a neighbour heard she had heard a loud argument. the news comes as jeremy hunt challenges mrjohnson to ta ke jeremy hunt challenges mrjohnson to take part in a television debate earlier than planned, before ballot papers are sent out to conservative members. the pair will take part in the first nation might hustings this afternoon in birmingham. the us and iran's relationship deteriorates, and the foreign office since one of its ministers to iran to call for a de—escalation of tensions in the region. president trump admits that earlier in this week, he came within minutes of launching air strikes. churches are discussing opening their doors after school to act as safe havens for young people who are at risk of becoming victims of knife crime. and celebrations for the history of caribbean emigration to the uk. generations come together on the uk. generations come together on the first ever windrush day. the prime minister has also announced new memorial. now on bbc news, it's time for click.

this week, we have a ringside seat for a tussle in toronto. tablets versus teachers in malawi. and it's a tech tko down at the gym. we all love a smart city. so around 18 months ago, when we heard that google offshoot sidewalk labs was to take over an area of toronto to build from scratch an entirely tech first neighbourhood, well, we hightailed it over there to find out more and excitement was in the air.

the streets will come alive with the vitality that we expect from the greatest urban environments, in a way that has never actually been seen before. ever since, it is fair to say that things have not gone entirely to plan. we have been back to toronto to get the latest on the project. toronto, canada's largest city. its waterfront is undergoing redevelopment. sidewalk labs, a subsidiary of alphabet, the sister company to tech giant google, has partnered with waterfront toronto, an agency set up by local government to manage the whole redevelopment. sidewalk originally had plans to build a so—called "smart city", on a 12 acre site in the rebuild area. 307 is sidewalk‘s test facility where ideas for this development are prototyped. what you are looking at right

here is a prototype for a new paving system for our streets. this one is a permeable paper, the water goes into the paver down into the ground itself. up here you see a solar panel, testing the integration of light into the pavers themselves. jesse is the development of urban designer sidewalk labs. he is showing off some of the tech it is testing before the company begins construction the quayside project. this one is testing a heating system embedded in the pavers and we then heat the paverjust enough so there is no ice that forms. this is the building raincoat, so it is a sunny day, it can adapt and provide more shade. if there is rain it can adapt to those conditions. sidewalk‘s plans involve robotic refuge collection and self—driving taxis, all assisted by a host of different sensors embedded in the neighbourhood. the whole endeavour will be driven by data, data about the weather, about the number of pedestrians and vehicles, and it is this use of data that has created rising concerns in locals. there are just a couple of problems

with this sci—fi sounding project. number one, it is way behind schedule, which is not unusual for redevelopment efforts. but number two, in a climate where the public is increasingly distrustful of big tech companies, do the people of toronto now even want this plan to go ahead? block sidewalk is a local campaign group that opposes sidewalk‘s plans. they are doing all this planning, bamboozle in people with stories about nice paving stones and... but the fundamental issues, is this for our benefit or alphabet's shareholders' benefit? they have never been answered, and i think i smell quite a large rat. trying to build a neighbourhood at the heart of toronto, on the waterfront, that is filled with sensors and technology that will be able to collect our data, our every move, is something that is very concerning to a lot of people.

how will our children be consenting to sharing their data, their behavioural data? these are all kind of questions that i think a lot of people have in mind. questions like these have increased tensions, and scrutiny of the whole project has intensified after several members of its advisory board resigned over privacy concerns. the project is also now facing a challenge in the courts. the canadian civil liberties association is suing three different levels of government, as well as waterfront toronto over plans for the tech driven development. michael, what is it that sidewalk is proposing that the ccla is unhappy with or opposes? what we are unhappy with is that a private company is self—regulating in an area that involves people's constitutional rights, their privacy, and their dignity. what the government in canada and ontario and toronto has done,

has said, "sidewalk labs, you figure out how to act "in the public interest. "you self regulate the way in which you are going to be "collecting and storing data. and we, those of us who live in toronto, or walk anywhere near or through this part of the waterfront, we are the lab rats. and number one, we never signed up for this, number two, there is nojurisdiction for waterfront toronto to do this, and numberthree, there is no protection whatsoever by law of the data that is being collected and manipulated and stored and used in whatever form it is going to be used. privacy and data, there are some huge concerns around privacy and especially data, about what happens to it, who will manage it. governance, who has oversight of the data. this project is fundamentally about protecting everyone‘s privacy, it is built on the established laws we have in canada.

it is not us that is planning to manage or make money off the data in this neighbourhood, it's actually proposed that it is an independent nonprofit public sector entity, we have altered in urban data trust, that will take response ability for managing and using the collection of data. sidewalk labs has just submitted its 1,000—page long master plan document that outlines what has in store for the quayside project in more detail. waterfront toronto says it will open it up for public discussion. i think you have a perfect storm, timing, players, actors and a pressure point on projects that could be a lighthouse of how you solve these issues if we get it right. if we get it wrong, then that would not be good. as more people become aware of the kind of data that is captured by big tech outfits, and how it is used, concerns around privacy mean decisions made in toronto could end up having ramifications for future smart city

projects around the world. that was mark. big tech companies offering services for free written by data. it is a familiar theme from toronto to timbuktu. originating in silicon valley, for some this type of business transaction has come to define the age we live in, and its consequences, good and bad, are onlyjust beginning to shake down. we have been looking at some of the most influential thinking in what is being described as" surveillance capitalism". we freely give out our personal data every day through the apps on our phone, conversations with smart home assistance or other so—called smart devices like toothbrushes and vacuum cleaners. it seems like an inevitable and perhaps cheap price to pay for living in a digitally connected world, giving us access to free services, like google‘s surgeon

match, and social media sites like facebook. but the data we are giving away for free about our everyday lives is very valuable, and it is exploitation — if exploitation is the basis of a new economic paradigms which one author calls surveillance capitalism. she presented her book in cambridge, also known as the uk's silicon valley. what surveillance capitalism does, is it claims private human experience, private human experience is unilaterally claimed to be brought into the marketplace, where it is translated into behavioural data. this behavioural data is combined with machine learning and artificial intelligence to create predictions of what people are going to do with their day, and what they might live.

professor zuboff details how this capability to make money from behavioural data was first discovered by google when the company was struggling in the wake of the .com crash at the turn of the millennium. to boost ad revenue, google mined its own exclusive data logs for the digital exhaust of people's online search behaviour. google worked out that this extraneous data was valuable, and with the ability to process large amounts of data came the ability to discern transient people's behaviour. this led to the development of highly tailored online advertising. everyone is familiar with this. you go online and you search for tennis shoes, and then the next day, you have ads for tennis shoes all of your pages. those advertisers are buying google‘s predictions about what we're going to do in the future. professor zuboff says these predictions have opened up a world where companies are even able to experiment with modifying human behaviour without our knowledge. in 2016, google‘s spinoff niantic

created the wildly successful augmented reality game, pokemon go, with people running around collect different pokemon. while it seemed benign on the surface, professor zuboff says it was designed as an experiment to see how people could be herded towards commercial targets and collect data from its users. pokemon go figured out how to direct us, out of our awareness, exactly to those places where pokemon go would get paid for our footfall. so it was an experimental vibratory on a giant scale, for the collaboratory on a giant scale for the kind of surveillance capitalism that learns to intervene on our behaviour, to direct it to the places that make the most money for surveillance capitalists and their customers. the most predictive behaviour comes from actually intervening in people's behaviour, intervening in your real life, intervening in the state of play. and subtly always designed to be

outside of your awareness. subtly shaping your experience. professor zuboff is asking us to consider the subtle implications of surveillance capitalism on our lives, comparing it with the impact of industrial capitalism. industrial capitalism may have left a mark on our natural environment, but perhaps we need to consider how, left unchecked, surveillance capitalism could impact on oui’ human nature. hello, and welcome to the week in tech. it was the week that facebook announced its new crypto currency called libra. this will allow smartphone payments across the world, and will be governed by companies including mastercard, visa, uber and spotify. some lawmakers have already raised concerns. google released a new tool to let youtube users test out different looks.

the feature called ar beauty try—on follows l'o real‘s recent partnership with amazon. and the founder of huawei said international sales of handsets some sunk 40% in the last month. the firm plans to slash production by $40 billion as fall—out from its us blacklist continues. samsung has advised customers to scan for viruses every few weeks to prevent software attacks. it has shared and now deleted an extensive video which might have put some off owning a smart tv at all. the first tesla pickup in the world, called the truckla, is not made by elon musk. a us engineer modified eight has modified the model three adding extra tech so she could weld on the road. don't worry, she unplugged the battery before surgery so the car felt nothing. finally mit scientist are teaching a robot how to feel an object by looking at it.

researchers say it will help the robot better when lifting things, like the handle of a mug. mine is a tea with two sugars, please. these days, fitness gadgets are about so much more than just tracking our activity. yes, of course, they want to make us exercise more, but they also aim to help us get injured less, and sometimes, even have a spot of fun as well. some of the latest gadgets certainly don't pull any punches. a set of connected boxing gloves. now, the sensors are embedded here, there is one in each hand so they can track how many punches you make and also the force of those punches. there is eight rounds. fight cab hopes to get you fighting fit by running you through a variety of workouts in the art.

the accelerometer—based sensors track your moves in real—time, recognising the difference between the warmup exercises and when you're pulling a punch. probably a good job this was a one— way match, as my lack of skill was pointed out by a professional boxer who happened to be to hand. ok, this is how you do it. although the wraps are the pivotal part of the kit, there are options for an entire set up with punch bag as well. how good at teaching boxing do you think this is for someone who's never boxed before? you start off by kind of doing it at the lower level because obviously it has levels, so start off at the lower level until that becomes comfortable, just like anything else. it will take time and dedication, but it's easily accessible to learn, as long as you take the time.

or maybe you prefer a simpler spot of weightlifting. this is a connected kettle bell and it has six different weights built into one device. you can change them byjust pressing a button. jack'sjocks uses a rotated weight stacking system. it locks in the number of weights needed to create your chosen weight, ranging from 5.5 to 19 kg. one charge of the device will last you up to 14 days. it synchronises to a mobile phone app where you can keep track of all the sets and reps that you've done as well as notice how much rest you've taken, and then you can keep on competing against yourself. meanwhile, away from the blood, sweat and tears of this gym, i've been looking at something a little more scientific as well. here at the university of brighton sports science physiology lab, there is all sorts of kit, and this rather intimidating—looking treadmill could be used to help analyse my gait, but instead of doing

that, we're going to head outside with these, which are the gait sensors. inside them, there is a gyroscope, and accelerometer, even a barometer but it's not about the hardware, it's the data that they are actually collecting which is important, and how that can be analysed to help me move better. and the new algorithms doing that are being used here for a collaboration called the sub two project to try and help elite runners break the 2—hour marathon mark. let's go. it seems i wasn't quite as wonky as i thought i was. when we look at you, you are fit and a good runner. not elite for sure, but not at specific risk to anything that we would do is fine tune. my colleague says i run like an elephant. do not run like an elephant? can i tell her i do not? visually it is the case, but i'm sure it is not the case. visually, oh dear. but the analytics, that's

the new bit here, not the hardware, do provide a clear report of your running. contact time, strike and asymmetry other focus factors, allowing professional level tracking consumers although the current price tag of 1,500 quid, i can't imagine them hitting the mainstream just yet. and while much of this tech mayjust seem overengineered and overpriced, maybe it's just early days for a fully connected workout experience that can really pack a punch. that was lara. now, it was an outrageous amount of money to give away for a competition, a $10 million prize, but some would say it's a small price to pay because the challenge was to find the best way to teach children remotely. the global learning x

prize, at it was known, was the brainchild of elon musk, aimed at developing a way to teach children maths and literacy in their own language that would deliver results as good as it would have been if they had the chance to go to class. the results have been impressive. last months in los angeles, two winners were announced, picking up $5 million each from elon himself. dan has been back to africa to talk to one of them about what they achieved and what might be next. cock crows the walk to school and back to where it all began. it was here in this village where, seven years ago, 1 billion handed out its first devices, before any of these children were born. some of them are still in use. andrew's charity is now working with partners in south africa, uganda, the uk, tanzania, as well as across malawi, but to its founder, this place is special,

as is winning the xprize. on a personal level, we just felt enormous gratitude. we've built on the expertise of so many people from around the world. obviously $5 million is very useful. it's really given us this opportunity to show that we have a quality product that can achieve this recognition from xprize. in tanzania, tablets were given out to 4,000 school—age children in 150 villages, most of whom scored zero when tested in maths and literacy at the start of the trial. 18 months on, and the results were stark. in many cases, better than would have been expected if they'd gone to school. and interestingly, with little difference in results between boys and girls. i think it's the biggest

educational learning trial anywhere in the world. we saw children making very significant gains in letter recognition, in reading words, in maths, recognising numbers, number discriminations. what this shows to us is that there is a solution to the global learning crisis. those positive results are reflected here in these 30—minute community sessions held at this village house. i have a daughter, and in the past, she was not doing well in mathematics, but when the gadgets came, she is doing good in school. schools in malawi, you will get one classroom with over 150 children. i know one school where there is 200, 250 children in one classroom. if you put in place, for example, what we're doing here, we are using the tablets, it will actually ease

the tension in class. can you imagine how many hours it takes to mark 250...? have a lesson for ten minutes and four hours for marking. there is a low—cost tablet building on what they've learned so far. these tablets often can be damaged by the usb plug, if someone doesn't know you got to put them in one way round, they can force in it can break. so we use a magnetic connector rather than usb, and it can be charged from solar. this adapts to the child. the software now has a chaos start—up mode, where it can assess the abilities of any child who picks it up in the background and build

a learning plan on the fly. andrew is keen to work with education officials and experts on the ground, allowing them to tailor the curriculum to each community. you say you are keen to work with partners. if microsoft came with a large amount of cash, would you welcome that? we believe that the child, particularly at primary school, needs to be in a sanctuary where they are not being observed and data is being extracted about them. all of us know that big tech companies are gathering data on all of us now. google probably knows where we are sitting now in the middle of malawi, and that information is monetised. i am fearful, i think we must protect children from being seen as a product in any way. one hours‘ drive north of lilongwe, and the potential of the software becomes clear.

this refugee camp is home to almost 40,000 bleeding wall of famine. here, one billion‘s partner, vso, is delivering hour—long classes. this is integrity church in the heart of the refugee camp. 50 or so children are here. tablets have been in for about a month. it's a little too early to assess the progress but the interest, you just have to look at the faces. the xprize has shown this open source software works and is one of the best of delivering these results. given the right funding, it seems hard to imagine why tablet schooling won't become more widely adopted. that was dan in east africa, what a fabulous story that was. that's it for this week. next week, we have a special programme on the subject of sustainable tech. i can't wait for that.

in the meantime, you can join us on social media on youtube, instagram, facebook and twitter at @bbcclick. here is the address. thanks for watching, and we will see you soon. hello, nicely timed for the start of the weekend. many of us have started the weekend. many of us have started the day like this. a view from cumbria earlier, and skies will stay like this throughout. slight chance of an isolated shower, the vast majority will stay dry. going to feel a bit warmer as well. so this is how the big picture is looking. low pressure eventually will come in into monday, but for now, high pressure is in control,

which is why we are expecting a fine saturday across the bulk of the uk. a bit of cloud across eastern parts of england this afternoon, which may produce an isolated shower. greater chance of catching the odd shower in northern scotland. and where it has been cloudy so far in northern ireland, sunny spells developing. around 18 to 21 celsius, 22 in cardiff and london. very high pollen levels in england and wales, though. this evening, barbecue in good shape, still a good chance of a shower of a northern scotland. just hints there will be some outbreaks have rain getting closer to the far south—west of england later in the night. not quite as chilly as it was last night. back to the big picture, looking at part two of the weekend. this area of low pressure getting closer and throwing this weather front towards the south—west of the uk, high pressure still in control elsewhere, but now, after a fine start, there will be increasing cloud across the uk, the breeze starting to pick up. maybe one or two showers, but the main area from that weather front we saw, just edging across more of

south—west england and into northern ireland, some of it starting to turn heavy and thundery in places. perhaps feeling a bit warmer, a touch cooler north sea coast, but more humid areas of south—east england. met office warnings for thunderstorms in parts of england and into scotland, northern ireland sing some rain, too. big variety of rain totals possible here, but certainly in have your burst, some of us could see a lot of rain. in a fairly short space of time as well, so the potential for some flooding and distrusting going into monday. all pushing northwards to give a wet monday for scotland. may be up to 100 millimetres, especially at higher ground, so the potential for disruption. a stormy start to the week, turning hotter, 31 celsius possible in the hotspots. not everybody that hot.

a this is bbc news. the headlines. it emerged that police were called to the home it emerged that police were called to the home of it emerged that police were called to the home of conservative leadership candidate boris johnson and his partner in the early hours of friday morning after a neighbour said she heard a loud argument. mrjohnson and jeremy hunt will take pa rt mrjohnson and jeremy hunt will take part in the first nationwide hustings event this afternoon in birmingham. mr hunt has called on his rival to agree to an earlier tv debate before ballot papers are sent out. i think we should be doing debate early. and often. you know, if the party wa nts early. and often. you know, if the party wants him to go out to battle against nigel farage, jeremy corbyn and 27 eu countries, then, surely, it's not such a big deal to go out against a friendly foreign secretary. as us and iranian dismantle iran
