as he inches closer to victory after pushing ahead of donald trump in two crucial states. overall, mr biden needsjust 17 more electoral college votes in order to reach the magic number of 270. mr biden is increasing his margin over the president in arizona but a recount has been announced in georgia, wherejoe biden‘s lead over donald trump is more than 4,000 votes. the mayor of atlanta has said she is positive that the results will stand. in pennsylvania, joe biden has built up a lead of nearly 20,000 votes over donald trump in the crucial count there. however, the city's mayor says trump must admit defeat. pennsylvania is of critical importance to both candidates as it's worth 20 electoral college votes. now on bbc news, click.

this week: we're looking at your health. ai is listening to your health. ai is listening to your breath. an electric headset is treating depression. and the robots are in theatre. hey, welcome to click. i hope you are doing 0k. hey, welcome to click. i hope you are doing ok. we are recording this on wednesday. by the time you see it england will be in its second lockdown so will be in its second lockdown soi will be in its second lockdown so i have been out to get my emergency pre—lockdown haircut. yes, andi emergency pre—lockdown haircut. yes, and i need to get my roots done before midnight so we better hurry up, and then i

guess over the coming weeks, well, we will 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 conditions 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 pa pworth hospital cambridge, microsoft and the royal papworth hospital have teamed up to create project trees. it is a remote monitoring platform that creates —— uses artificial intelligence and due to the pandemic the project has split up pandemic the project has split up and originally it had 97 patients by the end of this year it is expected to have 500 —— project breathe. year it is expected to have 500 -- project breathe. we went to visit sammy 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, idid not involved with project breathe, i did not know what artificial intelligence was. i had no idea. so i use these pieces of equipment to upload all of 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 la st that i have inputted over the last 365 days. trends and that are obviously then analysed and then ai then forwarded onto releva nt then ai then forwarded onto 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. 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 are 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 , pick up an infection looking forward, when for example va ca i'icy forward, when for example vacancy 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 collect, 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. lam finding at home every day of the year. i am finding artificial intelligence really interesting. i intelligence really interesting. lam intelligence really interesting. i am 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 is everything just moving forward and i just it is everything just moving forward and ijust think it is 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—19 and other dangerous lung

conditions. janko mistake been to find out more. ——jen copesta ke. to find out more. ——jen copestake. the ability to quickly diagnose health conditions is becoming more and more urgent as the coronavirus pandemic continues. there is a backlog of patients waiting for scans was not 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 master hospital a study is under way to develop an algorithm that can determine the difference between covid—19 and the side effects of cancer treatment on a scan. these are things that are often very difficult for the human eye to determine. 0k, difficult for the human eye to determine. ok, so this is a patient with coronavirus. covid—19. 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 i usually black in colour and we have this fluffy, grey kind of almost ground glass appearance at the bottom of the lung. 0ne glass appearance at the bottom of the lung. one of the things we see in covid—19 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, particularly important is how the treatment itself can cause a very similar change and whether it 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 radiologist can make indications of things that are slightly more like the pattern of covid—19 or more like the pattern of treatment toxicity and obviously this is a new disease and we are 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 immuno therapy treatment for the last two years. immuno therapy 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 treatments i was quite relieved when they said that i could go back on it and that there was not any does there was no damage to my lungs. this damage can present in a similar way to

covid which is why her scans we re covid which is why her scans were selected. so i feel that if that helps future cancer patients, and improve the care of cancer, especially in these covid—19 times, then that is 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 covert —related. an algorithm pick up differences indecipherable to the human ear, identifying 98.5% of people who have the virus and were displaying symptoms and 100% of people who we re symptoms and 100% of people who were asymptomatic. with no immediate end to the current crisis insight, finding ways of prioritising treatment and diagnosis using ai will continue to increase. —— in

clinically, irving day with swings and upsetting thoughts like suicide. you can spend a week where you don't want to get out of bed in the morning and sometimes when you are depressed you just don't feel like talking. over the past year, mike is what 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 the house. take these two littlejobbers here. you then tie up your hair if you have any, start the headset and it connects over bluetooth. i have got a big head so it goes on and it fits me really nicely, actually. a week current stimulates the part of the brain that is usually less a even those with depression. it isa even those with depression. it is a weaker version of similar treatments already delivered by doctor in tenex. it 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. close your eyes and direct your focus into your body. focus on your breathing. i did 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. try not to think about these thoughts is distracting. they are actually part of mindfulness practice. miscommunication 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 and it knows i have done 63 of the chat sessions andi done 63 of the chat sessions and i can see on this treatment programme that there is a downward curve and a downward curve m ea ns downward curve and a downward curve means i am feeling less depressed, which is really important, obviously. when you are on your medication, you don't know how you are doing but with this treatment, you do. things have changed, fairly fundamental, things like being able to engage with my children more, being able to do things that i find relaxing. being out of the 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 from around the world. i think this isa around the world. i think this is a potential first—line treatment for depression. particularly for people who

cannot take antidepressant medication or might not want to ta ke medication or might not want to take antidepressant medication, or who don't want to psychotherapy. that doesn't mean that the treatment comes without risk though. considering that people might use this instead of getting or having a proper assessment and getting proper help. how long you can use it for, how much and how often you can use it, long—term effects — all that needs to be looked at more. theirfounders in needs to be looked at more. their founders in sweden except the device won't work for everyone. it is the same for all treatments, even as a clinical psychologist, i know that up to 60% go out of the clinician's office and have a flow on effect from cbt for example. we know that is true for antidepressants also. flow is now running a clinical study to see the efficacy of combining the up with the headset. but they believe it is

the up that will really keep users on course. many people say look at the headset and think that this is the new thing but the app is at least as important. the jackpot has many, as important. the jackpot has any as important. the jackpot has many, many functions. we want to be able to explain to the user that it is important that you follow the treatment protocol, we want to be able to remind them of 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 — 18 —year—olds to improve mental health with its floating ai driven jackpot. let's get started and remember —— chatbot, i am started and remember —— chatbot, iam here started and remember —— chatbot, i am here with you every step of the way. this one uses cognitive behavioural therapy to help those

struggling with negative thoughts. while these choose your own adventure games help in still useful emotional fitness skills. apps like these have become increasingly popular in the wake of the coronavirus pandemic. but although they may help, it is 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 as ——at home, as well as movies and tvs, many of us have been gaming monomer used to. in fa ct, gaming monomer used to. in fact, the click team are having a weekly acro to competition every friday and lara is wiping the floor with us most weeks. as well as being attraction from everything, there is one game and has actually been recruiting its community to help research covid—19.

eve online is one of the biggest online multiplayer role—playing games out there we re role—playing games out there were 300,000 monthly players. set in space, you can be anyone, a fighter, a trader, even a pilot. while exploring the universe, players can also engage in a mini game called project discovery where they analysed cell clusters. although it is just part of the game for them they are actually sifting through real world data for researchers who are examining how the coronavirus affects odd cells. it is a gamified version of a scientific technique called flow cytometry which is measured to measure characteristics of the operation of cells or particles. so far, over171,000 players have completed a7 million tasks which amounts to 36 years of categorising cells. you look at a plant and you

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, you know someone who has it and just the fact that i can sit here at my desk while waiting for a fleet, doing something that is going to contribute to helping find out information about covid—19. contribute to helping find out information about covid-19. the data generated by the players accelerates the scientist's ability to determine what is 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 have been given even more complex tasks by the team behind the project.

it is really just like by the team behind the project. it is reallyjust like citizen science to a tee. you have a giant group of people and we made this fine, gamified are quite a bit. there are incentives for people to do it to boost their game experience but it is also just the heart and soul of our community as well. these are things that people really enjoy and this is really 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. what we are going to do guys is set 10k ofa are going to do guys is set 10k of a target, really quick and then walked to the run spot. does that make sense? yes. outstanding. standby. and it is not just about the bonuses for the players. eve online's community is keen to support the scientific effort in the fight against covid—19. the scientific effort in the fight against covid-19. that it is phenomenal that i have this opportunityjust playing is phenomenal that i have this opportunity just playing a videogame. and i think that is

really what got me into it. i considered my desk in the comfort of my home and i can help researchers do something. you know, make a difference. that is kind of cool. how brilliant is that? now, we're going to continue with our health theme and talk about surgery, our health theme and talk about surgery, specifically keyhole surgery. surgery, specifically keyhole surgery. this is something that can be quicker than normal surgery, because can be quicker than normal surgery, because less trauma and it can reduce recovery times. this kind of surgery can be carried out by remote—controlled robots. it is just not that widely available. but paul carter has been to see a new type of robot surgeon that could change that.|j a new type of robot surgeon that could change that. i am certainly no stranger to scrubs. you can see the arms moving behind me. they almost look like they are moving independently. this us robot still dominates the market but

it is big, heavy and cost nearly $2 million a pop. but now there is a new british pot on the block and this helps to aim patients kill quicker by just a few access cuts. it turns out, stacking tiny box is perfect for surgeons in training. today, only around a third of people who could have keyhole surgery actually get it. it is hoped this small mobile set up will make it more accessible. what of the differences with this design is thatis differences with this design is that is modular which makes a portable. which means it very, even someone portable. which means it very, even someone like me should be able to move it. surgeons where three day classes 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 field. when you're not doing the surgery, the theatre often stands empty.

you could fold this up and move it to the theatre next door to a colleague number to make who wa nts to a colleague number to make who wants to use it, honestly, in a few minutes. there is no tremor because the instruments take that away from it. anything you can give that reduces the physical strip, it is a win. what is amazing is the level of movement. it is like you're playing a nintendo switch. it looks like a game but is not a game, this is, you know, life and death, quite literally. game, this is, you know, life and death, quite literallylj and death, quite literally.” can get it exactly where i wa nted can get it exactly where i wanted and it's really relatively effortless. he has completed more than once thousand operations this year, rolling into several nhs hospitals, including this one in surrey. it is proving particularly useful amidst the coronavirus pandemic. this operating theatre, we are only using because of covid. we wouldn't be able to get the other robot we use into this because it is just too tight.

all of these models you can see a quite small. we can move them during the operations and you are only constrained by the number of units you can get around the table. but the robotic carts aren't just around the table. but the robotic carts aren'tjust moved around the wonder room. ultimately, long—term, it will also enable us to use the same robot between theatre so you can get much more use out of a single machine. in the future, devices could even be shared between completely different hospitals. because the units are so hospitals. because the units are so small, they can be packed up, we could put them on a truck and bring robotic surgery a truck and bring robotic surgery closer to patients rather than have than necessarily travel so far just to one sent a. that is notjust convenient but 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 also 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 have enjoyed it was right anyway,

thatisit enjoyed it was right 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 abc click. thank you for watching and we will see you soon. you for watching and we will see you soon. goodbye. hello there. after a couple of cold and frosty mornings with a bit of mist and fog around, we'll start to see some changes to the weather this weekend. that's because lower pressure will be moving in, bringing milder weather to all areas by the end of the weekend, but also outbreaks of rain mostly across southern and western areas. our big area of high pressure which brought the settled weather will be dominating the scene this weekend across the near continent. this area of low pressure

will start to push up into southern and western areas, and the breeze will be increasing as well. already a breezy start across the far south west. elsewhere, it's a chilly start to saturday with some mist and fog through central scotland, north east england, eastern wales and the midlands. the best of the sunshine will be across northern and western areas, and some sunshine also pushing into southern counties of england by the end of the day. we'll also see some rain arriving across cornwall and devon, too, the first of a series of weather fronts. here, it will be windy. elsewhere, the winds light, but certainly stronger than they have been of late. so it will be a milder day across southern areas, 1a—16 degrees. another chilly one further north. now, through saturday night, looks like it'll be chilly and dry to start with across northern areas, where that band of rain spreads its way northwards. and by the end of the night, it'll be lying across northern ireland, wales, the midlands and into the south east. here, it will be milder because of the rain. fairly chilly in the north for a while, but those temperatures will start to rise as we move into sunday morning. that band of rain moves northwards across the country on sunday, and this next one will arrive later

on sunday into monday. so, it'll be much a cloudier day across the country. that band of rain across central and northern areas will push into scotland, turning lighter and patch year. behind it, we could start to see some sunshine developing across northern ireland, wales and the south west. but here, it will be breezier, and in fact further north the winds will be a little stronger than they have been of late. the milder air reaching as far north as northern ireland, so northern ireland up to northern england, southwards 1a—16 degrees, 10—11 degrees across scotland. but the mild air reaches scotland as we move into monday. we'll see more weather fronts pushing into mainly southern and western areas to bring outbreaks of rain. some of it could be on the heavy side. but the theme as we move through the week is for higher pressure to keep eastern areas generally drier. the further west that you are, likely to see the influence of that area of low pressure, which will bring further spells of rain at times.

joe biden is expected to address the american people

this is bbc news. i'm lewis vaughan jones. our top stories: joe biden is expected to address the american people soon after pushing ahead of donald trump in two crucial states. mr biden is increasing his margin over the president in arizona. but a recount is announced in georgia, wherejoe biden's lead over donald trump isjust a,000 votes. this is going to be a razor—thin margin and a recount will likely be in order and i do think it's appropriate, just to ensure the integrity of the election, but i am very confident that these results will stand. joe biden has built up a lead of nearly 20,000 votes over donald trump in the crucial vote count in pennsylvania. the city's mayor says trump must admit defeat.
