on public transport. now on bbc news it's time for click. this week: can taking your temperature stop the spread of coronavirus? or will genetics be the answer? or maybe you're just trying to drown out the noise. shall i, sean tighe, shallow, sean tighe? maybe not just shall i, sean tighe, shallow, sean tighe? maybe notjust now. welcome, hope you're well, lara is online too, how are you? i'm good thanks, i tried to edit out my roots before posting a picture on social media yesterday. didn't work, had to give up. i've got something to cover up that hair if you're interested, take a look at this. goodness, that looks dramatic. it is a thermal imaging helmet. the idea is it can quickly scream people to check for fever, it is already being used in china but the company now says they are talking to governance and police forces across the uk, europe and the middle east. it looks quite menacing but impressive if it does the job. yeah, and around the world companies and governments are looking at testing people's temperatures to try and stop those who might —— spot those who might have covid—i9. vodafone is not a company that is rolling out thermal imaging with a camera that can scan up to eight people at a time. they say it is accurate to within 0.3 celsius. the question is low, how useful is reading people's temperatures in stopping the spread of coronavirus? people have variable core body temperatures. so it ranges between 36.5 to 37.5, but there is some variability here. so that data itself may not be that useful. second, there are an increasing amount of evidence showing that... a large numberof amount of evidence showing that... a large number of people are asymptomatic, so even if you do not develop a fever, then you can still go on to infect others. the most pa rt go on to infect others. the most part these days especially i would imagine most people are feeling ill would... put their hand up first and say "i'm not feeling well", or there is something wrong, and they wouldn't try to fool the advice for example by taking ib probe and or paracetamol which would bring the temperature down anyway if it was only slightly elevated. so the practical utility of this idea seems to me rather limited. but vodafone feels it is still worthwhile. it is very possible to have false positives, and to miss people coming through, however we think we will catch identify enough people that it is still a valuable tool to add to out is still a valuable tool to add to our toolkit for creating a safe working environment while we wait for a vaccine to covid—19. working environment while we wait for a vaccine to covid-19. so instead of just taking for a vaccine to covid-19. so instead ofjust taking a one—off temperature measurement, you could look at taking continuous ones, and even add data from other vital signs too. in fact, that'sjust even add data from other vital signs too. in fact, that's just what this trial is doing. election sign a principality with a population of only 38,000, —— election sign, trailing a programme to fitted system — citizens with biometric bracelets to attract potential cases of covid—i9 in real—time. —— liechtenstein. we tried to find a signature of this disease, by measuring parameters of the human body that could give us an early indication if there is a second wave coming. the bracelet measures the heart rate, the skin temperature and some other parameters that can be easily measured on the wrist. but these bracelets are not a new product and actually have a surprising origin. it is a solution for couples who are trying to get pregnant. through the device we are measuring different physiological parameters and based on those physiological parameters we can detect the fertile window and then when covid started to come in we realised the combination of parameters you are measuring could be basically uniquely suited to look at covid and basically monitoring the infection. and we have a couple of other countries and larger products that are also interested, so we products that are also interested, so we might make this study part of a larger study in the end, then we would roll out europewide. however the rollout of biometric bracelets across europe may not be straightforward. health data is particularly sensitive data, so it has a higher level of protection, and you can only process it on a member state basis if you have a strong legal basis provided by law to do that, so it might even be possible that some eu laws would need to adapt to allow the processing of that data. and in belgium there is a very different type of wristband being introduced at the port of antwerp. when corona started, we had this idea where we said hey, wait a minute, we already do measuring between typically a device and a machine, couldn't we just measure the distance between two devices? now we can also provide social distancing capabilities using the same technology, and the wearer gets a vibration when he or she comes to close, they need to step back to get out of the dangerous zone. the bracelets could also be activated for contact tracing, but privacy is an objection. prior to covid—19 everybody thought "my privacy is the starting point of everything". that is not really the case any longer if you have to make sure that everybody stays healthy, right? however the introduction of this technology has worried trade union stop you have to understand how unions work and think.“ union stop you have to understand how unions work and think. if they do not fully understand what this is asa do not fully understand what this is as a piece of technology and what it provides and what the benefits are for their provides and what the benefits are fortheir members, provides and what the benefits are for their members, they will object by definition. and i think that is the mistake some of the companies made, they said it is called technology, we will implement it without taking the time to explain what this is for, and what the benefits are. across the world companies are recognising that their products could be repurposed in the battle against covid—i9. however as governments increasingly look to technology as a solution, ethical and legal boundaries are starting to be tested. hello and welcome to the week in tech. it was the week that robots we re tech. it was the week that robots were being developed to test temperatures in waiting rooms in sweden. a new quadruped robot dog wasn't available to buy a chinese company, and full—bodied disinfection pods were trialed in hong kong airport. this booth has an antimicrobial coating and sprays passengers for a0 seconds with a sanitising mist. it was also the week that an engineer and senior vice president at amazon made a million—dollar decision to quit his job over allegations of unsafe factory conditions. tim bray said workers had been fired for circulating a petition about working conditions. amazon says employees we re conditions. amazon says employees were dismissed for violating internal practices. drone air corridors will be created for remote regions of the uk, allowing for co nta ctless regions of the uk, allowing for contactless deliveries of essential items. the relaxed flying rules with the designated zones where drone operators can fly out of the line of sight if they meet safety standards. nasa announced it was teaming up with tom cruise to make a film about the international space station. but wouldn't comment on speculation the actor may be headed into orbit. nasa says more details on the film will be revealed at the appropriate time. and finally robots seem to be lending a helping hand all over the place these days, and grocery shopping is no exception. this robot called second hands is funded by the eu. it has been designed by a consortium of universities and online grocery —— and online grocery retailer. his purpose is taking other menial tasks and providing a second pair of hands for workers. at times during this lockdown it has felt like life might never be the same again. the stress of financial uncertainty coupled with the

talk about the latest research into the virus. and for that, we have to go to iceland. back in 2013 we went to iceland to accompany called decode genetics, who were doing research on what is a pretty unusual country. iceland has a record of its people's ancestry going back thousand years. and therefore it has some idea of who she has genes with who. iceland has also been donating blood to the company for years, which is then deep frozen in this blood bank, so it can be used for future research into what genes may make people resistant or susceptible to certain diseases. and now that is paying off in spades. i spoke to the direct of decode earlier and he told me that having sequenced the genes of half the population, he has had a massive head start in trying to work out why the coronavirus affects some people worse than others. this team has been working together for a century and it seems like everything else we have done, feels like merely a preparation for this. we have an enormous amount of data on the people who got in fact did. we are ina people who got in fact did. we are in a privileged position to look at the genetics of the patients and see how the genetics influences the probability of getting infected and the probability of getting seriously ill when you become infected. decode has now tested nearly 1a% of the population for the coronavirus, the highest in any country. that has really informed our understanding of covid—19. for example he says that countries —— contrary to some reports it seems that nearly eve ryo ne reports it seems that nearly everyone who has the disease does eventually display symptoms. and the race is now on to understand why those symptoms arrange so widely from the very mild to the very severe. is it because they have previously quarter different coronavirus and develop some immunity? or is it to do with different strains of the viruses itself? viruses naturally mutate as they travel from one person to another, and as this one has spread, it has morphed into many different strains that can be identified from its genetic data, and which are being shared by scientists across the world. what is not known at the moment is whether some strains are more harmful than others. when viruses mutate they usually mutate to become more infectious and less harmful. because the evolutionary goal of the virus is to go as widely as possible, to become as many as possible. and if the virus causes a serious disease, then it limits the transmission because the person who becomes seriously you won't move around spread the virus. but this virus has found an advantage because most people are marginally infected they can run around and spread the virus all over the place but then there are the few unfortunate, so this virus has the best of both worlds it can spread widely and it can kill. what's also fascinating is that because the virus has mutated as it is travelled across the world, is possible for geneticists to examine a patient and tell them the route that their infection took as it travelled from china. in the us, for example, the virus first arrived on the west coast directly from china. but meanwhile, another strain was making its way across europe and it arrived in new york in the middle of march and that was the strain that eventually came to dominate the country, probably because new york is the gateway most americans use to come back home. and while italy seemed to be the epicentre of the european rate, something else was going unnoticed. when the authorities were focusing on people coming from ski vacations in the alps, the virus was clearly sneaking into the country from other countries such as great britain and it's absolutely clear that very early in the epidemic, the virus was widely spread in greater society because a very significant proportion of the cases in iceland came to iceland from those who were travelling from great britain. despite everything, iceland is now starting to recover from the epidemic. it's come through with very few deaths and without the com plete very few deaths and without the complete lockdown that many countries have enforced. this, says doctor stevenson, is because with widespread testing, the country could quickly find those who are infected, tracy they'd been in contact with and then just isolate those people, stopping the epidemic before it got out of control. some of course would say that iceland has had it relatively easy with its small population and remote location. with these kind of measures including this massively manually intensive contact tracing work in bigger countries like the uk? listen to me, there is no alibi in your size. you could use exactly the same methods we have used and i think you could be as effective as just as long as there is a number of resources to do it. yes, in great britain, you have a lot more people who are infected because your population size is incredibly much larger than ours but you have also more people to do the work. i think what is amazing when you look at this epidemic, the two most resourceful countries in the world really, the united kingdom and the united states, that they were com pletely united states, that they were completely unprepared for this. this has been a demonstration of how preparation and early action is saved lives. but it's also a demonstration of how far technology has come to be able to crunch the enormous amount of data that is now spotting needles in genetic haystacks. i think that what this epidemic is showing is how incredibly powerful it is to be able to bring together large amounts of information, bring it together and mine it effectively. been able to do this 20 years ago. really interesting stuff. i know, let's hope they and other scientists keep making those break bruce. let's hope so. now, a lot of us are working from home at the moment and as well as trying to perfect video calls, a lot of us are having to put up calls, a lot of us are having to put up with things like this. dog barks. or this... alarm rings. yeah, i'm often trying to compete with the washing machine's fast spin cycle, i have to say! well chris fox has been trying to find ways to be heard above the background noise. today, i'm on a mission to make as much noise as possible to see whether machine—learning can clean up ouraudio. you might have seen online, a lot of gamers are really excited that nvidia, the graphics card maker, is testing some noise cancelling technology. it's called rtx voice, and to try it out, i have a professional microphone here and a high—end gaming laptop with an nvidia rtx graphics card. and on this side, i have an ordinary laptop running some software called crisp, which says it can do the same thing without the expensive graphics card. the first test is a noisy city apartment. i've left the doors open so we can hear the trains going past. the washing machine is on and, for good measure, this speaker is blasting out the sound of a dog barking. ok, i can heara train going past now. so let's turn on the noise cancellation... and what nvidia says it's doing here is using al on the graphics card on a bit of spare capacity you may not be using while gaming to do the noise cancellation. ok, we have a train going past. so, same experiment again — let's turn on the noise cancellation — there's the dog. and how does the laptop fare without the graphics card? this is just a software ai running on an ordinary laptop. next, we will test in a coffee shop. and since i can't go to a real one, i'm playing crowd noise from this speaker, we are using the coffee machine and playing some music from the speaker — all while i read the blurb on claire from steps' autobiography. "claire richards has been an extraordinary roller coaster journey since shejoined steps at 19. after the highs of chart—topping success and the fame that brought, her life hit rock bottom when she left the band. but she fought her way back to create a whole new career in television, finding her inner strength along the way. now she's finally ready to bare it all." round three is total chaos. i'm using a hair dryer and a vacuum cleaner, and there's an alarm going off — all while i read the introduction to the bbc‘s royal charter. "royal charter — for the continuance of the british broadcasting corporation. elizabeth ii, by the grace of god of the united kingdom of great britain and northern ireland..." "royal charter — the continuance of the british broadcasting corporation. elizabeth ii, by the grace of god of the united kingdom of great britain and northern ireland..." well, let's talk to davit baghdasaryan from crisp. my first question is, are you using your noise—cancelling tech? because we will be listening for every bit of background noise. yeah, absolutely, it is always turned on on my laptop. but let me clap and demonstrate. you won't hear anything. now we have thrown a lot at the software today, and it did a really good job — although with some of the louder noises, it did make the voice sound a bit processed. is that something you're working on? we have a number of technologies we are working on right now. and at some point, it's going to start adapting to your voice. and it'll be, like, way more amazing than this demo, actually. now both crisp and rtx voice work really well on a laptop with pretty much any video calling app you could want. but you are much more limited on android and ios smartphones. so are you hoping to partner with individual apps? we are doing those very strategically. we are very careful who we are partnering with. we did partner with discord, for example, and now crisp is powering 200 million users when they do, like, voice communication. so we think that was a great partnership and we are very proud of that. i've really thrown a lot at both of these systems today, using deliberate background noise. but both of them have done a pretty good job of cleaning it up, even under extreme circumstances. now nvidia is keen to point out that its system is just a test at the moment. but for gamers who already have those high—end rtx graphics cards, it is a nice extra feature to have and should stop annoying background noise getting into your voice chat when gaming online. and for everybody else, software like crisp can help clean up our voice calls and video calls if you can't convince your housemates to be quiet. chris fox, coming through loud and clear! thanks for being the lara. thanks are being there again. my pleasure. all week, you can keep track of the tea m all week, you can keep track of the team on youtube, instagram, facebook and twitter at bbc click. i tell you what, if i'm brave enough, i might even put the trim on line. don't hold me to it. i tell you what, why don't you send out send us photos of your lockdown how cut disasters. we will see you soon. but by. hello. there are lots of weather changes on the way as we go through the rest of this weekend. still some warmth in the day ahead, but it will be turning colder in northern scotland and much colder elsewhere across the uk by sunday. and windier as well. now, what's going on? cold air lurking close to northern scotland saturday night into sunday will surge south. not a huge amount of rain at least towards england and wales, and with that cold air, a stronger wind coming down from the north or north—east as well. we start saturday with temperatures well above freezing, a lot of dry weather around, but in that colder air we have a weather system near to northern scotland and that will bring the rain heavier and more widespread across northern scotland during the day with a strengthening wind. elsewhere in scotland and northern ireland, sunny spells, one or two showers. we could see a few heavy and thundery showers developing through parts of wales, northern england, the midlands and lincolnshire into the afternoon. across east anglia and southern england, largely sunny, temperatures could be as high as 25 degrees celsius, just 9 or 10 degrees in northern scotland with the rain. now, we know the cold air is going to win out through the weekend. this is the process overnight and into sunday morning. by the way, channel islands, maybe close to the south coast of england, there could be a few heavy showers. but it's wet weather coming south through scotland and northern ireland with the colder air going into sunday morning. look how mild it is, though, to start sunday in the south, where there'll still be some early sunshine around. now, there could be some snow following the cold air in scotland to start off on sunday, a few wintry showers around as well. cloud, not a huge amount of rain left as the weather system works south across england and wales, introducing the colder air on sunday. for all, much windier as well. strong, gusty north—northeast winds, 35—a5 mph or so, at their strongest along these north sea coasts. just 7—9 degrees celsius, temperatures 10—15 degrees colder by sunday compared with saturday. on monday morning, a frost for many of us to start the day, so gardeners and growers, take note of that. it's high pressure close by into next week. that does mean a lot of dry weather, but still the air coming down from a chilly direction. and the wind will gradually ease as the week goes on. for next week, high pressure, a lot of dry weather, frosty night at first, wind easing. becomes a little bit less chilly eventually. welcome to bbc news, i'm lewis vaughan jones. our top stories: marking the 75th anniversary of victory in europe. the queen leads tributes to past sacrifices as the uk remains under lockdown. many people laid down their lives in that terrible conflict. they fought so we could live in peace, at home and abroad. bagpipes skirl. on a day that should have been filled with parades and street parties, prince charles holds a moving tribute at his family's balmoral estate. the uk government is expected to impose a two—week quarantine on almost everyone entering the uk from the end of the month. spain approves a bigger relaxation of the lockdown, as small firms are allowed to serve customers again,
