How Lucid Dreaming Works
 
04:06
You may have heard of lucid dreaming, the type of dream where the dreamer is aware of dreaming. Is lucid dreaming a real phenomenon? Sleep expert Matthew Walker explains how much we know about lucid dreams so far.  Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more. Subscribe to our channel and visit us at: http://www.businessinsider.com/sai TI on Facebook: https://www.facebook.com/techinsider TI on Instagram: https://www.instagram.com/tech_insider/ TI on Twitter: https://twitter.com/techinsider -------------------------------------------------- Following is the transcript of the video: Jessica Orwig: What if we could control our dreams? When most of us dream, our thoughts and actions are involuntary. The dream plays out as if we were watching a movie. But not all dreams are the same. There is another kind of dreaming called lucid dreaming, which is more like playing a video game than watching a movie. Matthew Walker: By definition lucid dreaming is simply the act of knowing that you're dreaming whilst you're dreaming. My name is Matthew Walker. I am a professor of neuroscience and psychology at the University of California Berkeley. Most people actually think of lucid dreaming more in the sense of actually beginning to control what you're dreaming. So, you gain volitional control and you decide what's going to happen during your dream. Orwig: Frequent lucid dreamers claim that they can control many parts of the dream such as teleporting themselves to another location, learning to improve real-life skills, or even eating fire. It might sound far-fetched. And until recently we lacked the technology to prove if lucid dreaming was real or not. But a series of recent studies has shed light on the phenomenon. Walker: Scientists have designed experiments and they’ve been able to demonstrate objectively that when people say that they're doing something in that dream that they actually are. Orwig: In 2012, scientists reported results from one of the first experiments that objectively measured lucid dreams using fMRI scanners.  fMRIs measure the rate of blood flow to different areas of the brain, so they can relay information about a person's thoughts and actions simply through a series of images. For the study, scientists first asked participants to clench their fists while they were awake. This lit up key areas of the brain on the fMRI scanner. After that, participants were asked to fall asleep and dream about clenching their fists. Sure enough — similar regions of the brain lit up in both cases. Lucid dreaming comes naturally to some, but many of us have never experienced the sensation. However, that doesn’t mean it’s impossible. Walker: How can we actually become more capable of lucid dreaming? Well, it's a little bit tricky, but you can certainly try to tell yourself that you will remember that you're dreaming whilst you're dreaming before you actually fall asleep. So, try to go through a mantra chant as it were. Some people actually try to do deliberative things whilst sleeping, like turning on the lights in a room. And that helps them to become aware that they are dreaming at the moment of dreaming itself and therefore they gain lucid control. Orwig: Those who can already control their dreams with ease say lucid dreams aren’t only for entertainment but can also be used to expand one's conscious boundaries. On the other hand, lucid dreamers have also reported frightening accounts where they have trouble distinguishing reality from the dream. In some cases, this can be a sign of mental illness, and should be taken seriously. But why do some people have the ability to lucid dream but not others? And what is happening in our subconscious that triggers the experience? There’s still a lot we have to learn about the causes and effects of lucid dreaming. Walker: It seems to be only around 20 to 30% of the population are actually natural lucid dreamers. So, perhaps if it was so beneficial mother nature would have had all of us being table of lucid dreaming. And the fact that we’re not perhaps means that it's not necessarily beneficial. But we actually don’t know. Maybe those 20 to 30% of people who do lucid dream are at the forefront of hominid evolution, and they are going to be the next species of preference. We just don't know.

What Happens When You're Struck By Lightning? | The Human Body
 
03:26
Getting stuck by lightning is rough. It can burn hotter than the sun, scar your body, and even blow off your clothes. Even worse, it kills about 47 Americans per year. Although 90% of those struck survive, it's still worth knowing how to avoid getting a heavy dose of sky electricity. Following is the transcript of the video: Contrary to popular belief, lightning strikes aren’t always a death sentence. In fact, about 90 percent of people in the US who are struck actually survive. Still, victims rarely walk away unscathed, and the damage can be permanent. Lightning triggers 75,000 forest fires in the US each year and can split entire trees down the middle in a split second. So it’s frightening to imagine what it does inside a human body. The good news is that you won’t get cooked Wile E Coyote-style, but it can still do damage. For starters, lightning carries between 1 to 10 billion joules of energy — enough to power a 100-watt bulb for at least 3 months. When that amount of electricity enters your body,  it short-circuits the small electrical signals that run your heart, lungs, and nervous system. This can lead to cardiac arrest, seizures, brain injury, spinal cord damage, and even amnesia. But electricity isn’t your only problem. Lightning is blisteringly hot. In under a second, it can heat the surrounding air to temperatures 5X hotter than the sun’s surface. This causes a rapid expansion of air, which leads to a shock wave that we hear as thunder. It has been calculated that someone standing within 30 feet of a lightning strike point can experience a blast wave equivalent to a 5kg TNT bomb (Blumenthal). The intense heat, light, and electricity can also damage your eyes. In fact, it can bore holes in your retina and can cause cataracts within days or weeks. Other side-effects of lightning can include impotence in men and overall decreased libido. That’s just what happens on the inside! As the lightning moves toward the surface, it can force red blood cells out of your capillaries, into your epidermis….like a bruise. These intricate designs are called Lichtenberg figures. The intense temperatures can also heat up any metal you might be wearing, causing third-degree burns and can also rapidly vaporize the rainwater or sweat on your skin. The resulting steam explosion may blow off your clothes and shoes leaving you nearly naked! On average 47 people in the US are killed by lightning each year. So, you might be wondering, “How do I make sure I’m not that guy?” For starters, check weather forecasts ahead of time, and stay indoors during a storm. But if you’re stuck outside, avoid isolated trees, poles, and open fields, and run as fast as you can towards safety. You’re best off in a developed building or a hard-topped metal vehicle. So stay calm and just remember: “When thunder roars go indoors!” ------------------------------------------------------ #Lightning #Weather #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

How Intermittent Fasting Affects Your Body and Brain | The Human Body
 
03:17
Stars like Beyonce and Hugh Jackman have spoken out about following intermittent fasting plans to get in shape. How does intermittent fasting work? Here's what actually happens to your body and brain when you fast. Following is a transcript of the video. How long has it been since you last ate? People who fast intermittently often eat within an 8-hour block, leaving 16 hours of fasting in between. During that 16-hour stretch, their bodies undergo an important change that sets them apart from non-fasters. Here's how it works. When you eat, you store some of that energy in the liver as glycogen. But after 10-12 hours of not eating, your glycogen reserves will be extremely low. As a result, you may feel more irritable than normal, a term scientists call "hangry." The upside is — with little glycogen left — fat cells in your body release fats into your bloodstream. The fat cells head straight to your liver, where they're converted to energy for your body and brain. So, you are literally burning fat to survive. Blood samples show that people who had fasted for 12-24 hours experienced a 60% increase in energy from fat, with the biggest change occurring after 18 hours. This is the benefit to intermittent fasting because it puts you in a state called ketosis. And it's why researchers think intermittent fasting could be the key to a longer, healthier life. The process of burning fat releases chemicals called ketones. In the brain, ketones trigger the release of an important molecule called BDNF. BDNF helps build and strengthen neurons and neural connections in areas of the brain responsible for learning and memory. Which could explain why a boost in ketone production has been shown to improve memory in people with early signs of dementia in as soon as 6 weeks. Increasing ketones in the body is also a common treatment for patients with severe epilepsy. You don't necessarily have to fast to boost your ketone levels. Introducing more fatty foods into your diet and cutting back on carbs can have a similar effect. A group of people who tried this method for 3 months not only lost weight and body fat, but also saw a decrease in blood pressure and a hormone (IGF-1) that is related to aging and disease. But scientists have discovered that fasting increases ketone levels more. Ketogenic diets can increase ketones 4-fold whereas fasting has been shown to increase ketones by up to 20-fold. As a result, fasting — compared to a ketogenic diet — may have a stronger, more beneficial effect on overall health. Yet many Americans who eat three meals a day with snacks in between never reach ketosis, and therefore aren't producing enough ketones to promote good health. Fasting and ketosis have been a key to our survival from the beginning. They helped our ancient ancestors survive through bouts of starvation. And today, they're becoming recognized as a way to help keep future generations mentally and physically disease-free. ------------------------------------------------------ #IntermittentFasting #Diet #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

How Eating Spicy Food Affects Your Brain And Body | The Human Body
 
01:46
What happens to your brain and body when you eat spicy food. Hot peppers trick your brain into thinking your mouth is on fire. But there's no real heat in a pepper. So, what's going on? It's all about a chemical compound in peppers called capsaicin. Capsaicin binds to pain receptors on our nerves called TRPV1. Normally, it reacts to heat by sending warning signals to the brain. Capsaicin causes TRPV1 to send those same signals. So, you react as if there's something hot in your mouth. Your body tries to cool itself off. So, you start to sweat and your face turns red. At the same time, your eyes tear up and nose runs. This is your body's way of removing the "threat". After swallowing, the capsaicin binds to more receptors on its way down. In severe cases, you may develop blisters in the throat, vomit, and even go into anaphylactic shock. So, why do so many people enjoy spicy food? In response to the pain, your brain releases endorphins and dopamine. Combined, these chemicals create euphoria similar to "runner's high". Ultimately, your response to spicy food depends on your tolerance. So, if you're the type who cries over a jalapeño, don't sweat too much. You can build up a tolerance over time with practice. ------------------------------------------------------ #Brain #SpicyFood #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

What Happens To Your Body And Brain If You Don't Get Sleep | The Human Body
 
04:50
Sleep expert Matthew Walker breaks down the many effects of sleep deprivation on your brain and body. Following is the transcript of the video: Matthew Walker: My name is Matthew Walker, I am a professor of neuroscience and psychology at the University of California, Berkeley, and I am the author of the book "Why We Sleep." We certainly know that a lack of sleep will actually prevent your brain from being able to initially make new memories, so it's almost as though without sleep the memory inbox of the brain shuts down and you can't commit new experiences to memory. So those new incoming informational emails are just bounced, and you end up feeling as though you're amnesiac. You can't essentially make and create those new memories. We also know that a lack of sleep will lead to an increased development of a toxic protein in the brain that is called beta amyloid and that is associated with Alzheimer's disease because it is during deep sleep at night when a sewage system within the brain actually kicks in to high gear and it starts to wash away this toxic protein, beta amyloid. So if you're not getting enough sleep each and every night, more of that Alzheimer's-related protein will build up. The more protein that builds up, the greater your risk of going on to develop dementia in later life. What are the effects of sleep deprivation on the body? Well, there are many different effects. Firstly, we know that sleep deprivation affects the reproductive system. We know that men who are sleeping just five to six hours a night have a level of testosterone which is that of someone ten years their senior. So a lack of sleep will age you by almost a decade in terms of that aspect of virility and wellness. We also know that a lack of sleep impacts your immune system. So after just one night of four to five hours of sleep, there is a 70% reduction in critical anticancer-fighting immune cells called natural killer cells. And that's the reason that we know that short sleep duration predicts your risk for developing numerous forms of cancer. And that list currently includes cancer of the bowel, cancer of the prostate, as well as cancer of the breast. In fact, the link between a lack of sleep and cancer is now so strong that recently the World Health Organization decided to classify any form of nighttime shift work as a probable carcinogen. So in other words, jobs that may induce cancer because of a disruption of your sleep rate rhythms. We also know that a lack of sleep impacts your cardiovascular system because it is during deep sleep at night that you receive this most wonderful form of effectively blood pressure medication. Your heart rate drops, your blood pressure goes down. If you're not getting sufficient sleep, you're not getting that reboot of the cardiovascular system, so your blood pressure rises. You have, if you're getting six hours of sleep or less, a 200% increased risk of having a fatal heart attack or stroke in your lifetime. There is a global experiment that is performed on 1.6 billion people twice a year and it's called daylight saving time. And we know that in the spring, when we lose one hour of sleep, we see a subsequent 24% increase in heart attacks the following day. Another question, perhaps, is what is the recycle rate of a human being? How long can we actually last without sleep before we start to see declines in your brain function or even impairments within your body? And the answer seems to be about 16 hours of wakefulness. Once you get past 16 hours of being awake, that's when we start to see mental deterioration and physiological deterioration in the body. We know that after you've been awake for 19 or 20 hours, your mental capacity is so impaired that you would be as deficient as someone who was legally drunk behind the wheel of a car. So if you were to ask me what is the recycle rate of a human being, it does seem to be about 16 hours and we need about eight hours of sleep to repair the damage of wakefulness. Wakefulness essentially is low-level brain damage. ------------------------------------------------------ #Sleep #SleepDeprivation #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

3D-Printed Home Can Be Constructed For Under $4,000
 
03:13
A home like this can be built in less than 24 hours at a cost of only $4,000. The secret? 3D printing. And they could help families living in poverty and unsafe conditions. New Story, a housing charity organization, and ICON, a construction tech company, have partnered together. Their goal is to end global homelessness.  Alexandria Lafci: So having strong, sturdy walls, having a door that we can close at night — it's something that we take for granted. Being able to lock our door and be safe. For many of these families, for years, sometimes even a lifetime, they don't have that opportunity to have a safe shelter. So when they move into a New Story community, when they move into a safe home, families lives are transformed. An entire community of these 3D printed homes will be constructed in El Salvador. The ultimate goal is to get costs down to $4,000 per house with a build time of fewer than 24 hours.  This prototype house was built in Austin, TX. The home measures 650 square feet. Mortar was printed layer by layer. Human workers installed windows, doors, plumbing, and electrical systems. Here's what's inside: A living room. Small office space. One bedroom. One bathroom. ICON staff will use the home as an office to test the durability. Evan Loomis: Our first product is a 3D printer that can print a house in 24 hours for half the cost. Phase one for News Story and for ICON is a proof of concept house and the good news is we've done it. We printed the first home in the United States that's going to be permitted and for us, this is just the beginning. The real kind of home run for us is to be able to do what we've done here in Austin, Texas in the developing world and we're doing that in what we call phase two which is in El Salvador. We are going to be printing an entire village for people that don't have homes. Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

At least, in the long run. That’s right, when it comes to endurance, we can outrun wolves, cheetahs, and even horses. Now, in the beginning, humans fall short because we're lousy sprinters. Case in point, Usain Bolt couldn't outrun a cheetah in the 100-meter dash if he wanted to, and he tried. But marathons and ultramarathons are a whole other ballgame. Each year, a small town in Wales holds the Man Versus Horse Marathon. It’s a 22-mile race between riders on horseback and runners. And, while horses often win, humans will sometimes prevail. So what makes humans such endurance running superstars? The secret weapon is our sweat. We have 2-4 million sweat glands all over our body, which means we can run and cool ourselves at the same time. Having no fur is also a huge plus. In contrast, dogs rely on panting to cool down, and other animals, like horses and camels, also sweat, but less effectively. As a result, they overheat faster and must slow down sooner. The mechanics of our running stride also makes us particularly well-suited for endurance running. A human’s running gait has two main phases: Aerial when both feet are off the ground and Stance when at least one foot touches the ground. While in the air, gravity pulls us down, which generates a lot of kinetic energy. However, the second we hit the ground, we instantly decelerate, losing that kinetic energy in the process.  Here’s where our special adaptations come in. The tendons and muscles in our legs are very springy. They act like a pogo stick, converting kinetic energy from the aerial phase into elastic potential energy, which we can use later. In fact, our IT band can store 15-20 times more elastic energy than a chimpanzee’s similar body part, the fascia lata. When it comes time to step off, those springy tendons can turn 50% of that elastic pogo-stick energy back into kinetic, making it easier to propel forward. Without that extra energy, we’d have to exert that much more effort just to take a step. So, why did humans get to be such great endurance runners, anyway? Some anthropologists believe this became important around 2-3 million years ago, when we started hunting and scavenging. Because we couldn’t chase down a gazelle like a cheetah, early humans learned persistence hunting. Where they would track prey over long distances until the prey either overheated or was driven into a trap. In fact, persistence hunting remained in use until 2014, such as with the San people of the Kalahari Desert. But distance running can still help you, even if you're not interested in running down your next meal. Studies show running can lower body weight, body fat, and cholesterol levels. And the longer you train, the greater the health benefits. Just one year of training has been shown to reduce body weight by about 7 lbs, lower body fat by 2.7% and decrease resting heart rate by 2.7%. It may seem really hard, and maybe even impossible to run a mile or a marathon. But in fact, you were born to go on that run. We all were.

What Would Happen If Humans Tried To Land On Jupiter
 
04:47
The best way to explore a new world is to land on it. That's why humans have sent spacecraft to the Moon, Venus, Mars, Saturn's moon, Titan, and more. But there are a few places in the solar system we will never understand as well as we'd like. One of them is Jupiter. Jupiter is made of mostly hydrogen and helium gas. So, trying to land on it would be like trying to land on a cloud here on Earth. There's no outer crust to break your fall on Jupiter. Just an endless stretch of atmosphere. The big question, then, is: Could you fall through one end of Jupiter and out the other? It turns out, you wouldn't even make it halfway. Here’s what would happen if you tried to land on Jupiter. *It's important to note that we feature the Lunar Lander for the first half of the descent. In reality, the Lunar Lander is relatively delicate compared to, say, NASA's Orion spacecraft. Therefore, the Lunar Lander would not be used for a mission to land on any world that contains an atmosphere, including Jupiter. However, any spacecraft, no matter how robust, would not survive for long in Jupiter, so the Lunar Lander is as good of a choice as any for this hypothetical scenario. First things first, Jupiter's atmosphere has no oxygen. So make sure you bring plenty with you to breathe. The next problem is the scorching temperatures. So pack an air conditioner. Now, you're ready for a journey of epic proportions. For scale, here's how many Earths you could stack from Jupiter's center. As you enter the top of the atmosphere, you're be traveling at 110,000 mph under the pull of Jupiter's gravity. But brace yourself. You'll quickly hit the denser atmosphere below, which will hit you like a wall. It won't be enough to stop you, though. After about 3 minutes you'll reach the cloud tops 155 miles down. Here, you'll experience the full brunt of Jupiter's rotation. Jupiter is the fastest rotating planet in our solar system. One day lasts about 9.5 Earth hours. This creates powerful winds that can whip around the planet at more than 300 mph. About 75 miles below the clouds, you reach the limit of human exploration. The Galileo probe made it this far when it dove into Jupiter's atmosphere in 1995. It only lasted 58 minutes before losing contact and was eventually destroyed by the crushing pressures. Down here, the pressure is nearly 100 times what it is at Earth's surface.  And you won't be able to see anything, so you'll have to rely on instruments to explore your surroundings. By 430 miles down, the pressure is 1,150 times higher. You might survive down here if you were in a spacecraft built like the Trieste submarine — the deepest diving submarine on Earth. Any deeper and the pressure and temperature will be too great for a spacecraft to endure. However, let's say you could find a way to descend even farther. You will uncover some of Jupiter’s grandest mysteries.But, sadly, you'll have no way to tell anyone. Jupiter's deep atmosphere absorbs radio waves, so you'll be shut off from the outside world— unable to communicate. Once you've reached 2,500 miles down, the temperature is 6,100 ºF.  That's hot enough to melt tungsten, the metal with the highest melting point in the Universe. At this point, you will have been falling for at least 12 hours. And you won't even be halfway through. At 13,000 miles down, you reach Jupiter's innermost layer. Here the pressure is 2 million times stronger than at Earth's surface. And the temperature is hotter than the surface of the sun. These conditions are so extreme they change the chemistry of the hydrogen around you. Hydrogen molecules are forced so close together that their electrons break lose, forming an unusual substance called metallic hydrogen. Metallic hydrogen is highly reflective. So, if you tried using lights to see down here it would be impossible. And it's as dense as a rock. So, as you travel deeper, the buoyancy force from the metallic hydrogen counteracts gravity's downward pull.  Eventually, that buoyancy will shoot you back up until gravity pulls you back down, sort of like a yo-yo. And when those two forces equal, you'll be left free-floating in mid-Jupiter, unable to move up or down, and no way to escape! Suffice it say, trying to land on Jupiter is a bad idea. We may never see what's beneath those majestic clouds. But we can still study and admire this mysterious planet from afar.

What Losing Weight Does To Your Body And Brain | The Human Body
 
02:24
Special thanks to John Gunstad, professor with the Department of Psychological Sciences at Kent State University, for speaking with us about his cutting-edge research on how losing weight affects brain function. Following is the transcript of the video: Here’s what losing weight does to your body and brain. During the first week, you may find it easy to lose weight by simply switching to a healthier diet. But as your metabolism adjusts, you won’t burn as many calories as you used to. So losing additional weight will become harder. Making matters worse, as the fat melts away, you’ll start to experience an increase in appetite. After a meal, fat cells release a hormone called leptin into the bloodstream. This surge in leptin levels signals to your brain you’re full and should stop eating. But with less overall fat, people who lose weight show a measurable dip in leptin. Brain scans of obese patients who had lost 10% of their body weight revealed that less leptin leads to increased activity in regions of the brain that control our desire to eat. The result isn’t just an increased appetite but an even stronger urge to eat fatty, high-calorie foods, because your brain is trying to restore the body’s leptin levels to normal. However, fighting that early impulse to gorge on pizza and donuts is worth it in the long run. Besides the decreased risk of heart disease, hypertension, high cholesterol and type 2 diabetes, scientists studying overweight people discovered that losing just one pound of body weight reduces four pounds of pressure on knee joints. Losing excess weight also reduces strain on the blood vessels, increases blood flow to the brain, and boosts overall brain function. Several studies have shown that people who underwent weight-loss surgery saw an improvement in memory, concentration, and problem-solving skills in as soon as three months. Plus, brain scans indicate that people who lost weight and kept it off for nine months reacted differently when shown images of high-calorie foods than before they lost the weight. The brain regions that process reward, motivation, and taste didn’t react as strongly, whereas the areas that promote overall self-control had a boost in activity. So fighting those cravings early on might make them easier to control later. Turns out — like anything else — losing weight can get easier with practice. ------------------------------------------------------ #Weight #WeightLoss #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

What It's Like To Serve In South Korea's Mandatory Military Service
 
04:46
South Korea requires all of its male citizens to serve in the military for two years. Here's what that experience is like. Footage courtesy of Goyang TV, 2012 Following is a transcript of the video. The hardest part was when I and my group had to go into this gas-filled room. My name is Gene Kim, and I served in the South Korean military for 2 years. The law requires every male to serve the military, and it is extremely hard to get out of it. If you purposely evade the military duty, you will get jail time. The service is mandatory mainly because our relationship with North Korea. After things got intensified after the Korean War, there was a need for an active force for the South Koreans, so the military can always be ready. I served the Korea military between the years of 2009 and 2011. Before the military, I was living in New York. I decided to go because I had to get it over with it at some point. At the time I did my military service, I hated it.I just hated every moment being in there, trapped in that isolated society. And I just waited for my time to pass. I haven't seen a single person who really wanted to be there, who was enthusiastic to be there. People generally want to avoid the military because, I think, of the forcefulness of it. Compared to the US, where the military is voluntary, and you can pursue it as a career, in Korea, 2 years of service is mandatory, and everyone is forced to do it. You're living your free life and then suddenly isolated from the rest of the society. You have no contact. You can’t fill your cell-phone addiction there. And you're basically sacrificing 2 years of your youth for the nation. So, on the first day when you enter the military. As soon as you enter this training base, you meet these instructors that train you for 5 weeks on from there. They intentionally try to intimidate you, try to scare you, in order to make you into a soldier. This 5 weeks of training was one of the most intense experiences I had. You’re not even a private at this moment. You are a trainee. The training is very intense. You are yelled at constantly. You don't have a voice there. You can only do what you're told to do and nothing else. You learn to move very fast. When you’re ordered something, you have to run to get it, you have to run to do it. And if you hesitate, you get picked on for that. If you get around 5 minutes of rest, then you're happy with that. You re-learn things that you thought you already knew. There's a certain way to eat. There's a certain way to stand. There’s a certain way to talk to people. There's a certain way to do everything in the military. One of the most memorable trainings that I did was this training called "화생방 훈련." Which is to prepare soldiers to defend against a chemical attack. The hardest part was when I and my group had to go into this gas-filled room. And you enter the room with your gas mask on, and there's also an instructor there with a gas mask on. He eventually orders you to put off the gas mask. And when you're exposed to this gas it doesn't have long-term effects on you, but anywhere that's exposed would hurt like hell. It feels like a thousand needles just pinching on to you and grabbing onto you. And when you inhale this gas, it feels like you're suffocating. Basically, you can’t breathe. It's just chaos in that tiny room. Everyone’s grabbing onto each other. Everyone’s rolling on the floor. There was this one guy. He ran to the door trying to get out, but there was a guard there who prevented that. And it was total chaos. After your 5 weeks of training, you’re relocated to your battalion. So, this is your home from now on. You would stay there for your private to sergeant life. From day one to the end of your service, you hear a lot about North Korea from the officials. They designate the North Korean military as our enemy. This was the first time when I learned that North Korea has invaded South Korea even after the truce multiple times. I don't know if it's because I've been brainwashed, but now I'm convinced that they have the capability and will to do a lot of damage to the Korean Society. There's always a potential that the North Koreans can Invade us and the military's trying to prepare for that. Looking back at the experience, I think I gained a few things. There's a saying in the military, "If you can't make it work, make it work." I learned that if you really put your will and just do it, then I can really achieve...I feel like I can achieve anything.

How To Time Travel, According To A Physicist
 
02:41
Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival, explains what we know about time travel so far. Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more. Subscribe to our channel and visit us at: http://www.businessinsider.com/sai TI on Facebook: https://www.facebook.com/techinsider TI on Instagram: https://www.instagram.com/tech_insider/ TI on Twitter: https://twitter.com/techinsider -------------------------------------------------- Following is the transcript of the video: Brian Greene: I’m Brian Greene, professor of physics and mathematics at Columbia University and co-founder of the World Science Festival. It's critical that you realize that there are two types of time travel, and they are radically different. Time travel to the future? Definitely possible. We know how to do it because Einstein showed us the way over a hundred years ago. It’s surprising how few people actually really know about this in their bones. He showed that if you go out into space and travel near the speed of light, and you turn around, and you come back, your clock will be ticking off time more slowly. So, when you step off it's going to be the future on planet Earth. You will have time traveled into the future. He also showed that if you hang out near a nice strong source of gravity — a neutron star, a black hole — and you kind of get right near the edge of that object, time also for you would slow down real slow relative to everybody else. And therefore, when you come back to Earth, for instance, it'll again be far into the future. This is not controversial stuff. Any physicist who knows what they're talking about agrees with this. But the other kind of time travel — to the past is where the arguments start to happen because many of us don't think that time travel to the past is possible. The main proposal that people at least consider worthy of attention for traveling to the past does make use of a weird concept called wormholes. A wormhole is something that really … Albert Einstein again discovered. The guy has like got his name written over everything in this field. It's a bridge, if you will, from one location space to another. It's kind of a tunnel that gives you a shortcut to go from here to here. Now he discovered this in 1935 but it was subsequently realized that if you manipulate the openings of a wormhole — put one near a black hole or take one on a high-speed journey — then time of the two openings of this wormhole tunnel will not take off at the same rate, so that you will no longer just go from one location in space to another, if you go through this tunnel — through this wormhole — you'll go from one moment in time to a different moment in time. Go one way, you'll travel to the past, the other way, travel to the future. Now again, we don't know if wormholes are real. We don't know if they are real whether you'll be able to go through them. So, there are all sorts of uncertainties here. Most of us think that you're not going to actually go on a whirlwind journey through a wormhole to the past. But it's still not ruled out.

Here's how long humans could survive in space without a spacesuit
 
01:32
Why are astronauts always wearing those bulky suits? You don't NEED them, do you? Here's what would really happen to an exposed human in the void of space. Below is a transcript of the video: What would happen if you went to space without a spacesuit? Whatever you do, don't hold your breath!The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. Oxygen in the rest of your body will also expand. You'll balloon up to twice your normal size, but you won’t explode. Your skin is elastic enough to hold you together. Any exposed liquid on your body will begin to vaporize. So the surfaces of your tongue and eyes will boil. Without air in your lungs, blood will stop sending oxygen to your brain. You'll pass out after about 15 seconds. 90 seconds after exposure, you'll die from asphyxiation. It’s also very cold in space. You'll eventually freeze solid. Depending on where you are in space, this will take 12-26 hours, but if you're close to a star, you'll be burnt to a crisp instead. Either way, your body will remain that way for a long time. Gut bacteria will start to eat you from the inside out, but not for long, so you will decompose very slowly. You could be floating in space, unchanged, for millions of years. Who knows, maybe an advanced alien race will discover you!

Here’s How Much Damage A Stun Gun Does To Your Brain And Body | The Human Body
 
01:32
*Editor’s note: the statements from 0:13 to 0:20 are incorrect. The shock from a stun gun is more similar to that of an electric fence. We apologize and regret the error.* The effects that stun guns cause to your body are — literally — shocking. Following is a transcript of the video. Stun guns don't just affect your body. Your brain also takes a hit. Stun guns shock you with 50,000 volts of electricity. That's 5X stronger than the maximum voltage allowed for electric fences. When that much electricity enters your body... ... it hijacks your nervous system. Normally, nerve cells use electricity to send information from the brain to your body... and vice versa. If you stub your toe, for example, neurons fire electric signals to your brain which interprets them as pain. But the human body generates at most 100 millivolts. When you're shocked with 500,000X that amount... ... it's like a power surge to your nerves. The shock overwhelms your nervous system, causing your muscles to lock up. As a result, you can't move and will likely fall down. But mobility isn't the only thing you lose. Your brain's ability to process new information is also impaired. Plus, you have a harder time remembering that new information later. Don't worry, the damage is only temporary. Brain function returns to normal after about 1 hour. Luckily, your body bounces back much faster. ------------------------------------------------------ #StunGun #Brain #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.

Here's What Happens In Your Body When You Swallow Gum | The Human Body
 
04:08
We have all heard of terrible things that take place inside our stomach when we swallow gum. But is it really that big of a deal if you forget to spit it out? You may have heard from your 2nd grade teacher that if you swallow your gum, it could stay in your stomach forever. Or worse, it could grow into a rubber tree. Well, that's true. Don't do it. Just kidding. Swallowing chewing gum isn't really going to plant trees in your stomach, but that's no reason to start doing it regularly. Here's what happens to your body when you swallow gum. When you eat standard food, three processes go to work in your body to turn food into fuel. The first is obvious: Chewing. The process breaks food into smaller and smaller pieces, increasing the surface area. Meanwhile, saliva coats those pieces, delivering enzymes that help break down the food. Finally, once swallowed, the stomach acids turn any remaining food pieces into mush. This lets the food pass through the rest of the digestive tract smoothly. But gum doesn't play by those rules. As much as you chew it, gum doesn't break up into smaller pieces. Because it's gum. Duh. Gum has been around for much longer than you'd think. Ancient Mayans and Aztecs harvested resin from the Sapodilla tree. They would dry it into a 'cha', and chewed it to stave off hunger. Even back then, it was also recognized as a breath freshener. However, most gum today is made from natural or synthetic polymers, most commonly butyl rubber. It’s used in all kinds of products, including adhesives, fiber optics, sealants, cling film, paper, fuel, explosives, sporting equipment, roofing, bottle stoppers, and tires. But don't worry, the butyl in gum won't make you sick. Because it can't be broken down, the wad of chewed gum hits your stomach intact.   Your saliva enzymes and your stomach acid can't touch the butyl in the gum base. But that doesn't mean it just hangs out. Your body is equipped to handle gum in the same way it deals with other food it can't fully digest, like corn and sunflower seeds. The muscles of your digestive tract move it along and eventually flush it out of your system in a day or two, along with everything else. So, no, your gum doesn't stay in your body when you swallow it. But that's no reason to start gulping it down by the pack. The more gum that your body has to process, the higher the likelihood that it'll build up. This gum mass could potentially clog your digestive tract, causing an intestinal blockage which can trigger stomach pain or constipation. There's a lovely name for this blockage: a bezoar. An 18-year old Israeli woman once suffered from a bezoar that blocked her stomach. The problem? Turns out, she had been swallowing at least five pieces of gum every day. The blockage had grown so large that doctors had to break it into smaller pieces and then fish it out of her, piece by piece. But chewing gum alone isn't necessarily bad for you. A couple small studies have shown that the act of chewing gum can actually help relax you. Because it can help reduce levels of cortisol — a common stress hormone — in your saliva. So, feel free to unwrap a stick.You won't be alone. 56% of American chew gum, each about 280 sticks per year. It's a 2 billion dollar industry in the U.S. But be wary of swallowing it once done. The occasional piece of gum won’t hurt, but with everything your body already does for you, why put it through the extra work? Just don't spit it out on the ground. That's just gross. ------------------------------------------------------ #Gum #SwallowGum #TechInsider Tech Insider tells you all you need to know about tech: gadgets, how-to's, gaming, science, digital culture, and more.
