voice-over: this is bbc news. we'll have the headlines and all the main news stories for you at the top of the hour, straight after this programme. this week — lara's checking out some fast food, sort of. i've just been told to stand back as things might get messy. i don't know how messy. the laundry making fast fashion greener.

and... oh, no! er, yeah, i think that's fast enough, thank you. pizza baking, burger flipping, salad tossing. over the years, we've seen food robots chop, fry and saute their way across the kitchen, saving us from one job at a time. i'm such a lazy chef. i love eating the food but i want to make making it as quick as possible. see, i don't mind cooking, as long as you don't mind eating the same stuff every day. well, i think there's a solution for both of our problems. right! over the years, we've seen more and more things become automated in the kitchen with various gadgets but now, the robotic kitchen may be upon us. this is the first—to—market robokitchen from moley robotics.

it's a fully reliable product which you can put, actually, at your home or restaurant, everywhere, and it's safe. it's time for lunch. what are you making me? today, we actually want to make omelette. choose the recipe. its arm sets the temperature, grasps items and moves with military precision to deliver ingredients. next operation is pour the egg. and it knows how much to measure? yes! look, it's got the egg in the ladle! yeah. and it's just trying to get any extra bits off so it doesn't drip. got to keep the kitchen clean, otherwise a human�*s got to do that cleaning. yes. pre—training with recipe data and sensors teaches the arm exact amounts and actions. and now, it's taking the next implement. how is it going to mix? in a slightly robotic way but it's doing the job! of course, you don't have to stand by and watch but for the first time, at least, it's pretty

mesmerising. it's off to get the cheese! ah, it dropped a bit. still a bit stuck to the tongs. it's going to shake that off. and then the tongs back there — tidier than any human would ever be. also, it's designed for constantly cooking, so it can cook without stopping in the hotel or in senior house or in restaurant. i wants to serve for ten people at two o'clock, for example, and it can start cooking to be able to serve ten or 15 people at two o'clock. a human does still need to do the dishes, though. there we go — so far, so good. and now, to try it. lovely! and the big difference between this and my own is this should turn out the same every time! so far, ten chefs have contributed to over 50 recipes to the moley database, ranging from stir—fries to curries, and more will be added when it becomes available in september. but there is still

manual labour involved. a lot of chopped—up vegetables here, which looks like a human has done most of the work already. yes, but these vegetables and this container could be delivered from a delivery service as a pack for this particular recipe. ok, so you could even avoid the chopping. dishes like this sweet potato soup could be personalised and, in future, you'll be able to input your own recipes. i don't eat garlic or onion, so i've asked for it to be taken out. though it does take the robot several days to get the new recipes right. like anything, you know, you usually need time to perfect anything. that's right. practice makes perfect, even for robots. absolutely. now for the liquid. that's stock, spiced coconut milk and some seasoning. ah, time for salt and pepper. laughs. that looks like such a clumsy stir!

it is impressive, but costing a whopping 50,000 quid, who's going to shell out for this spectacle? first of all, it's a lot of place when the chef doesn't want to work — for example, night shift, because nobody wants to sit down during the whole night and wait the order. you know? or if he wants to have a nice dish in the middle of nowhere and, for example, a chef doesn't want to work there, he wants to work in the centre of london, so that could be also the good options. i can imagine it being used in the commercial space but i do struggle to imagine many people actually having it in their home. the strategy of the company is continue working on the machine and continue to make it more and more affordable so, one day, for sure, as we promised before, it will cost much less — maybe 25, maybe 30k, so that's our goal. that's still quite a jump from a standard kitchen and it will sometimes need a wipe down. i've just been told to stand back as things might get messy. don't know how messy.

i normally make more than that, to be fair. for me, it's been totally effortless, but the real proof is not in the pudding, but in this soup. mmm! delicious! oh, it's got a bit of a kick to it. mmm, yeah, it's really good. very well blended by the robot and the blender. yeah, and the chef who create this recipe. and the software engineer that trained the robot what to do. there's more people involved in the making of this soup than i'd have thought. good, though. now, then, the race is on — not on the race track, but in our city centres. see, lots of companies are vying to lead the way in remote—controlled cars — full—sized ones, this is — with tests being carried out in the uk, estonia, the usa and germany, where alasdair keane has been behind the wheel.

this car might look like it's moving on its own, but the secret behind it is a team of drivers based in an office on the other side of berlin. the idea behind vay is that in a city, you won't need to own a car — simply order one to be delivered to you whenever you need it. with vay app, then, the car is being remotely driven by the teledriver to the customer, so the customer doesn't need to search for the car. just get into the car on the driver's seat, drive themselves to the destination and, at the destination, theyjust get out without the need to search for parking lot, etc. theyjust get out because the teledriver can then take over control until it drives the vehicle to the next customers. that took us about 30 minutes to get here.

this is a telestation, where they drive the cars as they move all over the city of berlin. and in a television first, they're going to let me have a shot. alina is one of the drivers. she's moving a car around the streets of berlin, controlled from here. as i prepare to take over the wheel, i can't help wondering if it's easy to forget you're in control of a car. speaks in german. it looks just like a normal car. the steering wheel has all the buttons that

i recognise but, of course, there's this big red button. exactly. what does it do? that's an additional safety measure which vay implemented in case something happens with the session, then the teledriver is trained to react to that by pressing the brake very hard and at the same time, the emergency button, which basically will also bring the vehicle to a safe stop. so, that's me now in drive. you have full control. 0k. foot off the brake. yeah. and we're starting to move forward. there we are. ifeel like i'm getting very close to these cones. yeah. 0h! it's very strange, the spatial awareness of where the cones are. yeah, it's something that you have to get used to. yeah. perhaps my driving reputation came before me but while i was behind the wheel, there was a safety driver in case things didn't go to plan. so, chris in the car is telling me to take my time. yeah.

at this point, ifeel like i'm speeding around the track but the car is going less than iokm/h. just as i'm getting confident... oh, no! i think i have a lot more training to do before i get let loose on the roads. drivers here go through hours of training, including theory and practical. controlling these cars relies on 4g and a signal between the car and the driver. we all, of course, have been there where we've not been able to get a signal for whatever we're doing. what happens if one of these cars loses a signal? it's a very good question. what we have built is like that, as you know from your

private experience, that some network providers in this corner have better quality than the others, so what we're doing, we have redundancies, meaning we're not only relying on one network carrier, we have, like, four multiple carriers, so if one falls, we still have three and so on. and in the unlikely scenario that all drops, the vehicle detects this in real time and comes to a safe stop. and then, depending whether they recover, we can resume operation. in hamburg in the north of germany, they are the first company in the eu to have permission to run this tech on the roads with nobody in the car. you can imagine seeing a vehicle on public streets and there's no—one inside. people, like, their reactions vary from disbelief to enthusiasm and excitement, and what we have learned is that they actually trust this technology when they understand there's actually a human that controls this vehicle and not the computer. and i think this is, like, very important because it also shows the opportunity and, like, paving the way

towards an autonomous future, which we believe in. there are still hurdles to overcome — not least building trust in this tech. but as connectivity gets better, we could be seeing more remote—controlled cars on our roads in no time. it's time for a look at this week's tech news. x formally known as twitter is facing a bill from local authorities in san francisco after an unauthorised x was placed on the roof of the company's headquarters. authorities said the company did not have permission to put up a sign and will be charged for the cost of its installation and its removal. the scottish island of 0rkney has become the first place in the uk to have mail delivered by drones. thejoint operation by royal mail and

turkey. but what's been barely reported is that google was operating an earthquake early warning system, which it claims had sent out millions of alerts to people before the quake hit. however, a bbc investigation failed to find evidence that this warning was actually received by most turkish people in the earthquake zone. anna foster in turkey and james clayton in san francisco have more. james: it was one of the most deadly earthquakes in modern times. february's quake happened in the middle of the night. many people died where they were sleeping, in their beds. 50,000 people were killed. however, there was an earthquake warning system run by google in turkey, and the company claims millions of people got a warning before this earthquake. it works on any android phone — that's about 80% of all of the phones in turkey — and this is google�*s explainer on how it works.

android phones have these tiny accelerometers built into them which can sense earthquakes. people will now be able to have their phones become part of this network of mini seismometers looking for earthquakes around the world. we call this the... when the phone detects an earthquake, it sends a message back to google�*s servers. when enough phones do this, google can pinpoint the epicentre and send out an earthquake warning. and so you'll hear it go... phone chimes it looks like this, and it says, . "drop, cover and hold. " so it's pretty loud. it's pretty loud. this is micah berman, the product manager for the system at google. if it was on "do not disturb," it would override that? exactly the same behaviour that you just heard, no matter what state your phone is in. you should get that warning? yes. the further you are from the earthquake, the more notice the system can give you, up to around a minute — enough time to try and find a safer location. so our system did activate

for both of the major events in turkey, as well as for a number of aftershocks. here's my colleague anna foster, who'd been reporting on the ground from the earthquake zone. i was really puzzled by that claim, because i was here on the ground in turkey in the hours and the days and the weeks after the earthquake. and nobody had ever mentioned in any interview with me receiving an alert before the earthquake. so we decided to go to three cities that had been impacted — adana, 0smaniye and iskenderun. i simply asked people whether they'd received an alert. everyone you're about to hear from has an android phone. so when the earthquake happened, the first one that happened in the night, did you get this alert on your phone at the time of the earthquake? no. and what about... ? so it looks like that and it makes a sound. phone chimes no. no?

no. no, no, no. no? no. we spoke to dozens of people on the streets. most people hadn't even heard of google�*s system. no, no. no? funda lost 25 members of herfamily, including her sister and nephews. so you didn't receive any alert, nothing on your phone? in all three cities, despite our attempts, we didn't find one person, not one, who got a warning for the first earthquake. so you didn't receive any alert, nothing on your phone? in all three cities, despite our attempts, we didn't find one person, not one, who got a warning for the first earthquake. i put our findings to google. how sure are you that, firstly, it did fire and secondly that it actually got to people

during this earthquake? i'm as sure as we can be that the system activated and that we did send alerts. it's possible, you know, that given all of the... ..like, the massive impact of the first event that this just quietly happened in the background while users were really paying attention to other things. at the end of the day, i think that's probably the most likely explanation, that users were focused on something else and might not even have noticed if they got the alert. have you spoken to anyone who got it? i have not, no, though i don't speak turkish and, you know, i'm not in turkey! so... i would love to. has google spoken to anyone? i don't know. harold tobin is a professor of earth sciences and director of the pacific north—west seismic network. these systems are extremely new, right? they're at the cutting edge of what's possible. i feel that if you are delivering an essential sort of...life safety, public safety piece of information, then you have a responsibility to be transparent about how it works and how well it works.

we can't be sure that no—one got this alert, but we can be sure that many people didn't. there was no blanket warning — a warning that could have saved lives. now, we know that fast fashion isn't great for the planet, yet many stores still sell trendy cheap clothes that are here today and gone tomorrow. but there are ways to make this trillion—dollar clothing industry more sustainable, as francesca hashemi has been finding out. millions of tonnes of clothes are sent to landfill every year, making the industry a major contributor of greenhouse gases and a massive consumer of a finite resource — water. fashion is the second most polluting industry after aviation and shipping. it accounts for 10% of global carbon emissions, and it's very water intensive. from manufacturing textiles

for cotton t—shirts to washing or dry—cleaning clothes, the industry relies heavily on h20. but some people are trying to change that. here at acs, we also use water, we're large laundry. we believe that, in the next 12 months, we will get to a stage where we won't take any water from the mains. this fashion hub rents, resells repairs and sanitises pre—loved clothes from the high street or luxury brands. but how sustainable is it? even though we might be working with some of these fast—fashion brands, we're wanting them to help change their consumer mindset, so in being able to rent or get second—hand fashion, rather than this kind of model ofjust consuming constantly. so working with these brands, we are helping them to increase their sustainability credentials, and we're stopping garments from ending up in landfill.

the way in which we handle the clothes on site and how we are carbon neutral, how we have gone through a process to minimise our co2 emissions on ourjourney to net zero, on our reduction of water, we know that how we handle them here is a much more sustainable way than what we all do in our own homes. talking of water, the entire operation once used about 20,000 litres of the stuff every day. about 50%, that's 10,000 or 11,000 litres, that was used in laundry. but they've managed to halve this by using something scotland has plenty of. acs now harvests rainwater from the roof, then recycles it to use for cleaning and preparing clothes for customers. what we have is, there's three pipes. the first pipe is actually the reused water, so this is the water from the laundry, and what it's done is, at the end of one of the final cycles, it's actually pumped out, and you can see along the pipe, and pumped into this tank. the computer inside the laundry knows when the next cycle

starts. it activates the pump that pumps the water out the tank, brings it up and brings it in at that inlet there. the second pipe that you see is actually the reused water from the coolant system. there's a tank in the floor above that's a hot tank, and that water is actually pumped in, activated by the computer in the laundry machine. that's actually hot water in there, and what it does is, it means that we don't have to heat it. and then the next one is for cold washes, and that water is the rainwater harvesting, which is actually, again, stored in a tank upstairs. so all the water collected for use on the laundry, it's not always clean if you're reusing it. how do you deal with that? you can see the waste pipe there, and the waste pipe goes through this very large filter, and it takes all the microplastics out. and the waste water then goes into the normal drainage system, the mains, and then what it's done is process the way that normal water

would be processed. the team partnered with the university of west of scotland to create a digital twin of their water consumption, and some of their findings are pretty interesting. so at the moment, acs utilises 5.5% of the roof area, which is about 1,000 litres of water per day. if it utilised the whole of the roof area, it would be able to collect around 18,000 litres per day. this would almost be sufficient not to utilise anything from external sources. the entire operation being self—sufficient in terms of their water consumption is aspirational and, of course, variable. but it's also a great example of what one clothing hub is doing to increase their sustainability credentials. but in this fast—moving fashion economy, what more could the industry do?

in terms of technology, we need a lot more data in the fashion industry. currently, the majority of fashion brands will only publish tier—one suppliers on their website, so the people who manufacture and make the clothes. when it comes to tier two, which is things like the making of the fabric, and then tier three, which is your raw materials, the majority of brands don't know where that's coming from. and i think, moving forward, that's the type of data we're going to need to be capturing in order to avoid greenwashing. that's all we've got time for. thanks for watching. we'll be back next week. see you. hello there.

friday brought us a line of slow—moving thunderstorms across eastern england, and they brought some very heavy rain. this was suffolk. further south, in essex, they saw 9mm of rain fall in just the space of one hour. so the rain was really quite intense. talking about rain, we've got more of that to come on saturday, thanks to this area of low pressure which has been named by the met office as storm antoni. now, antoni will have a number of hazards. the first — heavy, persistent rain for northern ireland. 20—a0mm here, maybe more than that over the high ground in the mournes. there could be enough to bring some flooding issues here, but as the rain extends into england and wales, the winds really pick up. for wales and south west england, we're talking about gusts reaching 50—65mph in places. could be strong enough to bring down 1—2 trees, so there is the risk of seeing some transport disruption. the wet and windy weather will continue to extend

its way eastwards. it will be brighter for scotland, a mixture of sunshine and a few showers here, and brighter through the afternoon for northern ireland as well, with the winds slowly calming down. for some, it will be really quite a cold day for august, with temperatures potentially just around 111—15 celsius for some. now, as we go through saturday night, the winds will continue to calm down, the rain tending to become confined to eastern areas of england, the weather drier across western portions of the uk. temperatures overnight, saturday night, well, ranging from around 7—12 celsius in our larger towns and cities. sunday is the better of the two days of the weekend. it's a day of sunshine and showers, the greatest chance of seeing showers across scotland and eastern areas of england, where some of them will turn heavy and thundery. probably largely dry across wales and south west england, but wherever you are, our temperatures continue to be a little bit below average for the time of year. now, monday looks like being a cheerier day for many of us. not completely rain—free, mind you. after a sunny start in northern ireland, we could see some rain arriving late in the day, and there will be some showers working into north—west scotland. england and wales largely dry with some sunny spells. our temperatures still roundabout the high teens to low 20s. so not a bad kind of day overall, but then, tuesday not

a good day. we've got a weak area of low pressure crossing the country, and that means, yes, more rain, although things will probably brighten up in the west as we go through the day. so northern ireland cheering up through the afternoon with sunshine and may be an odd shower. temperatures still high teens to low 20s, so still not particularly warm for august. but we will see changes in the weather pattern beyond that because later in the week we'll see our first area of high pressure across the uk for some seven weeks, and that's going to be dragging in some warmer air. now, with that, we should see temperatures climb at least into the mid—20s, maybe the high 20s in the warmest spots in the best of the day's sunshine on thursday. now, the reason we get a big change in the weather pattern is down to the jet stream. this was quite typical injuly — very large waves, so we had a big ridge in the mid—atlantic, big troughs near the uk that kept developing low pressures that fired across the uk. that big—scale pattern tends not to move. the jet stream blocked, it was very unsettled. whereas looking at the weather later in the week, the jet

stream taking these smaller meanders, and this kind of pattern does tend to move through. so there will still be ridges where we get high pressure, there will still be some troughs around, where we get low pressure, but nothing's blocked. the jet stream is going to continue to move those weather systems through and so, overall, a better spell of weather with some longer, drier, warmer spells, especially towards the south and east of the uk. still some rain around, especially across the north—west of the uk. that's your latest weather.

live from washington, this is bbc news. a stark new warning on climate change as ocean temperatures hit all—time record highs. the us food and drug administration approves the first pill for post—partum depression. and new concerns about the rise of anti—semitism in america after the pittsburgh tree of life synagogue shooting. hello, i'm helena humphrey. great to have you with us. there's been another dire warning about global climate change with scientists saying the average surface temperature of the world's ocean has hit a record high. it has risen to just under 21 degrees celsius,

or nearly 70 fahrenheit, in august — that's far above the average for this time of year and researchers say it could have serious consequences for the global environment. our climate editor justin rowlatt reports. i'v e i've been taking measurements of ocean temperatures here in plymouth for more than a century and for the last 50 or so years, they've shown a slow but steady increase, up about one third of the degree a decade. have we got a reading for today yet, do you know? i heard them say something around 18 or 19. wow! it's about four degrees higher than it should be. one of the most dramatic heatwaves ever recorded in uk seas hasjust subsided, part of a global trend of warming waters. 20.96 c, the highest global average sea temperature ever recorded. the world's warming waters are a dangerous trend, say experts. waters are a dangerous trend, say experts-— say experts. people's perspective _ say experts. people's perspective is - say experts. people's perspective is the - say experts. people's - perspective is the ocean, it is
