during the winter and are now thawing - proving an irresistible treat for many kinds of birds. - The Science of Genetically Modified FoodE28
The Science of Genetically Modified FoodIn the U.S., genetically modified organisms are everywhere, despite the fact that creating GMOs for food is incredibly expensive and time-consuming and their impacts on the environment and on human health are largely unknown. But even though a lot remains unexplained, there's still plenty you need to understand: what GMOs really are, how they're made, and what we do and don't know about them so far. Hank helps you get the facts straight. - Extreme Animal CannibalismE31
Extreme Animal CannibalismEvolution doesn't care about ethics - it cares about surviving and getting your alleles out there as much as possible. From that perspective, cannibalism can seem like a pretty good idea to some creatures. Hank introduces us to three different types of animal cannibalism, and tells us about some of the species that practice them. - Richard Feynman, The Great Explainer: Great MindsE33
Richard Feynman, The Great Explainer: Great MindsAside from being a great scientist and teacher, Richard Feynman was a kooky and curious guy who played the bongos, painted, and did math in strip clubs. Hank shares his Feynman love fest with us in this episode of SciShow: Great Minds. - Is There Gravity in Space?E34
Is There Gravity in Space?In a word, "yes" - space is packed with gravity. Hank explains how Isaac Newton described how gravity works, and why even though it seems that things are floating in space, they're still effected by gravity. Every object in the universe is constantly attracting every other object in the universe. - The Search for AntimatterE35
The Search for AntimatterIf you don't have any idea what antimatter is, you don't have to feel bad - the brightest minds in the world have only recently begun to understand what it is and how it works. Hank gives us the run down on what we know about antimatter, and what we're still trying to figure out. - The Manhattan ProjectE36
The Manhattan ProjectSome of the greatest advances in science have come from humanity's more destructive impulses. This is not the fault of science - when we discover powerful truths about the universe it's up to us to decide how to use them because they can either be boons or banes to the world. There may be no better example of this than the work done by the Manhattan Project - the years long, multinational effort to develop an atomic bomb during World War II. The project created unfathomably destructive weapons and led to a 50 year Cold War with the USSR, but is also the source of a lot of information about the atom we didn't have before, which has led to advances in many beneficial fields, like energy production and medicine. Science, like history, is always complicated. - Major Brain Dump!
E37Major Brain Dump!This week on SciShow news, strap in for a trip through the frontier of the human brain. The human connectome is a years long venture to explore and map the pathways of the human brain, and this past week scientists released two terabytes of awesome quality pictures in an enormous data dump which is now freely available to be used in all manner of neurology research. - Breaking News: Mars Suitable for Life
E38Breaking News: Mars Suitable for LifeEarlier today, mission specialists with NASA's Mars Science Laboratory announced that they have found, for the first time, evidence of an ancient environment on Mars that could have sustained life. Hank tells us the specifics in this very special, super-exciting episode of SciShow News. - Viking Sunstones and Mummy Health Secrets
E40Viking Sunstones and Mummy Health SecretsToday on SciShow news, dead person wisdom is helping enrich our understanding of the natural world - how did Vikings manage to be such awesome navigators? And is heart disease inherent in human beings? Scientists think mummies may have the answer. - IDTIMWYTIM: "Organic"E42
IDTIMWYTIM: "Organic"In the world of chemistry, an "organic" compound is often described as anything with carbon in it, and "organic chemistry" is the study of carbon compounds, but there is actually no single definition of what "organic" means in chemistry, and scientists have been arguing about it for a long time. In this edition of "I Don't Think It Means What You Think It Means," Hank does his best to illuminate the confusion so we can better understand what "organic" means to chemists. - A Cure for Ebola, Rabies, & Other Virus Villains?
E44A Cure for Ebola, Rabies, & Other Virus Villains?Viruses are among humanity's greatest threats and it seems like they're always one step ahead of us. But this week, biologists say that they've discovered a new weapon we can use against some of our most nefarious virus enemies - and it comes from our friends the plants. Get the full story from Hank in today's SciShow news. - Top 5 Deadliest Substances on EarthE45
Top 5 Deadliest Substances on EarthThere are natural poisons that lurk in bacteria, plants, and fungi pretty much everywhere, and they're there for good reasons (according to the organisms that produce them) - but what is it about their chemical make up that makes them so poisonous? How do their toxins attack the human body with such deadly efficiency? Discover the answers to these and other questions as Hank talks about some of the most deadly natural substances in the world. - Anxiety HurtsE46
Anxiety HurtsEverybody knows what anxiety feels like - it's annoying and counterproductive and apparently useless, so why does it exist? It turns out your anxiety isn't useless at all - it's a result of the sympathetic nervous system (in charge of the fight or flight response), which lets you respond immediately to threats and can also help you meet that looming deadline. But you don't want your SNS running the whole show - chronic anxiety not only feels crappy, it damages your cells, alters your brain chemistry, and can exacerbate a wide range of health problems. Hank has the whole story in this episode of SciShow. - NASA Needs You
E48NASA Needs YouHank usually likes to keep science and politics separated, but the reality is that a lot of scientific research in the United States is funded by the government. This is a problem right now because the disfunction in the world of politics has begun to seriously affect the realm of science. Because of sequestration, NASA needs our help! - SciShow Talk Show #7: Sinkholes, Robotic Mules & Fluffy the TarantulaE53
SciShow Talk Show #7: Sinkholes, Robotic Mules & Fluffy the TarantulaHank is joined by Peter Winkler with some news about sinkholes and DARPA's new robotic mule, and then the boys are joined by Jessi from Animal Wonders and her special friend "Fluffy" the Chilean rose hair tarantula. - Patenting Person Parts
E59Patenting Person PartsSince the advent of genetic engineering, a lot of weird questions have cropped up, particularly with regard to what information a company can patent. Individual genes, as they are discovered, are now immediately patented and can be controlled by the company that owns the patent. Do those gene patents encourage science by providing a monetary incentive for researchers? Or do they discourage science by creating artificial barriers to the use and study of genes by the companies that don't hold the patents. Guest host Michael Aranda discusses. - SciShow Talk Show #8: Human-Powered Helicopters and a Red FoxE60
SciShow Talk Show #8: Human-Powered Helicopters and a Red FoxDa Vinci imagined a helicopter powered solely by human muscles. Now more than 500 years later, two teams are using advanced materials to try and make that dream come true. Hank and Catilin discuss these two teams and the Sikorsky Prize that they are battling for. Then Jessi from animal wonders shows of Seraphina the red fox! - The Science of TerrorismE63
The Science of TerrorismScience can help create understanding where there is none, but is it possible to study and understand terrorists if we're too busy doing everything we can to stop it? Terrorism is notoriously difficult to study because governments constantly subpoena scientists lists of contacts, making source anonymity impossible. And an outbreak of TB in North Korea is terrible and unnecessary, but it is providing an opportunity for North Korea to, potentially, join the global scientific community. - The Times and Troubles of the Scientific MethodE64
The Times and Troubles of the Scientific MethodScience is working tirelessly night and day to disprove its own theories about how the universe works (or at least, that's what science thinks it's doing). Hank tells us a quick history of how we came to create and adopt the scientific method and then gives us a vision of the future of science (hint: it involves a lot more computers and a lot less pipetting). - The Terrifying Promise of Robot Bugs
E67The Terrifying Promise of Robot BugsImitating nature to build a better (or possibly more terrifying) future. We've been trying to build flapping-wing robots for hundreds of years. And now, ornithopters are finally being developed, and may be used mostly for military purposes. Piezoelectrics make those little bugs possible, and also enhances the ability of robot arms to feel, in other news from The International Journal of Robotics. - SciShow Talk Show #9: Brain Frames and a Harris's HawkE68
SciShow Talk Show #9: Brain Frames and a Harris's HawkToday on the SciShow Talk Show, our Technical Director Nick Jenkins stumps Hank about how many frames per second the human eye can see, and Jessi from Animal Wonders shares Hara the Harris's hawk. - Marvelous Medicinal MaggotsE70
Marvelous Medicinal MaggotsAlthough it may sound crazy, many doctors use maggots today to clean wounds of dead and infected tissue. This process, called debridement, is important for preventing the spread of infection in a world of increasing antibiotic resistance. Hank has more details on the marvelous maggot in today's episode of SciShow. - THE CICADAS ARE COMING!
E71THE CICADAS ARE COMING!Cicadas have developed an amazing strategy for growth, survival, reproduction, and overcoming predation by...doing nothing. They do nothing for years (except sip at the juice excreted from root structures) before emerging in huge, simultaneous swarms. The swarm is so huge that predators can't consume even a fraction of it, but so rare that predator populations can't sustain themselves between emergence events. Clever little things! - The Most Venomous Animals in the WorldE72
The Most Venomous Animals in the WorldThere are a lot of ways to kill and be killed in the animal kingdom, but only a lucky few use the powers of venom. Not all are closely related, so how did they acquire the same defenses, where did venom come from, and how does it work? And what animals can kill you the most quickly? Find the answers to these questions, and more, in today's episode of SciShow. - How To Make AntivenomE74
How To Make AntivenomBitten by a venomous snake? There's hope! French scientist Albert Calmette developed the first snake antivenom in the late 1890s, and did such a good job that we use his technique to this day. Antivenom works by stimulating the production of antibodies which can smother venom's toxic effects, preventing spread and rendering them harmless. But how do you make it? Well, stay tuned to this episode of SciShow to find out. - Exotic Chemistry: World's Oldest Water and The Rarest Element
E75Exotic Chemistry: World's Oldest Water and The Rarest ElementThis week's SciShow news brings you discoveries involving two of the most exotic substances on Earth - the world's rarest element and the world's oldest water. Two great tastes that taste great together? Stay tuned to find out. - SciShow Talk Show #10: Telepathic Rats and a Red-lored AmazonE76
SciShow Talk Show #10: Telepathic Rats and a Red-lored AmazonEmily Graslie of The Brain Scoop is back again to stump Hank and to tell us about some fascinating new research in the field of rat telepathy (NO JOKE). Then Jessi from Animal Wonders shares Zoe the Red-lored Amazon parrot. - Angelina Jolie & Breast CancerE77
Angelina Jolie & Breast CancerWhat would you do if you found out that cancer could be lurking in your genes? More people are getting news like that these days as more kinds of cancer are being linked to specific genes and genetic tests let doctors screen your individual genome for signs of susceptibility to the disease. Is the only choice in these cases to remove the part of you that might develop cancer? Hank has some thoughts on this question and more in today's SciShow. - Schrödinger's iPad? New Breakthroughs in Quantum Computing
E79Schrödinger's iPad? New Breakthroughs in Quantum ComputingTwo developments in quantum computing in the past couple of weeks are the harbingers of a whole new era of smart technology. Google announced that it's building a quantum computer designed by a company called D-Wave in partnership with NASA, and government scientists at Los Alamos National Laboratory revealed that they developed a secure quantum computing network two years ago! Get the details about these developments in this episode of SciShow News. - A History of Earth's ClimateE80
A History of Earth's ClimateEarth had a climate long before we showed up and started noticing it and it's influenced by a whole series of cycles that have been churning along for hundreds of millions of years. In most cases those cycles will continue long after we're gone. A look at the history of climate change on Earth can give us some much needed perspective on our current climate dilemma because the surprising truth is, what we're experiencing now is different than anything this planet has encountered before. So, let's take a stroll down Climate History Lane and see if we can find some answers to a question that's been bugging Hank a lot lately - just how much hot water are we in? - Hallucinogens as MedicineE81
Hallucinogens as MedicineIs it possible that, because of the war on drugs, we have demonized a treatment for otherwise untreatable diseases? A way to increase personal well-being, permanently treat depression, break the cycle of addiction, and ease the transition from life into death? The solution to all of these problems (for many people) might be a nice, hallucinogenic trip, but taking that trip can be harder than you might think. - Rogue WavesE82
Rogue WavesFor a long time, rogue waves (defined as waves that are greater than twice the height of surrounding waves) were thought to be a myth, like mermaids or the kraken, but recent developments in satellite imagery and oceanic instruments now show that they occur on a semi-regular basis. But we're still not sure why... - Kickstarting a Space Telescope?!
E83Kickstarting a Space Telescope?!In the past few years the rise of crowdfunding has allowed for some pretty cool stuff to start existing, and today Hank is excited to announce another awesome Kickstarter - Planetary Resources (of asteroid mining fame) in partnership with the Museum of Flight and The Planetary Society in Kickstarting a space telescope. F'real. - SciShow Talk Show #11: Cyborg Eyes and Stumpy the Dumpy Tree FrogE84
SciShow Talk Show #11: Cyborg Eyes and Stumpy the Dumpy Tree FrogSciShow graphics guy Louey Winkler discusses LED contact lenses and the implications of enhancing and assisting human beings with technology, and then attempts to stump Hank with a physics riddle. Jessi from Animal Wonders shares Stumpy the Whites tree frog. - What's The Oldest Tree in the World?E86
What's The Oldest Tree in the World?Ancient trees are fascinating, but the answer to the question in the title isn't as cut and dried as it might first seem. There are two major contenders for the superlative, and Hank has all the important information on both of them in this episode of SciShow. Which one would you give the title to? - Top 10 New Species of the Year!
E87Top 10 New Species of the Year!Scientists around the world discover about 18,000 new species every year. Each new organism has not only to be found, but also studied, compared, identified and organized -- that's taxonomy, the science of classifying living things and exploring the evolutionary relationships between them. Every May, to celebrate the latest achievements in the field, as well as the birthday of the man who invented it (Swedish scientist Carl Linnaeus), the International Institute for Species Exploration weighs in on the most impressive discoveries of the previous year - the top ten new species of 2013. Who made the list this year? Hank has all the fascinating details in this episode of SciShow. - Goodall, Fossey & Galdikas: Great MindsE89
Goodall, Fossey & Galdikas: Great MindsToday we know that humans and chimpanzees share 99% of their DNA and that we have a lot in common. Not just how we look, but how we behave, form groups, defend our turf, and love each other. People didn't always see other primates this way, but in the 1960s and '70s, some amazing intrepid women came along to turn primatology on its hairy head. Jane Goodall, Dian Fossey and Birute Galdikas studied chimpanzees, gorillas and orangutans, respectively, and are the very definition of great minds of science. Their contributions to humanity's knowledge about its closest living relatives is the subject of today's SciShow: Great Minds. - Space Hype!
E91Space Hype!Sometimes science news is less about stuff that actually happened, as much as it is about people going "PAY ATTENTION TO ME" and space news is no exception. In fact this week there was probably as much hype as real news, all in the name of bringing people's attention to the importance of space exploration, but Hank is sharing it all with you in this episode of SciShow. - SciShow Talk Show #12: Pumas and Slither the Gopher SnakeE92
SciShow Talk Show #12: Pumas and Slither the Gopher SnakeHank and Katherine talk about the wild cat known variously as a puma, mountain lion, cougar, panther and catamount and then Jessi from Animal Wonders brings a special animal guest to visit. - What is Saliva?E93
What is Saliva?Salvia divinorum, despite sounding like a spell from the world of Harry Potter, can't turn you into an inanimate object, make you leave your body, or set your feet on fire. However, it can make you FEEL like all of those things are happening. This little plant is a hallucinogen - one so powerful and unique that the DEA isn't quite sure how to regulate it. Hank's got the details on this psychotropic member of the sage genus in this episode of SciShow. - Weird Pregnancy TestsE94
Weird Pregnancy TestsHank takes us on a trip through the history of pregnancy tests through the ages, from ancient Egypt to the first home pregnancy tests of the 1970s. It's generally not a very pretty story, but it should help make us very grateful for the modern conveniences we have today. - BigBrain & Supermoon
E95BigBrain & SupermoonFrom brains to heavenly bodies, this week brings us some super-sized science... BigBrain is the highest resolution map of the human brain that's ever existed; a super high resolution interactive model of King Tut's tomb for anyone to explore from the comfort of home; and tonight, the moon itself will be super-sized - go have a look! - 7 Bizarre Uses for Animal SecretionsE96
7 Bizarre Uses for Animal SecretionsYou're probably aware of lots of the things we take from animals, but for centuries, humans have been sneaking animal secretions into a bunch of things you probably didn't know about, like your Easter candy, your Mom's perfume, and even that cigarette you probably shouldn't be smoking. We also continue to enjoy delicacies that are only made possible because they come out of some animals' mouths, glands, and butts... So, how many secretions have you slathered on or ingested lately? First you'll have to find out what they are and how they get into your body, which is what Hank will be telling you about in this episode of SciShow. Hooray! - The 3 Coolest Things Built By BugsE98
The 3 Coolest Things Built By BugsLong before there were strip malls, skyscrapers, and combination Pizza Hut/Taco Bells, nature had its own architects: all kinds of creatures create all kinds of structures for living, raising offspring, or maybe just the occasional hook-up. Some of the mightiest and most delightfully complex structures ever built have been erected by bugs, and Hank will show you three of the coolest ones in today's episode of SciShow. - SciShow Talk Show #13: Spinal Posture & A Legless LizardE100
SciShow Talk Show #13: Spinal Posture & A Legless LizardIn this episode of the SciShow talk show, Michael and Hank discuss human posture and evolution and Hank shares some personal information, and then Jessi from Animal Wonders shares Leonard, the legless lizard. - Why Do Tornadoes Hate America?E102
Why Do Tornadoes Hate America?On the 4th of July, Americans like to celebrate the things that make the United States unique, and a lot of those things have to do with our geography. That remarkable geography is also responsible for some pretty unique weather, and unfortunately for the millions of people living in the Midwest, that weather includes tornadoes. In this episode of SciShow, Hank explains why scientists think the U.S. is prone to so many tornadoes. - Starfish Eyes, Octopus Blood, and Human Evolution in Action
E103Starfish Eyes, Octopus Blood, and Human Evolution in ActionYou're probably aware that nature has come up with some pretty fascinating animal adaptations over the millennia, and in general, the stranger the adaptation, the more important it is to that organism. Today on SciShow News, Hank has some new discoveries about weird adaptations to report on (including one in humans!), along with the reasons they evolved the ways they did. - Will You be Iron Man?E104
Will You be Iron Man?We have the technology! We can rebuild...ourselves! Human interface technologies like Google Glass, robotic prosthetics, and bionic eyes have the potential to help people recover lost abilities, but also to grant us new abilities. Will you someday be able to turn on your super-human hearing just by thinking about it? Maybe...if you live long enough. The question of whether we /should/ well, we'll leave that to the philosophers. This is SciShow! - How to Make A HumanzeeE106
How to Make A HumanzeeWe all know about inter species animal hybrids - Napoleon Dynamite's favorite animal, the liger, is a typical example. But could a human and our closest primate relative the chimpanzee also breed a living hybrid? Hank explores this ... delicate question in this episode of SciShow. - Roswell & New Signals from Space
E107Roswell & New Signals from SpaceWith news of radio signals from distant galaxies, a government agency that wants to investigate extra-terrestrial life, and the 66th anniversary of the Roswell Incident, this week has felt like a '90s science fiction melodrama. Hank's got all the pertinent details in this episode of SciShow News. - What's Happening to Honey Bees?E109
What's Happening to Honey Bees?You've probably heard about the sudden and mysterious drop in honey bee populations throughout the U.S.A. and Europe. Beekeepers used to report average losses in their worker bees of about 5-10% a year, but starting around 2006, that rate jumped to about 30%. Today, many large beekeeping operations are reporting that up to 40 or 50 percent of their swarms have mysteriously disappeared. This massive die-off of honey bee populations has been dubbed colony collapse disorder, and it is a big, big deal. Find out more in today's episode of SciShow. - Why Do People Kill? And Other Revelations Of Human Nature
E111Why Do People Kill? And Other Revelations Of Human NatureThere are a lot of things that are still not fully understood about the species Homo sapiens - what makes us US? What makes us move the way we do, think the way we do, and kill the way we do? Today on SciShow News, Hank gives us a little bit of insight into human nature. - 4 Real Inventions Inspired by Science FictionE112
4 Real Inventions Inspired by Science FictionWhere science fiction becomes science fact - that is the place Hank is exploring in today's episode of SciShow. Many inventions we use today were first imagined in stories that described fantastical futures. Hank talks about the origins of four of these: the cell phone, the submarine, the telemanipulator (or robot arm), and the taser. Blast off for knowledge! - The World's First Human-Made Nuclear ReactorE114
The World's First Human-Made Nuclear ReactorToday on SciShow, Hank brings us a little science history, telling us the tale of the world's first human-made nuclear reactor, which was built by a team of scientists and students led by Enrico Fermi in a converted squash court under a football field in Chicago. Yes, that Chicago. - SciShow Talk Show #15: All About Poop, Plus a TortoiseE116
SciShow Talk Show #15: All About Poop, Plus a TortoiseThe SciShow Talk Show has a new look! And a new guest who isn't new at all - Jessi Knudsen Castañeda from Animal Wonders joins Hank to talk about one of her favorite subjects: poop! They are joined by Augusto Castañeda and Yucca the red-footed tortoise for a visit. - Pliny The Elder: Great MindsE118
Pliny The Elder: Great MindsBefore there was Google, there were encyclopedias. The very idea of these vast collections of knowledge can be credited to Pliny The Elder. So who was he, and why does he seem to pop up everywhere from Alchemy to Zoology? Hank has the story in this edition of SciShow: Great Minds. - The Science of SweetnessE120
The Science of SweetnessSugar, honey, listen up. Humans love the sweet taste of sweetness, but have you ever wondered why? What's the evolutionary purpose behind our love for sweets? Why can we taste sweet anyway? What are those sugar substitutes really made of? And will this diet cola give me cancer? Hank and SciShow have the answers! - The Scary American Bat Die-OffE121
The Scary American Bat Die-OffIn North America, bats are in mortal danger, and the poor little guys can't even activate their own Bat-Signal to call for help. A terrible infection is ravaging their populations, and it's as serious as a heart attack. Hank has the details about what's killing our favorite flying mammals, and what you can do to help. - 3 Awesome Discoveries Made by Curiosity
E1223 Awesome Discoveries Made by CuriosityHappy birthday, Curiosity! Michael Aranda and SciShow News celebrate the first anniversary of the Mars Science Laboratory landing on Mars with 3 awesome discoveries that the universe's coolest rover has made so far. Hints: they involve air, radiation and, yes, water! - What's Killing the World's Amphibians?E124
What's Killing the World's Amphibians?Of the more than 7,000 known species of amphibians in the world, an estimated one third are now threatened with extinction. Hank breaks down the science behind the decline of amphibians around the world, and what you can do to help. - Acid, Poop, and Barf: Vultures' Secret WeaponsE125
Acid, Poop, and Barf: Vultures' Secret WeaponsVultures, you eat old, putrid dead things for a living. How is that not killing you? Hank explains the secret weapons vultures use to fight off disease, avoid predators, and beat the heat. Prepare for a Sci-Show Gross-Out! - The Science of HyperloopE126
The Science of HyperloopMichael Aranda explains the nuts and bolts of Hyperloop, the new magnet-driven, solar-powered transit system proposed by Spacex genius Elon Musk. Learn how Musk answered three vexing questions to create the transportation of the future -- or maybe the transportation of Futurama. - The How, Why, and How Much of OilE127
The How, Why, and How Much of OilEveryone does it -- using oil, that is. But how much do we have left? How do scientists find it? And where are they looking for it now that the easiest pickings have been taken? Hank has the answers to the how, why and how much of oil. Like SciShow? Want to help support us, and also get things to put on your walls, cover your torso and hold your liquids? - 3 Facts About LemmingsE128
3 Facts About LemmingsLemmings are small, thickset vole-like animals that live in the Arctic tundra. They live in a harsh environment, are super-cute, kinda mean, and totally misunderstood. But here at SciShow we're going to set the record straight with 3 Actual Facts About Lemmings. - The Curious History of the Lab RatE129
The Curious History of the Lab RatIf you give them any thought at all, you probably associate them with sewers, cargo ships and maybe animated movies about animals that want to become French chefs. But for almost 200 years, tens of millions of rats have played a central role in science, performing a job they did not volunteer for, and one that almost always results in a premature death. Here at SciShow we explore the big questions like, "Why the rat?". - Healing Hearts, Space Jewelry, and the Newest MammalE130

Human Experimentation: The Good, The Bad, & The Ugly In the early days of the space race, agency researchers in Russia and at NASA really weren't sure all what would happen to an astronaut in space. They didn't know if a human mind could handle actually seeing Earth or what would happen to the human body when exposed to long periods of weightlessness. Would their blood forget which way to pump? Would their eyeballs shift or their inner ears wig out? They sent up mice and monkeys and dogs, to see what happened, and in 1961, the Russians strapped a man to a rocket headed for orbit. Yuri Gagarin was the first person in space. The ultimate human guinea pig, he survived, becoming an international hero. - What Happens If You're Struck By Lightning?E144
