the headlines: a post—mortem in new york city has determined that the death of the disgraced us financierjeffrey epstein was suicide by hanging. us media had earlier reported speculation that epstein, who was awaiting trial on sex trafficking charges, could have been murdered. air travellers across the unites states have been facing major delays following a computer systems failure that caused chaos at airports. the us customs and border service says its computers are beginning to come back online and so far there's "no indication the disruption is malicious in nature." the veteran hollywood star peter fonda has died at his home in los angeles from lung cancer. he was 79. the actor, seen as a countercultural icon, was best—known for the 1969 film, easy rider, which he co—wrote and produced. now on bbc news,

it's time for click. this week: spotting early signs of dementia, giving the banks the finger, and man falls off skateboard. theme music. here is something that splits opinion, you either love these or you hate them. depending, really on whether you ride one, or whether you've had a close encounter with one. these e—scooters are powered by electric motors and that leads to something really interesting that

not many people know — in the uk, these things are not legal on public roads and they are not legal on public pavements. so although they are getting more and more popular, and companies are hiring them out to ride on private routs like here at the queen elizabeth olympic park in london, where they are and speed ltd, the law there is hugely around the world —— geofenced and their speed is limited. these can reach 30 miles an hour, which is very cool, or very dangerous, depending on your experiences with them. not long ago, presenter emily hundreds died while riding an is scooter. it was the first fatal collision involving one in britain —— hartridge. in france, there have been three personal light

electric vehicles —— three e—scooter deaths, and they are completely illegal in los angeles. is scooters, skateboards, there is a lot of confusion over the legality of these new modes of transport. here, at one of the busiest intersections at london, police are on the lookout for electrically powered scooters. these eco— friendly and easy to ride vehicles have exploded in popularity and are rapidly transforming the make up of road traffic in cities around the world. however, as spencer pointed out earlier, with tim e—scooters —— e—scooters easily available to buy in stores, many people don't know that they are illegal to ride on the road. why didn't the shopkeeper tell me? these

e—scooters are electrically powered, so e—scooters are electrically powered, so they are classed as motor vehicles, so you can't ride them on pavements or bike lanes. and to ride them on roads, you need insurance, which you can't get for these like of —— type of vehicles. if you get caught in the uk, you could get up to six penalty points on your license and a fine of up to £300. it's about education, about letting them know you can't ride these things on the road, you can't use these things on the road. recently, just down the road, there was a collision involving and is scooter and a 195 cc scooter. i think it sends a message that this needs to stop and the vehicles can only be used on private property or land. but, there is some confusion in the uk. the law states that personal

transport devices powered by motors are prohibited for use on roads, pavements and cycle lanes. however, in the different categories listed, they don't specifically mention e skateboards, and that is catching some people out. this man was stopped by the police on his way to work, given a written warning and, while he got away without the hefty fine, he was informed that his east edward was illegal to ride. the electric skateboard is in a grey area. the police told me and i was like what? i bought this, it cost me a lot of money, i've been writing for nearly five months now, no issues at all, nothing. no issues. and now from tomorrow, from this afternoon, i can't use it. there will be queries regarding electric skateboards as well as other types

of new transport. we recognise it was a growing trend with the use of e—scooters around london and awareness that people weren't necessarily educated that they are illegal to use on the roads and footpaths. so we have issued a numberfines and footpaths. so we have issued a number fines and also seizures of e—scooters, but we have taken that message that we would like to educate the public first and foremost and speak about why they actually are illegal to ride on roads, footpaths and cycling lands. however, the uk isn't the only country grappling with restrictions on light electric vehicles. in paris, authorities have put down strict regulations. from next month there will be a 12 mph speed limit and a 135 euros fine for riding on the pavements. there is even a fine for antisocial parking. but, for enthusiasts, these restrictions are the last thing they want to hear.

so, i've come to an event paris to find out what e—skateboarders from around the world think about the regulations imposed on them. the are so regulations imposed on them. the are so many different types of boards here, some can go up so many different types of boards here, some can go up to 50 mph! i don't know why you need to go that fast. people canjust don't know why you need to go that fast. people can just ride them and get to work, go shopping, do their normal lives. it is just such a better way to do these things. we wa nt to ta ke better way to do these things. we want to take because of the road, we wa nt to ta ke want to take because of the road, we want to take pollution of the road and have electric vehicles in. this is the future. regulations around the world are starting to tighten up stop there are limits to 20 kilometres per hour. can you imagine? there are no bike lanes in the city, and in paris there are no bike lanes in every street, so it is

very difficult. going 20 kilometres per hour on the street? your board can go 50 kilometres per hour? that's crazy! it is crazy, but you do have to have full production. -- protection. in melbourne, for instance, which is a really big scene in australia —— city, there is a policeman in that electric writers group, he cruises with everyone and there are no problems. what he says is as long as you are a reasonable citizen, you're behaving yourself, you wear protection, you are causing problems, nobody cares. it's safe, it's good as everyone's happy. so how safe are they? it can't be that ha rd to how safe are they? it can't be that hard to ride one of these, right? i'm doing that? ok. hard to ride one of these, right? i'm doing that? 0k. no, no, no. 0h no! as you see, it isn't the easiest

thing to use. and, even seasoned riders can have trouble staying on. this is the thing. people can just get a board, you don't need a license, you don't need insurance, it is that make it safe enough to drive out in the road, on the pavement? do need training or something first? i would just like to have a piece of paper that could say i can operate this thing safely, otherwise you would grass into something or someone. back in the uk, we contacted the department of transport and they told us they are actively examining how these late electronic vehicles can be regulated for safe use on the roads. but, for now, they are still illegal. so, this is michael. he's the one who first introduced me to e—skateboards and he is part of the community. so they are illegal to use on the roads and pavements. they are wrong. as a mechanically propelled vehicle they

are illegal on the road because we don't have things like insurance or licenses is devices. the problem is, there is no legislation out the moment for that, we can't get licenses or insurance and the raid that these boards are being used, legislation needs to be put in place so we can get insurance. it's not that we don't want to, if that we can't. whatever the cost, if it is legal, i would say go for it. wright, michael, thank you for chatting with me. appreciated. this is the bbc, it's private land. so i'm out of here! hello and welcome to the week intact. it's the week that face recognition software was found being used in kings cross, described as alarming by some, property developer argent says it uses the software to ensure public safety but could not reveal further details. just a few hundred miles

outside of hollywood, nasajpl limo's —— lima robot has been hard at work, scaling the steep wilds of california's death valley. and from outer space to inner self, meet this robotic buddhist priest. douglas adams was right. the electric monk now exists and is located in a kyoto temple in japan. it now exists and is located in a kyoto temple injapan. it is hoped that the robot will be able to attract more people to the essence of buddhist teachings. and prepare for a heavy night raving with a dj orbiting the earth. a life that was paid from the international space station to a ship full of clubbers.

he said he wanted to celebrate the common language of music. imagine being there when the base dropped from 250 miles. all right, let's talk money now, and more specifically, plastic. the last time technology does one of these things was more than ten years ago when they made them contact list. nfc or near field communication technology is really convenient, but not exactly secure. anyway, that is why they limit contactless payment to £30 or the rough equivalent in other currencies. that could be extended by quite a chunk of a new security feature is added. dan simmons has been invited to test the uk's first avocado can read your fingerprint. it's a big moment in the world of money. now western rbs star launching this —— natwest, although

the real—life ones will probably be smaller. and this should help wave goodbye to freud. what we are learning from customers as they want experiences to be simple and easy. this means they don't have to remember their pin, it means a safety a nd remember their pin, it means a safety and security perspective, they don't have to worry about standing it just point they don't have to worry about standing itjust point and someone seeing what their pin is. and within customers are seeing what their pin is. and within customers a re really seeing what their pin is. and within customers are really going to the experience. they not get an imprint? it isn't csi, it doesn't work that way. so a photograph? ifi go higher, they go, yes, enough pixels there? that won't work. on a glass, like police evidence kind of things? the powder? that doesn't work. no, sorry, your television dreams are shattered. if i find somebody has got my money but they shouldn't have, will you give it back to me? you can always block your card... is

that a yes? we review on a case—by—case basis. that a yes? we review on a case-by-case basis. right. i've got sort of like a card reader and the ca rd sort of like a card reader and the card itself. i'm going to need that little black box to kind of register my thumbprint onto the finger print reader. i've been invited to take pa rt reader. i've been invited to take part ina reader. i've been invited to take part in a three—month trial. the small battery and the reader is enough to power the card. after seeing my thumb from five different angles, it's happy it's got my print. now, of course google and apple pay systems using our mobile phones linked to our debit card and credit card offers similar biometric security payments. but your phone costs a lot more, needs to be charged and is a lot bigger. my new ca rd charged and is a lot bigger. my new card is no thicker than a standard debit card. a step downstairs what's

going on. on the right is the fingerprint reader, there is no battery inside, instead an inductive loop shown in red acting as an aerialfor the card to loop shown in red acting as an aerial for the card to receive power from the card terminal. the six dots at the top are the programming port. it is here, in the microcontroller, when my fingerprint is stored and verified. all in the card, so our biometric data never leaves our hand. a copy please. now using the card is much as easy as it is at the moment, except you have to put your thumb, is at the moment, except you have to put yourthumb, or is at the moment, except you have to put your thumb, or whatever finger you register, over the golden box, so it can recognise it when you make the payment. a green light flashes to show all is ok, and then my plastic is not in some trick the tv producer's hands. now the other big bonus i found is my new spending limit. normally, contactless payments out at £30. but this allows

me to spend up to £100 because of the additional security, and i am told that by the time it comes to market that limit could be limitless, which means i could get my weekly shopping, fill up my car, and buy a bikejust my weekly shopping, fill up my car, and buy a bike just with a tap of my card. so knowing all that, will the ca rd card. so knowing all that, will the card be secure? the centre we use is dynamic, which means that each time it reads yourfinger dynamic, which means that each time it reads your finger print there needs to be a 97, 90 8% match. if there is a scratch on your finger it will take that into account so next time it knows that will be there. but does then allow for someone with a similarfingerprint to but does then allow for someone with a similar fingerprint to get into the system? not at all, the variation is so small, there is no two people that would be within that level of variation. this would be the biggest change to payment cards ina the biggest change to payment cards in a decade, if the banks packet. —— back it. so the uk—based rbs and

natwest trial finished on wednesday, you met georgina buckley in the film, georgina, the trial has finished, what have you learned? we had great engagement from customers which was the purpose of the trial, they really enjoyed the look and feel of the card and the green led light when it works, that was positive from customers. and some of the retailers' technology needs to be upgraded to take biometric authentication which we did not expect. making these cards cost a bit extra, and you ask customers whether they would be paid for this. we did, we had mixed results from customers, some said they would be happy to pay a fee to have that increase authentication, and others we re increase authentication, and others were not. hopefully as we are able to roll it out more widely the average cost will come down, but we just have to see how that goes. assuming it all works, what is the next step of the plan? we are now going to launch biometric credit

cards, we will launch that pilot next month, and slightly different experience, we are not going to put a limit on it, so you would be able to use your biometric fingerprint up to use your biometric fingerprint up to the limit of your credit card. slightly different and we should get different feedback from customers, and again learn the positives, and the negatives and then use the pilot to fuel our innovation portfolio. and when can we expect these cards to be deployed for everyone to use? hopefully we can process the learnings later this year and then look at a broader rollout next year. there are currently an estimated 850,000 people living with dementia in the uk. and while the most commonly assumed symptom is forgetfulness, spatial awareness, perception and the ability to read faces a re perception and the ability to read faces are also hugely affected. laura has been looking at some logical approaches to better understand this condition. for those with apparent who have had what is known as frontal lobe dementia there is a 50—50 chance of

them developing it to. but a new study hopes to offer some promise for those at high risk by again defying brain analysis, and an earlier diagnosis would mean the chance to try and treat the condition sooner. —— gamifying. early detection of the manager is important because we understand that by the time people start to notice the symptoms of dementia like memory loss, it might actually be quite extensive changes in the brain. this app is actually developed for 30 and ao—year—old people to use, to help diagnose the possible early stages of dementia stop i have to say, i was a little bit nervous about doing this, because i was worried i was going to find out the thing i didn't wa nt going to find out the thing i didn't want to. but it seems that because it is still very early days of the trial, right now this will alljust come down to some anonymous data, so i won't actually get that answer back. but the questions are a mixture of whether you will get it right, the time you do it in, or whether you are going to be able to

finish each section in time. and it is from that that the decision as to whether you already have early—stage dementia or not can be made. whether you already have early—stage dementia or not can be madem whether you already have early—stage dementia or not can be made. it is a series of 18 different games which effectively test different cognitive functions. it might be executive function, visual, language, spatial, arithmetic, so the games are designed to test different areas of the brain. you also get symbols about —— benefits such as being able to measure timings and accuracy of when people answer things and how they enter things. so by being much more sensitive than paper—based testing system, again, you have got a hope of treating things. this is pa rt a hope of treating things. this is part of a year—long study. the test is taken every three months, as well asa is taken every three months, as well as a paper test at the start and finish. 20% of those taking part already have symptoms. the others are those with a 50% chance of developing frontal lobe dementia.“ we can show efficacy in the wider

dementia population, then that might be something that can be used at the front line by gps, but it is very important to do that alongside genetic counselling and all the other implications of a diagnosis. genetic counselling and all the other implications of a diagnosislj have other implications of a diagnosis.” have real hope that the app can help people with frontal lobe dementia by measuring sensitive changes in their cognition and as part of a wider study, that can be used to measure the effects of new and novel types of treatment and drugs to see if they are actually having a benefit or performance on these type of tests and apps. and of course it is not just the tests and apps. and of course it is notjust the patient tests and apps. and of course it is not just the patient whose life tests and apps. and of course it is notjust the patient whose life is affected. the loved ones it can be a hot racking and frustrating journey. and often one that is hard to comprehend. this is a vr experience that aims to put you in the position of the person who has dementia. to be able to help you provide a bit more empathy for a loved one or

simply understand more about the condition. use this voice. my daughter is talking to me, but the voice is saying they can't hear her. i feel very disconnected and i'm not sure if that is a deliberate part of the experience just because she is a person in virtual reality. why is she chatting on the phone... she is agitated and talking about dad again. is she talking about me? i think this is how not to treat a relative with dementia. no, i don't think it is time to be thinking about a home. apparently i have misheard and i want to go home, i don't feel safe. i have become a bit muddled, it certainly stirs up quite a reaction. ifelt frustrated, a bit confused at times, anxious and actually quite hurt by the way i was being dealt with by my daughter. so i think there is a lot going on in

the experience to think about but i really could do with the opinion of someone really could do with the opinion of someone who knows more than i do. tim has worked in dementia care for many years, and knows only too well the day today challenges and the importance of dealing with them sensitively. i willjust pop this cattle on the hob. it won't be long now. you can see the steam. what is that noise? dementia is notjust about losing your memory, it can affect your perception as well, so this vr app is about keeping track ofa this vr app is about keeping track of a particular sequence of events to something like making a cup of tea or taking pills, as we look at some of those rooms, some of the floors are shiny, and if your perception has been affected a wet floor. when we look like carpet that might look like shapes or animals moving in the floor, when we were the gentleman in the cafe with the

daughter and actually saying that he was not recognising the timing, and then she was on the phone and ignoring him and speaking about him as if he wasn't there, that's the wrong way to do it. you need to be with the person, they are there, they are a whole person, see the dementia. it brought the experience to life but importantly actually it showed what to do sometimes. what does this note say? for a condition so widespread, bringing home the reality could be really helpful. and while it may take decades to see whether early diagnosis will make a difference to the outcome, the research is a positive step in the right direction. providing hope for many thousands of people affected by something so devastating. two red, one blue. that is it for now. for the next few weeks we're going to be

recharging batteries, so we will give you the chance to see a couple of our favourite recent shows. we will still be here on youtube, facebook, instagram and twitter, so feel free to get in touch. thanks for watching and we will see you soon. hello there. we can all look forward to seeing some sunshine this weekend, it was a poor day though on friday, especially across england and wales, the wettest weather in snowdonia. that rain—bearing weather front is putting away from the south—east of england but this area of low pressure is going to be the one constant right the way through the weekend. that will focus the showers towards the north—west of the uk — some of them will be heavy. we'll get some sunshine, yes, but they will be accompanied by some blustery winds as well. those showers continue into the morning, these are the temperatures first thing,

12—15 degrees, but some heavy showers from overnight especially in scotland and the north—west of england. it will be western scotland and northern ireland that sees the bulk of the showers on saturday, wetter weather in the north—west and the winds really picking up later on. one or two fleeting showers for england and wales but not many, good chance it will stay dry at lord's for the cricket, but we will have these strong winds, not as strong as last weekend, and those temperatures back into the low 20s now that we have the sunshine across eastern parts of england. those showers, though, continue in scotland and northern ireland again, heavy and thundery, gusty winds as well, we have thickening cloud across southern counties of england, maybe threatening a bit of rain. in between, clearer skies and temperatures around 11—13. the wetter weather in the south and south—east courtesy of this weather front here, that should pull away on sunday morning. still got that area of low pressure, it is a bit closer to scotland this time, and again it will focus the more frequent and heavy showers into scotland, into northern

ireland, again some thundery downpours, gusty winds too, probably a few more showers in northern england, north wales, the south—west of england the best of the sunshine, and dry weather through the midlands and eastern england. strong, gusty west to south—westerly winds, probablyjust taking the edge of the temperatures but sunday is probably going to feel quite similar to saturday. as we head into the beginning of next week, we still have an area of low pressure but it is starting to move away from scotland slowly but surely, the winds beginning to ease down a bit as well. there will still be a focus of heavy showers across scotland and northern ireland, and a few scattered showers coming into england and wales, always heavier further north. some spells of sunshine around again and those temperatures are still 16 degrees in the central belt, to a high of 21 or so in the south—east of england. further into next week, we will find some spells of sunshine. warm in the sunshine, temperatures not particularly impressive for the time of year, there will be some showery bursts of rain, mainly in the north

and west, the winds, though, should be lighter.

welcome to bbc news. i'm reged ahmad. our top stories: medical officials in new york say the death of the disgraced financierjeffrey epstein was suicide. air travellers across the unites states are facing major delays as a computer failure causes chaos at airports. crowds gather in hong kong as the city braces itself for another weekend of protests — but police say they're still in control. we all face tremendous pressure, but i can tell you we are confident that we have the capability to maintain law and order in hong kong. and the hollywood actor, peter fonda, famous for the film classic easy rider has died at the age of 79.
