a virus spread. why do we parent and when we'll. introduce through the techniques and weekly radio program. if you would like any information on the crown of virus or any other science topic you should really check out our podcast you can get it wherever you go your podcast you can also find us at. the findings suggest that the laboratory incidents i put disease. he's extremely unlikely and. to explain the introduction of the virus into the human population. this seems to be the consensus off to a controversial joint investigation. into the origin of corona virus by the w.h.o.

and chinese government in blue hunt so where did the virus come from the prevalent theory is that the sars scotu virus is this so knows this that it jumped from animals to humans either from close contact with these creatures or the hunting of exotic wildlife so case closed not quite questions remain. indeed welcome to the night in special i'm monica jones in berlin nice took a year for china to allow an international investigation into the origin of the corona barrus and then only in a joint mission with chinese experts is beijing trying to hide something that wouldn't be the 1st time that china's handling of exotic animals led to the birth of a deadly virus. wild animals in cages many of them injured and weak it's filthy and cramped and the animals are in close contact with humans. the corona virus may

have started to spread in an animal market like this is the perfect breeding ground for new diseases. markets like this provide an opportunity for pathogens to make the leap from one species to another. in the process the pathogen can develop characteristics that make it easier to spread to a 3rd species in this case to humans. experts have long been warning that the trade in wild animals could be a ticking time bomb more than 2 thirds of infectious diseases that affect humans originated wildlife those include deadly diseases such as the ebola virus sars and hiv aids scientists call such diseases zoonotic because they originate in animals. who are not of diseases can be dangerous because the pathogen can develop new capabilities and its new host the new host has no immunity so infection can often lead to serious disease. the coronavirus pandemic has thrust these wild animal

markets into the spotlight around the world many are calling for a total bound. the animals are sold not just for food for private households some species assigned to make traditional medicines or aphrodesiac others and pricey delicacies on restaurant menus animal protection activists like these in vietnam say that the only way to reduce the risk of pandemics is to ban the commercial trade in wild animals that have viruses don't really make a distinction. you know. a lot on the higher train chain they don't make that distinction which whether their trade is legal or illegal whether their training is for bush meat for of so and for medicine or as exotic pets activists agree the desire for an exotic patas part of the problem

there's a flourishing illegal online trade in them especially involving reptiles. but wild mammals are also sold online illegally they pose the highest whisper transmitting viruses to humans china has now temporarily suspended the trade and consumption of wild animals but as long as the worldwide market exists the threats of new emerging viruses will continue. to professor fabienne linda you've just seen him in this report he supported the investigation into the origin of the corona virus and he joins us now good to have you with us a project group leader of epidemiology of highly pathogenic micro-organisms of the robot coffee institute here in berlin what was your role in. well i was asked to join the team as an expert on the not easy eases so i have the technical expertise we are looking since many years for the source of human disease

in wildlife normally mainly in the tropics in african context so is it a given though after this joint mission looking into the origin of the corona virus is it a given now that the virus has actually been transmitted from animal to human and did all of that happen in china. well i think everybody would agree that given that the virus comes from an animal to mentally infected humans because we didn't know it from the human population before so that's that's clear the question is now which species exactly were involved. and how did the transmission happen where is pressed let's kind of it in that context of that office the holes on the agenda and those questions you just raised do we know the onsen now which species and how you know we have very little evidence at the moment which species are involved the only thing we know is that the closest relatives of the origin of one

of this to if the virus is found in certain bat species in cells east asia or so that's a suspicious range of species to look at and a suspicious region to look at as an elf but the only other data not reading leading to to a very good process is at the moment i still have to ask you that question though i mean because there is this theory that the virus came from a lab even though an animal in the lab presumably can this theory now be ruled out oh are they still question marks. so the theory is extremely difficult to compete rule out. because technically that's a very big challenge haul ever the likelihood that this has happened is extremely low if you consider how intensive we have contacts between wildlife and humans into media tools farm wildlife and humans this simply seems to be the least likely

scenario so i think we should investigate this in the research of the most likely ones and then later we may still come back to the other processes all right then let's stick to the transmission from animal to human and i mean even here in germany of course we do have virus spillover from from rodents to human for example every year so when does the transformation from the virus from animal to human become a real problem like the one we're now seeing with this pandemic. so as you say that frequent transmissions and it's not only boris's and if you think about. colon functions like in the food industry that's frequently a problem right so and that's a severe problem we have so the question sometimes terms into an epidemic or pandemic virus really depends on the property of the virus in the 1st place so is it something easily transmissible from human to human so for example

hunter viruses that you find also in germany transmitted from rooms to humans are not well transmitted between humans so they are simply lucky that the virus doesn't have the property like this on star as has you know so that's one of the important factors or the most important factors i would say lastly i mean why does it actually matter to know the origin of the virus i mean what it actually help us fight the current pandemic. it doesn't help divide the current pandemic but it helps to reduce the risk of future pandemics to happen and these kinds of pandemics have happened since many many years old a time think about age and he seemed about even measles come from an animal origin or so we will continue seeing these kinds of things so you can only solve the problem if you have understood for only 40 and then you can take the right contemn measures to reduce the risk of the events so this is what we need and we need that from all the breaks happening not only the very prestigious one as this one but we

need to understand the mechanisms because then we can do something to reduce the risk all right and there's still a lot to learn from the current source code to virus i understand bobby and then doubts project group leader of epidemiology of highly pathogenic micro-organisms at the robert capa institute thank you so much for your time. now from the virus to the solution vaccines time for question sent over to derek williams. vaccines be as effective against new variants of sars cove 2 as they were against the old one the hope is they will be the fear is they won't be there's been a lot of conflicting information turned valid on this topic already and with around you know a dozen different vaccines approved in various parts of the world at the moment and and new variants being identified same lee every day that mountain of conflicting

information just grows and grows the most striking reports so far that a new variant was was steamrolling over a vaccine came from south africa the small study it was based on left some open questions but it did indicate pretty strongly that as for the seneca vaccine didn't do a very good job of preventing mild or moderate disease caused by a variant in wide circulation in the country that evidence was enough to prompt the south african government to decide to start using the johnson and johnson vaccine on its health workers instead. so yes there are signs that new variance could have an impact on effectiveness and some back scenes but i'd like to add my

voice to a growing chorus that includes many researchers who worry that all the hyped up reporting on an variants and studies involving them is actually counterproductive not only because it frightens people but that it does so most of the time for no good reason the vaccines currently approved are based on a range of different platforms that stimulate the immune system in different ways some of them might prove less effective against newbury and others more so the thing is even when the virus changes which it will continue to do we can respond like the government in south africa by switching tracks we now also have the technical ability to tweak some vaccines quickly to respond to mutations in the virus so i at least have come to a decision not to let any fears about new variants keep me up at night.

derrick williams there in speaking of switching tracks the german government has just approved astra zeneca for people over the age of 65 the vaccine from the british swedish pharmaceutical has so far been only deemed safe for people under 65 the government hopes the new rule will help speed up vaccination here in germany. and that's it for the day from me and the team here in berlin thanks for keeping us company. the general trend in. the. predominantly economy. companies are making billions in revenue from the new technologies and the trend is on the rise. but how harmless will they be in the long run to consumers

and be an argument. made in germany. on d w. to the point the strong opinions clear position the international perspective says. quote francis is visiting war torn iraq the country's it is the cradle of christianity if brings with him a message of peace and reconciliation but who'll be listening in iraq with the christian population has been decimated to find out also the point to the point. in 60 minutes on t.w. . different. bylines of. your society.

women differently. what do they do with their passwords. and how sustainable is this culture. clings of durango starts marching on t.w. . there's a tendency to think that a bigger is better consider diamonds houses cars but it's often the little things that really makes a difference some so small you can't even see them from nanotechnology to micro homes and amateur traders they're all making a splash and demonstrating that size is actually relative when small is big that's

our topic today welcome to made want to get jones in berlin it's good to have you with us now back in grammar school i had a teacher. who wasn't actually told he was a powerhouse he used to say i'm not small i'm concentrated his lessons were very intense and successful even i had excellent grades in mass and physics small and concentrated could also apply to nano particles they are found in lots of modern everyday products to make things water repellent for example but what do we actually know about those super tiny nano particles and their interplay with our lives many other smith reports. this is sung to the ocean with now particulates. what does the nanotechnology have to do with me. i was trying to shoe polish

containing nano particles it was supposed to make the polish absorb into the shoe better it didn't help that much but it seems there is something new for me after all in the wonderful world of minuscule artificial particles. i have a broken molar which has to be replaced with a dental implant until now there was a risk that bacteria would attack the implant and it would have to come out again but the none of coaching of silver can protect against bacteria in the future. precautionary tip from german company arias has developed a coating for dental implants. detainees in big. technical development takes a few years if it happens at all. and then there's the certification process to prove the whole thing is safe. that often takes years at least a decade. because the hurdles are high. they want to avoid putting the

consumer at risk in any way and that's a big challenge for a small company like ours. the stringent demands are also slowing innovation. as you can see 1st and as any whenever i contact the medical equipment makers 9 out of 10 of them say they don't want to pursue it because the regulations have become stricter or they have become too vague leaving no planning certainty. that no articles can also be found in many foods such as chewing gum and baking powder where they make the whites appear even brighter it's basically just a coloring effect. critics are worried about the use of tiny particles in food though. we know that certain nanomaterials cause inflammatory reactions in the gastrointestinal tract that's a precursor to cancer and the kind of thing we must prevent so why is it that something like that gets

a license when it can cause inflammatory reactions. the reasoning was there is a labeling requirement for nanomaterials in food but you won't see any foods labeled contains nano products that's because we're still arguing with the various industry associations about whether it still has to be declared as such because they say they haven't used it as a nanomaterial but there are always some nano components in the product itself. ok honestly i go. through doing. nanotechnology is uncharted territory rich in potential. i would like it either but then not everything that's useful is also edible so that shouldn't be a criterion when deciding whether new technology is worthwhile and when it comes to manage technology there's still so much to explore in recent decades scientists and

engineers have learned to make and manipulate nano particles and nano structures and deploy them and products and processes the range of applications is enormous and expanding fast see for yourself. small smaller smallest nanotechnology. a human head has a diameter of 50000 nanometers one nanometer is just 150000 of the diameter of a hair. here's another way to visualize it one nanometer is 2 a meter what a hazelnut is to earth. nanostructures have fascinated scientists for decades now they're even able to make some of those structures themselves they can manipulate matter at the atomic and molecular level so that the matter takes on new properties. industry has discovered the virtues of

various nano particles many sunscreens now contain ones that block u.v. radiation. silicon nano particles are used in smart coatings that make fabrics water repellent that's a novel way to waterproof clothes and upholstery. super sticky glue tennis balls that keep their bounds and unbelievably tiny computer chips all thanks to nanotechnology. it's become big business sales of nanotechnology have been growing at an ever faster rate. than one estimate put the global market value in 2020 at 63000000000 euros. nanotechnology is said to revolutionize many sectors in the field of medicine research as intense and wide ranging. it's also contributing to environmental and climate protection. nano scientists even working on self healing materials

imagine a crack in an airplane wing that repairs itself with nano particles going where they're needed for now that still pie in the sky but perhaps for not much long. nanotechnology is really taking off. now severe lack of space has led to a shortage of fordable housing in many big cities try finding a flat in berlin a nightmare as a result some people are setting their sights on something smaller a tiny house unconventional lodgings are already popular with holiday makers in 2018 air b.n. b. so a roughly 125 percent increase in worldwide bookings over the previous year the figure for barnes was 110 percent and shepherd's huts came in at 93 percent plenty of people are also looking to downsize permanently so we met a successful tiny house builder in germany and an architect in hong kong says small homes are key to overcoming homelessness.

anika factor is a product design and has built herself the house of history. we live in a tiny house i live in a tiny house. i used to build movie which is quite different. when i left the film industry and travels for a while everything i needed was in my backpack i went to a tiny house is a lot like that everything you need fits into one room and there are lots of places to store stuff away from everything else multi-functional. she works for stefan. he started building tiny houses 5 years ago and now has one of the biggest manufacturers in germany. he builds foresee a year none of them larger than 25 square meters. first saw them in canada. i spent some time there and saw how they were

building micro houses though they weren't mobile homes on leos the idea really fascinated me. from. then the trend reach europe from north america we picked up on it relatively quickly and decided to build a prototype and see how it goes through bone off more important to almost. this starting price is 45000 euros for a house like this some customers want to live in this full time others just for holidays by the way you can't cram much stuff in here. many minutes many people have come to appreciate minimalism downsizing arleen living we know that because we see lots of people here who think that way. if the 1st time that if you're living in a small space is just one aspect of minimalism more generally it's about reducing your c o 2 footprint out i don't know i am part form to my minimalist most choosing to live

in 20 square metres rather than 60 square metres could be part of that it would have the type of woman behind so no further north tons of metal in hong kong for example 20 square means his is quite stand it and still very expensive lots of people very close quarters they can't afford more space james lewis an architect based in hong kong has designed microphones in segments of concrete water pipes he calls them open. so i came up with the idea on one day i was on my construction site and i saw some of these very large concrete wall of pipes being laid into the ground and i walked into one of them and they were big enough for me to go inside and suddenly i felt that this instant architecture this is like an instant shelter which with a bit of design and

a bit of creativity could be quickly made into a small house. he says these low cost units can help eradicate homelessness and ease the shortage of affordable housing $120.00 units are said to be built in hong kong this year more are to go up in canada laws says the world needs to rethink housing as the population source. homes will have to get smaller and. the cities are so. so expensive to live in space is so tough to get and so many people are chasing after that space so that you know wait the architecture we built it's no longer so affordable for people so maybe this idea will become necessary in some form in every urbanized area in the world because we realize that we cannot always just build iconic and expensive projects for

a symbol of our city we also need to really take care of people otherwise the people will really excel. hung congdon is only one of many cities where housing is very expensive and in short supply. stephan dyckman says the market for tiny houses is going to be here to. tell but if i for i think people have become more flexible nowadays they're not so bound just staying in one place with a lot of computing. well that's another reason for choosing the tranny house what i'm about is for the entire house dyckman plans to open a tiny house hotel once the pandemic is over that is the pint sized units are ready to go each one is different. i think our focus doesn't need to be convinced she's already a fan and says her tiny house gives her everything she needs. should be easy to keep clean moving on to the world of stock markets more and more amateur

investors are trying their luck these days and they're even sending some stock prices soaring but in this very risky business the stakes can be high here's my colleague to delay new with the lowdown on day trading. the beating heart of germany's financial industry the frankfurt stock exchange but it's a little work down even still trading has moved from stock exchange floors like these to our phones and laptops deals are done while waiting for a friend or for a coffee and by people like you and me even my mom's doing at amateur investors have flocked to stock markets like never before since the crown of iris endemic and while it has devastated many people's lives and jobs other people have found themselves with extra time and money during lockdowns and this record breaking rally we've seen in global markets has made many people already very rich. that's and p. 500 in the u.s. was up 16 percent and 2020 but that's nothing compared to this day trader favor at

tesla at more than 700 percent i've been covering stocks as a journalist for years but i'm ready to get out the sidelines and try my hand at being a pandemic do trader. 123 platform when a lot of people think about trading stocks their mind conjures up a scene like this thank you. and while you still can trade stocks by calling up a broker trading has increasingly gone digital setting up an account as easy as downloading and now there are dozens of free or low fi options out there to choose from step 2 choose your stocks. hard day traders make hundreds of transactions every day others like me have day jobs and only so much time for writing market swings so i have to make my investments count. oliver wrote as

a trader here in frankfurt he says we should all be trading stocks because ultra low interest rates mean more traditional investments like savings accounts no longer pay. there's no way really a turn or 2 of the stock investment when you look at the interest rates they are so low it's not possible to save money on the account or somewhere else so this is just without an eternity of therefore even the private people the private investor retail investors very interested in stocks even in germany which is not very popular on the on the stock side today is the 1st day of my experiment as a pandemic day trader what advice do you have for me as the new the from a professional like you. know 1st of all if you go to the stock exchange you have to be very disciplined and that's very important because you need to think about where you want to invest why you want to invest and then you have to be disciplined by saying this is where i'm going the prices where i get in and where i

will get out should i buy a tesla you shouldn't invest only intensely you can invest in tesla because i think there's a lot of things are going on but nevertheless you have to to to see to spread to a risk to divide your risk on certain certain pillars and to us that could be one of them but also other stocks have to be in your portfolio which is very important ok so oliver says i shouldn't. all my eggs in one basket i'll be buying a mix of company stocks and exchange traded funds or e.t.f. which are seen as a bit safer because they include a variety of stocks since i'm a journalist who cover stocks out be investing in the stimulation of my app which is a good way to try out a trading without putting your money on the line for the aspiring investors out there step 3 know your timing ok so let's see how it. i started out with 100 euros on day one telecom amazon and an e.t.f.

that tracks european banks markets went against me and i ended in the red. 'd states you want a little better thanks mostly to task which continued its relentless rally. 'd after 2 days i ended down a little more than 2 year olds. but it could have been worse trading is very risky even the most experienced wise and investors often find themselves caught out by market swings some studies have shown that around 80 percent of day traders end up losing money and some of these new platforms have been accused of manipulating investors and under playing the risks of trading. knowing how to time markets get buy when to sell is one of the hardest parts of investing many traders are eyeing this rally warily chilled by central bank stimulus markets climb higher and higher . really deeply concerned about the situation where were you as long as the simple

bearings are making the money so cheap. the longer the bubble can grow so i don't see i see of what will but i will see that the bubble explodes i see that the bubble we crow and grow and grow for certain time. as attorney i didn't strike it rich as a tea trader but it was just a simulation after all and i'll be keeping my day job. good idea for making a windfall on the market too profiting from wind itself germany won 65 percent of its energy share to come from renewables by 2030 and that's a tall order given that over the last 10 years the shares of wind power in germany's energy production only rose 19 percent from 6 to about $25.00 it will take many more super sized wind turbines to hit the bigger target but where do you put them we visit a wind farm under construction in northern germany. new

wind farms a cropping up across germany these technological marvels a taller than the world's highest church tower bigger is better and more powerful. germany's long term goal to become carbon neutral relies on harnessing the power of wind. down at the construction site workers are assembling tower segments the towers massive base is made out of solid concrete it's the only way to build that time i. began with the 1st prototype in 2010 since then we've built erected more than 2000 wind turbines we even built the world's tallest in 2017 with the hub height of 178 meters and blade tips that which more than 240 meters. 13 wind turbines are being built in the far west of the country nim and the energy they'll deliver will be put to good use is that he wants germany's last coal

powered plant shuts down in 2038. but the expansion of wind energy is not going fast enough in many parts of the country says me land in each he's managing director of the company that operates this wind farm. this project is special from the start it's had strong support from the local authority the district and local people even the city's utility companies are involved so everything gets done much faster in places where citizens initiatives say not in my backyard it can take a lot longer. banners like this one sign of local resistance some people in the region complain that wind turbines are a blot on the landscape that's part of why it can take 10 years for a project to be approved. this village is home to an active citizens

initiative. awning is already annoyed that her house is surrounded by wind turbines . now they'll be joined by more less than a kilometer away from her farm 5 months you can hear the wind turbines from a kilometer and a half away and you hear them turning and it's annoying that's your thought and if they're even closer when the sun comes out you'll be in the flickering shadow. but there are ways to get communities on board. had a good experience on this project he talked to locals before hand and offered them a share in the wind farms profits. this year my home is that's what they do is raise the capital for the project from local residents their sensually give us a loan and we give them back interest at a fixed rate that could be 5 percent maybe 6 percent that's quite

a lot compared to the interest rates banks offer nowadays and there's a lot of. very few. we asked the residents how they feel about the wind farm. i was amused i'm not bothered by it and i only see the turbines in the distance and . it doesn't bother me i think it's good because renewable energy has to come from somewhere. i do understand where the conservationists are coming from when they say it has a negative environmental impact. i work in a green job myself so i can relate. but it's good that we're working towards renewable energy and building goodbye to fossil fuels. your highness peter is a farmer in the region he least one of his fields to the wind park he also bought shares in the company and will soon receive annual dividends acceptance for acceptance on the ground improves when local people are included. they get

involved with a project and say this is our project benefits us all. we may bring you a bill energy will also. benefit from the project once the wind turbines go into operation. well they have local contacts also helps boost public acceptance and understanding. if all the older wind parks in germany were replaced with efficient ones like these the country could meet all its current electricity needs but not for long germany's electricity needs might soon double especially if electric vehicles replace gas and diesel powered ones. and building a wind farm like this is a major undertaking. a huge blades and most of the components arrive on heavy duty transporters.

the transporters are accompanied by escort vehicles the convoys top speed is 80 kilometers per hour navigating a load that's 80 meters long around a corner is a tricky operation a crew of 12 make sure. this blade was built in poland it's traveled a 1000 kilometers already. the rotor blades have grown over the years that's always been the big challenge 1st we said we'll have to stop at 45 meters then we thought we'd have to stop at 15 meters and now we have blades that are over 80 meters long. the turbine blade is a technological masterpiece and engineers are working to get even more out of them they're also trying to make the turbines more environmentally friendly and less

disruptive to people and animals in the vicinity. of turbines quieter we use what we call dinosaurs on the. slats that help reduce turbulence and reduce noise. to help protect the environment we have recorders which shut down. turbines when they register bats flying nearby on. shadow sensors so when the sun shines from a certain angle nearby buildings and houses aren't bothered by flickering shadows of the dark started up. this blade is being mounted on to the tower today when the wind park is completed in a few months it will deliver green power to 40000 households. but new wind farms will only succeed if the people who live nearby give them the green light. here at least they found a recipe to make it work. and that's all for this nano edition of
