that will push into wales, northern ireland later in the night. there can see, mist, fog, low cloud are becoming dominant across northern and eastern parts. maybe a of frost across scotland in the morning, but most places frost free to start sunday. a lot more cloud, though, around on remembrance sunday, a few glimpses of sunshine, the best of which in the north to begin with. outbreaks of rain across northern ireland, wales, through parts of the midlands will fade pushing its way erratically northwards and eastwards, on and off rain. most places will spend the bulk of the afternoon dry, particularly the further south you are, and here feeling pleasant once that sunshine‘s out with a high of 16. hello, this is bbc news. the headlines: celebrations have started in pennsylvania wherejoe biden is building on his narrow lead over donald trump. mr biden says he's confident he's going to win the us presidential election and insists he will fight to ensure every vote is counted. the numbers tell us it is clear, tell us a clear and convincing

story, we are going to win this race. joe biden is ahead in the four remaining states that will decide the outcome, where final ballots are still being counted. a week into its second lockdown, france passes 60,000 coronavirus cases in a single day, its highest one—day total since the pandemic began. the uk government has banned all visitors from denmark, due to outbreaks of a mutated form of coronavirus in the country's mink farms which has spread to humans. now, time for our look at all things technological with click. this week, we're looking at your health. ai is listening to your breath. an electric headset is treating depression. and the robots are in theatre.

hey, welcome to click. hope you're doing 0k. now, we're recording this on wednesday. by the time you see it, england will be in its second lockdown, so i've been out to get my emergency pre—lockdown haircut. yes, and i need to get my roots done before midnight so we'd better hurry up! and then i guess over the coming weeks, well, we'll be back to this. i guess so, i guess so. so, although lockdown is an inconvenience for some, and a financial crisis for many, there are those people whose medical conditions make the coronavirus even more dangerous. take cystic fibrosis. now, this is an inherited condition that affects around 11,000 people in the uk. it causes a thick, sticky mucus to build up in the lungs and the digestive system.

recently the cystic fibrosis trust, the university of cambridge, microsoft and the royal papworth hospital have teamed up to create project breathe. it's a remote monitoring platform that uses artificial intelligence. due to the pandemic, the project has sped up. 0riginally it had 97 patients, but by the end of this year, it's expected to have 500. we went to visit sammie read to hear about her experience with the project. sammy was two years old when she was diagnosed with cf and was one of project breathe‘s earliest participants. before i got involved with project breathe, i didn't know what artificial intelligence was. i had no idea. so i use these pieces of equipment to upload all my data automatically to my phone. they then number crunch through the ai system and then they obviously deal

with everything that i have inputted over the last 365 days. trends and that are obviously then analysed and then they are then forwarded onto the relevant person. the equipment is used to monitor key indicators such as lung function and oxygen saturation, which are automatically compiled and tracked via an app. she coughs the ai is used to recognise patterns and predicts any decline in health early. it then alerts an individual when they need to go for a check—up. those living with cf usually have to attend a clinic every six weeks, even if they're well. that results in a huge number of wasted days for people, disrupting their lives and putting them at risk of infection. the artificial intelligence within this monitors my data input and it can see trends

so it can see, for example, when i'm likely to pick up an infection looking forward, when for example, they can see 11 days in advance within the trends that, you know, you are likely to be going downhill so they can pick that up quicker, which means i can treat myself quicker, which means that i'm not then obviously admitted as an inpatient. attending a clinic every six weeks also means that relatively little data is collected, both on the individual and across all of those living with cf. but now, eight or nine pieces of data can be captured at home every day of the year. i'm finding artificial intelligence really interesting. i'm finding it that — how can something so simple as uploading some data mean that it can save me time, it can save the nhs time, it can save my consultant time but it's — everything's just

moving forward and ijust think it's a wonderful thing that we can, you know, obviously input something that takes five minutes that is going to then, you know, increase everyone‘s chances of living longer. that was sammie read. now ai is also being used in a groundbreaking study to try and identify the difference between covid—i9 and other dangerous lung conditions. jen copesta ke been to find out more. the ability to quickly diagnose health conditions is becoming more and more urgent as the coronavirus pandemic continues. there's a backlog of patients waiting for scans. cancer research uk estimates this is currently 3 million people. so doctors are increasingly looking to study how machine—learning algorithms could process large amounts

of data quickly with fewer human resources. at the royal marsden hospital, a study is under way to develop an algorithm that can determine the difference between covid—i9 and the side effects of cancer treatment on a scan. these are things that are often very difficult for the human eye to determine. ok, so this is a patient with coronavirus, covid—i9. essentially, we have some ct scans of the chest, taken a few weeks apart. doctor richard lee is a consultant in respiratory medicine and a champion of early cancer diagnosis at the hospital. so on the left side here, you can see the patient has the two lungs which are usually black in colour. and we have this fluffy, greyer kind of almost ground glass appearance at the bottom of the lung. one of the things we see in covid—i9 is the ground glass change — it suggests infection or inflammation — but the same things can be seen in the context of how

the cancer is behaving, and particularly important is how the treatment itself can cause a very similar change when there is toxicity. a large archive of anonymized clinical images is being used, with approval from the hospital's ethics board. this data can be studied without inconveniencing the patients. expert radiologists can make indications of things that are slightly more like the pattern of covid—i9 or more like the pattern of treatment toxicity. and obviously, this is a new disease and we're trying to understand how much depth we can see in the subtlety and the amount of information we think we can extract. using computer algorithms and analysis we think will be much more able to differentiate those changes, and certainly to do so more quickly when we are under times of strain, such as in a pandemic. one of the patients who gave permission for her scans to be used is sarah ward. sarah was diagnosed with melanoma and has been receiving immunothera py treatment

for the last two years. immunotherapy can cause toxicity to build up in the lungs, which can damage them. i had issues with my lungs at the beginning and i was breathless. i was quite scared, because they said it could damage my lungs and they indicated there was a possibility that i would not be able to go back on the treatment so i was quite relieved when they said that i could go back on it and that there was not any — there wasn't damage to my lungs. this damage can present in a similar way to covid, which is why her scans were selected. so i feel that if that helps future cancer patients and improves the care of cancer, especially in these covid—i9 times, then that's a good thing. i don't mind a machine being used. other ways algorithms are being used to help doctors during the pandemic include identifying covid—positive patients through coughing. the researchers at mit showed how they could use samples

from tens of thousands of coughs to determine whether the cough was covid—related. an algorithm picked up differences indecipherable to the human ear, identifying 98.5% of people who had the virus and were displaying symptoms and 100% of people who were asymptomatic. with no immediate end to the current crisis in sight, finding ways of prioritising treatment and diagnosis using ai will continue to increase. hello and welcome to the week in tech. this was the week that while all eyes were on the us presidential election, gig economy companies like uber, lyft and doordash won a vote in california that means freelance workers such as uber drivers will continue to be classed as contractors, not employees. that same night, voters in maine chose to ban the use of facial recognition by police and city agencies.

if google meet is your video calling app of choice, you may be pleased to know they've just added virtual backgrounds like on zoom, skype and microsoft teams — perfect for hiding your messy kitchen, and just in time for those of us in england going back into lockdown. the makers of the raspberry pi computers have revealed a new model, contained inside a keyboard, inspired by retro machines like the zx spectrum and bbc micro. the company hopes the low—cost device will appeal to families who don't have a computer at home. japanese fashion retailer zozo is giving its spotty body measuring suit another whirl to help people buy clothes that fit online. the zozo suit lets the suit wearer measure their body by standing in front of a smartphone camera. the original was criticised for giving inaccurate readings but zozo says the new suit is much more accurate. 0k, sorry to get this stuck in your head but guess what's become the most—watched video on youtube. # baby shark! it is baby shark, the infuriatingly catchy children's song. it's now been watched more than 7 billion times, overtaking the previous

record holder despacito, the pop hit by luis fonsi. mike is a2. he works in tech and lives in west sussex with his wife and five kids. he's also one of the 264 million people around the world who experience depression. i've had depression for 15 years clinically, living day to day with mood swings and upsetting thoughts like of suicide. you can spend a week where you don't want to get out of bed of a morning. sometimes, when you're depressed, you just don't feel like talking. over the past year, mike has swapped traditional therapy for an app and an electricity—emitting headset. today, only half of patients are accessing the treatment they need, but this set—up could help them get immediate support without even

leaving the house. take these two little jobbers here. you then go — tie up your hair, if you have any — start the headset, and then it connects over bluetooth. i've got a big head so it goes on and it fits me really nicely, actually. a weak current stimulates the part of the brain that's usually less active in those with depression. it's a weaker version of similar treatments already delivered by doctors in clinics. it just tickles, just a little bit. there are pages of advice on sleep, exercise, nutrition and mindfulness. i sit back and relax or i go on the app. female voice: close your eyes and direct your focus into your body. focus on your breathing. the latest thing i did was an attention exercise and it was — it was a video to show me how to — for mindfulness, how

to calm myself and focus on my breathing. male voice: try not to think about these thoughts as distracting. they're actually part of mindfulness practice. most communication on the app goes through a chat bot. this encourages users to stick to sessions, suggest positive actions and record progress. i've done 25 hours of stimulation, it knows that i have done 63 of the chat sessions, and i can see on this treatment programme that there's a downward curve, and a downward curve means that i'm feeling less depressed, which is really important, obviously. when you're on your medication, you don't know how you're doing, but with this treatment, you do. things have changed are fairly fundamental — things like being able to engage with my children more, being able to get into my workshop

and do things that i find relaxing. being out of a depressive mood is life—changing. what it does is that it makes it easier for the brain cells to fire or to discharge, and it's been looked at in thousands of people around the world. i think this is a potential first—line treatment for depression — particularly for people who cannot take antidepressant medication or who might not want to take antidepressant medication or who don't want psychotherapy. that doesn't mean that the treatment comes without risk, though. considering that people might just use this instead of getting — having a proper assessment and getting proper help. how long you can use it for, how much you can — how often you can use it, long—term effects — all of that needs to be looked at some more.

even flow‘s founders in sweden accept their device won't work for everyone. it's the same for all treatments. even as a clinical psychologist, i know that even up to 60% go out of the clinician's office and haven't got an effect from cbt, for example. we know that's true with antidepressants also. flow is now running a clinical study to prove the efficacy of combining the app with the headset, but it's the app they believe will really keep users on course. many people, say, look at the headset and think that this is the new thing but the chat bot is at least as important. the chat bot has many, many functions, so we want to be able to explain to the user that it's important that you follow treatment protocol, we want to be able to remind them about that, to increase the efficacy. but a headset—app combo is not the only option for those

who are struggling. there are many other free clinically approved tools in the nhs apps library. new this year, this one aims to 10— to 18—year—olds improve mental health with its floating ai—driven chat bot. male voice: let's get started and remember, i'm here with you every step of the way. this one uses cognitive behavioural therapy to help those struggling with negative thoughts. whilst these choose—your—own adventure games help install useful emotional fitness skills. apps like these have become increasingly popular in the wake of the coronavirus pandemic. but although they may help, it's important to remember that they don't replace a medical professional. and if you feel that you need some support, you can go on the website

below to see details of the help available. now, while we've been spending more time at home, as well as movies and tv, many of us have been gaming more than we used to. in fact, the click team are having a weekly among us tournament every friday and lara's wiping the floor with us most weeks. but as well as being a distraction from everything, there is one game which has actually been recruiting its community to help research covid—i9. eve 0nline is one of the biggest multiplayer role—playing games out there, with 300,000 monthly players. set in space, you can be anyone — a fighter, a trader, even a pirate. while exploring the universe, players can also engage in a mini game called project discovery where they analyse cell clusters. now, although it'sjust part of the game for them,

they're actually sifting through real world data for researchers who are examining how the coronavirus affects blood cells. it's a gamified version of a scientific technique called flow cytometry which is used to measure physical characteristics of a population of cells or particles. so far, over 171,000 players have completed 47 million tasks which amounts to 36 years of categorising cells. you just look at a plant and you just draw polygons around data. you can sit there, pull it up and start doing it, and i think that was exciting for me — just how approachable it was. you hear about the covid research going on all around the world. a lot of people like you know have had it, or know someone who has had it and just the fact that i can sit here at my desk while waiting for a fleet, doing something that's

going to contribute to helping find out information about covid—19. the data generated by the players accelerates the scientist's ability to determine what's in the blood of covid—19 patients. that information provides an insight into how our bodies react to the virus and how therapies that are being developed interact with both the coronavirus and our immune system. and as players have been so successful at the data classification, they've been given even more complex tasks by the team behind the project. it's really just like citizen science to a tee. we had a giant group of people and we made this fun, we gamified this quite a bit. there are incentives for people to do it that'll boost their game experience, but it's also just the heart and soul of our community as well. these are things that people really enjoy and this really is for the greater good. that was the strength of this project in particular where this came out when everybody in the world was at its height of

being affected by this. voiceover: what we're going to do, guys, is we're gonna sit10k off a target, we're gonna blap it really quick and then we're gonna walk to the run spot. does that make sense? yep. yes. outstanding. standby. and it's notjust about the bonuses for the players. eve online's community is keen to support the scientific effort in the fight against covid—19. that'sjust phenomenal, that i have this opportunity just playing a videogame. and i think that's really kind of what got me into it — is that, i can sit at my desk in the comfort of my home and i can help researchers do something. you know, make a difference. and that's kind of cool. voiceover: and the triage carriers are going tojump — just the triage carriers at first. everyone clear? how brilliant is that? now, we're going to continue with our health theme and talk about surgery, specifically, keyhole surgery. this is something that can be quicker than normal surgery,

it can cause less trauma and it can reduce recovery times. this kind of surgery can be carried out by remote—controlled robots. it's just not that widely available. but paul carter has been to see a new type of robot surgeon that could change that. i'm certainly no stranger to scrubs. you can see the arms moving behind me. they almost look like they're moving independently. this us robot still dominates the market but it's big, it's heavy and costs nearly $2 million a pop. but now there's a new british bot on the block. this also aims to help patients heal quicker by performing complicated medical procedures through just a few access cuts. it turns out, stacking tiny blocks is perfect for surgeons in training. today, only around a third of people who could have keyhole surgery actually get it. it's hoped this small mobile set up will make it more accessible.

one of the differences with this design is that it's modular which also makes a portable. meaning, in theory, even someone like me should be able to move it. surgeons wear 3d glasses to improve depth perception while controllers manipulate wristed arms for greater dexterity and precision. one of the troubles with the big robotic system is it occupies the theatre. when you're not doing robotic surgery, very often the theatre then stands empty. you could fold this up and move it to the theatre next door to colleague number two who wants to use it, honestly, in a few minutes. there's no tremor because the instrument's taken that away from me. anything you can give that reduces the physical strip, it's a win. what's amazing is just the level of movement. it's like you're playing a nintendo switch. it looks like a game but it's not a game, this is, you know, life and death, quite literally.

i can get it exactly where i want it, and it's really relatively effortless. versius has completed more than 1,000 operations this year, rolling into several nhs hospitals, including this one in surrey. it's proving particularly useful amidst the coronavirus pandemic. this operating theatre we're only using because of covid. we wouldn't be able to get the other robot we use into this because it's just too tight. all these modules that you can see are much smaller, we can move them during the operations, you're only constrained by the number of units you can get round the table. but the robotic carts aren't just moved around the one room. ultimately, long—term, it will also enable us to use the same robot between theatres so you can get much more use out of one machine. in future, the devices could even be shared between completely different hospitals. because the units are so small, and they can be packed up, we could put them on a truck

and bring robotic surgery closer to patients rather than have them necessarily travel so far just to one centre. that's notjust convenient, it could help relieve pressure on the nhs. increasing keyhole surgery in this way could help to reduce the risk from coronavirus, not only to patients but to medical staff too. that was paul carter. how amazing was that! i really feel like everything this week has been super interesting! yes, i've enjoyed it! anyway, that is it from us for this week. as ever, throughout the week, you can find us on youtube, instagram, facebook, and twitter at bbc click. thanks for watching and we'll see you soon. bye-bye.

for some of you, it has been foggy and cold but for others sunny. temperatures on the rise and they will rise further. there is an indication of low pressure out of the west of us, clouds are increasing, working northwards. because the winds are coming up from the south, we will see milder air pushed northwards slowly. temperatures will be on the rise but through tonight, still chilly in the north, and we will see dense fog here once again. particular north—east england and central scotland. this evening will be chilly across scotland. temperatures are only four or 5 degrees. staying in double figures in the south tonight. in the channel islands and south—west england, it will turn wetter. across wales and northern

ireland, wales will —— right will push in. felt more of the story in the north—east and across eastern scotland. the greatest chance of frost in scotland, but a little less likely than it has been in recent days. on sunday, low—pressure to the west of us, winds flowing around so winds readily developing. a wet start the summer northern ireland, wales, some further east across the midlands. wetter weather will push northwards, right will come and go, it will stay grey and murky in north—eastern parts of england and in central and eastern scotland. brightening up in the south and in northern ireland and feeling pleasa nt northern ireland and feeling pleasant where the sun is out. into the evening, shamus returned towards the evening, shamus returned towards the channel islands, south—west england and wales. low—pressure to the west of us so a southerly flow and across western areas, likely to see outbreaks of rain through the

night into monday. i don't start to the new week across western areas, in the east, cloudy but optimistic, the club will fill and break at times so we will have sunny spells. downpours in wales in the south—west. temperatures above where they should be for this time of year. through the rest of the weekend, low—pressure remains to the west but it turns windier through mid week, rain at times across western areas, some eastern areas staying predominantly dry. see you soon.

this is bbc news live from washington and london. it's been five days since the united states went to the polls and we still don't have a result. but the key state of pennsylvania, wherejoe biden is currently in the lead, is due to give an update on the numbers. the eyes of the world are on election counters in the state. ifjoe biden manages to secure victory in pennsylvania — he wins the white house. joe biden has been calling for calm and unity — and says he'll soon have a "mandate for action". we don't have the final declaration of victory yet. the numbers tell us it's clear, tell us a clear and convincing story. we're going to win this race. meanwhile donald trump continues to allege fraud
