britain has officially left the european union, bringing an end to nearly half a century of membership. the moment of departure triggered celebrations by brexit supporters around the country, with many people waving union flags. for others though it was a sad moment. there have been muted counter—rallies by people who wanted to remain in the eu, saying they feel disenfranchised by the move. us senators have voted against calling witnesses at donald trump's impeachment trial, a move which brings the end of the process much closer. the democrats failed to persuade enough republicans that witness testimony was necessary. the authorities in the chinese province of huh bay have declared 1,300 new cases of the coronavirus, and confirm at least 45 more deaths. the us has announced it will bar foreigners who have been to china from entering the country.

now on bbc news: click. this week, high impact smashes. the cgi secrets of youth. and greener fashion through clothing hire and pa nts fashion through clothing hire and pants on fire. over the last decade or so, fashion has gotten faster. cutting—edge design techniques coupled with a huge reduction in the cost of production and the growing success of online clothing sites means new

designs and trends can be turned into low—cost clothing much quicker than just once a season. as a result, more than 1 than just once a season. as a result, more than1 million than just once a season. as a result, more than 1 million tons of close are now bought every year in the uk. the thing is, as fast fashion has grown, so has fashion waste. with everyone wanting to update their wardrobes more regularly these days, it means we're throwing away hundreds of thousands of tons of close every year. as the high—street piles them high and pile them cheap, displace us to do the same. the environment and the waste produced by a fast fashion is just one issue facing the industry. another is how these clothes are made in the first place. in order for us to get such cheap fashion, much of it is made in countries where lab costs are low. bangladesh isa where lab costs are low. bangladesh is a case in point. it employs millions of people in this industry

but is faced with regular calls to improve its working conditions. some now think that adding robots to the factories may help but at what cost? this is a very live example of the automation versus jobs argument that we hear so much about. jane has been to bangladesh and has been given a very rare access to the industry. bangladesh is second only to china in producing clothing for the world. its ready—made garment industry is critical to the economic success of the country, providing jobs for over 4 million people, the majority of whom are women. this man is on a mission to transform the future of fashion here, starting with his sternum factory in the southern port city. the world focused its attention on bangladesh's garment industry after

the rana plaza disaster in 2013 when it nearly 12,000 people were killed when the building collapsed. the eight story complex house five garment factories supplying clothing to international brands. did you go to international brands. did you go to the plaza when it happens?” immediately, it was 11:30 a.m., something like that. i took my shuttle and run away and... mustafa's focuses not only on the social well—being on his workers but on bringing environmentally sustainable technology and innovation to the factory, including

a design studio where an in—house tea m a design studio where an in—house team creates new styles of genes to show international buyers. this is oui’ show international buyers. this is our innovation and developments room where we keep on producing our products and keep things over here so products and keep things over here so that when the clients from all over the world come here, they can see all the innovation going on in the industry and one time. who has visited your lab? this product that we see here would be seen in the uk and the high—street? the process of distressing denim is laborious, workers here are sending genes by hand to create holes and whiskers on the fabric. it is

hazardous, laundry, especiallya hazardous, laundry, especiallya hazardous area. the main hazard is... a high—tech alternative to hand sanding is now being used in the factory that requires far fewer workers. this laser machine cost 200,000 euros and can be operated by one person in a clean and air—conditioned room with no dust. it uses pre— programmes designed to automate the work the humans are doing next door, from burning holes into genes to creating the whisker patterns down the legs.

so 2500... a machine also won't take to the street and protest against low wages 01’ street and protest against low wages or poor working conditions. last year, bangladesh saw civil unrest from garment workers at other factories, demanding better treatment from their employers. and introducing more automation could have the unintended consequence of moving jobs away from occurrence manufacturing hubs. this is already

happening in the united states. back in dhaka, he recognises the need to engage international retailers in these important discussions.” engage international retailers in these important discussions. i think these important discussions. i think the solutions for all of us sitting in the room today... we joined him at two of his conferences, the denim expo and the sustainable apparel forum. technology is a big theme here and companies like this one have advanced laser machines for garment finishing and an italian company provides high—tech laundry. it has to be a technological industry and not any more human driven industry.

something this will open up new possibilities for bangladesh's workers. they can have a betterjob, for example, they can become an engineer and learn how to use the machine. they can become a designer. do you think it is feasible for 4 million low skilled workers? yes, it is going to create otherjobs in other industries. for sure, is going to create otherjobs in other industries. forsure, i is going to create otherjobs in other industries. for sure, i see it asa other industries. for sure, i see it as a positive thing. but others are not so sure. i don't think automation is going to benefit any worker in any industry. automation is basically a replacement of the worker by a machine which the owners of factories would really love and it stabilises costs. it stabilises working conditions. it solves a lot of problems. and the women who make up of problems. and the women who make up the majority of the battery workers may be disproportionately affected by these advances. so really, you prefer that these women have jobs that automation. of

course. we have 5 billion people working on bangladesh apparel industries... estimates vary as to how manyjobs automation will displace in the industry but some recent reports say up industry but some recent reports say up to 80% of simple garment work could be at risk in asia in the next five years. the creation of new machines has brought a once distance

prospect of automating workflow in garment factories sharply into focus. hello and welcome to the week in technology. it was the week microsoft had a deja vu moment issuing a second final windows seven update just days after saying there would be no more patches for the decade—old operating system. the uk decided it would permit the use of 1—way tack in its 56 network despite pressure from the us. restrictions limit the chinese giant. 15 and a football teams were struck by an hacker group. the groups that are targeted twitter and facebook accou nts targeted twitter and facebook a ccou nts to targeted twitter and facebook accounts to show that internet security was still open. in london, the metropolitan police is rolling out its first live operational facial recognition cameras amidst scepticism from human rights groups. police say it is al who identify suspects wanted for serious crimes with 70% accuracy yet one watchdog previously warned, if our less

accurate result. british developers issued a warning to players of its pandemic game played inc after linking a spike in popularity to china's coronavirus outbreak. the studio reminded fans that while the game is realistic, concerned individuals should turn to real health authorities like the world health organization. and finally, retro arcade games like aspirates could be back with a crash as vintage games that make up atari makes an unlikely turn into the hotel business, promising vr and ar spaces alongside game streaming studios. who fancies a blast from the past with a side of room service? the idea of renting close, clovis is nothing new, neither is doing online. companies like this one have beenin online. companies like this one have been in the us for over a decade and

has dell met stress in the uk. but the popularity of many of these platforms has rocketed since the newfound interest in sustainability has made throwaway fashion feel like a bit ofa has made throwaway fashion feel like a bit of a rubbish idea. but the desire for an evolving wardrobe hasn't gone away. so i've been taking a look at a few of the uk start—ups that are using an extra bit of technology to bring this idea upper level. this app brings peer—to—peer lending to mobile phones, adding a spot of ai peer—to—peer lending to mobile phones, adding a spot of al to the mix. we have got to make machine learning tools that we've built. the first one is to show listers or lenders when they are listing items. they take retail photos are matters and infringement of copyright laws. the second thing we have built is helping people to tube rate looks. if you've rented a black dress, we will match a pair of green shoes and a green bag with it. next up, the

company is working on machine learning to overcome the issue of variable sizing. over 8000 users or rotators as they are known, like cat here, already benefiting from adding an extra spot of cash from their belly one fred's or some wardrobe variability themselves.” belly one fred's or some wardrobe variability themselves. i got into the whole sustainability and renting thing and buying secondhand in the middle of last year and then i found there were some rental platforms and i was like, that is amazing. i have a lot of stuff and all of my friends wa nt to a lot of stuff and all of my friends want to borrow things for weddings and events and i was like, maze or make some money for it. what percentage of the price of the address are you renting it for? there is a suggestion in the upper but i usually... i think if the dress is like $330, is between 12 and £15 a day and then you offer a discount for a week or a month, they going away for ages. when you offer

them 50 or 70% discount. i done it a few times and you make back money. one apple hopes to create an entire ecosystem around this idea. save your wardrobe allows you to create a digital version of your entire wardrobe. to do this, some of this will be a matter of it scanning your e—mailfor receipts will be a matter of it scanning your e—mail for receipts for clothing. other items you may need to photograph to input. you will also then make a note of how regularly you form them. now that means that if there are any items in the back of your wardrobe that you haven't touched for a while, it could suggest ideas on as well as that rental element providing a partnership with higher rotation, cleaning companies and government preparers will also be recommended and linked. we create a system of services as a way to recycle a nd system of services as a way to recycle and extend the life of garments. it does sound time—consuming. garments. it does sound

time-consuming. we managed to squeeze the time to a few seconds when it comes to e—mail scanning. it should take a matter of seconds for the wardrobe and the computer vision is strong enough to categorise the colour, category and brand. you need to add the size yourself. basically we are doing what's by the status modify is doing with your music. we are doing what's by the status modify is doing with your musicm the idea of tracking our wardrobes likely track out steps takes off, maybe passing fashions can become a thing of the past. that was lara. we are going to change tack now. this weekend sees american football's showpiece event — the super bowl. watched by millions across the us and around the world, the spot is

starting to gain popularity in the uk as well. in fact, london plays host to several matches throughout the year. from a tech point of view, this fast paced aggressive sport is swimming in data and being able to insta ntly swimming in data and being able to i nsta ntly a nalyse swimming in data and being able to instantly analyse it, whether you area instantly analyse it, whether you are a coach or a player, is key to the action. earlier in the season, we went to check it all out when the houston texans played again. 100 yea rs of houston texans played again. 100 years of nfl. busy reflecting on the history of the spot. but it is also looking to the future through a partnership went technology giant, microsoft. —— west. alongside the speed, showmanship, violence and beauty of the game, the spot is being transformed by technology.

microsoft has created a purpose—built tablet to aid players and coaches with instant tactical information which, in a game that is essentially like chess but with real people, minor adjustments can be the difference between winning and losing. these tablets are standardised for all 32 teams in the nfl. each team has 25 of them. 13 on the sidelines and 12 in the coaches booth. you can turn out the same play-by-play booth. you can turn out the same play—by—play at different angles around the peach stop the screen is around the peach stop the screen is a lot brighter and a bit more rugged just in case tensioned run high and the coaches decide to chuck it down into the pit. with more information and data available to plays immediately on the sideline, how does it affect the game? the tempo isa does it affect the game? the tempo is a lot faster. the offence is

changing constantly. the defence is doing the same thing so the speed and temper of the game of the chess match moves much quicker. up here we are anything coaches booth and before they use to get a birds eye view of things and write it all down on paper and take that paper down to the dressing room to be able to communicate with the team. from up here, they can make the changes from the tablet was not at half—time they run down, go to the profile and show the team. the nfl believe this is really helping teams. when you can make an adjustment in real time, thenit make an adjustment in real time, then it becomes the player has to outperform the other player because now they pretty much know what each player wants to do on both sides of the bolts are the individual play skill has to become involved. technology never stands still, much like the march of spot. microsoft have added something to the game. it

is subjective whether it improves it or not but one thing is certain, technology's drive to improve athlete performance will continue to develop. there is so much technology introduced now. our uniforms, have monitors, heart rate, things like that. a lot of stuff for player safety. technology going in helmets to track concussion, looking at brain activity. the game will be com pletely brain activity. the game will be completely different. uniforms and actual hardware that we wear is changing every year. i would expect a lot of technology to be integrated into what we wear on the field when we play. absolutely brutal that spot. it is oscar's season and every year we like to look at the visual effects behind some of the awards contenders. this week it is the epic

crime drama who was made robert de niro young again, the secrets of the irishman. you are not afraid of tough guys, are you?” irishman. you are not afraid of tough guys, are you? i did not think so. tough guys, are you? i did not think so. robert de niro starts at 28, then 36, 42, 47, 55, 62. marty said to me, be careful what you which involved. any kind of little cameras are in front of him. they are going to be on said with lighting and we're not going to go somewhere else. when we started developing this new of capturing performances, there was nothing available for us. the only way to capture performances

we re the only way to capture performances were through a market system so we had to find a way to find something else beside the markers. we did a test with robert de niro in new york which we recreated a scene from the goodfellas. there was now to witness cameras on the side. we found out right away that it acts better without any shadows but when you are on set you have shadows. generally your lead from the side or back. how do you neutralise the lighting without angering the director or the director of photography? maybe we flood the set with infrared light which the un i cannot see but the software can see. —— human eye. it was part of the director camera, so

not very many visual effects. wherever the director camera goes, the cameras ago so then we get all that information with us and we work through infrared light into the address. we got all that information and it created geometry out of that. if you naturally get rid of the markets, then you start seeing incredible movement on the face. things we did not see before. the geometry, micro— movements forming too much the background. the real performance. what you see on the screen are performance. what you see on the screen are 3d renders of their faces

with minimal involvement with performances. basically we made them younger but we did not change anything. we did it for the actors. an incredible amount of stuff that we get from it. even if we had a bunch all over the performance, it did not impact the director because there was nothing the director did that was stopped by the technology and also the performances were phenomenal. i am here to defend you, right? right. do you want to know if idid it right? right. do you want to know if i did it or not? i love that film. i wish it all the best when the oscars are announced next weekend. talking of which, next week we will be back

in la with an entire programme dedicated to technology and the movie industry. it will be a block buster. hope you canjoin us. and the meantime don't forget we leave on social media, twitter and facebook. thank you for watching and we will see you back in la. hello there. it was another windy day on friday. as we head on into the weekend, low pressure will always be nearby. so it will stay rather unsettled. mild for most, and they will be some rain at times but also some sunshine too. so here it is. low pressure to the north of the uk on saturday. this will bring some rain to northern areas. quite a few isobars on the chart, hence the windy weather. and this area of low

pressure, it will arrive saturday night into sunday. the very mild air will be pushed off into the near continent on saturday, and something a little less mild will move in. but it's still going to be pretty mild across the south. a blustery day for most of those weather fronts that i showed you, affecting scotland, northern ireland and northern england. we could see a little bit of rain across the south—east but that will clear away and then for many it will be sunshine and showers into the afternoon. most of those showers across western areas. the winds dig down from the north across scotland, blustery here, but also blustery across england and wales. wind is coming in from the south—west, so it will be much milder across the south and further north. turning chilly. a few wintry showers here. 10 or 11 degrees in the south, not quite as mild as it was on friday. as we head through saturday night, one or two showers around, wintry weather on the hills in scotland. a quiet spell before the next area of low pressure comes hurtling into bring up ranks of rain into northern ireland, england and wales. some of it will be mild and heavy through saturday night, turning mild

again in the south as the rain arrives, quite a chilly night to come across the north and north—east. here it is. a bit of a complicated picture through sunday morning. bas weather sliding north, tending to clear away from eastern england as the morning wears on, but it could be a damp start for northern and eastern england, northern ireland and central and southern scotland, as that rain bumps into the cold air across scotland we might see some snow over the mountains there. into the afternoon, it improves for many, sunny spells around, one or two showers across western areas. you will notice the mild air will be back, up to 14 degrees here, chillier in the north. as we head into monday, this area of low pressure, a deep low, will bring a swathe of severe gales to the north of the country, certainly to scotland. could see snow on the high ground. the windy weather clears away into tuesday and then we see a big area of high pressure building around the middle parts, but will settle things down, but it will be colder. a milder day on monday.

some rain around. mid week, high—pressure bills and it will settle down to brighter, with overnight frost and gradually milder by the end of the week.
