this is bbc news. the headlines: the world health organization raises its assessment of the coronavirus threat to the highest level as more than 50 countries report infections. but the head of the organisation says there is still a chance to contain the virus if its chain of transmission can be broken. fears that the outbreak could hit the global economy led to a sixth day of sell offs in stocks and shares. in the us and london, markets suffered their biggest weekly loss since the financial crisis in 2008. companies around the world have lost more than $3.5 trillion in value. there've been violent scenes outside france's most prestigious film awards, the cesars, after roman polanski won best director for his film for his film an officer and a spy. more than 100 women's rights activists protested at the award nomination, clashing with police near the venue. after he was announced as the winner, several actresses left the ceremony in protest.

three former barclays executives have been acquitted of charges of fraud in the only criminal trial of senior bankers in the uk over events in the 2008 crisis. our correspondent andy verity has been following the case and has this report. former senior barclays executive, rogerjenkins, once described as the best paid banker in the city, along with former senior banker tom kalaris and a lower ranking executive, richard boath, were accused by the serious fraud office of committing a fraud in the midsts of the 2008 crisis. charges they have spent a year on trial denying. in may 2008, barclays, like other banks, was running dangerously low on cash. regulators were pressing the bank to beef up its finances and put billions more aside in case some of the loans it had made weren't repaid. directors set in motion a plan to raise funds privately from sovereign wealth

funds around the world. with tom kalaris co—ordinating it, one of then chief executive bob diamond's trusted lieutenants, rogerjenkins, the head of ba rclays capital in the middle east, seen here on the left, had got to know sheik khalifa bin hamad al thani, the prime minister of qatar, and convinced him to invest £2.3 billion in barclays, along with sovereign wealth funds from china, japan and singapore. each investor would get a fee of 1.5%, but then the qataris demanded more than double that. between you and i, we had a meeting today with the man from q. yes. so he's now angling for a 3.75% fee. laughter. amongst other things. out of £3.50? yeah, mate. well, they have got us by the balls, because the price is so low, that's the problem, mate. the court heard confidential phone calls where richard boath kept raising concerns all investors were supposed to be paid the same, but the message came back

from the top the bank wouldn't pay more to everyone. if we are receptive to that fee number, are we going to apply that across the whole transaction? no. i will deal with it. just put it on the side. the qataris would be paid their extra fees, £a2 million, via an agreement for advisory services. then, when the crisis worsened in october, barclays needed billions more. the qataris again demanded extra and barclays added a further £280 million. here at the old bailey, the prosecutor's case was that those advisory agreements were pretend — an attempt to disguise the extra fees being paid to the qataris and that the defendants caused the bank to lie in public documents, saying no extra fees had been paid. the defendants pointed to evidence that what they'd done was approved at the top of the bank and that the board of directors knew about it. the court heard that the bank's lawyers, including the big city firm, clifford chance, advised that it was legal, as long as the qataris would be giving valuable services in exchange for their extra money.

today, the only criminal prosecution of a senior banker since the crisis finally drew to an end. andy verity, bbc news, at the old bailey. now on bbc news — click. this week, how can this fit in here? and is the new folding while way up to scratch? and it's my entry for eurovision —— huawei. heart rate, temperature, steps, diet, these days we can track all of

oui’ diet, these days we can track all of our vitals. all of this data can help us to understand and tweak our lifestyles, but it's also moved way beyond the basics, allowing smart phone connected devices to monitor conditions like asthma or diabetes from home. lara lewington has been to meet someone was using something a little bit more advanced a smartwatch to monitor his health. he's had a tiny computer inserted into his heart. around 26 million people worldwide are suffering from heart failure, where the heart is struggling to pump lard around the body. for some time now technology has been used to keep track of heart conditions. so i've come here to hammersmith hospital, where an innovative procedure is being carried out. 71—year—old retiree andrew lives with heart failure, requiring

precise medication to keep him well. what's stopping it is breathlessness isa pain what's stopping it is breathlessness is a pain in the chest? well, it's breathlessness. but it's not like a fit person's breathlessness. why was having a monthly appointment with consultants, of course, with walking is always a problem, because there was a quite a long way apart and you can walk 15 yards and then i have to pause and gather breath —— but then they have to. today, though, andrew's havering a tiny microcomputer inserted into his heart. what we want to offer you is a device that will sitjust on here thatis a device that will sitjust on here that is able to monitor the pressure in the left atrium. it will give doctors access to continuous data so any changes to his condition could trigger an alert. getting prior warning would keep me out of hospital and would mean a could be treated at home. this is the second procedure of its kind in the uk. up

until now we've never been able to get this data in a patient who's not in an operating theatre with a catheter positioned in the heart. so this is, potentially, a major step forward , this is, potentially, a major step forward, it means we can adjust the medication in the early stage, which reduces symptoms and, critically, reduces symptoms and, critically, reduces admissions to hospital. the device is threaded through the veins into the heart. once in place, it swings will open, securing a sensor inside the left atrium. in the really cutting—edge bit, a microcomputer in the right. to reduce the size of the implant, we developed a proprietary technology that enabled digital transmission of the data without a battery. that enabled digital transmission of the data without a batterym charges a bit like a phone with a wi reless charges a bit like a phone with a wireless charger. the bill powers

the device as well as sucking the data from it so it can be sent to the cloud. from there, ai algorithms interpret the readings to flag if a doctor needs to take action. the more data we will gather throughout the time, the better our ai based system will be. finally, it's time for andrew to go into surgery. doctors use ultrasound probes and x—ray vision to see inside his body. equipment is fed through his veins and a central wall in andrew's heart is pierced so the device can be put in place. this is usually the riskiest part of the procedure. the device is now going into the heart. fortu nately for

device is now going into the heart. fortunately for andrew, all goes to plan. as this is the only way to get data directly from the left atrium. the device has now been released from the catheter and is sitting on the septum. you can see the two sides of the umbrella of the device securing it. the procedure has gone very nicely. it's a perfect result. a month after the operation, we met to look at the data that had been collected and how useful it seemed. these look like perfect phrases, like the traces we would see if we had an invasive catheter at the time ofa had an invasive catheter at the time of a procedure. so this is very, very good quality data. what does this mean for the data you're looking at long—term mozela we will be able to see changes within the pressure in andrew's heart. and this is likely to be before he developed symptoms, so we can adjust his medication to try to prevent worsening of his symptoms. in that

way we will be able to keep andrew as he is now, nice and stable. how has this changed your life? emotionally it has. in that eye can see a future now. i've felt i'd just been put in a filing cabinet, just waiting for something nasty to happen. but now there's possibilities of further treatment. what would you say to anybody else ina similar what would you say to anybody else in a similar situation to you about the trailer what you've experienced so the trailer what you've experienced so far? consider it. ithink it the trailer what you've experienced so far? consider it. i think it will improve their life. hello and welcome to the week in tech. it was the weak concerns over coronavirus wiped more than $238 billion of the stock value from the five biggest us tech firms. the uk broadcasting regulator of found that radiation levels of 5g are well within health and safety limits and the us enquiry found that the death ofa the us enquiry found that the death of a tesla driver, while his car was in self—driving mode, was caused by the driver's overreliance on the

autopilot system. in is that really necessary robot news, how about searching for a book with an autonomous librarian? it is a service but that guides you to books you are looking for. and if you're suffering from carrying just a few too many, will carry them for you. if you've ever thought a robot could do with a soft touch, a jellyfish would probably agree. this silicon fingered robot helps pick up jellyfish and other deep sea creatures without accidentally squishing or harming them. the handy soft but also seems to cause less stress to the animals. and, finally, researchers at japan's osaka university have developed a robot that can feel, sense, and express pain. but, for someone think of all reason, then made it look like a child. the disembodied robot is programmed to smile, grimace, and wince, it is hoped that teaching it to recognise pain will help the artificial intelligence loan empathy and so better care for humans. let's

just hope it doesn't learn to feel revenge. the end of february every year is a big time for us. having painstakingly played for months and fought thousands of other journalists for access to the big stories, we had to barcelona for the mobile world congress. it's where the big companies launch their big new phones and the small companies show of clever new innovations that may one day change the world. only this year, as you may know, it is off. cancelled because of concerns over the spread of the coronavirus. it's proved a nightmare for the telecoms industry but chris fox, who was due to cover, thinks he's going to get a week off, however, not eve ryo ne to get a week off, however, not everyone has cancelled. some companies have gone to barcelona anyway. so i've got a bit of news for chris. the cancellation of mwc

has been nothing short of a nightmare, especially for me, couldn't cancel my flies at such short notice and i'd been left stranded here in barcelona with no work to do. —— i have been. it turns out huawei hasn't cancelled its flies either and are still doing a press c0 nfe re nce . flies either and are still doing a press conference. right now. with the venue already booked and huawei executive richard you already in town, the company decided to do is launch event anyway. only this time it was pre—recorded a day early and played out on the big screen. the big reveal was the follow—up to its first folding phone. and here it is. the folding huawei mate access. if they open the incident with pictures of dogs, and if i open it the pictures expand to fill the view.

what a country was google maps, because the phone still doesn't have those google apps. huawei has now added its own at gallery which it says will be a competitor to the google play app store. snapchats, tick—tock, they are on there, this i newspapers on there, and bbc news, but some big ones are missing, of course. the concerns with folding phones as the displays might be easily damaged because they are flexible. huawei says the original meat eggs it has made the liz screen more resistant. they have seen a display screen with a big old great honour. huawei says there will be cases available. also revealed was a smart speaker, it is called the soundex. all you do is tap the phone to pairand then soundex. all you do is tap the phone to pair and then you can play your music, including from spotify, because that is in the upper gallery. so here we go. music plays. quite loud. so one thing they did tell me was you can put your hand over to

silence the speaker if it's too loud. and that should have silenced it then. the companies is the way the speakers here are configured as one faces this way and one faces the other way so the vibrations cancel each other out. so they say you can turnit each other out. so they say you can turn it up twice as loud as the apple home pod without it vibrating itself off the table. and that and can we talk about product names? we have the made book, the mate pro, the mate pencil and i wonder where they have got their inspiration from? on the outskirts of town, toothbrush giants oral b pressed on with a light show and dinner and if you are why enduring why they are here at the conference, well, the toothbrush has bluetooth in them... obviously! the new oral b has a magnetic drive they say is whisper quiet, although detest that i have to go somewhere silent and knowjust the place! usually at this time of

year this place is full of the world ‘s mobile phone industry and i cannot think of a quieter place to test the toothbrush and here we go, i will hold at the same distance as my microphone and this is the regular oral b. very noisy. this is the new one... also, fairly noisy and they said in the presentation this is the toothbrush that whispers but i am not convinced that is a whisper. the ultimate test is whether you can hear it through the bathroom door and whether it will disturb your partner so we tested that in the hotel and the results are, yes, you can still hear it through the bathroom door. and the new view 30 pro phone has a dual view of recording mode c can take photos with a longer and close—up

lens at the same time. real me was planning to come to the conference for the first time but they did it in madrid instead. it comes with a new focus mode that let's you lock yourself out of the phone for a few minutes and listen to relaxing sound. perfect to combat the stress of reorganising your plans because of reorganising your plans because of coronavirus. and event has risen from ashes of this years wmc. the phoenix event was planned for companies to meet and pitch their ideas. i don't think anything or substitute person—to—person interaction. i had this conversation with someone this morning and when you have a physical connection, we think business is different. in the end, the wmc was not a complete disaster for everybody. some interesting 5g animation going on underground just in time for wmc week as we found out. recently, it

has been impossible to avoid 5g at wm but this week you can because there is no show — — mwc. these halls are in really silent but one project looking to make its debut for the event this year has still gone ahead and it is all happening below the surface. and before shoko was even reach mwc they were going to experience a superfast mobile network coverage on the underground on the way there. the 5g barcelona initiative was set up to provide the city with the next generation of mobile broadband. it is currently available between four stations of barcelona pass train service,

including europa theatre, the closest station to where mwc takes place. —— barcelona ‘s. but it's not just available on the train platform, 5g is available in the tunnel as the train travels, becoming one of the first in the world to do so. let's see how fast the coverage is down here. i was getting around 1.1 gigabytes per second on average on the platform but it was quite a bit lower when travelling on the train. the speed does differ between going down the tunnel and being at the station. slightly is lower in the tunnel and it does vary. sometimes it can be as high as 500 make or as low as 170 but saying that, you are still getting decent coverage in a tunnel! and it means we can watch a bit of click with barely any loading time whatsoever. and how is this achieved? well, whatsoever. and how is this achieved ? well, we whatsoever. and how is this achieved? well, we waited until the train service was closed so we could get into the tunnel and check out the sg get into the tunnel and check out

the 5g antenna. each set of antenna night are roughly 500 metres apart with 15 install between four stations but only vodafone provides sg stations but only vodafone provides 5g coverage in barcelona and they own all the masts on the train line but the plan is to do it for the entire train network. however, there is no clear date when this will happen. 5g requires more masts than previous network connections so this setup can be quite complex. these are the first steps. very difficult for us to make all the installation at this moment. it is expensive. but we think it is a good investment for the city. if other networks come in and say they want to do 5g down in the rail network, will vodafone share the masts or will they have to install their own? we will provide our own and perhaps it is possible,

of course because vodafone is the owner of this network. you have to hope they say yes? we have to be prepared for this situation. but, until then, this 5g set up will act asa until then, this 5g set up will act as a test for companies to create their apathy to improve our way logistics and what they can do on their phones and during the journey —— apps. it looks like 5g will be pa rt —— apps. it looks like 5g will be part of the daily commute on their travels but when we were testing the sg travels but when we were testing the 5g network, we hit the data limit, we hit ten gigs so you want to switch to an unlimited plan! this is a piano and this quite frankly is all i know how to do. play these four chords over and over again until you get a massive hit, trust

me, it works. learning an instrument properly takes hard work, skill and a great teacher, none of which i have, but take a look at this. this is ar piano. point your phone at the piano and you get a virtual virtuoso to show you how to tackle complex piano pieces and you can so it right down getting really close to see how you are supposed to shape your hands as he moved from one note to the next. the problem is i'm not sure how to hold the phone with one hand and get both hands in to copy what he is doing, so... there is a way to get more hands on though or more accurately, hands in. we have tried accurately, hands in. we have tried a prototype which its makers promise

can teach anyone to play. this little keyboard wants to teach you how to read music. so many people come up to me and say i really wish i had learned to play an instrument but it's too late for me now and i really don't think that's the case. certainly with some technology, it could be easier than you think to play your favourite song. music company took me inside their hq to show me their proto— cart type keyboard, a light up bluetooth device aiming to give everyone an opportunity to learn their favourite song. now, light up keys are available on quite a few entry—level keyboards but the lumi has multicoloured leds to make it easy to find where you are if all the notes are the same. sheep mesic has sedate the same hundreds of years,

originating from writing down movements the choir. the ceo of roly feels it is time to bring music into the 21st century. still most people when they learn to play music, they need to read music with a traditional score. that is a call based technology. even the shape of the notes, even though they are not perfect circles, has to do with a quill pen and how you would write without and that kind of calligraphy from 500 years ago. it is remarkable that that form of notation and syste m that that form of notation and system is still what we use today. the device connects to an ipad and with the help of an app and something that gives you a little bit more than just notes of a page. there is an element of intimacy or even privacy with the music learning experience. if you have a lumi and the lumi app and put on your headphones, you are in your own

learning word and go at your own pace and the app will give you feedback. it is between you and the instrument and you do not feel like necessarily you are being judged in a way that you may if you had a teacher or parents looking over your shoulder. it is likely the software may prove more lucrative than the hardware. she is a song from a list of licensed partners and the app encourages people to learn to read that music. first, blocks that wait for you, a bit like guitar hero. then, you have to play in time where the colours help you find the notes and finally, full—blown, grown—up score reading. once you become a skilled musician, you get to a point we close your eyes and have the relationship between the sound and your muscle memory and your body. and there is a point at which you can let the visual go as part of a primary form of musicmaking, you

know, and even music learning experience. but to get to that point is very difficult for most people — and most people fail because they feel, i think, and most people fail because they feel, ithink, that and most people fail because they feel, i think, that the overall syste m feel, i think, that the overall system is too complex and too austere. i found the device visually pleasing and felt the urge to customise colours, a feature may seem customise colours, a feature may seem to become available. accepting latency issues, it is a clever but slightly pricey theory to learn theory. those with extra cash can put a few together and get a longer keyboard. regardless, iwill take the opportunity to encourage anyone to see this ticket on a piano, keyboard or any instrument because when it comes to learning, it's never late to start. and that was it for this week. do not forget we live on social media so you can follow us throughout the week on facebook, youtube and instagram and twitter at

bbc click. thank you for watching and see you soon. hello. friday brought more rain to areas which didn't need it. another 10—15mm fell across shropshire. around 40mm of rain fell in around 12 hours in cardiff. meanwhile, across scotland, further snow. through the weekend, parts of the highlands could see another 20—30cm of snow, and all eyes this weekend are on this area of low pressure. this is storm jorge, which was named by the spanish met service. through the early hours of saturday morning we will see squally rain pushing east. cold air coming in behind, we could see icy conditions across parts of northern ireland first thing on saturday. but the main focus this weekend

is the strength of the wind. gales, if not severe gales, across a large swathe of the uk, gradually easing down through sunday. wet and windy first thing across the eastern side of england. sunshine following. showers pushing in from the west, likely to be wintry. wet and windy across the northern isles through the afternoon. more persistent rain and maybe hill snow across northern england and into southern scotland. a cold day, particularly when you factor in the strength of the wind. temperatures not much higher than 6—7 celsius in places, and some gusty winds, quite widely 40—50 miles an hour, but through the afternoon, some really strong winds developing across parts of wales, northern england and into southern scotland, where they could gust up to 75 miles an hour, maybe even 80 miles an hour on the western coast of scotland. also some heavy persistent rain for a time across northern england, southern scotland, northern ireland and also some snow once again over higher ground. through the early hours of sunday morning we keep this focus of rain and hill snow across northern england and southern scotland.

to the north and south of this, clear spells, but squally, blustery showers. the strength of the wind should keep the frost at bay first thing on sunday morning. storm jorge slowly pulls away north through sunday. we're keeping an eye on this feature here, which will start to push outbreaks of rain into south—east england through sunday morning. two things to keep an eye on. the winds will be slowly easing down, but still some outbreaks of rain and snow across northern england and southern scotland. rain for a time perhaps across south—eastern england. we will need to keep an eye on the timings of that. between all of this, spells of sunshine, wintry showers, the wind slowly easing down, but it's still a windy day. certainly still feeling cold given the strength of the wind. we start to lose those severe gales as we go through sunday. it's a blustery day and for most there'll be a mixture of sunshine and showers. that's the theme into next week. it won't be as windy. it will be somewhat drierfor a time. still, some showers around. goodbye.
