d, w dot com. ah, ah ah, ah, welcome to global 3000. profiting from poverty. how slumlord in nairobi exploit those most in need. policy pays off how indigenous people in mexico, a using top quality coffee to fend off the competition and atomic power. no, thanks. why germany is turning its back on nuclear energy. chernobyl and fukushima. the west to nuclear disasters in history. radioactive waste can remain hazardous for thousands of years. yet many countries say nuclear power as climate friendly, because the nuclear fission reaction doesn't to med c o 2. there are currently 443 reactors in operation worldwide. most in the u. s. followed by france, china, russia, japan, south korea and india. and there are plans to build more according to the international atomic energy agency. global nuclear production is set to double by 2050. germany however, aims to shut down its atomic energy plants by the end of 2022 including blocked off which is the country's most controversial nuclear power station. 7 these protestors are making their voices heard and have been doing so for decades outside a nuclear power plant in northern germany. 6 for over 35 years now, activists have been meeting up once a month to call for the reactor to be shut down to day is the 425th and final time that they'll be here braving the elements. that's because the blocked off nuclear power plant, one of the most controversial in germany will be decommissioned at the end of the year for pastor and protest co founder hans, good havana. it's a day of mixed feelings. it's been florida's is up. i'm glad it's being taken out of operation. so i'm but i'm also a bit nostalgic in a v because i know i won't be seeing the group again any time soon. so but it is mainly a sense of relief that the nuclear power plant is finally history. we never imagined back then that we'd have to hold out so long on the used in risk. it all began in the 19 seventy's and eighty's, west german students joined forces with other largely left wing groups to form an anti nuclear movement. then in april, 1986, an explosion and the chair noble nuclear power plant caused a reactor meltdown. the entire region was contaminated and to this state remains uninhabitable. west germany was one of many countries to register a serge and radioactivity. the punk doff reactor was the 1st in the world to go online after the chernobyl disaster. 6 months later, several 100000 people turned out in some clash with the police consequent, havana and his fellow campaigners were determined to protest peacefully and to continue until booked off was closed down. gondola in an sean cha, i have distinct memories of chernobyl. if yet my kids were still small and weren't allowed to play outside in the sandbox. there was widespread panic on this. what is the fall out involved and what are the effects evict us? we were quite scared of cisco dies is that to this? oh, but what helped against that fear was taking a stance in doing something good by protesting what is to you don't go, rosalind on me look. and they were light to be wary of radiation. a study conducted in 2008 indicated that children growing up near german nuclear reactors including bach, dora, or it's significantly higher risk of contracting leukemia. tax revenue from the local power plant enabled the village of walked off to expand and invest in a swimming pool and other facilities. but now a financial fallout looms. dom murphy, easton dot to law we as a local authority will always support our commercial enterprises. tivo understood your head, can i? we could have kept a few nuclear power plants running a bit longer until the right structures are in place for renewable energy on all foodie annoy. yup. i'm in again or else, right. and could shuffle the 2011 fukushima nuclear disaster prompted germany to declare a nuclear phase out by the end of 2022. but many countries continue to rely on nuclear power. they getting in the levy. this promotional film made by the french nuclear industry depict set as clean and above all climate friendly. a line of argument also favored by that countries president and i said, you know, yet donal no. so to achieve our objectives, in particular carbon neutrality by 2050. we will, for the 1st time in decades we launched the construction of nuclear reactors in our country of nuclear llc or b. greenhouse gas emissions are lower than those from fossil fuels, but compared to wind or solar power, nuclear energy production is far more expensive. it's really clear those countries around the world that are most intensely committed to civil nuclear power. ah, either countries with nuclear weapons or countries really demonstrably keen on nuclear weapons. the use of nuclear energy for civilian purposes also forms the bed brought in a number of cases for nuclear weapons programs. the point that paris and washington make no bones about if you do not have a civil nuclear industry, the engine is the special metals. the welders, you can't build a nuclear proposed submarine. so these countries are looking at it and their reports in the u. s. that are absolutely explicit. even if nuclear power were twice as expensive, we would still be rational to build it. it because it helps us keep this military commitment. the blocked off protesters take pride in their activism. the reenter will be shut down, but the radioactive waste will remain in storage there for decades to come. there's still no permanent disposal site anywhere in the world, which is why the activists plan to continue their fight. but for now, they can at least claim a victory after a 35 year long campaign. clean and sustainable environmentally sound. most business sectors of focusing more and more on these requirements agriculture to needs to become more sustainable, depleted soils and widespread deforestation. mean farmers need ever more fertilizers and pesticides to grow crops. research suggests that small scale farms tend to be more sustainable and more resilient, but this tough competition from agribusiness is in mexico. some coffee produces a pouring their energies into quality. are reported katya. dana found out more it's early morning in the wave of progress. so a village in the mountains of vera cruz this way, the altar, who are tis echo family, live their napa and at home they speak not wattle. no one in black below are no lake near at m. listening to what i just said means greetings to the german viewers. oh, mexico is home to some 2000000 now. wow. which makes them the largest indigenous group in the country. now wattle is one of over 60 indigenous languages spoken in mexico, which along with spanish are recognized as national languages that families laughing about. a recent incident, a bittersweet story with me said one, the 3rd, if you so cleverly, lawanda, my sister had overslept and was late. and my father mentioned that he'd seen a commercial on tv for some radio device that cost 5000 pesos. you got both of them said went to the comparison and i said, you can't even afford to put food on the table and you want to buy an expensive radio device yet. is confirmed on the number with the altar was grow coffee. every member of the family owns about a hector of land, so they have coffee plantation spans about 5 hector's. they've been growing coffee for generations, but coffee production has never been a reliable livelihood. the family has now joined up with an organization called cafe color, hoping it will help them earn a secure income and finally lead a more comfortable life. which of the law from india and most of the pros, co, many families that work in coffee production live in poverty. it's unacceptable that they have to live in these conditions. when coffee is such a valuable commodity go, just because there are certain aspects of the production process, they aren't familiar with this of surplus, but certainly the order. the 1st step is to grow greater quality coffee, being a school of the coffee co buys the families, harvest at a higher price than the going market rate and then sells it on the coffee. farmers are given advice in the fields and their beans are analyzed to see how they can be appraised eye in the coffee called headquarters. and shall apa the capital of the state of their crews. the beans are examined and sampled in the laboratory. so was it with yellow? there were socialists and quality control. at this point, we're examining the actual appearance of the beam. the point of our analysis is partly to give the farmers feedback so they can optimize the production process orders with it. if there is no will occur, as you can see here, we found coffee bore beatles a type of past that has infested the cropped on one of those. so we have to do something about that. a coolness with them is we need to tell the farmers that they have on the problem blevins. so it's very important for them to keep their fingers clean in order to get rid of this past. but i gave them was just a deposit of the coffee beans that aren't infested or then processed for sampling, roasted wade and ground. the experts gather for a 1st round of aroma testing. initially, they keep their opinions to themselves. one, clinical zachary, of anything you say might influence the others, the law. so no one speaks while we're sampling and does he no, not over those or no. mr. at this stage, identifying the best tasting beans, isn't the main priority. mendoza? las hamilton in the health and safety aspect is important. good must hold a coffee beam. it's been roasted too long, isn't healthy. i mean, we'll do in poker on golf. we also need to identify if any contamination occurred during the processing was over for over fermentation for war. fungus infestation to municipal duncan. so victo, the experts also share their findings with the coffee produces the goal is to improve the production process so that ultimately the product can fetch a higher price. kathy cole has also set up a fun to help families, such as they're all take was they paid in advance on their harvests, which means they no longer under pressure to sell their coffee to the 1st distributor. they can find the fund is backed by, by of been a project launched by the international climate initiative in mexico. most coffee has grown not in monro cultures, but in traditional shaded coffee plantations, which benefit the environment. the alter for our family, had almost given up on the coffee cultivation was good, but with the support of kathy cole, they're more hopeful now that it can provide them with a secure livelihood. come your me mentally, that my perspective has changed. that our home was her lace. it were the m. i used to think they are what will be will be is no you though boston. i didn't know anything about the quality of my coffee beans. cafe. he thought. so this is a success. and we're going to continue growing our column pocketbook. so far, kathy cole is working with 180 producers, but hopes to increase that to 600. the project will help secure the coffee farm as the steady income and ensure that the local climate friendly plantations can thrive . o v t is on the rise across the globe, thanks. in part to the many crises facing us, including the pandemic, poorer districts, are expanding in cities, take the slums of nairobi, for example. more and more people are moving that out of financial desperation. oh, because drought has devastated their villages. many slumlord see it as a business opportunity. they rent out substandard housing to tenants who are already in dire straits. my tare is one of kenya's biggest slums. landlords such as peter chica, offer the cheapest possible housing with no kitchen or running water and collect rent with violence if need be. they taken a lot of money and have the reputation for exploiting kenya's poorest got on. well, i've got 30 houses here and matter that i've been building them since i came here and i want to expand. my big goal is to have 40 houses. it's good to be a landlord when you're getting money from all these households. you can make a lot and expand faster than the income let's you build a lot of new houses, the dell id or your business. but the housing market is not regulated here. tenants have to pay whatever the landlord demands. people share living space to make it affordable. an average $2.00 people live in a one room shack which costs the equivalent of $30.00 euros a month. peter check a usually collects the rent himself on camera. he makes an effort to be friendly. m . hi, how are you? you got something for me, carla. sure, i'll fetch it. okay. okay. it does allow, does your husband home walker? no, he's not there. no problem. and when he gets in this, tell them hello from me. we'll go. when tenants don't pay the rent on time, the slum lords higher gangs to collected gangs who can be quick to resort to violence for about $10.00 euros. they'll strong arm the tenants or throw them out of my chair. and some night when i did was up in maryville, who is one of our landra crushing a bit of summer incentive lives. i'm was the tenant was me enough. i myself. i've written some people out. looks is. yeah you, you have to be done so than to who graduated so to have that gosh, you must be tough so that to the boys and see that you're doing a good job in the largest son, bolivia, they had been tougher you out of there will you become. 6 6 agnes lavetia has been living here in montana for 18 years now. hold quote, on other causes, i came to the slum of my tare, so my children could go to school. or there's no work for me right now. i used to get by and dan labor to pay the school fees. oh my god, the corona, my rous, made things a lot harder. there are no jobs any more at 10 o'clock. i don't have money for food or rent. everything's become much harder because there hardly any chance is left to earn money in a book which i sometimes i'm so stressed i get sick one good her plight is a common one here. life in the city can quickly become a trap. the informal economy as a strangle hold on the slum food, water, electricity, and rance all cost. more than in the countryside. peter che, keeps meticulous records. those who pay get a receipt. those who don't can expect a visit from a street gang hilliard administering flu. another letter, the young gangs know the locals here even better than the police said when you had to be in a yard work to do a go and are always willing to collect the rent lynette echocardiogram. if you go to the police, they'll ask you for a pile of money. first of your present means you end up paying more than 6000 shillings. the tenant owes you the redundant now or 40 or they did over the average if they're magnus, new heavy. she lives with her husband, children, and grandchildren. 8 people in a one room shack with no kitchen, bathroom or running water. if they can't pay the back rent soon, they could be out on the street. since the pandemic hid, a lot of people here can no longer pay their rent. so many of peter take his houses are standing empty. come, my dear, i haven't been able to contact the tenant of this place for 3 months in this apartment. the tenant has been out of work for 3 months so far. i can't get anything from him yet. allow this rent or moved out after not paying for 6 months because of the corona pandemic. lego, the place has been empty since then. and enters. enters peter che got might be complaining, but he's doing very well compared to his tenants who face extreme hardship. he's a man of 2 faces. he might leave the tenants alone for a few months, but then he'll send a gang around to settle, matters by force. meanwhile, the residence of maternity remain at the mercy of him and his fellow slum lords. escaping poverty can seem almost impossible. one way is through a good education and that doesn't necessarily mean a business or medical degree. deafness and imagination, for example, can be very useful. and then very much in demand in one rather magical place on the outskirts of cape town. ah, and to vote, love counselor, call it back in. the school, opened its doors every saturday with a bit of juggling a bit of balloon swallowing. and all the classic magician tanks by teaches in a timber which he 1st came here as a student himself, 16 years ago. it teach me a lot of things that goes dodge best would have to start discipline to love myself or to, to, to respect other people ah, to work hard in life and to be honest as well. that's what he thought me magic. so from here, yep. and her hand yellow go up, is gone, and then suddenly opened a hand slowly and then you put your hand behind on them. and then you roll the ball, roll the ball. so from the side underneath here, the roll, the ball i among got you 40 is one of approximately 200 students at the college of magic in cape town, or they once a week training and take 6 years. all the, many of them go on to work in theaters or as performers, the children's birthday parties and corporate events. legit it's mind blowing. that's why i love doing magic. i love to see proposed amazed by me. like i, a banga to footy, most of the students come from the townships where poverty has been further exacerbated by the pandemic. he's an ambitious young man. he wants to be an engineer. magic is mainly a hobby, but it also teaches him useful life lessons. when it comes to minutes, you have to practice every day. also in if you need to be good. also magic if you want to be good, you have to try again. try again that i had meeting the same team. then you'll find yourself good enough. his family probably won't be able to afford to pay for him to study engineering. he'll be graduating from the college of magic in a year and hopes he'll then start to make some money himself. oh, i met you can de turned on. now, course i can do that. he can do magic i in cleanable biopsies didn't that you can help us have a better life, some dental plan, no tindy cool big. and i no longer has told me that hell guy, us, what we mean when he starts to perform and get paid. the rest of us are unemployed, has the pun, gailey, we are going with the young the titian practices every day. he doesn't have juggling balls, so he uses potatoes instead. his teachers in a timber wood, he comes from google later, another township. he says that magic helped him stay on the straight and narrow in these neighborhoods. it's all too easy to be led astray to see god that you are growing up doing to drugs and then they're doing bad stuff and in a feel bad, you know. and then you look at them and, and what affect your life? is it. thank god, you know, i'm still here today and then you look to some people to say, no, no, no, no, no, i don't wanna be like, you know. so that's why we people like me was kept really is what i was getting this by younger kids. so i don't for, for the same about the people for he performs at corporate events and for children in hospitals. but wherever he is, he always has a trick of his sleeve, almost double in. well, this is 10 rather they've been holding boardington and polls the began. when i'm done holding it will turn into 100. ready? oh oh. oh oh, his audience. awesome. can't believe their eyes a, it really is 100 ran a students from all sorts of social backgrounds take part in the 6 year training at the college of magic. it costs the equivalent of $350.00 euros. the year. sponsorships and grants are available to students who can't afford the fees. everybody hands up in the sky with offering us on the calendar for you. don't forget to set a magic word. oh, come, oh, oh, no holy i. now not all the students will go on to make a living as magicians, but still they will have learned many valuable lessons here. i feel juggling and, and drop the ball it's you must been and pick up the board is a lesson a teaches you as well. ah, once once you're for the life, you have to pick up a soft and, and continue because this is a still a long journey. and also if you're not just give up, so that's all listen ah, that's old from us at global 3000 this week. do you drop us a line with your feedback? you can reach us at global 3000 at d, w dot com and we are on facebook to d w global ideas. see you next time until then. take care. ah ah, with with so close to the stars, a james web space telescope is supposed to bring distant galaxies within reach out with today's new super lenses. not even black holes are safe. tomorrow to day. next on d, w, and dr. turn 70 in town d w. what's truly important in life with we take a look at his and future. meet the artist, a very personal, ken, legato, arch, 2016 in d. w. o. devastated with cars carried life money. the fact of climate change, i mean failed to plug wired before a station in the rain forest continued carbon dioxide emissions have risen again. young people all over the world are committed to climate protection to willy. because change doesn't happen on its own. make up your own mind d. w, made for mines. how can drones both cheap and versatile at valence research. also on the show we had to japan where new and old technologies are being used to make stunning replications of art. but we begin with a close up look at the james web space telescope. scientists have great hopes for it to discover the lug. ah, welcome to to morrow to day. the sun shone on d, w. 321, and what dog to play, so will discover with robins place. oh, good window on the universe. just over 30 years ago, travel space telescope was launched into orbit. it's been sending back stunning images from the depth of space ever since. thousands of publications have been written based on his observations, but with advancing age they comes advancing new technology and thus hubble is due to be replaced by the james web space telescope. soon after the launch has been delayed several times in the past, one of the most expensive scientific endeavors is now ready to go. oh, humanity is new. i in the sky, succeeds the renowned hubble space telescope. hobbles e poncas discoveries were only possible because astronauts could reach out to installed new instrumentation or hubble is positioned only 500 kilometers above the earth. the new james wham telescope, however, will be beyond human reach. it will remain in the earth's shadow, some one and a half 1000000 kilometers away, tracking the planets orbit around the sun. the base of the satellite telescope will permanently face sun words, a sun shade, the size of a tennis court will stretch across its supply unit. it will shield the telescope and it's instruments from light pollution. with the wind telescope, 6 and a half meter mirror dwarfs hovels reflector it's made up of 18, hexagonal segments coated with a thin layer of vaporized gold which reflects infrared light especially well. the mirrors body is made of beryllium, a light weight metal which holds its form even an extreme cold, hard to believe. but it took only 48 grams of goal to coat all its segments. remote controlled actuators are mounted on the back of each segment. the small motors can pivot and turn them in 6 directions. to take really clear photographs, the segments will be adjusted exactly once the telescope is out in space. the main mirror collects light and reflected on to a smaller mirror which focuses it via 2 more to the telescopes, measuring instruments, probing the universe is mysteries. the universe is constantly expanding. and the further other galaxies are away from us, the faster they're receding. as the objects move away from us, the wave length of the light emitted by these distant objects shift towards the red . so web is especially well suited to capture the longer end for red wavelengths. it'll be able to look much further into the past and humble. capturing images of the universe is 1st stars and galaxies. it's infrared, i will be able to penetrate dense clouds of dust, to see what's hidden behind them. astronomers are expecting to gain totally new insights into the creation of stars and planets within our own solar system. when will investigate the remnants of its ancient past, the icy bodies plowing their way through the cosmos far beyond the planets. but for blast off, the huge james web telescope will have to be folded together like a piece of luggage. james webb, the full manasseh chief, is said to have discriminated against homosexual people in the workplace. science has signed a petition to change the telescopes name, but nasa says the allegations are unproven, so the telescope still bears the name james web. black holes are among the most fascinating phenomena in the universe. these gigantic objects, test the limits of human imagination, research into them as by german astrophysicist hind hot cancer, for instance, was recognized with a nobel prize in physics in 2020 but there are still many mysteries surrounding black holes. we meet an astrophysicist who wants to explore black holes using the james web space, telescope, dominica, violette, select will be among the 1st to conduct research using the new james web space. telescope. partain is one of 13 that had been chosen to begin work as soon as it's up and running them an hour. thank fishman, asking me to vegas when i start to really delve in astronomy and realized that what we see with our naked eye when we look up at the starry sky, is only minute part of what is actually there. it does something to you. i'm done with i'm guns and i still get goosebumps when i think about it. i think him, as he kens out, and metabolic nevada, the astrophysicist is interested in super massive black holes embedded at the center of large galaxies. as they devour the material around them, they blast out powerful radiation winds. she says, these winds can promote or prevent the formation of stars in a galaxy. the link between black holes and the evolution of galaxies is one of the key questions in modern day astrophysics. the one that my, that i who masked over glisten or touched when you think about the size of a super massive black hole, deluxe tea and the science of the galaxy, that host it, that the difference is huge. normed of us when they say, well, it's like comparing a one sent coin smith with the moon with heck lived and taught them, and yet during their active growth phase. and these super massive black horse are able to exert such an enormous influence on their galaxy. just how they do that is what she wants to understand. after all, we to live in a galaxy the milky way already as a child. dominica violence. aleck began to wonder where the edge of the universe lies and what's beyond it. because she never got a satisfactory answer. she decided to study physics and specialize in astronomy as an i fos, as if what i've about us is just play video covered vest and just so happy to have the privilege of studying the universe as my profession on the battlefield hustle. and that i get to discover the secrets of the universe. hi, mrs. only razzle often close again. and soon, thanks to the james webb telescope. she'll be able to study galaxies that are far, far away. ones that even with the hubble telescope only appear as ducks in space. the new telescope will provide a much clearer view of these objects. the light from those distant worlds has taken more than 12000000000 years to reach us. so it dates back to a time when black holes were gobbling up huge amounts of material and blasting out powerful radiation winds. the data should reveal what effect that had on the galaxies around them. does that and apples i and isn't it? the data won't just be 2 dimensional one and a picture cut out from a larger image, but 3 dimensional analysts and so going on. so in other words, there's a spectrum hiding behind each and every pixel on that 2 dimensional image is that's my day off lamb inspect home fish decked. those spectra will show how much gas is contained in these distant galaxies, how fast that gas is moving, and even in what direction it's moving. vullez select says that data will allow us to better understand how galaxies are formed. a filter, we'll like this one is also installed in the camera that you used to study those far away galaxies. it was developed here at the mox plot institute for astronomy. as the launch date approaches, the sense of anticipation is rising. the launch of the james web telescope was initially planned for 2007, but was repeatedly postponed now. dominica, violet elect, can't wait for the arrival of the 1st data ins often. and i'm, we have a certain responsibility to convince the public and the astronomical community of the james web telescopes, quality with the data, which we will obtain after daniel ben from eons on fast. therefore, we'll have to be well prepared. owned them as military sig, rudolph, hobble graduates on both of the big telescopes so called wings were folded so they can fit into the launch vehicle. there's never been a satellite with so many moving parts, able take 2 weeks to get everything unfolded and in its right position. in that time, nothing can go wrong. 6 months after the launch date, the new telescope should finally be ready to begin studying the secrets of the universe or so. and now let's change perspective and view things from above with drones. these devices have many uses, like for instance, observing volcanoes. the global drone market has been steadily taking off and the growth promises to keep soaring in the future. science puts drones to good use with collecting environmental data. we meet researchers working these flying laboratories, a disused airfield in northern germany. far away from residential areas, roads and rail tracks, an ideal proving ground for scientists from brownish bikes. technical university. they're testing drones with a maximum take off weight of 26 kilograms. extensive aerospace safety zones are mandatory for airborne equipment of the size. to day 3 different systems will be taking to the skies of fixed wing drone and to multi copters. ah, the 1st is called mass spar. it's a flying laboratory. ready as a sign is hostile form, it's a solution drawing it carries instrumentation to measure pollutants. foster missed the brit like roadside monitoring stations. this cup to monitor, sued particulate matter ozone, and of noxious substances. watched over miss bar, we'll be deployed alongside auto bonds and the like. it can be programmed to autonomously fly over a different checkpoints, and varying altitudes transmitting air quality data in real time fire radio. the branch, my team are also supporting other research projects with their monitoring drones. in 2017, 2 of them joined the polish down research vessel and the arctic. one of their tasks was monitoring the distribution of the greenhouse gas methane in the polar region. there kwan copter collected air samples up to an altitude of a 1000 meters to day. as mess bar returns after a short flight, the team are preparing their 2nd drone. it's a fixed wing model called ala dena it records meteorological data. might temperature, humidity, and wind as well as aerosols, like fine particulate matter. when you can hardly collect that kind of gotten with their bonds, his guns, and when you check pollution at ground level, you don't know what's going on in the atmosphere. it's important to understand the individual processes and their interactions. so you can decide how important which my fluids are reviewed. dixon, ala dina's job is to collect data for fundamental meteorological research. the data is essential in the battle against climate change, but also as tool to improve, weather forecasting, take off and landing, are remotely controlled. but once airborne adina flies autonomously, this drone will soon be circling above berlin, 50 meters above ground, over berlin, it will be measuring how much the opening of the new berlin brandenburg airport has increased pollution levels. but right now it's going to land and make way for a drone, which has a totally different task called arrow inspect it sport. so $100.00 megapixel camera under its fuselage arrow inspect will scan the old berlin brandenburg, airport buildings. it's batteries only last for 40 minutes. but that's long enough for it to fly. 35 meters above the old buildings and take pictures from directly overhead. every 90 centimeters, it takes a high definition picture. the resulting photo jigsaw is then transformed by a computer into a 3 d model. even though the camera only takes overhead pictures of the buildings, they're still precise enough for scientists to gauge the pitch of the corrugated sheet roofs down to the last millimeter. a decent void as could cite of us this building shows what we can do. if you had to map this roof accurately for a construction inspection, so you can take these measurements and monitor over the long term how the building changes him and kind of how a deformed ng of upside, but will both be far enough to chicago to be fulfilled to say that probably doesn't matter as far as this roof goes, lit up. but when you're looking at the rail tracks for large cranes and, and also for trains. and then you want to be certain they don't warm and for deform with time. estes's mission for full and that they don't ship with their position and dusty types. and if they do that, you notice it in time vol. would i cited her father vince, his niece, ms. later in the brown buying research institute. adina gets a new transmitter. it'll improve data transmission to the ground station. kind of technology has progressed in leaps and bounds in recent years. hm. commer, drones are being used everywhere as new applications are constantly bang developed, only half of them are available. they're becoming more shaped and they fill a gap. so there are plenty of measurements being made at ground level and from aeroplanes vessel. but in between, as this big gap of small scale monitoring that can be done, relatively shapely, skipped on they can also be used. father, things like locating dia, fawn, off to food. an increasing number of farmers now scanned their meadows with airborne infrared cameras before they caught hey, because when farms feel threatened, they ducked down and remained still. the airborne infrared camera picks up their body heat and the drone pilot can direct rescuers to the panic creatures. the multi regional ride that way, the brit further not 5 degrees left and you there was another 5 steps. thousands of fonts are sliced and ripped to bloodied shreds every year by combine harvesters. from if we'll take it over there will wide spread deployment of drones could save many young animals from a hideous fate. and this drone can shoot london's imperial college wants to use it to attach monitoring probes to trees. they'll collect data on the health of plants and remote forest areas. drones are rapidly changing the face of research. they're cheap and versatile, and brown fi technical university scientists are constantly updating their systems, giving these flying robots almost limitless potential. if i look, let is read why, of a problem with now it's your tone. do you have a question from the field of science? get in touch, send us a video text or voice message. if we answer it on the show, we'll send you a little surprise as a thank you. come on. just dance this week, terry baker from the u. s. asked us about clouds. i don't clouds fall out of the sky. there's water vapor everywhere in the air. that's water in its gas form. consequently it's invisible to us. but when warm air, which is which in water vapor rises, it cools. and then the water it holds, condenses out in the form of tiny water droplets, a kind of water dust clouds begin to form. the water droplets are so tiny that warm air can lift them upwards. we can see this principle at work in everyday life by watching a cup containing a very hot drink. as long as the droplets don't become bigger and heavier, the cloud will stay aloft. even though a cloud can weigh an enormous amount, the weight of a cloud can be determined using satellite technology. they're on board radar instruments can penetrate clouds to ascertain how much water each of them contains . a passing summer cloud can weigh several 100 tons. if conditions like temperature change and it develops into a thundercloud, it can grow to weigh millions of times because it's liquid water content increases as more condenses into droplets. the tiny droplets get swept around in the air, currents colliding with others to grow in size. they also provide a surface for further condensation. whilst the smaller droplets continue to float, the larger ones begin to lose height. on their way down, they collide with other droplets and a crate. correspondingly faster, the droplets eventually reach a point where they are so heavy. they fall to earth as precipitation. bottom line clouds do fall out of the sky, but only after their droplets are big enough to fall as snow. hail or as raindrops . oh, what should be done with looted aunt from colonial eros? a debate that has intensified in recent years, but priceless artworks on not always sacred to oh wow. i go sometimes there are people seeking to destroy them as 2001 in afghanistan in the valley of balmy on with the extreme as taliban group sought to decimate buddhist culture, but in japan, stolen damaged or even destroyed. artifacts can now be given a 2nd chance at life. putting on the final touches hit a toll she. now mickey is using a paint made of lapis lazuli. similar to that used on the original the 7th century mural was inside the balmy on caves and afghanistan destroyed by the taliban in 2001. this is a replica i had to go out, caught it at all this one year old could once be seen by the african people, if you got on it. but after it was destroyed, that meant they could no longer know their own culture. they will know suitable to them. i think those mural will be able to tell the africans about it again. all of our faculty started with i think unit on using records from the destroyed unesco world heritage site. japanese experts have created a stunning reproduction in japan. conservation is being taken to the next level at the heart of the capitals museum district and c of leading art institutions. tokyo university of the arts is bringing together scientists and artists to rescue cultural heritage. in the lab, there are making stunningly realistic copies using high end technologies. this is one of the lamps masterpieces of facsimile of a buddha statue, which is located in hor, uti temple, and nora. the actual national treasure has survived, but no unscathed elements were missing in the original, such as the hairs color or a circle of carved arrows around the figures head. the laboratory has set itself the challenge of recreating the statue to look like it did back in the 7th century . oh ok. so griffith they duck in with some of it. we measured the real statue all we scanned, it was a 3 day scanner and based on this data, we made a 3 day printed prototype of this statue. some of the, the did, the with on me will call no your, not the dc. from this prototype, we then mo, didn't measure the actual composition of the bronze looking and adjusted it to match the parent composition the same with owns and all he said with the multi okay, if we then made a rabbit like her and metal which we then corned into a cultural object, this is the whole could on with even though it started off as a computerized model. now artists are well on their way to re creating the form, as well as the texture of the artwork. here a thin upper layer of clay is being carved by hand on this reproduction of a buddhist sculpture from the mogul cave. near done hong and china's far northwest leader still go, won't bull need did with it yesterday on the scene. we believe food is our job to make it possible for the viewer to have an experience as if they had actually same the real object themselves to move on. this gave the wall for they will struction is a part of human nature. but i believe that we also have the power to restore, to put all this artist and scientist must saki masako, leads the project which uses modern technology to super clone cultural heritage and take audiences back in time to go on. this loan is shining gold. same as when it was built, there are more than an article this can be seen in both a record and full. no one you can, but i think it's very rare to find an actual reproduction like this morning for your campus children. joe was want to confirm a bit of this could be all the missing parts. i have been replenished, who actually was bit quoting model is not a problem with them. but i know what to do is this is one way to go beyond imitation by reproducing the wood carving to 1st over and filling in the missing parts. i'm done the whole cups of a choice of stuff through the photograph. these very special replicas are already displayed in certain exhibitions all over japan, but the method could have been global potential. the experts say it could resolve the thorny issue of looted art for thermal cutout properties. how's the rent the abroad and the collective being the museums. so origin, 8th country house, nothing in the cave. food park, ron coker property turn, gave the offer to choose what is you know, or clone culture appropriate could art clone soon be feeling the world's museums. first, a major cultural difference will have to be branched. the japanese people link authenticity with craftsmanship rather than original substance. they're used to rebuilding their cultural heritage because of natural disasters and their use of non permanent materials. the west seems to have a different understanding of authenticity. so more stories from the wonderful world of science and tech, fine as on the web at d, w dot com slash science and on twitter, that's all from tomorrow to day. for now, we hope you'll join us again next week for another fascinating addition of our sign ship
