it's a strong mandate to govern at a crucial time. and as your news update at this hour don't forget you can always get the latest around the clock on our website at www dot com or you can follow us on social media that's twitter and instagram absentees opinions of richardson in berlin for me the entire news team at such watching. the fight against the corona virus pandemic. has the rate of infection been developing what does the latest research say. information and context around a virus update 19 specials. on t w. children to come to. one giant to problem and. in no mood to seem to be cheery and.

mean by it it may be changing late if you can't get it. how will climate change affect us and our children. learn more e.w. dot com slash water. the world spent 2020 on defense. trying to play catch up against a fast moving pathogen with simple tactics like mosques or social distancing. but in the medical field innovation became the name of the game scientists develop vaccines at breakneck speed putting governments on offense there are no killing whole populations 2 outs. facing prickly little competitor and looking at other

ways to innovate our way out of the crisis. a survey by the consultancy mckinsey shows 90 percent of executives from all fields expect covert to change the way they do business but it's an opportunity few feel equipped to pursue the study also shows commitment to innovate fell last year except in the pharma and medical sector. is this simple lightbulb a weapon against the coronavirus. rosario violence think so together with other researchers the doctor invented this l.e.d. lamp its light has certain frequency characteristics which could destroy the coronavirus. this light bulb is similar to an ordinary one you screw it in switch it on and it works. in the light and then destroys all microorganisms by destroying their structure that is the outer membrane and in the

case of the corona virus probably also the protein spike the sting. used by. this is already worked with bacteria and a series of experiments carried out by the researchers together with the italian military have now also shown that the special l.e.d. light destroys the corona virus and it's not harmful to humans either. now we have to fine tune the whole experiment in some way because we must not forget that up to now we have done the whole thing and laboratory conditions which are different from the normal environment. the coronavirus pandemic in italy has also inspired other inventions for instance when ventilators became scarce and hospitals and doctors sounded the alarm these young researchers quickly developed a valve model and their start up company the valve can be produced with a 3 d. printer and attached to a standard commercial sports snorkeling mask. the next day we took this to the

hospital they tested the ventilator for half an hour then a doctor came and said they work we need $100.00 of them within the next 24 hours. another new invention is this anti covert carpet it reduces the amount of bacteria and viruses carried into rooms from outside step on at once and your shoes are disinfected the carpet automatically releases disinfectant when it senses when. the inventors of the anti coronavirus lamp hope they to consume implement their disinfectant and hospitals and schools. and let's talk to a columnist get a hostile force from the swiss science and technology institute. a lot of the know how behind these sorts of inventions was around before the pandemic why weren't they already in existence i mean they would have made our lives so much better and could have stopped more than just the corona virus also the common flu and many

other things. that is true and that's a very good point you say that necessity is the model or if inventions are now reaction see the needs for these new technologies. and decide there is no. barriers we need to guide these credits which did not exist before and certainly not to the same extent so we actually do as young person you know vision because of the needs and markets. and then we seem to be outdoing ourselves on other levels when it comes to vaccines say developed a record not only just one we've got more than one. it's and we might be worried that we are wasting money on the $1.00 hand we are putting a lot of resources on developing facts and research there has been more than $200.00 . minutes but. and so as much as you know we praise the winners and we might even complain that they need to make money we should not

forget that a lot of actually losers and very long. and just. using a lot of ways to competition in other words we could be working on other fronts not just vaccines but also treatments and. yet more than that so of course we're putting a lot of money and brains into comics ready to eat but we should not forget that the earth is other problems that we need to tackle and so we've heard a lot of research hour with from from all of these other questions so as much as research is accelerating we might be worried that there is a slowing of research in these other. she's a science back to innovation what about the sharing of the knowledge of something like a vaccine as some of these companies are holding on tight to their pay and sunday. true lots of knowledge has been shirts science has do talk to each other and we

know a lot and you know we collect information from from various from countries and institutions never the less the fact that firms wants to keep their ip rights for a lead it's just business as usual and i know that some some some some people in some countries complain about you know that it's strong and important to fight for a vaccine research to be good but we should not forget that firms private firms emergency to card use those as boston on the. government can actually save the patents parties ask for compulsory licensing and start producing the facts and themselves so based on that what would you say the role is that money does play in innovation in this case is that profits that's driving innovation these big divisional profi is simply driving. innovation. but nevertheless many many many people in the pharmacy to get it is 3 are not just

much of it that might go in you know these are people working on you know. people to really care about getting out of the crisis and out back who are mississippi is the mother of invention that is you know very broad as well of course isn't it also in times of crisis and when there's a lack of funds that we become more innovative that is very much true and we have seen so pricing we lower costs you know they should say i do the early days of the underneath respiratory device and we're seeing very very creative solutions and it's also history suggests companies that invest in innovation through a crisis outperform is in the recovery. is that what we're going to see in this case do you think. most likely. a crisis is the group that is a good soundtrack to invest in innovation but it's very short forms and felching and he can afford to do so and we should not forget that research has been i mean

you know issues research and innovation not an incoming book in general has been slowed down people have to stay at home that might not have easy access with a laugh so it's extremely challenging to make there not hide it if you ration very despondent in particular and the big question will we innovate enough to prevent the next pandemic we don't be able to prevent the next and then but we can certainly mitigates effects and the only way we can do so is by keeping investing in a strong science society we need a strong science because then we need to fund universities but not on the rest and need to have. an appropriate me gratian so think of that of the developers that pfizer by you in. one of of the guests is actually a turkish migrant right and so we need to work on a strong science system and that goes as far as you need ration policies an indication ponces and it's on me with you know high performing knowledge states

that will be able to meet to get us out of the mexican didn't get us from the p f l thank you very much for being on the show today. thank you and he's our science correspondent derrick williams with your questions on the coronavirus. what lessons are we learning from coverage 19 that might help us deal with the next pandemic this excellent question has way more answers than i can go into here but some lessons are obviously more important than others at the top of the list i'd say is what we've learned about rapid response a sars khufu to completely outran our ability to get on top of it early because it could spread faster than we could react i don't want to go into why or who supposedly did what wrong early on because because i think it makes no sense to

play the blame game but it does make sense to look at how we can speed up international response to spillover events like the one that started this pandemic because if you can be certain of one thing is that they're going to happen again in the future and that means in my opinion giving the w.h.o. or a successor organization the money and real backing it will need to recognize threats declare emergencies and react faster and more independently of the nations that make it up a 2nd important lesson that people have learned from this pandemic i hope is that human health doesn't exist in a vacuum that it's closely tied to the health of the environment we actually all know that already things like air or and water pollution kill millions of us every

year and and the repeated emergence of new diseases is directly tied to the fact that we know really can and do go to pretty much. every corner of the planet while destroying the habitats that act as buffer zones between us and pathogens that can jump the species barrier when that happens that science can help but it can't provide instant fixes and where science can really help most i think is not in the accelerated development of vaccines although believe me that's been really amazing to follow but instead now through its potential to help us reach the longer term goals a greener more sustainable society it's ones that recognize how dependent our own health is on the environment around us. on they forget fine dining in the pandemic but that's not stopping stock shifts from opera falling

improving the was we on leave it as well as drawing attention to the problems that i gently need solving well here are some of the topics coming up on the program. because. transportation diplomacy made in africa and example from kenya. popcorn and why it's not just for eating as scientists in germany will demonstrate . on tonight a course of a shift in south africa sparing young people to protect wildlife. but 1st a week heads to namibia more than 20 percent of the country is on the course of asian one isn't it is home to incredible variety over a rare and in danger of species of animals including the cheetahs the so-called cots in need of very specific kind of environment to breed can't unmaintained the aborted temperature when it gets very caught the trouble is that they often leave

india rural communities and cause problems for people and their livestock now researchers hope for a way for farmers to drastically of course reduce their livestock losses without killing the beautiful big cards. a rare sighting of the chicest in the media. the country has the largest free range in population of cheetahs in the world but according to recent research still numbers. here the population is threatens because it doesn't look inside of national parks but on commercially used farm that there's obviously needs to conflict as the. livestock of the farms. teeters population numbers across africa have dropped to less than $7000.00 worldwide as the a habitat that's lost to farm land and house and cost russian portion and illegal

trading cops pause a federal challenge and because the test attack life talk they also get killed by farmers. scientists from germany is like nets institute have found a way to reduce that conflict dispensed more than a decade study to test in namibia part of their study involves putting video collis on the animals and monitor indian movements the team not to study the cheetahs always return to 7 areas of practice passed on from one generation to the next they visit these territories and mark read in the territory so we call this centers of the territories not a marquee trees are we call the communication hops because territorial males they used these trees and also the olders into region around so these territories are very stable they're always there and even if the territory hold us

does appear die then the new will territory and hold us up all day exactly the same place this allows the scientists to identify areas where cheetahs congregate the den and vice the farmers not to put a livestock in those places it's about 10 percent of the area that is highly dangerous because the concentrations of the cheaters is very high and about 90 per cent that is much less risky for the harmers and their cattle. the farm is that i've moved cattle out of harms way now there was far fewer animals to the big cats. and this simple adjustment region. the livestock losses by more than 80 percent and that solve the conflict for the farmers and for the truth is in many cases. reducing the conflict between humans

and money mouse means more teachers survive and other benefits to these powerful pre-dates has helped keep the populations of the most under control thus preserving i'm maintaining vehicle logical balance off. what incredible creatures and what a great idea to promote a peaceful coexistence between the wild animals and the humans on this report is about a really interesting in south africa it aims to help communities live alongside animals in the wild as well as offer professional opportunities it is called the truck a company and as the name suggests it trains disadvantaged rural people in the traditional skills of wildlife trucking. the city sunny and. looking for this special friends in the dense bushland of the level of north of

johannesburg. a group of rhinos is hidden somewhere here. this is their front 2 pens. and. spurs on the ground twisted twigs and droppings lead them to the animals. their professional track his. ancestors they were doing with reckon you can. eat for meat for hunting they do eat they did they through they studied and we are just getting on when they offered back in a different way because then they would do we need for food we we have do we need for the for the well not to. kill but to protect. track his play a critical role in keeping the animals in the reserves safe. south africa has

nearly 80 percent of the world's rhino population and has been hardest hit by poaching but says 2014 thanks to strict security measures reserves have half dry no killings from 1200 animals to about 600 in 29000. to keep his animals safe conservation manager had money does not only rely on devices. but they really do a lot of monitoring work especially. on conservation important species like. some of the big cats and so on we were various forms of technology to try and track these animals and keep tabs on these animals but technology fell on you from time to time. and then we have to revert back to the basic. tracking skills. this m r a reserve is part of the great career a semi desert region with characteristic wildlife vegetation soil and climate

conditions the reserve is also one of 3 training grounds for a very unusual tracker cademy today is examination day. has to show his instructors he can track an antelope in the semi arid karoubi. it's a different one because even when richard. in front. i did track reads the environment and develops an intuitive feeling for the ways and habits of animals droppings are just one of many signs they read. just finally label hung metal finds his target hidden in the bushes. grew up in the area at night and $100.00. hours. in the most annoyed this more list ones who and then you know what are the biggest in the money going right. everything the inside. was getting that motivation therefore i want to go to to

learn about guns in the mine and everything the academy is an ngo that offers free training to $24.00 young rural people from various african countries each year realizing that only a few traditional track has remained in southern africa onyx when he 1st started this school 10 years ago with the help of a private sponsor meanwhile the academy gets thousands of applications pay here. we are training trackers to do for the benefit of conservation and for the benefit of an ancient culture and to improve the lives of the students that come through our program thickets and yet and it is proving successful 94 percent of all graduates are employed and the trackers are needed many iconic animals like crocodiles leopards and cheetahs remain critically endangered. after a long day of working and learning in the felt the pupils returned to the boarding house was after many of them heard of the tracker academy through people from their

villages who went through the program and subsequently found work in the reserves they hope that they too will one day be a role model for their peers back home. well the one who'll be on the vonage overboard in solar energy in 2018 accounted for 2 percent of wild white in the christie use it and its share is growing fast experts say solar and wind to us it to be the most sustainable sources of renewable energy in the solvent hemisphere the international renewable energy agency says that over the past because it costs all solar dropped by 80 percent let us now go visit an energy provider that is building the biggest solar power in germany. these panels are pretty easy to install but there are thousands of them still to go

. in the countryside near berlin germany's biggest solar park is taking shape. half a 1000000 modules built on metal frames. 100000 posts . 250 kilometers of cable. 150 fishers working on behalf of one of germany's biggest energy companies. we definitely have the potential to complete projects of this scale but rather than size it's the viability of the project that counts for you. this solar park is the size of 225 soccer pitches facilities in europe tend to be smaller because they compete with agriculture. but solar parks alone aren't enough here in germany there are 19000000 apartment buildings and houses

a lot of roof space. is an ideal place for solar panels. an entire industry has been built around installing. now adays the systems are very affordable and economical to run since you basically don't have any maintenance costs. have become so affordable to install that they quickly pay for themselves. out. mugshots owns a house with every top solar system in many cases the system actually produces more energy than a household needs. as one of the things that makes it financially worthwhile is that the costs of heating your house or heating your water are pretty low.

the equipment paid for itself in just a few years. after that the electricity produced is essentially free. max baucus energy needs do exceed what he produces though that is because his family have 2 electric cars that need to be recharged. off. solar energy is expected to see significant growth interim money. by the time the last coal fired power station is switched off and 2038 there would have to be 5 times as many rooftop solar systems and parks us there are now to cover energy needs. solar energy would then account for a quarter of the country's power i would push. south to germany's biggest solar

park project 10 years ago the operating company was one of the biggest nuclear power producers in the country. they still run several coal fired plants but that will soon be a thing of the past. these new energy sources will have to fill the gap they've become a central pillar in our portfolio. 2012 we've seen growth. all new and renewable segments including wind both offshore and onshore as well as solar. you know these technologies will account for about half of our output by 2025 i mean. the solar panels just keep on coming day even on day as. talk so sustainable mobility tend to focus on the big cities in ways to reduce

traffic congestion and pollution and of course make life better on you give me basis on protecting you and what if you get off because well it's not taken this off the optical innovation that was developed in take. place handcuffs off and why several 100 kilos and here in kenya's capital nairobi exhausted noise are not a problem for day laborers. kenneth quantize invention could make life easier it's an electric car cost that goes faster and can carry more you build in a system that. is the.
