ofthe police officers, members of the community, members of his rugby club and they all paint a picture of a man who was part of the community, much loved, much respected, a man with a sense of humour, who engage with a sense of humour, who engage with the community. we had from cressida dick, the head of the metropolitan police, that he was even respected by some of the suspects he checked into the custody suite here. there are a number of investigations under way now. what do we know? the circumstances are that this all happened in the early hours of friday morning. a suspect was arrested on the street on suspicion of carrying class b drugs and ammunition. he would have been given an initial pat—down search at that stage and then was brought here to the custody suite about 215 in the morning and it was as he was undergoing or starting a more thorough search, sergeant ratana

they have had a metal detector, that those shots were fired. police are trying to find out the precise circumstances of what happened. the office for police conduct say they haven't spoken to the police officers who were here. we understand there were a number of them involved in the arrest. they haven't spoken to the officers because they were traumatised by what they witnessed. those interviews will take place in a few days' time but they will have evidence from security cameras and body one footage. obviously they have been trying to find out how on earth that weapon got into the police station, how it was discovered in that initial search, it apparently was concealed of the stay very well. before you go to the weather we will bring you some breaking news concerning the sad death of a six—year—old girl in gosforth in newcastle. we have a statement from northumbria police, who have

confirmed that yesterday just after lunchtime, around 1:15pm, they received a report a child had been struck by a fallen tree at gosforth park school. emergency services attended the scene and the six—year—old girl was taken to hospital. sadly, earliertoday, saturday, they are reporting the young girl, the six—year—old, has passed away. officers are continuing to support the family and officers are with them in this incredibly difficult time. an investigation has been launched with police working in conjunction with the health and safety executive. the sad death of a six—year—old girl in gosforth in newcastle after a tree fell and struck her. whether time, he is darren. for many western parts of the uk today there has been pleasant sunshine, it hasn't been as wind but a different story east where there isa a different story east where there is a lot of cloud this evening and a lot of the rain will be pushing away

to the south—east, moving away overnight with the winds easing a bit but we hang on to the cloud. further west, clearer skies, light bit but we hang on to the cloud. furtherwest, clearerskies, lighta winds, may be a pinch of frost in central scotland southern parts of northern ireland. much milder overnight for eastern england underneath the cloud, temperatures not rising a great deal tomorrow with those cloudy skies continuing although a good deal drier than today. elsewhere much lighter wind, more ina today. elsewhere much lighter wind, more in a way of sunshine, should feel quite pleasant but those winds still quite strong and gusty across the eastern parts of england, gusting a0 miles an hourfor a while, easing down a bit through the afternoon so it won't feel as chilly as it has done today. temperatures in london perhaps up to 16. further west, attempt likely to be higher, across south wales may be 18.

hello, this is bbc news. now we go to click, creating virtual avatars. this week, youtube cracks down on misinformation. nick sneaks up on a robot tractor and a mask wearing exercise has been postponed due to unforeseen circumstances. welcome to click. don't know about you but the weather has turned autumnal here and as expected the restrictions are being tightened up as the numbers rise. there we go, on the way to enter. how are you doing, lara? i've been under the weather this week. not

coronavirus but it got me thinking that if i am ever unwell it would be handy to have a spare version so i've been working on a virtual version of me. we are a technology programme. yes but this is the danger if ever they create a convincing version of us, we are out ofa convincing version of us, we are out of a job. convincing version of us, we are out ofajob. hi, convincing version of us, we are out of ajob. hi, spencer, convincing version of us, we are out ofajob. hi, spencer, i am convincing version of us, we are out of ajob. hi, spencer, i am virtual lara. do you think anyone would notice? what was that? where did that come from? i was created by ai generation platform. it seems anyone can have a virtual them so what do you think? i think that is absolutely incredible! the only thing that didn't for me was lip—synched, your mouth was doing something weird, like you'd just come out of the dentist or something but that... can we bring up the real lara? what they've done, have they reanimated your mouth? it was frightening to see how wonky my mouth is, i've never noticed that

before! the purpose of this as it could be used for corporate training videos where a familiar face or even calling people by their names could be helpful. how did you make it? i had to make a video of me presenting the exact same thing five times. to do this i need to follow their guidelines which included setting rather still, not moving my arms and not getting to animated which for me felt rather unnatural so i was expecting the end result to be strange as a result. once you've made that video, they are able to use it with all your different mouth movements to add whatever sound you've given them making it look as though you are actually saying it. they can do it using one of their voices which means there is the opportunity to give you different accents or different languages. hi spencer, i am the new virtual lara. excellent spanish! thank you!

somebody can tell us more about the purpose of this is the ceo of the company. hello! we've looked at your technology before on the programme and at the moment there is an option of voices available on the platform 01’ of voices available on the platform or you of voices available on the platform 01’ you can of voices available on the platform or you can prerecord your own but how about creating an artificial version of our own voices, will it be possible soon? absolutely. that is the natural next progression of these technologies. we can replicate your image in a believable way and sooi'i your image in a believable way and 5001"! your your image in a believable way and soon your voice as well. the voice technology is kind of there today but it requires a lot of audio to really work. usually the kind of rule is 15—20 hours in a professional recording studio of you reading aloud text. why is it so much harder to do voice than video? well, there are several reasons but one of the reasons is if you think about what a computer sees, then if

you are replicating a video of you in the kind of style you've seen with lara, there is the kind of space of possibilities is quite constrained. you're replicating a video of someone sitting here and they are speaking and you sync their lips and head movements and things like that. if you try to do something like this with a voice, then the training data will be a lot more limited, so let's say even if you have two hours of you talking, that is still a very, very little part of all the things you could possibly say. so could i use your platform to upload a video of anyone, not me, and create a virtual version of them? no. why not? we need written consent from whoever is being uploaded. so everything goes through manual review and we only do custom avatars for corporate clients. so clearly you have protocols in place, but is the very existence of this technology, the fact that all of this is possible, not a pretty big risk in itself, that the wrong people will use it? we have seen these kind

of things happen before. definitely, synthetic media as a whole definitely comes with potential for misuse, that is something that is really important that we address. both from a technical perspective but also from an educational perspective. i think any technology can be used for good and bad, i am not sure i think that deepfakes or video is uniquely different from being able to forge text or images, or tweets, which has been possible for the last 20 years, but it is certainly something we need to be really aware of. thanks victor. so the reality is that making fake videos has become a lot more sophisticated. and we are already all—too—familiar with how false information can cause real harm, and has damaged people's trust in news. and even though most of the conversations have been centred around facebook, youtube has also been a big contributor to the spread of misinformation. now the upcoming us election is going to place even more

emphasis on this issue. and so the bbc‘s specialist disinformation reporter marianna spring has been finding out more. youtube has an incredibly smart algorithm. at least smart enough to make the company a lot of money. more eyeballs on a video and more engagement equals more cash. it's simple. but what is not simple is how potent this combination has become. videos from fringe groups with extreme ideas surfacing to the top and influencing users' views. the pandemic has pushed the issue to new levels, with false information about the coronavirus often finding a much larger audience than trusted sources. as the months have gone on, youtube has become inundated with documentary—style films from pseudoscientists promoting conspiracy theories. this plandemic documentary received millions of views. despite efforts to remove it from youtube, facebook and twitter, users were

constantly re—uploading the clip. and recently demonstraters have taken to the streets in london to promote some of the most popular coronavirus conspiracy theories mainly seen online. a man who would like to remain anonymous got in touch with us after his mum decided to go along. mum had two posters, one read "arrest bill gates for crimes against humanity", the other had a qanon hashtag, "save the children". she was first taken in by coronavirus conspiracy theories on youtube and now she has been radicalised by qanon on there too. it is so hard to have a normal conversation. qanon is a conspiracy theory that suggests president trump is waging a secret war against satanic paedophiles in government, media and business. since the last us election, the social media giants have had a bit of a reckoning. they are all trying to clean up their act to stave off heavy—handed regulation. facebook with its oversight board, twitter with more robust warning labels, and now youtube says it has added a new tool to its arsenal to

combat misinformation. it has partnered up with fact checking sites to warn users if the phrase they are searching has been refuted, and pointing them to information by a trusted source. put simply, it is a tool where when users go to search for a particular topic on youtube, if there happens to be a fact check, these fact checks are generated by third—party publishers, that will trigger in the results of that particular query, right at the top of the query, and it will link out to that fact check, saying whether that particular claim is false, oftentimes fact checking publishers have a rating of that type of claim, that will be displayed as well. this is one of the many tools youtube says it uses to reduce misinformation on the site. but none of these measures seem to be proactive and doing enough to reduce exposure to misleading information. the challenge about misinformation, as you know, on a platform like ours, which is an open platform, we really do value the fact that it's an open platform where there is a diversity of voices, is that with

the changing nature of information around this pandemic, what is the new type of misinformation that might pop up? before there was the conspiracy around 56 and covid, who would have guessed that those two kind of randomly, separate pieces of technology and science would be linked together? well that happened in the course of the pandemic. so we had to adjust very quickly to change our enforcement guidelines. you say that these conspiracy theories are new and evolving, but a number of the ones that are still being promoted on your platform have been around for months. especially in foreign languages, including in russian and hindi, of false conspiracy theories about the origin of the coronavirus or even doubting its existence. for content that might not clearly cross the lines of our policies, we reduce that content in our recommendations. so if it is borderline content in nature, because as i said misinformation can be murky but we still want to reduce the exposure to it.

youtube says it has removed millions of videos containing misinformation from the platform, in many instances before anyone has viewed them at all. but there have been numerous examples of videos promoting false claims and conspiracy theories about coronavirus, especially in foreign languages. and those have stayed online for months, accumulating hundreds of thousands of views. the mozilla foundation behind the firefox browser has decided to act, this week releasing a new extension for both chrome and firefox called regretsreporter. the idea is a user can report any recommended content they find unsavoury. mozilla says this helps crowdsource research into youtube's recommendation problem, and it hopes it can force youtube to become more transparent about how its algorithm works. i think that youtube's algorithm is really one of the most opaque ones out of all the platforms out there, which is why they have a lot more work to do. so youtube has come out with a lot of statistics

like saying they have increased, introduced policy changes that work to decrease recommendations of borderline content by upwards of 70%. but the problem is that there is really no way to verify whether or not this is the case without involving the public, without involving researchers, sociologists, people who have knowledge that goes beyond just the boardrooms of silicon valley, that together we are better able to solve this problem of misinformation surfacing in recommendations. hello, and welcome to the week in tech. this week: us company walmart planned to take a 20% stake in tiktok. donald trump cast doubt on the deal unless they could have total control. microsoft announced the $7.5 billion acquisition of zenimax, behind fallout and

the elder scrolls. xbox says the franchises would be added to the subscription packages. an elon musk reviewed a new battery designed for tesla, which has claimed it will give the compa ny‘s vehicles a 16% greater range. police in the us and europe joined forces in a series of co—ordinated raids against illegal dark web marketplaces. the operation known as disru ptor saw 179 people arrested and the seizure of over 500 kilograms of drugs, as well as 6a guns. could this be the future of flying? aerospace giant airbus has unveiled plans for it hailed as the first commercial zero—emission aircraft. the company said its hydrogen—fueled passenger planes could be in service by 2035. and finally, in ‘if movies have taught me anything, this will end terribly‘ news... a 18—metre tall 25—tonne robot has shown that it can move. the gundam robot based

in yokohama,japan, was initially due to be the centrepiece of a new factory. but the coronavirus outbreak has delayed the opening. around the world, each country has their own social distancing rules. here in the uk, they're constantly updated. but there are a couple which seem set in stone. and that is: to maintain a two—metre distance from others where possible, and to wear a face mask in most indoor spaces. but, let's be honest, not everyone sticks to the rules. so, a number of tech solutions have been brought to market to try and help people stick to the guidelines. let's take a look at a few. ocucon have come up with an artificial intelligence solution that identifies when someone is walking towards the store and counts the number of people entering and exiting. once the maximum occupancy limit is reached, the doors lock and only open up again

once there is more room inside. though it is probably one for the bigger chains, as this solution will cost around £6,000. so, in a bid to make people feel safe enough to go back into stores, even smaller businesses are adopting high—tech solutions. videcon have created a system that can detect whether someone is wearing a mask or not when entering a premise. if they are, great! you can walk on through. and, if not, a screen displays a warning to remind them to put one on before coming in. the a! has trained using thousands of images of people wearing masks, but is still fairly new. so, just how accurate is this? so, as long as that stays green, it's working. and this works again. what if i cover my eyes? hold on. right. let's give it a go. green? green. oh, it didn't do it that time. i am gonna see if i can trick the ai wearing this.

man! i thought i was being smart. i thought by printing this out i could trick it into thinking i was going in without a mask. nah... that's...quite annoying. laughter. nose, mouth, nose, mouth. like that. my days, my days! so, i was able to fool that a couple of times, but the company does admit it has some work to do. we've found the system to be incredibly accurate using a whole host of masks. the mask you're showing me there has a picture of a nose and face on it. if we find there's problem masks, we can very quickly teach the system what that mask is and it will therefore be able to identify it. but this system is still quite expensive, costing about £3,000 to install. but with both solutions we've looked at so far, they can be valuable in another way, too. when members of the public are approached and requested or asked politely to put a mask on, i think that can be quite

a personal thing. they can be hostile in the worst—case scenario. they can be hostile in the worst—case scenario. since we've had the system, it's taken a lot of confrontation out so i would say mental health with the team and customers has been improved. what the outdoors? this temperature sensing helmet is something we featured briefly on the show a few months ago and we've finally been able to get our hands on it. just behind the visor is an augmented reality eyepiece which displays an overlay on what is in front of you telling you the temperature of a person. and if they are over a certain limit it could be an indicator they may have a symptom of covid—19. developed by kc wearable this helmet is primarily used by police forces in china but now also being used internationally to survey areas with a large volume of people. there is something in common with all of these products, may you've

noticed it. all of them were designed before the pandemic, with other users in mind and are now trying to quickly adjust their devices to market them as something to help in the fight against spreading covid—19. there needs to bea spreading covid—19. there needs to be a way to test these products to see if they've been repurposed effectively and that's why were here today at a research event where they will be looking at these distance sensing device to see how well they alert you when you're within someone's to me to proximity and they're doing that by running through three different scenarios. the first is the chat in the kitchen where two people are moving closer to someone standing by the sink to see how quickly the devices go off once they move within two metres of them. second is the walk down the corridor where two people will walk past each other. this is done at different speeds to see if the devices can pick up such a quick passing by. and the third is the close but not close enough to see if

the devices can tell a wall separates the two people in close range and instead won't go off. now these accessories use one of three different kinds of radio waves to detect one another. the well—known bluetooth, the lesser—known ultra wideband used by many tracking devices and are also appearing in smartphones or a combination of both to maximise range. bluetooth devices didn't fare well and failed all the tests. it is a very accurate if the devices are obscured. ultra wideband ones performed very well as its a ccu ra cy ones performed very well as its accuracy is roughly 5—10 centimetres and the combo products did well, too bad all of them failed to the wall scenario which isn't good enough. there is a lot of hype around this and the entry barrier is really low so you're going to find there are a lot of devices pretending to do some things that actually they don't

deliver. proper evaluation of devices and solutions is important. many companies are bringing their solutions to the market and as keen as they are, whether their aim is to sell or help, the most important thing is that it works. that was omar and how interesting was that! now to something else i've been looking forward to. it's only the continuing journey across the australian outback in search of tech! yes, he is back in a field this time in queensland central highlands with some robots for company. plus, a spot of cutting edge a! to look at. we are building autonomous robots and are also a fully fledged farming operation as well so we grow wheat, barley, chickpeas, mung beans, and we run beef cattle as well. we are farmers and we want to change the way we farm. we got bigger and heavier and we are compromising the way we we re

heavier and we are compromising the way we were doing things so we started the farm better. we are up to 27 tonne. the erosion those tracks are making is huge. joshi and andrew realise their traditional practice of compacting the soil too much and in the face of increasing herbicide resistance decided to make their own. and they really went for it. weighing in at a slender 2000 kilos with a 75 horse powered diesel engine, fifth—generation bot november autonomously prowls paddocks on the hunt for invasive weeds. november has 13 different infrared cameras dotted along its back boom and when it drives over weeds it sees them and sprays some herbicide out one of its individual

nozzles. with such precision it can target those hard to kill weeds and i'm told it can cut harmful herbicide usage by up to 98% drastically reducing run—off. it can work day and night, it doesn't need a lunch break and unlike me it is not headed to the pub at the end of its shift. what are these here? these are cameras, three different cameras, and they are actually detecting, building a ground plan out of the machine and any obstacles built up of background planes if there is something that comes up that unexpected, it'll stop for that. we try to feed as much info as we can before it goes out there but this is one of the measures we have in place. so i don't get run over? yes. developing the software on the farm puts is leagues ahead in terms of the practical application of the technology. if we were in the city or somewhere where we would have to test every three or four weeks, there's a delay in the feedback of

there's a delay in the feedback of the software. with the training ground on their doorstep it means developers can rapidly prototype and see their code in a real—life scenario right out in the field. for us, we can write something up and haveit us, we can write something up and have it out on a rabbit within an hour out in the real world within a couple of hours after that. it makes the process faster. we want to get them into the paddock to see how it is actually going to respond to the environment or whatever is in front of it, so every panda can every industry is different. and the bots are customised for every industry. they have a macadamia nut farms, planting cotton, mowing for date—mac farms, and they‘ re planting cotton, mowing for date—mac farms, and they're turning the laser focus to orchards. literally. the technology uses computer vision and looks at each tree and says this tree needs thinning today and this tree needs thinning today and this tree doesn't. the end result will be

better quality for better yields and potentially less chemicals used in the system. and eventually they want to get rid of using chemicals altogether. if we can pluck a weed out or ship it out or microwave it for example, there is lots of opportunities in that area. we are a husband and wife team which is normal in agriculture. a lot of people say how is it to work together! it is what we do. in agriculture you see it all the time so agriculture you see it all the time so it's nothing different for us. agriculture you see it all the time so it's nothing different for uslj was going to say isn't it a pain in the... oh, sometimes! that was nick loving life on the farm! and that's it from us for this week. as ever, you can keep up with the team throughout the week on social media, find us on: youtube, instagram, facebook and twitter at bbc click. seriously, she's already gone and left her virtual self to do the work? honestly. well, from the real me and the not—so—real her,

thanks for watching, and we'll see you soon. bye— bye. theme music. hello there. for many western parts of the uk today there has been some pleasa nt of the uk today there has been some pleasant sunshine, it hasn't been as windy as well. different story for the east. where there is a lot of cloud this evening a lot of the rain we are seeing will be pushing away to the south—east moving away overnight, the winds easing a bit but we hang on to the cloud. further west clearer skies, overnight light winds, quite cold with a pinch of frost in central scotland. much milder overnight for eastern england underneath the cloud. temperatures not rising a great deal during

tomorrow with those cloudy continuing although a good deal drier than today. elsewhere much lighter winds, more in a way way of sunshine, should feel quite pleasant but there is wind still quite strong and gusty across the eastern parts of england, east anglia and the south—east gusting a0 miles an hour for a while, easing down through the afternoon so a while, easing down through the afternoon so it won't feel quite as chilly has done today. temperatures in london up to 16. further west, temperatures are likely to be higher. across south wales may be 18.

this is bbc news the headlines at four. a quarter of the uk population will be under extra lockdown rules — as new measures come into force across parts of northern england and wales over the weekend. it comes as 1,700 students in manchester are told to stay in their halls of residence for 2 weeks after a spike in coronavirus cases. the department of health say they are working to fix a problem with the nhs test and trace app in england and wales after some users were unable to input negative test results. the prime minister borisjohnson urges world leaders to come together to fight against coronavirus — outlining a plan to prevent future pandemics at the un's general assembly. unless we unite and turn our fire against our common foe, we know that
