bagpipes. prince charles leads the uk in remembrance, as communities fell silent for two minutes to mark the 75th anniversary of the end of the second world war in europe. the queen will address the uk this evening. donald trump lays a wreath at the war memorial in washington, and isjoined by several second world war veterans. in the united states, 20 million jobs are lost as the coronavirus pushes up unemployment to its highest since the great depression of the 1930s. and as the uk government decides whether to ease some lockdown measures — from monday, people in wales will be allowed to exercise outside more than once a day. now on bbc news,

it's time for click. shall i, shan‘t i, shall i, shan‘t i? maybe not just now. gotta happen soon, though, hasn't it? welcome, hope you're well. laura is online too. how are you, mate? i'm good, thanks! i tried to edit out my roots before posting a picture on social media yesterday. laughter. didn't work — had to give up! your hair is going to get crazy soon, isn't it? listen, i've got something to cover up that hair if you're interested. take a look at this. 0h goodness, that looks a bit dramatic! yeah, it is a thermal imaging helmet. now the idea is it can quickly

screen people to check for fever. it's already being used in china, and the company now says they are talking to governments and police forces across the uk, europe, and the middle east. it looks quite menacing — but impressive if it does the job. yes, and around the world, companies and governments are looking at testing people's temperatures to try and spot those who might have covid—i9. vodafone is another company that is rolling out thermal imaging with a camera which can scan up to eight people at a time. they say it is accurate to within 0.3 celsius. but the question is — how useful is reading people's temperatures in stopping the spread of the coronavirus? people have variable core body temperatures. so the range is between 36.5—375 celsius. but there is some variability here, so that data itself might not be that useful. second, there are an increasing

amount of evidence showing that a larger number of people are asymptomatic. so even if you do not develop a fever, then you can still go on to infect others. it is very possible to have false positives and to miss people coming through. however, we think we will catch or identify enough people that it is still a valuable tool to add to our toolkit for creating a safer working environment while we wait for a vaccine for 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 sites too. in fact, that's just what this trial is doing. lichtenstein, a principality with a population of only 38,000, is piloting a programme to fit its citizens with biometric bracelets in a drive to track potential cases of covid—i9

in real time. we tried to find, like, kind of 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 heartbeat, 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's really a solution for couples who are trying to get pregnant. so through the device, you are measuring different physiological parameters, and based on those physiological parameters, we can detect the fertile window. then when covid started to arrive, we realised that the combination of the parameters that you are measuring could be — basically they were uniquely suited

to look at covid and basically monitoring the infection. and we have a couple of other countries and larger projects that are also interested, so it might make this study part of a larger study in the end, and it would rule out europe—wide. however, the roll—out of biometric bracelets across europe may not be straightforward. health data is particularly sensitive data. so it has a higher level of protection. you can only process it on a regular basis if you have a strong legal basis for abiding by law to do that. so it might even be possible that some eu laws would need to adopt a new law allowing for the processing of the 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 a device and a machine. couldn't we just measure between two devices?" now we can also provide social distancing capabilities using the same technology, where 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 bracelet 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." well, that's not really the case any more if you have to make sure that everybody stays healthy, right? however, the introduction of this technology has worried trade unions. you have to understand how unions work and think. and if they do not fully understand

what this is as a piece of technology and what it provides, and where the benefits are fortheir members, they object by definition, right? and i think that is a mistake that some of the companies make, saying, "you cannot implement this without taking the time to explain what this is for and what the benefits are." across the world, companies are recognising that their products can 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. now a lot of us are, of course, working from home at the moment, and as well as trying to perfect your background for video 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 fastest 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 our audio. 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 expense 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 dog barking. ok, i can heara train going past now. so let's turn on the

noise cancellation... and what nvidia says it is 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. 0k, 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 the speaker, we are using the coffee 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 — 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 that you want. but you are much more limited on android and i0s smartphones. so are you hoping to partner with individual apps? we are doing those very strategically. we are very careful with 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 higher end rtx graphics cards, it is a nice extra feature to have and should stop annoying background was getting into your voice chat when gaming online. and for everybody else, software like crisp can 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! and that's it for the short cut of click this week. please do try to check out the full length version, there's so much more great stuff in there — and you will find that on iplayer. you'll find us on social media throughout the week, youtube, facebook, instagram, and twitter at @bbcclick. thanks for watching, and we will see you soon.

more now on today's ve day celebrations — and the coronavirus pandemic has meant no large parties or parades have been allowed. instead, people were encouraged to hold tea parties in their homes, or have socially distanced street parties. phil mackie reports. they're getting the bunting ready and the flags are out. today punishment commemorations at this home in kenilworth are particular poignant for this man. a lancaster born pilot who survived missions. the highest of any of the command station, because we used on every bombing raid that went out. on your 13th operation, you got a few days leave. and when i came back, all the

senior staff were gone. raf flyers fly through a wall of heavy flak. rusty flu during the battle of berlin at the end of 1943. when barely half the planes that set out on the raid came back. he flew his last mission on d—day and spent the rest of the war as a pilot instructor. when v—e day came around, he and his crew where it is stated in. we had to go find a pub somewhere, so my fiance and seven of the lads and their girls walk across the lads and their girls walk across the fields across a little stream to the fields across a little stream to the normans and arms on the main road north. we drank that dry. here we are, 75 years later. how do you feel now looking back? you realise how plenty lucky you are. an awful

lot of luck. russ is a living connection for later generations to another great national emergency. the silence they observed this morning was a time to remember the greatest of sacrifices. phil mackey, bbc news, kenilworth. the soprano katherinejenkins has recorded a concert behind closed doors at the royal albert hall to mark the 75th anniversary of ve day. here's a little taster of her singing wartime classics. # i may be right, i may be wrong # but i'm perfectly willing to swear # that when you turned and smiled at me # a nightingale sang in berkeley square... well earlier today, my colleague reeta chakra barti spoke to katherinejenkins. royal albert hall is my favourite venue in the entire world. and i actually found the performance quite emotional.

you know, throughout singing, ijust kept thinking of hopefully we would be joined by people across the nations from their homes who will be keeping me company in singing along, i hope. but usually — and i'm sure they will — but usually, of course, you can see and feel your audience, you're performing to them. so it must take something to perform in a completely empty hall? yes, but that's why i was so thrilled when the royal albert hall invited me to come do this. i was actually meant to be presenting the 75th anniversary concert this evening, which understandably was postponed until later in the year. and i think it isjust so important that we, you know, get to celebrate this day in the very best way that we can, given the circumstances. so to be asked to do something that's never been done in its 150 year history was a massive honour. and i spent the last few weeks doing facebook live concerts to phones where i got used to singing

without any feedback or applause, or anything. so that's been my experience with lockdown. we often talk about the men who went off to fight. but let's not forget that more than 250,000 british women also signed up for military service in world war ii. graham satchell caught up with two of them. nice to meet you. yes, indeed. perhaps we'll meet one day. betty and molly, two quite remarkable women. i shall be 97 this time next week. 97? lam 102. you're a chicken! archive: hundreds of the first girl conscripts that this country has ever known arrived with volunteers at a depot to be welcomed into the ranks of the ats. more than a quarter of a million womenjoined the ats in the second world war. archive: in less time

than it takes to tell, the 21s and unders have said goodbye to civvy clothes and are donning the uniform of the ats. they're in the army now. molly is thought to be the oldest—surviving female veteran. it takes a small army of helpers to put all her medals on. i was a supervisor in woolworths, and i wanted to join the army, so ijoined up when i was 22. i was a sergeant major within nine months. wow! yeah. ijust went zoom, straight to the top. this is afterwards. that's me there. ah! look at that uniform. incredible. you look so smart, betty. thank you. betty webb spoke german, so when she signed up she was interviewed by military intelligence and sent to bletchley park. what did you do when you got there? oh, well, to start with, read and signed the official secrets act, which was pretty frightening, because i wasn't expecting it.

and it was a fairly formidable document, as you can imagine. what happened at bletchley park was kept secret for decades. it was home to the codebreakers, and credited with shortening the war and saving countless lives. betty'sjob, to register the signals coming in from all over the world. it was a mammoth task for the codebreakers to make sense of it all. another group of people would decide where the messages were to go, either direct to the field or winston churchill. archive: the prime minister, accompanied by mrs churchill, visits anti—aircraft guncraft, which are tackling flying bombs. did you meet winston? only in inspections. not to... ..not to be pally with. didn't come to dances or anything like that. at the height of the blitz, molly's job was to control a battery of anti—aircraft guns, stationed in richmond park. i had to tell them what fuse to put

in the guns and to stand by and stand by and stand by and fire! when i said "fire", that was when they had to let them all go. i just wanted to ask you whether it was scary, molly, when you were doing thatjob? no, not a bit. i loved it. i was all bustle. did you feel comfortable telling men what to do? oh, yes, they had to do as i told them, or else they'd get put in the cookhouse peeling the spuds! laughter. did you quite enjoy that? yes. don't mess with molly! we may allow ourselves a brief period of rejoicing. the end of the war in europe, ve day, 75 years ago today. as soon as the news came through, bletchley went slightly mad and i went up to london with others,

on the train, and we milled around in london, everybody singing and dancing and drinking. and there were so many people there, you didn't have to consciously walk, you were just pulled along by the crowd. well, it was total elation, of course, and relief after all the problems. a lot of sadness for those who'd lost people. but, at the same time, a great deal ofjoy. 0n ve day, molly was still on the front line, in nuremberg. shortly afterwards she married her husband bernard. they were the first couple to marry in occupied germany. keep yourself well. yes, and you. talk to you soon. talk to you again. betty and molly, just two of the extraordinary, remarkable women who helped to win the war. she is lovely, isn't she? yes. graham satchell, bbc news. across the country, people have been

remembering the sacrifices made during world war two and celebrating the freedom that was won for us all. our home editor mark easton reports from essex. the essex village of dedham is chocolate box britain, symbolising the way of life defended in the war and the freedom celebrated on ve day. 75 years on, and locked—down dedham is looking to its oldest resident to rekindle the spirit that saw the country through some of its darkest days. 99—year—old marjorie west, like captain tom moore before her, is raising money for the health service by walking up and down her garden path — 5,000 metres completed today. i'm thinking about the people that gave up their lives in the war and thinking about the captain that did his walk, and i must try and do the same. a toast to marjorie west. marjorie is part of the greatest generation, renowned

for their sense of duty, resilience and humility. you accepted it and you just hoped that it would help win the war. because i love my country. after her first husband, a spitfire pilot, was killed in 1942, marjorie signed up for the wrens. the sailor girls are proud to belong to the feminine side of the senior service. i knew i had to go and help. ifelt he had given his life and i still had a life, so i could use it. marjorie ended up in the top secret command centre planning for d—day. she speaks french. she saw it as a job. president macron saw it as deserving of france's highest order of merit, legion d'honneur. you felt you had to do what you were given to do and peace would come. let the flags fly for ve day, for courage,

for sacrifice and for marjorie. all: we support marjorie. she's never given up. she's just really generous and compassionate in the nhs and what they're doing at the moment. cheering. social distancing has brought communities closer — the restrictions on liberty an emphatic reminder of what freedom means. cheers. cheers to the generation that channelled the wickedness of war to imagine goodness in peace, to build up our beloved national health service. it comes out of the wartime spirit of sacrifice and actually putting other people first. so, in a way, when we clap on thursday, we also clap the vision of that generation? yes, absolutely right. village shopkeepers told me how the qualities of the wartime generation still shine through. it wasn't that generation that was doing the panic buying. for example, we sell two chickens for £7, that's the offer —

they would buy one and say, "i must leave one for someone else." it's resilience, it's mental fortitude that they bring and it also just helps uplift the community as well. three generations in one household paused to give thanks for war‘s and. mary, 98, who was there, her daughter and grandchildren. thinking about the sort of freedoms that, you know, are being curtailed at the moment, i hope it's making us sort of more appreciative of the kind of things that, you know, your generation really had to fight for. it wasn't as bad as this! ve day was a comma, not a full stop. the hardship would continue long after the guns fell quiet. but it is a moment to remember the spirit of a generation that saw it through. even if you did a small thing, it was something. maybe that's a message for now, too. yes.
