time for a round—up of your sport now. here's gavin. i wonder what he can tell us about the cricket and the rugby. good afternoon. good afternoon. england have a wicket at lord's, in their attempts to bowl australia out, in the 2nd ashes test. australia now 134—5 in the first session of day four. stuart broad getting his third australian wicket. this time matthew wade, going for 6. steve smith is still in, though england trying to cause as much damage as possible, after rain forced most of yesterday's play to be abandoned. updates on the bbc website on that one. the first of the day's premier league matches is about to kick off — it's arsenal against burnley — david luiz and dani ceballos are making their full debuts for arsenal, but mezut ozil is still absent. burnley‘s line—up is the same 11 that started last

weekend, in their opening win against southampton. there's text commentary on the bbc sport website. liverpool's adrian is hopeful of starting against southampton this afternoon, despite being injured by a fan who ran onto the pitch during the team's super cup celebrations. adrian made his debut in the win over chelsea on wednesday, with regular keeper alisson injured — and managerjurgen klopp had this to say to the unwelcome pitch intruder. there is no doubt about how much we love our fans, there is no doubt about that. but if they could all stop doing that, doing... that's now the worst example i've so far heard about. it's not funny. what can i say? i don't know what you can do against it but it's not... i like the fact that we don't have fences in the stadium but that means there's a lot of responsibility for the supporters as well. bath winger ruaridh mcconnochie is out of the england team to face wales this afternoon in a world cup warm—up match.

he was set to make his debut in cardiff but he has a muscle strain — he's replaced in the starting 15 by club—mate anthony watson. england beat wales at twickenham six days ago and wales boss warren gatland says his players now have to prove themselves to secure a world cup spot. there is a lot of pressure on those guys on the weekend because if some of those don't front and don't perform then they are opening the door for someone else. you win last week and this weekend, you have potentially sealed a starting spot for the first game of first couple of games in the world cup. scotland are in far better shape than they were in the spring, after a six nations championship hampered by a string of injuries.... they take on france later in nice. head coach gregor townsend appreciates the chance these warm—up games give, to study how his players perform. the positive about these games is you can focus a lot more on yourself.

we've not done that much analysis on france. they've changed their coaching staff or added people to their coaching staff so they changed the way they play. we just want to make sure we get our systems, defence, attack, how we want to win the game and how our players show their strengths. world champions new zealand have emphatically bounced back from last week's record test defeat to australia. they hammered their rivals 36—0 in auckland, with a really polished performance, richie mo'unga scoring 14 points, including the opening try — although there was cause for concern later when he was forced off the field after a heavy tackle. sevu reece kicked through to finish off the pick of the tries in the second half. it's the 17th season in a row that new zealand have lifted the bledisloe cup. you're up to date with the sport — now, it's time for click.

this week — spotting early signs of dementia, giving the banks the finger...print, and man falls off skateboard. here's 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're getting more and more popular, and companies are hiring them out to ride on private lands like here at the queen elizabeth olympic park in london, where they're geofenced and speed—limited, the law varies hugely around the world. one of the issues is that these things can reach speeds of over 30 miles an hour, which is very cool, but also very dangerous, again, depending on your experiences with them. not long ago, presenter emily hartridge died while riding an e—scooter. it was the first fatal collision involving one in britain. there have been similarfatal cases around europe. in france, there have been three e—scooter deaths in the last four months, and there have even been deaths in los angeles where these are completely legal. so, whether it's e—scooters, segways, one—wheelers or e—skateboards, there's a lot

of confusion over the legality of these new modes of transport. as omar mehtab has been finding out. here, at one of the busiest intersections in london, the metropolitan 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 e—scooters freely available to buy in stores, many people don't know that they're actually illegal to ride on public streets. when i bought it online they should have told us that there are legal to ride here. i mean, ijust spent £500 for nothing, basically. the problem is, these e—scooters are electrically powered, so they're classed as motor vehicles, which means you can't ride them on pavements or in bike lanes.

and to ride them on roads, you need insurance, licensing, tax. things you can't get for light e—vehicles at the moment. and if you get caught? well, in the uk, you could get up to six penalty points on your driving license and a fine of up to £300. stop today was just 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 on rosemary avenue, was a fail—to—stop collision involving an e—scooter and a i25cc scooter. i think it sends out the message that this needs to stop and the vehicles can only be used on private property or land. but, there's 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 e—skateboad was illegal to ride. all the information i can find is that this one's are not illegal, like the electric skateboard is in the grey area, kind of, there's not really legislation that actually bans it. until today, you know? and the police told me and i was like what? i said i bought this, it cost me a lot of money, i've been riding it for nearly five months now, no issues at all, no accident, no issues. and now from tomorrow, i think from this afternoon, i have to take underground, exactly. there will be queries with regards to e—skateboards as well as e—scooters and other types of powered transport but we recognise there was a growing trend with the use of e—scooters around london and awareness that people weren't necessarily educated

to the fact that they are illegal to use on the roads and footpaths. so we have issued a number fines and also seized some e—scooters, but we are maintaining that message that we would like to educate the public first and foremost and sort of spread that message wide that they are actually illegal to ride on roads, on the pavement or in cycle lanes. however, the uk isn't the only country that's grappling with restrictions on light e—vehicles. in paris, authorities have put down strict regulations. from next month there will be a 12 mph speed limit and a 135 euro fine for riding on the pavements. there is even a 35 euro 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. there's tons of people here! the are 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 can just ride and then get to work, go shopping, do their normal lives. it is just such a better way to do these things. we want to take cars of the road, we want to take pollution of the road and have electric vehicles in. because this is the future. regulations around the world are starting to tighten up. they will are limits to 20 kilometres per hour. it's really slow! 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 up to what, 50 kilometres per hour? that's crazy! yeah.

it is crazy, but you do have to have full protection and try it on the street without any cars and make sure it's safe. in melbourne, for instance, which is a really big scene in australia. there is a policeman in that electric skateboard riders' group, he cruises with everyone and there are no problems. because what he says is as long as you're a reasonable citizen, you're behaving yourself, you wear protection, you're not causing problems, nobody cares. it's safe, it's good and everyone's happy. so how safe are they? it can't be that hard to ride one of these, right? i'll put a little bit of throttle on. oh, are you doing that? i'm doing that. 0k. ahaha! no, no, no. no! aaah! and as you can 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 know, you don't need a license, you don't need insurance. so then does that make that safe enough to drive out in the road, or on the pavement? do need a little bit of training first or something? orjust a piece of paper to say, yes, i can operate this thing safely. because then otherwise you're gonna crash, you know, into something or someone. back in the uk, we contacted the department for transport and they told us they are actively examining how these light 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 a part of the community. so, that is the official line of the met, they're illegal to use on the roads and pavements. what do you think of that? i mean, they're not wrong. as a mechanically—propelled vehicle they are illegal on the road because we don't have things like insurance or licensees for these devices. the problem is, there is no

legislation out the moment for that, so we can't get insurance, we can't get licenses, and at the exponential rate the boards are being used, legislation needs to be put in place so we can get insurance. it's not like we don't want to, it's just that we can't. if we can legally ride on the roads with every other road user, whatever the cost, if it's legal, i'd say go for it. right. michael, thanks a lot for chatting with me. appreciate it. now, this is the bbc, it's private land. so, i'm out of here! hello and welcome to the week in tech. it's the week that face recognition software was found being used in london's king's cross. described as alarming by some, property developer argent says it uses the tech to ensure public safety but did not reveal further details. meanwhile, just a few hundred miles outside of hollywood, witness nasajpl‘s lemur climbing robot hard at work. this 16—fingered cybernaut has been scaling the steep walls

of california's death valley. and from outer space to inner self, meet mindar, the robotic buddhist priest. yes, douglas adams was right. the electric monk now exists and is available for sermons at kyoto's kodaiji temple injapan. based on kannon, goddess of mercy, lord of compassion, it's hoped the chilled—out android will help attract more people to the essence of buddhist teachings. ah, some gentle meditation, a great way to prepare for a heavy night raving with a dj that's truly out of this world — orbiting the earth at about 17,000 mph. italian astronaut luca parmitano played a live set from the international space station to a cruise ship full of clubbers. the first dj in orbit took lessons prior to going into space, saying he wanted to celebrate the common language of music. imagine being there when the base

dropped from about 250 miles. right, let's talk money now, or more specifically, plastic. now, the last time technology touch one of these things was more than ten years ago when they made them contactless. wave—and—pay uses nfc or near field communication technology and it's really convenient, but not exactly secure. not if you have your wallet nicked. anyway, that's why they limit contactless payments to £30 or roughly the equivalent in other currencies. but that limit could be extended by quite a chunk if a new security feature is added. dan simmons has been invited to test the uk's first debit card that can read your fingerprint. it's a big moment in the world of money. natwest and rbs are launching this — although the real—life ones will probably be smaller. and they should help wave goodbye to fraud.

what we're learning from customers is they want experiences to be simple and easy. this means they don't have to remember their pin, it means from a safety and security perspective, they don't have to worry about standing at a cash point and someone looking over their shoulder and seeing what their pin is. and we think customers are really going to the experience. could they not get an imprint? no, it's not csi, it doesn't work that way. it doesn't? 0k. so, a photograph? nope. if i go hi, theyjust go, oh, yes, excellent there's enough pixels there and nick that? that won't work. on a glass, you know, like police evidence kind of things? the powder? no, that doesn't work. no? nothing? no, sorry, your television dreams are shattered. if something goes wrong and i find that somebody‘s got my money but shouldn't have my money, will you give it back to me? what you can always do is block your card with one phone call. is that a yes or a no, georgina? we review all customer experiences on a case—by—case basis. right. it's arrived.

i've got a 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 on the fingerprint reader. i've been invited to take part in a three—month trial. the small battery in 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 a debit card and credit card offer similar biometric security for payments. but your phone costs a lot more, needs to be charged and it's a lot bigger. my new card is no thicker than a standard debit card. a strip down of it shows what's going on. on the right is the fingerprint reader, there's no battery inside, instead an inductive loop shown in red acts as an aerial for the card to receive power

from the card terminal. the six dots at the top are the programming port. and it's here, in the microcontroller, when my fingerprint is stored and verified. all on the card, so our biometric data never leaves our hands. a coffee please. now using the card is pretty much as easy as it is at the moment, except you have got to put your thumb, or whatever finger you've registered, over the golden box, so it can recognise it when you make the payment. a green light flashes to show all‘s ok, and that's my plastic is not in some trickster tv producer's mitts. now the other big bonus i found is my new spending limit. normally, contactless payments cap out at £30. but this allows me to spend up to £100 because of the additional security, and i'm 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 with a tap of my card. so knowing all that — will the card be secure? gemalto is behind the tech. the actual sensor we use is dynamic, which means each time it reads your fingerprint it needs to be a 98—99% match. if there is a slight variation, a micro slash on your finger it will take that into account, so next time it knows that micro—slash will be there. but does it then allow for someone with a similar fingerprint to get into the system? no, not at all, the variation is so small, there is not two people that would be within that level of variation. this would be the biggest change to payment cards for a decade, if the banks back it. so the uk—based rbs and natwest trial finished on wednesday. you met georgina buckley in dan's film, georgina,

the trial has now 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 lights when it works, that was really positive from customers. love a flashing light. and some of the retailers‘ technology needs upgraded, essentially to take biometric authentication which we hadn't expected, and that was a really good learning. making these cards obviously costs a little bit extra, and you asked customers whether they would be willing to pay for these cards. we did, we had mixed results from customers, so some said they would be happy to pay a fee to have that increased authentication, and others weren't. hopefully as we are able to roll it out more widely the average cost to produce them 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 out biometric for 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 the limit of your credit card.

slightly different and we should get different feedback from customers, and again learn the positives, learn 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? well i'm hoping 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 are also hugely affected. lara lewington has been looking at some technological approaches to better understand this condition. for those with a parent who has had what is known as frontal lobe dementia, there is a 50—50 chance of them developing it too. but a new study hopes to offer some promise for those at high risk by gamifying brain analysis,

and an earlier diagnosis would mean the chance to try and treat the condition sooner. well early detection of dementia is important because what we're beginning to understand is that by the time people start to notice the symptoms of dementia like memory loss, there might actually be quite extensive changes in the brain there. this app is actually developed for 30 and 40—year—olds to use, to help diagnose the possible early stages of dementia. i have to say, i was a little bit nervous about doing this, because i was worried i was going to find out somthing i didn't want to. but it seems that because it is still very early days for the trial, right now this will alljust come down to some anonymised 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. it is a series of 18 different games which test effectively different cognitive functions. it might be executive function, socialfunction, visio—spatial, language, arithmetic, so the games are designed to test different areas of the brain. you also get lots of simple benefits such as being able to measure timings and accuracy of when people answer things and how they answer things. so by being much more sensitive than paper—based testing system, again, you have got a hope of treating things. this is part of a year—long study. the test 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. if 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 of course it's very important to do that alongside

genetic counselling and all the other implications of a diagnosis that come with it. i have real hopes for the ignite app, that can help people with frontal temporal dementia by measuring sensitive changes in their cognition and their thinking that go with the early stages of the disease, 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 in the performance on these type of tests and apps. and of course it is notjust the patient whose life is affected. for loved ones, it can be a heartbreaking 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 i can't hear her. i feel very disconnected from her and i'm not sure if that is a deliberate part of the experience orjust because she is a person in virtual reality. bob will be wanting his lunch at one... why is she just chatting on the phone? she's not paying me proper attention. she's agitated and talking about dad again. is she talking about me? i think this is probably how not to treat a relative with dementia. no, i don't think it's time to be thinking about a home. oh goodness, apparently i have misheard and i want to go home, i don't feel safe here. i have become a bit muddled. well, it certainly stirs up quite a reaction. i felt 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 quite a lot going on in the experience to think about, but i 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—to—day challenges and the importance of dealing with them sensitively. i'lljust pop this cattle on the hob. it won't be long now. you can see the steam. what's that noise? dementia is not just about losing your memory, it can affect your perception as well. so this vr app is about keeping track of a particular sequence of events to something like making a cup of tea or taking your pills. the reality is as we look at some of those rooms, some of the floors are shiny, and if your perception has been affected that could look like a wet floor. when we look like a patterned carpet, that might look like perhaps animals or shapes 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, he thought he was going home for lunch, 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 person, not the dementia. it really 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's it for now. for the next couple of weeks we're going to be recharging our batteries, so we will give you the chance to see again a couple of our favourite recent shows. we will still be here though, on the end of youtube,

facebook, instagram and twitter, at @bbcclick. so feel free to get in touch. thanks for watching and we will see you soon. in western scotland and northern ireland today, frequent blustery showers, even rumbles of thunder and strong winds around the coast, costing up to 50 miles an hour. for the vast majority of the uk, it is a lot better than it was yesterday. the weather front is moving off. we still have a scattering of showers and clouds. most of the showers will be in the north—west. and more especially in the

north—west here. top temperature today in the low 20s. this evening, clear skies across england and wales, but later tonight there will be more rain in the south of the country. it may end up a wet night in the extreme south—east of england. still a breezy day in the north tomorrow with further showers, but once again across england and wales, the weather is not looking bad at all with the top temperature tomorrow around 21.

good afternoon. detectives are continuing to question ten people, aged between 13 and 30 years old, arrested on suspicion of murdering a police officer in berkshire. 28—year—old andrew harper, was responding to reports of a burglary, when he was dragged along a road by a vehicle. this morning, officers laid flowers at the scene. simonjones reports. married just a month ago, pc andrew harper was looking forward to his honeymoon. now, though, his death is the subject of a murder
