🟢Why you don't need 8 glasses of water a day? You know that whole thing about drinking eight glasses of water a day? Sorry to have to tell you this, but it's a myth. It won't make your skin brighter, it won't make you feel clearheaded, it won't make you feel more energetic. It might, however, make you have to pee a lot. Many people don't understand the biology behind their bodies. There's a lot of misinformation out there. But the truth is that when you understand how your systems function, you're able to make better decisions. You're not as prone to fall for hype or pseudoscience. You'll feel empowered to understand what's really going on. One myth that really bugs me is the idea that you need eight glasses of water a day. Honestly, it's pretty shocking how ingrained it is. You hear it on TV, you see it in articles. But like I said, it's nonsense. For the most part, your body will tell you when you need to drink water, because you've got these wonderful, amazing, undervalued things -- kidneys. Kidneys are the bean-shaped organs located to either side of your spine, right below your ribs. They're often thought of as a filter or a waste-removal system, but that doesn't do the kidneys justice. Your body is an environment where everything, fluid and chemicals, needs to be in a delicate balance. The kidneys do a lot of the heavy lifting when it comes to this balance. Every day, blood in your body passes through the kidneys. What you eat, drink, the temperature around you, how much you exercise -- all of this affects what's going on with your body. Your kidneys, along with your nervous system and various hormones, are constantly watching many gauges and making adjustments about fluid, salt and levels of other substances in real time. They do this with about one million tiny structures called nephrons. These nephrons are kind of like workers on a conveyor belt, actively adding things and taking things away, things like sodium, glucose or sugar, calcium, amino acids and water, to make sure the body maintains homeostasis, or balance. If levels of anything get too high or too low, then that can be harmful. And it is the job of the kidneys to keep the levels of many of these substances in the just-right zone. Substances that aren't needed leave the kidney and head to the bladder, where you excrete them in the form of urine. So where do eight glasses of water a day fit in? They don't. Noticed that I did not say that the kidney function is improved with excess water. Imagine that you're sweating a lot, so you're losing water from your blood. The kidneys know your blood volume is dropping ever so slightly and that your blood is getting ever so slightly saltier. They compensate by absorbing more water back into the blood, making the urine more concentrated. If the kidneys sense enough fluid can't be reabsorbed from the urine, you're signaled to drink, meaning you get thirsty. If you don't have fluid available, the thirst message gets stronger and stronger. A person facing real dehydration won't be unsure if they need water. They'll do whatever they need to get it. It's one of our most basic instincts that's evolved over a very long time, in environments where clean water wasn't nearly as readily available as it is today.

🟢The Bug That Poops Candy This is Mabel. Mabel is an aphid, a small insect in the same order as cicadas, stink bugs, and bed bugs. All these bugs pierce their prey and suck out vital fluids. Aphids’ prey are plants. And what aphids are after is buried within the plant, flowing in tubes made from single cells strung end-to-end. These are called sieve tubes and together they form the plumbing system for a plant’s most valuable resource: sap. Sap is mostly water and sugar. Some species’ sap has as much sugar per liter as a can of soda. Photosynthesis is constantly producing sugar. You can think of it as a chemical “pump” which generates incredibly high pressure— up to 9 times that of a car tire— in the sieve tubes. To feed, Mabel uses her stylet, which is a long, flexible needle. She slowly worms it into the tissue, between the plant’s cells, until she pierces one of those sieve tubes. Because the sap is under so much pressure, Mabel doesn’t even have to suck it out of the plant. She just opens a valve in her head and lets the pressure push the sap through her digestive system. We’ll come back to what comes out of her butt, but for now, you should know that plants don’t want to be punctured and sipped. So they try to defend themselves. One defense is the sap itself. To see how that works, let’s hypothetically hook up some other insect’s digestive tract to a steady stream of sap. When that sap touches the insect’s cells, its high sugar content encourages the water in the cells to come out by osmosis… exactly like salt encourages water to come out of a slug. The more sap that passes through the insect, the more water it loses. Eventually, it shrivels up and dies. Mabel’s gut, however, is packed with an enzyme called sucrase, which takes two molecules of sucrose and converts them into one molecule of fructose and one of… this three-unit sugar. Mabel burns the fructose for energy, leaving the three-unit-sugar behind. Now, how does that help her? The more molecules of sugar that are dissolved in the sap, the more water it can suck out of Mabel’s cells. By reducing the number of molecules of sugar in the sap, Mabel reduces its ability to suck water out of her cells. Plant sap neutralized. Now that means Mabel can feed for days, getting all the energy she needs to reproduce. Some aphid species have an incredible life cycle. For example, the green peach aphid. During the fall, males and females mate, and the females lay eggs. But in the spring, when the eggs hatch, all the nymphs that emerge are female. When those females reach maturity, they don’t lay eggs. Instead, they give birth to live young… that are clones of themselves… and already pregnant… with their own clones. So, these female aphids have two generations of baby aphid clones forming inside themselves at the same time. Scientists call this telescopic development. That means that aphids can make more of themselves fast— there can be 20 generations within a single season— and that means lots of aphid poop. Mabel can poop her entire body weight every two hours, making her one of the most prolific poopers on the planet. Some aphid populations can produce hundreds of kilograms of poop per acre. Now, aphid poop is not like your poop. Chemically, it’s not all that different from sap; it’s a clear and colorless sweet, syrupy liquid. You might already know it by a different name: honeydew. Other species love honeydew. Some species of ants love it so much they sort of herd and defend entire aphid colonies. In return, the ants get a steady supply of sweet honeydew, which they can drink directly from the aphids’ butts. Bottom’s up! Humans love honeydew, too. Several Native American tribes used to harvest it from tall reeds and make it into cake. And some species of bee make honey from honeydew, which humans then harvest and eat. #Education #TED_Ed #Animation #Insects #Biology #Plants #Nature #Food 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜ 🤖اموزش رایگان زبان از طریق بات تلگرام

وقتی برخی افراد شروع به یادگیری یک زبان جدید می‌کنند، اغلب آن را با اولین زبان خارجی که می‌دانند مقایسه می‌کنند. به عنوان مثال، اگر کسی زبان انگلیسی را به عنوان زبان دوم خود بداند و شروع به یادگیری زبان‌هایی مثل آلمانی، سوئدی، هلندی یا فرانسه کند، معمولاً این زبان جدید را با انگلیسی مقایسه می‌کند. گاهی اوقات شکایت می‌کنند که این زبان سخت است، چون کاملاً مشابه انگلیسی نیست. البته که مشابه نیست! زبان‌ها از هم متفاوت هستند. یادگیری زبان مثل یادگیری یک مهارت است؛ مثل مقایسه یادگیری پیانو با آشپزی. هر زبان ساختار، دستور زبان و واژگان منحصر به فرد خود را دارد. بنابراین وقتی شروع به یادگیری زبان می‌کنید، فقط به تمرین کردن فکر کنید و شکایت نکنید. هیچ زبانی آن‌قدر ساده نیست که در دو ماه یاد گرفته شود یا آن‌قدر سخت که نتوان در یک یا دو سال یاد گرفت. تمرین، تمرین و تمرین به جای شکایت، بهترین راه است. لطفا این پست رو برای دوستانت که ممکنه یه روزی بخوان زبان دوم خارجه یاد بگیرند ارسال کن. 🙏🤝❤️

🟢How puberty changes your brain? While we often talk about puberty’s effect on the body, what gets overlooked are the fascinating changes that happen in the brain. I’ve been sent here to talk to you about puberty. Any questions? During puberty, your reproductive organs grow and mature. Any questions? This ripening allows you to become a sexually mature adult. There are so many other changes to your body that puberty can seem almost magical. I think I'll take it from here. Puberty, in fact, begins in the brain. At some point, usually between the ages of 9 and 14, puberty is triggered when a region known as the hypothalamus releases waves of a specialized hormone. As convenient as it would be to go to sleep a child and wake up an adult, this maturation is slow, and puberty lasts as long as 4 to 5 years. And during this extended process, the brain undergoes its own transformation, thanks to two of puberty’s key players— estrogen and testosterone. Produced in the developing testes and ovaries, these hormones hitch a ride to the brain via the bloodstream. Once there, they interact with receptors on neurons, changing the way the individual cells work and function by making them more or less excitable, altering their growth, or reshaping their connections. Cumulatively, this can change how you feel, think, and behave. For example, hormones remodel and develop the limbic system, a collection of brain regions responsible for emotional behavior. Research in animal models suggests that the amygdala undergoes changes in size and connectivity during puberty. The amygdala’s function is wide-ranging, from detecting threats in your environment, to helping you recognize emotions in your friend’s faces. Its development allows you to better connect with your peers, while priming your brain for learning and discovery. Likewise, puberty organizes and restructures the nucleus accumbens involved in reward and sensation-seeking. Activity in this dopamine hub is thought to drive the pleasurable sensations we feel when doing rewarding activities, like spending time with friends or having new experiences. Several studies have found that as hormone levels increase through puberty, so does the response of the nucleus accumbens. As a result, exploration and social engagement may feel that much more important during adolescence. As these emotion and reward centers rapidly develop, their connections with higher cortical brain regions tend to do so on an extended timeline. These cortical regions, which help impose emotional regulation and impulse control, continue to grow well past puberty, into your 20s. While teens are often unfairly stereotyped as rash or impulsive, research reveals a more complex story. Teens are just as capable as adults of making thoughtful decisions when given the time and space. It’s only during high stress or in the heat of the moment that teens may find it more difficult to manage emotions. Further, this lengthy cortical development allows adolescent brains to remain adaptable as they learn and grow in new situations, form their identities, and build the skill sets needed for adulthood. For all we know about the effects of puberty on the brain, there remain many unanswered questions. What sets off the initial puberty signal in the brain? Why is the average onset of puberty shifting earlier? And, while hormones may seem powerful, they may not be the full story. Experiences you have during adolescence may be just as influential as hormones in shaping and maturing the developing brain. So while all these physical and mental changes can make you feel as if puberty is in control, you have more power than you think. The everyday choices you make, from learning new skills, to being a good friend, to setting boundaries, ultimately steer the path of who you are and will become.

🟢A carbon-free future starts with driving less The number one source of carbon emissions in the United States is coming from transportation. Globally, it's number two. And the majority of that comes from our personal use, our cars and trucks. How do we consume less energy while meeting the needs that people have of transportation? [Presented by TED Countdown and The Climate Pledge] The majority of car trips in the world today are less than five miles. It’s a simple question: Can we get more people to drive less and bike more and scooter more to where they go? The average trip on an e-bike or e-scooter produces less than seven percent carbon emissions of an equivalent car trip. Micro-mobility is dramatically more green than alternatives, and we're working every single day to reduce our own carbon emissions even further. So what sometimes happens is that a company would say, "What is the dirtiest part of our business? Let's just outsource it. And if we outsource it, we've solved our problems." But that doesn't actually solve your problem because somebody else is polluting and emitting. If we're going to live up to our own ideals then we need to do the core of what folks have always done: reduce, reuse and recycle. The early days of micro-mobility, we took a consumer scooter or a consumer e-bike and we put it into a commercial space. And what that meant was that our average scooter lasted a month. Imagine that, every month we need to buy an entire fleet for the world. And that was not green. And it created an enormous amount of shipping cost, manufacturing cost, upstream and ultimately it created problems in terms of end of life of our scooters and e-bikes. And so we found manufacturing partners that can build scooters and e-bikes that last four years, five years, rather than a month. We also then said, OK, it's not just how long it lasts, it also depends on how many of the parts we can reuse. And so we started to say, let's redesign our entire e-bikes and e-scooters so that if a scooter does break, we can take it apart and reuse many parts of that scooter. We started to use a swappable battery technology. Not only does it increase the life, it also reduces the number of trips we have to take back and forth to actually support our fleet. And we're constantly working to reduce the amount of waste that we actually send to landfill. As our batteries get to the end of life, they may not have sufficient charge to power an e-bike, but that battery can still power many, many things. We started partnering with a portable speaker maker, and we take that battery that today doesn't have enough juice to power somebody on a scooter and we turn it into the battery for the portable speaker, and it extends and it recycles into that life. A lot of these things wouldn't be part of our direct carbon emissions, but we care about it because the thing that we have to count is the true end to end life cycle of our products. When I look across all these things, it's not one thing, it's not two things, it's 100 little actions we do. And it starts with understanding and measuring our own environmental impact and challenging ourselves to do better. We have to work at building a future of transportation that is shared, affordable, but most importantly, carbon-free. #Climate_Change #Environment #Globa_Issues #Sustainability #Transportation #Countdown 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜ 🤖اموزش رایگان زبان از طریق بات تلگرام

Of course, truly open-minded listening isn’t about changing people’s minds. Good listening is not the same as agreeing, and conversations don’t have to end with a happy resolution. But even during a disagreement, sometimes being heard is enough to start a deeper conversation. #Education #Psychology #Relationships #Communication #TED_Ed #Animation 🎙Join ➣ @TEDTalksLearning ☜ 🎙Join ➣ @TEDTalksLearning ☜ 🤖اموزش رایگان زبان از طریق بات تلگرام

🟢4 things all great listeners know It's easy to tell when someone's not paying attention, but it can be surprisingly tricky to know what truly excellent listening looks like. Behavioral scientists have found that good listening is one of the most important things we can do to improve our relationships, develop our worldview, and potentially even change people's minds. So, what can we do to become better listeners? At its core, listening in a one-on-one conversation is about taking an interest in another person and making them feel understood. There’s no universally agreed upon definition of high-quality listening, but some recurring features include attentiveness, conveying understanding, and showing a positive intention towards the speaker. This doesn’t mean you can simply go through the motions— researchers have found that merely smiling and nodding at set intervals doesn’t quite work. However, there is something slightly performative about listening in that it’s important to show you’re doing it. So, in addition to actively attending to a speaker’s words, good listeners also use questions and body language that indicate their understanding and their desire to understand. This might feel awkward at first, and what’s most effective might depend on your relationship with the speaker. But with time and practice you can internalize these basic behaviors. So let’s say a good friend wants to tell you about an issue they’re having with their partner. Before even starting your conversation, remove any distractions in the environment. Turn off the TV, take off your headphones and put your phone away— far away. One study showed that even the visible presence of a phone made conversations feel less intimate and fulfilling to those involved. Once the conversation begins, one of the most important things you can do is also the most obvious— try not to interrupt. This doesn’t mean you need to stay completely silent. But if you do interject, look for natural pauses to ask open-ended questions that benefit the speaker, not just your curiosity. Questions like “What happened next?” or “How did that make you feel?” confirm that you’re following the story while also helping the speaker dive deeper into their own thoughts. Another great way to show your understanding is by summarizing what you just heard and asking if you’ve missed anything. Summaries like this show the speaker that you're truly trying to understand them rather than just waiting for your turn to talk. Speaking of which, while a good conversation requires back and forth, planning out your response while the speaker is talking is a common way to miss what’s being said. So try to stay present and if you lose focus, don't be shy about asking the speaker to repeat what you missed. This might feel embarrassing, but asking for clarification actually shows that you’re committed to understanding. Finally, don’t be afraid of silence. It’s okay to ask for a moment to formulate your response and taking a beat to think can help speakers reflect on their speech as well. These might seem like small changes, but together they make a big difference. And when people feel heard, they report more satisfaction, trust, and connection in their relationships. In the workplace, employees who feel heard generally experience less burnout, and perceive the managers who listened to them more favorably. Unfortunately, while it might be easy to listen to some people, it can be hard to muster all this focus and attention if you disagree with or dislike the speaker. But these situations might actually benefit most from your efforts to listen openly. The theory of psychological reactance suggests that trying to force someone to change their mind makes them more likely to defend their point of view. However, recent studies suggest that high-quality listening fosters open-mindedness by creating a non-judgmental and psychologically safe environment.
