- Quantum Fishing for the Higgs BosonE2
Quantum Fishing for the Higgs BosonHank talks to some VIPs from CERN about the question on everyone's mind: does the Higgs Boson particle exist? And describes how CERN is going about finding the answer. Hank interviewed Sergio Bertolucci on October 11, 2011 and Rolf Heuer on October 25, 2011. In the time since then, CERN researchers have gotten some tantalizing clues, but the Higgs boson has yet to be found. - Curiosity: Mars' Next Visitor
E13Curiosity: Mars' Next VisitorPlutonium powered robot car! With a laser gun!

IDTIMWYTIM: Schrodinger's Cat"I Don't Think It Means What You Think It Means" examines scientific theories that have taken on a life of their own in popular culture & we help you understand what they really mean in scientific terms. Today we take on Schrodinger's Cat, the famous thought experiment by Austrian physicist Erwin Schrodinger. - The Evolution of Male Homosexuality
E69The Evolution of Male HomosexualityHank goes from space to sex and then to motherhood, covering the SpaceX launch, a mission to the moons of Jupiter, intersexual workplace rivalries, the evolution of male homosexuality, the fossil evidence of squishy baby skulls, toddler body bias, and the price of breastfeeding. - Strong Interaction: The Four Fundamental Forces of Physics #1a
E74Strong Interaction: The Four Fundamental Forces of Physics #1aPart one of a four part series on the fundamental forces (or interactions) of physics begins with the strong force or strong interaction - which on the small scale holds quarks together to form protons, neutrons and other hadron particles. - Strong Interaction: The Four Fundamental Forces of Physics #1b
E76Strong Interaction: The Four Fundamental Forces of Physics #1bHank continues his primer on the strongest of the four fundamental interactions of physics, the strong interaction. Today he talks about the nuclear force and a force carrier called a pion. - Asteroids to Watch Out For
E78Asteroids to Watch Out ForHank tells us about NASA's Near-Earth Object Program, which tracks the paths of asteroids and categorizes them according to the likelihood that they will strike the Earth at some point in the future.Hank tells us about NASA's Near-Earth Object Program, which tracks the paths of asteroids and categorizes them according to the likelihood that they will strike the Earth at some point in the future. - More on Mating & Monogamy
E84More on Mating & MonogamyHank clarifies the misconceptions about Chagus disease, discusses a couple of interesting celestial events - one that happened in the past and one that will happen in the distant future, and sheds more light on the benefits of sexual reproduction. - Gravitation: The Four Fundamental Forces of Physics #3E85
Gravitation: The Four Fundamental Forces of Physics #3Hank continues our series on the four fundamental forces of physics with a description of gravitation - the interaction by which physical bodies attract with a force proportional to that of their masses, and which is responsible for keeping planets in orbit, among other things. - IDTIMWYTIM: Heisenberg Uncertainty PrincipleE87
IDTIMWYTIM: Heisenberg Uncertainty PrincipleThe Heisenberg Uncertainty Principle might not mean what you think it means: Hank clears things up for us in this edition of IDTIMWYTIM, by distinguishing between the Uncertainty Principle and the Observer Effect, which are often conflated. - Gregor Mendel: Great Minds
E88Gregor Mendel: Great MindsHank brings us the story of Gregor Mendel, the Austrian monk who, with the help of a garden full of pea plants, discovered the fundamental properties of inheritance and paved the way for modern genetics. He also gives us the dirt on a scientific scandal that has followed Mendel beyond the grave. - Electromagnetism - Electrostatic Force: The Four Fundamental Forces of Physics #4a
E93Electromagnetism - Electrostatic Force: The Four Fundamental Forces of Physics #4aHank reaches the fourth and final of the four fundamental interactions in physics: electromagnetism. In this part, he teaches us about the electrostatic force, which builds up a charge in an object and can travel in the form of an electron stream. Stay tuned for Part II, where we will finish up the series with the magnetic force. - Electromagnetism - Magnetic Force: The Four Fundamental Forces of Physics #4b
E94Electromagnetism - Magnetic Force: The Four Fundamental Forces of Physics #4bIn this final segment on the four fundamental forces of physics, Hank tackles the magnetic force, the second of the two ways in which electromagnetism is apparent in the universe. - This Is What Climate Change Feels Like
E101This Is What Climate Change Feels LikeHank brings you the SciShow news of the week. Recent record high temperatures and other extreme weather events around the world are climate change in action; a new fossil of an ancient human ancestor; some disturbing discoveries about so-called "bog bodies;" and a correction of an error we made about the Kelvin scale in our episode about absolute zero. - The Curiosity Rover Landing
E112The Curiosity Rover LandingThe Mars Science Laboratory or Curiosity Rover is the largest payload ever delivered to the surface of a planet and it has a terrifyingly complicated descent and landing strategy. First, the atmosphere takes it from 13,000 mph to 2,000 mph. Then a parachute takes it down to 200 mph. The final, powered-descent stage lowers the craft to 21 feet above the surface, at which point it will be lowered by a tether and the rockets will detach and crash land elsewhere. If the Curiosity survives it's descent to Mars, it will be the most robust scientific tool to ever explore another planet. The size of a small car, the craft has a planned mission length of two years, during which time it could travel over 12 miles. Curiosity's goals are to study the geology and climate of Mars, to determine whether there was once life there, and to prepare for future human exploration of the Red Planet. - Cheating Can Be Hazardous to Your Health
E118Cheating Can Be Hazardous to Your HealthHank brings you news from around the universe, including what you can't blame on global warming, why being unfaithful is hazardous to your health, and how to watch a particularly awesome spectacle coming to a sky near you. - Fritz Haber: Great MindsE119
Fritz Haber: Great MindsHank introduces us to the brilliant and heartless Fritz Haber, a great mind who is considered "the father chemical warfare," but who also made discoveries and innovations that helped lead to the Green Revolution which is credited with preventing the starvation of over a billion people. - Neil Armstrong Tribute
E127Neil Armstrong TributeNeil Armstrong, the first man to walk on a world that was not Earth, has died. Getting his pilot's license before his driver's license probably didn't hurt when it came to becoming one of the world's most famous men - certainly the world's most famous space man. A remarkable man who was able to accomplish many great things, his legacy is far larger than himself - he became a symbol of our greatest accomplishments and it is very sad to now be in a world without him. - When Athletes Dope ... & Einstein FTW
E135When Athletes Dope ... & Einstein FTWThis week's SciShow news has Hank bringing us a primer on the science behind various illegal and illicit ways in which athletes "improve" their bodies, proof of general relativity that we can actually see, and a new way to measure how prejudiced you are (just in time for the U.S. presidential election). Let's get this smarty started! - Good News, & Drinking Pigs
E138Good News, & Drinking PigsThe SciShow Science News Bureau brings us some GOOD news this week - Hank tells us about a newly developed vaccine for dengue fever, a newly discovered monkey species in the Democratic Republic of the Congo, and some happy pigs drinking booze for science. - Animal Magnetism: How Animals NavigateE142
Animal Magnetism: How Animals NavigateHank tells us about new research into the question of how animals navigate from place to place - while the problem is still unresolved, we do have some hypotheses, and they all involve something called "magnetoreception." - The Science of DreamingE143
The Science of DreamingDreaming is one of the weirdest things we do & in this SciShow infusion Hank talks about how science is helping us understand why we dream, what our brains are up to when they're doing it, and why dreaming may be critically important to the function of our waking brain. He also touches on the fascinating subject of lucid dreaming. Try to stay awake! - The Science of the Cinnamon ChallengeE144
The Science of the Cinnamon ChallengeHank explains the science behind the "cinnamon challenge," and reveals why it is nearly impossible to complete. Do not attempt the cinnamon challenge! Instead, why not just watch some videos of the thousands of YouTubers failing at it! That's what we at SciShow call doing it "the Smart Way." - The World's 5 Rarest AnimalsE149
The World's 5 Rarest AnimalsToday's extraordinarily depressing dose comes to you in honor of Lonesome George, the world's last Pinta Island tortoise, who passed away earlier this summer - Hank brings us the stories of five more extremely rare animals who may be headed the same way as George. - Supersonic Free Fall and the New Element: Hankium?
E150Supersonic Free Fall and the New Element: Hankium?Hank brings you the news of a newly discovered dinosaur he is kind of afraid to look at, a way to sequence your genome in less time than it takes to get your clothes dry cleaned, & two new adventures that will take place in space - one going up, and the other coming down! Stow your tray tables, SciShow News is taking off! - Nikola Tesla: Great MindsE151
Nikola Tesla: Great MindsHank brings us the tale of the bizarre and eccentric genius with the crazy eyes who spent his life increasing awesome wherever he went, and contributed in some way to pretty much every cool invention you can think of. Nikola Tesla spoke eight languages and, at the time of his death, held over 700 patents and was being investigated by the US government for claiming to have invented a 60 million volt death ray. Tesla was an undisputed genius, and SciShow gold. - IDTIMWYTIM: Stochasticity - THAT'S RandomE156
IDTIMWYTIM: Stochasticity - THAT'S RandomHank helps us understand the difference between the colloquial meaning of randomness, and the scientific meaning, which is also known as stochasticity. We will learn how, in fact, randomness is surprisingly predictable. - Venomous Mammals, Sensory Receptors & the Moon's True Origin Story
E159Venomous Mammals, Sensory Receptors & the Moon's True Origin StoryHank describes to us some news stories that illustrate how science is continually changing the things we think we "know" - from the status of various animals species, to the way our senses work and even where the Moon came from - scientists ask questions and make discoveries that change the world, and our understanding of it, every day. - Prions: The Real Zombie-MakersE161
Prions: The Real Zombie-MakersHank is tired of zombies in popular culture, and while acknowledging that dead people are scary (especially if they start moving around), he brings us some information on prions - misfolded proteins that are responsible for destroying brains and get passed around mostly by getting eaten. So yeah, zombie stuff. - Astrobiology & the Search for Alien Life
E164Astrobiology & the Search for Alien LifeHank talks about astrobiology - the study of and search for life in the universe off Earth. Right now, the field has more questions than answers, but all they all seek to answer that one fundamental query: are we alone in the universe? - Secrets of the Vampire Squid
E167Secrets of the Vampire SquidThis week in SciShow News, Hank tells us about some weird science, including a squid that's not a squid, animals that can talk, and new insights into how you can mess up your body much faster and for much longer than you ever thought possible! **To clarify, the subjects in Todd Anderson's research on fat intake ate two breakfast sandwiches for a total of 900 calories and 50 grams of fat, not one. Sorry for any confusion!** - Facts about Human EvolutionE168
Facts about Human EvolutionHank brings you the facts, as they are understood by scientists today, about the evolution of humans from our humble primate ancestors. On the way to becoming Homo sapiens, game-changing evolutionary breakthroughs led to the development of many hominin species, now all extinct. Hank will introduce us to these species & the breakthroughs responsible for their development, and help us understand the awesome ways in which they led to us. - How to Make a Lemon BatteryE169
How to Make a Lemon BatteryHank shows us another SciShow: Experiment! This time he's tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in the lemon. Just that delicious juice. - The Real Mayan Apocalypse
E170The Real Mayan ApocalypseThere are just six weeks left until the celestial odometer that is the Mayan calendar clicks over to the next b'akt'un, but in the meantime, scientists have been trying to solve the mystery behind the collapse of the Mayan civilization. Today, a team of anthropologists and climate scientists report a very strong correlation between the civilization's rise and fall and drought conditions. This has significant relevance for our own civilization's future - the most accurate climate models today predict that global temperatures will be much higher than previously expected, meaning more extreme heat waves & severe droughts, among other consequences. - 4 Awesome Future Space MissionsE172
4 Awesome Future Space MissionsHank fills us in on the four exploratory missions to space that he is most excited about - New Horizons is going to Pluto and the Kuiper belt; Juno is on it's way to Jupiter; Dawn is exploring two large asteroids; Rosetta will land on a comet! - Rogue Planet Discovered!
E173Rogue Planet Discovered!Today Hank brings us the news of a unique astronomical discovery - a rogue planet. He also allays our fears of an apocalyptic collision with Earth. So, this new planet is awesome, but it needs a different name - CFBDSIR J214947.2-040308.9 isn't really cutting it. Suggestions? - 3 Amazing Photosynthetic AnimalsE174
3 Amazing Photosynthetic AnimalsHank's love affair with plants takes a slight hit now that he's learned about several animal species that can photosynthesize. Fortunately, he's excited enough about these animals to share them with all of us! Let SciShow introduce you to three these special photosynthetic animals. - Fidelity Hormones, Contagious Behavior, and the Meat-Allergy Plague
E175Fidelity Hormones, Contagious Behavior, and the Meat-Allergy PlagueThis week's SciShow News finds Hank up to his elbows in weird disorders and strange behaviors, including a chemical that makes men stay faithful, new insights into what makes some behavior contagious, and the truth about a disease that makes people allergic to meat. Who's hungry? - The Physics of "Punkin Chunkin"E177
The Physics of "Punkin Chunkin""Punkin Chunkin" is the United State's annual contest to see whose homemade machine can hurl a pumpkin the farthest (without explosives!). Every November, thousands of amateur engineers converge on a farm in Delaware to put their contraptions to the test. The machines at the Punkin Chunkin festival rely on physics to get the pumpkin airborne & Hank is here to give you all the fascinating details of how it works. Happy Thanksgiving! Thanks to Science Channel for helping with this episode and giving us some money and footage to produce it. - Dark EnergyE179
Dark EnergyThe universe is huge and getting bigger all the time, and we have we have dark energy - the most mysterious force in the universe - to blame/thank for it. Thought to make up more than 70% of the energy in the whole universe, Hank describes how dark energy was theorized to exist, and how scientists are trying to explain it. - 3 Chemistry Experiments That Changed the WorldE180
3 Chemistry Experiments That Changed the WorldChemistry is the study of matter - stuff, and how it interacts with other stuff. Even though chemistry doesn't make a lot of news these days, chemists are making discoveries that change lives all the time. If Hank had to narrow down all of chemistry's flashes of brilliance into the most awesome experiments in history, he would narrow it down to these three. - From Kepler to Webb: The History of the TelescopeE182
From Kepler to Webb: The History of the TelescopeHank regales us with the history of the telescope, and then introduces us to some folks from the team who are working on the newest telescope in the chronology - the James Webb Space Telescope, an infrared telescope due to launch in 2018. Thanks to the team at Northrop Grumman for allowing us the privilege of touring their facility, and to the scientists at NASA Goddard Space Flight Center for their help with this video. - Mysterious Mars News
E183Mysterious Mars NewsHank brings us news from planets all around the solar system: Mars, Mercury, and even planet Earth have been in the news lately. A retraction from NASA about the Curiosity mission; the discovery of water and organic material in craters on Mercury; bad news for Earth's climate and good news about mRNA flu vaccines for the future. - The Most Sophisticated Mirror in the Universe
E185The Most Sophisticated Mirror in the UniverseHank summarizes the five reasons why infrared telescopes were supposed to be impossible to build, and then describes how a team of scientists and engineers overcame those obstacles to build the James Webb Space Telescope. Many thanks to Scott Willoughby and the entire team at Northrop Grumman for the tour. - News Bummers: Poison Fog, Sad Sperm & SAM
E186News Bummers: Poison Fog, Sad Sperm & SAMHank loves science because it helps us appreciate the world more, but not everything that science does makes him happy - reports of poison fog on the West coast of the United States; dramatic decreases in sperm counts; and a lack of organic molecules found in the soil on Mars (despite misleading hints reported last week) have Hank feeling a little bit Grumpy Cat. - 3 Physics Experiments that Changed the WorldE187
3 Physics Experiments that Changed the WorldPhysics investigates why the universe behaves the way that it does, and today, Hank tells us about the three physics experiments that he thinks were the most awesome at helping us understand how the universe works. - Biofilm: A New (Gross) Thing to Worry AboutE188
Biofilm: A New (Gross) Thing to Worry AboutSlime can be great, but when it's the wrong kind of slime (you know, the kind that can kill you?), it gets added to the list of things Hank wishes he didn't have to worry about. Scientists call it biofilm, and it's a type of bacterial colony the produces a sticky organic glue which anchors the organisms to each other and to whatever surface they fancy. - Eat Off Your Toilet SeatE192
Eat Off Your Toilet SeatHank talks about how your toilet is actually one of the cleanest places in your house, despite its function. Research has shown that cutting boards, dish towels and sponges have FAR more fecal bacteria on them than your toilet seat, highlighting the very sophisticated scientific ways we have of detecting bacteria as well as the sophisticated natural ways our bodies have of taking care of low levels of that harmful bacteria. So that's good news... - Science and Gun Violence
E193Science and Gun ViolenceHank looks for some things science can add to the conversation about guns and gun violence in the wake of the tragedy last week in Newtown, Connecticut. Our deepest sympathies are with the community of Sandy Hook, and with anyone whose life has been impacted by gun violence. Apologies to Newtown for mispronouncing the name of your town. - Great Minds: Henrietta Leavitt & the Human ComputersE195
Great Minds: Henrietta Leavitt & the Human ComputersHenrietta Swan Leavitt was one of a number of volunteer women astronomers who were allowed to serve as "computers" at Harvard College Observatory, doing tedious work male scientists wouldn't do, and ultimately making a discovery now known as Leavitt's Law, which allows us to measure the distance to stars.
