has asked the supreme court to suspend his 12—yearjail sentence for bribery. it comes just hours after he was due to hand himself into police. he has been holed up in the headquarters of a steelworkers union. stocks on wall street have fallen sharply as president trump threatens an additional $100 billion worth of tariffs on chinese goods, fuelling worries of a trade war. the dow closed down 575 points. doctors treating the former russian spy who was attacked with a military grade nerve agent in the uk say he's no longer in a critical condition. sergei skripal and his daughter yulia were found slumped on a park bench in salisbury, nearly five weeks ago. britain says russia is behind the poisonings, but moscow continues to deny any involvement calling the accusations "horrific and unsubsta ntiated". now on bbc news, it's time for click. this week, we are talking sg,

this week, we are talking 56, the latest tech. starring robot hands, robert feet and a robo worm. welcome to bournemouth on the south coast of the united kingdom, famous for sandy beaches, seaside amusements... and having the worst ag in the uk. it is very, very temperamental, i hate it. really, it is really not good. well, there is

some good news. 56, the next generation of the mobile network, is coming. but it is notjust about your phone. 56 promises to enable self driving cars, smart cities and the whole internet of things as every machine starts talking to every machine starts talking to every other machine. this week, the first stage of bidding to become a 5g first stage of bidding to become a sg operator in the uk ended with companies splashing out more than £1.73 companies splashing out more than £1.3 billion for the privilege. to date, no standards have been agreed, but we do have a rough idea of what 5g but we do have a rough idea of what 56 should look like. let's get you 5g 56 should look like. let's get you sg ready. five things you need to know about 56. one, yes, 56 will be much, much faster. hd movies can be downloaded in seconds rather than minutes with speeds ten to 100 times faster. two, unlike ag that

broadcast in all directions, 56 antennas will send concentrated teams directly to your device. three, 56 is all about superquick response times and that is crucial for things like self driving cars which will use the technology to communicate with each other at high speeds. for, it is a new wave. sg will use a part of the radio ‘s frequency spectrum that has never been used before, meaning it will broadcast on shorter millimetre waves. that means more data for all those devices. but there is a problem. these waves can't travel through buildings or even rain. five, the solution is new masks —— masks and lots of them. the good news is they only need be tiny. these mini masts will need to be much closer together and they will act like a relay team transmitting signals around buildings. sg projects are still being trialled

and as the kinks in the technology are still being worked out, we have been to see what is claimed to be the world ‘s first public 56 testbed. the trial taking place here in bristol at the millennium square aims to give the public an idea of what 56 could make possible. this communal virtual reality experience shows streaming of high bandwidth content on many devices all at once, all on one network was no time lag 01’ all on one network was no time lag or drop out. dancing in unison, we played a game involving chasing moving stars. these demos couldn't be in full 56 because current smart phones can't oblige, but every other element is there with these 56 new radios throughout the area transmitting signals. the team here anticipate sg transmitting signals. the team here anticipate 56 to be a network of networks, combining the best

elements of conductivity we have now with millimetre or extremely high frequency waves, plus up at —— potential to tap into wi—fi networks and wi—fi connections, particularly when we are on the move. imagine for insta nce when we are on the move. imagine for instance that you are having wi—fi network while you are having the sg 01’ network while you are having the sg or the ag network, you are in the train, nothing works, and in the tunnel, the network we are demonstrating and your connection automatically without you realising is going to switch from your faulty —— ag network to the sg is going to switch from your faulty —— ag network to the 56 network. is going to switch from your faulty -- ag network to the 5g network. we have talked a lot on this programme about the possibilities for smart homes, connected transport and of course the smart cities and sg homes, connected transport and of course the smart cities and 56 could provide the catalyst for more of them to actually come into play. this prototype aims to display one way that 56 could be used within a

smart city. what you can see on top of this cycle helmet is a 360 degrees camera, and the battery pack. the idea is someone cycling pack. the idea is someonecycling the city would be throughout the city would be co nsta ntly throughout the city would be constantly picking up pictures and they would be fed through a 56 network so if there was any problem, that could be found immediately and dealt with without delay. and if we can rely on that low latency, that is game changing. when it comes to robotic —— robotic surgery, a bit thick and could mean the difference between life and death. or it could between life and death. or it could be used to create realities are that seem almost impossible, like anyone being able to shoot a goal like messy via a 56 connected robot legs off course. using 56 technology, i am able to have a reaction. i can transmit touch. for the first time we can transmit engineering skills,

musical skills, football skills, medical skills and suddenly, we will build an internet which will allow us build an internet which will allow us to democratise labour the very same way as the internet has democratised knowledge and information. for most of us, though, we just want better connection, and the networks seem keen to manage our expectations beyond that. the average person on the street will see 56 as a way get them a much better smartphone experience, give them faster data connections, lower latency. but it is important to remember that we are right at the start of the sg journey and we need to look ahead of the next decade to look at what you applications beyond smart phones will start to appear as a technology but she was and becomes more widespread. south korea, the us, china seemed to be leading the way with commercial launch is expected later this year. but in the meantime, smart phone manufacturers will be working on bringing us the 5g will be working on bringing us the sg compatible devices that we need

for whenever the time comes. that was lara in bristol. here in bournemouth, sg that was lara in bristol. here in bournemouth, 56 on is somewhat underwhelming to say that —— ag is somewhat underwhelming to say the least. it took about the arrival of 5g. least. it took about the arrival of 56. i least. it took about the arrival of 5g. i say bring it on, bring it to bournemouth first. it might any fires for me. i can see it being useful for me in about ten years an eyecatcher with the rest of society. i still think about... is in 3—d? i am pleased with that. —— 3g. i still think about... is in 3—d? i am pleased with that. -- 3g. the local authority is looking to make bournemouth in the first place is globally to deploy sg bournemouth in the first place is globally to deploy 56 and become the first smart city, technically smart town in the uk. heading up the increment aish are not 56 is ruth spencer who took me on a tour to show me some of the new cabling and

potential antenna sites that will underpin what will be a radical new job. ag to 5g is going to be a massive change in infrastructure. in ag, you would have big masts, long—distance paths. ag, you would have big masts, long-distance paths. cover in a large area. 5g, particularly in urban areas, you need lots of small cells close together. that is a massive infrastructure challenge, isn't it, if you need lots and lots of masts to cover a city. i think what we are trying to do at the moment is understand how cost—effective it is to deploy this kind of level. it sounds like a massive ask. is it realistic? it is a big undertaking. other potential that macro will to —— sg a big undertaking. other potential that macro will to —— 56 will offer will be transformative. the problem is the sg will be transformative. the problem is the 56 signal is very fragile, easily blocked by trees and buildings and that means the team has had to produce really detailed surveys of where the antenna need to

bear. whenever you put a new building up, it interferes with the 5g building up, it interferes with the sg array of signals that you've got. so that's a problem. yes, it is a challenge that needs to be looked at. with a map and planning software that we have been developing, we need to start considering how do we update those tools and how do we update those tools and how do we update the maps that we are looking at in order to plan those networks. but it is the potential that may make the investment worth it. 56 will be the backbone of all those futuristic technologies that we have been long promised. the 5g is necessarily about getting better signal on your phone or faster data speeds on your phone. it's about machine to machine communication. machines in advanced manufacturing, robotic so it becomes much more about the opportunity sg robotic so it becomes much more about the opportunity 56 will bring around productivity as well as the ability to deliver services. for 5g

to work, serious investment value in this is needed, so could it be that some cities will be flush with transformative technology while other places will be left behind? i get the sense we might be about to see the beginnings of a new digital divide where some areas have 56 and some areas don't. for example, rural areas where there is a small population, so itjust might not be worth it. something they miss out. while 5g worth it. something they miss out. while 56 is likely to be rolled out in cities, there is still the opportunity for rural areas to really benefit from 56 in other areas, like farming, connecting autonomous tractors for example and he would need some 56 infrastructure to support that, but you would need something different in a city. it is about understanding what is needed for users in which locations and what is needed for infrastructure in which locations. we are talking

about autonomous vehicles being able to ta ke about autonomous vehicles being able to take you anywhere. if it turns out they need a 56 network and you roll into a city which doesn't have a five g network, what will that mean for your autonomous vehicle? will not be able to operate in the city? one of the areas that are looking at is where they will be deployed and what they are useful for, so for example, in the early stages, maybe you can connect to autonomous vehicles across motorways, covering long distances, with freight door that sort of thing, and then it will evolve. hello, and welcome to the week in tech. it was the week that the facebook scandal rumbled on. the beleaguered social network has said that the date of up to 87 million people may have been improperly shared, many more than previously disclosed. it also revealed that most of the users may have had their day to scrape from profiles using

now disabled malicious search techniques. a gun attack on you to's headquarters in california left three people wounded. reports say the female suspect was motivated by angen the female suspect was motivated by anger, that her belief youtube was filtering have videos and reducing the money she could make. researchers at mit have developed new technology that allows people to use speech recognition without actually speaking. it uses electrodes for signals produced when the wearer thinks about verbalising words, so now you canjust sounded. an advert for the smart phone featuring tom bailey has caused a splash with authorities in the uk. the add—in which the limp and was shown taking self is in a swimming pool has been banned at the advertising watchdog said if customers use the phone in a similar action, they would likely damage. in russia, the inaugural test flight of a delivery drove was more omg venue ps after it was destroyed shortly after ta keoff. ps after it was destroyed shortly after takeoff. the $20 , 000

ps after it was destroyed shortly after takeoff. the $20,000 drone smashed unceremoniously into a wall in front of onlookers. over the last few weeks we have been looking a lot at how you may be working in the future, on building sites, in factories and even in the doctor ‘s surgery. you know the story, robots, jobs, cars on the scrapheap, repeat. in the retail space, amazon is driving a lot of changes. automating the picking process is as critical as automating the delivery process. every year they hold the amazon robotics challenge and this time it was won bya challenge and this time it was won by a team from brisbane. we went to meet the brains behind the robots. 16 teams from around the globe went robot to robot injapan. the goal, to build a custom android that can

identify common objects, them up and sort them out in record time ticks thatis sort them out in record time ticks that is gripping the $80,000 gram prize with these guys come from the australian centre for robotic vision at the queensland university of technology. and when i got an invite for a private tour of their laboratory i expected a conservative welcome from studious scholars. ok. let's go and see. after you. how fitting that an award—winning robot should have its own robot butler. all of these robots require some degree of specialist knowledge. all of these robots require some degree of specialist knowledgem all of these robots require some degree of specialist knowledge. is a specialist is not there on the day it is hard to get the robot to operate. pepper, anyone can book are out and start running it. if you wa nt out and start running it. if you want to see it in action, select an item on my screen. let's try the marbles. hague, please fetch the marbles. hague, please fetch the

marbles. a robot is telling another robot how to be a robot. cartman has three axis of movement and works like a arcade court. it has two hands. a suction group and a pincer. he chooses which one to use depending on which item he needs to pick. there are many different ideas to be brainstormed and prototyped and engineered and finally this is what we came up with. this is the one that won. not very compact, is it? cartman sees what he is doing by a depth sensing camera which helps him visualise 3—d models of objects. you can see that the stock stick out further than the marbles. with that information be robot then decides what to pick and where. he is able to identify all products and add new ones as well. is discerning eye is critical. in the amazon case there

are so many new objects every day that they cannot have just a library of all possible objects ever. the vendor puts a new sticker on an object all the boxes changed shape and it becomes a new object and you need to train the system to understand that this is the new object. the team now looking beyond the warehouse walls. it is not about picking items from a shelf, but from a branch. meet harvey. the capsicum picking robot. we grow a lot of capsicums and we export a lot as well. we have a big agricultural industry here in australia and one of the things we want to prove is automating that technology and improving the performance and efficiency is. he has also so got two arms and a special camera to see what is in front of him. he knows when fruit is ripe and uses an electric saw to cut it from the stem. it also uses a

state—of—the—art deep learning system to detect the map peduncle. what you get is activations and we visualise this using a heat map. what that gives us is an area of interest where it chooses the peduncle. wanted spots the pepper, getting around the leaves can be fiddly business. this is a new camera system that comprises of nine different camera lenses at different depths give the impression of a human looking around leaves. it is powered by nine individual brass bree computers and is cheap. park is a proof of concept at the moment. the team yet to prove how commercially viable a robot like this is. that he could reduce crop waste by helping farmers to harvest more peak times. he can work eight

hours straight without a tea break. the other value with ian harvey is not just harvesting the the other value with ian harvey is notjust harvesting the fruit of being a full crop management system. what this allows it to do is to detect fruit, detect a grade of the fruit and also inform the grower watch is on his plant in real—time. this can then tell the grower where to send it. make contracts and sell this group for it is even harvested. thank you very much, pepper. it has been a lovely to. i think it is time for me to go. we should say farewell here. brilliant. that was nick and brisbane. and, what does this mean for us? will we all be out of work or will a new raft ofjobs be created? this or will a new raft ofjobs be created ? this is or will a new raft ofjobs be created? this is what our panel of

academic experts predict.|j created? this is what our panel of academic experts predict. i don't see anything to suggest that there will be mass unemployment over the coming decade. there is no reason to believe that the quantity ofjobs is going to be a problem in the future. what is a big problem, i believe, is that some workers will suffer from downgrading as they lose theirjobs. we need to find solutions for that. firstly, people will need to retrain. traditionally we have this idea that you go to university for maybe three years and in your mid— 205 you are sorted and you work some sort of the job for the rest of your life. i think we will be continually and retraining. we need to be

prepared for that. universities will have to play a role in training not ju5t have to play a role in training not just the young students but throughout your career as we grow older. we will be working for much longer. what does that mean for education and training? across sec is from schools to workplace training? are our system is preparing people for a workplace where there will be automation and there will be artificial intelligence systems and how can we improve ourselves as learners? these will be vital skills in the workplace of the future. so let's use ai workplace of the future. so let's use al to help us be smarter ourselves. i certainly think that is prefera ble ourselves. i certainly think that is preferable to worrying about whether artificial intelligence will replace a. who wants to be stuck in the same job for the rest of their life? that is something we should embrace, the chance to do new things. we need to

move away from a them that relies on stu d e nts move away from a them that relies on students memorising information. —— from a system. that is what we have computers to do effectively. what we need to move more towards is a curriculum that encourages things such as collaborative problem—solving. such as collaborative problem-solving. we need to realise that reskilling is not known to be a solution to everything. the best solution to everything. the best solution i know goes to wage insurance. that is being trialled in the us for workers who lose out to win pole competition. if we can show that yourjob was lost due to globalisation, the government will give you a surer and that you will not earn less than this amount if

you find another job. not earn less than this amount if you find anotherjob. we should apply that to robotics as well. you may say should ai pay tax if it is working and taking somebody else's job. i don't think the ai should be but i think we should perhaps put tax on data because this is what is being exploited. what i do not think people realise is that they are giving up huge amounts of data for free. and ownership of that data is going to lead to ownership of work. sometimes data is the new oil. who owns the oil rigs will have the power why. that does serve as an effective model for those companies against new entrants. maybe this is something we want to think about as a society, in our industrial policy. maybe we want to think about ways we can continue to support innovation

even when so much of the value in an industry is trapped in data sets owned by big tech companies. with him european research councils there is an extensive discussion about trying to push for what they call responsible innovation. encourage engineers and scientists to think more responsibly about the processes of automation, to engage with us users, notjust as of automation, to engage with us users, not just as consumers of automation, to engage with us users, notjust as consumers but of automation, to engage with us users, not just as consumers but as workers. a good future of work is one in which people can achieve work together. that is the four cars. don't forget we live on facebook and on twitter as bbc click. this may be the worst

place in the country for ag, but it is one of the best for this in chips and that is where we are going now. —— fish and chips. hello. thoughts on the weekend in just a second but first of all i think we should mark the fact that on friday here in the heart of london the temperatures reached in excess of 17 degrees alpheus, the warmest day of the year so far. not far behind in the sunshine stakes, this was south wales. the body had to have all the cloud and rain and initially it was there in northern ireland and then moved on to scotla nd ireland and then moved on to scotland and it was captured beautifully in the heart of sterling. the weekend, cloudy, damp and mild. there will be dry weather. this is how friday shaped. the

reason why we had the brightness down towards the south—east and the warmth was because the frontal system never actually made it down into the south—east and into the first part of saturday, the rain still drifting its weight slowly towards the northern half of scotla nd towards the northern half of scotland and then it comes back from the north sea down to a new area of cloud and rain towards the south—west. cloud means that the weekend will not start on a particularly cold now. that frontal system that i have drawn there is a straight line and will waive all over, particularly in the central and eastern parts of the british isles are a good part of the weekend. to the east there is some relatively mild air to be had. as i say, we really have the temperature up say, we really have the temperature up to 17 and we will not be far off that market we get a little bit of brightness, perhaps, across east anglia and the south—east. further west, close to weather front, perhaps, the rain can be quite heavy for a time perhaps, the rain can be quite heavy fora time and perhaps, the rain can be quite heavy for a time and as you see it drift very slowly further north it could

eventually lead a run on the day end up eventually lead a run on the day end up in northern ireland could reach the scottish borders and eventually clear from the south. a bit of brightness here and that is where it could hit 16 or 17 so some nice dry weather across the north of scotland. and from saturday an end to sunday, same weather front. a little wave on it there. a zone of cloud rather than a thin and of cloud. and, again, at its thickest it could produce rain. at this distance my muggy is on the fact that there could be cloud and rain across east anglia and the south—east. elsewhere, this one is that the must, lots of dry weather around and there may be sunshine that could even as far north as edinburgh, be boosting the temperatures to around 13 degrees. just a sneak peek at the start of next week when you thought it was this atlantic front coming in to dominate the weather in fact it is a low pressure of france which eventually turned cloud and rain in from the east and south—east across a good part of england and wales the

best of the dry weather at the moment. welcome to bbc news, broadcasting to viewers in north america on pbs and around the globe. i'm nkem ifejika. our top stories: brazil's former president lula is negotiating his surrender, his lawyers are asking the supreme court to suspend his prison order, hours after a police deadline. doctors say sergei skripal — the former russian spy poisoned with a nerve agent is making a rapid recovery. us stocks fall sharply after president trump threatens the us imposes sanctions on russian companies and individuals. facebook says it will verify the identity of people running popular pages as part of its efforts to stem fake news. police in new york charge martial arts fighter conor mcgregor with assault and criminal mischief
