the headlines: donald trump has halted us funding to the world health organisation, over its handling of the coronavirus pandemic. the president said the who had "failed in its basic duty and must be held accountable. " he also accused the group of promoting china's "disinformation" about the virus. more than one in five deaths in england and wales are linked to coronavirus. new figures show 6000 more people died than expected at the beginning of april — a record high. but there was also an increase in deaths from causes other than the virus. polling is under way in south korea's parliamentary election. the vote, using paper ballots, is taking place despite concerns that coronavirus will affect the turnout. voters must wear masks and plastic gloves and maintain social distancing. the result is expected to be influenced by the government's handling of the pandemic.

you are you a re pretty you are pretty much up—to—date on the headlines. it is about 2:30am. now it's time for click. this week: following phones to track the coronavirus. how to come together whilst staying apart. and now that's what ai calls music. hello. we are still here. and so are you — so welcome. i hope you are well. we are, and we have been working hard on a new—look click that will work when we can't get out and about as much. so my living room is now also my studio,

and welcome to my sofa. the good news is, though, you don'tjust get to look inside my house. we get to look inside lara's as well, so let's go to chez lara now. hello, mate, how have you been? i'm 0k. i've actually been pretty busy, albeit virtually, and luckily like you, i have one of these in my house. it is funny that, isn't it, yeah. how are you? alright, thanks. yeah, i think we both appreciate that we are lucky to still be working, which keeps us busy and keeps us in a good frame of mind, but i am missing the people that i can't be with, and we are all adjusting here as well. these are strange times. what we plan to do in the next few weeks is look at some technologies and gadgets that will help you during lockdown, whether that is to help you work or communicate or play or to help with the kids or to relieve stress, which is what we are going to do first, because this is an anxious situation. you have something that might help, right? i have. this is the somnox sleep robot.

now, the idea is that it sort of breathes next to you as you cuddle it. it is designed for insomniacs and it has sensors on it. it has got an accelerometer and a c02 sensor, and it will track the breathing rate of its user, and it will breathe a fair bit slower than than the person using it. the idea being if your breathing rate drops, you are more likely to get off to sleep easily, but i didn't have the greatest time with it. i have to say, it felt quite odd holding onto it. i can imagine, yeah. so i took it out of bed. yeah, it really did. i put it on the floor and what was even stranger was it was breathing down on the floor. but the thing i do have to say is when i tested it in the daytime on its relaxation mode, it did feel a little bit more like going to a yoga class and just getting your breathing right for that, so i can certainly see the relaxation purpose and maybe if i was a real insomniacs, it could help. and there are so many ways that we are seeing technology being used at the time of this pandemic.

as the virus continues to spread, some governments around the world have launched contact tracing apps which they hope may help control it. in israel, the shield app records gps location, storing that data locally on a user's device. so if someone gets the virus, they are asked if they are happy to share their data with the platform. so anyone they may have been in contact with can be notified. in singapore, the trace together app is hoping to do the same, but using bluetooth signals to monitor users‘ phones that have been nearby. this method, some argue, is more privacy conscious. i downloaded the app because it isjust easier for the contract tracers to contact me, or i could help them to contact other people if i was actually affected. until these apps, contact tracing had been a very manual process. the person must be well enough to answer your questions. he must be able to list down the details where he went and what are things he did.

and often we cannot remember what happened. the more we lose details, the more likely we can't control the epidemic effectively. many more countries are looking to launch contact tracing apps. whilst the uk is considering a similar one to singapore, the eu is advocating a single app with data protection at its heart. so contact tracing is really vital, and here is why. people move. they move quickly and they move a long way. now, these visualisations are from a company called tectonics. what they did was they isolated 700,000 mobile devices in new york and they followed them over just two days. look how far they go in two days. right, all the way across to the west coast. here is italy in early march, and look how many people travelled

to the uk by the end of march. so contact tracing looks at the spread of covid—i9 by following particular people as they move around, but what these visualisations actually show is how people move about more generally, and some governments are trying to use this information to look at how people are moving around, even under lockdown conditions. and they're not trying to get the data from individual mobile devices. they are going straight to big mobile operators. one of those countries is norway. 0slo is usually a bustling city of almost 700,000 people, but like other places around the world, lockdown is now in force to slow infection rates. however, outside the capital, it is vital to understand how the epidemic is spreading throughout the rest of the country. telenor is norway's largest mobile operator, with 80% of all data traffic passing through its infrastructure. so it knows roughly where

each phone is throughout the day as that phone hops between different base stations. telenor then provide the user location data to the norway institute of public health to try and track the spread of covid—i9. in our systems, there is knowledge about where people are at basically any time. so the trick here is to understand how the population is moving on an aggregated level. so if you understand how people are moving around, then you are also able to understand how disease is potentially spreading across a country or across continents. the niph takes this data, combines it with other information relating to covid—i9 infections

and then uses a mathematical model that simulates the spread of the virus to try and predict how many cases are expected in each region and when. we have data on hospitalisations in norway since the start of the epidemic. and we have data on the cases of imported registered cases to norway since the start of the epidemic. we can lift, for instance, restrictions, we can open the schools and close schools and things like this, and we can use a model to inform us about what is the effect of doing that. we are primarily forecasting for the next three weeks so that we can look at what need will there be for hospital beds and for intensive care, and that is very important for planning in the health services. the effect is not only on the epidemic itself, but on public health overall, and on the economy and society overall, that we will be able through modelling to tackle, manage this epidemic in a much better way than the world

has been able to during prior epidemics or pandemics. however, as always, anonymity is one of the major worries, even in times of international emergency. we are extremely cautious when it comes to privacy and what we are very afraid of is that individuals can be re—identified from the data. we count only groups of people larger than 20, because we believe it is very, very hard to re—identify all individuals in groups larger than 20. this isn't the first time that telenor has used mobile phone data to track the spread of diseases. previously, it has worked in bangladesh to track malaria and pakistan for dengue fever.

the models have helped the governments there design more effective national response preparedness. around the world, countries including the uk, austria, israel and the us are all seeking to work with mobile operators to adopt similar models to norway to try and prepare and possibly even contain the virus. hello and welcome to the week in tech. it was the week that tesla showed a prototype of its newly designed ventilators to help address the shortage in hospitals. amazon reserved space on its site for healthcare workers to buy covid—i9 supplies, including n95 face masks and hand sanitiser, and uber built a tool to help its drivers and other gig economy workers in the us to find temporary roles at other companies during the pandemic. conspiracy theories spreading online linking 56 technology to the coronavirus has led to at least 20 mobile phone masts being attacked in the uk according to mobile phone operators. vodafone and ee said their masts had been set on fire, and key worker engineers harassed.

meanwhile injapan, graduates have been able to celebrate their hard—earned work and maintain social distancing with the help of robots. students at tokyo business breakthrough university were awarded their diplomas while operating telepresence robots via video conferencing app zoom. self—isolating classmates were also present at the ceremony and also watching through zoom. quibi launched its mobile—based streaming service in north america and the uk. content on the app is limited to ten minutes or less, and viewers can flip between landscape and portrait modes. and finally, if you have been missing the orchestra while stuck at home, now is your chance to visit online. 215 musicians from the stay at home choir got together and gave their debut performance of vivaldi's gloria. singing the choir is open for submissions for their next rendition. for many, religion offers some spiritual calm,

but of course at the moment, communities can't get together in the way that they normally would. yes, so religious leaders are doing what they can to work around this. this muslim call to prayer in egypt has been replaced by a message urging people to stay home to pray. and the jewish festival of passover started this week, and that has been looking a little different too. we wash our hands. rabbi mendel cohen here has been doing his best to connect with his community online. as well as videos of what would be happening in synagogue, here, he is demonstrating how the seder, the first dinner of passover, is set up. and this easter‘s sunday service will also be different. sophia smith gaylor has been finding out how religions are adapting. with mass gatherings being banned, many religions have had to stop public worship. and with churches closing, many have had to be particularly innovative,

with some turning to live streaming. good morning, everyone. this is terribly exciting. st james‘ in sussex gardens in london is one of the churches that's been experimenting online. we were determined that the worshipping life of the church should continue, but it would have to continue in new and unexpected ways. when the coronavirus crisis started, they began live streaming their services on facebook. but they haven't stopped at that. we have a large group of families, large number of children, so we wanted really to provide something that would speak to them, comfort them, encourage them and build them up in the faith, so, yes, we threw our all into a rather madcap virtual sunday school. it's palm sunday!

every week we send out a e—sunday, which contains within it the readings for the day and other notices and other devotional materials, and also an activity, so families download the activity. we are going to make our very own. this week, we made crafts for easter. for palm sunday. yeah, for palm sunday. and then about two weeks ago, we made this virgin mary. yeah, it's been a lovely way to maintain continuity now that normal life has been... there's a bit of a hiatus in normal life and it has been a lovely way to sort of maintain a sense of normality. there has been a big focus on web resources, like achurchnearyou.com, that is our church finder. it has been a really, really key resource for us in recent weeks. we have now got more than 3,000 lifestream services listed on that site. as someone who is

a regular churchgoer myself, i can't wait for that day when, on that sunday, i can walk back into my church and see family, loved ones and friends for the first time... i'm feel slightly emotional about that. all of these digital responses to this crisis have undoubtedly changed how people interact with faith online. but what will be interesting to see is how much of it will remain after the coronavirus crisis is over. that was sophia smith gaylor, and i am joined online now by the archbishop of canterbury justin welby. archbishop justin, thanks for taking the time to talk to us. spencer, it is a great privilege to be with you. i am very happy to be here. we have just talked about some of the new online tools and services that the church is providing. how do you think they will benefit people? you will have seen, and i know you have seen, churches using live streaming, which is having a huge impact.

there is a service a couple of weeks ago which reached 12 million people, ten times our normal total church attendance. that is remarkable. you couldn't begin to do that in the past. the best you could have had was a nationally televised service. here you can have everything from a nationally televised service to something that is just relevant to your village, your town, your part of a city, your part of the world. or you canjoin in something from anywhere in the world. we had comments from something i did online — i won't to say from where, but a country where it is very difficult to be a christian in public, you are not allowed to worship or own your faith in public — and they had a message saying, i haven't been able to go to church, but i have justjoined in a service with the archbishop of canterbury. there is a cloud to every silver lining, but i think the service

was what mattered. and technology is transforming the reach, the ability to comfort, console and encourage. it is a time of several religious festivals at the moment, it is easter, it is passover, ramadan is coming up too, and this is traditionally a time where families and friends would come together. there will be people who want to come to a church. what would you say to them? well, what i would say to them is, you know, that is me as well. the idea of not being at an easter service, i can't remember any time i have not been at an easter service in the last more than a0 years. and so it is going to be very strange but in the earliest centuries of christian history, church was in the home. and these wonderful buildings we have in the uk, these amazing

historical buildings, are treasures, but they are not essentials. we can worship, and christians all over the world do, without buildings. the technology side is giving us a sense of a resurrection of generosity, of kindness, of contact, of care for one another, and i suppose both the challenge and the hope is what we are doing with each other and for each other now, and that sense of mutual compassion and support that technology is enabling, will be carried on in the new world, after this pandemic has died down. justin welby, archbishop of canterbury, thanks so much for your time. thank you, spencer, very much indeed. music is a lot more than just a collection of notes.

packed with creativity and emotion, it seems like something only humans could make. but that could be about to change. i have been meeting musicians around the world who are embracing the machine, and i started at imogen heap‘s house. so we have been lucky enough to be invited to imogen‘s studio, just outside of london. this is a place where what many of her hits you might recognise, and also the music for the harry potter stage show, were created or worked on. and now it is being used to create something a little bit different. imogen sings. imogen has been working with artificial intelligence researcher tom collins. many of the underlying parts of this experimental, unreleased track were generated automatically by his ai algorithm. we are the shadows behind the shadows. i thought that was

the ai in everything. no, i love it. i love the challenge of this is going to be different. it has generated a song i would never have written, because it is taking me into patterns i would normally have not done, so i have had to go, how would i do that? and how would i transition from this to this? it is doing what i hoped it would do, which is what i believe ai will do for music and musicians, which is to push us to the next level of our own creativity. this song is still a work in progress. imogen isn't the only major performer that tom has been working with. # fade out...#. performed by tom and his family but composed in large part by the ai, tom is hoping this track could be the winner of the first ever artificial intelligence eurovision song contest. did someone say eurovision? yes, well, coronavirus may have forced off the human competition this year — the ai

competition is still on. what a relief. the ai song contest is a contest for computers actually, in short. different teams from all over europe and australia are given the job to create a new eurovision song with the help of ai. the german team databots have previously made a name for themselves with their 24/7 live streams of ai generated death metal. here is a taste. death metal plays. well, if infinite death metal is not your thing, maybe their ai eurovision entry that you are hearing now will be more your bag. funky music plays. 0riginally we were going for 100% ai generated approach, here we first tried it by training our net on all

of germany's eurovision songs, but it it did not sound broadcast worthy, so instead we flipped it. we said, ok, let us approach this like music producers just using these tools to enhance our workflow. this is another entry. called come together, it was made by the swedish team. all of the machine learning algorithms we have seen are only as smart as the data puts into them. by analysing mountains of existing songs, the idea is to try and learn the fundamental patterns that make up music. we gave the neuron letter a huge amount of data, and what it does is it tries to extract patterns from the data, so it creates overtime new melodies that were not in the datasets, and they are brand—new. twinkly music. but do ai advances like this mean that human composers are at risk of being replaced ? ed newton—rex is a judge in the competition. maybe in a way, we as people do not

want to think that al systems can be musically creative, and i think that is totally fair and totally understandable, but i think what we are saying is that should not be the aim of ai composition. the aim should be to be a tool for musicians, a way of inspiring them, a way of giving them new musical ideas. letting them may be input an idea and seeing what the ai system does with it. this is an ai music competition, but the humans have been an indispensable part of the process. whether that will be true for humans in the future, though, may not be quite as certain. ai eurovision is now on, and we would love you to go and visit the website, listen to the tracks and vote for your favourite. the address is on the screen now. we have had a listen to the competing songs here. what did you think, lara? well, for me, eurovision is all about the theatre, and, of course, that is missing,

which does take quite a lot away. and i thought most of them sounded quite computer—generated, but maybe the idea was to kind of go with that. it really did, didn't they? this was my favourite. let me play it to you. this one is called princesses, and it was one of the belgian entries. here we go. it reminds me a bit of a 60s classic, particularly at the start. double bass strums. good beat to it. yep, yep. so my favourite is from that well—known european country australia. it is uncanny valley. the lyrics are bonkers. "dreams are cheap". "they can leave me crazy". of course they can. and then they start banging on about the power of fire. i want to know which bit of that the ai thought up. anyway, we will play out with this. thank you so much forjoining us on this most unusual of programmes, but hopefully it worked for you. hopefully. you can keep up with the team throughout the week on facebook,

instagram, youtube and twitter at bbc click. see you next week, lara. see you on social media. thanks for watching. see you soon. # 0h. # welcome home. # 0—o—o—oh. # welcome home, welcome home. # oh, oh, oh #. hello there. well, there's another fine and sunny day on tuesday. not quite as chilly but there was a bit more high cloud in the sky in scotland. then it was picked up by the setting sun in stirling, with a fine end to the day here. now, some of the high cloud is pushing southwards now, which means it could well be quite a nice sunrise across some eastern areas as we start off wednesday morning. other than that, it's going to be a chilly start to the day. you can see the skies for many, apart from the high

cloud, staying clear. and that will allow temperatures to dip down, close to orjust below freezing in the countryside, to give some patches of frost up and down the country. an area of high pressure firmly with us then as we get on into wednesday, centred close to the uk — it means there's going to be more fun and dry weather for the vast majority. remember though, there will be a little bit more in the way of high cloud in the sky, which at times will make the sunshine a little on the hazy side. also thicker cloud working in across the northern and western isles. it could bring an odd light shower and some cloudy weather seeping its way southwards across western scotland. just knocking the edge off the temperatures here. otherwise it's a warmer day. temperatures reaching a high of 18 degrees. now, on into thursday, we're going to see some colder air arriving to the far north of the uk but some warmer air arriving across england and wales. so thursday is a day of increasing contrasts. again, there will be some areas of high cloud around, which will make the sunshine rather hazy at times. we could see some showers arriving towards the south—west of england late in the day, although there is some uncertainty about exactly

how many of those are likely to make it down to the ground. and across the north—east of scotland, that's where we've got some cloudy weather, an odd spot of rain, and much cooler conditions but, otherwise, england and wales seeing temperatures into the low 20s. it will feel increasingly warm. for friday's forecast, there is a rather greater threat of seeing some showery bursts of rain, particularly across parts of southern england, perhaps the midlands and wales as well. turning increasingly heavy perhaps later on in the day but, away from that south—west quarter, it's largely dry but still quite a bit of cloud in scotland and we'll start to see those temperatures cooling off around some of the north sea coasts of england as well. come inland, 17 degrees still not bad for birmingham and for london. now, the weekend, quite cloudy for england and wales. there is the prospect of seeing a little bit of rain for some of us. the driest weather probably in scotland, where it will stay dry and bright.

a very warm welcome to bbc news. the latest headlines for viewers in the uk and around the world. i'm mike embley. president trump halts us funding to the world health 0rganization over its handling of the coronavirus pandemic. the reality is that the who failed to adequately obtain, vet, and share information in a timely and transparent fashion. more than one in five deaths in england and wales is linked to coronavirus — the figures show 6,000 more people died than expected at the beginning of april. polling is under way in south korea's parliamentary election. the result is expected to be influenced by the government's handling of the coronavirus crisis.
