this is bbc news, the headlines tributes have been paid to the first victim to be named in the london bridge attack. cambridge graduate jack merritt, was running a prisoner rehabilitation conference — to which his attacker had been invited. the british government says the licence conditions of every convicted terrorist released from prison in england and wales are to be reviewed. a maltese businessman has been charged with complicity in the murder of the journalist daphne ca ruana galizia. yorgen fenech was arrested last week as he attempted to leave malta on his yacht. he has pleaded not guilty to the charges. hundreds of climate campaigners in eastern germany have occupied several opencast coal mines to demand their closure. police say three officers were injured when they tried to remove demonstrators from one of the sites. the protesters have rejected the government's plan to phase out

coal mining by 2038 — and instead want the industry to be closed down immediately. thousands ofjobs in the region depend on the mines. now on bbc news, it's time for click. this week — long jumps, a soft landing, high fives... high five — a blind girl high five! ..and squeaky toys. december 3 marks the un international day of persons with

disabilities. and each year on click we use the occasion to look at some of the latest technology that's helping to change the lives of disabled people. this is the beazley designs of the year exhibition at the design museum london, which feature some great examples of inclusive design. this is mysleeve, silicon grips that make crutches more comfortable. they're also magnetic so they snap together and can be held in one hand. thisables is a 3—d printable add—on that makes small buttons bigger and more accessible. and the canguro is a concept mobility robot which can carry your shopping for you. one area of cutting—edge design and research which is playing an ever increasing role is prosthetics, particularly in the world of sports. this is paul carter. hello. you've been looking at some of the latest prosthetics for us, haven't you?

i have. and you started in a place that seems pretty non obvious to me. that's right. they went to reykjavik in iceland and i went to see the manufacturing process and the story behind the iconic running blade, the prosthetic running blade which is now synonymous with paralympic sport. and what people might not realise that there is a huge amount of research and design which goes into making the blades, but also developing them and testing them to make them faster in the future. right, and you've got a pair of blades yourself. i do. i'm very much a non—paralympian. i'm not really built for running. so i decided to leave this one up to the professionals. here at the headquarters of prosthetics company ossa in iceland... ..they‘ve gathered a team of serious paralympic athletes for some even more serious testing. these athletes have a stack of medals, world, and national between them. and they're all major contenders at the 2020 paralympic games in

tokyo. they're providing 0ssa with feedback and data about the performance of their prosthetics, which, it's hoped, will lead to better performing blades in the future. we're going into a lot of biomechanical analysis. we're looking into different ways of applying the carbon fibre techniques and trying those out. it's a bit of trial and error, obviously, in all of it as well. first invented in 1976, blades have been commonplace in paralympic sports since the mid—90s. and they've come a long way. so i've got a selection of running blades here on the table in front of me. and different iterations through the years. and the one thing that really strikes me is, really, it's kind of been evolution more than revolution. i mean, this was the original design which is now about 20 or 30 years old, and it's kind of got that classic sort of c shape that you can recognise.

i mean, these are the blades that i personally have at home — i need to wear them more than i do — this is the flex foot. which, again, was a slight moderation on the original design. and then from there we progressed to this one, which introduced this bend in the back side which spreads the load, when you're actually pushing down it spreads the load. i mean, they don't actually look that flexible, because i'm not strong enough to bend them, but these actually take quite a lot of force and all of that force is distributed along the back here. and fast forward all the way up to today's cheetah pro, which is this one, it's not i million miles away, but it's come through quite a few iterations to get there. but i couldn't come all the way to iceland without actually seeing how they're made. and the design and manufacturing process is more involved than you might think. wow.

i'm used to hospital workshop, which are kind of usually one man and an allen key. this is insane. so this is sheets of carbon fibre fabric. you can see it on this machine here being cut into strips. it's actually mind blowing to believe that these really thin little pieces of fabricjust here will eventually turn into one of these. what's amazing is that you can actually see the process, following it all the way through. you've got the start of the process here and you've got some moulds on the left, which we're not allowed to show you. this is essentially a giant oven and once they're laminated and pressed together and covered in the resin, they go into one of these, which applies temperature, but also pressure, which is really important because that's what condenses these and

gives them their solidity. i wouldn't much fancy getting inside one of these things. i'd probably end up with the bends. i was fitted with a blade in five minutes and i started running on the hallway in 0ssa for the first time in, like, 13 years or something, 12—13 years. and it was a day that i will always remember. how did that feel running for the first time? running for the first time after the amputation was like finding the wind in the airagain. i have to, like, be honest. there were tears — there were tears. each blade is customised to every athlete. taking into consideration their physical attributes, running style, and forces they're applying, as well as this sport that they participate in. we're dealing on the biomechanical side with the most advanced gate laps that are available. so we're talking about vicon

systems, force plates, that are basically telling us, objectifying what it is that the athletes are trying to tell us as well. they're telling us what it is the foot is or isn't doing, to make sure we understand where we can potentially tweak. the design process draws parallels with that of motorsport, where changes are being considered that can show fractions of a second or add small distances to performances. and what was that transition like to having something that's been kinda personalised to you? it was really nice to have, because i could give feedback about how i felt and what i would like to feel. it really felt like we had the room to search for something that fits my personal running style and it's different for everybody, so there's no, like, one golden rule regarding blades and it's fun to realise that and that you can reallyjust, you don't have to do what the paralympic champion is doing, because that might not even be the best for me. so it's good to have the opportunity

to search for the right blades with a team of people around me. i switched to blades two months ago, category—wise, i went a full category different. so we're still not — well, i'm sure now that i have the right blades, but it's only been two months. so within the four years i've been doing this now, we've been changing, we've been adjusting the alignment, and the alignment in winter training is different than during races, so it's a constant change and development. it's never done. the new ones, they're helping the athletes a lot. the times are getting better, people are getting faster. so it has something to do with the prosthesis and also people are getting more professional in the paralympian world. blades are essentially springs. they can't return any more energy than is put into them, but concerns have been raised about just how far development can take us. is there a risk we go

beyond merely the physical capabilities of the athletes? a carbon fibre blade is not able to provide active positive energy. and that is what the human leg does. so if you look at itjust in that simple manner, you're always going to be slightly underperforming if you're reliant on a blade that is not able, like a muscle, to produce 200%—300% of the power if you're contracting it in a sports activity. could we potentially integrate structures that could make a higher level of propulsion? there might be an opportunity for that. at this stage that's not at the order. we're not looking for that. we're looking to get people to maximise their performance, with a device that supports them as well possible. that i would say is definitely giving them the fair opportunity to compete. hello and welcome to the week in tech.

it was the week that ride hailing firm uber was told it won't have its london license renewed due to what transport for london called repeated safety failures. uber is appealing the decision. google fired four workers known as the thanksgiving four, over what it calls data security and employee safety. other employees accused the company of punishing them for speaking out. spot the robotic dog has been working alongside massachusetts state police. boston dynamics' a—legged friend has been trialled for the past three months, helping with live incidents as well as training runs. staff at nasa have been busy bees. they have released the first astrobees on the international space station to help astronauts keep the place clean. these worker bee robots clean the air and will seek out a charging station when they're exhausted. and, finally, the royal navy will be flying a different kind ofjet from the deck of hms queen

elizabeth. this jet pack, made by british firm gravity, allows the wearer to fly up to 32 mph for 5—10 minutes. i'm guessing you'd want know if it was going to be five or ten minutes in advance, though, wouldn't you ? earlier this year, at click live at the hay festival, maisy was a part of one of our most memorable moments. maisy, are they working? yeah. i can see your microphone. and i can see that you're smiling. and i can see the buttons on your shirt. take a look at the audience. they're waving. i can see there's a lady in the front with a red jacket. the guy next to her is wearing stripes. oh my god, it's so amazing. following that episode,

many of you got in touch to ask whether maisy got to keep the givevision glasses? well, we're happy to say that she did. and we asked her what she's been up to since that show. so what have you used the headset for since? i suppose the most exciting thing for me was going to see my favourite singer, pink, live in cardiff. i bet she looked epic. it was the most incredible night ever. i cried so much and danced so much and just had a fantastic time. it's so amazing what technology can do for us blind girls, isn't it? it's incredible. it really is. we wanted to get maisy back on click so we teamed her up with journalist lucy edwards, who's also blind, to take us on a tech tour of blind life and to test some new innovations along the way. i lost my sight seven years ago. navigating the world can feel

like a huge challenge, even with my gorgeous guide dog, 0lga. i usually use my guide dog willow to get around, but today we're trying out a new device — wewalk smart cane. i think 0lga's a bit confused with the cane. the device has a round sensor to detect obstacles. i've paired it with my smart phone and airpods to send me directions. so my airpods pick up the information from my phone and the navigation system reads it out to me. when we got there it said, "starbucks now on your right". and, yeah. by then we could smell it anyway, couldn't we? when i was using the cane it was always vibrating. that's buzzing a lot. is it? yeah, the buzzing got really quick. so i knew that i was in front of something that was quite a large obstacle. this might be an improvement

for some cane users, but personally i've found the feedback slightly overwhelming. i could imagine it could probably get quite difficult to detect what's important and what's not important. i was excited to show maisy an app named microsoft soundscape that uses 3—d sound to point you in the right direction. you can hear the sound as if it's around you and it's like you're in the software almost. phone: facing south-west along world piazza. when you're tuned into the app, it will name nearby shops and restaurants. it even highlights what's on the pavement. is there bike parking in front of us? 0ne useful tool is the ability to set an audio beacon, say, if you want to find your local supermarket. 65 metres west. it's making this tip—tap sound. tapping sounds help guide us in the right direction, although we did manage to walk past the shop door.

i think you don't quite believe it's to the right of you. at least we had our guide dogs to help us find the entrance. at home, some of the simplest tech can actually be the most useful. beeping. but big tech companies, like apple, google and amazon, are also trying to make their technology better for people like me. most of the time, i use my smartphone and apple watch. it's so great that it can connect to my apple tv and you can get it to play your favourite moments. lots of smart speakers now have audio book services. one new and particularly unusual audiobook is called unseen — it's the first ever audio comic book. when you hear this sound... that is so cool. cover — the word "unseen" in bold letters. 0h, amazing! no—one ever does that, that's the typeface. describing the pictures and each

panel, which is the big part of comic books. i can't wait for unseen‘s creator, chad allen, to release the next segment. i don't know who the hell you are! i do not know who the hell you are! oh, it's loading. i was also excited to try a new device from bristol braille technology. this device i have in front of me is called the canute and this is the very first ever several—line braille display. it sounds like a typewriter! using buttons at the base of the device, you can upload books, pdfs and documents. the multi—line layer is great forfeeling diagrams. it's an easier and quicker way to read. that's nice. you can use something like this and not have audio on, constantly all the time. are we reading braille? yes. i was even more impressed with the next device we tried. a pair of 0rcam smartglasses. these use a camera and artificial intelligence to read the text around

you. and you can use touch, voice and gesture commands to change set its setting. so, what are you doing, maisie? so i have a magazine and if i point ata line... app reads: i always say that there are... it's reading it! we surprised maisie with a book from one of her favourite authors. kaitlyn dunnett. cool! the 0rcam tells you the time. the time is 3:29pm. yay! and can name who is standing in front of you. of course, i wanted to see if we could get it to recognise maisy. the device does this by remembering the unique points of a person's face, a bit like a map. maisy. just flip my head around. oh, yeah!

highfive! blind girl high five. we also tried a new feature — the ability to scan food product barcodes. this was a hit. tomato cup of soup. remember to hold your item about a foot above the counter top. alexa, what am i holding? i was really excited to test the new amazon echo show feature. you hold a food item in front of the screen camera and move it around until the device tells you what the item is. it was difficult knowing whether the item was centre screen and this threw up some less than accurate results. show me another side. it looks like vanilla coca—cola... oh, my god. that's cool. i have done that so many times — like, i've picked up cherry diet coke by mistake. yeah! we also have been told that that wasn't vanilla coca—cola, and just regular coca—cola. you would have to really nail getting your snapshots correct to find this useful.

it was so great to try all the technology throughout the day. the wider the choice of tech, the better for everyone. not everything today was a complete success, but the impact that blind technology can have continues to surprise me. i am really excited about the future of accessibility tech. some fantastic innovations there. and one thing becoming clear in this programme isjust how much is out there enabling people to be more empowered and to live more independently. yeah, and for people with learning disabilities, for example, there are plenty of innovations to help them do just that. paul has been to meet someone for whom the internet is helping to make life just that little bit more easy. this is adam. adam has down‘s syndrome and lives in his own home, which includes some specially designed technology to allow him to live more independently.

here he is using a tablet that contains a range of bespoke applications to help him with tasks in everyday life. in this instance, cooking. can you show me what you've got on here, adam? app: sift three cups of plain flour into a big mixing bowl. make a well in the centre of the flour. here, it shows step—by—step instructions with pictures. but the technology goes much further than just recipes. it's part of a project called connected living — a partnership between the learning disability charity mancap and telecoms company vodafone. the platform utilises a range of technologies bundled together under one roof — literally. iam afraid. from smart home devices and iot—based sensors to more simple reminders, to—do lists and instructions. a lot of the elements in adam's house, all on iot, international things, things that are connected, machines that are connected to each other,

that provide long—term connectivity. a lot of it is stuff that people are familiar with. smart lighting, smart locks, not particularly new concepts, but what we have done is we have packaged it altogether and put it into this user interface which has been tailored very specifically so it is user—friendly and it is intuitive to use. we started off with a very, very long list of things — and these can be quite small things — but things that people might want to achieve and then we gave the list to vodafone to find technological solutions. we whittled it down to the things we felt and we heard were most commonly going to be of importance to people. technology is in all our lives at the moment nowadays and will continue to be so. so we want to make sure that people with learning disabilities are not disadvantaged by not being able to access technology. it is designed to be customisable

to each individual user, with the hardware and software tailored to their needs and personal abilities. app: i am thirsty. the platform blends smart home technologies with things adam can use outside the home too, such as video calling a support worker if he needs assistance or as a communication aid. what would you do with the options on this screen? hi there, you all right? so what would you do with the options on the screen? so you can tell them where you want to go. which are your favourite? what do you like to do the most? let's go to the pub. sounds good to me. is that good? do you like that? that's good!

we like tech too! there are 4.1 million people in the uk with learning disabilities who could use, this but also there are wider applications. if you think about people who go into homes as they get older, they still want to be independent, they still need their flexibility and this can help them. you and i, we want to be independent, we want to do our own thing and actually, if technology can help people to do that, thenit means that you have greater control, you are feeling more independent and the amount of confidence that is really increasing in people is fantastic. most importantly of all, though, how does adam feel about his smart connected home? supported, yeah. supported, mmm. yeah. that was adam and his mum. truly lovely. and we will continue to keep across all of this area of inclusive design and technology throughout

the year, as we always do on click. in the meantime, you can contact us with your thoughts about what you have seen. we live on instagram, youtube, twitter and facebook. so get in touch with us, and you can find us there all throughout the week. thanks very much for watching and we will see you soon. hello there. good morning. signs of change towards the end of the coming week. but new month, same old cold air across the uk. we're dominated by this cold area of high pressure. the last of the mild air that was towards the south—west and the channel islands, together with that weather front which brought some pockets of light rain, that's moving away now, getting blown away by the breeze. head further north, though,

there are still some patches of fog through the midlands, east wales, maybe the vale of york, around the solway firth, and into the central belt of scotland. a few showers around the coasts of northern ireland and the far north of scotland, but generally the northern half of the uk starting cold and frosty widely. there's more patchy frost further south where we've got that breeze. and that will tend to lift the mist and fog through the midlands and wales much more quickly. further north, a few patches may linger until the middle part of the day, at least. but generally it becomes dry and sunny. got a few showers on that keener breeze across the north of scotland, down those north sea coasts, and particularly later into kent. these are the temperatures for the first day of december. similar to what we had on saturday. not quite as chilly as it was, though, perhaps, through the midlands with more sunshine here as there will be in the south—west of england where it's going to be dry. high pressure, cold air continues overnight as we head into monday. but signs of change into the north—west. 0ur air beginning to come in from the atlantic. a patchy frost for scotland and northern ireland on monday morning it won't be

as cold, with the frost more widely for england and wales. after a starry night we're going to have plenty of sunshine on monday and lighter winds. south—westerly breezes blow a bit more cloud into northern ireland and particularly into scotland, where we'll see some pockets of rain, especially in the north of the country, where temperatures may actually get into double figures. for many, temperatures are going to be at sixes and sevens. we've got high pressure dominating then at the moment. gradually, as we head into tuesday and wednesday, it slips away into continental europe, getting eroded by these milder atlantic winds. with higher pressure close to southern parts of england where the winds are lighter, skies clear, we've got to maybe worry about some mist, fog, and low cloud in the morning. that could linger, actually, until around about lunchtime before tending to lift and break up. it should be a dry day on tuesday, even across the north of scotland. some sunshine for northern ireland. and those temperatures typically at sixes and sevens once again. another chilly sort of day, i think, on wednesday.

gradually, later on in the week, it turns milder, it turns windier, and we'll see some patchy rain, mainly in the north and west.

this is bbc world news. i'm james reynolds. our top stories: the first victim of the london bridge terror attack to be named is jack merritt, killed while running a prisoner rehabilitation conference to which his assailant was invited. britain's ministry ofjustice launches an urgent review of convicted terrorists released from prison. a prominent maltese businessman is charged with complicity in the murder of the investigative journalist, daphne caruana galizia. hundreds of climate campaigners in eastern germany occupy open—cast

coal mines to demand their immediate closure. hello, and welcome to bbc news. the first of the victims of friday's terror attack in central london has been named as jack merritt, a cambridge graduate who was helping to coordinate a conference on prisoner rehabilitation near london bridge. he was one of two people killed by 28—year—old usman khan, a former prisoner who'd been convicted of terrorism offences. here's our home affairs correspondent daniel sandford. 25 years old and with the sense of adventure, jack merritt had a masters from cambridge university. his father said today he was a beautiful spirit who always took the side of the underdog. yesterday, he was stabbed to death in a frenzied attack by a former prisoner

at a conference that he'd helped organise.
