the headlines: president biden has accused republican—controlled states of mounting a dangerous attack on free and fair elections by restricting voting rights. the republican national committee dismissed mr biden's remarks as dishonest. it said republicans were trying to make it easier to vote and harder to cheat. the deployment of hundreds of troops in south africa has failed to prevent a fifth day of violent unrest and looting. at least 72 people have been killed and about 800 have been arrested since protests erupted in response to the jailing of the former president, jacob zuma. and the un world food programme says it needs to sharply increase the quantity of food aid it's delivering to ethiopia's tigray region, where months of fighting has led to widespread hunger. a spokesperson said 100 trucks a day would be needed to reverse what he described as "catastrophic" conditions. a man who killed two
schoolgirls in the 1980s is to be released from prison, despite the government asking for the decision to be reviewed. colin pitchfork has served 33 years injailfor raping and murdering 15—year—olds lynda mann and dawn ashworth. last month, the parole board said it was safe to release the 61—year—old, who was the first murderer to be convicted using dna evidence. now on bbc news, click. this week — the hajj through digital art. sd glasses and sd houses. and how about a glass of wine made with al?
hey, welcome to click! hope you've had a good week. lara, how are you doing? i'm good — just trying to plan for another summer of the unknown! chuckles yep! another one of those is on its way, isn't it? summer is gonna be different for everyone once again this year, and that includes the many muslims who would normally be about to undertake hajj. hajj is the pilgrimage that's made by around 2.5 million muslims every year from all across the globe to mecca, saudi arabia, and this year, it's happening injuly. it's one of the most important acts of faith that a muslim can undertake, and it's said to amaze those who do. but of course, in the last couple of years, the coronavirus has led the saudi authorities to severely limit the number of people who are allowed to visit. however, another way to experience hajj — retelling its story using
the objects and works of art associated with this sacred journey — is about to become available to everyone. and omar mehtab has been taking a look. the first part of my learning journey was to visit the v&a museum in london. and just being here in one of the special exhibitions, as well as the islamic art galleries, something started to stir inside of me — almost a connection to the ancient past. the pilgrimage is to mecca, the birthplace of islam. but many also visit medina, the second holiest city for muslims. now, i've not personally been on hajj — it's supposed to happen at least once in every muslim's lifetime, but only after you're settled and haven't got any debts or obligations. and that's not me at the moment, so i'm not gonna be there anytime soon. however, being here and seeing
these artworks, especially from mecca medina, really makes me — makes me want to learn more about my religion and the culture that surrounds it. this is special. so the next leg in myjourney to learn more has taken me to a large space in south london, where a dozen pieces of art relating to hajj are being digitised. they are from the khalili collections, which includes what's considered to be the largest and most significant group of objects relating to the cultural history of hajj. and its founder is sir david khalili. i didn't start collecting islamic art because it was islamic, because it was the most diverse group of art i've ever seen. every piece had a message. but the story of hajj has never been told through the object that was produced culturally
to honour the place. as you are not allowed to go to mecca medina, but through the experience of collecting objects for the last 50 years of my life, ifeel like i'm there anyhow. i virtually feel the soul of the artists have produced these objects through their beliefs. now, an obvious way to share art is through digitisation. but for it to really work and notjust be 2—dimensional, the art needs to live and breathe — every brushstroke of a painting or every thread of a textile. you really need to bring out what's not visible to the naked eye. take this silk, for example, that's used to cover shrines in the holy mosque in mecca, finally embroidered in both silver— and gold—covered wire. the amount of time, effort and intricacy that's gone into many of these works is a matter of spiritual importance. it's not just art for art's sake, but this is produced for a very particular,
sacred, ritualistic and spiritual purpose. that's where the google art camera, which is capturing the minutiae of detail, comes in. our camera is a custom—built camera, built to capture images of paintings and artworks in super—high resolution. it generates what is called a gigapixel, which is an image of over! billion pixels. so how does it compare to other cameras? well, i've got my phone here, so let's take a picture of it with this. and as you can see here, it looks great. but as soon as you start zooming in, it gets quite pixelated and messy. and the same goes for my personal camera with a 50mm lens. again, no real detail of the gold we know is sitting underneath the silver.
the camera is equipped with a laser and a sonar and using high—frequency sounds, pretty much like a bat, it's able to measure the distance between the camera and the artwork to make sure that the focus is right. and after about 45 minutes, every bit is digitised and a programme stitches it together to generate the full image. an image captured with our camera can unlock information around that artwork, but also unlock the emotional stories around certain artworks and generate, in a way, kind of an augmented experience of the viewing of an artwork. and weeks later, i'm at the final part of my personaljourney — all the captures telling the story of hajj from the khalili collection are there on one platform, using sphere technology. so it puts everything into this big sphere here, creating a 3d—like environment, combining scale with detail. but it's also quite easy to just drag around and zoom into something that interests you. this shirt, actually,
is something that we looked at in real — in real life. wow! a lot of this i didn't actually notice when i saw it up close. the fading and the writing and then the detail, the patterns. it's a — it's a privilege. so this was a painting that we saw, a more modern one. even with this, zoom — zooming right in. just the finer details of the painting, the shadows and the hats. and it works quite similar to google earth in that way, in that you can zoom in and see incredible detail of a specific location — but, in this case, of art. some of these pieces are being shown for the first time. but even in a museum, you can only view it from a distance or when the artwork is inside glass boxes. see, barely anyone has the privilege to see these pieces in real life, let alone this up close. remember the silk cloth used in the holy mosque? here it is, with hints of gold underneath the silver,
not really visible to the naked eye. it's — it's as if the tech is helping me to reach something beyond the art. i can see what sir david meant — that it's another side to it. going on hajj is one thing, but completing that spiritual, that cultural side of it, using this art that's entrenched in the hajj�*s history, is... ..is something special. hello and welcome to the week in tech. it was the week thatjeff bezos stepped down as amazon boss 27 years after founding the online tech giant. china's cyberspace administration ordered the removal of ride—hailing app didi from chinese app stores amidst accusations it's been illegally collecting personal data. and nintendo announced a new $350 nintendo switch games console, complete with a bigger oled screen.
it was also the week that the european space agency showed off an iim—long robotic arm. the era, or european robotic arm, will be the first arm able to walk in space, anchoring itself to fixed points and moving between them. the first pictures of the world's first 3d—printed school in malawi were released. the walls can be erected injust 18 hours. unicef estimates a shortage of 36,000 classrooms across the country and the creators of the new printed schools hope they can help bridge this gap in ten years. and finally this week, a belgian artist is shaming smartphone—obsessed politicians with an ai tracking tool. the machine learning system analyses live—streamed debates of the flemish government. it then posts the guilty parties to twitter and instagram under the handle theflemishscrollers.
the winner of the a! song contest has been revealed — a team from the bay area and california won with this entry, listen to your body choir. # let me ask you a question. # what is it like out there? the song starts as a ballad before the beat drops. # go on. # listen to your body choir. i called john and max from the team to hear more about how they created their half ballad—half banger. i kind of did that on purpose because it was going to be a little bit of a popularity contest. you know, it was going to be voted on by an audience and ajury, and i knew it could not be music by robots for robots. i think that can really quickly devolve into just five minutes of straight screaming white noise, you know, in yourears. so at some point, it has to be
palatable for humans. in our case, one of the things we did was we wanted to create a sort of palette of textures that wouldn't sound like anything we'd heard before. those made up of a lot of those puzzle pieces that i gave back to max and it was sort of this — this challenge of like, 0k. 0k, max, here's the craziest samples that you've probably ever had to work with. but they all — they all are kind of cohesive because they come from this — this theme that we started with, so let's see what you can do with this. # i want to be on time. # up there in the clouds. when you think about al or computers making music, usually we think of like bleep blorp, you know, kind of quantised autotune. what i was surprised by was that the majority of the content we were creating
with the ai, because it's emulating organic sounds and it does not necessarily know what a piano sounds like and like what certain — you know, it doesn't have the same history that we do in our heads, it ended up making sounds that were way more organic. choosing a pair of glasses usually involves rows and rows of them in all shapes, sizes and colours. pick them up, try them on and either you like them or you don't. but the way we choose our glasses in future could be set to change. it's time for personalised 3d—printed frames. 0verproduction is fashion's biggest environmental problem and for eyewear, this means 20—30% stock risk.
and 3d printing can solve this problem by shifting the focus from more inventory—focused production to a more on—demand—oriented production and along the way also solve the problem of fitting — this is a major problem. here in front of me is a range of 3d—printed glasses. they come in a variety of colours, too. now, the idea is that you choose the style that you think will suit you best. no. and from there, a pair can be 3d—printed that should fit you perfectly. so using a tablet and three cameras, yourface is 3d scanned in store to create an avatar to try on the eyewear. the system's algorithm is measuring you up for glasses that should not only fit
you perfectly in appearance, but also in doing theirjob well. this process should eventually be entirely possible on a mobile phone. typically, the measurements that we would take would be the pupil distance, the distance between the two pupils, the heights of the pupils, so where the pupils sit within the lens... ok, so i need to label my right pupil. there we go. left pupil. right temple... the vertex distance, so the distance from the surface of the eye to the back of the lens. we'd also have look at the wrap of the frame as well, so we can see how much of a wrap the frame had. so your trip here may only need to be to get your eyes tested, unless you want to feel the product first, or long for an optician's opinion. i can choose the colour of the arms — let's go for silver, they look nice. now i can order them.
and the future could also see more choice. 3d printing now is a technology where you can print in more than 15 materials. so in the future we will print goods, frames, in transparency material, in bio material, in metal material. so we are at the beginning of this industrial revolution. the aim here is what is being called mass customisation — where by making lots of personalised products, the cost can be kept down. and although these glasses do start at £160, which is similar to many others on the shelves, that rises with some of the options. but beyond all of this, and the sustainability element, for this to really work, the finished product needs to prove to be the perfect fit. 0k, well your glasses have arrived now, do you want to pop them on for us?
they are super light and really comfortable, but the thing that i noticed more than anything was in the shop when i was trying them on, everything looked a bit wonky. i always have this with sunglasses, where one eyebrow shows and the other doesn't, so clearly i have a wonky face. and these glasses seem to fix the issue. the glasses are maybe as wonky as my face... crosstalk. i never thought of you as having a wonky face before but i will have to take a closer look in future. i tell you what, do you fancy something else that is 3d printed? it is slightly bigger than a pair of glasses though. what is it? it's a house. in california, you will be unsurprised to hear, 3d printed houses are a thing — kind of. these are houses that are partly constructed using 3d printing techniques, and here is james clayton to tell us more. california, like many places around the world, has a housing problem. too few homes has led to sky—high prices, and that has also helped contribute to the state's
homelessness problem. step in 3d printing. you can make pretty much anything with a 3d printer these days, from guns to iphone cases — so 3d printing houses help solve california's housing crisis? well, one company here in oakland thinks that it can, and it has already started to 3d print components of houses. yeah, so i think 3d printing has a huge opportunity to help solve the housing crisis. obviously i am a little bit biased. mighty buildings has won a contract to build what they say is the world's first community of zero carbon 3d houses in rancho mirage, in southern california. we are going to be deploying a combination of three—bedroom two—bath single family homes. these houses are not small, so how can they build such big structures out of plastic? what we have done is we've leveraged a proprietary 3d printing technology we have created with the material called lightstone, which is a thermostatic composite, so it's kind of a synthetic stone, that cures using light,
so that means that it cures almost instantly, which allows it to support its own weight, meaning we can do curves, unsupported spans and all sorts of things you can't really do with concrete or other materials. the plan isn't to build an entire house, it is to build different panels and then on—site try and fix them together like lego. the question i had, though, is aren't mighty buildings just building prefab houses under a different name? we are totally prefab, we make no bones about it and we are proud to be prefab. but the cool thing is we are able to help prefab lead into its promise in a way it never has, because one of the issues with prefab to date is it usually involves taking additional construction and putting it under a roof, which gives you some gains but not all that they are capable of. but also usually means needing a lot of space, which means you are usually going to be far away from the housing demand.
our vision is to deploy these mighty factories around the country and the world in areas where we have demands and we have partners, and minimise those logistics. mighty buildings have mighty ambitions, but before you start thinking this could solve the housing crisis in the near future, think again. firstly mighty buildings currently sells a hybrid 3d house, but that is pushing it a bit. when it comes to 3d printing there is a lot of hype, but in this unit, the only thing that is 3d printed is this section here. everything else here is built through traditional housing techniques. the houses that it plans to build in rancho mirage will use 3d printing for the building's walls, but the development is only 15 houses. the houses themselves are being sold for more than $500,000, so you will need a fair bit of cash to buy one, and they don't actually have permission to build yet. mighty buildings certainly has potential, and many in the building industry will be looking on with interest. but is this the answer to today's housing problems? well, no, not yet.
that was james. now as we said, summer season is upon us and many of us will be getting itchy feet, and wishing we could go on holiday abroad. but alas, here we are. so we're bringing you a story from far away — really far away. when nick kwek was in south australia, naturally he wanted to test some of the produce — of course he did. over half of all the wine grown in australia is grown here, in south australia. the industry is worth $35 billion to the country every year. and where there is wine, i must surely follow. so i have strapped on someone else�*s wellies and set forth in the name ofjournalism. changing climate conditions and water shortages means that growers here are turning to tech to help out the humble grape.
we were in very dry parts of australia and and irrigated viticulture needs very fine tuned management to successfully grow high quality commercial quantities of grapes. researchers here at the university of adelaide are developing a smart system so vintners can keep better tabs on their produce. ok, so that's where the leak is. they are deploying various sensors that can be monitored remotely. so what we have here is a flow sensor, connected to a radio unit that transmits the data in real—time. this one is the soil moisture probe, basically mount this thing right underneath the soil. we actually have the equivalent of a stethoscope hearing the water in the plant going up and being taken up by the plant. and they are using thermal imaging cameras to monitor their irrigation. just with a normal camera you wouldn't be able to see that leak, but with this thermal imaging it now shows it very clearly. and also how severe it is.
all the gathered data is fed into the custom—built, exceedingly smart vitiviser platform. you can call it a super ai brain, which can process to understand and can assess the situation to see whether it is all doing well or something we need to manipulate or change or to intervene. and also can predict what the yield is going to be. it can draw in information on how much water is being used at the moment within the vineyard. is there a leak in that vineyard, has a drone been deployed to find exactly where that leak is, and has it been stopped? we also have information on when the vines will mature, and therefore the farmer can go and order or perhaps the dashboard can help pre—order the machinery required to come at a time for the harvest. it will work out the growing rate for grapes at the time and factor in labour and water costs too. and of course, they are
developing an artificial intelligent rover which will autonomously patrol the rows, understand the current conditions of the vines and raise the alarm. it sent a text message to the growers saying you may want to reduce your water irrigation, save your water bill, maybe give you better quality and reduce the chance for disease. because if overgrown canopy has lost ventilation, it is bad for you. also through the cameras we can accurately predict the pruning rate, how much you want to prune back the vine, which is a crucial step for the growers. the project is backed by riverland wine and the government. we see technology playing a critical role in helping to forecast issues, if you see a frost coming or understand when a dry spell is going to settle in, and make sure you have got your irrigation decisions as well set up as possible. the team says their work
will ultimately lead to a better beverage, but the proof will be in the...bottle? cheers, nick, ithink i will treat myself to a glass of red after that. i think i willjust stick to the fruit juice unless they can create wine that doesn't give you a hangover, now that i would be interested in. because it is not about you, is it, it is the wine's fault. anotherfilm for another time i think. that is it from us by now. as ever you can keep up with the team on social media, find us on youtube, instagram, facebook and twitter at @bbcclick. thanks for watching and we will see you soon. bye— bye. hello there. summer weather is increasingly set to take hold over the next few days.
it is looking largely dry. we'll see increasing amounts of sunshine and increasing temperatures as well, and it is all because of high pressure. currently, this area of high pressure is sitting to the south—west of us, but it is going to build towards the uk over the next few days, hence the increasing amounts of sunshine and those higher temperatures as well. but actually, through wednesday, many spots will see a decent amount of sunshine. we will have quite a lot of cloud through the morning across some eastern parts of scotland and eastern england, tending to retreat towards the coast through the day, and also, more cloud into northern ireland and western scotland. and actually, as that cloud thickens up through the afternoon, it could even produce the odd spot of drizzle. but elsewhere, some good spells of sunshine. temperatures in the sunniest spots up to 2a or 25 degrees. a bit breezy for north—western areas and also for some eastern coasts. now, as we head through wednesday night into thursday, we will see more cloud rolling down across northern ireland and scotland, getting into northern england and wales by the end of the night.
clear spells further south, a pretty mild night — 11—15 degrees in most places. into thursday, we are going to see more in the way of cloud pushing southwards down into england and wales. there'll be some spells of sunshine and certainly, some brighter conditions developing for northern ireland and for scotland, and in the best of the sunshine, temperatures again getting up to around 2a or 25 degrees. and for friday, many spots can expect to see plenty of blue sky and sunshine. a bit more cloud at this stage across north—western parts of scotland, northern ireland, but certainly more cloud across the northern isles. the sunnier skies further south lifting those temperatures up to 25—26, maybe at this stage, up to 27 degrees. and that sets us up for the weekend because our area of high pressure is going to become firmly established across the uk, bringing lots of dry weather, lots of sunshine. you can see frontal systems close to the far north perhaps giving a bit more cloud at times, but with our high pressure in place, we can expect some pretty warm weather through both
