Lucid dreams are both amazing and a little weird we feel awake and away or even though your sleeping Research Suggests you can even influence the course of a lucid dream and then choose to say fly like a bird. Or be a star performing on stage you can make it happen in your dreams before we examine the latest research lets take a look at what some of you our viewers have to say. On facebook we asked. Whether you can remember your dream of so what the best one was about. Jonathan responded i once went into a house and wanted to write my name on the wall that i looked in the mirror and knew it was only going to rain. He says he goes travelling in his dreams wherever he likes its only a. Monsters snakes or dogs that he realizes hes dreaming. Another viewer recently wandered among the pyramids in egypt while lying in his bag. When leo is stressed about work he dreams about it but eventually realizes its just a dream he says hes smarter when hes asleep and always comes up with a solution if he wakes up he writes it down and goes to sleep. So what do researchers say about lucid dreaming. The laws of nature dont apply either. You can experience bizarre situations. Normally youre not aware that you dreaming but if you are youre experiencing whats known as a lucid dream. Statistics suggest around half of us have experienced this phenomenon where its actually possible to control the course youre dreaming takes. Most interest is a neuroscientist at Heart UniversityMedical Center in the netherlands hes been pursuing research into lucid dreaming. Its interesting in itself is an unusual phenomenon but its even more interesting within the context of the function played by dreaming in general sized what we want to know is does dreaming possibly have a biological function and if so to what extent does it have a neuro biological basis and can lucid dreams teachers things about the function of dreams and sleep in general is a mark of mine. What happens in the brain during a lucid dream thats what martin tesla wants to find out hes even had a test candidate sleep in an m. R. I. Scanner or while connected to him like here. The brain waves he records reveal which parts of the subjects brain are active. Lucid dream is able to apply logic to whats happening unlike people dreaming the conventional way we can see that reflected in the brains activity especially in the frontal area behind the forehead there we see a lot more activity so the person were awake and in a lucid dream you can even practice things. Scientists in the german city of heidelberg test candidates to throw coins into a cup initially while awake then one group practiced the same exercise dreaming the next morning their accuracy had improved noticeably. People who often have nightmares appear more likely to have lucid dreams one study in vienna looking at possible therapy. Found that seventy five percent of its test candidates had learned how to have lucid dreams. That might be because people who regularly have nightmares are usually able to recall that a key factor in learning how to induce lucid dreaming. It can also be useful as a therapy because those who can learn to control their nightmares no longer need to fear them. The researchers in the netherlands are using modern technology to look for new methods for learning how to. Win a common strategy is to ask yourself several times a day are my awake or dreaming especially when you find yourself in an unusual or dreamlike situations eventually youll ask yourself this in your dream awake right now or is this a dream. Dreams often incorporate bizarre or illogical elements. If you stare at something in a dream it eventually starts to blur. So if you consciously stare at your hand several times a day eventually youll start doing it in your dreams to me then your hand will change a clear sign that youre dreaming. Martin tesla is now helping others to learn how to use lucid dreaming with the help of Virtual Reality the special glasses make computer simulations look remarkably real. Like a tom train like situations dont usually occur in our daily lives but Virtual Reality allows us to simply create them so our test subjects here are doing ordinary tasks and then suddenly strange things occur and then they ask themselves are my awake or am i dreaming. Its candid it is currently experiencing a simulated dream shes meant to be sorting out follow this. Every time the situation grows strange she asked herself whether shes awake or treating. The test candidates spend forty five minutes in the Virtual Reality that three times a week. By are still in the process of collecting data but it looks like the Virtual Reality training works a little better than conventional training twenty. Lucid dreaming is still something of a nice topic and few serious scientific studies have been carried out in the field to date. Much interest is looking to change that he sees many potential applications for his we set. This because its still very speculative at the moment but one potential areas schizophrenia patients suffering from schizophrenia often have the problem that they dont realize what mental state theyre in and its possible that lucid dreaming could teach them how to do that and then there are a limited states of consciousness where people might be unconscious and unable to communicate normally here research into lucid dreaming could certainly be helpful in establishing and transferring this kind of communication across various states of consciousness. Need training method from the netherlands could help more people gain control of their dreaming their for therapeutic purposes all simply to enjoy having the power to actively shape. What if furious soccer fans popped up in your dreams scaring the referee gets it wrong a player is fouled tens of thousands are wrapped in yells screams and jean years for an outsider mass displays of anger can be pretty disconcerting but there are reasons for the emotion anger serves the purpose. Of why do people get angry rage have a purpose. Psychiatry kastner specializes in anger. Anger sense feedback it indicates that someone has crossed a line with me and we need to hold on to the same motion and use it for it has a function its been a basic emotion throughout thousands of years of Human Evolution provides us with insights into ourselves as see from. Anger is a primal feeling that can help you understand yourself better its also a way of fighting back its a stop sign and it affects the entire body when you get angry youre a mic till it goes into action it releases stress hormones. Your Blood Pressure rises along with your pulse rate you begin breathing faster and muscles tense up. Your face can become flushed and go red your body prepares for a fight. Its a feeling that manaf. Early in human development. I gets a few areas. I get louder and louder and then i screen it. Now i get annoyed and then i get sad and. Anger is an unpleasant sensation and rage has a Bad Reputation anyone who grows louder or begins shouting is viewed as out of control however Heidi Kastner warns you shouldnt try to stifle your anger trees written a book about the emotion and encourages people to stand by their rage. When the many images only if i dont express my emotions that i cant give other people feedback about my mood and im not communicating properly. To others then wont understand how i feel. Expressing how angry we are our facial expressions often give it away when people get angry they grimace in voluntarily they often need their brows buggin to glower and lift their chin ups. The message is clear im spoiling for a fight. But communicating anger to another person requires direct eye contact if an angry person keeps glancing away from us we recognize the anger but dont take it personally. So if you want to communicate anger to someone you should look directly at them and then rage expression also makes you look more physically imposing. Its nearly impossible to hide visual clues that youre angry but the emotion also has positive aspects how can you make use of your anger in the. Fronting it by recognizing it and by using it for what its supposed to be which is an engine of change its an engine for self reflection for authentic interaction and when necessary for changing circumstances. Anger an engine for positive change and a source of in a power. I we also asked you on facebook what makes you angry and how do you show what. Bush here says what makes him mad is not being taken seriously. When try and gets angry he calls people on the telephone. And scolding the reports that she just weeps. All timers as a kind of dementia the brain stops working properly nerve cells die to abnormal structures appear to be involved plaques and tangles plaques or deposits of better amyloid a protein fragment that builds up in the spaces between nerve cells and disturbs their communication. And healthy neurons towle proteins help stabilize an internal structure called a micro to kill a transport path for nutrients and molecules. In all timers tell mama kulas detach from the microtubules they stick together and form thread and then tangles inside the neurons and eventually destroy them. In the battle against better amyloid plaques researchers have identified a possible ally. Christine hans from the jim incentive for nero to generative diseases is a biochemist hes been researching all scientists for decades one focus of his what is the role of amyloid protein aggregates and how they develop into plaques in the brain. As a feeder forces like it was a thought in my many studies indicate that were all as extremely high risk of developing alzheimers. The time the risk rises dramatically with age. The tomato that me answer since society as a whole is aging we have to reckon with rising numbers of patients and thats exactly what were seeing little. So what if the brain could be cleared of plaque before it damages and kills nerve cells. There are special immune cells in the brain called micro gear that hunt down and destroy whatever does not belong there and could do it hum. Bacteria for example or damaged or dead neurons. Find something out of kilter they respond immediately. Their activated migrate towards the offender and devour it. For the most part microbe liers cells provide the brain with excellent protection but do they also consume and destroy plaques. Christiane hearts and samir a paris car set out to answer that question. They have noted that certain patients ones with defective micro clear cells develop a particularly aggressive form of alzheimers at an early age. Is there a connection. At the center for neuropathology at looked like Maximillian University in munich paris car heads to a diagnostic lab to collect samples of brain tissue from two patients. The first comes from a patient who was still in the early stages of the disease when the microbe leo was still active. But were they destroying plaques. The second sample comes from a patient who had the aggressive form of alzheimers. Here the microbe leo were defective. The researchers suspect the patients defective immune cells had not been devouring plights. Samir apparent scar stains the samples the micro clear and plaques show up in different colors. So what do you do when theyve been activated. The plaques are red. Brown many of them are right on top of the plaques. As you can see there are lots of. Folks especially the bigger fox but also the smaller ones so my quickly i do consume plaques to rid the brain of them at least at first. Its been shown that healthy likely attack plaques five years before any symptoms of alzheimers are noted in a patient with defective mike oakley a cells its a different story on the left the sample with normal my currently a cells they attack the plaques on the right the sample with defective might have clia hardly any of them attack the plaques. Making clear from i quickly a look like theyre dying because there are a few of them here and throughout the brain not just around the plaques than in a standard case about timers. This result is the basis for the teens further research. And a nickel clearly wanted to activate micro glia and devise a trick that makes the march over to the plaques and start to devour them we would also of course want to do that in alzheimers patients who dont have defective micro clear but normal ones and it could perhaps help those patients to by boosting their response so. That my kitty a must not remain active all the time because that damages them so hass and his team need to get the mean cells to rest when necessary and only attack at the right time in the right place. Resurgence of all timers and other forms of dementia is a matter of some urgency for the sake of each patient but also because the number of patients who suffer so world worldwide as populations grow and grow older. The problem is right why are there but only a few. Do you have a science question that youve always wanted answered were happy to help out you send it to us as a video text ovoid smell if we answer it on the show or send you a little surprise as a thank you can i just ask. Todays question is from monica drove her in canada how does the mean influence weather here on earth. Mushroom hunters claim that after a moonlit night youre more likely to find extra healthy specimens ones that are largely free of worms. Conventional wisdom says thats because clear nights with a full moon are cooler than others which is generally true but its not the moon thats responsible for the lower temperatures its the lack of clowns that would have helped retain the heat absorbed by the planet during the day. When the sky is clear skates more easily from the lower atmosphere leaving it colder on the ground. But the moon does have an effect on weather albeit indirectly its the moons gravitational pull that causes time and there have been flow moves large quantities of water which acts as a heat buffer and therefore influences weather patterns and its estimated that without the tides our planet would rotate three times faster that would have drastic results turbulence in the atmosphere would increase enormously creating hurricanes with winds up to five hundred kilometers an hour and huge destructive power. Temperatures in the summertime would be as high as sixty degrees celsius in winters the thermometer would plummet to minus fifty. And the moon not only breaks the earths rotation it also stabilizes its orbital axis ensuring a relatively constant tilt with respect to the sun and stable long term weather patterns on our blue planet thats why theres little seasonal variation of the equator the sun is strong there all year long and there are regular showers making the tropics a paradise for many living organisms. The. Its poles by contrast up places of long dark winters with temperatures hostile its a life. So without our moon the earth would start to wobble and that would not only affect local weather all over the planet but climate on a global scale as well that wouldnt only pose a threat to plant life but all life on earth. So what a good thing we have it our moon. To leave a comment or ask a question just drop us a line on social media. Hundreds of thousands of asteroids and comets are zipping through space there are trajectories can be hard to compute sometimes they bump into each other and the collision can cause them to move in unexpected directions tiny celestial objects are always heading our way but sometimes a big one goes too and thats a dangerous situation. There a danger lurking in space asteroids are chunks of rock that orbit the sun at incredible speed and if a big one strikes the earth the result is disaster. Scientists say thats exactly what happened millions of years ago it disrupted the Global Climate and helped kill off the dinosaurs. If another asteroid were headed our way what could we do need shield aims to create a line of defense its head alan harris says the first step is to identify the threat to visit those urges interview we know where they are or how did we can say with certainty that for the next couple of hundred years nothing very big is going to head towards us either the smaller objects are much more common for we can expect to see one thats about twenty meters in diameter. Every hundred years or so. In february twenty third teen a small asteroid about seventeen meters across exploded above the russian city of chelyabinsk the shockwave damaged buildings and blew out windows hundreds of people were injured most by broken glass it came out of the blue with a bright flash and allowed sonic boom. A network of telescopes monitors the skies at all times its hard to pick out some of the smaller objects even so astronomers discover on average four new asteroids every day Twelve Thousand objects are thought to be potentially catastrophic and so scientists are working on ways to prevent them from hitting earth. The first is to deploy gravity tracked is a spacecraft hovers near an asteroid im alive on the gravitational attraction between them to slightly change the asteroids course away from earth the more massive the spacecraft the more effective it is. Now i met a very precise method of what we know where the asteroid is since the gravitational attraction between asteroid and spacecraft is very weak it can only shift its course by a very tiny amount so wed need a lot of advanced warning to change its direction enough ten or twenty years to shatter. Plan b. Would apply if there isnt enough time for that this mitigation method deploys kinetic impactors. A projectile slams into the asteroid at very high speed the European Space agency and nasa are planning a first test next year two spacecraft will be sent to the asteroid did a mass and its tiny moon the moon one craft will observe and send a lander to take samples from. The other will be sent crashing into did he mean. It. Like a game of cosmic billiards. Neo shield scientists are trying to model how much did he noone will change course as a result. The ends tomorrow in situation freiburg germany is simulating taking aim at asteroids with a space gun this incredibly fast accelerator is used to fire tiny alabamian projectiles at different kinds of rock at speeds approaching ten kilometers a second. The force of impact is nearly doubled as material from the asteroid surface flies in the opposite direction its called momentum announcement these and file transfer have here momentum transfer through the impact of the projectile and also through the material thats expelled and moving in the opposite direction to the impact. From the net effect is to enhance the Forward Momentum as in a jet engine with mass propelled to the rear and forward acceleration to this landing on the field but thats only really effective against smaller asteroids that are dense and solid and not crumbly and poor as rock piles. Then theres the third method blast deflectors. Also sort of a very big object were heading here and we only noticed rather late wed have to resort to our last line of defense and detonate a nuclear device. In the worst case that could have a scatter shot effect breaking up the body into smaller pieces which would rain down on earth and could have very serious consequences thats counter to say schliemann forgan field. But with no immediate dangers in sight neo shield has time to build up earths cosmic defenses.
