speaking, it will be a little mild we are temperatures holding up in the west. favoured spots eastern scotla nd the west. favoured spots eastern scotland and north—east england. tomorrow a band of cloud bringing drizzle to northern england and wales. top temperatures on sunday of seven to 11 degrees. take care. hello this is bbc news with shaun ley. the headlines. a man has been arrested in connection with the murder of a passenger on a train in surrey yesterday. a woman has also been arrested on suspicion of assisting an offender. smokers and problem drinkers admitted to hospital in england will get help to quit or cut down —— to try to reduce demands on the health service. in the united states, three people have been shot dead at a bowling alley in torrance, near los angeles. witnesses say there was a fight before shots were fired. ryanair has been voted the worst short—haul airline for the sixth year in a row — in a survey by the consumer group which.

rya nair has described the result as "irrelevant". now on bbc news, it's time for click. music plays. yeah, we did all that and more last year, and this week we're going to look back at some of our favourite moments,

and also look ahead to what we might expect from 2019 — which doesn't quite roll off the tongue yet, does it? 2018 was a great year for sports — the world cup, formula one and of course, cycling's tour de france, and we delved into the technology behind them all. this year's tour de france is taking place amongst the same beautiful mountains as always. but there's a big difference this year. technology and data is playing more of a role than ever before. cycling is becoming increasingly data—driven. and for good reason. masses of data can be collected. and in a sport of fine margins and superhuman endurance those insights are the key to energy efficiency, strategy, and gains. we look at many things, we look at heart rate, at power data, their maximum powers and their altitude and elevation gain. so we look at that and we see how

the riders are building and we leverage that data to try to build them to be better and stronger in stage races. but how is the data collected and transmitted 7 that's where these devices come in. the sensors on the bike send real—time location data to a nearby vehicle, which then beams it up to a following helicopter. it's then sent to the data truck for real—time analytics. the data truck is where data is analysed, enriched, and visualised for broadcasters and teams. there's even enough data for machine learning algorithms to get to work. the depth of data analytics produced from simply a gps device is staggering. contextual data such as 3—d maps, weather, gradient and rider information is also added to bring the data to life. during the race, riders wear earpieces, and following close behind them is the data car, where the team analyst is dissecting the data and feeding them live information. and so what happens in here,

it's quite an important place, isn't it? imagine if you have a comms office when you're trying to fly a rocket to the moon, and just feel like we're that place in nasa where all the details come in and they come in from all directions, and then we send out one message to the riders. hundreds of datasets are analysed, from competitor tactics to live course conditions. so we analyse all the climbs, the gradients of the climbs, the road surfaces, the width of the road, any road furniture, anything — you know, coming round a blind corner and there's a pedestrian crossing, all of these sorts of things we try to find. on the tour de france, with restrictions and sponsorship deals we don't get any heart rate power data, but we do get location, which is absolutely crucial, because we can make decisions much, much quicker. we are in the race. this is happening, this is live. what are we saying to the riders? come on, serge, you have got 250 more metres, hard. around the next corner, the hairpin, it flattens off at 250 metres. you'll get some respite.

we have drinks in 400m. so you're getting hot, cool down, take your drinks, and we've only got ten kilometres to the finish. good lad. keep fighting. yeah, nice. so i can see, automatically, that the psychological impact of that is huge. meanwhile, this lot are busy practising at speed. over 250 of these of trials take place ahead of the season. they make it look easy. but inevitably, it's not, as i can tell you firsthand. oh, no. so loud, and it's meant to be so quick. but i clearly wasn't. meanwhile, spence is already living life in the fast lane. thank you, lara, and by the way, this is how you really do it. laughter.

this year, mercedes has got its pit stop down to an incredible 1.85 seconds. now, that is quicker than it takes to say 1.85 seconds. it's a finely tuned operation that the engineers practice over and over in the days before each race. it's a bit of a ballet. the ergonomics are quite important. there are 20 odd people around the car to do a job in two seconds. you start banging into people you lose half a second, a second, then the strategists can't get their numbers right and you don't get the position you need. the human element to this ultrafast manoeuvre is accompanied by technology individually developed by each team. even the hydraulically powered wheel guns are a closely guarded secret. and i hear they're quite expensive.

they are expensive, and they have a life because they're under an enormous amount of pressure, so we're changing internal a great deal. do i hear about £30,000 each? i wouldn't know the exact cost, but that sounds quite low to me. we are going into mercedes‘ garage is now. keeping the pit crews safe is of utmost importance. these lights let the crew know if the cars have become electrified, stopping them from getting more than a nasty shock. at this year's world cup finals in russia, data is set to play a bigger role than ever before. like it or not, data is already an integral part of modern football. you can't watch a televised game without being bombarded by all kinds of statistics. for the first time, fifa are providing an all—in—one technical package allowing coaching staff and analysts to communicate throughout matches in real time.

the snappily titled electronic performance and tracking system, or epts, will provide data on player metrics, such as distances run, speed, and positional information. crucially, each of the 32 countries competing in the tournament will be provided with two tablets, one for a data analyst in the stands, who will be able to communicate with the second device user, on the bench, possibly a coach or an assistant manager. level one. lucy staniforth is captain of sunderland ladies and was shortlisted for the women's fa goal of the year. cheering. the game realism is spot—on. the defenders close to me, it was — i felt real pressure.

even just fine—tuning little skills. i think some of my touches went outside the box. i was not happy with that. so even that competitive edge, and sort of working on that, it's all good. another incredible development is being able to put yourself in any position in any game. 0bviously where raheem is, given that he's a fast player anyway, he has the advantage. as the ball‘s coming in the defender would have to turn their hips and try to clear it that way, i suppose. lucy is watching a real match that took place between man city and monaco. she can place herself in any position on the pitch, in the stands, on the roof, and even become the manager. right now i have a clear view of what went wrong in terms of the leftback‘s positioning. you see more detail on the players‘ position than you would watching match video? yeah, i think so. because you're on their level. and i think that there's so much value in actually appreciating what they — the picture that they saw.

and after a year of great sporting stories, you can see exactly how my ball skills have improved. it's the last minute of the world cup final and this penalty will win it. can he handle the pressure? here he goes. applause. right, off to japan now, one of the most exciting places that we travel to every year, well, because we don't know what we're going to find there. yes, robots. of course, robots, but not just robots. you know what it's like, you're stuck behind a car and you can't overtake because, well, you just can't see beyond that vehicle. well, this car might be able to help you.

it's fitted with a demonstration of a new technology called xtravue, and it means that you can see through the car ahead using its camera rather than yours. the vision at makers valeo is that the live stream from cameras on our cars will be available to everyone within a certain area. the forthcoming 56 cell network will make this tech more workable. imagine not having to guess what it could possibly be that's holding you up. lucky escape. now, another thing that may be of interest to japan's ageing population are these. they may look like normal glasses, but if i press the touch sensor on the side, you may have seen a little flash, and what that was was liquid crystals inside the glasses shifting orientation and changing the focus, meaning it's easier to see things close up, just like bifocals. now, the upside to these is you can then turn them off,

and it goes back to your regular prescription. this could be one of the standout technologies of ceatec this year, the ability to detect cancer through a urine sample. and hitachi are saying they can detect cancer in its early stages — and tell you what type it is. so it works for breast—cancer, lung cancer, for bowel cancer, and also for some childhood cancers, paediatric cancers. initial tests look very positive. they've only had a small sample at the moment, so more testing needs to be done. how long will this take to get into surgeries will be the question everybody‘s asking. such important development. injapan we're thinking one or two years to get through the formal stages of acceptance by the government. in other countries, like the united states, if hitachi decides to do some testing there, this could be available to the public within 3—4 months, certainly by the summer of next year. advances in mass spectrometry and machine learning has made the biomarkers in urine that change

with cancer more easy to detect. and, it's hoped, as reliable as a blood test. now, obviously, it needs a whole lab set up to do the testing at the moment, but the future, maybe five or ten years down the road, well, hitachi are already talking to a toilet manufacturer to put the testing element of this technology into toilets. so we could get a situation where every time we go for a pee we could get a result to test and check for any early stages of cancer. but then it got slightly more bizarre. now, something you might not expect to see at a tech show is a bonsai tree. or should i say a ‘bons—ai'. the tree, or maybe it's just a fancy pot, will automatically move towards light, let you know if needs water, and even offer wise words and advice to its owners. "i find out what the world needs,

then i go ahead and invent it." at least, that's what thomas edison said. look up and see how natural these skylights look. up until now, if we wanted a fake window, the fitting would contain either a blue light or blue glass or perspex. there is actually no blue light behind here. it's just two white leds each side, with suspended diffusers, mitsubishi described them as, in between to replicate the way that natural light comes through the atmosphere. they won't give us any more information, and they say it's about two to five years away before something like this could be installed in our homes, hospitals or even the underground, to give us a little bit of extra natural light. it's almost like i'm expecting to see outside. incidentally, that alarmingly realistic fake window trick turned

out to be one of the most watched tech stories on the whole of the bbc website in 2018, so clearly it shone a light on something. anyway, back in august, we sent nick kwek to france to meet a man with a mode of transport that we have been obsessed with over the last 30 years, but we have never had a chance to ride until now. and it's not this one. that's right, spen. i've popped down to provence to poke about in a frenchman's garage. we are in our workshop. it's where we do all our research and development. a formerjet ski world champion, franky zapata has been at the forefront of water—powered vehicles for decades. he has been beavering away over the years on several airborne inventions. i started with this prototype in 2011, then we built the real one. two years after, i got the idea of the hover board.

and then we got the idea to create the flyboard. it's self—balancing. you just press the trigger, and you fly. but recently, he has developed a penchant for rocket fuel. this bad boy has five jet engines packed tightly together, to blast franky off into the stratosphere. well, maybe not that high, but it can reach a top speed of 110 mph. you have a plan b for everything. you have plan a, plan b and plan c for the electronics, and you have plan a, plan b and plan cfor the engine. and you can lose an engine. so if one of these five engines blows, then... it's still flying. you can lose two engines, and it will still be flying.

the explosion will be contained by kevlar protection. the explosion? if it explodes. it can hold someone weighing 100 kilograms at 500 feet for six minutes. at $250,000 a pop, surely they will sell. it's not something we plan to sell. why not? if i tried this today, what would happen? with this one today, you would kill yourself. and, from tech from the movies to the tech in the movies, sir peterjackson marked the 100th anniversary of the end of the first world war by giving film from the era a new lease of life. they shall not grow old is a new documentary film about the first world war, directed by academy award winner sir peterjackson. using audio recorded in the 1960s and ‘70s, veterans of the western front recollect their wartime experiences. you knew what was going

on within your division. beyond that, you didn't have a clue. these stories are told over footage from the war, which has been painstakingly restored, colourised and converted into 3—d by jackson's team at wingnut films in new zealand. audio has been added in places, but the film develops entirely from the soldiers‘ perspective, in their own words. the stories are told in an imaginative and startling way. the film skips from the patriotic fervour of vetera ns‘ account of their enlistment to war to the brutal and shocking realities of day—to—day life and death in the trenches. some of these stories are told in a surprisingly matter—of—fact way. you didn‘t polish any buttons. you wore any uniform bits that you liked, and nobody worried. all that they were concerned with was that you were fit to fight. peterjackson and his team trawled through the 600 hours of audio and 100 hours of film footage provided by the imperial war

museum‘s archive in order to construct the film. vfx wizardry smooths the movement of the images, removing any jerky pictures. it‘s a very, very unusual method of storytelling. that struck me straightaway. it feels different to almost any war documentary i‘ve seen in the past. the brief that they gave me was — on the surface, it was very simple and very wide open. theyjust said you can do anything you want, but we would like you to use our archive film in a way that‘s unusual. so the first idea i had was i‘ll get them to send me some 2k scanned material, like three or four minutes, send it to new zealand where we have our visual effects department. i thought, how well can we restore this film? and that blew me away. we were able to restore it way better than i ever thought we could. 2018 was a big deal for us on click, too, as we took our live show outside the uk for the first time —

all the way to new delhi, in india. it was certainly one of the highlights of the year for me. are you well? and for him. but 2018 really does belong to the robot. there were these... cute, huh? ..these. .. this is fusion, my new robot backpack. fist bump. ..and this. david attenborough voice: deep in the heart of boston‘s jungle of cables, something stirs. it is a cheetah, and it‘s off for a prowl. we‘re starting to see walking robots

like this trotting out of labs around the world. now, the important skill here is not that they can walk a particular route autonomously. they‘re usually controlled manually, using games controllers. no, the amazing skill here is that they can walk and balance as competently as we can, even on the most unforgiving of terrain. ok, see, that‘s impressive. ok, that slipped, lost its balance, and regained its balance. that‘s the important thing. whoa! how hard is this to do? very, very hard. people might not know this, because we move our body very

easily, but we have to make sure that we have actually three times more neurons the muscles. so we have about 700 muscles, and we‘re trying to mimic that using only a motor. it‘s still pretty darn hard. how close are we to robots like this being of practical use, and what do we still need to get right? so i think we‘re pretty close in terms of mobility, like walking around, walking up stairs, and then turning. the harder challenge is still using arms. like, if i send this to power plants where some radioactive activity is going on, we don‘t know if it‘s real radioactivity, and to get there you have to open doors, and that‘s not a simple thing. you have to use your arms, and so on, and that‘s where the autonomous controls fail very, very easily. so how does the cheetah compare to the robots that seem to make all the headlines lately, those from the stable of boston dynamics?

well, ours is much younger. we‘ve been only doing this for six or seven years, so our software is very new. but our hardware is better. we‘re the first ones to use electronic motors to make these kinds of dynamic motors, and boston dynamics mostly use hydraulics, which is highly inefficient. i think, eventually, motor—based machines are going to be much more useful, safe and cheap and easy to maintain. but our electric motors are very different from the electric motors you can find in a factory. those electric motors cannot actually handle impact, cannot conserve energy. but ours are for landing, and jumping, and can do quite dynamic stuff. they certainly can, as demonstrated by this exclusive look at a previously unseen manoeuvre. you can‘t hear it, but our cameraman swore then.

that wasn‘t pretty. yes, but the thing is, it recovered and it stayed upright, and i know people that couldn‘t handle the recovery better than that. and this year, we‘re going to do it all over again. next week we will be in las vegas, and the world‘s biggest tech expo, ces, to kick off 2019 with a look at what‘s coming, from the car world to smarter homes and gadgets galore. we would love you to join us as we try and bring you the highlights of 2019 before they happen. so wish us luck, and we‘ll see you in vegas, baby. hello.

quiet but cold probably summarises the first week of january but this weekend we keep the quiet weather but it will be a little bit milder. a weak weather front trying to push into the far north—west but it is not going to make that much of an impression through this weekend. for the rest of saturday, it looks likely the best of the breaks in the cloud may be across parts of eastern scotland and the east of the pennines and north—east england but generally it is going to be cloudy and grey for many. cooler along the east, five or 6 degrees, further west highest values of between seven and nine. if you are heading to the fa cup

matches this afternoon let‘s hope the football is more exciting than the weather because it will be a cloudy and grey affair but it will be largely dry. into saturday night and sunday we will see this weather front pushing in from the far north—west, that will introduce showery outbreaks of rain through scotland and northern ireland eventually into the north of england but with all the cloud temperatures should hold up above freezing. if we get some breaks into the east we might see close to freezing but it is going to be a slightly less cold start to the day. on sunday the weak weather front, a band of cloud through northern england and north wales, behind it brighter conditions, the wind swinging to more of a north—westerly, fresher conditions pushing into scotland, between seven and nine, between eight and 11 further south. the real change arrives during monday as we see this area of low pressure bringing wet and windy weather. the isobars squeezing together on the southern flank of that low

as the winds swing back to a north—westerly, we will see gusts of wind gale force in places and some of the rain quite heavy moving through scotland, northern ireland and the north—west of england during the afternoon. gusts of winds, 50 to 60 mph to the far north of scotland, showers to come. a bright and breezy affair across much of the country, highest values between seven and 11. moving out of monday into tuesday and wednesday, across scotland and northern ireland it is going to turn colder again, good afternoon. the family of the man who was fatally stabbed on a train yesterday say he was an honourable man who would always help people in trouble. lee pomeroy, who was 51, was attacked in front of his teenage son just after they got on board a train in guildford in surrey. a man was arrested early this morning on suspicion of murder. a woman detained at the same time is being held on suspicion of assisting an offender. james waterhouse reports.
