how does the virus spread? why the repairman and when will all this 3 of the topics that we've covered in a weekly radio. if you would like any more information on the corona virus or any other fine topics, you should really check out our podcast. you can get it wherever you get your podcast. you can also find those w dot com, forward slash science. oh, it's the biggest vaccination campaign in history. almost 2000000000 doses of code 900 vaccine have been administered worldwide to date. but is it enough to wipe out thought code to the virus keeps mutating. and each change makes it harder to control. 4 major new variance have already been

identified. alpha beta gamma delta. but there are more letters in the greek alphabet. researchers worry, they'll soon have to use them for new cobit very in many areas of the world are still waiting for their share of the vaccine supplies, giving the virus a fertile breeding ground for fresh mutations on you. outbreaks in the corona, virus pandemic. the welcome to occur with not in special, i'm wanting to jones. good to have you with us. now let's just he is that again, almost 2000000000 shots worldwide funds. quite an achievement. but of course, those shots are not even these spread across all continents. in terms of sheer numbers, north america and europe managed about 370000000 shots each south america

with koby district and countries like brazil, as a lot of catching up to do africa. and it's more than 1300000000 people only received 34000000 doses so far. while asia is storming ahead with more than 1000000000 shots. but that doesn't mean it's fully vaccinated far from it. there are huge gaps like in vietnam, a country that has long been praised for his response to the pandemic. now, it is faced with new outbreaks and a new variant. the discomforts of the pandemic known to many around the world. and now common in vietnam to ortiz, in hotel, in city of ramping up covey. 900 testing. first focusing on high risk groups, residents are on alert, made fast, rising case, number's calling me. i'm more worried about the new virus variance. i have to r a mosque more often than before, outside, and also limit meeting out this. po,

cima in city has been partially shuttered, with many businesses closed and public gatherings to restricted. some residents find themselves behind quarantine cordons amid local outbreaks, students vacating their dormitories to make way for a new hospital in preparation for the worst. the last flight into her noise, her atlantic, the busy international airport is closing for a week. the government to feed the countries outbreak was fueled by a new coven. nice hint. but w h o. research has have confirmed that most cases here were caused by the delta variance, a previously documented strain of the virus. vietnam is in a race to vaccinate. so far, only about one percent of its population has been and not lated. only weeks ago, vietnam had achieved a month of 0 community transmissions. it's strict arrival quarantine measures and

fast lockdown proved effective that covey 19 is finding cracks in even the most cautious countries. for more let's bring in professor shout and they have from the be able to send to the center for molecular life science of the university of basil in switzerland. let's clarify the situation in vietnam. first of all, is there a new variant? and if so, how worrying is it? yeah. so what we know from vietnam at the moment is that they, they are observing the very end of the areas that cause the big outbreak in india and some of the genome se they described over the last few days. they have an edition, a deletion that position $144.00, the spike protein. and that is, what is the case of mutation that seem previous the, for example, in the various alpha, the one that originated in the u. k. but that in itself is not really to worrying your concern. if you have denise in that position 144 before. all right. and

mutations per say, i'm the worrying either as far as i know they're normal because that is what viruses do in order to survive. so why all the fuss about new variance right now? yes, virus, this particular aren't a virus. if they, if you take all the time, they have a fairly, very sloppy replication machinery, that means that they don't change sort of step by step. but you know, some of these and actually a small fraction of these mutations, they allows of viruses to either evade existing unity or sort of become more transmissible, more adapted to the, to the human host. and they, by of cause new outbreaks. and in our secondary ways, 3rd way for waste and bases that have already seen such sort of larger ways of commitment t. and that's in what if occasions, adaptations of the virus to the new environment are concerned because it allows for

resurgence of the panoramic right. and that's why this is why it is so important for us to do sequencing sequence in order to, to keep track of what kind of very into a dealing with so that we can hopefully respond. do we actually have a chance to ever be ahead of the virus or we will always lock behind while sequencing, as you just said, allows us to spot new marian's early use of allows us to see how, how different areas that are circulating different from each other and the mutations that we observe in the genome with the virus and through sequencing, they give him very early on, on how these viruses might behave. so for example, if that how potations and specific spots lost the virus that the interest in the 2nd, i think that would be a cause for concern, because that might mean that the music is over list, you know, protecting less well from this particular parent visit. these very,

very sort of intense sequencing activated efforts that we have in place now we do have a chance to, to get on top of that early. and so at least see any changes in the bio population before they become common. and i think that is sort of a big, big badges that they have now what to do to be if you know, if you want to go ok. and of course, the other weapon that we have, if you like, is a vaccine this week, we're closing in on 2000000000 shots of code. 900 magazines will light, but will light years away from global herd immunity. with a huge discrepancy between industrial and developing nations, how big is the danger that this discrepancy will create a strain that could eventually escape and unity? whether the important part is that we have to bring case numbers down because you know, you can, you can emerge both by infecting the vaccinated people, all the people that have had a previous infection. and there are reasons to believe that a previous infection is not as protective as a theme that is, that of more conducive to generate,

generates new variance variance. so brain case number found is pretty to think that matters. and to do that, we need to bring an explanation to, to the entire globe. and of course, there are different vaccines and some vaccines. i said to work better against certain variance than others. but vaccination is still key because some people don't seem to trust vaccines anymore. what do you say? while it is sorry, can you next? do you have been, you know, our most most powerful tools against infectious disease and you know, i have every reason to expect that the same is going to be true here. and it is important to remember that, you know, like the nation enlisted. so the multiple layers of being in protection. and most of what you're talking about here with ms of areas of antibody is cake mutations, meaning a specific, specific aspect of the response might be less effective after that. but there's every reason to believe that particular protections again is disease remains robust

and is not so septal to change it by variance. i professor, they hadn't had there from the center for molecular life science at the university of buffalo in switzerland. thank you so much for your time. you're welcome. thank you. one year into the pandemic. there's already a variety of scenes on the market with more on the way the questions still remain about the safety of vaccines for young and old alike. science corresponding derek williams takes a look at the astrazeneca, jap. oh, nice the present. a convex seen apparently see from age are people. oh, 1st of all, i want to emphasize that the data shows that for the vast majority of people, the astrazeneca coven vaccine is both safe and reliable. but in extremely rare cases, it has also been linked to the development of potentially dangerous blood clots.

there's going to scientific scramble to, to try to figure out exactly what's going on. and experts now thing that in those rare individuals substances produced by the immune system in response to the vaccine can also activate platelets in the blood which, which leads to the clotting. because it happens so rarely the statistics aren't conclusive, but women under the age of 50 seem to be affected. most often. that's led national health authorities in some countries with arrange of vaccine options to begin recommending the astrazeneca vaccine primarily to those over the age of 60, where we're links to clotting. we're not completely absent but. busy much, much more tenuous. it's pretty amazing actually that we discovered these needles in a haystack so quickly and also that we already have a pretty good explanation for,

for what might be causing that. i couldn't find any study explaining in, in metabolic terms exactly why this particular side effect seems to impact older people less often than it does younger ones. but, but many experts think that the idea that the clotting is basically caused by an immune response that that could explain it. we know that as people age, their immune responses tend to damp and down. and, and in this particular case, back could be a good thing. and with all the other data we have about the asked presented vaccine showing it to be safe and effective. it remains a very powerful tool in our arsenal for protecting the elderly in particular, who are most at risk if they catch cobra 19. hence the recommendation that

they continue to receive it, me well, vaccination in some regions as advanced enough for them to open up again in riyadh hundreds gathered last night for the 1st concert in the saudi capital. since the start to look over 900 con damage, ah, my performance isn't a live audience. some things to look forward to that's all for today. thanks for watching. ah. the willing to get to go beyond deals? yes. as we take on the world, we're all about a story that matter to you the

find police and then we are here is actually on fire for mines me. oh, can you hear me? no. yes. yes we are you and how is germans house we bring you back or never? right. just so with what is what it was to is medical really what time and walk we talk to people who follow along the way, admirers and critics alike. and how is the world's most powerful woman shaking her leg is paid? join us for macros last we don't want to see them. what they are, their street, our water, our air,

your eyes to be on. our new global 3000 series. threats from your facing. the heroes taking a stands. it's not that i have to make up the global 3000 theories starts june 21st on d. w. in the germany's greatest poets, your hand was gone on. good to one said that he liked to call architecture frozen music, which invites us to consider the effect that architecture can have on the senses. well, that is the gist of today's edition of arts and culture. so welcome. and we've got these stories coming up. architecture that he'll the maggie center network of

cancer support centers in the u. k. strive for spaces that envelop us like an embrace. architecture. the cheers, berlin based artist, tina. you could, she creates colorful, expansive neural to transform public spaces and buildings. but we are starting off with architecture to change the world because nothing less than that is and i hearing her vision, she believes that can transform and improve lives on multiple levels, be a cultural, social, economic, environmental, or psychological. and she also sees sustainability as a synonym for beauty, which is why her material of choice is clay. something that comes straight from nature and endorse this. your video center in rosenheim, a city in the southern german state of the area looks like a huge bird. it's made of curable,

large seated willow is designed by a hanging a pioneer of sustainable construction. oh, li creates a pleasant indoor climate in germany. it's more expensive than conventional building materials, and it still doesn't have a great reputation. in fact, clean, has many advantages with stores, heat absorbs, harmful substances and it's environmental friendly. was telling i is also water soluble, and that's a very important and wonderful quality because it can easily be recycled. clay can also be repaired very easily. if an edge breaks off, you just do the same material to fix it by pressing it on top of the crack. so that was me. the end, it's available everywhere. it's literally beneath our feet. change as another can be worked with manually without the use of expensive machinery and hearing

a discovery or passion for the use of local resources at the age of 19 year abroad . and back with a few years later she carried her 1st construction project there. 0241. her 1st award for school in woodruff for india. so she designed for her thesis. ah, ever since everything has been building with clea, i'm with a clear conscience. initially in asia and africa. ah, in 2013 instruction began on these hostels. me to frankly, students and bamboo in china. this was out of hearing a contribution to a long chat international b and the design is reminiscent of chinese lanterns. she completed the daycare center in san parkway in 2014. 0, your sustainable building, cause that is in demand worldwide. she teaches harvard immune answering and is one

of the few women to run her own architectural firm. again and again, she feels drawn back to back with me. participation at equal rights to the bowl village. both men and women joined in to build this award winning to story therapy center for people with disabilities. the 1st building, medically in europe, went up in 2016, a birthing room for upper austria. ah. once the project includes in the video, is completed to move on to the next construction site. this time and in the last needing how many color nuances play has from reddish yellow issue to dark brown. you don't need any chemicals. for instance, this will be,

our problem is that the cannibal alternative is always cheaper and that definitely has to change this pioneer of sustainable building knows there's still a long way to go later. hope you might hope that architecture can really be a tool for improving living conditioning and bolstering social justice and cultural diversity. quickly. diversity and can help preserve this planet for generations to call fiona and with every new design and a hanger comes a little closer to achieving that goal. she may not change the world from one day to the next, but every step can me. looking back to history, it's quite obvious that the best architect, so those have understood that architecture and the human condition are tightly intertwined. and that the shape and form of spaces, both interior and exterior, can dramatically impact our mental and physical well being. well,

that was the thinking behind maggie's centers, and they enlisted the professions heavy weights to create places of refuge and healing. oh, this is maggie center in leads, england. it's a place where cancer patients or their relatives can receive practical or emotional support during treatment. it was built on a hospital campus but stands out in stark contrast to the other buildings around the architecture and interior design with it. soft curves are meant to be inviting to both patients and other visitors. ah, when people come here to this big, beautiful space, i feel really safe and calm away from the clinical area over the hospital. in fact, one less a thought was how it feels like a warm fluffy pancake keeping. the interior of the center contains natural material. sauce lighting and numerous spaces designed to encourage social

interaction. the would use is sustainably forested bruise. the walls are made out of porous materials, such as limestone, which help ventilating the building naturally. as you come into the sense, obviously, the big stair and we know that comes through as been shrouded in fi, christie. but this gives the impression that we can be open about that now. and we can talk about cancer and we can talk about that as a thing that's happening to people as they come into the center. but then we have much smaller spaces that have no corners. so they envelop you as you go into the celia nice husband was recently diagnosed with leukemia. maggie centers helped her cope during his treatment. i have to bring my husband off so he doesn't drive. so the center has been incredibly helpful to me as

a comfortable place to wait. while his having his treatment maggie center and leads was completed in 2020 by british architect thomas herwick. she base the design on oversized garden, planters with the goal of enhancing the greenery around the building. he says, architecture plays an important role in our well being. ah, this was really interesting for us because i think an issue of our time is how buildings affect us emotionally. and many buildings have failed us in the last century or so. emotionally, they've made bad places and you couldn't get a more extreme need for something that connects with people's emotions and feelings than a cancer care center. famous architects have taken part in designing the center centers that hi div. frank geary with this center and done the scotland. norman foster and

rim cool has with this center in glasgow, scotland, american architect, daniel leaders can't, is working on the next maggie center in london, making it the 25th in the u. k. executive director dame. laura lee has been a part of the center since the very beginning 25 years ago. so the 1st market center came about 3 women called maggie catholic gangs. maggie herself had a diagnosis of breast cancer and she did to fight aspects of care that weren't being provided within our system. here in the u. k, the 1st center opened after maggie had died. when we were asked to work on other centers, the other hosp to grains her friends who happened to be frank gary to draw chairs norman foster. then offered to to help and who wanted to take part in providing a maggie center and different hostile grains. maggie center in lead just one

example of how architecture can help in the healing process. the speaking of healing a smile can also have a therapeutic effect, which is my soothing colors are cheery images can transform a dr. cityscape. i could, you know, you could, te, enhances buildings all over the glow with his monumental wall paintings. invite you not only to smile, but to linger in the italian city of south of rome. a giant meal is being painted. the city has commissioned agostino corte to redesign the library so solid. this is my biggest mural so far. and so it was already a big challenge and those, so he's the 1st time i'm painting a full architecture on each side. so it's a kind of a dialogue between my paintings and the existing space senior you could,

she has been working on the 700 square meter bureau for 12 days. using about $300.00 leaders of his idea is to reinterpret permit his cultural heritage. drawing inspiration from the fall of g traditional stories august your course, she's liking style is composed of geometric shapes and vibrant colors. and his neuro can be viewed the world over. for instance, in tai pay and taiwan. in the mexican city of monterey, or his craziest job so far on the metro station in the indian city of new delhi. since 2017, the italian have been living in berlin, where he not only focuses on paintings,

but also works on sculptures and installations in his studio. he experiments with a variety of materials such as crafter was my work is very like kind of architecture, very simple. it's closer to drawing them to painting somehow. and so the same i tried to play around with bought them. so i like this mix of nature and the key texture somehow. in from next year. how could she was mural to build a bridge between the cities architecture and the modern world? the artists approach has one over artistic director, my channels, my early work up a she's the, the go to the guy. he has the great ability to take traditions of ancient rome and painting most of you to understand calling for the in particular out of the painting of roman policy that we still owe 580 it sort of, overarching. as

a result, he appeals to a broad audience to makes art adjustable to go to expense on a people are a little bit even if augustine coaches art is not destined for the ages, the mural at the library and palm, etc. i will certainly be seen for some years to come a breath of fresh air through arts and architecture. that's all for this time. so thanks for watching and all the best from us in berlin. ah, this is shaping the continental views, africa, the were gone, men. what's making headlines them? what's behind the industry to give you enough reports and all the trends that my time to
