sport now and for a full round up, from the bbc sport centre, here's katherine downes. britain's olympic bronze—medallist asha philip is through to the semi—finals of the 60—metres at the european indoor athletics championships in belgrade. philip, who was part of britain's 4 by 100—metre relay team in rio, finished first in her heat. the semis and final are tomorrow afternoon. richard kilty made a good start to the defence of his 60—metres title, winning his heat and finishing quickest overall. he'll be joined in this evening's semi—finals by theo etienne and andrew robertson, who also won their heats. in the long jump, lorraine ugen jumped a season's best to gain automatic qualification for tomorrow's final. 6.80 metres on herfirst jump was all she needed. she'll be joined in the final by jazmin sawyers. jody cundy produced a stunning ride to win the ca one—kilometre time trial at the para—cycling world championships in los angeles. cundy has never been

beaten in this event, it's his 13th world title in a career that also includes four paralympic gold medals on the track. it is getting harder as i am getting older, certainly the recovery afterwards. i do not know if it is the fact i am getting older or that we had only seven weeks to get ready for this. as i came across the line i looked at the crowd and i celebrated and i struggled to get up off the floor. i was pretty out of it for a long while. today's early kick—offs are just getting underway — in the premier league, it's manchester united against bournemouth — and no score yet but the game wayne rooney and luke shaw have both made a return to united's starting line—up. it's also goalless in the early

stages of the scottish cup quarter—final between rangers and hamilton academical. and after all the talk, some of it not pleasant, it is finally fight night. tony bellew is fighting for the first time as a heavyweight and he with a stone lighter and david haye. i am he with a stone lighter and david haye. iam ready he with a stone lighter and david haye. i am ready to perform. he is manufactured, he is not really a heavyweight. he is not in a million yea rs. heavyweight. he is not in a million years. aesthetics lee he looks fantastic, but when you get close to him he is trembling. he is trembling. he is not as confident and he does not believe the things he says. i looked at him and he was actually trembling. i was hoping he would look a little more physically impressive. i was hoping i would see some remnants of abdominal muscles or something, but he looked very

smooth. i have knocked out guys a lot bigger and stronger and more athletic than him, so i do not see what he can do other than get smashed pretty quickly. fighting talk, that is all the spot for now. goalless in those early kick—offs, now it is time for click. this week: smoking streets, burning fruit and keeping our cool as we go live in virtual reality. we are about to put a whole new spin on the world of mobiles. we are at the mobile world congress in barcelona, the big

show devoted to phones, tablets and all things mobile. we are a bit behind schedule, but we are going to get there. although, if we look a bit distracted it's because we are preparing for a rather audacious experiment. it is not that we are not interested in the floating displays, connected bus stops, flash cars, smart shoes or robot drummers, it is just that we are about to bash out something a lot more complicated. last year we filmed an entire programme in 360 degrees, allowing those watching in virtual reality to look around the fantastic locations simply by turning their heads or phones in whichever direction they please. in whichever direction they pleased. that is the power of 360, you feel like you have been teleported into the situation. we also have the ability to stream 360 live. so imagine that the next time

we send a robot to the moon, so imagine that the next time we send a robot to the moon, if it has a 360 camera on board, we can all put on a pair of goggles and actually feel like we are there as well. so that is what we doing today, getting ready to go live in 360, not to the moon admittedly, but to a place that is still a pretty strange landscape. so here we are at the massive mobile world congress. enormous halls of madness and noise as everyone tries to launch their products with maximum pizzazz and volume. but this event is notjust about mobiles, virtual reality is everywhere. since you can use a phone as a vr headset, many companies have opted to up the excitement by strapping people in and hurling them about. yes, vr can be totally immersive if you have your own 360 chair. i don't even want to think what kind

of experience this chap is having. going live in 360 is less about the headsetm, it's more about the camera equipment you can and cannot use. you are currently watching me through a nokia professional 360 camera with a professional price tag to boot, about 16,000 us dollars, but it is a beautiful looking thing. it has eight lenses so you can see in all directions, but it can also shoot in 3—d because the combination of lenses allows it to process a stereoscopic view. what is really weird is it has this enormous battery pack which you think would be in shot, but this thing has a blind spot to about here. so they have this almost 360 view and stretch it around. modern 360 cameras will stitch the scene together themselves

in real time, automatically wrapping the weird warped video into a sphere around your head and that is what enables them to go live. if you wanted to stream the full 360 view, you are going to need some extra kit. two dedicated hardware boxes and an upload internet speed of at least 30mb per second. in a trade show like this, we are not that lucky. i think we have to accept that it's early days, that to get really high—quality, stereoscopic video, so you can really look around and feel a sense of depth and feel that you are there, it is going to take a while. there are bandwidth problems and just having equipment that can transmit that amount of data so that when you look, the picture gets rendered according to exactly where you are looking. it will take a while, but we are starting. we are going to be doing two lives

in 360, testing two different cameras and this is no mean feat because as with last year's 360 show, we are coming to this before the manufacturers have made bespoke equipment. to get good pictures, good sound and decent interaction with the audience, we have to hack together various bits of kit and hope no one trips over. my microphone goes into a transmitter which goes into a receiver which goes into a box which plugs into another box and we've got half a mile of ethernet cable, which is going to a network access point hidden in the garden! the first 360 camera is the 0rah ill, four lenses which between them can shoot the 360 video in ultrahigh def, although this is the resolution def

ak, although this is the resolution of the entire 360 shot. the viewer only sees a part of this as they look around the scene. at the moment, it is not showing us anything we want. they are seeing us in london, we are a bit blurry but it will get better. it was our very first attempt so things were bumpy and rough around the edges. we were supposed to go out minus 15 minutes ago. where did spencer go? it is my fault. we are going live now. take one. that said, it seemed to hang together and viewers on our youtube 360 channel got to find out a bit more about a car planning to go at 1,000 miles per hour. there are three engines? yes, it has a gas turbine from the typhoon eurofighter and it has two nanojets. rockets? rockets effectively. and you need all three of them? yes.

to get to 1000 miles an hour. yes, so the gas turbine is for your below 800 mph manoeuvres and then the rockets fire you up to give you the kick to over a thousand. streaming such a high—quality picture takes a lot of data hence we had to use a fat, wired internet connection of about 10 mb a second, but for our second attempt, we went commando. this ricoh camera is the one we used to shoot the 360 helicopter scene last year. it is a small hand—held stick with two fish eye lenses. its full view is only 2k, so the part you see in virtual reality is much lower resolution. but that does mean it is possible to stream video live over the mobile network. which is what we did, in style, with a drone. giving a taste of what it is so like to be so close to a drone you might lose a limb.

very soon ricoh is releasing the theta r with a few upgrades including more connectors, expandable storage and it will do the stitching in the camera itself rather than needing a computer to deal with the ground work. for now, though, we were pretty happy with our little experiment and very soon there will almost certainly be more fully integrated kit to let us go live in 360 with much less bother. when we went up to the hadron collider to film this is in 360, we used six go pros strapped together to film the entire scene. we then had to stitch that footage together manually using a powerful computer and software and many, many hours. since then go pro has released the 0mni which is a case in which 60 go pros fit. in which six go pros fit. it has one remote start for all six cameras, which is good,

and it also comes with a box that does all this stitching. and in a couple of months' time, go pro says it will release an update which allows you to do that live. and if you want to create your own little 360 videos, this tiny camera plugs into your android phone. the videos are not live, but the stitching is quick and you can share it easily on your social network. enough 360, let's see some phones. now, a couple of years ago we got to play with a sony camera which could shoot video in super slow motion and we discovered that everything looks cool when it is filmed a0 times slower. well, almost everything. so it is no real surprise that that technology has now been shrunk down and down and has made its way into a phone. three, two, one, go. this is the new sony xperia x2 premium and it can film at 960 frames per second,

which is great news for glitter boarders everywhere. to do this sony has had to embed some superfast storage in the image processor sensor itself. the problem is because there is only so much space you are limited to an extremely short burst of slomo every few seconds within your video. it's all right when you want to catch something in super slow motion that is going on for a long time like this, but when you want to catch something that only happens once, it is quite nerve—racking. case in point, setting fire to orange zest which i didn't even know was a thing. three, two, one, go. i was too premature that time.

and that is the problem, the burst of super slowmo is only 0.182 seconds, that is less than a fifth of a second, so you have to be spot on with timing. me for the most part, i was a bit too trigger—happy. but when you do get it, flaming oranges! it is worth bearing in mind that sony actually makes the camera parts for many other brands of mobile phones, so if this super slomo catches on, we could well see it in other phones for too long. phones before too long. what else is hot at this year's mwc. here is stephen beckett with a round—up. incredibly, at a convention with some of the biggest phone manufacturers hawking their newest and shiniest devices this is the phone everybody is talking about. finnish start—up hmd global has

resurrected a scintillating piece of nostalgia with a reboot of its nokia 3310. do you remember that? hmd licensed the nokia phone range at the end of 2016. it includes an indestructible handset with a seemingly infinite battery life and has been given a new lease of life with modern curves, jazzy colours and of course a re—versioning of snake. the blackberry has also gone back to basics with their new phone the key1. it has a physical gesture sensitive keyboard that hides a fingerprint scanner under the space—bar. and that is not the only slice of nostalgia here at mwc. samsung is getting in on the action with this classic norris pencil, although i would not try and sharpen this one because it has got quite a lot of digital gubbins at the end allowing you to do things like this. google would much rather you talk to your devices rather than read to them. it has announced its personal assistant. google home will finally be available for sale outside the us, and by may in the uk.

and in another new attempt to dominate the ai market the company also said it will roll out its voice activated digital assistant to all android phones running marshmallow and nougat. until now it has only been available on google's own pixar phones. that is apart from huawei. those are set to use amazon's alexei instead. amazon's alexa instead. the upcoming moto z will get its assistant parts through a snap through a snap—on back which they are calling a moto mod. others are ditching customisation. lg launched its new flagship phone without a modular capability of its previous model. the company says customers do not fancy forking out for extra parts. the lg g six also knocks the traditional aspect ratio out of the park. the screen is 18 x 9, in otherwords twice as tall as it is wide. smartphones have traditionally been 16 x 9. and it would not be much of an nwc

round—up without at least one mention of the words 5g. even though no official 5g standard even exists yet, that has not stopped everyone here from snapping the term all over their stands. nowhere more so than here with a bold claim of creating the world's first gigabit phone. this is sucking up data around 50 times faster than the speed you would get on your 4g phone in your pocket. we are not allowed to touch or use these phones and that could have something to do with all these cables poking out of the back. it could be some time yet before you get your hands on these sorts of speeds. over the past few years the air we breathe in our cities has become a big issue. air pollution is an invisible killer and it is something that many people from politicians to tech companies feel needs urgent attention. but what to do? well, all next week the bbc is going to be looking at the issue and possible solutions and ahead of that we have been checking out some of the gadgets that might help us to track the pollution around us, so you can choose what

to do with that data. we have been finding out more. it only took five days this year for london to reach its yearly air—pollution allowance. people were warned to reduce outdoor physical exercise as levels soared beyond those in beijing, a place where scenes like this are not unusual. and with limits being exceeded in germany, france, italy, spain, as well as other cities across the uk, never before have we been so aware of the air we breathe. yet if there are better or worse days, or a better route that you could take, then could using a personal air—quality tracker help you make better decisions about what to do when? first of all, it depends how accurate they are and that is something i am on a mission to find out about. the makers of some of these devices

say they have gone through extensive testing over a long period. whilst our spot checks today are just a snapshot, i am curious to find out how they measure up. so to carry out our first experiment i have come to this central london mews and i have enlisted the help of the university of birmingham who, for fairness of the experiment, have brought along this, which is going to take some pretty serious recordings of air—quality along with my four devices here to see how they do. the atmo tube can be attached to a bag to track organic compounds known as vocs as well as carbon monoxide. the cleanspace tag was released last year and tracks carbon monoxide. it connects to the company's app adding a personal and crowd sourcing element to the official data it already displays. the i—blades smartphone case amidst its other functions has an air quality sensor tracking vocs.

and this working prototype, flow by plume, works alongside the already popular plume air report app. it currently tracks mitogen oxide and vocs, eventually aiming to add particle matter and ozone as well. they are all suitable for outdoor as well as indoor monitoring. so, i have given the devices five minutes to do their thing, but right now this is a bit of a sea of numbers, but luckily i have found a man who knows what all of this means. i am joined here by professor roy harrison from the university of birmingham. what is going on here? we are getting rather different readings on them, but they should all be giving us very much the same impression of the pollution. and this is where the fun begins. there is the atmo tube. it is giving us 0.22 ppm, which is telling us is good air quality.

93 out of 100. it is telling us things are pretty clean and in this environment that would be a pollutant mostly coming from traffic. if you go indoors, there are other sources. 0k, comparing that to your readings, do they seem like they are on track? i would say our reading is a different pollutant, but it is telling us it is rather more polluted than this than this 93 out of 100. i would not call the air quality good, i would call it average. we have got the cleanspace device next with their tag. this is reading carbon monoxide. it is giving us concentrations that appear to be a little above 1.5ppm, which i would say is very consistent with what we are seeing in the nitrogen dioxide. it is giving us a moderate level of traffic pollution as we might expect. i think that in a sense is a more predictable sensor than the ones depending on volatile organic compounds because that is a very big range of substances

and the sensitivity will not be the same for every compound. now the next device we are looking at is the i—blades phone case. i noticed this one set a baseline for whenever you open the app. so when we opened it here on this street it is calling this streak zero, which seems a bit of a funny way to work, doesn't it? i think it is, yes. so, ideally it needs to be zero in the very clean atmosphere, but if you do not have an independent monitor, how do you know where that clean atmosphere is? i think we have a bit of a difficulty with this one. our final device that we have got here is flow by plume. this is the prototype, the finished version will look similar. it syncs up to an app that does not actually give numbers. what do you make of that for a start? well, i understand the sensor is responding to nitrogen dioxide and volatile organic compounds, so we might expect it to be correlating with our device in the car. this is telling us that the pollution level is high and i understand that that is based onjudgments against

health—based standards from the world health organisation. i find it a little surprising because i wouldn't regard the levels here as high, certainly not a particular health risk for example. for the second part of our experiment we have come to a somewhat busy street, baker street, the home of sherlock holmes, where our investigations shall continue, professor. i can see the readings have been changing. what do you make of things here? it is a busy street and our reference analyser in the car is showing concentrations about double those we were reading in the mews, or even three times higher at times. the atmo tube registers a rise in pollution but still calls the quality good. the cleanspace tag reacted appropriately, the i—blades case

rose from zero and flow by plume still simply says high. there is an argument from some that by tracking this data and taking control ourselves we are diminishing the government's responsibility to improve the situation, but what does our scientist walk away from our day's activity thinking? they are very variable in their performance. one could try and use them to judge which routes were the best ones if you were walking to work for example, but that would not be a simple matter because the pollution levels change from day to day based on the weather, so you would need to do the different routes many times in order to get a representative measure of what the actual pollution levels were. but i suspect your answer would be no better nowjust looking but i suspect your answer would be no better than just looking at the traffic and saying, well, this is a very quiet road, why don't i use this one?

so it seems to find my perfect running route i need to either run a lot with the devices or keep my eyes open without. that was lara and a big source of air pollution in the developing world is produced by the burning of kerosene. it is also very dangerous and can cause house fires. obviously it would be preferable to move to solar power, but a rig like this costs $200, something that many families cannot make as a single lump sum. this company is suggesting renting a solar system like this with a panel and all this kit to families in return for micro—payments, about 50 cents a day, which they can make over the mobile network. once they pay for the price of the equipment they get to keep it. if they stop making payments at any point, the company can contact a box like this over the mobile network and switch it off remotely. a similar scheme is being piloted with gas in tanzania to try to move people away from cooking with charcoal.

again the barriers to entry mean by an entire gas mean buying an entire gas canister is too expensive, but this smart meter system allows micro—payments over mobiles, which allows small amounts of gas to be released. you could of course remove the meter you might think, but if you do, it sends an alert to the scheme's administrators. here is something else that impressed us here at nwc, hence the impressed look on all our faces in this picture. this is a phone that was released a couple of months ago that let's you take 3—d photos with the stereo lenses on the back and then you can view the photos in 3—d without glasses on the screen because it has a lenticular display, which means your left eye only gets left eye information and your right eye only gets right eye information. if you hold it right at the sweet spot you get a 3—d picture. if you hold it outside the sweet

spot everything goes crazy. i would not recommend that. anyway, that is it for click at the mobile world congress in barcelona. i hope you have enjoyed it. feel free to let us know what you thought about our 360 live. about our 360 lives. be kind, but be honest as well. thank you for watching, see you soon. all sorts of weather for you, spain and settled. if you do not see the sunshine today, you will see it

tomorrow. central and eastern parts of england look mostly dry, further west heavy showers and blustery winds, gale force gusts at times. temperatures only six or seven in the north, 12 or 13 in the south. scotla nd the north, 12 or 13 in the south. scotland will see that rain and hills no pushing northwards overnight. elsewhere further showers 01’ overnight. elsewhere further showers or outbreaks of more persistent rain moving into night. on sunday that rain is sitting across much of wales southern and central parts of england. it pushes itself gradually further eastwards, so many parts of wales seeing that rain, perhaps some snow in the pennines, but an improved state for scotland and northern ireland. good afternoon. sinn fein are celebrating their best—ever showing in elections to the northern ireland assembly. with all the votes counted, they've won 27 seats, just one behind the democratic unionist party. sinn fein‘s president, gerry adams,

has described the result as "an end to the old status quo". the two parties now have three weeks to try to agree a new power—sharing coalition. from belfast, chris buckler reports.
