I will not let silence wrap itself around my indecision. I will tell Christian that he is a lion, a sanctuary of bravery and brilliance. I will ask that homeless man what his name is and how his day was, because sometimes all people want to be is human. I will tell that woman that my students can talk about transcendentalism like their last name was Thoreau, and just because you watched one episode of "The Wire" doesn't mean you know anything about my kids. So this year, instead of giving something up, I will live every day as if there were a microphone tucked under my tongue, a stage on the underside of my inhibition. Because who has to have a soapbox when all you've ever needed is your voice? Thank you. #Social_Change #Poetry #Spoken_Word 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

🟢The danger of silence Dr. Martin Luther King, Jr., in a 1968 speech where he reflects upon the Civil Rights Movement, states, "In the end, we will remember not the words of our enemies but the silence of our friends." As a teacher, I've internalized this message. Every day, all around us, we see the consequences of silence manifest themselves in the form of discrimination, violence, genocide and war. In the classroom, I challenge my students to explore the silences in their own lives through poetry. We work together to fill those spaces, to recognize them, to name them, to understand that they don't have to be sources of shame. In an effort to create a culture within my classroom where students feel safe sharing the intimacies of their own silences, I have four core principles posted on the board that sits in the front of my class, which every student signs at the beginning of the year: read critically, write consciously, speak clearly, tell your truth. And I find myself thinking a lot about that last point, tell your truth. And I realized that if I was going to ask my students to speak up, I was going to have to tell my truth and be honest with them about the times where I failed to do so. So I tell them that growing up, as a kid in a Catholic family in New Orleans, during Lent I was always taught that the most meaningful thing one could do was to give something up, sacrifice something you typically indulge in to prove to God you understand his sanctity. I've given up soda, McDonald's, French fries, French kisses, and everything in between. But one year, I gave up speaking. I figured the most valuable thing I could sacrifice was my own voice, but it was like I hadn't realized that I had given that up a long time ago. I spent so much of my life telling people the things they wanted to hear instead of the things they needed to, told myself I wasn't meant to be anyone's conscience because I still had to figure out being my own, so sometimes I just wouldn't say anything, appeasing ignorance with my silence, unaware that validation doesn't need words to endorse its existence. When Christian was beat up for being gay, I put my hands in my pocket and walked with my head down as if I didn't even notice. I couldn't use my locker for weeks because the bolt on the lock reminded me of the one I had put on my lips when the homeless man on the corner looked at me with eyes up merely searching for an affirmation that he was worth seeing. I was more concerned with touching the screen on my Apple than actually feeding him one. When the woman at the fundraising gala said "I'm so proud of you. It must be so hard teaching those poor, unintelligent kids," I bit my lip, because apparently we needed her money more than my students needed their dignity. We spend so much time listening to the things people are saying that we rarely pay attention to the things they don't. Silence is the residue of fear. It is feeling your flaws gut-wrench guillotine your tongue. It is the air retreating from your chest because it doesn't feel safe in your lungs. Silence is Rwandan genocide. Silence is Katrina. It is what you hear when there aren't enough body bags left. It is the sound after the noose is already tied. It is charring. It is chains. It is privilege. It is pain. There is no time to pick your battles when your battles have already picked you.

Viruses are slippery beasts. We have, though, had some incredible successes: we eradicated smallpox thanks to an effective vaccine, the fact that it can’t hide out in other species, and its relatively low mutation rate. HIV, on the other hand, mutates so quickly that in an untreated individual, every possible single-letter mutation in the virus’s genetic code could, in theory, be produced in a single day. Despite trying for decades, we still don’t have a vaccine. But we do have an effective cocktail of HIV drugs that the virus can’t easily mutate away from. Unfortunately, we are stuck with colds for now. But the last few decades have featured some entirely game-changing medical breakthroughs, like mRNA vaccines and CRISPR. CRISPR could be particularly promising as an antiviral agent, because it originally evolved in bacteria as an immune defense against viruses. In fact, early in the COVID-19 pandemic, a research team showed that a CRISPR system could degrade coronavirus and influenza genomes in our lung cells. They called their system prophylactic antiviral CRISPR in human cells. #Education #Disease #Health #Health_Care #Medicine #Illness #Vaccines #Virus #Medical_Research #TED_Ed #Animation #Human_Body #Coronavirus 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

🟢Why is it so hard to cure the common cold? In 2000, a company called ViroPharma ran clinical trials of pleconaril, a new pill designed to treat the common cold. In many patients, the pill helped. But in 7 of them, just a few days into the treatment, researchers found mutated virus variants that were almost completely resistant to pleconaril. Viruses are always mutating, but this one mutated so quickly that it managed to outmaneuver years of research and development in just a few days. If you didn't have an immune system and caught a cold, the infection would quickly spread deep into your lungs. Rampant viral replication would destroy tissue there, until your lungs couldn’t supply your body with enough oxygen and you’d asphyxiate. Unfortunately, for millions of people around the world who live with a less-than-fully-functional immune system or who are on immunosuppressant drugs, this is a real risk: “minor” infections can turn serious or even deadly. But if you're fortunate enough to have a fully functional immune system, a cold will probably give you a few relatively mild symptoms. On average, adults catch more than 150 colds throughout their lives. And despite the fact that the symptoms are similar, the cause could be different each time Common colds are caused by at least 8 different families of virus, each of which can have its own species and subtypes. How can so many different viruses cause the same illness? Well, viruses can only invade our bodies in a few ways: one is to come in on a breath. We have to breathe, so our immune system sets up a bunch of frontline defenses and these are actually what produce many of the symptoms of a cold. Your mucus-y, dripping nose is your immune system trapping and flushing out virus. Your fever is your immune system raising your body temperature to slow down viral replication. And your inflamed, well, everything, that’s your immune system widening your blood vessels and recruiting its white blood cell army to help kill the virus. So, if the common cold is caused by many different viruses, is a cure even possible? Here’s one fact in our favor: a single family of viruses causes 30 to 50% of all colds: rhinovirus. If we could eliminate all rhinovirus infections, we’d be a long way towards curing the common cold. There are two main ways to fight a virus: vaccines and antiviral drugs. The first attempt to create a rhinovirus vaccine was a success— but a short-lived one. In 1957, William Price vaccinated 50 kids with inactivated rhinovirus and gave 50 others a placebo. Soon afterwards, a rhinovirus outbreak spread throughout the kids. In the vaccinated group, only 3 got sick. In the placebo group, 23 did— almost 8 times as many. And despite the small numbers, this was promising: the immune systems of vaccinated kids were successfully recognizing and responding to rhinovirus. But later trials of the vaccine showed no protection at all— none. This wasn’t Price’s fault— no one at the time knew that rhinovirus had multiple subtypes. Price’s vaccine, for reasons we don’t fully understand, didn't provide broad protection, meaning it was only effective against one or maybe a few subtypes of rhinovirus— out of 169 subtypes and counting. Sometimes, when we make a vaccine, we get lucky. The mRNA COVID vaccines, for example, effectively protect us against severe disease and death across the original virus and variants too. But we have yet to create a broadly protective vaccine against rhinovirus, or any other virus that causes the common cold. Okay, what about antiviral drugs? Viruses hijack human cellular machinery to replicate and spread, so it’s hard to make a molecule that’s toxic to the virus without also being toxic to the human. And even if you manage to do that, the virus could mutate out of reach of the drug.

And then there's social media. I can imagine some pretty frickin' dystopian scenarios where things like internet quizzes, dating apps, horoscopes, bots, all combine to drag you down deeper and deeper rabbit holes into bad relationships and worse politics. But then I think about the conversations that I've had with people who work on AI, and what I always hear from them is that the smarter AI gets, the better it is at making connections. So maybe the social media of the future will be better. Maybe it'll help us to form healthier, less destructive relationships. Maybe we'll have devices that enable togetherness and serendipity. I really hope so. And, you know, I like to think that if strong AI ever really exists, they'll probably enjoy our weird relationship drama the same way that you and I love to obsess about the "Real Housewives of Wherever." And finally, there's medicine. I think a lot about how developments in genetic medicine could improve outcomes for people with cancer or dementia, and maybe one day, your hundredth birthday will be just another milestone on the way to another two or three decades of healthy, active life. Maybe the toilet of the future that I mentioned will improve health outcomes for a lot of people, including people in parts of the world where they don't have these complicated sewer systems that I mentioned. But also, as a transgender person, I like to think: What if we make advances in understanding the endocrine system that improve the options for trans people, the same way that hormones and surgeries expanded the options for the previous generation? So finally: basically, I'm here to tell you, people talk about the future as though it's either going to be a technological wonderland or some kind of apocalyptic poop barbecue. (Laughter) But the truth is, it's not going to be either of those things. It's going to be in the middle. It's going to be both. It's going to be everything. The one thing we do know is that the future is going to be incredibly weird. Just think about how weird the early 21st century would appear to someone from the early 20th. And, you know, there's a kind of logical fallacy that we all have where we expect the future to be an extension of the present. Like, people in the 1980s thought that the Soviet Union would still be around today. But the future is going to be much weirder than we could possibly dream of. But we can try. And I know that there are going to be scary, scary things, but there's also going to be wonders and saving graces. And the first step to finding your way forward is to let your imagination run free. Thank you. #Science_Fiction #Future #Creativity #Society #Writing #Storytelling 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

So as a storyteller, first and foremost, I try to live in the world through the eyes of my characters and try to see how they navigate their own personal challenges in the context of the space that I've created. What do they smell? What do they touch? What's it like to fall in love inside a smart city? What do you see when you look out your window, and does it depend on how the window's software interacts with your mood? And finally, I ask myself how a future brilliant city would ensure that nobody is homeless and nobody slips through the cracks. And here's where future history comes in handy, because cities don't just spring up overnight like weeds. They arise and transform. They bear the scars and ornaments of wars, migrations, economic booms, cultural awakenings. A future city should have monuments, yeah, but it should also have layers of past architecture, repurposed buildings and all of the signs of how we got to this place. And then there's second-order effects, like how do things go wrong -- or right -- in a way that nobody ever anticipated? Like, if the walls of your apartment are made out of a kind of fungus that can regrow itself to repair any damage, what if people start eating the walls? (Laughter) Speaking of eating: What kind of sewer system does the city of the future have? It's a trick question. There are no sewers. There's something incredibly bizarre about the current system we have in the United States, where your waste gets flushed into a tunnel to be mixed with rainwater and often dumped into the ocean. Not to mention toilet paper. A bunch of techies, led by Bill Gates, are trying to reinvent the toilet right now, and it's possible that the toilet of the future could appear incredibly strange to someone living today. So how does the history of the future, all of that trial and error, lead to a better way to go to the bathroom? There are companies right now who are experimenting with a kind of cleaning wand that can substitute for toilet paper, using compressed air or sanitizing sprays to clean you off. But what if those things looked more like flowers than technology? What if your toilet could analyze your waste and let you know if your microbiome might need a little tune-up? What if today's experiments with turning human waste into fuel leads to a smart battery that could help power your home? But back to the city of the future. How do people navigate the space? If there's no streets, how do people even make sense of the geography? I like to think of a place where there are spaces that are partially only in virtual reality that maybe you need special hardware to even discover. Like for one story, I came up with a thing called "the cloudscape interface," which I described as a chrome spider that plugs into your head using temporal nodes. No, that's not a picture of it, but it's a fun picture I took in a bar. (Laughter) And I got really carried away imagining the bars, restaurants, cafés that you could only find your way inside if you had the correct augmented reality hardware. But again, second-order effects: in a world shaped by augmented reality, what kind of new communities will we have, what kind of new crimes that we haven't even thought of yet? OK, like, let's say that you and I are standing next to each other, and you think that we're in a noisy sports bar, and I think we're in a highbrow salon with a string quartet talking about Baudrillard. I can't possibly imagine what might go wrong in that scenario. Like, it's just -- I'm sure it'll be fine.

🟢Go ahead, dream about the future Every science fiction writer has a story about a time when the future arrived too soon. I have a lot of those stories. Like, OK, for example: years ago, I was writing a story where the government starts using drones to kill people. I thought that this was a really intense, futuristic idea, but by the time the story was published, the government was already using drones to kill people. Our world is changing so fast, and there's a kind of accelerating feedback loop where technological change and social change feed on each other. When I was a kid in the 1980s, we knew what the future was going to look like. It was going to be some version of "Judge Dredd" or "Blade Runner." It was going to be neon megacities and flying vehicles. But now, nobody knows what the world is going to look like even in just a couple years, and there are so many scary apparitions lurking on the horizon. From climate catastrophe to authoritarianism, everybody is obsessed with apocalypses, even though the world ends all the time, and we keep going. Don't be afraid to think about the future, to dream about the future, to write about the future. I've found it really liberating and fun to do that. It's a way of vaccinating yourself against the worst possible case of future shock. It's also a source of empowerment, because you cannot prepare for something that you haven't already visualized. But there's something that you need to know. You don't predict the future; you imagine the future. So as a science fiction writer whose stories often take place years or even centuries from now, I've found that people are really hungry for visions of the future that are both colorful and lived in, but I found that research on its own is not enough to get me there. Instead, I use a mixture of active dreaming and awareness of cutting-edge trends in science and technology and also insight into human history. I think a lot about what I know of human nature and the way that people have responded in the past to huge changes and upheavals and transformations. And I pair that with an attention to detail, because the details are where we live. We tell the story of our world through the tools we create and the spaces that we live in. And at this point, it's helpful to know a couple of terms that science fiction writers use all of the time: "future history" and "second-order effects." Now, future history is basically just what it sounds like. It is a chronology of things that haven't happened yet, like Robert A. Heinlein's famous story cycle, which came with a detailed chart of upcoming events going up into the year 2100. Or, for my most recent novel, I came up with a really complicated time line that goes all the way to the 33rd century and ends with people living on another planet. Meanwhile, a second-order effect is basically the kind of thing that happens after the consequences of a new technology or a huge change. There's a saying often attributed to writer and editor Frederik Pohl that "A good science fiction story should predict not just the invention of the automobile, but also the traffic jam." And speaking of traffic jams, I spent a lot of time trying to picture the city of the future. What's it like? What's it made of? Who's it for? I try to picture a green city with vertical farms and structures that are partially grown rather than built and walkways instead of streets, because nobody gets around by car anymore -- a city that lives and breathes. And, you know, I kind of start by daydreaming the wildest stuff that I can possibly come up with, and then I go back into research mode, and I try to make it as plausible as I can by looking at a mixture of urban futurism, design porn and technological speculation. And then I go back, and I try to imagine what it would actually be like to be inside that city. So my process kind of begins and ends with imagination, and it's like my imagination is two pieces of bread in a research sandwich

So here's how it looks from a banana-peel-universe point of view, from my mindset, which I call "Emily's universe." First of all, I am incredibly grateful for life, but I don't want to be immortal. I have no interest in having my name live on after me. In fact, I don't want it to, because it's been my observation that no matter how nice and how brilliant or how talented you are, 50 years after you die, they turn on you. And I have actual proof of that. A headline from the Los Angeles Times: "Anne Frank: Not so nice after all." Plus, I love being in sync with the cyclical rhythms of the universe. That's what's so extraordinary about life: it's a cycle of generation, degeneration, regeneration. "I" am just a collection of particles that is arranged into this pattern, then will decompose and be available, all of its constituent parts, to nature, to reorganize into another pattern. To me, that is so exciting, and it makes me even more grateful to be part of that process. You know, I look at death now from the point of view of a German biologist, Andreas Weber, who looks at it as part of the gift economy. You're given this enormous gift, life, you enrich it as best you can, and then you give it back. And, you know, Auntie Mame said, "Life is a banquet" -- well, I've eaten my fill. I have had an enormous appetite for life, I've consumed life, but in death, I'm going to be consumed. I'm going into the ground just the way I am, and there, I invite every microbe and detritus-er and decomposer to have their fill. I think they'll find me delicious. So the best thing about my attitude, I think, is that it's real. You can see it. You can observe it. It actually happens. Well, maybe not my enriching the gift, I don't know about that -- but my life has certainly been enriched by other people. By TED, which introduced me to a whole network of people who have enriched my life, including Tricia McGillis, my website designer, who's working with my wonderful daughter to take my website and turn it into something where all I have to do is write a blog. I don't have to use the executive brain function ... Ha, ha, ha, I win! And I am so grateful to you. I don't want to say "the audience," because I don't really see it as we're two separate things. I think of it in terms of quantum physics, again. And, you know, quantum physicists are not exactly sure what happens when the wave becomes a particle. There are different theories -- the collapse of the wave function, decoherence -- but they're all agreed on one thing: that reality comes into being through an interaction. (Voice breaking) So do you. And every audience I've ever had, past and present. Thank you so much for making my life real. #Aging #Cancer #Comedy #Death #Creativity #Happiness #Humanity #Humor #Illness 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

But what I do want to talk about is a personal challenge to reality that I take personally, and I want to preface it by saying that I absolutely love science. I have this -- not a scientist myself -- but an uncanny ability to understand everything about science, except the actual science -- which is math. But the most outlandish concepts make sense to me. The string theory; the idea that all of reality emanates from the vibrations of these teeny -- I call it "The Big Twang." Wave-particle duality: the idea that one thing can manifest as two things ... you know? That a photon can manifest as a wave and a particle coincided with my deepest intuitions that people are good and bad, ideas are right and wrong. Freud was right about penis envy and he was wrong about who has it. And then there's this slight variation on that, which is reality looks like two things, but it turns out to be the interaction of those two things, like space -- time, mass -- energy and life and death. So I don't understand -- I simply just don't understand the mindset of people who are out to "defeat death" and "overcome death." How do you do that? How do you defeat death without killing off life? It doesn't make sense to me. I also have to say, I find it incredibly ungrateful. I mean, you're given this extraordinary gift -- life -- but it's as if you had asked Santa for a Rolls-Royce Silver Shadow and you had gotten a salad spinner instead. You know, it's the beef -- the beef with it is that it comes with an expiration date. Death is the deal breaker. I don't get that. I don't understand -- to me, it's disrespectful. It's disrespectful to nature. The idea that we're going to dominate nature, we're going to master nature, nature is too weak to withstand our intellect -- no, I don't think so. I think if you've actually read quantum physics as I have -- well, I read an email from someone who'd read it, but -- You have to understand that we don't live in Newton's clockwork universe anymore. We live in a banana peel universe, and we won't ever be able to know everything or control everything or predict everything. Nature is like a self-driving car. The best we can be is like the old woman in that joke -- I don't know if you've heard it. An old woman is driving with her middle-aged daughter in the passenger seat, and the mother goes right through a red light. And the daughter doesn't want to say anything that makes it sound like, "You're too old to drive," so she didn't say anything. And then the mother goes through a second red light, and the daughter, as tactfully as possible, says, "Mom, are you aware that you just went through two red lights?" And the mother says, "Oh, am I driving?" So ... and now, I'm going to take a mental leap, which is easy for me because I'm the Evel Knievel of mental leaps; my license plate says, "Cogito, ergo zoom." I hope you're willing to come with me on this, but my real problem with the mindset that is so out to defeat death is if you're anti-death, which to me translates as anti-life, which to me translates as anti-nature, it also translates to me as anti-woman, because women have long been identified with nature. And my source on this is Hannah Arendt, the German philosopher who wrote a book called "The Human Condition." And in it, she says that classically, work is associated with men. Work is what comes out of the head; it's what we invent, it's what we create, it's how we leave our mark upon the world. Whereas labor is associated with the body. It's associated with the people who perform labor or undergo labor. So to me, the mindset that denies that, that denies that we're in sync with the biorhythms, the cyclical rhythms of the universe, does not create a hospitable environment for women or for people associated with labor, which is to say, people that we associate as descendants of slaves, or people who perform manual labor.

🟢How I made friends with reality? I'm going to first tell you something that in my grandmother would've elicited a five-oy alarm: "Oy-oy-oy-oy-oy." And here it is ... are you ready? OK. I have stage IV lung cancer. Oh, I know, "poor me." I don't feel that way. I'm so OK with it. And granted, I have certain advantages -- not everybody can take so cavalier an attitude. I don't have young children. I have a grown daughter who's brilliant and happy and wonderful. I don't have huge financial stress. My cancer isn't that aggressive. It's kind of like the Democratic leadership -- not convinced it can win. It's basically just sitting there, waiting for Goldman Sachs to give it some money. Oh, and the best thing of all -- I have a major accomplishment under my belt. Yes. I didn't even know it until someone tweeted me a year ago. And here's what they said: "You are responsible for the pussification of the American male." Not that I can take all the credit, but ... But what if you don't have my advantages? The only advice I can give you is to do what I did: make friends with reality. You couldn't have a worse relationship with reality than I did. From the get-go, I wasn't even attracted to reality. If they'd had Tinder when I met reality, I would have swiped left and the whole thing would have been over. And reality and I -- we don't share the same values, the same goals -- To be honest, I don't have goals; I have fantasies. They're exactly like goals but without the hard work. I'm not a big fan of hard work, but you know reality -- it's either push, push, push, push, push through its agent, the executive brain function -- one of the "yays" of dying: my executive brain function won't have me to kick around anymore. But something happened that made me realize that reality may not be reality. So what happened was, because I basically wanted reality to leave me alone -- but I wanted to be left alone in a nice house with a Wolf range and Sub-Zero refrigerator ... private yoga lessons -- I ended up with a development deal at Disney. And one day I found myself in my new office on Two Dopey Drive -- And I'm staring at the present they sent me to celebrate my arrival -- not the Lalique vase or the grand piano I've heard of other people getting, but a three-foot-tall, stuffed Mickey Mouse with a catalog, in case I wanted to order some more stuff that didn't jibe with my aesthetic. And when I looked up in the catalog to see how much this three-foot-high mouse cost, here's how it was described ... "Life-sized." And that's when I knew. Reality wasn't "reality." Reality was an imposter. So I dived into quantum physics and chaos theory to try to find actual reality, and I've just finished a movie -- yes, finally finished -- about all that, so I won't go into it here, and anyway, it wasn't until after we shot the movie, when I broke my leg and then it didn't heal, so then they had to do another surgery a year later, and then that took a year -- two years in a wheelchair, and that's when I came into contact with actual reality: limits. Those very limits I'd spent my whole life denying and pushing past and ignoring were real, and I had to deal with them, and they took imagination, creativity and my entire skill set. It turned out I was great at actual reality. I didn't just come to terms with it, I fell in love. And I should've known, given my equally shaky relationship with the zeitgeist ... I'll just say, if anyone is in the market for a Betamax I should have known that the moment I fell in love with reality, the rest of the country would decide to go in the opposite direction. But I'm not here to talk about Trump or the alt-right or climate-change deniers or even the makers of this thing, which I would have called a box, except that right here, it says, "This is not a box." They're gaslighting me.

This is how the Internet works. This is that great big secret. The Internet provides a level playing field. Your link is as good as your link, which is as good as my link. With a browser, anyone can get to any website no matter your budget. That is, as long as you can keep net neutrality in place. Another important thing is it costs nothing to get content online. There are so many publishing tools available, it only takes a few minutes to produce something. and the cost of iteration is so cheap, you might as well. If you do, be genuine. Be honest, up-front. One of the great lessons Greenpeace learned is that it's OK to lose control, OK to take yourself a little less seriously, given that, even though it's a very serious cause, you could ultimately achieve your goal. That's the final message I want to share: you can do well online. But no longer is the message coming from just the top down. If you want to succeed you've got to be OK to lose control.

🟢How to make a splash in social media? There are a lot of web 2.0 consultants who make a lot of money. In fact, they make their living on this stuff. I'm going to try to save you all the time and money and go through it in the next three minutes, so bear with me. Started a website in 2005 with a few friends, called Reddit.com. It's what you'd call a social news website; basically, the democratic front page of the best stuff on the web. You find some interesting content -- say, a TED Talk -- submit it to Reddit, and a community of your peers votes up if they like it, down if they don't. That creates the front page. It's always rising, falling; a half million people visit every day. But this isn't about Reddit. It's about discovering new things that pop up on the web. In the last four years, we've seen all kinds of memes, all kinds of trends get born right on our front page. This isn't about Reddit itself, it's actually about humpback whales. Well, technically, it's about Greenpeace, an environmental organization that wanted to stop the Japanese government's whaling campaign. The whales were getting killed; they wanted to put an end to it. One of the ways they wanted to do it was to put a tracking chip inside one of the whales. But to personify the movement, they wanted to name it. So in true web fashion, they put together a poll, where they had a bunch of very erudite, very thoughtful, cultured names. I believe this is the Farsi word for "immortal." I think this means "divine power of the ocean" in a Polynesian language. And then there was this: "Mister Splashy Pants." And this was a special name. Mister Pants, or "Splashy" to his friends, was very popular on the Internet. In fact, someone on Reddit thought, "What a great thing, we should all vote this up." And Redditors responded and all agreed. So the voting started. We got behind it ourselves; we changed our logo for the day, from the alien to Splashy, to help the cause. And it wasn't long before other sites like Fark and Boing Boing and the rest of the Internet started saying, "We love Splashy Pants!" So it went from about five percent, which was when this meme started, to 70 percent at the end of voting. Pretty impressive, right? We won! Mister Splashy Pants was chosen. Just kidding -- Greenpeace actually wasn't that crazy about it, because they wanted one of the more thoughtful names to win. They said, "No, just kidding. We'll give it another week of voting." Well, that got us a little angry, so we changed it to Fightin' Splashy. And the Reddit community -- really, the rest of the Internet, really got behind this. Facebook groups were created. Facebook applications were created. The idea was, "Vote your conscience, vote for Mister Splashy Pants." People were putting up signs in the real world about this whale. This was the final vote: 78 percent of the votes. To give you an idea of the landslide, the next highest name pulled in three. There was a clear lesson: the Internet loves Mister Splashy Pants. Which is obvious. It's a great name. Everyone wants to hear their news anchor say, "Mister Splashy Pants." I think that's what helped drive this. What was cool were the repercussions. Greenpeace created an entire marketing campaign around it -- Mister Splashy Pants shirts and pins, an e-card so you could send your friend a dancing Splashy. But even more important was that they accomplished their mission. The Japanese government called off their whaling expedition. Mission accomplished: Greenpeace was thrilled, the whales were happy -- that's a quote. And actually, Redditors in the Internet community were happy to participate, but they weren't whale lovers. A few, certainly, but we're talking about a lot of people, really interested and caught up in this meme. Greenpeace came back to the site and thanked Reddit for its participation. But this wasn't really altruism; just interest in doing something cool.

The good news is there's treatment for anxiety, and that you don't have to suffer. Remember, this isn't about weakness. It's about changing brain patterns, and research shows that our brains have the ability to reorganize and form new connections all throughout our lives. A good first step is to do the basics. Eat a balanced diet, exercise regularly and get plenty of sleep, as your mind is part of your body. It might also help to try meditation. Instead of our heart rate rising and our body tensing, with mindfulness and breathing, we can slow down the fight-or-flight response and improve how we feel in the moment. Cognitive behavioral therapy, a form of talk therapy, can also be fantastic. In it, you learn to identify upsetting thoughts and determine whether they're realistic. Over time, cognitive behavioral therapy can rebuild those neural pathways that tamp down the anxiety response. Medication can also give relief, in both the short-term and the long-term. In the short-term, anti-anxiety drugs can down-regulate the threat-detection mechanisms that are going into overdrive. Studies have shown that both long-term medications and cognitive behavioral therapy can reduce that overreactivity of the amygdala we see an anxiety disorders. High blood pressure and diabetes, they can be treated or managed over time. And the same is true for an anxiety disorder too. #Psychology #Biology #Brain #Mental_Health #Neuroscience #Human_Body 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜

🟢What's normal anxiety -- and what's an anxiety disorder? We live in a culture that doesn't take mental health issues seriously. There's a lot of stigma. Some people tell you to just suck it up, or get it together, or to stop worrying, or that it's all in your head. But I'm here to tell you that anxiety disorders, they're as real as diabetes. Hi again. It's Dr. Jen, and I've noticed something with my patients. They often describe to me some classic symptoms of an anxiety disorder. Constant worry, trouble sleeping, tense muscles and struggle with concentrating. But they aren't getting treatment. There's a lot of issues with mental-health care in this country. Some people don't have insurance that would cover it. Some have been dismissed or minimized in the past, and don't think seeking help will do any good. Some worry about the stigma and whether it could affect future jobs or relationships. But severe anxiety isn't a moral or personal failing. It's a health problem, just like strep throat or diabetes. It needs to be treated with the same kind of seriousness. Before we can talk about anxiety disorders, let's talk about anxiety itself. Anxiety is the very real and normal emotion we feel in a stressful situation. It's related to fear. But while fear is a response to an immediate threat that quickly subsides, anxiety is a response to more uncertain threats that tends to last much longer. It's all part of the threat detection system, which all animals have to some degree, to help protect us from predators. Anxiety starts in the brain's amygdala, a pair of almond-sized nerve bundles that alert other areas of the brain to be ready for defensive action. Next, the hypothalamus relays the signal, setting off what we call the stress response in our body. Our muscles tense, our breathing and heart rate increase and our blood pressure rises. Areas in the brain stem kick in and put you in a state of high alertness. This is the fight-or-flight response. There are ways the fight-or-flight response is kept somewhat in check, with an area of higher-level thinking called the ventromedial prefrontal cortex. It works like this. If a person sees something they think is dangerous, like a tiger, that sends a signal to the amygdala, saying "it's time to run." The ventromedial prefrontal cortex can say to the amygdala, "Hey, look. The tiger's in a cage. You know what a cage is? They can't escape from a cage. It's OK to calm down." It's a feedback loop that can help keep the response in check. The hippocampus is also involved. It provides context, saying things like, "Hey, we've seen tigers in cages before. We're in a zoo. You are extra safe." With anxiety, these threat-detection systems and mechanisms that reduce or inhibit them are functioning incorrectly and cause us to worry about the future and our safety in it. But for many people, it goes into overdrive. They experience persistent pervasive anxiety that disrupts work, school and relationships and leads them to avoid situations that may trigger symptoms. Anxiety disorders are not at all uncommon. Based on data from the World Mental Health Survey, researchers estimate that about 16 percent of individuals currently have or have had an anxiety disorder. These include social anxiety disorder, panic disorder, agoraphobia and phobias. Studies have shown that people with anxiety disorders don't just have a different way of reacting to stress. There may be actual differences in how their brain is working. One model describes possible mix-ups in the connections between the amygdala and other parts of the brain. The pathways that signal anxiety become stronger. And the more anxiety you have, the stronger the pathways become, and it becomes a vicious cycle.
