this is bbc news. lam ben i am ben bland. the headlines: violent clashes between protesters and riot police have continued into the night in the spanish city of barcelona. earlier on friday, about 500,000 people held a peaceful demonstration against the jailing this week of catalan separatist leaders. british mps will be heading to parliament in a few hours in what's been called ‘super saturday‘ — a special vote on prime ministerjohnson‘s new brexit deal. he spent friday trying to secure the 320 votes the government needs to win a majority for his agreement. 0ne president trump's most loyal supporters, the senate majority leader, mitch mcconnell, has condemned his decision to withdraw troops from syria as a "grave mistake". writing in the washington post, he said it would embolden washington's enemies and leave

americans less safe. now on bbc news: click. this week, portable ultrasound scanners, this week, portable ultrasound scanners, brain music, and robot dogs that clean up after themselves. theme music. 0ver over the years on click we have seen devices get smaller and smaller. yet, with more storage and more processing capabilities. this

miniaturisation of devices has touched everything from our computers to phones and even revolutionising areas of medicine. 0ne revolutionising areas of medicine. one area of medicine which has a lot of demand and could potentially benefit from miniature as a sin is medical imaging. in the uk, over 41 million scans take place every year in the nhs using x—rays, mri and ultrasound. in an emergency, at the bedside or even at an ambulance, it can become placated to get a patient to one of these large machines. does my complicated. but now portable medical devices made in the uk could change 0liver, giving doctors and patients instant access to ultrasound at a reduced cost. the intensive care unit of southampton children's hospital admits hundreds

of patients it's year. with a range of patients it's year. with a range of medical conditions, from heart disease to trauma and neurological emergencies. effie was admitted with a lung infection and needs constant monitoring with tests, x—rays and ultrasounds. usually these are performed by expert radiologists and they aren't always immediately available. this ward has four point—of—care ultrasound available. this ward has four point—of—ca re ultrasound machines. these two cost over £50,000 each. but now the same test can be carried out using a smart phone up and probe, which fit into a doctor's pocket and cost a fraction of the price. she had heart surgery yesterday for a condition which is a problem in the heart where there are four different issues. one of the complications of that is sometimes fluid around the lungs. so it southampton we have a routine scan of children's tests to make sure all the fluid is gone. this ultrasound system is called the butterfly, and

consists of a hand—held probe which its arches to and i were a smart phone or tablet. this is now filming the long and the diaphragm. that long looks completely normal. there is no fluid around the lung, there is no fluid around the lung, there is no fluid in the lung, the lung is moving well. it costs £1699. a fraction of the cost of the larger machines. and it's less invasive at a child's bedside. it's usually designed without all this in mind, what with ashley got here is a whole variety of paediatric settings as well. so i can select paediatric long, paediatric heart, paediatric afternoon, but i could also flip and standard adult long, it nowjump between one probe with the president button rather than changing the probes over and over to get the right probe. let's put on the jelly... well done.

he is so electric crystals are used, crystals are cut into different shapes and sizes as different frequencies are used to image different parts of the body. but this also means different probes are needed. the butterfly uses ultrasound on a computer chip and needs only one probe for different body parts. we are well's first ultrasound on chip, a single probe whole—body imaging system, instead of the typical 124 imaging elements that are in a ptc probe, there are almost 9000 elements in this. so we can recreate all the different types of probes with just one. that becomes really important as you scan different parts of the body in an emergency, you don't have to keep shifting probes. just a simple change within the application itself you can go from heart and lungs very quickly and make rapid decisions on what is ashley wrong with the patient. the information from the app can be anonymous smoothly sent to a secure server for doctors to review quickly —— anonymously sent.

the implications are clear. an estimated 5 billion people around the world don't have access to medical imaging of any kind. in sub—saharan africa, the devices being used to check for pneumonia, the leading infectious cause of death in children under five. in fact, the company's chief medical officer made his own alarming discovery when scanning himself during the device's testing. we were doing these studies are fda clea ra nce, we were doing these studies are fda clearance, i noticed some softness in my now, i put the probe in my note and i shockingly saw a very large mass which ultimately turned out to be a cancer. i am living proof that having an immediate access to an image contains your health and your life! southampton has bought four of the devices and plans you always have one available in its children's ambulance stop when you are in front of a child

thatis when you are in front of a child that is critically i'm well and you desperately need information, you are relying on a third person and you are watching a child deteriorate and you feel powerless. actually, this gives you the power. this gives you the information to look inside to keep as ‘s chest. it gives information to look at the heart. you can decide yourself within seconds. and suddenly, looking after sick children is a bit less scary. for now, the butterfly is only available to medical professionals. but tests are currently under way with a group of cardiac patients scanning themselves at home. the artificial intelligence built into the device will help guide the presence of the right area to scan, and perhaps with regulatoree approval, at home ultrasounds could bea approval, at home ultrasounds could be a reality. tate modern in london opens a major show of the work of the korean visionary nam june paik

which brings over together 200 of his pieces. his one who made a career of being ahead of his time. he was the ultimate early adopter. he was the ultimate early adopter. he came up with the idea of wearable tack, he codeveloped the first video synthesiser in 1970. he coined the term electronic superhighway in 1976. and, he vj'ed a video cast in 1974. let's take a look later at this strange experience. although paik was korean, a lot of his work is influenced by japanese paik was korean, a lot of his work is influenced byjapanese culture and he spent a lot of time injapan. no—one loves a robot more than the japanese, and i right? injapan is where we are heading now for its annual extravaganza. —— annual tax extravaganza. ——

technology. some things that japan's annual extravaganza. —— technology. some things thatjapan‘s annual paik shindig can leave people speeches, but unfortunately, not for emily. now, over to the kitchen, is your robot dog trying to tell you something? sony's aibo is now faithful to hitachi's appliances. if you leave the fridge door open or the washing machine on cycle, he will come over and bark because an alarm wouldn't sound is cute. he even rides the robot cleaner, just like real dogs. and with these transparent tv screens from mike sharp, shop windows may never be the same again. —— from

sharp. this is something i'm presently quite interested in and excited about. i think it's something many of us had been waiting for four years. how do we know whether we've got a cold or we've got a virus or maybe it is a bacterial infection? 0ften our doctors take best guesses but they don't really know. part of the reason for that is any sample they take, if they do, takes a few hours oi’ take, if they do, takes a few hours or maybe even a couple of days to tell us what we've got. murata at 0saka tell us what we've got. murata at 0sa ka university have tell us what we've got. murata at osaka university have created a portable device that gathers bacteria, making it quicker and easier to analyse. a laser is pointed underneath the sample that is on pointed underneath the sample that isona pointed underneath the sample that is on a substrate, basically a plate thatis is on a substrate, basically a plate that is based on this device, and we can see here what the microscope is seeing. now, look closely and you will see the movement of the water that surrounds the sample. the sample can be food

if we want to detect something that could cause food poisoning, or something detect something that could cause food poisoning, orsomething in blood or in urine or spittle or any sort of substance that we might analyse from the human body. the movement of water is causing a concentration of the bacteria, or indeed the virus, down towards the bottom towards that plate. so there's no need to grow anything. there's no need to look too closely because everything is concentrated ina because everything is concentrated in a small because everything is concentrated ina smallarea. because everything is concentrated in a small area. this is about the size of a mobile phone. the idea is that could be deployed into field clinics, into ourgp that could be deployed into field clinics, into our gp surgeries, and the results of that, they are saying, would come back within minutes — not ours, not days, but within a few minutes. it's still early stages, so don't expect anything for two years or so. it is easy to see the impact it could make. sony devoted its entire stand

to self—help take this year. including this cell analyser that tracks biomarkers which can help detect cancer and uses lasers that may be familiar to you —— devoted to health tech. this is similar to a blu—ray player. it uses scattered light to detect what is going on in the cells. damn, what on earth is going on over here? just trying a little bit of surgery. surgery? are you a brain surgeon now? with these sd you a brain surgeon now? with these 3d glasses and a 3d screen there, this is one of the best resolutions for any surgery. this is actually used, this camera here is actually used, this camera here is actually used in surgeries. and the check is not to look down at what you are doing inside his brain, for example, it is to keep looking up at the screen and still you've got the peas

that you want. very good! and then, look at how small that is! that is absolutely tiny. look at this. that is so small. i'm no brain surgeon, emily, i can tell you. i'm busted. this is child's play. and finally, dan found a visible way to conversed with the locals here they didn't involve flapping his arms around. konichiwa, hajimemashite. i have no idea what that means, but with a swipe of the finger, here is the english. "hello, nice to meet you." it was the week that a robot develop a rubik's cube single—handedly. it took about four minutes to complete the challenge.

u—tube and other things —— mtv. he also understood that personal communications were important in bringing people together beyond any national or cultural boundaries. "electronics superhighway" is one of the terms he coined as early as 1974, and he thought that connecting different cultures and different people in different countries could actually help people understand and avoid conflict. although nam june paik is well known as being a pioneer of video art, he is also a pioneer of interactive art. this from the 1960s is three camera participation, whether there viewer of the work necessarily becomes part of it. way backin necessarily becomes part of it. way back in 1963, nam june necessarily becomes part of it. way back in 1963, namjune paik made a work called "random access", which showed that a linear medium like audio recordings could be non—linear. it consisted of strips of audiotape and a portable cassette layer with an extended magnetic tape

had that could be dragged over the strips in any direction. he employed tvs as an artistic medium for the first time. tvs were very expensive electronic machines than, and only a few families could actually afford tvs in their household. paik was certainly way ahead of his time, so i wonder what he would have made of what emily and dan have found in japan? what could possibly go wrong? this isa what could possibly go wrong? this is a single seater, sort of, flying ship. you have got to want to make this happen, people! this is brilliant! that was amazing! the tea m ta kes brilliant! that was amazing! the team takes part in a global

competition, for real, in the us in february. in summer we saw nec lift off its flying taxi. part of the excitement of that initial launch, it feels like things are slowing down here. and that is because things like the infrastructure to actually get these off the ground in cities is simply not in place at the moment. any is eight hour working with the japanese government to hopefully get an crude version of these off the ground and entities by 2023, which would be pretty impressive. -- in cities. last week we spoke about electric cars and he was an idea to recycle the batteries. 0ne nissen leaf can enough —— ‘s dornauf solar energy to power 12 of these streetlights. 200 a plan for next year. you can also charge your phone from them which is useful in disaster situations, like the one japan had last weekend with

the one japan had last weekend with the typhoon. now take a look at these, underneath my feet. they are solar panels, and they are charging that electric car. it seems like a bit of a no—brainer, these can hold up bit of a no—brainer, these can hold up to 20 tons, very useful, and i think the company producing them believe that by 2022, we could have roads made of these, so you can be charging up while you are driving. murata showed off a clever holographic style image that you can actually feel. 0h! (laughs). that is really weird. i wouldn't normally/ jellyfish. dozens of piezo electric actuators and auto blowers direct airto actuators and auto blowers direct air to where the image is meant to be. over at mitsubishi electric you had holographic signing tojump through, but how about this, a projection that replaces the vending

machine or atm? it is more hygienic and all they need to do now is make the money appear out of thin air. meanwhile, i am writing a dustbin lead. itjust meanwhile, i am writing a dustbin lead. it just doesn't meanwhile, i am writing a dustbin lead. itjust doesn't like going forward ! lead. itjust doesn't like going forward! tdk's six axis since a gaming disc could be the future, but iam not gaming disc could be the future, but i am not so sure. i am really not very good at this. emily and dan in japan. now when we are feeling joyous, sad, angry, we try and find music to fit the mood. not sure that is it right now if i am honest, but what if you could guarantee to find the right song for the moment? well thatis the right song for the moment? well that is what lj reg has been looking at. here is a personalised station of party songs. voice actualisation technology is good enough to capture imagination, and with smart speakers

letting us here virtually any song on command, it has made music more consumable than ever before. today, sonos are showing off their products with some unexpected technology art installations, totally up my street. my installations, totally up my street. my favourite part of this exhibition is the chance to see what my brain does when listening to music. now normal brains are met lots of electrical activity, reduced down to the basics, you could say, they have five main states. for example, normal alertness would likely generate beta waves. and being relaxed or in a light meditation, alpha waves. willing participants where an eeg for real real—time scans, sensors pick up the dominant waveform and use that data to inform the visuals. now as we all experience music differently, the visuals change across each person based on how each mind processes the stimulus. so with

the help of this rain had sat, i can find out what my feelings look like. it feels like staring at our brainwaves could help us staring at our brainwaves could help us understand our moods, so i am not surprised to get a menu by gabe, one of the people here. it is incredibly fulfilling, watching notjust my brain but others as well. it is quite hypnotic, actually. what would you recommend as a desert? (laughs). as the intensity is increased, of the wave goes stronger, that flow pattern will change and it also controls other aspects of that swarm of colour particles, the scale of the particles will change and also they will bloom and decay and blur, a lot of the colours as well.

several as these waves meander between each other then you get this type of animation that plays out. with something like this we are able to show how easy it is to access things you are interested in, particularly music, but as voice becomes more common and ubiquitous, i think there will be, it will change how we listen and how we interact with the content that we are interact with the content that we a re really interested interact with the content that we are really interested in. and experience is everything when it comes to music, many of us use it as a drug—free way to change our mood, andi a drug—free way to change our mood, and i can't wait for more choices on the menu. that was lj having her brainwaves read more action on her head than mine it has been said. and that's it for this week, apart from our big announcement, which is: tickets for this year's click live, the show, are now available. this year we are

coming to dundee in scotland, and we would love to see you there. so if you would like to see us in the flesh, you can apply for tickets now at the website. it's happening next month, we can't wait, and as i say, we would love you to be there as well. in the meantime, thanks for watching and we will see you soon. good morning. this time last week the world weather story was typhoon hagibis. in fact, we were watching this powerful typhoon barrelling its way towards the shores of japan. weather warnings were enforced, several of the rugby world cup matches were cancelled, including the england—france match. i'm pleased to say fast forward seven days and yes we have some

shower cloud across japan but the weather story looks much better for the quarterfinals. in fact, it should be relatively dry, bright and warm, with temperatures into the mid—20s for the england—australia match. i wish i could say the same, however, for the uk on saturday. it does look as though we're going to have plenty of showers, some of them heavy with the odd roll of thunder. but there is an improvement with the second half of the weekend. we are still under this influence of low pressure with this weather front enhancing the rain fall across eastern scotland. will also see plenty of showers out of the west as well. of these showers will boost further inland as we go through the day, perhaps not as many as we have seen across england and, the rain fairly persistent through eastern scotland, drifting down towards the scottish borders as we go through the date and then a northerly breeze getting in behind. so top temperatures on saturday of 10—15 degrees. but as we go to the overnight period, the showers will start to fade away and the northerly wind will start to kick a little bit further south. that is

going to allow temperatures to fall away. low single figures in a few spots, a chillier start to sunday morning but a quieter start to sunday morning. that i'm sure will come as welcome news. in fact, the second half of that we can look drier and there will be fewer showers around as well. a better day for getting out and about. so we start off financially know, that northerly wind would be a future, albeit light, a few showers along the is closed, a little more cloud here, damp and drizzly in places. further south and west we will see a little more sunshine and after that chilly start temperatures will recover 9—14 degrees, the high. again, we could have an issue with some fog and frost through the night, but the story into the early half of the week is high pressure building from the west. there is this weather front that could just be a little bit of a fly in the ointment for the extreme south—east, maybe some rain close to the kent coast. but generally across the uk on monday, that quieter theme of weather is set to build.

there will be light winds, there would be a little bit of fairweather cloud and it will feeljust a little bit cooler. but with the sunshine compensating, hopefully a better feel. 9—14 celsius. take care.

welcome to bbc news. i'm james reynolds. our top stories: turmoil in barcelona — police fire rubber bullets and use tear gas at protesters angry at the jailing of catalan separatist leaders. what's clear is that they are becoming worse and worse. more violent, more protesters on the streets and more response from the police as well, who tonight are trying to protect the national police headquarters which are just down here. super saturday in the british parliament — just hours before mp's decide whether to back borisjohnson's brexit deal.

what matters is mps coming together, across the house tomorrow, to get this thing done. rare criticism of president trump's decision to withdraw troops from syria by a republican party heavyweight — mitch mcconnell calls it a "grave mistake". and making history that's out of this world, two astronauts take part in the first ever all—female spacewalk. police and protestors clashed late into the night in barcelona. 0fficers fired tear gas and rubber bullets at youths — who responded by throwing stones and setting makeshift barricades on fire. during the day 500,000 people held a peaceful demonstration in the spanish city, against the jailing this week of catalan separatist leaders.
