scheduled so far. also, millions of americans face floods and high winds — after southern california is hit by the first tropical storm in 80 years. scientists in london develop an artificial intelligence tool that can reveal exactly how much an unhealthy lifestyle can prematurely age your heart. we'll see how it works. on our panel tonight, rebecca harding — independent trade economist. and miles taylor — former republican, homeland security official. donald trump says he won't be at the republican party primary debates. first is wednesday in milwaukee. he made the announcement on his social media platform truth social. he says he won't be there because "the public knows who i am and what a successful presidency i had". look at the latest poll from our partners cbs news. trump is way out in front of his republican rivals. 62%. nearest challenger mr desantis, who sat on 16%. donald trump favourite to become republican party nominee for next presidential election. joining me now is aaron kall, director of debate at the university of michigan. what do you make of this move by donald trump? controversial, with the polls with such a lead, there's not much incentive for him to get involved in the debates, because doing so would give a platform to his opponents, make him a target at the debates, and elevate those other candidates who are pulling much lower, so as long as he continues to have such a large leader looks like he will be the republican nominee, determined that there is no reason for him to participate in subjecting to those risks at this time, but it is always subject to change.— risks at this time, but it is always subject to change. sub'ect to change. that's the kind of subject to change. that's the kind of olitical subject to change. that's the

very important, they are historical, there watched by tens of millions of people, so for the good of the country and democracy, the civil exchange of ideas and policies, it would be great for all of our front runners, but as you have seen, he is controversial in that respect, experiencejanuary controversial in that respect, experience january 6, and he has stressed democracy in the right of states many other ways, more conventional candidates, there is no political experience, may have the greater valour and do it, but for him it isjust a pure, cold calculation, what gives him the best chance to be the nominee, win the election may be stay out ofjail. these are important decisions, very high stakes rent to make. let’s these are important decisions, very high stakes rent to make. let's look at the debates _ high stakes rent to make. let's look at the debates as _ high stakes rent to make. let's look at the debates as they _ high stakes rent to make. let's look at the debates as they go _ high stakes rent to make. let's look at the debates as they go ahead - at the debates as they go ahead without him, is there any way you could spin it that actually this could spin it that actually this could be a really big opportunity for the other candidates, if trump was out the debate, he would suck out all the attention and get all the media coverage. without him there, there is a chance to someone to stand up tall, put their head up, get a bit of coverage, do well in a challenge. get a bit of coverage, do well in a challenue. , , get a bit of coverage, do well in a

cooperate with that, they have the autonomy about which questions they ask and how frequently trump is mentioned, so if they make him a footnote of the debate then yes that will get the opportunity of the other candidates. the front runner always gets the most time, so if you are participating in the debate, he would probably have got 30, 45 minutes to him, this gives opportunities to number two, rhonda santos, chris christie, all of them are trying to emergence the solid number two, are trying to emergence the solid numbertwo, get are trying to emergence the solid number two, get a head—to—head contest, to perform well and try and set up their contest in the future. we are going to bring our talented, but fully do, breaking news and donald trump, just before we ride in the debate down, a court in georgia has set bond for former us president donald trump at $200,000, a $200,000 bond forformer us donald trump at $200,000, a $200,000 bond for former us president donald

millions. southern california was hit by its first tropical storm in 80 years. storm hilary downgraded to a post tropical cyclone. but look at the destruction. we're going to focus on these areas — los angeles, palm springs and neighbouring cathedral city, death valley and nevada's las vegas. these are the latest pictures from the affected area. they show the devastation caused in cathedral city. cars have been abandoned in vast quantities of mud as the flood waters recede. in los angeles — some of the iconic hollywood locations were hit by storm hilary. the icon on the screen is because these pictures are taken from snapchat. the hollywood walk of fame there. and look at these pictures from death valley. very hot, now inundated with the water. so unusual to see these pictures there. this is las vegas — the rain there has triggered severe flooding. hundreds of flights have been cancelled at airports in the city. in victorville, near los angeles, some people watched floodwaters inch closer to their home — before making the decision to leave. all that started within an hour or two, and kept piling up and the water kept coming further back up the street, and just more and more. lives can't be replaced. material objects can. it's better to just replace a house and fix whatever gets damaged than to get somebody drowning over something that's avoidable. can't disagree with that. california's governor gave this update on the many problems now being tackled by the state's emergency services — a little earlier. there is an old, ancient curse that loosely is translated as, may you live in interesting times. it is certainly interesting times. tornadoes, lightning strikes, i've got cal fire worried about wildfires because of the winds, not just the tornadoes. i had a walk around emergency services, checked my phone to learn about an earthquake that originally came at 6.0 was that it is to be closer to 5.1. there were over 13 aftershocks just in the drive over the region. these are certainly interesting times. jon baird, reporter at knx news in south california, gave us the latest from los angeles. the situation is much improved over the last few hours. the rain is gone, the sun has finally come out, i don't see any winds, but i notice up the street here, i am in sun valley, the north part of la, we are seeing a lot of water still running down the gutters, you fly through an intersection, it's like a boat with all the water splashing up, so there is still plenty of water running, flooded areas across the entire region, especially out in the deserts, as you heard, and there's going to be a lot of clean—up to be done. ijust came from a house where a tree just split in half, a huge tree, came down, fortunately not on a house, because there were four or five or six people, a whole family in there, it came down on the two cars and crush them like a couple of bugs. we've had trees down, and power lines, and now, really, the clean—up begins. what have been the worst hit areas there across southern california? i would have to say the desert areas. we had some intense storms, as you know, over the wintertime, we had some of the most rain we've ever had in four decades, rain and snow, we got hammered. so, people compare this storm to that one, we did get a lot of rain in a short period of time across the entire region, but i think the desert areas like palm springs were hit the hardest. i worked there as a young reporter, i started there on tv, and i remember an august day when it was sunny and nice in the morning, by noon it clouded up, and at two o'clock half a block down the street from the station cars are being swept away by floodwaters. that's how fast it can happen. that's what the danger is. so, what are the authorities there now, what is the scale now of what they have got to try and do now? well, i think there is a lot of clean—up, but i don't know that this is really a whole lot different clean—up—wise than what we went through in january and february when we were just hammered by storm after storm after storm. they've got the streets and the power lines and the trees to deal with, the flooded areas in palm springs, i don't know what that will involve, that could be a long time, a long—term project. we've been through this before, even though we haven't had, technically had, a tropical storm in la in 84 years. had, a tropical storm in la in 84 ears. ., ., ., , ., years. looking forward now before i let ou years. looking forward now before i let you go. — years. looking forward now before i

the worst of it is over. l probably attended four or five hours ago, but the rain, even at 4am california time, the rain was intense and driving was really dangerous, and i have to tell you, that's what the big danger is when it rains in los angeles, we have tripled the number of car accidents on the freeways that we do when it is not raining. itjust really slick, and you end up hydroplaning and slamming right into a freeway wall. rebecca harding, independent trade economist, joins us now, along with miles taylor, former republican and former homeland security official. sta rt start with you, miles, your country is no stranger to big extreme weather. how is this being judged? well, it's an extraordinary event, the department of homeland security, the department of homeland security, the federal emergency management agency that manages these crises, this is really different than other tropical storms that they deal with, because normally tropical depressions form over warm water on the other side of the country, they come up to the gulf of mexico, up through the atlantic in the hit at seeboard which tends to be much better prepared for these events as a result, in fact every single year during hurricane season you see the east coast of the united states preparing. as reported, we haven't seen anything like this and close to a century in california because you have cold water in the pacific, you don't see these types of systems developed very often. it's an anomaly, and as a result you often have a population it's really, really unprepared for it. the people are prepared, the infrastructure is prepared, and often the emergency services arrive well, that's what we have seen in california, and it's still early stages. right now we don't have a full scope of the devastation of damage, that will be the type of thing that takes days, weeks and often wants to try and figure out. weeks and often wants to try and fiaure out. , m, weeks and often wants to try and

further action after investigating a charity set up by king charles while he was the prince of wales. it began investigating the prince's foundation following newspaper allegations that a saudi donor was offered help getting an honour. the met said it had chosen to close its investigation after consulting the crown prosecution service. a man has appeared in court charged with terrorism offences linked to a major data breach by the police service of northern ireland. the names of more than 10,000 officers and staff were released by mistake. it's alleged that christopher paul 0'kane, from londonderry, had a spreadsheet containing officers' names at his home. he's been remanded in custody. the number of pothole—related breakdowns is at a five—year high, according to the aa. it says call—outs linked to potholes were up by a fifth injuly, compared tojuly a year ago, with over 50,000 vehicles breaking down last month. you're live with bbc news. a new ai tool can reveal the ageing affect on our hearts of a lack of exercise, poor diet, drinking and smoking. it allows doctors to work out how much younger or older someone's heart is compared to their actual age, as our science correspondent pallab ghosh has been finding out. heart beats. this is a heart scan of a 61—year—old person, but the chances are that the heart itself is older and has aged prematurely because of their genes or unhealthy lifestyle. not even experts can tell from the scan how much the heart has aged, but a new ai tool can. there are already plenty of ways to assess how healthy our heart is through scans, blood pressure, ecgs. but these just give you a snapshot and can vary from day to day, month to month. but this new ai technique is different. it can give you an accumulated total of all the bumps and scrapes your heart has had through lack of exercise, poor diet, smoking and drinking. let's see how i get on. the first step is to have an mri scan after some gentle exercise. machine: breathe out and hold your breath. | the scientists record pictures of my beating heart and the ai system analyses it. i'm 61. but how old is my heart? it says that your heart age is 63. oh, well, that's a bit older than i actually am. so how does that figure? what should i do? exercising enough, watching your weight, smoking and so on. and of course, we're interested in looking at treatments that might slow down ageing or might reduce the effects of ageing. and these sorts of scans can quantify that and see how effective those treatments might be in the future. and here's the next step. 256 sensors are creating what is, in effect, a digital copy of this volunteer�*s heart. you can see how the electrical activity is flowing through it. these digital experiments will transform the way we conduct health care. it will be possible for scientists to use these resources to test the impact of drugs, new cardiac devices, lifestyle interventions, and importantly, to predict each individual's personalised risk. heart research is now in the digital world, with al and machine—learning techniques already developing the next generation of treatments to keep us healthierfor longer. pallab ghosh, bbc news. let's get the thoughts of the panel on this. miles and rebecca are there. rebecca, ai is getting everywhere, isn't it?- there. rebecca, ai is getting everywhere, isn't it? yes, it is, there is a _ everywhere, isn't it? yes, it is, there is a lot _ everywhere, isn't it? yes, it is, there is a lot of _ everywhere, isn't it? yes, it is, there is a lot of debate - everywhere, isn't it? yes, it is, there is a lot of debate about . everywhere, isn't it? yes, it is, i there is a lot of debate about the dark side of ai, but this is one of the uses where ai can really be used to increase and advance human health, and i think you have to say that's the correct use of ai. it's basically using the behaviours of the heart, to forecast how to behave in the future, and i think so we can develop more effective treatments. really impressive. miles, do you want to know the age of your heart? i absolutely do not want to know the answer _ i absolutely do not want to know the answer to _ i absolutely do not want to know the answer to that question, because i think— answer to that question, because i think it _ answer to that question, because i think it would shock all of

[it is because of the application of ai. it is extraordinary, isn't it? it's not just the area of health, where we can see the benefits quickly, but you can have the most experienced doctor in the world looking through various different images, and simply isn't enough time or cross—referencing ability to do the specificjob cross—referencing ability to do the specific job that this cross—referencing ability to do the specificjob that this technique does. rebecca, why, more widely, one of the more things that affect you and structure ai so far, the pace with which it has been developed? brute with which it has been developed? - used to have something called moore's law where we said the powers of the processor would double every two years, and we have seen that at just dramatically, it's exponential, the entire market now being worth more than 2 trillion in a couple years' time, we are seeing ai advance at a very rapid pace, what we're seeing more broadly in al, as we're seeing more broadly in al, as we go into the beginning of a new technology, a new wave of the whole way in which we organise our lives, people have the ethical conversations as well, and i think it's important that we keep those at the front of our minds, because we could just sleepwalk into something, you could think about genetic engineering 20 years ago, people thinking about designer babies and frankenstein babies, we could do down the same route, and i think now we have a real opportunity to do something good.— we have a real opportunity to do something good. great to have you on, we something good. great to have you on. we were _ something good. great to have you on, we were back _ something good. great to have you on, we were back with _ something good. great to have you on, we were back with you - something good. great to have you on, we were back with you both - something good. great to have you| on, we were back with you both and just a couple of minutes. hello. a fairly quiet evening out there for most of us after what has been a pretty decent monday with some sunny spells. just a few showers here and there. and i think that's what we're going to get tomorrow — scattered showers with plenty of sunny spells as well. but having said that, there is thicker cloud and some outbreaks of rain across the north—west of the country. this small weather system has swept into northern ireland and scotland. so through the course of the evening and night, closer to this area of low pressure, it will be raining at times, whereas the south of the country is under the influence of a high. so, here, the skies will be generally clear. so through the evening and the night, that weather front moves into the north—west, a spell of showers, a stronger breeze as well, but most of england and wales should have dry weather overnight. and the early morning temperatures, whether you're in the north or the south, will be around 14 or 15 degrees. a fairly mild start to tuesday. so here's the forecast, then. closer to the low pressure here, which is to the north of scotland, a thicker cloud at times, again, a scattering of showers. i think the south of the country and the south—east will be generally dry and bright, if not sunny, and, again, every bit as warm as monday. so highs of about 25 in london and norwich, 21 expected in liverpool and about 20 or so in belfast. and tuesday is also going to be very warm across much of europe. here in the uk, typically the 20s, but further south, just across the channel, we're hitting the mid—30s, even in excess of 40 degrees celsius in places like lyon. back to the uk, then, midweek, we have some cloud again spreading into the north—west of the country, perhaps some other western areas of the uk as well, so the dry and brighter weather will be always further east and south. again, the mid—20s, so similar temperatures most days. in the north—west, around 19 or so. so is this warmth going to last? well, the low pressure and the jet stream are right over us towards the end of the week, so anything south of the jet stream is pretty hot, anything north of the jet stream — and more or less underneath it — is generally on the cool side. so it is expected to cool off as we head towards the end of the week, through the weekend and into next week. so no longer the mid—20s in the south, it's going to be closer to about 20 or so. but the high teens still expected further north. bye— bye. him him hello, i'm lewis vaughanjones. you're watching the context on bbc news. spain's players return home to a heroes' welcome — after winning the women's world cup for the first time. we are to head to ecuador with the presidential election happening there. second round of voting where she will face daniel nouveau, that will take place in october. of course you may well know that this election campaign has been overshadowed as one of the candidates was shot dead, murdered out on
