w. w. hello welcome to eco india a sustainability magazine that gives you the solutions to future proof your life every week we train the spotlight on technologies that are taking us one step closer to a cleaner and a greener tomorrow. coming to you from mumbai in india over the next thirty minutes probably although my solution in the western state of budget office is making buildings a disaster see it by using traditional technology how a team of german scientists is using concrete to produce clean energy and how it might go to help solve the energy problems of the future. not every dime i speak to my grandmother she tells me about so many things sugar differently when she was younger like starting drinking water in an urban forth for instance because then when the temperature controlled devices when she was growing up and sometimes i'm amazed at how efficient and sustainable these solutions were awful story isn't the same good an organization in india is stepping into a joystick knology to move buildings disasters see they're also empowering local offices to document their practices so that they don't get lost. among you what dick's dollars. but then to my he's pretty left school after the ninth grade it didn't bode well for his future prospects you know what today he teaches students sustainable cup and. with my previous shops i would work all day but never have a sense of for a chief and a feeling of pride in having i mean something there was no sense of purpose i was a deliberate and i had constant sense of disappointment today i'm a carpenter and the past times i'm skint after years training at car because i can now make anything i'm asked for a table a roof anything. but here. the other three were. pretty good. but my history now works as a trainer act. as skills odeon did residential school in in the western state of gujarat. carpenters from around the country are dreamed here in sustainable craftsmanship often borrowed from traditional indian wood work and construction fees. at the artisans live eat and study together for one year the school attracts dropouts from the formal and. occasion system. or do year they learn carpentry and masonry alongside the skills needed to negotiate decent prices for their products. this school also teaches them principles off entrepreneurship. shallow was born out of the nonprofit who not shallow foundation in the vehicle the devastating earthquake in that region in two thousand and one which gleamed over twenty thousand lives and left millions homeless. once the rubble was cleared and the reconstruction effort began dozens opted to use sustainable much utile such as storm. pallets and bamboo instead of and the g intensive industrialized materials like cement and steel. but never to go both muslims and considerable good to us here. on ash i love was falling too fast and it did does a new collaboration's and empower sustainable building practices traditionally used by the local. the local technologies and marketers that we use are inherently more eco friendly than processed material because there's no processing and water does nor. govern darkseid being released by users. so they're not going soft you call friendly. indicators. first is while producing that material how much resources are abusing and how much i missions of carbon dioxide that does happen. the second is a volume you've released our technology where do you know what is the energy consumption of the building itself. for the first part discord and warded energy of the material the second part is how well the building is consuming energy because of the technology. is it more climate friendly that means is that and what i meant inside more user friendly without using is going to all in france maybe. the whole notion of foundation has helped build close two hundred fifty thousand homes and worked with many disaster affected communities in india including in good gerard jumbo and push me to be hot and british helping rebuild homes that are environmentally friendly sustainable and disaster prone. in good outscored she region for example these sound backed stone foundation earthquake resistant. sustainable bamboo and brick mason injury but that wrap trap bomb proved popular in bihar. buildings are also cost effective. especially given that many of them are funded with government grants. to see very few or very less. and we try to rely on the things that are available about stalling or soil. and if that are available there then automatically their transportation cost goes down the processing of the material is not there because you don't need a second processing of the materials for the cost was down and that sort of the artisans are also locally available even or getting artisans from outside and just makes it really cost effective. organization has expanded into affordable housing projects do including slum jihad to live. in a country with one point seven million homeless people sustainable low cost is an urgent problem. foundation is part of the solution. older technologies are often the building blocks to developing new breakthroughs take for example our mix story a team of scientists in germany has developed a type of concrete that mimics the natural process of for the synthesis which is as old as the earth itself to generate energy imagine if every flat surface and every building in the world could help do this let's find out how you. know more than three billion years plants have been absorbing some life with the help of a green pigment called chlorophyll during photosynthesis the leaves transform the light into energy allowing plants to grow. this energy is truly green. and. at the university of castle scientists are trying to use the same principle to generate energy a team of architects artists scientists and designers are working on a building material that will transform sunlight into electricity like a solar cell. what i'm on. there using ordinary concrete as their base the researchers mix it with graphite so it can conduct electricity. after it's hardened the special concrete can function as a positive or negative pole. is an artist boston close to an architect they came up with the idea of using conductive concrete to generate solar power. movement he is need see what you see here looks like ordinary concrete but what's special about it is that it's sensitive to the touch as you can see and that's because we've made this concrete capable of conducting electricity and this conductive concrete is the basis for our solar concrete. to give the concrete the desired characteristics decide to spray on various layers of colored liquid the result is a dye sensitize solar cell that produces electricity through artificial photosynthesis the order in which the wafer thin layers of color are applied is all important. with them on the five shift if you combine the layers correctly you end up with something that functions like a photovoltaic cell one layer contains dye pigments when the sunlight strikes them electrons are released and current starts to flow. to improve their di sensitize solar cells the researchers conducted long term measurements in the law a single solar cell initially delivered only millivolts what can that supply over one volt of electricity if you covered with your hands a charge fall sharply and rises again when light hits the solar cell. the cells of fission see is currently just more than two percent that's not much but it's a start. solar concrete are discrete is so interesting because it's really easy to produce it's environmentally friendly. and can be used on large surfaces and maybe one day in the future all the smooth flat surfaces in the city could be used to produce electricity. the more cells that are sprayed onto a building's wall the more electricity you can produce to do this the individual cells need to be interconnected under ideal conditions a surface area of one square meter to generate twenty watts of power. the researchers didn't only come up with the design for the cells they've also developed a façade robot you can scale buildings and spray them with solar cells taking the concept to the next level. from one fascinating technology to another law when you're flying kites could help solve and as you problems of the future a startup in germany specializes in flying wind turbines and a kites which harness wind power while in flight and there are many benefits to this technology let's take a look. this kite could help solve the energy problems of the future. it aims to generate electricity by harnessing high altitude winds. the busy. servatius here develop the technology and scale it up to rival today's wind turbines. we're starting small and have a long way to go while always starting over. for now the kite is attached by cable to a telescope a car mounted on a truck when fully deployed it should soar high in the sky trials are conducted at an airfield in the country saucily but the team is based in berlin. and. the big challenge right now. he's programming the computer to steer the kite with cables like these. the generator that produces the electricity is in this truck. in off grid locations the dirty diesel generators are often used in are quite technology could replace them. today's wind turbines are mounted on towers the kites tethered to lines would rise to a height of two or three hundred metres where the wind is stronger and more persistent than closer to the ground. the intercut laboratory is on a campus of the technical university of berlin the engineers started experimenting seven years ago with fabric kites. when the kite goes up the lines on furrow and turn a turbine which generates electricity. then the kite is pulled in again which consumes a very little power. it's like a yo yo going up and down. the team has moved on from fabric kites to ones made of carbon fiber. they build them and all the technology themselves and they're always having to redesign and optimize. as a motto is also has to make as many mistakes as possible in this short a time as possible but only once it is why we have to learn and the mistakes make us smarter and then make the product safer. as it is causing this is a lost details for the wingtips right to do. the wingtips are also made of carbon fiber. the material is very light and stable but it can't withstand everything. like. structures can survive a hard landing unscathed. they've been working on carbon fiber kites for two years now and already over a million euros on prototypes. the developers drive out to the airfield they haven't made much progress with flying yet. they often start at midnight when there's more of a steady wind. we get more flying time and it gets less stressful so we can enjoy the fruits of labor. they need to fully automate the steering of the kite but getting there is a slow and complex process. trim a bit. after a year of testing takes off steered by the cables and stabilized by the computer. now they have to program the computer to carry out all flight maneuvers autonomous . trickiest phases when the kite is still really close to its base the software has to be very precise little mistakes get punished in a big way but we've been practicing for so long that it's become routine. is still flying just a few metres away from the telescope. but once the computer learns to guide properly it should start to fly higher and generate electricity. earthbound wind farms. shifting focus. by single crops leading to a loss of biodiversity a group of hobby god knows in austria is trying to save and grew for crops from very rare seeds and helping bring back a variety of fruits and vegetables talks to be unavailable. michele to her grows twenty different varieties of beans in his garden every year he tries out new types. these varieties he says were eaten way back in the middle ages these days many of them are no longer readily available. produce the seed varieties in the quantities that i want for any border on average of beanstalk has three plants probably from one plant on so i can get enough seeds for myself and a further seven or eight people to. the australian initiative i should know our supply seemed to hold the garden and the group wants to preserve as much biodiversity as possible. many of the older varieties are more resilient than commercially grown fruits and vegetables the harvest tend to be longer to more than sixty kinds of tomato grow hair says. right now she's testing the so-called russian cucumber. this variety can be harvested until late autumn and what's more it's also resistant to a common fungal disease i'd have thought the old varieties haven't been intensely farmed so there's more genetic variability a greater range and that's why they're more adaptable. if your chin that it potential is too narrow you can only survive in certain environments but not in others. older varieties have this potential. because she has long devoted himself to taking care of these treasures there are more than five thousand seed varieties hands collected over a period of three decades. and since they're so robust they could play an increasingly important role in the process of adapting to climate change organic produce isn't garden is also interested in these older varieties they perform better in soil that hasn't been sprayed with chemical fertilizer. trying to grow these five thousand varieties in a five year rotation it doesn't always work that we're trying to do a thousand a year we always take stock and say what variety is this how adaptable is it what's the produce like we've documented all. bill get that man is in charge of the guard not weekends visitors come here to discover varieties they've never seen before in the supermarket. and they find out how to plant and cultivate them. touching smelling and tasting is encouraged here the aim is to awaken an interest in preserving biodiversity. of upfront that are going to see every plant has its own story its own way of being cultivated you know came by when you're really know a plant you know these things. from this investment you a one team of any loss of knowledge is an impoverishment but when it goes beyond a critical point society loses out to. itself. to prevent that from happening benyamin is doing his best to spread the word he's the chef at the noir show god restaurant and cooks with produce from the garden over the last century there's been a seventy five percent reduction in older forms of curl. it's hoping to make more popular again. when i always say i've managed to get around quite a bit angel i thought i knew most fruit and vegetables but then i encountered a huge noise and i noticed i knew only a tiny portion. he uses his newfound expertise to whip up tasty dishes they've become known all over the region good food and good times this chef's recipe for preserving biodiversity. now to a story that will bring my. i retired aircraft engineer it is giving underprivileged children in his community a chance to fly high and providing an experience that would seem like an impossible dream to many like them. the other that got off with it it's a day these children will remember all their lives for many it's their first time aboard an aircraft. but this plane won't be taking off. on a flight to nowhere is an airline with a difference going up with all the other worth it offers passengers an environmentally friendly taste of flying because this plane is never leaving the ground oh i don't know the other passengers are treated to a full in-flight experience. they receive boarding cards. safety briefings even refreshments are served on board it's an eye opening experience. i've seen planes in the sky i used to think they were really small but now i know they're actually huge. i now want to fly to london. beautiful to see. some lucky passengers even get to visit the cockpit. the man behind the project is the harder chant copter a retired aircraft engineer by les sold his land and bought the decommissioned airbus a three hundred back in two thousand and three for six hundred thousand rupees that's about seven thousand euros a real bargain he charges people according to what they can afford as little as a few euro cents or even nothing at all for the very poor. i belong to a very small village. and i never expected i'll be coming then you know and then i'll be in their lane and then people from my village you're putting that off and they were not able to that so that was actually a basic idea and basically look at motivation that i work for the sake of the poor people. not far away a busy main road that runs parallel to the runway of delhi's international airport it's the perfect spot in the evening to watch planes land. even though air travel puts a lot of climate warming carbon dioxide into the atmosphere the age old dream of flying remains a desire for the poor migrant workers here. it's my dream to someday take a plane and fly to my village in bihar but that's only if i manage to scrape together enough money for a take out. further on it a relic crossing regulars here swear that this is the closest you can get as the turbojets take off. god that in my village the planes are really high up in the sky but from here you can see them up close it's an amazing feeling. why did. we may not have the money for a plane ticket me but that doesn't stop us from dreaming about what it must feel like to be up in the sky. back on the flight to nowhere person just simulate an evacuation to finish the experience. rarely has an emergency situation seemed like so much fun. i hope you enjoyed to be stories we've been to many more such stories each one giving us a new quilt for a sustainable future good bye and have a wonderful week. this is. going to. come under the hammer. prices. that's today's art. and

populated urban centers solve the living space problem in singapore. team is developing solutions together with local universities and a project called the future cities lab. one of the first things you notice here is how heavily built up singapore is but that it's also astonishingly green. that verdant sea is largely down to visionary city planning rules here stipulate that any land used for construction has to be at least partially compensated for by green areas in and on the structures the future cities lab is looking at how people in green high rise buildings like these live neighbors know one another how does the vegetation affect the city's climate and how's the quality of life here. future cities lab research director tom a short five lives in a green high rise with his family the interlace is viewed as a successful example of this type of architecture. its structure doesn't just rear up it's also interlaced horizontally. functional spaces are staggered over various levels communal areas on one the swimming pool on another and courtyards on yet others. are hitech you for an architect the mission is of course to create decent living space in a high density environment and i think the interlace is a very good example of how you can create that high quality of life while not accepting that high residential density will have negative effects. on coal from their boss. the scientist says that the people who live in the interlace like it and it also provides opportunities to participate in a neighborhood and community. that's a difficult and delicate challenge in a high rise. buildings in singapore have proven a lot less successful at mastering at. social scientist michelle zhang as also part of the future cities lab project she's looking at how green spaces are used and how they contribute to community building . people to meetings even if what you think of. this garden is used mostly by the people who live here like this retiree who comes here every day for a workout he's proud to show us the apartment he owns in the block not only does it have a great view he says it's eerie enough that he almost never has to turn on the air conditioning. like him most people in singapore live in public housing. places like sky though three thousand people live here around the same number as an average village and the idea is reflected in the development which groups blocks of eighty units into villages. the green areas in sky vale are meant for communal use but the project's roof terraces are nearly empty apparently building a community involves more than just providing spaces for it to happen. it's not just a provide a space and going across there we have to consider what kind of people what they use like to use says space what kind of a need stay. and what kind of activities. even though the terraces are attractively laid out and could easily serve as areas for interaction they remain empty if certain key conditions aren't met. well we did a survey we understand that people conserve ery much as. part of temperature humidity direct sunlight and the noise if we cannot find a way to improve and then it's very difficult for people to go to the upstairs to. the pinnacle is a complex made up of over eighteen hundred apartments home to about nine thousand residents around the same number as a good sized town. the roof terrace is open to the public you can just stroll around and admire singapore's skyline. fifty floors above rolling traffic a miniature biotope has formed here. still big questions remain even if life can be made pleasant in vertical spaces aren't we humans at heart more come. down on terra firma are plants on a roof really an adequate substitute for green spaces on the ground. simmons want to go out into nature ground to others specialists have said that time and again. that means that humans are oriented towards green on the ground towards feeling real soil under their feet. that said humans have changed over the millennia. we've accepted certain influences. so i also think the ground well is like us accept it if the ground whereon happens to be up on the twentieth floor of a building. finding common ground between human nature and vertical living a challenge for architects today and in the future. on facebook we asked what are the biggest problems facing your city. mom and says cairo has so many problems he doesn't even know where to begin. hilda ellison villain wave or a city of one and a half million that has no proper sewage system. that has lots of water but ninety five percent of it is polluted and there's little political will to change that. frederick says nairobi struggles with traffic emissions housing estates that are filled with smoke as a result of garbage burning and plastic that some potholes everywhere which also clog up drains. zain and this is khartoum is a quiet says he between two rivers which give the place a special charm but one problem is the lack of cleanliness in many areas where it's only it's in concepcion in chile where rush hour traffic is a big problem he'd like to see an overhead railway system to relieve the pressure on the streets. thank you for all your common. most big cities struggle with traffic congestion and car emissions could images like these one day be a thing of the past what's needed is an environmentally friendly alternative to gasoline and diesel. which could come in the form of electric vehicles we meet an engineer who's not only designed his own electric car he's also forging ahead with manufacturing it's. there it is again acceleration you could use your driver's license in a car like this you just want to speed up a little but then you look down and it's just topped the gas but now i'm doing over seventy. that's not good in traffic. certainly not in town anyway going to shoot designed eco at the city car it began as a study at athens technical university the professor and engineer was determined to see his model go into see we spit action but established car makers weren't interested. it's really annoying for scientists when good concepts they've developed over a long period just disappear into a bottom drawer so we said not with us i was getting all of this but i thought come on you can tell this i wanted a mini porsche or a porsche killer so to speak when anyone can afford it. he go might indeed an oil luxury sports car makers because it can be had for as little as sixteen thousand euros sixty eight thousand less like comparable models because she didn't just build it from scratch he also set up a tailor made production line one big advantage electric cars work with far fewer components than traditional feel driven models. where a combustion engine production line and the entire building not be too small. fewer parts equals fewer potential problems as well as low investment costs for components automation and assembly. working within the car industries traditional structures are serious that churns out fewer than one hundred thousand units a year just isn't worth while that's because the initial setup requires such a big investment that you need huge production runs to turn a profit here we're showing that producing just ten or twenty thousand cars a year can still be economically viable on one saving using an alan minium frame instead of the standard integral body that saves the costs of expensive presses for bodywork components be like. drive is made by a german company. based company couldn't make an electric drive that won't last one hundred years that's what's special about electro mobility something not possible with internal combustion technology and we've built a body that will also last that long it looks so good we don't even painted it can't rust it doesn't soften that's the basic plan for a car that can last for a century if that's what you want. he doesn't have panels that all made of thermoplastic and i'm ready to mount so the ego pans doesn't need painting facilities. if you can produce a painted surface like this and it's also extremely durable it takes four times the normal force to scratch it and then you can hardly see to scratch because the material itself is colored there is no primer coating that makes it a wonderful material. but the part from concept to serious production from scientists was anything but wonderful. i think during the nearly four years since we set up the go mobile there have been six or seven disasters where we could easily have given up. just said ok that's that. but you know what's really great about that what my team here has been through after you've overcome the problems they all appear wonderful in retrospect was going to shoot is currently building two new production holes soon they'll be manufacturing an electrically powered berth and further ego models. there goes. and again. and again. most of the time linking is an automatic reflex linking helps to fend off germs and protect our eyes from sunlight. it also spread steer view it's which helps ensure that the surface of the i doesn't dry out. all good and well but it does still leave one question. every few seconds everything goes dark around eleven thousand times a day we should be seeing this but we don't so what's going on in our brain. wants to find out the neuroscientist at the german primate center in putting in studies perception. that we don't notice the darkness when we blink is because the i actually reacts extremely quickly to change. it can perceive a black image lasting just ten milliseconds and the dark phase of a blink is much longer about fifteen times longer. so we ought to notice it. for this good homes and for the brain one hundred fifty milliseconds or an incredibly long time when you close your eyes during a blink the brain isn't getting any input so it fills up that gap food and gives a look of. as a result you don't notice the one hundred fifty milliseconds of darkness but what fills the gap. to find out shits it how to watch the brain in real time as it processed visual. but he needed the help of electrodes to do it. the neuroscientist got the opportunity to carry out a test on epilepsy sufferers who had had electrodes temporarily implanted in their brains to treat their disease one group had electrodes in their prefrontal cortex is. the prefrontal cortex is in front here traditionally it's associated with your higher cognitive functions for example how you concentrate how you retain things in memory and those are the functions typically associated with this part of the brain not perception but we suspected that the region does play a role with this feeling in effect such as when you blink. combustion. the electrodes read just a neural activity while the test subjects look at two images one after another showing lattices of dots. they have to decide whether the tops are oriented vertically or horizontally or diaconate harder than it sounds as the arrangement of the dots is ambiguous just picture vertical horizontal or to acknowledge using the green point the subject selects diagonal to the upper right. second picture. again diagonal to the upper right. most of the patients showed a kind of memory effect on the image of the lattice they saw first had a strong influence on what they said they saw in the next image. and those who chose vertical in the first picture and nearly always chose vertical in the second picture two at that moment the nerve cells in the prefrontal cortex were highly active even though the image is stored in this part of the brain. only one patient made decisions at random in her case part of the prefrontal cortex had been surgically removed. the composition she couldn't remember what she'd seen in the first image so we concluded the information from the first image couldn't be merged with the information from the second which is what would normally happen. so it seems the prefrontal cortex is necessary for us to perceive images seen one after the other like the use the separated by a blink. if outlet is red white i didn't say it. did you have a size question that you've always wanted alan said we're happy to help out and send you to us as a video text over as well if we answer it on the show we'll send you a little surprise as a thank you can i just ask. chuck well as you know marco from nigeria wants to know what is d.n.a. . it's in every cell in the body along molecule that looks like a twisted rope ladder and it contains all the instructions for making a human being. its rungs are made up of four different building blocks you can think of them as letters that can be used to create an infinite number of words what we call genes that endless variety and the d.n.a. is what makes each and every one of us unique. some sections of d.n.a. are like the different departments in a company that keep business ticking over this and for instance borders to the cells manufacturing facilities to make and deliver more of this or that product. the instructions in coded in d.n.a. are used to make a vast array of proteins and they control every aspect of metabolism and the body. d.n.a. is found in every species on earth. that's made it a powerful tool for determining the course that evolution has taken since life first began. the development of the tree of life is similar to that of a real tree whose branches continuously split and diverged. researchers used to determine how species were related by comparing their physical characteristics for example by looking at whether an animal had wings or not however that can be misleading. but comparing d.n.a. can help clear up mistakes because it provides a much more accurate map of degrees of kinship between species. some ancient human d.n.a. has survived in fossilized bones and teeth for over one hundred thousand years. but gave researchers the idea to use the molecule as a way to save other kinds of data. when d.n.a. is dried it looks as in conspicuous as flour but a single gram of it could contain as much information as a trillion c.d.'s a medium that takes up little space and doesn't require any power. researchers have already packed artificial molecules of d.n.a. in tiny glass balls for saving and reading data a first step towards making the technology a reality. do you have a question or a comment visit our website or drop us a line on twitter or facebook. speaking of d.n.a. a colony of bees has a queen bee male drones and female workers whether a female becomes a queen or a worker is determined by the food she gets as another not her d.n.a. . nature does have many surprises in store. so surprising the unusual role being played in the south african conservation project. in the middle of the south african bush right next to kruger national park zoo all of jests robin cook and brownie. have set up fifty beehives. the two conservationists are testing whether honeybees can protect selected trees inside the park from the park's largest residence elephants. just like people elephants don't like getting stung they have an acute sense of smell and hearing so one hint of a bee hive and they're all. and the reason we're doing that is that in our protected areas here in south africa we've got a build up of a lot. and danes are concerned over the impact that they may be having on our large tree species and so we're trying to find ways that we can mitigate the effect that elephants have on trees and thereby placing honeybees in these trees we hoping that we can find a new method to actually protect the trees from elephant in fact. while elephant populations are in serious decline in other parts of africa the numbers are growing in south africa and nature reserves a fenced in and equipped with also official ritual holds protected and well provided for the big animals have flourished so much so that they've become a problem the elephant stripped trees and shrubs naked often up brushing them in the process and destroying the habitat other animals and plants in the park rely on elephants a particularly partial to one of the park's largest trees the marina. trees are a highly sought after tree by elephants and that's because they've got a lot of forage for the elephants and we're seeing a lot of impact on these trees and for example in the study site here we've seen a decline of around thirty five percent of the military since ill effects have been in the system so i'm really trees are very important in our ecosystems they provide a lot of food for species that provide habitat and so we know them as a keystone species. the elephants often flatten the my religion just so they can get to the leaves but so fall them really is with bees living in them remain largely untouched out of fifty trees only one was damaged during the past year. cook speed project is a new approach in park management in the past a large number of elephants was simply culled nearly seven hundred thousand was shot dead in kruger national park to keep the population stable and protect the vegetation so when it comes to managing the effects that elephants have on large trees there's been a mindset shift from controlling elephant numbers and saw. as was previously thought to mitigating the effects that they actually have on the trees so you could have courses on a large scale where you could try and manage a different distribution. managing the facts or managing a large trees and solves protecting the large trees themselves. with the beehives. hoping to control the elephants movements by keeping them moving when the animals stay in one place too long they can inflict extensive damage but above all the conservationists say bees are the perfect way of keeping elephants away from trees when one of the big animals has ripped off that bark they can fall prey to other assailants like termites in the villages around the park people have little experience with bees many are afraid of them and attitude running to calais is working to change he plans to start keeping bees in his village and to train some of the local residents as. we've heard. from a. lot of these. producing honey about because. back inside the park the conservationists have found another way of reducing elephant numbers in problem areas they've laid dry a number of watering holes that means the elephants have to keep moving to find fresh water relieving the pressure on the local ecosystem but smaller parks don't have that option so there is growing interest in the results of robin cook's experiments with bees he believes it's a groundbreaking method with huge potential but we would love to see it applied to new species particular. species which elephants are often such as the bad species and then to see if it can be applied to other projects such as the vault project to see if we. to protect trees with faults in this in them using african honey bees and whether that relationship will not work. they should soon find out the first times already in place if it all works out the bees could in future protect not only trees but also the birds and animals that depend on the trees for their survival. that's all for now the next time we'll look at spiders a creature many of us are afraid of but scientists say protein from a spider's web provides

w. literature list a hundred german must treat. hello and welcome to drive with an e w motor magazine this week a trade fair for tomorrow's technology points to the future of mobility. a compact is u.v. that really can go off roading this go to caracas scout and b.m.w. is due luxury s.u.v. the x seven. exactly twenty years ago b.m.w. launched its s.u.v. series with the ex-wife now the seventh and largest model in the family is hitting the streets the german car maker claims the x. seven combines excellent off road performance and handling with all the creature comforts it's assembled in spartanburg in the u.s. state of south carolina. doesn't get a car test i know guys you know versus what strikes you instantly about the x seven is has enormous grill and sheer size overall it's over five meters long two meters wide and one point eight meters tall that makes it a full size s.u.v. by american standards and the same class as the cadillac escalate or the mercedes benz g.l.'s nobody in germany would want to vehicle besides that lots of customers want them in the u.s. and china he says or at least b.m.w. hopes. the x seven is built. on the x. five platform but none of the parts of the ex-wives body are used in the new model a single glance shows why that's no surprise the x. seven leaves a much runny or more opulent more imposing impression it seems it says i don't says seven scenes here all well and good but what's key is getting into and out of a car like this and hatch to be easy would more compact s.u.v.s that sometimes awful but it's no problem with the x. evan and the seats in back can be adjusted electrically another good thing he says is that even tall people have plenty of leg room in back. of oxen to mention their plots. a gearshift made of glass is just one example of a luxury on display in the x. seven's interior. there's also plenty of soft weather and high end wood trim and passengers really have room to stretch out. for the second row of seats customers can choose between a standard bench or two captain's chairs. the x. seven is twenty five centimeters longer than the x. five says ryan old which means there's enough room for a third row seats but if you're carting around seven passengers as you won't have much space left over for baggage when there are only five in the car on the other hand there's loads of room he says especially when all the rear seats are lowered if you doing that frees up to two thousand one hundred liters of cargo space. and i will not lead to a woman. and germany x. seven customers can choose between three different engines i know hold is testing the gasoline powered x. drive forty i although the s.u.v. tips the scales at two point four tons it's able to hit a hundred kilometers an hour from a standstill in just over six seconds but the model is a dinosaur when it comes to fuel efficiency and burns through at least nine leaders for every hundred kilometers on the road yank seven comes standard with a twenty axle air suspension and an automatic sofa leveling system that ensures top notch control and comfort even on challenging terrain what if so how does it drive as reinhold well it says agile as its little brother the x. five adds down to its great chassis and torque vectoring to each individual wheel as well as the rear act. steering he suggests taking the trim line that includes the panorama sun roof because it lets you simulate a starry sky at night it's almost like being in a rolls royce he says. there's a nice control panel for the force own climate control system and the seats offer a range of massage options. we think seven's interior features are based on those in the x five drivers can use the central console to choose driving modes from sporty to comfortable offloading programs or option i know says the x. seven is proof that b.m.w. can also do a full size car though it's only no two full size for german streets and parking garages but he thinks there are markets where it'll prove popular the americans and chinese love big s.u.v.s are c.d.'s so fifty thousand units of its g.l.'s annually and b.m.w. wants a slice of that pie he says the model ought to operate through other variants of twelve cylinder option and a plug in hybrid but so far the car maker isn't planning to make either but it's about. the his good luck. and sure many prices for the luxury s.u.v. started just over eighty four thousand euros for the big question is whether the concept has legs because another trend has been gaining momentum among consumers for years a growing concern about climate change. and about a journalist the man o'shea for says the mobile world congress in barcelona is the industry's most important trade fair not just for mobile communications but also for mobility and that's why not only manufacturers of smart phones but also why the likes of b.m.w. and say that show up there so. it's time to take a look. at the fair has been held since one thousand nine hundred eighty seven and initially in london the host city has changed several times since then it's said to be held in barcelona until at least two thousand and twenty three. c. slogan this year is the urban beat journalists from all over the world attend a press conference at the spanish carmakers booth. and this is what they're waiting for the mini mo the concept car is intended above all for fleet customers and car sharing providers. i wish to get in monaco says a big topic here is micro mobility covering distances a less than ten kilometers say it's come up with a mini mo for that like others in the segment it's a battery powered but it has a big advantage you can swap out batteries so no more long waits and charging stations. the empty battery pack can then be recharged added charging station while you're driving around in the mini mo it has room for two people and can recognize and adapt to the driver for example for sixteen year olds the maximum speed can be limited to forty five kilometers per hour and stead of ninety with a length of two point five meters and with a one point two meters the meaning occupies just three point one square metres of space much less than most cars but there's much more to see at the fair. one toppy man will find very interesting are these foldable displace they're also interesting for car manufacturers because they open up new possibilities they no longer have to work with displays that are flat or slightly curved but can adapt them to surfaces as needed. in the future even sharp edges can be used as a display. which means a lot of flexibility for interior design. in manila says another important topic at the show is five g. the next gen mobile data transmission with you download speeds up to twenty gigabytes per second it's way faster than the current four g. or l.t.e. that's important for the car sector because of autonomy is driving or a lot of data has to be transferred from a car to the transmission tower or between cars and so a new standard is needed and that's five jean says. it also increases transmission speed so cars can exchange information as quickly as possible with each other. as people that want to us says the fare doesn't just offer visions of the future but also mobility solutions that are already available like this say x. as kick scooter it's electric has a twenty five kilometer range and can hit twenty five kilometers per hour imagine leaving home taking the scooter to the train station and then with you onto the train and scootering from the train to your workplace you don't need a car or a parking space so it's easy to fear provides a taste of the many new forms mobility will take in the future. says go to caracas been out on the market since mid twenty's seventeen by the end of last year one hundred twenty two thousand of them had ruled out the czech car makers assembly lines now there's a toned up furnishing of the compact crossover s.u.v. a caracas scout skoda says it handles even better on rough terrain and thinks it will draw fans looking for transport to more remote locations and the great outdoors. aren't just a yawn baker says s.u.v.s are supposed to be sporty off roaders which means this special off road trim package so. house seems so little redundant nowadays most two wheel drive lifestyle as you use can barely climb up on the curb when you're parking he says so maybe the correct scout actually does make a kind of sense if it really can deal with off road terrain that's what he's going to find out today and yet that's one of. the boasts that the correct scout really is built to deal with the rugged terrain is underlined by a range of alterations new underbody protection now shields the engine from being bashed out in the field striking wheel arch linings and special skirting provide extra protection from any stones and gravel thrown up along the way the trunk offers five hundred twenty leaders of cargo space lowering their rear seats expands that to one thousand six hundred thirty leaders. and up that's going on gun says the view from the driver's seat is nice and high typical for s.u.v.s and visibility up front is good steering is light and direct and suspension is more comfortable than stiff but it's stiff and have to keep the scout from listing in curves all in all it makes a good impression. two engines are enough or for the model a two liter diesel or a one point five liter gasoline powered version but with put out one hundred ten kilowatts of power this cow takes nine point three seconds to go from zero to one hundred kilometers an hour. the bare bones version costs around thirty six thousand euros younes test car with wants of extras would go for over forty seven thousand five hundred euros and i have a gun says all wheel drive is standard for the model which is only right in a car supposedly made for off roading but it only kicks in when the front wheels start losing traction otherwise the scout runs on front wheel drive to save fuel when off road mode is turned on. and he says the car react more slowly when he hits the gas and off roading assist programs are activated that help you keep control going down the steeper slopes the about an arc to the fence about it. with all those bells and whistles the correct scout does well on dirt roads but constantly calculating optimal torque distribution to both actuals the car's drive control unit ensures good traction and control at any given moment the scout has higher ground clearance than the standard garage and is series package includes a suspension optimized for off roading. and soon if you don't like the wood trim inside although he generally isn't a fan of it but combined with the scouts exclusive seat upholstery and brown tones it compliments the rush to go outdoors the look because it's also. but if you want things a little more high tech inside you'll have to pay for. build a standard package does include a nine inch infotainment display and adjustable ambient lights and lets you alter the lighting scheme in the interior to suit your own taste and it's a nice touch in combination with the scouts brown seats. let's come up at the end of the day he says youn the scout isn't really true off roader or mountain climber it's and cheerier is too nice for that and the hard plastic cladding wouldn't be able to withstand serious pelting with stones for long but whether it's standard four wheel drive and rough terrain package it might be an alternative for someone. drives a lot on unpaved roads. that's faced in the market for a mid-range station wagon is competitive says car tester on the left because there's a choice for every budget whether it's expensive models like the a four avant practical ones like a school in a suburban or all rounders like the v.w. not forget the ford mondeo or opel insignia the key is joining a crowded field he wants to find out what the sporty korean wagon does better than the competition and what not so much. here has recently revamped the optima sports wagon and the most important improvements can be found under the hood available engines already comply with a euro sixty tempi emission standards which will become binding on all new cars sold from september onwards among them are two new one point six liter power plants a one hundred kilowatt diesel and an agile economical one hundred thirty two kilowatt turbo gasoline engine today brownie's testing the diesel engine in the top tier g.t. line trim. there up to my front he says the optima dries very comfortably and above all quietly over long distances what sets it apart is its look it's typical kiya but by no means typical for a mid-sized car. the facelift is most noticeable on the modified front bumper and redesigned headlamps fog lights and early daytime running lights the design of the eighteen inch alloy wheels has also been refreshed this sporty year g.t. and chichi line trim lines feature black glossy exterior mirrors doors. hills and side air intakes. besides twin tailpipes a highlight of the rear is the sleek tail lights. bije t. line also has an electric tailgate the vehicle recognizes when the driver is waiting at the rear of the vehicle and the tailgate opens after beeping three turnips the luggage space in the rear is a generous five hundred fifty two leaders which expands to one thousand six hundred eighty six leaders with the rear seats folded in on. the g.t. line interior combined sportiness with luxury is comfort the quality of workmanship is high and there's no reason for kenya to shy away from a comparison with european competitors. red seams on the leather seats emphasize the car's sporty flair. the new one hundred kilowatt one point six leader diesel with three hundred twenty new meters or torque replaces the previous one point seven leader c r d i it meets the euro sixty ten standard thanks to s.c.r. exhaust aftertreatment and key it takes eleven point eight seconds to go from zero to one hundred kilometers per hour and as a top speed of one hundred ninety three and germany the optimist sports wagon with g.t. line trim starts at just over thirty nine thousand euro. the charge for romney says the automatic transmission changes gears smoothly the one hundred kilowatt one point six liter turbo d. well does what it's supposed to he says but compared to competing models it lacks some liveliness responsiveness and pulling power but it's fuel efficient and burns a maximum of six liters per one hundred kilometers. and keeping with its dynamic appearance the new up to most sports wagon suspension provides agile handling and especially stable front suspension and the cars and fish and multi link rear concept in short high right comfort and little engine noise to kill ronnie sums up by saying this key is the perfect companion for those who can live without the prestige value of a luxury brand and are mostly interested in practicability economy and especially value for money. the entry level up to most sports wagon is already available in germany for just under twenty six and a half thousand euro s. . in the early one nine hundred sixty sirup was experiencing a baby boom renault boss pierre dreyfus responded with the development of a radically new interior design for a midsize car. to mislead the car to stick a stockpile or recalls what drive has announced to his team but you've got to see things in a new light a car cannot always consist of four seats selfhood in a trunk we've got to see it as a single space but the result was the one thousand nine hundred sixty one renault are for a revolutionary and innovative compact car and in one nine hundred sixty five renault launched the our sixteen a midsize family car with a hatchback a large trunk lid and flexible interior and eight defy meaning. during the design process the engineers had almost total freedom the only requirement was a front wheel drive and to. for years the newly established design department progressed from a prototype to a production model are sixteen to build a new production facility is. in france. just important for cristo says when the are sixteen was launched the media were impressed that they praised the cars a benchmark and symbol of practicality and held it up as a challenge to german engineering even today the car is still a smooth and comfortable right granted it is steering is a bit squishy and going around curves can be nerve wracking but overall this is a great set of wheels he's done up and also guns and what about us guys a good fit. and so the renault are sixteen became an international hit initially sales figures doubled year by year by nine hundred seventy two seven years later renault had sold over one million are sixteenths. renault kept producing the car until one thousand eight hundred continually developing new versions including a luxury t.x. model with around seventy kilowatts electric windows and five speed manual transmission. as open minds the first time says the are sixteen has the unique design of the two box design is a particular feature that it broke with a conventional design at the time where vehicles were divided into three boxes and vientiane in front of the passenger compartment and the trunk and back in contrast they are sixteen fused the passenger in trunk space allowing for a flexible interior with up to seven different variations and that's a smith i had to stop in order to become to flexible to take this in the alps this took zebra vance on smokers' cut isn't that it. was that there's the normal position for when you're just driving tolls and the position for transporting large items to the back seat can be folded away entirely. then there's was this the only one way to relax and spawn should. want as well as the position for sleeping and cuddling. back then there are no sixteen at one of the most spacious and comfortable interiors of any mid-size car neat features like the continue was ventilation grill and a classy ashtray expressed a typically french charm. another clever feature metal rails along the flared go to roof they provide stability and function as a rule bars oddly the torsion bar suspensions were installed one behind the other making the wheelbase six centimeters longer on the left side than on the right. is a more current tester christo says and there we find if i was spared fire as well as a redesigned one point five liter four cylinder engine with forty kilowatts engine block cylinder head and gears are made from a lightweight aluminum alloy it's good to achieve better balance the gears are located ahead of the front axle of the engine sits behind more typical of modern sports cars to get so the reno was actually ahead of its time because as often committed more talk to off north by more down spot talk of a fault it was an outside. and this raspy had a lot of big sound is quite in chanting. to add a safe tonight feels the are sixteen stands for the famous french lifestyle a bit eccentric but very likeable and easy going road bumps a lot of public the other sixteen suspension smoosh them right over too lazy to change gears you can go forty kilometers. per hour or faster inches third or fourth gear and the seats are as soft as a sofa. absolute comfort tapa suitable. overall a pretty relaxing right now. we are sixteen really lives up to reno's old cars for life slogan it can be customized according to every owner special wishes until this day renault has a reputation for building great family cars. but who knows if there is stuff reckons renault built the right car at the right time it was produced for fifteen years from the mid one nine hundred sixty s. until one nine hundred eighty s. an impressive record as the first midsize sedan hatchback with a large trunk lid and flexible interior it set the standard for midsize sedan us as such the are sixteen is a milestone an automotive engineering and maya style the automobile shifted. overall one point eight million are sixteen's were built but very few models are still in good condition today owners took renault's slogan quite literally and drove their cars hard if you are sixteen's were sent in for repairs or to the car wash as a result many gradually wore out over time.

bought. the mazda three enters its next generation. and porsche rolls out a new version of its kind and. it's so world premiere at porsche instead gart the german sports car maker is celebrating the newest member of his family. and cooper was so much pomp and glamour because the new porsche crossover also do want to promise. guides it's very emotional a car definitely even more emotional than regular play and it was my absolute bits to the hype so much time in the car to to pull i done this one as something special and they would get it he says he likes the car especially the sloping roof line just as you want to expect from a porsche is not too surprising because most say this is in that with the g.l.a. it will pay. m.w. does the it six so i guess it said natural extension of course if at this to the line up. and naturally porsches new family member has very competitive engines that cayenne coupe a is being launched in two powerful versions one is a six cylinder two hundred fifty kilowatt turbo engine that allows it to spring from zero to one hundred kilometers per hour in six point zero seconds while the top model cayenne turbo coupe a comes with a four leader. and twin turbo charger its four hundred four kilowatts propellant from zero to one hundred and three point nine seconds. porsche marketing she of debt left home platen says the cayenne has become a little narrower has become a bit longer and wider from the rear so this version is twenty two inch wheeled rims which you would have a very strong road presence and appeals to customers who want to express themselves on the road and who really want to experience the porsche d.n.a. that's it you know and the. c.e.o. all over louis's this is an exciting evening because this is the company's first board's coupe a in the s.u.v. market porsche sees it as an ideal combination offering the features of the base model cayenne but with even sporty or design that is significantly more dynamic. seen from the front than differences from the normal kyin are hardly noticeable. it's only in the side view where its new personality can be seen passenger sit thirty millimeters lower than in the cayenne this means plenty of headroom despite the lowered silhouette because i am kooky as equipped with a panoramic glass roof and standard. optional eocene here there is also a carbon roof. says the launch of the first cayenne in two thousand and two nearly nine. a hundred thousand have been built this success and customers desire for a more emotional kyin influence the development of the cayenne cooper a its once pure sports car image has given way to a more striking appearance especially for the s.u.v. sector even so it's a look porsche thinks kyin fans will like. we are at a design fair in the western german city of cologne but among the furniture makers there's a surprising exhibitor car maker mustang it's showing off the new design of the fourth generation must of three along with new technology must is emphasizing its use of high quality materials. it certainly looks modernise forty but to drive it will have to go elsewhere. like portugal's coastal highway it's the new mosque the three has been redesigned from the inside out and since atop a new power train it's also the first production car in the world to have an engine option that combines the principles of gasoline and diesel combustion the sky active x. ignites gasoline through high compression like a diesel musta says that makes him very efficient and responsive current history man to washington for says the mazda three s handling can definitely keep up with its sporty exterior as good as it's taking curves it's also good on the gas or but he would have liked at least the option of a slightly larger engine with one hundred eighty kilowatts or more but for now unfortunately no such engine exists. at the front a large radiator grille is the dominant design element of the new mazda three the chrome trim is. more subtle than on its predecessor curved surfaces are meant to reflect the environment in different ways and ensure the harmonious appearance of the vehicle. in the hatchback the massive sea pillar that leads into the flattened rear is what catches the eye yeah that's the guy i know as a fan of the design and proportions of the mazda three he says the other vehicles in the segment like the out eight three and the v.w. golf just can't keep up. with. mazda also knows how to design a classy interior forward visibility has been improved by optimizing the a pillar shape inside most buttons have been done away with and overall the new must a looks very tightly the japanese maker aims to bring a sense of calm to the vehicle through the use of lines the driver is meant to be the center of attention. best design it's nice to model a says the design isn't just really great outside but also insight here with these curved lines everything is geared towards the driver and the quality of the work is really very high when you sit here and you feel right at home that's probably how he'd best describe it which is what i'm best at and this is all that's in keeping with mazda's design philosophy. or driver and car as one he thinks this is absolutely true on the mazda three full too often what's. the most a three is also technologically quite advanced we're testing it with the eighty five kilowatt four cylinder one point eight leader sky active d. engine with a sick speed manual transmission it accelerates from zero to one hundred kilometers per hour in ten point three seconds top speed is one hundred ninety four kilometers per hour mazda claims fuel consumption of just four point two leaders of diesel per one hundred kilometers our test card. concert around thirty one thousand euros in germany. is the man i was overall impression is that the most of three is a really great car that doesn't have any faults it drives well it looks good and it's also well built the only thing he would like to have seen would be the option of a bigger engine maybe a two point five liter petrol engine in the order of one hundred eighty kilowatts that would even give cars like to go out as three or are as free or run for their money it wouldn't be a problem to add an engine like that but without one it's not an alternative to those cars if the. law. were sadie's has unveiled its new am sheet a thirty five format make it comes with a seven stage two a clutch transmission and am cheap performance four wheel drive. this engine variant has two hundred twenty five kilowatts which propels it from zero to one hundred kilometers per hour in four point eight seconds the price has not yet been published but it should be just under fifty thousand euros. and b.m.w. has revealed its eagerly anticipated to seven series particularly noticeable as the comprehensively redesigned vehicle front end with a trademark grille about forty percent bigger seven series will also be available as a plug in hybrid model. if you sent the driving experience which from the seven forty five to sport a total system power of two hundred ninety kilowatts is available in electric mode it has a total range of just fifty eight kilometers this to ten lecturing. car can be had for about one hundred thousand euros in germany. audi's upper mid level eighty six seven station wagon is dynamic practical for everyday use and great for long distance commutes we took the latest generation first spin our version is the forty ninth with an entry level one hundred fifty kilo one four cylinder diesel engine. at the. given this new incarnation a dynamic new look with bribes surfaces sharp lines and short overhangs l.e.d. headlights or standard matrix l.e.d. lights with an adaptive height be optional. the interior is very up to date the digital dash owes all the information the driver needs. and there are two further displays but no buttons all drive and comfort modes are selected via touch pad. the card comes with a seven speed as trying to do a kludge transmission. this week stationwagon is almost five meters long from the side the car's trampas oil windows are clearly visible and thanks to its three meter wheel base there's lots and lots of space. inside for passengers. i'd have thought of a car tester in his pay three says the new audi avant has a sloping roof and slanted rear window and that despite these features outings engineers still manage to keep the vehicles cargo volume as it was before now but from. the trunk will fit at least five hundred sixty five liters of luggage and a maximum of one thousand six hundred eighty leaders to keep everything in place the audi comes with food rails as standard there's a natural and additional storage options plus the back bench can easily be folded down from the rear. there's plenty of tech to enhance this dynamic ride it has new ultra precise steering giving the driver perfect control for different types of suspension are on offer to. the ones he misses out in standard progressive steering an optional all wheel steering work together really well giving the car a number that you'd never expect from a five meters station wagon one of the business. even though the forty t.b.i. is the least powerful option available for the a six it's still more than enough for a sporty feel a one hundred fifty kilowatt engine delivers a maximum of four hundred meters of torque at just one thousand seven hundred fifty r.p.m. visit only makes the dash from zero to one hundred kilometers per hour and eight point three seconds. depending on which trim line you get the central driver assistance controller one process data from one to five radar sensors six cameras twelve ultrasonic sensors and one laser scanner. ennis says she was surprised by the predictive the fish and sea assisted which makes the gas pedal vibrate when the system notices you've reached the maximum speed limit or when you're sat nav shows you'll be driving into an area where you need to slow down enough says the car tells you to take your foot off the gas stop accelerating and saying fuel. costs. but these electronic assistance systems are not just designed to cut back on fuel they make driving safer as well but one thing in a system produces a thermal image of the surroundings highlighting the contours of protests three ins and cyclists the technology also detects wild animals and force so the collisions can be prevented. and. then that plane is says that all this talk of a night vision reminds her of how great this out he looks in the dark inside you can adjust the ambient lighting to a color of your choice and even pick different colors for different areas and surfaces this lets you customize your car's interior illumination thanks i'll still try that. thirty different colors are there to choose from but unfortunately like with all optional tech features that make this car even nicer and more fun it comes at a price when it comes to fancy interior lighting you need to shell out an extra five hundred seventy europe's but for that you get a really cool look you can even illuminate the doorsill panels and seat belt buckles. the audi as you know says the only a six of audience a sporting field thanks to a range of new tech features she thinks it's great fun to drive and she loves the modern and fresh design enos also appreciates the interior lighting which sets it apart from other station wagons and gives it a certain verb and playfulness. nice to look at fast and expensive it's almost a rule for sports cars but subaru b r z jointly develop when toyota aims to break it. it's been hard to start on the left stick with snapping sports who pays but the problem is that they are usually very expensive and therefore out of his range that's why he's testing the subaru b.r.c. today it can be had for less than forty thousand euro's with a two liter one hundred forty seven kilowatt boxer engine and rear wheel drive he wants to see if the b.r.c. has really earned the title of sports car. out of miami or manual for b r z fans there is a clear favorite the g.t. is available with a six speed automatic transmission but most go for the six speed manual. and that's what ronnie says the stick shift is a much better fit for the sports to play and the vast majority are sold with one you have to put in the effort yourself and is up to you how much fun you want to have. those close ratios and smooth shifting it's child's play to navigate quickly through the gears and it's easy on the pocket book coming out at one thousand five hundred euros less than the automatic transmission but when it comes to the engine there's no choice. that's why did ronnie says the two liter box there is an engine that absolutely wants to be revved because it only achieves its full torque of two hundred five newton meters at six thousand four hundred r.p.m. that means not much happens below that and you don't really notice the one hundred forty seven kilowatts the engine puts out until it's really turning. back. one against going it does what it's supposed to. when it's comfortably growing box here and you sound you can have a lot of fun but it comes at a cost in fuel consumption the manufacturers claims of eight point six liters per one hundred kilometers are something of a cheerful illusion a car manages the sprint from zero to one hundred kilometers per hour in seven point six seconds in germany the version we're testing with the optional interior equipment the b r z e sports plus costs at least thirty five thousand euros. and sporty appearance doesn't oversell as keep abilities and the l.e.d. lights look positively evil. the low down architecture displays typical coupe a proportions and all the lines eventually lead to a large rear spoiler. at the rear attention is drawn down from the spoiler into a generously sized tailpipes. the interior is reduced to the bare minimum but still looks up to date. for. the leather seats with the embroidery on all kind of tarik keep occupants where they belong in fantasy corners. ronnie says the b r z focuses on the pure were driving experience in contrast to other cars which are full of assistance systems that g.t. as almost none. here is can also get themselves a b r z sport without the flaps and it's me that saves another two thousand euros by doing without the leather and i'll come tarik and the heated seats. my thoughts it's the summing up ronnie says the super albie are zia's precise like a sharp sushi knife he thinks that to leader boxer engine could use a bit more power but that's not essential because the subaru b.r.c. wasn't built the said speed records on the highway but the adult corners with composure and so called. the b.r.c. is a sports goof a that emphasizes driving pleasure along with a growing box or sound and the good price performance ratio it also offers an exotic flair for german roads. the formula the racing series has been around since two thousand and fourteen and now there is the jaguar i paced intro for the motor racing series as well this year's event brings together eight international teams competing in different i pace motors ford vehicles team germany is led by christian do or. die for this in michigan says this is a production car which makes this something of a stock car race the first of its kind that's why for them this racing series is all about innovation he says this creates the perfect foundation to learn about and advance a mobility technology. and that's why the e trophy series exists and is held around the world along with a formula eat as i go and say you don't even dare take it on to form a reply. team germany's driver is twenty seven year old celia montana from france she says the racers are unique. but it is the basis of friends a miss the ends and saves is. that there is nothing. if you just have the steering wheel and your legs and concentrate on yourself that you have the noise of the thigh is about the same as the first jen says sealy is a young eileen talented driver who will benefit a lot from this experience race to the victory of. the team have brought in formula one driver and commentator christiane donna to coach celia. mentality racing veteran says that drivers need to be extremely focused when steering their vehicles through corners that's why he's convinced the race will be a great eye opening experience for sealy if. he's happy she's part of the team to see if you can also afford us of those. as successful race team needs a well prepared driver just as much as a top notch gunner. formulate east season will kick off in the saudi capital. the two kilometer long race track has a few tricky and tight corners which is why drivers like celia mcdonough most familiarize themselves with the before hand. the narrow track is a for minimal challenge for formulate the racers and eyepiece vehicles alike. and christian walk along the track by foot to get a feel for it and prepare for the most difficult parts. and says this is a fantastic course a typical street circuit he says it's not a wide open race track in fact quite narrow with walls on either side which makes it harder to get a sense of orientation so he says that i. makes everything look alike and also points out so-called elevation changes that make things even more challenging overall he thinks the course is not easy this is see here listening to also have also. then the vehicle is ready for the race all crucial ports are checked and the car is fully charged. sealy advancers special overall which protects your in case her vehicle catches fire this is a big moment for. those sprays posts i face to face for the race as well it's when he gets to see all this people having an interest in lots of sport and so for the first time here inside yet. one by one the racers passed through the pit lane entry and take up their positions because of heavy rain there was no qualifying session so positions are based on a training session instead celia will be starting from tenth place. and their off simon evans from new zealand who started from pole position is the first to reach the finish line after the sixteenth around the narrow windy racetrack is extremely demanding. celia comes in eleventh place which is no problem because there will be nine more races until july so she has plenty of opportunities to improve. us kids i mean my best take. the next race will take place on a. thirteenth in rome cars will speed through the eternal

from nature's example how bad plants and insects can produce agriculture. the science behind medicinal plants researchers are unlocking leonsis. but first spiders and their potential role in medicine there's so could save lives. mother nature is a master of invention science can learn a lot from the incredible materials around us like bamboo it's light flexible and still extremely sturdy because of the knots along the stem. cassopolis silk is another it warms up in the cold and cools down in the heat nature spins out all kinds of fascinating materials some could even be used to heal us. every year nearly three hundred thousand people have a heart attack in germany alone many of those who survived face dealing with a weakened heart for the rest of their life. that's because the heart muscle tissue damaged in an attack contra regenerate scar tissue forms which affects the hearts ability to pump. but this might be about to change thanks to spiders they could help millions of people regain a strong and healthy heart. find their path the spiders are simply amazing when it comes to producing materials they are masters at manufacturing remarkable fibers. it's the spider silk that has scientists excited it's made up mainly of proteins and it's a biological model a strand maybe two thousands of a millimeter wide yet it's tougher and stronger than any other known fiber. it's possible to milk spiders to. the material is being used more and more in the field of medicine for example the dressing. used inside our bodies. the most exciting aspect of these fibers is that they are invisible to the body so they can be used as a bio shield in stealth mode anything you wrap and so is no longer regarded as a foreign substance by the body this is a great achievement we can avoid triggering any reaction on the part of the body to the surface of so. ideal as a scaffolding material. that the university and. natural spider to grow heart muscle cells. microscope you can see individual cells contracting rhythmically. there is a downside natural. insufficient quantity. the problem was we couldn't produce. cells of the same quality or in sufficient quantities so we abandon the project because we thought we could never implemented in humans. but in the meantime thomas scheiber over in by a god was working on a possible solution to the problem artificial spider silk. the bank was we had one advantage before us twenty years of research had failed so we knew what not to do. after many years of work scheibel foreshock a way to engineer spider silk protein. good health. to achieve this he first had to decipher the d.n.a. of the spider then he identified the blueprint of a certain silk protein and translated it into the language of the bacteria and then planted these genes into the genome of the bacteria which could then produce the valuable silk protein. that was the plan and it worked. right now large amounts of the spider silk protein can be produced in so-called for mentors. after several rounds of purification and processing the protein is reduced to a white powder this powder can vent be processed as needed in huge quantities. we produce tons of silk protein in one hundred twenty thousand leader bioreactors it is in fiction anymore it's already in reality. the protein is being tested as a coating on breast implants to improve bio compatibility and decrease the chance of an adverse response. it's probably also well suited as a coating for artificial heart valves. sprayed on as a fin film the silk protein would make the foreign parts almost invisible to the body. and the synthetic protein looks like a fantastic resource for felix angle in his quest to grow new heart muscle cells as a gel it can be used in three d. printing. three d. technology is available we all know we can print non-living matter and now we're seeing it's possible to print a living matter as well. perhaps one day we might be able to print heart muscle blood vessel and connective tissue cells in just the right combination . for now the initial experiments show that heart muscle cells produced in this way can form a structure and beat synchronously for several weeks. in the future it might be possible to apply such engineer tissue to damaged areas of the heart and give it new strength. but the prospect of replacing and renewing heart muscle in humans is still quite distant the individual components of the printed heart tissue would have to grow together and form a single well formed unit and the implanted to she would have to be able to beat in sync with the recipient's heart nevertheless there is growing confidence that this goal will eventually be achieved with the help of high tech spider silk. it seems there's no end to nature's curative powers have you ever thought of metals as medicine. how about ginger as a natural antibiotic. all sage to treat a sore throat. they say is i'm a to see little treasure trove. there's still so much left to discover. it's knowledge dating back thousands of years the healing affects of plants and hopes knowledge that was of great importance in the middle ages and then to some extent forgotten. but many scientists are now developing a curiosity for these plants and medical practitioners are rediscovering their healing powers. to be marable remedies are often underestimated they shopwoman conventional medicine sometimes they're the first choice. where in town or snare frankfurt with interest from put karma she's looking for hopes for medicinal tease today she mostly wants young nettles and birch and black briefs. and some independents and nettles and birch leaves because they flush out the urinary system . and black berry leaves have an anti inflammatory effect in the mouth want to use all three to make an herbal blend quite and it's like a home remedy i've holds up with you can. also heard it at frankfurt's paghman garten botanical gardens she knows the potential of plants to protect themselves against pests and pathogens they often contain oils bitter substances and absolutes that kill germs. like willows along with many other active ingredients that contain salicylic acid compounds at the end of the nineteenth century chemists developed these substances in two thousand of the most. fever and pain relief medications. aspirin. there are more than seven hundred plants in germany known to have medicinal effect a new ones are discovered around the world all the time. research under this hansel is trying to unlock more secrets from the plant world he's investigating marshmallow root and cats whiskas which contain substances that could help really coughs and urine every tract infections. the research is job is to develop new drugs and improve the ones that are already available. that's the future the problem is the sheer multitude of substances in these magician all plants often we know the plant has an effect but many times we don't know which of the countless substances is responsible that's what our research is about cracking lish code so we can develop more effective medications we're. going to come and we're going to put. red sage is also an intriguing plant it's known to have a wound healing effect but there are over fifty attentional active ingredients so which one is responsible for healing when. researches are trying to find the same human skin cell cultures they treat them each with just one isolated substance from the sage plant. the question is does the substance promote cell growth. because for a wing to heal new skin cells have to grow in that area. the song also tested a few days later it's a painstaking test but the results could be huge. it would be a design it would be such a great breakthrough to identify which substances have the most positive effect on wound healing especially for bedridden patients with wounds that are hard to treat hopefully our research will help us to develop new drugs. scientists haven't tested all the substances yet but they hope to find the active ingredient within a year old tape and to develop a drug from it. the research is further along for other medicinal plants. from the s m it's a clinic in western germany he treats patients every day with highly effective herbal drugs the clinic is one of six acute care clinics across the country that focus on complementary and alternative medicine half of all patients at the clinic receive it usually alongside conventional medicine. for a severe cough for example but also to fight urinary tract infections and chronic gastrointestinal diseases or to lower cholesterol levels. the clinic uses more than fifty plant based medicines in the internal medicine department alone and house them so fifteen years. of supplementing conventional medicine with herbal remedies can offer big results. like for nonspecific back pain and i am and many people suffer from. visual unspecific back pain can be greatly helped by using herbal medicine because it's the biggest advantage of these herbal drugs is that they often cause fewer side effects significantly fewer herbal medicine also plays a major role in treating respiratory diseases it can alleviate the symptoms which means less coughing less pain in the limbs and faster healing and there's no conventional alternative to this herbal remedy that's on a par in terms of side effects. if you can use a lot so want to be fancy. of course it's always important to speak to a doctor about the cause of an illness and the treatment plan. self medicating with herbal remedies alone can be life threatening. it's a danger that isn't spawn put karma is aware of. even though the hope she collects are considered completely safe she's very careful and she knows when to seek medical attention. in this matter doesn't she. if i notice a slight infection in my bladder or kidneys i use these plans. done but i monitor myself carefully. if after two or three days there's no improvement i would definitely go to a doctor and have it checked out. but just bruise some of the black prelate she's collected straight away so that the active ingredients can infuse best. she tries the rest to make tea plans for later medicine cabinet scavenged from nature. even pesky weeds can help to heal us. we are still on facebook if there are any natural remedy use you swear by. but been ok yeah as upon tang is a fan of nettles because they can defend themselves and defend us. caprice it could work every year carnegie thinks i know vera is probably the best skin remedy she knows it has a powerful effect on the skin especially when it's combined with lemon juice and other natural products. and stim are just better gratis says ginger is the first thing he takes when he's ill and it's even better with a bit of honey and lemon. thanks for your comments. a seed becomes a seedling it grows its first leaves. and then flowers and eventually the fruit that feeds of its own and so the cycle begins again but plants change constantly depending on the time of day. josh upgrade from ghana sent in this photo with a question for us. why do flowers close at night and how do they do it. the flowers don't only move when the wind blows. or when you give them to your sweetheart. it all happens so slowly that the movement is best captured with time lapse photography. a rose bursts into bloom. wearing plants open and close their blossoms every day not all at night but at different times depending on their needs why is that they only pollinators to carry their pollen to other flowers and fertilize them. but it flowers all over and at the same time the competition for the piece or balancer of birds would be very great. crocuses do close their flowers at night the theory is that they do so to protect their pollen from the damp and the cold but how do they do it. at the sporty it's easy to see how it works that young people use their muscles and joints to make their dance moves. but flowers all they have to do is stand there to attract pollinators with their beautiful colors nectar and fragrance. but they do also have joints of a sword where the petals grow out of the stone. when the water pressure inside increases the bloom opens. when the pressure subsides the flower closes and takes or rest. it out what is red why are they buying do you have a science

energy carrier up tomorrow. but first we'll head to the final frontier. in the hollywood movie gravity exploiting satellite daybreak nights with a space ship with disastrous results. and accident that dramatic hasn't happened in real life but waste all this india is a growing problem since the first satellite was launched in one nine hundred fifty seven thousands more have followed many are now derelict but still circling earth along with other space junk that poses a danger also for the international space station. march twenty twelve four hundred kilometers above the earth's surface the crew aboard the i ask that suddenly receive an alert a red late conjunction something is on a possible collision course by controllers standing by here and to be fucking to. separate from an old satellite is bearing down on the station. mission control orders the crew to evacuate to a capsule that serves as an escape craft but then your. part of that sort of. the danger has passed this time a piece of the old cosmos two two five one a russian satellite missed the i assess by a few kilometers but the space station's crews strangest to close calls like this its windows and exterior walls bear the scars of less life threatening encounters space might be vast and launching the empty but in all cosmic neighborhood it's clogging up with lives out there right now called a million pieces of potentially dangerous space junk orbiting the planet. they include decommissioned satellites and even larger objects like components from spent rockets british sound designer nick ryan has developed an audio based system that identifies and localizes space junk most of the debris is tiny but the speed at which it's traveling makes it a force to be reckoned with. even the size of a flock of paint its. satellites or the international space station called for birds. it can cause. catastrophic damage it threatens our infrastructure and us because we were launching a century satellites and weather satellites and. the space debris is currently threatened. all of the search. and each impact has the potential to unleash a cascade as the amount of deadly grows so does the frequency of collisions between bits of junk this could eventually produce a nearly impenetrable cloud of it enveloping our planet if we want to continue sending up new rockets we need to start cleaning up this one has supplies for the i s s on board and also a small satellite called simply remove debris once it arrives the station's crew prepared the satellite for a special mission the first attempted clean up operation in outer space profess a good game or a yeti and his team at the start we space center in england are tracking the mission they designed the space junks we. look to be you to be able to speak to the future we really have to start the new clean up the i s s releases the removed debora a satellite that contains the suite of instruments that will be deployed to grab space junk. back on earth its systems worked well but things might go very differently up here. the first test begins the satellite releases a small box into space then seeks to recapture is the live video feed shows how the space dredger casts its nets. and they snare the mock dead really is captured in one fell swoop. the thing that struck me was i've i've been a fan of space for so many years but i've never seen anything like that i'm incredibly proud of this actually and you say realize this is a world first you know it's never ever been done before to be involved with something like that is really incredible. remove debris is set. to test a number of cleanup techniques in the months to come it's other equipment includes a retractable harpoon but what happens next will the satellite itself turn into a drifting chunk of space junk. to be a bit strange of a mission the technology for removing debris at the end the produces some of the results we're going to clean everything after this mission. the final experiment will be for the sweeper satellite to destroy itself that involves deploying a large drag sail that should cause its orbit to decay until it enters the atmosphere the satellite and its junk will burn up on re-entry. getting there but i think when you want to do this mission and for example remove some of the old southern us that are no longer working and then with your few dollars they're not really big the missions are going to be more expensive and clearly you have to convince all the various the calders to fund these kind of missions i think is a similar thing like with the autumn everybody agrees yes it's a good idea to try to please but who's going to be fun. and when the little litter picker does come to a fiery demise it'll look like any other shooting star as it takes its final plunge into the atmosphere. your screen goes dark no more tomorrow today your cell phones and sat nav don't work either without satellites every day life would be very different. there'd be no weather forecasts with repercussions for farmers one way or another we need satellites treated at oh i had a question about that. what's the usual distance between satellites. artificial satellites have been launched for more than sixty years and there are currently around two thousand of them orbiting the globe at differ. altitude still pending on the job day two. most are in low earth orbit or early go at altitudes of up to two thousand kilometers in the lower part of this region are satellites that monitor the earth the international space station also orbits in this. medium earth orbit or m.e.d.o. accommodates satellites at distances of two thousand to thirty five thousand kilometers from mars this region of space is frequented by navigation satellites. the next level at just under thirty six thousand kilometers is for satellites in geostationary orbit satellites here follow the direction of the earth's rotation they're typically used for telecommunications including global television broadcasts each geostationary satellite is assigned to a box around a hundred kilometers wide the distance to the next box is around five hundred kilometers. geostationary satellites have a habit of drifting out of orbit due to factors such as the earth's uneven gravity distribution. once a geostationary satellite reaches the end of its mission or has become redundant it can end up in a graveyard orbit this is located two to three hundred kilometers above its operational altitude. nonetheless the space junk that has accumulated over the decades remains a problem the problem is red white but only if you. do you have a science question that you've always wanted oncet with happy to help out send it to us as a video text ovoid smell if we answer it on the show we'll send you

w. t take it personally. with the wonderful people once to make the game so special. for all true for. more than for online. hello and welcome to tomorrow today the science show on d w. coming up. breastfeeding nursing doesn't just protect babies but mothers as well. motivating a teacher from germany on a nasa exhibition get his class on board. and inspiring at sixteen ballance less than ideal for pinning a few ocean now his project has been launched. but first let's take a detour into the animal kingdom everyone knows that elephants interact in complex ways in the head but other species have fascinating social lives as well. chickens for example can recognize over a hundred other birds in their flock and mice often grow up in social nests corporation brings many advantages especially for the weekend members of the group . when white stalks head to their winter quarters they fly together in large groups the ones who spend the summer on a lake constance on the swiss german border set off for spain some fly no farther. winter there are landfill sites after a trip of about nine hundred kilometers. others keep going and fly three and a half thousand kilometers to west africa how come what determines who goes where. biologist and they are flock is the first scientists do have researched this question in any depth and it had only meant undeserved no one had looked into it yet because it's really difficult to gather precise data on the behavior of groups of wild animals. stalks are quite quite you can't get close and stare at them and how can you observe in detail vast flocks on the way dr flock found a way in twenty four team she equipped sixty stalks with tracking devices and accelerometers and hope that some of these individuals would end up flying together . she's about to introduce us to one of those sixty birds who has a distinctive manner of flying. past their fire a bell. she's on the right when she demonstrates what flak finds interesting about her she's not a champion flyer the other one overtakes her with means. you have bare mirabelle authority mediocre a flying doesn't matter much in everyday life but when they migrated she struggled to keep up with the others that. mirabelle flaps her wings a lot while the other one coast smooth sailing. hypothesis was that the good flyers who travel fast head for africa and the slower ones who flop a lot only make it to spain. data from the accelerometers let the researchers know if the stalks are gliding or flapping. it takes a lot of energy to flap their wings gliding is pretty much effortless. but that's only an option where there are a thermal zob. bateese occurrence of rising warm air. all the birds have to do then is spread their wings and be carried upward in a wide spiral. the updraft becomes weaker the higher they go then a coast to the next flapping their wings as little as possible to conserve energy. but how do they find the thermals does each individual bird look for them or does a group follow the lead of specialist scouts who go exploring to find the updrafts . as luck would have it twenty seven of the sixty stalks being studied did form a group. flock and her colleague martin knowledge analyze the data from the tracking devices and determine that there are indeed leaders and followers within a group the leaders are martin blue they're experts at coasting and so high on the thermals among the followers is mirabelle she doesn't fly so high and she follows the leaders. as we were surprised that the slower birds at the rear make use of information provided by the ones at the front they watch how the leaders are flying so they can steer a better course through the thermals. these were groundbreaking research findings. to keep up with the leaders even the followers have to be quite fast. it's clear that not all stores have the same flying skills. some started practice at a very early age. prefer to lounge in their nests and where it turns out are more likely to be merely average performers on the wing like our poor mirabelle she has to work really hard to keep up. many posters have followers flap their wings a lot they expend a lot of energy meaning they have to work harder as they migrate so they can travel such a great distance they tend to stop in spain and go no further while the others carry on to africa africa. the experts on the long haul flight glide most of the way and expend as little energy doing that as if they were standing on their nests. the results of this research project are so rich that it's not possible to predict the destination of any given bird. because in the we've seen these behavioral strategies are so important that shortly after they take off we can already tell how far bird will go yes we only have to observe the first five minutes of flight to know if it will migrate to africa or only to spain. what about our friend mir about she called it a day in northern spain and winter on a landfill site. stalks returned to northern europe every year after chilling in the sunny cell phone line months is that perhaps at the root of the myth that stalks deliver babies another theory has it that stalks confuse them with their favorite food frogs really. mother would certainly disagree. they only ever see the best in their babies. and when nursing they produce the best possible nourishment milk that researchers have discovered is tailored to meet their child's needs. it's instinctual shortly after birth a baby will move towards its mother's breast in search of milk and latch on to her . ideally the first breastfeeding session should take place within an hour of delivering hormones are stimulated in response to the baby sucking that regulate the release of milk. is just five months old and is being exclusively breastfed by his mother ricardo. it's free it's always arrives at the right temperature it's always hygienic i always have it with me i can't forget it i'm fossil and the medical emotional aspects were really important to me and harvesting . breastfeeding has a lot of advantages not just for the baby but for the mother too it's nature's ingenious invention a mother's milk contains antibodies that help protect the baby against infection on a long term basis. biased as i think invest so much with an infant that has been exclusively breastfed even if it's for just three months has had as many middle ear infections as a baby that hasn't been breastfed and respiratory and gastrointestinal infections are much less common among breastfed babies than babies who aren't being breast. but is there something special about your own mother's breast milk human milk contains complex sugars called human milk oligosaccharides or h.m.o. those. and their composition differs from woman to woman and it changes over time. every mother creates these substances especially for her child there are hundreds of variations that also depend on the child's particular situation in life. and they protect the child from an infection by the bacteria and its own intestines. most bacteria and other germs can't cross the barrier of the intestinal wall themselves but need to be transferred by a receptor. these human all go sucker rides form a kind of protective wall and we believe that when a baby is sick the antibodies in the mother's milk change. it's not entirely clear what the signaling pathways are this but we do know the immune composition of the breast no adjusts and responds. the nutritional composition of breast milk is also ideally adapted to the baby's needs as ricardo herself has experienced. sometimes the baby is just thirsty and breastmilk starts off being thinner more thirst quenching and with fewer found but when the baby is hungry they stay on longer for the milk that contains more facts and there's strong evidence that it's not just babies who benefit from breastfeeding. mentioned that many people don't realize that the mother also profits for example women who have breastfed have a reduced risk of getting breast cancer and ovarian cancer and type two diabetes is less common to. reduce risk of breast cancer why might that be. medical experts only discovered in recent years that breast milk contents themselves these cells can develop in particular ways in accordance with what the body needs little is known about how they might affect the baby. we know from test tube experiments that to myself for example are changed or killed by the stem cells that can be want to spread nationwide women who have breastfed are less likely to get breast cancer. and also why breast fed babies have lower rates of certain childhood cancers because. the hormone oxytocin helps the mother's womb shrink after childbirth and it curb stress levels but that doesn't mean breastfeeding is always easy. in fact they actually at the beginning it was very difficult very painful it took me two months to get to a point where i felt comfortable with it. and that's a really nice feeling if i find it physically very relaxing i can really let go. so i'm kind. as well as having a positive psychological effect on the mother towson is widely dubbed the bonding hormone because it strengthens emotional ties between mother and child. some studies suggest that breast milk might help reduce the risk of a child becoming overweight also later in life. these are breastfed babies learn how to determine for themselves when they're full and there's a link to the leptin that regulates upper targets later in life that seems to me and the hormone leptin is contained in breast milk. carton darwell look pretty satisfied with their milk. from ghana. which my question is why are there some children resemble. the. order for them sometimes to be taken. it. costs all the time not to go to somebody you know it be. quite a question is. why is this. why do some children look like their parents and others don't. it used to be said that babies resemble their fathers scientists thought it had an evolutionary explanation that it was nature's way of confirming paternity and encouraging fathers to take care of their own children. but the latest research shows that babies don't necessarily resemble their fathers or their mothers for that matter. they do use the world over look more like each other instead nature is made sure they look adorable. guys. and. that's how babies ensure a ready supply of adult caregivers. they're so cute even a stranger well cared for them if something happens to their parents. and what happens when children are adults sons tend to look more like their fathers sons daughters their mothers that's due to the effect of sex hormones. what about specific features like eye color. well if the father's eyes are brown and the mother is blue their children's eyes will probably be brown because brown eyes is a dominant trait. but sometimes children don't resemble their parents much at all in the mix of the mothers and the fathers genes has millions of possible combinations. of nature enjoys variety so many babies resemble no one in particular only. themselves. if outlet is read write. anything you need to. do you have
