this is bbc news. the headlines: american officials have described the start of talks in vienna — intended to revive the international deal on iran's nuclear programme — as a welcome step, and constructive. a state department spokesman said the discussions are expected to be difficult, and an early breakthrough is not anticipated. brazil has registered more than 4,000 coronavirus deaths in 2a hours — a new record for the country. the public health system has been largely overwhelmed by the surge in cases. president bolsonaro has been widely blamed for the crisis — he has consistently played down the severity of the virus. the jury in the trial of derek chauvin, accused of murdering george floyd, has been told the neck restraint he employed was against policy and training. prosecutors say mr chauvin made no attempt to calm mr floyd down before kneeling on his neck. he knelt on his knack for more than nine minutes. —— neck.

now on bbc news: click. need a new career? this is where the jobs need a new career? this is where thejobs are. need a new career? this is where the jobs are. and robots that build more robots. what could go wrong? welcome to click. it was exactly one year ago that i stood on this beach, looked into that camera and said some pretty improbable—sounding things. first of all, click had been on airfor 20 years. secondly, the world

was going into lockdown. and, thirdly, because of that, we didn't know whether we were going to be able to continue making the programme. and then, of course, the next week, wejust forgot to stop. and now, 12 months on, the vaccines are offering us a way out and that is thanks to science and technology. and also, i'm still pretty much in one piece as a human being, and that is thanks in part to the person who i am so glad canjoin me on the beach today. hiya! oh, thank you! i've tried my best. we've spent a lot of time on zoom! yes, we have. but not today. it's great to be here in real—life and isn't this absolutely beautiful? yeah. every bit of normality feels so special right now, but as we edge towards the lives we once knew, work could have changed forever. many businesses have closed, people have lostjobs and for some, this mayjust be a time to change career.

but some industries are thriving and hiring. home delivery outfits, streaming entertainment and video games. and marc cieslak has been spending some time with the uk games developers who are part of this growing industry. young or old, hardcore or casual, the pandemic has seen an explosion in the amount of people playing games. the size of the uk market has led to increased investment and growth for lots of video games development studios. the brains behind the football manager series, sports interactive, is based here in east london's 0lympic park. as a studio, we've been going forjust under 30 years, originally started in two kids�* bedrooms in shropshire. since then, we've grown very organically over the years to a team of 35, then to a team of 100, then to 150, and in the last year, we've grown to 200. so far, as a studio, we've sold 33 million games around the world, mainly

football management titles. this is sumo digital�*s studio in sheffield. they most recently launched sackboy�*s a big adventure for the ps5 and are working on a medieval multiplayer heist game hood, slated for release later this year. we make video games for all consoles and mobile. we have many studios in the uk, from newcastle in the north down to brighton in the south. in the last two years, of which the pandemic has formed 50% of that, we have grown. we've added anotherfive studios to sumo digital. the group's headcount has grown 36% in 2020, so it has been a year of growth.

these are both games companies producing blockbuster titles who have experienced recent expansion. during the pandemic, obviously, it has been really hard for everyone. we have been very lucky in that our revenue hasn't stopped, as it has for some companies. but making games is hard. and making games when you're distributed around the world is even harder. and we were determined to still release games last year, so we actually ended up going on a bit of hiring drive last year. we have accelerated our growth plans, so the growth we were expecting in the next three years we've done in one, and went up from 150 people to 200 in the last year. sports interactive�*s growth means the company is moving to new, bigger offices just around the corner from its existing base. games are already the most successful entertainment medium in the world and the pandemic has resulted in huge numbers turning to them as a means of entertainment or connection with friends and family. this has led to massive financial success. last year, the uk games market generated £7 billion, up nearly 30% on the year before. but is this growth sustainable post—pandemic? being realistic, i don't think that that growth rate is going to continue, but i also don't think it's

gonna taper off completely. i think a lot of people have discovered games in the last year that are going to carry on being gamers, being gamers forever. a short distance from the olympic park on brick lane, we find a company making different kinds of games. it's notjust the blockbuster studios that have been experiencing growth — the indie development sector is expanding, too. so we've been around for about three years now and we make games for teenage girls. these days, 84% of teenage girls play video games. it is actually more popular of a hobby than shopping. loveshark has developed a mobile title called mochi. follow the action on screen

to achieve a better score, as demonstrated by the game's developer rosa here. my own attempt to play is perhaps the strongest evidence i will ever need that a stint on strictly is not for me. during covid, gaming has seen a huge boom and that has meant that more and more investors want to invest in the space. we have been able to build more games, develop faster and also expand our team, so we have doubled the size of our team in the last year. so games companies big and small are crewing up as a result of market growth and investment. as the jobs market is left reeling from the effects of the covid—19 pandemic, could a career in video games beckon for many? but are people about to enter the world of work or those thinking about a change in career equipped with the skills necessary to work in video games? the unfortunate reality is that there is a skills gap in the uk, which is going to be difficult to fill — particularly in the areas of programming, but it is not

just programming, there are other roles as well. there are lots ofjobs that people could retrain to be looking to do. becoming a programmer is something that i would encourage anyone at school and any parent that's watching this as well to encourage their children to get into. a source of entertainment and employment — video games are a truly successful 21st—century combination of art, commerce and technology. now, a few years ago, we visited mit in boston, and one of the most memorable departments there was csail, the computer science and artificial intelligence labs, it is where they make all the weird robots. but now i worry the department might have put itself out of a job. you see, one researcher there has built a machine that can build more machines. lj rich has been finding out how it works. you're witnessing the miracle of birth. a fully—assembled drone freshly printed by machine. laser factory works by cutting out slices of acrylic, printing circuitry with liquid

silver and picking components up and sticking them down, all in the right order, at the right time and in the right place. thousands of people would come here to play video games in person, but of course, this year, it's all online. what was the thinking behind the festival this year? fix, the thinking behind the festival this year? a huge part of it is making _ festival this year? a huge part of it is making sure _ festival this year? a huge part of it is making sure things - festival this year? a huge part of it is making sure things are| of it is making sure things are accessible, all of the games we have picked are available to play online, the vast majority are available to play for free. some of the games you can play

london, and one of the main things is litter, hear, define, i imagine this could be fun to play with some children in the countryside, and you just get back to nature or even discover things in the urban environment, too. games and play can be a really interesting way of exploring some really serious issues, because they are low stakes and they allow you to explore different solutions and different solutions and different ways to look at things without too much weight, so you can pick it up, have a play, try things out, especially with role—playing games and you can think about some really large issues, like, how governments may deal with certain situations. and that is exactly what climate interactive has done, they sing you in an online simulation of the paris agreement. you make policy decisions and see how they play out. it’s policy decisions and see how they play out-— they play out. it's an

changed its name to volkswagen to highlight its electric car after the whole diesel emissions scandal. it has changed its graphics. the german carmaker admitted it was an april fools' dayjoke, in march, which it had posted early, the wrong month for aprilfalls. a few early, the wrong month for april falls. a few months ago we visited mit in boston, and a memorable moment there was the labs where they make the weird robots. but now i worry the department might have put itself out of a job. you see, one researcher there has built a machine that can build more machines. lj rich has been finding out how it works.

you're witnessing the miracle of birth. a fully—assembled drone freshly printed by machine. laser factory works by cutting out slices of acrylic, printing circuitry with liquid silver and picking components up and sticking them down, all in the right order, at the right time and in the right place. thousands of people would come here to play video games in person, but of course, this year, it's all online. what it essentially is is a unified design fabrication pipeline for creating functional devices and robots. so you can actually fly something off of the production line? exactly, so that was one of the main goals going into this project, that we wanted to be able to fabricate something that required no human intervention to actually get it off the ground. that's amazing. and this is the device. it attaches to a commercial laser cutter and transforms it from a 2d machine to a 3d

all—in—one assembler. the detail in a project like this is mind blowing. for example, in this toy drone, one of the sensors has become disconnected, just one, and now it doesn't work properly. itjust bumps into a wall. i'm going to try and fix it. there are so many steps involved in building electronics, so how do you programme a machine to do everything? one thing we had to solve was to get the process to work, we had to build these path—planning algorithms to make sure that the objects you are picking up and depositing do not collide with each other. so there is just a lot of moving parts that you have to combine in order to get it off the ground and working. the inspiration for this, like so many devices, comes from science fiction. in this case, it is the replicators from star trek, which can make everything

from tea — earl grey, hot — to more complex engineering components. these replicators that you see in star trek, where they have these really crazy machines that essentially are desktop machines and are used to create anything from teddy bears to drinks to food to spacesuits, so this idea of having a single compact desktop machine that can print anything you like, we think that is a very powerful idea. well, it is time for the moment of truth. oh, it sort of works. well, it's back to the soldering iron for me. and it's back to the mit lab for martin. he's hoping a future iteration of laser factory could eventually help augment other laser cutters, turning them one day

still a few wintry showers there across parts of scotland. but lighter winds, clear skies, a frost as well. temperatures in some cities down to around —2 or —3 celsius early on wednesday morning. so wednesday's looking something like this, lots of bright, sparkling sunshine first thing in the morning. but the clouds will build through the morning and into the afternoon. so actually the second half of the day is looking a little overcast for some of us. and in the north—west of the country, later on in the afternoon, and towards the evening, the clouds will thicken further and we are expecting some outbreaks of rain in places like belfast, glasgow, much of the western isles. and that's because a weather front is approaching, the winds turning direction, actually milder air is reaching us. and by very early on thursday morning you can see that generally across the country it is frost free — almost. now, that change is brought by area of low pressure which will be tracking into the north of the uk. you can see that slightly milder air brought in by these south—westerly winds.

so i think on thursday temperatures, at least for a while, will recover to double figures, onlyjust. perhaps 11 or 12 across parts of england and wales. but with that also comes a weather front and outbreaks of rain parts of the north—west of the uk. i think the best of the weather will be further south and also south—east. now, as we head into thursday night and friday, that weather front will move across, in fact, it's a cold front and behind it we once again open up the gates to a cold air stream from the arctic, which could bring wintry showers to northern areas of the uk. so, yes, temporarily it is going to turn just a little bit milder through thursday, friday, maybe saturday, but the second half of the weekend it is turning colder again.

and this is the device.
