The myth of Loki’s monstrous children – Iseult Gillespie

Download a free audiobook version of “Where the Crawdads Sing“ and support TED-Ed’s nonprofit mission: https://www.audible.com/ted-ed

Odin, the king of Asgard, was plagued by nightmares. Three fearsome figures haunted his dreams: a massive, writhing shadow; a shambling, rotting corpse; and worst of all, a monstrous beast with a deadly bite. Though their true forms were unknown to him, he could tell they were related to Asgard’s most persistent problem: Loki. Iseult Gillespie details the myth of Loki’s secret children.

Lesson by Iseult Gillespie, directed by Layron DeJarnette, Gumboyo.

Charlotte Degot: A more accurate way to calculate emissions | TED

Greenhouse gases are colorless, scentless and invisible, making them exceptionally hard to measure. Fortunately, some tools and techniques can help — one of the most powerful being artificial intelligence, says green technologist Charlotte Degot. By processing massive amounts of data on carbon emissions, she explains how AI makes it possible for corporations to set meaningful climate targets, more accurately track their progress and, most importantly, reduce pollution over time.

Linoleum flooring is cool, actually

Everything HGTV told you about linoleum is wrong.

Subscribe to our channel and turn on notifications (🔔) so you don’t miss any videos: http://goo.gl/0bsAjO

If there were a floor covering Olympics, marble would probably get gold. Hardwood would get silver. Bronze would maybe go to tile — and linoleum wouldn’t even make the trials. Arguably the most maligned flooring there is, these days linoleum is considered (at best) something you rip out to get to the real floor. But it wasn’t always that way.

Linoleum burst on the scene in the late 19th century, the brainchild of an eccentric inventor named Frederick Walton. Before long it was an international sensation and considered the height of luxury. It was even featured on the Titanic and in British Parliament. For nearly a century, linoleum remained the flooring of choice in homes, shops, and schools all over the world.

But when linoleum fell, it fell hard. For decades it was relegated to schools, hospitals, and your grandma’s kitchen — until recently. These days, linoleum is enjoying an unexpected revival in some of the world’s coolest spaces. Watch the video above to find out why.

And “Linoleum and Lincrusta: The Democratic Coverings for Floors and Walls” (https://www.jstor.org/stable/3514398?Search=yes&resultItemClick=true&searchText=%22linoleum%27%22&searchUri=%2Faction%2FdoBasicSearch%3FQuery%3D%2522linoleum%2527%26so%3Drel&ab_segments=0%2Fbasic_phrase_search%2Fcontrol&refreqid=fastly-default%3A2e3e816ffd30e6a6dcd3dc388d133299)

2 Prime Numbers = Perfect Palindrome #shorts

Usually when you look at a nice round or coordinated number, it’s components are obvious. Like 333 — you know there are 111 threes in there, and even 111 is made up of 37 threes. 1,000 is 10 hundreds, and those hundreds are 10 10’s. But when you break down 1,111,111, you find that it stems from a combination of two prime numbers that are pretty much random. How can something so perfectly symmetrical come from such weird pieces? Well, IT DOES.

El iceberg del abuso de la tecnología | RICARDO WILLIAMS | TEDxISMAC

La Academia Americana de Pediatría y la Sociedad Canadiense de Pediatría establecían antes de la pandemia, que en los niños de 3 a 5 años, el uso juegos electrónicos), debía estar limitado a 1 hora al día como máximo, mientras que los de 6 a 18 años a 2 horas, advirtiéndonos que exceder las nocivas en su desarrollo. Sin embargo la pandemia trastornó esto llegando incluso a quintuplicar ese número de horas. Los adultos tampoco escapamos y empezamos a percibir esta afectación, pero apenas estamos viendo lo sobresale de la superficie: las consecuencias más graves están ocurriendo urge que empecemos a mirar en esa profundidad. Mi nombre es Ricardo Williams y soy un compositor, autor de Santillana, conferencista y motivador ecuatoriano con una carrera de 35 años en la que he abordado temas profundos y trascendentales para la niñez, la adolescencia y la familia.

Desde la prevención del abuso sexual infantil hasta la de la violencia de género, el logro obtenido con cada uno de estos trabajos ha sido la creación de herramientas educativas y transformadoras desde el ámbito de la música, herramientas que llenan vacíos y brindan apoyo a todo aquel que la utiliza.

Producto de aquello estas herramientas han sido avaladas por importantes especialistas y profesionales, contando de igual manera con el prestigioso auspicio de NACIONES UNIDAS, ONGs y diversos organismos del Estado Ecuatoriano entre otros.

En quoi la recherche fondamentale est-elle utile ? | Julie Batut | TEDxToulouse

Qu’est-ce que la recherche fondamentale ? A quoi sert-elle ? Comment les scientifiques se servent des découvertes passées pour comprendre le vivant ? Comment les mathématiques, l’informatique et la physique peuvent se connecter à la Biologie ? La chercheuse Julie Batut présente, à travers la recherche sur l’olfaction, l’intérêt des modèles animaux et de la recherche fondamentale. ulie Batut est biologiste, spécialiste de la neurogenèse ainsi que de l’identité et de la forme des cellules au cours du développement embryonnaire. Chercheuse au CNRS, elle étudie la mise en place de l’épithélium olfactif chez l’embryon de poisson zèbre en utilisant de l’imagerie en temps réel et un modèle mathématique.

Elle est également engagée au sein de l’association Femmes & Sciences où elle développe en autre le mentorat pour les doctorantes et récemment au sein des Chemins Buissonniers et de Les Maths en scène pour transmettre ses passions, la recherche et l’embryologie, au plus grand nombre.

Hog farming has a massive poop problem

Inside North Carolina’s search for solutions for its thousands of pig manure lagoons.

Subscribe and turn on notifications 🔔 so you don’t miss any videos: http://goo.gl/0bsAjO

For this third episode of our video series with Vox’s Future Perfect team, we went to North Carolina, a state that for decades has been a battleground over the public health impact of hog farming.

​​Animal Charity Evaluators provided funding without editorial input for the production of this series.

I interviewed two people in North Carolina who do not appear in the video: Sherri White-Williamson, who heads the Environmental Justice Community Action Network, or EJCAN, a nonprofit working toward water testing in the area, particularly of private wells.

Home

I also interviewed Jeff Currie, a member of the Lumbee tribe in North Carolina, and a Waterkeeper Alliance worker whose job it is to test the Lumber River watershed for contamination. The Lumbee tribe is primarily located in Robeson County, one of the areas with a high concentration of hog farms that we cover in the video.

Who is Waterkeeper: Jefferson Currie II, Lumber Riverkeeper

Another feature of North Carolina that makes it more vulnerable to water contamination is its permeable, sandy soil in areas with a high concentration of hog farms. Experts told me this area used to be swampland, and was drained to make way for agriculture. My colleague Liz Scheltens mentions a similar historical context in a video she made about Lake Erie and cow waste pollution:

The location of hog farms in North Carolina is related to the history of tobacco farming in the state. When the public health effects of smoking became clear, the government stopped supporting it. Many North Carolina farmers started to diversify their practices, including raising hogs. That’s exactly how Tom Butler got into raising pigs — he was once a tobacco farmer:

Bright Leaves: North Carolina & Tobacco: Historical Background

Advocates and community members are also deeply concerned about the proliferation of large-scale poultry facilities in North Carolina, which accelerated when the moratorium on new or expanded hog farms was enacted in 1997:

https://www.wunc.org/environment/2020-07-30/explosive-growth-in-nc-poultry-farms-poses-grave-risks-new-report-says

The Align RNG map we show in this video, illustrating where a proposed methane pipeline might go, has been a source of heated debate in North Carolina. The Southern Environmental Law Center and other organizations have asked the state for more transparency about where the farms and the pipeline are located in order to get informed public input on the project. More details on this are in this story:

Smithfield, Dominion propose major swine gas project, but details are secret, troubling residents

We contacted Align RNG and Smithfield for this story, and they both said they sought public input for the biogas project and touted the project’s potential for cutting greenhouse gas emissions. They also said that the state of North Carolina has “stringent” permit regulations that they adhere to.

Vox’s Future Perfect team covered this issue here:
https://www.vox.com/future-perfect/2020/9/16/21430837/future-perfect-podcast-season-3-north-carolina-cafo-pig-farm

And in a podcast episode, as part of their series on meat:

A similar debate about the promises of biogas is happening in the dairy industry as well:

Are Dairy Digesters the Renewable Energy Answer or a ‘False Solution’ to Climate Change?

ProPublica has a more in-depth investigation into the Smithfield agreement:
https://www.propublica.org/article/a-hog-waste-agreement-lacked-teeth-and-some-north-carolinians-say-left-to-suffer

I learned a lot from Melba Newsome’s writing and reporting on this issue for North Carolina Health News:

Decades of legal battles over pollution by industrial hog farms haven’t changed much for eastern NC residents burdened by environmental racism

Rick Dove of the Waterkeeper Alliance manages a website that tracks this issue:

Why You Should Be Wary About Incredible Online Shopping Deals [Advertiser Content From Zelle®]

We’re always on the hunt for a perfect deal, but sometimes, scammers can exploit that desire and have us turning over our hard-earned money for a big bunch of nothing.

But why?

Because our desire for reward usually outweighs our fear of repercussions — kind of like a mouse ignoring a trap so they can get that must-have piece of cheese. When we’re presented with an incredible deal, it clouds our critical judgement, making it hard for us to say no. But usually, if a deal is too good to be true, then it probably is.

The meters-high mountain of mannequins in the Midlands

Mannequins are generally bought, used once for a project, and then thrown away to landfill. Except here, at Mannakin in Lincolnshire. Thanks to Roz and the team at Mannakin: https://mannakin.com

My first thought was “don’t those mannequins rot, just sitting out there in the weather?” And then I realised: no, not really, they’re fibreglass. That’s part of the problem Mannakin’s trying to help with!

This Forgotten Ecosystem Holds Twice as Much Carbon Than Forests

As more of the world’s forests are destroyed, it makes you wonder: what’s going to absorb CO2 in their place?! In an ironic twist of fate, one of Earth’s “deadest” habitats might be our best hope for an ongoing supply of breathable air.

Called peatlands, these wetland environments are named for their tendency to accumulate decayed plant matter. Unlike most other ecosystems, like forests, where branches and leaves typically decompose in a matter of months… in peatlands, that plant material can stay intact for millenia. You see, peatlands mostly exist in high altitude places where temps are low and there’s not much water flow. This results in their having extremely low oxygen and high acidity levels. These harsh conditions aren’t very hospitable to microbes and fungi, which are instrumental to the whole decomposition process. So without them around, the plant material sort of… just sits. Over time, that it globs together to form peat, a thick, spongy material that can soak up 20x its weight in water.

Peat also soaks up loads of carbon. Through a process known as the Calvin cycle, living plants absorb CO2 from the air and convert it into organic molecules that they can then use as energy to grow. Through decomposition, the carbon that’s “fixed” in a plant’s structure gets released but since peat doesn’t decompose, that carbon can stay put! It’s estimated that peatlands contain 550 gigatonnes of organic carbon, which is twice as much organic carbon as all the world’s forests combined. That’s absolutely wild, considering that forests cover about 30% of the world’s land area… and peatlands only account for 3%!

Like most of the world’s habitats, peatlands aren’t immune to the threats of human development and exploitation. Peat is also are a very in-demand resource. Its incredible water holding capacity makes it a favorite amongst horticulturists; If you’ve ever picked up a bag of soil amendment, chances are it’s full of the stuff. Since peat is also a fossil fuel with a long burn, it’s used in some parts of the world. Peatlands are also often drained to accommodate other land use activities, like agriculture.

The Mad Dash to Figure Out the Fate of Peatlands
https://www.smithsonianmag.com/science-nature/mad-dash-figure-out-fate-peatlands-180958841/
“Second only to the oceans in the amount of atmospheric carbon they store, peat bogs are integral to the Earth’s carbon cycle. Most peat started forming after the last ice age, roughly 12,000 years ago, and for millennia, they’ve been important carbon reservoirs.”

Europe’s Famed Bog Bodies Are Starting to Reveal Their Secrets
https://www.smithsonianmag.com/science-nature/europe-bog-bodies-reveal-secrets-180962770/
“Tollund Man is the best-looking and best-known member of an elite club of preserved cadavers that have come to be known as “bog bodies.” These are men and women (also some adolescents and a few children) who were laid down long ago in the raised peat bogs of Northern Europe—mostly Denmark, Germany, England, Ireland and the Netherlands.”

Hot New Environmental Threat: Zombie Fires That Come Back to Life
https://www.popularmechanics.com/science/environment/a36455198/what-are-zombie-fires/
“Packed deep within carbon-rich soils and insulated by feet of snow, zombie fires can smolder for months, long after firefighters have extinguished the surface flames. As the snow melts and the soil begins to dry out, flames can reignite on the surface and spark larger blazes. This poses a problem not only for people and property, but for the climate, too.”

“Laughter is NOT the best medicine,” says comedian | Mimi Hayes | TEDxCherryCreekWomen

According to Mimi Hayes, laughter is NOT the best medicine. And she should know, she’s a standup comedian with a brain injury. What’s really behind jokes made at our own expense? And are we allowed to joke about having a catheter when we wake up from brain surgery? Hayes takes us into the mind of a comedian using humor to cope with trauma and the benefits (and consequences) of making light of our darkest days. Mimi Hayes became a standup comedian after having a traumatic brain injury on a blind date. She also wrote “I’ll Be OK, It’s Just a Hole in My Head,” a humorous memoir about her diagnosis and recovery. Hayes adapted the book into a one-woman show, TV pilot, podcast, and frequently makes fun of her trauma on stages around the world. When she’s not telling jokes you’ll find her at the dog park or in therapy. You can follow her antics at mimihayes.com and on social media. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Amina J. Mohammed: A new perspective on the journey to net-zero | TED Countdown

Climate action can be a vehicle to deliver dignity, opportunity and equality for all. UN Deputy Secretary-General Amina J. Mohammed invites us to reimagine what the journey to net-zero could look like if we invest in people’s climate efforts while prioritizing the 17 Sustainable Development Goals — a blueprint of interlinked global goals to protect humanity and our warming planet. “It’s time to make some serious noise to transform our world,” she says.

Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world. Get involved at https://countdown.ted.com/sign-up

4 Mysterious Extinctions from Earth’s History

Nowadays, we’re pretty confident about how the dinosaurs died out, but there are still other extinctions throughout Earth’s history, some big, some small, that remain unsolved.

Nithya Ramanathan: The problem of vaccine spoilage — and a smart sensor to help | TED

Refrigerators do much more than store your groceries — they’re also vital to preserving and distributing vaccines. Illustrating the realities of (and threats to) global vaccine supply chains, technologist and TED Fellow Nithya Ramanathan describes how smart sensors placed in fridges that store medical supplies can provide crucial, real-time data and ensure people get the life-saving care they need.

The Surprising Reason Why You Talk in Your Sleep

Some of us sleep soundly without uttering a whisper; others deliver entire speeches while sawing their logs. But why is that…and how does sleep talking affect our health?

Many people think of sleep as the brain shutting off. Curtains. Lights out. But our brains are actually quite active during slumber. Throughout the night, we cycle through two types of sleep: Rapid Eye Movement, or REM, and non-REM, which has three stages. As we move through each stage, our brain waves progressively fall into lower frequencies and higher amplitudes until we reach deep, slow-wave sleep at stage 3.

Sleep talk can happen at any point during what scientists call “transitory arousal”, which is when a sleeper becomes half awake while transitioning from one stage to the next. Interestingly, the quality of our speech here decreases as we move closer toward stage 3. After stage 3 we enter REM sleep. This is when our eyes rapidly move behind closed lids and our brain activity becomes closer to how it is when we’re awake.

There are two different structures in the brain that control when we’re awake and when we’re asleep, sort of like a light switch. One is the Reticular Activating System, or RAS, a complex network of neurons located in the brain stem. It releases chemical messengers called neurotransmitters that promote wakefulness and help regulate our sleep-wake cycles. The other system, the Ventrolateral Preoptic Nucleus, or VLPO, is located in the hypothalamus. It releases neurotransmitters that bring on sleep by suppressing neural activity to the RAS. During REM, the VLPO structure releases powerful neurotransmitters that work together to inhibit motor neurons and prevent you from acting out your dreams of flying.

Is There a Link Between Sleepwalking, Sleep Talking, and Mental Health?
https://www.goodtherapy.org/blog/is-there-a-link-between-sleepwalking-sleep-talking-and-mental-health-1103187
“Both sleepwalking and sleep talking can happen for many reasons. Sometimes they are symptoms of a mental health condition, and both may cause psychological distress and interfere with relationships, work, and even overall life satisfaction.”

Why Do People Talk in Their Sleep?
https://www.discovermagazine.com/mind/why-do-people-talk-in-their-sleep
“The things people say depend heavily on what sleep stage they’re in. Barrett describes a gradual progression during the four stages of non-REM sleep that goes from primarily mumbling sounds and simple words in the deepest sleep of stage four, to simple phrases in stage three, and finally complete sentences that begin in stage two.”

Here’s What You Say When You Talk in Your Sleep
https://www.livescience.com/61324-what-you-say-sleep-talking.html
“In the study, researchers found that sleep talkers said the word “no” four times more often in their sleep than when awake. And the F-word popped up during sleep talking at a rate of more than 800 times than what was spoken while awake.”

Are There Infinite Infinities? #shorts

Bitdefender Total Security (Extended Free Trial) – https://www.bitdefender.com/media/html/consumer/new/WI-S-Bitdefender/?cid=inf&7Cc%7Cig¾7CVS2Q4

Thanks to Bitdefender for supporting Vsauce2.

We know what infinity is… it’s something that never ends. It’s right in the name: ‘doesn’t finish.’ But is it possible to have more than one infinity? Can one infinity be larger than another? And if we say yes or no, can we even prove it?! Over a century ago, Georg Cantor changed our conception of mathematical infinity, and we’re still trying to figure it out.

Solomon Goldstein-Rose: How much clean electricity do we really need? | TED Countdown

To fight climate change, we need to clean up the global electricity system by replacing fossil fuel power plants with clean generation — right? Climate author Solomon Goldstein-Rose thinks we need to do much more than that. Replacement isn’t enough, he explains in this compelling talk: we need to rapidly develop a new global system capable of producing 12 times the amount of clean electricity we generate today. He shares four reasons why we need that expansion — first, to electrify everything in all parts of the world (not just the wealthy ones) — as well as some intriguing ideas for how we can get there.

Countdown is TED’s global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world. Get involved at https://countdown.ted.com/sign-up

4 ways to hack your memory | Lisa Genova | Big Think

4 ways to hack your memory, with Lisa Genova
Subscribe to Big Think on YouTube ►► https://www.youtube.com/c/bigthink
Up next ►► How memory works https://youtu.be/kwo2WxM87-g

Self-testing is one good way to better remember information. Think of memory as a two-way street. If we only put information in, it is like traveling in only one direction. Recalling information requires us to go the other way.

Spacing out studying is better than cramming.If you need seven hours to prepare for an exam that is one week from today, study one hour per day rather than all seven hours the night before.

Context matters for memory recall. If you study while eating Sour Patch candy, do the same thing while taking the test.

Five YouTubers. Five games. $10,000. ⋮ Money: the full series

I invited Rohin from @Medlife Crisis, Sophie from @Soph’s Notes, @Mike Boyd, Sam from @Wendover Productions, and @Mia Mulder to play some games. They’ll be tempted by individual profit over group wealth, in an environment designed to slowly break their team apart. But all they knew is: they’d be sat around a table trying to win cash: over $10,000. This is a show about trust, about loyalty… and about Money.

This was originally a five-episode series for Nebula: for this free-to-air release, it’s been combined into a single omnibus episode. The changes are limited to: cutting the “previously on” sections; adjusting the music to cleanly bridge episodes; and combining all the credits into one end-of-the-series set.
