siegfried and roy their shows up and featured dozens of wides tigers and lions long time partner roy horn died last year as a result of complications from co the 90 you're watching the w. news live from berlin ben facility is up next with but e.w. covert $900.00 special thanks to a company that. the fight against the coronavirus pandemic. has the rate of infection in developing what does the latest research say. information and contacts the coronavirus update 19. on t w. 2 children 2 continents. one giant problem and when you are in no mood to see

a picture you. little feet very thin layer if you count. how will climate change affect us and our children. learn more. dot com slash water. blood plasma is saving the lives of people with covert 19 but there isn't enough of it that's why scientists have been trying to recreate the antibodies it contains in the lap and they've done it. they've developed defensive proteins that can successfully fight off corona virus the us president was even treated with them. but these antibody drugs and in wide use even though they could make the difference between life and if. all sounds great

we still don't have definitive data but trials are set to get underway like so much in this crisis it's learning by doing and it's thanks to some brilliant minds from the world of science. this blood plasma can stop a coronavirus infection in its tracks the antibodies of recovered patients can be used to treat people with covered 19 it's already proven effective for patients including loot food she on point was at the start i was very sick my wife sent me here in an ambulance i spent 2 days in the normal ward but then they decided to send me to intensive care and i was just drained. yeah my. blue tooth condition became so severe that he was placed on a ventilator he was then the doctor how burned his team gave him plasma from a recovered patient at the end had the patient receive the plasma after his

risperidone condition and his lung function to tary aerated significantly within a day or 2 he stabilized and we were able to take away the breathing support. to get the plasma you need blood donors who have already survived covered 19 their blood has neutralizing antibodies that can render the corona virus harmless. the plasma is given to the patient through a transfusion then the antibodies within it get to work fighting the virus before the patient's immune system has produced enough defensive proteins of its own. the plasma clearly did the trick for lou true dutchy but the successes remain isolated cases and the general effectiveness has yet to be proven in studies over doctors say plasma therapy is helping the most severely ill patients. many

doctors would like to use plasma more often ideally giving it to patients in the early stages of the disease when it's likely to work best but the problem is there isn't enough of it. to realize that everyone who recovers from corona virus has a different amount of antibodies in their blood only those with a high level can be suitable donors. but can the antibodies be produced without the need for a donor that's exactly what research is in braunschweig are working on. this to contain an entire gene library so a collection of genetic material in acca lection we have 10000000000 different genes that's the entire repertoire of what our body has available to produce antibodies. to build. in this gene library the scientists found an antibody that works perfectly against sas code 2 in lab tests it completely

prevented the human cells from being attacked they were then able to reproduce the antibody based on its genetic blueprint and produce the 1st dose of their antibody drug. it has major advantages over the plasma therapy because it can be manufactured in large quantities and as a consistent quality with the right funding human trials of the teams drug could begin as soon as next month and the scientists work can begin to save lives. and let's talk to stefan jubal who featured in that report we just saw you holding up a chook to the camera what was in there. actually this very small vial contains literally the complete immune reaction of mankind in respect of antibodies so more than 100 people from all over the globe donated blood and be extracted from their blood the blueprints to build antibodies against almost

everything so more than 10000000000 different blueprints in form of genetic code for antibodies against different diseases are in this wild and my letter atory has now developed a technology to i did you fight one specific antibody which binds to sascoc 2 for example or 2 other viruses so this antibody can then neutralize a virus and can be used as a doctor to fight the disease and it's a molecule which is mate in our own body so it's not a chemical or not an artificial substance it's a molecule which is identical to the one which is in our body anyway if we get the infection can you briefly briefly let me in on the secret had how did you actually pinpoint that out of how many did you say 10000000000. how did you do that. it's a trick which i co-invented about 30 years ago together with some other people and

it's a. trick where we managed to connect the blueprint though the genetic information to the function which is the proteins in front of not all particles so we have 10000000000 different not all particles which can be then selected by a simple. experiment. for the binding itself and when you have the binding of the protein it has the genetic information inspect back and be done but get it back and isolate their own and get the antibodies so you've managed to produce antibodies otherwise only found in the blood plasma of covert survivors are they just as good though. well that has to be of course has to be shown in the clinical studies but in principle our antibody is derived from the blood of patients and performed in the plot. and performed in the

experiments we did in the preclinical studies very very effective and you knew it neutralized the antibody in the lungs and it 100 percent protect it. against infection so it's very efficient in respect of protecting against to what about these clinical studies of anybody therapies that show severe side effects like the overreaction of the immune system how can you prevent that this is a very important point and we thought of that since the beginning of the design of our own t. of our antibody and we managed actually to address this problem by changing the signal it part of the n.t. body a little bit by a logical means so that we completely avoid the simulation of this overreaction so in the training we expect not to see any of these overreactions which are seen

in the other antibodies and just tell me briefly do antibody treatments provide long term protection against the virus they provide immediate protection which is different from the back side but then they only last for about one to 3 months and have to be repeated but they can be given repeatedly standard thank you very much interesting stuff and congratulations on your work. and take a look at some of the other corona related stories making news preliminary results from a study show recovering from covert protects against infection for at least 5 months public health england tracked 20000 health care workers and found a previous infection provided 83 percent immunity similar to a vaccine. the world health organization is looking at introducing covert 19 vaccination passports for travelers some countries are already trying them critics call the passports discriminatory. and w.h.o. scientists are now in the chinese city of new plan to investigate the origins of

the pandemic the long delayed trip follows months of diplomatic wrangling beijing argues the virus may not have originated in the southwest as scientists a spate. of it out to our science correspondent derrick williams if you've got a question he's the e-mail feedback dot english at d.f.w. dot com type expert in the subject line or leave a comment on our you tube channel. if you get a 1st back scene shot made by one developer what happens if you a 2nd shot from a different developed. as the pandemic reaches a really critical stage in many countries in one of them britain health authorities have changed some rules on how they're going to vaccinate. one of them was this that for the 2nd shot in a 2 shot regime in some rare and exceptional circumstances for example if the individual concerned is got to be immediate high risk that's

a nadirs will be allowed to mix and match vaccines if they don't have any more of the product from the 1st shot so just to clarify there are 3 candidates currently approved for use in the u.k. from pfizer biotech from adana and from astra zeneca and they all require 2 shots of the same vaccine to work as well as trials demonstrated this decision means that if someone there gets the 1st shot say of the madonna vaccine when they come back for the 2nd one they could theoretically receive one made for example by astra zeneca if the authorities have run out of the madonna vaccine the thing is nobody yet knows exactly what kind of impact that could have because there have been no mix and match trials each manufacturer kiri doubt their own trials involving only 2

doses of their own product so the question of how interchangeable they are is really wide open one american professor told the new york times that in his view the british authorities in the current emergency were trying to guess their way out of the mess the british guidelines however call the move reasonable since in different ways. all 3 vaccines target the same area on the virus what's called the spike protein and experts in the u.k. think a 2nd dose of any other approved vaccine would be better than no 2nd dose at all and i'm to be honest i don't know enough about that scene science to make any confident predictions and opinions among those who do know enough are divided but i can say i think basing decisions like this on on reasonable assumptions rather than on hard data is risky and a lot of experts agree. and putting your

a priest i'm hopeless changed me to be fair listen to our podcast on the green. why subscribe to do you know where you books you meet your favorite writer seems i like to see myself as the kid sky in the strange grown up world. on you tube. and today is a very polarized world there are still some things we can safely say unite us like food we all have to eat but we're only that simple who sells it and for how much is a deeply disputed topic when it comes to food can cheap be good our focus this week on made. now here's something i've heard

a 1000000 times but have trouble taking to heart you get what you pay for meaning the more you spend on something the better it'll be but that doesn't stop me looking for a bargain and potentially regretting it later but some sellers will have you believe you don't have to compromise my county the german supermarket chain with thousands of stores all around the world my colleague chris down for save us went to find out how that could possibly be true. how the is one of the world's largest supermarket chains actually it's 2 chains and. they both pride themselves on that rock bottom prices and high quality product how does audi do it. it's 3 30 in the morning and all of compost is already at work he manages an aldi not distribution center as big as a football stadium. the company rarely lets t.v.

crews come to visit this is a rare exception. trucks will be loading here soon and everything has to go very fast it was the same yesterday afternoon and yesterday evening when the goods were assembled for distribution and will keep up the pace this morning to. front load his truck and sets off on the 1st of 3 round trips today his 1st stop is the closest 20 kilometers away. there are more than $10000.00 of these around the world. and they all get daily deliveries their stock rooms are small on purpose in order to keep down costs. it's now 6 am store manager and father john bussey 5 colleagues have to restock as much as a 3rd of the shell. every morning the store opens in just one hour. i just i

like to go to the gym when i have time but working here is fun and i automatically get lots of exercise. the staff tell me they get paid more than the average for the sector but the audi chain has come under criticism for its employees heavy workload and long hours. and how it gives a heads up aeration for the region in germany only stores report more revenue per square meter shop space than any other discount or. also roast its own coffee from their food started very early in the company's history it was probably hard to convince suppliers to sell coffee to what was then called the album they should accompany good coffee it's a really fun so they decided to produce their own coffee coffee is about and that's been very successful. for some well known brands don't want to be seen to have their goods sold at super low prices at discount supermarkets. to get around the

problem he sells a brand named goods under its own labels. this is where the story began in essence the 1st store its 2 founders opened is still known as number one. mother had already run her own small corner shop then in 1905 her 2 sons cottontail obliged opened their 1st supermarket. this used to be the standard look unadorned pretty basic these 2 staff members met one of the brothers the pioneers of no frills grocery retailing. they just lay about how and on the floor and then lot more pallets with cans of tuna or pineapples or peaches or whatever was available on the market at that time of year that are put off and they just pile them high. one price labels

cut open the front of the cardboard boxes and that was that. he came in and i wish i knew mr albert many many years ago he would do his shopping here every fortnight and he would always take the rejects the dented cans and sat 1. 100 going on until the old place came along no retailers sold goods out of piles of cardboard boxes at super low prices with a tiny profit margin per item all that coupled with low overheads and high efficiency was a recipe for success. carl until you ran id together overseeing its rapid growth until 1961 then the brothers parted ways each setting up his own company but those are very similar to you headed out not easy it 2 decades ago both companies started setting up shop in foreign markets between them they now have more than $10000.00 super markets around the world.

in recent years more attention has been paid to the design but the book is getting more sophisticated but that doesn't scare away the regulars. if i live nearby that's one reason then there's the range of goods and the prices you poison. some things i buy it other things i wouldn't buy it. because time by most things out the less they don't have something. i want to find out more about the cost of the modernization program i'm invited to an off the record chat at the headquarters of the not in essence the privately held company never reveals much about it in a workings and doesn't give me any numbers. what is public knowledge is that in 2018 it posted an operating loss in germany for the very 1st time reportedly because of high investment costs. legal has more branches the

competition and the pricing pressure of fierce. audi is famous for its weekly special offers popular products at extra low prices but that's not at the heart of its strategy. we're market leaders when it comes to pricing because our customers always pay the best price on all our items so ruthless top quality at the lowest possible price. has to rise of course other supermarkets and discount chains also your customers with great prices in germany the hottest price is probably over meat pork or chicken can end up cheaper than common or garden vegetables is that compatible with humane animal husbandry concern shoppers can scan q.r. codes to find out more about that meat processing plant the farms and the livestock . we aim for transparency customer should know under

what conditions animals are bred. we require our suppliers to abide by all the relevant regulations and we check up on them. and. we have a law. corporate responsibility department does regular audits of our suppliers you can do so you. know what it's good. corporate responsibility appears to have become important to know what. it says it receives and answers lots of questions from environmentalists. consumers are becoming more discerning and that's raising pressure on the retailer to show that it takes its responsibility seriously to ensure that cheap can also mean humane. play last year around 10000 farmers with 5000 tractors made their way from across germany to converge here in the center of berlin they came to protest the

government's new policies on the use of fertilizer now those regulations are meant to help protect the groundwater but german farmers say that will affect the harvest and they're furious our reporter karl went to see some of these farmers spoiler alert they're still angry. each of these combine harvesters cuts a 10 metre wide swathe through the fields of rapeseed for most of the year the expensive machines stand idle in the shed but during the harvest they're on the go almost all the time. trucks drive right onto the field to pick up the crop. that's efficient and saves time for the farmer. detail out for employees for people on his 900 hectare farm in eastern germany he may use high tech machinery but he does not accept the label industrial agriculture . or the reasons of i reject the idea of i'm the son of

a farmer and what we do nowadays is not industrial i don't think you can ever describe farming as an industrial industry i would call this modern agriculture a kind of solution but. once the crop is harvested fertilizer is spread on the field right away and another crop is planted. a regulation specifies how much fertilizer may be used so as to limit the amount of harmful nitrate in groundwater . in order to meet these requirements farmers have to use expensive measuring devices. the authorities check on compliance and penalties for violations can be severe. lover is angry about the fertilizer regulation he says it makes it harder for him to farm the way he thinks is right. and every year the amount he's allowed to use is

reduced. for dummett 3 lets it go and that means a lower yield. but then the following year the yield is even smaller. we do defend that yield is the basis for calculate. the amount of nitrogen fertilizer for the year after that. i gave it up at all minus 20 percent over and over again. it's like giving somebody 20 percent less food every year. people tend to go for to keep that's how it works our fields are slowly starving. at some point we'll have no yield at all. farmers in the european union receive subsidies from brussels deter love for this case that amounts to more than $200000.00 euros a year but it's a gift he says he'd rather not receive he says crops should command higher prices food is simply too cheap with the machinery equipment is getting more and more

expensive as his diesel labor costs are rising as well of course that's a major factor in farming and we don't want to be left behind. while the rest of society earns more and more we farmers are less and less we're always being accused of demanding subsidies but we don't want them we want fair prices and that means at least 30 percent more for grain milk and pork then we could do without subsidies. now since only if it's. teacher allow for his neighbor is also under pressure financially a new animal welfare law means he has to upgrade living conditions for his picks. just sundays case and his employee catarina who may keep the south who've given birth confined like this for 28 days so that they can't crush or otherwise injure their piglets. now each stall has to be enlarged that means there won't be

room for as many cells in total ditto it employs 2 people to look after the pigs now he'll probably have to let one of them go. i suppose it'll make it looks like we'll have to give up pig farming this shed was built for $185.00 cells we now have $120.00 and i think they each have a decent amount of space but you know if we have to rebuild and reduce the number even further it won't be economically viable for the following i can't do with just one employee what about weekends off and holidays i need at least 2 but i can't afford to pay too if we don't have enough sobs it just doesn't add up all together but if so catarina her in it is set to lose her jobs as situation dept says operation to the new regulations on animal welfare. there's been lots of rain lately and deter loafers combine harvesters have to stop

earlier in the day. that's an annoyance for the farmer but what really makes him mad are all the regulations but he says are forcing him to change the way he farms water were. given in the light of so far we've heard from the producers and sellers and on the other side of the equation there's us the consumers it's our business they want and supermarkets are willing to go to great lengths to get it undercutting each other in the process what we all have to ask ourselves is what are the consequences of these price wars. meat milk fruit and vege who has the lowest prices every cent counts competition is fierce someone a handful of retail chains that dominate the global markets. the world's biggest retailer is the american company wal-mart revenues this year are expected to amount

to around $470000000000.00 euros heavyweights among discount stores include germany's group which owns the legal and chains with estimated revenues this year of 120000000000 euros followed by algae with 100000000000. in order to sell their goods cheaply retailers often put producers under pressure if you don't give it to me for such and such a price you're out. it's not just discount stores that push down the prices they pay so do more upmarket chains like $80.00 and i think. if their suppliers won't sell to them for less they'll even kick out huge corporations such as nestle coca-cola and unilever. small farmers sometimes find their deliveries of fresh produce turned down agreed prices reduced retroactively or payments delayed by the retail chains tricks like these have brought farmers out onto the streets in protest. but the retailers hit back they say there's no escaping fears

international competition and in any case many shoppers can't afford to pay more for their purchases. if you ask consumers most say they would be willing to pay more for meat and milk but when it comes down to it the majority still choose the cheapest items. scandals over factory farming and exploitative working conditions on farms and in slaughterhouses have made cheap food a political issue. what's the answer break up the big retail chains have governments dictate prices. but that sounds like socialism. an act stricter laws to protect workers animals and the environment that could raise prices. and equitable system of production and distribution is impossible given the pricing power of major retailers it's a power struggle and the outcome is anybody's guess. if you are like

me use all of oil in basically everything it's affordable it's meant to be healthy plus it's a key staple in the so-called mediterranean diet which apparently helps you live longer consumers love it but many of those who make the oil can't seem to make a living from it the world's biggest all of oil producer is but the all of all farmers say being at the top doesn't mean much in the face of shrinking profits one farmer and the new c.e.o. whose family has made all of oil for a century took it upon himself to take his production into the future. khan is passionate about growing olives his trees grow on 100 hectares of land some of them are over 100 years old. they don't start in with this olive grove. these trees were planted by my grandfather in the 1920 s. . and i mean. since then he's restructured the olive groves so that he can live

from selling all of the oil he planted the trees closer together and started watering them which used to be unusual now me again harvests a 1000000 kilos of all of the year between october and february but their value is going down. the other but if you know the price of olive oil has fallen a lot that our profit margin is so small that many olive groves are no longer profitable. at today's market prices a kilo of the finest spanish olive oil only fetches 2 euros in the country 4 years ago it would sell for twice that like almost all the all of growers in the area began used to send all of his all of us to one of the many cooperatives in the town of plentiful but with so many other farmers doing the same his own oil was getting lost in the mix which he found disheartening. i decided to return to my roots

grandfather pressed the oil himself and sold it directly that's what my family and i wanted to. pass 2 years ago they decided to market the oil themselves in nearby. miguel's brother take care of the business side polio posts ads on facebook and google at 1st they were only for the spanish market. and i had no idea about e-commerce i had no idea how to sell a product online. it was an adventure and a challenge but as it. same we managed to put this beautiful project together we wanted the. business is getting better and better they've employed 2 people to stay in direct contact with the customers at the beginning of the year they started discussing which new avenues they could take and decided they would expand into all

of europe while spain was in coronavirus lock down the warehouse in plant to fania was receiving more and more orders it was funny we just wondered what would happen if we started taking orders from abroad. and it was an even better outcome than any of them had expected you don't get it but it was unbelievable i think i mean within 3 months 30 percent of our orders were coming from elsewhere in europe and in the book and have been especially from germany. money. the direct marketing worked out well but they're still not in control of all aspects miguel still stores his oil in the cooperatives tanks and he needs help extracting the oil from his all lives. more still not completely independent from the cooperative we need help from them to press the olives we can't do that without them and we need help filling the bottles.

but he hopes to soon be fully independent again is already making more money than before the customers can buy quality all of oil directly from farmers in under luciana at a price that can compete with supermarket brands the new business model has already begun to bear fruit. and before we let you go it's confession time for me i. am terrible with plants so i won't likely ever to own any kind of weekend garden house or allotment but for many people these gardens are a source of pure pride and joy this week we handed our olof krieger a pair of hedge trimmers and told him to go wild he may have taken it literally took one sec one sec just this all has to be trimmed the allotment long.

for him check check check check check. and. he threw up on my he gets away from my hike sharia. ok he's doing it all wrong i look. at this the order of honor what he thought but when you have you a much better ahead of them is on the back. just look carefully. you can find a lot man so all over the world and london paris moscow everywhere. these

if this one is 100 years code how is the $1000.00 and it's a pretty year so off them all. it's. really lovely red cherries. sour sherry's. just. did. some things off much shouldn't have. you know. this means trouble. it was yesterday and i have to talk to eric out because of well this should be there.

because most of the democrats and kill what will you do with so many cherries and gooseberry send all the rest it's a lot eat it all. you really want to know yes of course. i make jack i make reserves and i freeze stuff to eat in the winter this is do you know how good a store tastes in the winter. get i've got i can't imagine what i was over at that forest gatto with homegrown storm breeze and cherries of course. i would bet my huts the most important thing i couldn't live without was house by sickness conviction. we have always saw me cutting the hatch do you think i have talent. yes really thank god really and if you want to do it even better i can show you how. to.

be often been a transaction i often walk past gardens like the sand wondered what kind of people are they appeal to you over strange and. yet sparse now i know it's just wonderful to get away from it all from work in the office and it was de monsoreau on the system for it's so relaxing. soon there will be pouncing this growing over that. potatoes for the obvious stuff i platens. seems like olaf has a thing or 2 to learn about plant. just like me maybe erica can teach us both to grow our own food that's all from this edition of made i hope you enjoy the show by
