  • When You Have Cancer, But You're Fine: Cancer Overdiagnosis
    November 14, 2019

    Studies suggest that if you made full-body scans part of your regular routine, you’d find a bunch of cancers over the years, but it wouldn't change your odds of having a life-threatening cancer. This is mostly because our definition of cancer is a little too broad. Hosted by: Hank Green SciShow has a spinoff podcast! It's called SciShow Tangents.

  • Protecting Penguins in South Africa
    November 14, 2019

    Penguin Beach might be over, but our work to protect these dapper birds never ends. 🐧 Watch the full series: http://sdzoo.com/PBYouTube Jack, Rocko, Hoover, McKinney, Lori, and the rest of the gang aren’t just here for our amusement. African penguins are endangered, and our feathered friends live in a breeding colony that is part of the Species Survival Plan (SSP) to safeguard the species from extinction. African penguin numbers have declined 60% in the last 30 years, so every bird is precious. We also partner with SANCCOB (South African Federation for the Conservation of Coastal Birds), which rescues, rehabilitates, and releases African penguins and other sea birds along the coast of South Africa. Efforts to bolster the number of wild birds, along with the efforts of Association of Zoos and Aquariums (AZA)-accredited Zoos and Aquariums to maintain a sustainable population, will ensure that our lovable flipper friends waddle into our hearts for generations Facebook - https://www.facebook.com/SanDiegoZoo/ Instagram - https://www.instagram.com/sandiegozoo/ Twitter - https://twitter.com/sandiegozoo Giphy - https://giphy.com/sandiegozoo TikTok - @sandiegozoo

  • The myth of Loki and the master builder - Alex Gendler
    November 14, 2019

    Dive into the Norse myth of how Loki tricked a stranger into building the great wall of Asgard to keep the realm safe from giants. -- Asgard, a realm of wonders, was where the Norse Gods made their home. There Odin’s great hall of Valhalla towered above the mountains and Bifrost, the rainbow bridge, anchored itself. Though their domain was magnificent, it stood undefended from the giants and trolls who sought to destroy them. But a stranger appeared and made the gods an offer. Alex Gendler details the myth of the master builder. Lesson by Alex Gendler, directed by Hype CG.

  • Reform and Revolution 1815-1848: Crash Course European History #25
    November 12, 2019

    In the aftermath of the revolutions and upheaval in 18th and early 19th century Europe, there was a hunger for reform across the continent. Reformers like Robert Owen, Charles Fourier, and Auguste Comte proposed radical new ideas, and at the same time, regular people began to stand up and ask for greater equality, and a louder voice in how they were governed. Results were mixed, but a lot of the ideas that emerged during this time are still echoing in our world today. Sources -Hosking, Geoffrey. Russia: People and Empire.

  • The dangers of mixing drugs - Céline Valéry
    November 12, 2019

    Explore the science of why mixing drugs and drug interactions with other substances can lead to dangerous health complications. -- Which of the following is risky behavior: a person taking cholesterol medicine with grapefruit juice? Or a person taking Acetaminophen before going out for drinks? Or a person on blood thinners who takes an aspirin? Turns out, all of them are risky.

  • Why do humans have a third eyelid? - Dorsa Amir
    November 11, 2019

    Discover how evolution and natural selection influence why the human body has vestigial organs— body parts that no longer serve their original purpose. -- You know that little pink thing nestled in the corner of your eye? It’s actually the remnant of a third eyelid. In humans, it’s vestigial, meaning it no longer serves its original purpose. There are several other vestigial structures in the human body, quietly riding along from one of our ancestor species to the next. But why have they stuck around for so long? Dorsa Amir investigates.

  • Why haven’t we cured arthritis? - Kaitlyn Sadtler and Heather J. Faust
    November 7, 2019

    Get to know the science behind what causes the stiff, creaky joints of the most common forms of arthritis and what you can do to prevent it. -- The bad backs, elbow pain, and creaky knees so common in older people often aren't just “old age.” In fact, the source of this stiffness plagues many young people as well. The culprit is arthritis: a condition that affects over 90 million people in the U.S. alone. What makes arthritis so pervasive, and why haven’t we found a cure for it? Kaitlyn Sadtler and Heather J. Faust investigate. Lesson by Kaitlyn Sadtler and Heather J. Faust, directed by CUB Animation.

  • Game theory challenge: Can you predict human behavior? - Lucas Husted
    November 5, 2019

    Solve this classic game theory challenge: given integers from 0 to 100, what would the whole number closest to ⅔ of the average of all numbers guessed be? -- Given a range of integers from 0 to 100, what would the whole number closest to 2/3 of the average of all numbers guessed be? For example, if the average of all guesses is 60, the correct guess will be 40. The game is played under conditions known to game theorists as “common knowledge:” every player has the same information— they also know that everyone else does too. Lucas Husted explains.

    Dive into the Taino myth of the sea, and watch as Deminan and his brothers accidentally create a new world from a giant gourd. -- Before the world of humans began, there was the world of the gods. Four brothers wandered this celestial realm. One day, the brothers snuck into a spirit’s house and spotted a giant gourd hanging in the corner. But as they tried to look inside the gourd, they dropped it. It broke apart, releasing a deluge that formed a new world. Bill Keegan details the Taino myth of Deminan and the sea.

  • Making a String form a perfect circle (Surface Tension)
    November 3, 2019

    Whats the Science behind this: Surface tension pulls in a way that minimizes the area with the soap membrane. This means it maximizes area insight the string without the membrane. Biggest area per given circumferences the string results in perfect circle. The soap water on the outside of the string pulls towards the bubble frame and opens up the string loop. And because the soap pulls with the same strength everywhere, its forms a perfect circle. I used Dawn soap to make my bubble solution. Make sure to dip string into the bubble solution before lightly dropping onto the bubble frame.

  • AI Playing Games: Crash Course AI #12
    November 1, 2019

    As we mentioned last episode, one of the best test spaces for building new AI systems are games. This is because games provide a great framework for an AI to learn an objective and slowly improve. In recent years, AI has made huge strides in games from beating Jeopardy! champions to crushing a five-person team in DOTA 2. Today, we’re going to walk you through creating a Tic Tac Toe bot that uses the minimax algorithm to become undefeatable and we’ll talk about evolutionary neural networks like in SethBling’s MarI/O project. Next week we’ll create our very own game and create an AI to master it! Watch SethBling’s MarI/O video: https://www.youtube.com/watch?v=qv6UVOQ0F44 Crash Course is produced in association with PBS Digital Studios: https://www.youtube.com/pbsdigitalstudios Crash Course is on Patreon!

  • Penguin Beach | Episode 4 – Awkward Teens
    October 31, 2019

    There’s no feather fairy for Jack and Lori’s lost baby feathers. Our molting “teens” are going through a pretty rough phase this week as they transition from their juvenile plumage into their water-proof adult tuxedo. Adult African penguins go through this “catastrophic molt” every year, typically between September and January. During the molting process, adults remain on land and don’t eat while their old feathers are replaced with shiny new ones. Don’t worry, they fill up on fish and increase their food intake before the molting process so they can live off these fat reserves while they fast. Penguins lose all their feathers at once and often resemble a disheveled pillow. 🐧 Website: http://sdzoo.com/PenguinBeach Facebook - https://www.facebook.com/SanDiegoZoo/ Instagram - https://www.instagram.com/sandiegozoo/ Twitter - https://twitter.com/sandiegozoo Giphy - https://giphy.com/sandiegozoo

  • Are Vampires Real? Of Course Not, But . . .
    October 31, 2019

    Check out Monstrum: https://www.youtube.com/channel/UCO6nDCimkF79NZRRb8YiDcA Halloween season wouldn’t be what it is without the undead. This week on Reactions, we unpack the chemistry that may have inspired one of our favorites: the vampire. When you think “vampire” some of today’s most popular vampires might come to mind. Attractive bloodsuckers with pale, sometimes sparkling skin. But in the 18th and 19th centuries, when European vampire lore first really took off, they were a bit more...morose and, instead of that crystal-clear skin, they appeared kind of sickly with a reddish complexion. Vampires were often depicted as men from poor, rural areas, who, after dying--often from diseases like the plague--would emerge from their coffins to wreak havoc on a nearby town, sucking the blood of humans, turning them into vampires as well. So how did this folklore come about? Possibly...disease.

  • The Congress of Vienna: Crash Course European History #23
    October 30, 2019

    The end of the Napoleonic Wars left the great powers of Europe shaken. Judging from the destruction that had been wrought across the continent, it seemed to the powers that be that the Enlightenment had liberated the people, and led to disaster. So, everybody got together in Vienna to have a Congress, and to try to put Europe "right" again. By "right" I mean they wanted to go back to the old days of kings, queens, and nobles running the show. But this new yearning for the past pervaded the continent. Roomanticism arose at the same time, looking back at (imagined) golden age of Medieval Times. Today we'll talk about the Congress of Vienna, The Holy Alliance, and the Romantic movement across the arts. Sources -Blanning, Tim. The Romantic Revolution: A History.

  • Claws vs. nails - Matthew Borths
    October 29, 2019

    Discover the evolutionary purpose of nails, and explore the theories of why they evolved from claws over 55 million years ago. -- Consider the claw. Frequently found on animals around the world, it’s one of nature’s most versatile tools. Bears use claws for digging as well as defense. An eagle’s needle-like talons can pierce the skulls of their prey. Even the ancestors of primates used to wield these impressive appendages, until their claws evolved into nails. So what caused this adaptation? Matthew Borths investigates. Lesson by Matthew Borths, directed by Augenblick Studios.

  • How close are we to uploading our minds? - Michael S.A. Graziano
    October 28, 2019

    Investigate the possibility of scanning the human brain and uploading our minds and consciousness to a digital world. -- Imagine a future where nobody dies— instead, our minds are uploaded to a digital world. There they could live on in a realistic, simulated environment with avatar bodies, calling in and contributing to the biological world.

  • He Grew Up in Antarctica — And Now He's Leaving | National Geographic
    October 28, 2019

    Dion Poncet came of age in a place almost no one calls home. He was born on a sailboat in Leith Harbour, an abandoned whaling station on South Georgia island. His father, a French adventurer, had met his mother, an Australian zoologist, on a jetty in Tasmania while sailing his boat around the world. The couple started a family in the South Atlantic. For years they traversed the west coast of the Antarctic Peninsula, surveying wildlife in uncharted bays—seals, flowering plants, seabirds—with three boys in tow. Dion was the first. ➡ Subscribe: http://bit.ly/NatGeoSubscribe #NationalGeographic #Antarctica #ClimateChange About National Geographic: National Geographic is the world's premium destination for science, exploration, and adventure.

  • Robotics: Crash Course AI #11
    October 25, 2019

    Robots aren’t like humans who can do a lot of different things. They’re designed for very specific tasks like vacuuming our homes, assembling cars in a factory, or exploring the surface of other planets. So even though it may be a while before we have a general household robot that can do it all, robots are still really important because they can do some things incredibly well even better than humans. So today, we're going to take a look at the role of AI in overcoming three key challenges in the field of robotics: localization, planning, and manipulation.

  • Penguin Beach | Episode 3 – New Day, New Drama
    October 24, 2019

    Lori’s back at it and baiting the boys with her signature neck preen. 😏 With breeding season just around the corner, relationships on Penguin Beach are heating up. Some couples are getting their practice in early whereas others are taking the time to seriously reconsider their current partner bonds. No relationship is safe when this many pheromones are flying free, so brace yourself for this week’s hidden secrets and new relationships. Fun facts about African penguin family life: African penguins reach sexual maturity around four years of age. At this time, the male will court the female with a donkey-like bray. Who can resist? (This call also earned them the nickname jackass penguin.) Once the male is accepted by the female, the pair will continue to bond for the rest of the season—and they sometimes remain bonded for future mating seasons, but not always. The female digs a burrow under a bush or a rock where she lays two eggs. Both parents take turns incubating the eggs for up to 40 days. Once the chicks hatch, the parents share the responsibility of keeping the chicks warm and fed constantly for the first 30 days. Once they reach a month old, the chicks are left for short periods with other chicks while their parents hunt for food. The chicks huddle together in large "nursery groups" to keep warm and help protect each other from predators. The juveniles leave the colony when they are around four months of age and have developed their juvenile plumage.
