hello, this is bbc news. we'll be taking a look at tomorrow morning's papers in a moment. first, the headlines. the death toll from the coronavirus rises to 41,

with authorities in china struggling to contain the outbreak, as millions travel for the lunar new year. benita mehra, a newly—appointed member of the grenfell tower inquiry panel, resigns after being linked to the charitable arm of the firm which supplied the tower block's cladding. donald trump's lawyers have begun their defence of the president in his impeachment trial in the senate. they say he's done nothing wrong. the search for survivors continues after a powerful earthquake hit turkey. at least 29 people have been killed and more than 1,200 injured. hello and welcome to our look ahead to what the the papers will be bringing us tomorrow. with me are martin lipton, who's the chief sports reporter

for the sun, and the broadcaster and psychotherapist, lucy beresford. many of tomorrow's front pages are already in. the sunday telegraph leads with a story about the firm behind the high—speed rail project. so too does the observer — they say scrapping hs2 would cost £12 billion in write—offs and compensation. the mail on sunday claims the government has evacuation plans for britons stuck in the coronavirus hit city of wuhan in china. the sunday people has a special investigation into dolphin poaching. the sunday mirror interviews one of the victims of multiple sex offender reynhard sinaga. and the sunday express devotes its front page to borisjohnson‘s plans post—brexit britain. so, a mixed bag there, various

stories breaking through but of course, the story, martin, that we must start with, the whole situation with coronavirus and the telegraph has a story all about the fact that britons may be getting the opportunity to leave, tell us more. this is the second leave, i think it isa this is the second leave, i think it is a significant story. the foreign officers said it was preparing to advise all citizens to leave wuhan. vulnerable people should evacuate the area. apparently, those who are in the city, it says here, 300, the mail says 200, no one seems to be sure, they are accusing the foreign 0ffice sure, they are accusing the foreign office of abandoning them. the french apparently have 500 citizens being offered a coach service, that will be a fun bus, won't it? all aboard with that. last night, the

foreign and commonwealth office faced a growing backlash over its response and they've got some quotes there from people moaning because they are rather scared, i think, at they are rather scared, i think, at the moment. about the lack of help. it seems to be that the british government have been a bit slow. the problem is, the city itself and the whole district is a lockdown and thatis whole district is a lockdown and that is very preventative because we don't want people moving around and spreading it. so, presumably, the foreign office thought to themselves it would be better if we kept people that because otherwise if they are infected, they will be brought back to the uk and that might have repercussions for our health system here. they have gone back on that advice, as martin says, there are people who have been quoted as saying, we have been looking at other nationals in a district and they seem to be being helped by their embassies. that hasn't been their embassies. that hasn't been the case here. ijust don't see how it is actually going to help to bring them back because if they are

infected, that is going to put more ofa strain infected, that is going to put more of a strain on our resources. interesting. some of it seems to be about practical moves and whether they should be leaving, but one of they should be leaving, but one of the criticisms hear from somebody quoted to is that says, we have seen no real attempt on the british embassy or foreign office to reach out and offer us some support. maybe it isa out and offer us some support. maybe it is a communication issue. maybe people aren't sure what is going on. if you are unable to get in, the city is on lockdown, there is a great deal you can do, you could ring around and say, sit tight, there is nothing we can do at the moment. nobody knows how they relate this illness is going to be, they don't actually know... it has appeared to circumnavigate the globe but nobody is really sure. it is very possible that sitting tight and waiting ones that will be very frustrating for the people who are there, they will get the most incredible cabin fever being stuck at home and maybe not even able to go to supermarkets and may be food and supplies but even the

supermarkets so they might get to a point where actually the whole city is kind of under siege. it is so difficult because it is a long way away, it is a big city about which i suspect very few people have any knowledge, i knew next to nothing. it's extraordinary. given it is a massive city. i read there are 100 cities in china with more than a million population which is a terrifying number. mind blowing. it's a big country. what we do have isa it's a big country. what we do have is a situation which is evolving rapidly and globally as well and i think that all governments across the world are going to be trying to see what they can do, whether they need to react more swiftly, what precautions have to be put in place. we had the avian flu a couple of yea rs we had the avian flu a couple of years ago, we have obviously had outbreaks of difficult, dangerous flows which have taken lives

across. . . flows which have taken lives across... it is interesting that you could have an illness like this, it is really capturing the imagination but far more people die every single year of malaria and other fevers, some very serious illnesses that are still in existence, they take lives every single year but sadly this captures the imagination. because it is no —— new, and because of the thing about the markets and the bats or whatever it may have come from. it feels like something like anew and therefore it is, i hate to use the word, but it is a sexy story. we we re the word, but it is a sexy story. we were doing a headline earlier which was world war flu, we do like to go to town, but obviously it is frightening for p. lucy, the mail on sunday, in contrast to telegraph with the same the british should leave under their own steam say there is an alleged plan to get the brits out, according to the foreign secretary. that's right, dominic rob

claims they are drawing up evacuation plans as the infections accelerates. if the market was closed down towards the end of last year and there was a move afoot to really contain it, why would the plan now bait to spread people more widely. itjust plan now bait to spread people more widely. it just seems to plan now bait to spread people more widely. itjust seems to be counterintuitive. i guess in all of these scenarios, i guess there is a balance of helping people feeling supported and playing to public opinion about worry and illness. there is no right solution at this stage because whatever you do, you are going to be damned by someone. it is really tough. also, i think governments will want to be seen, all governments will want to be seen to be at least as proactive as they can be in a situation which is, as we said, evolving so swiftly, and whether people are justifiably scared because of fear is the biggest driver of most people. what do we do? who is looking after us? where do i go? what has been

fantastic is compared to sars and mers, a couple of these epidemics are a couple of years ago, the world has changed, in particular in terms of social media, you can get so much more information out there, you can actually lockdown a city of 11 million people because every wedding is the information really quickly. and allah takes us back to the berlin airlift, it has very different connotations, feels very old—fashioned, but i still maintain, what do i know? but i still think sit tight... get on the bus with the french. do you want to be the driver of that bus? as someone said to you, i've got a job for you, you've got to get a bus into wuhan and take people back? you might end up with extra passengers. i'm taking you to a different story now, lucy, back on the sunday telegraph, this is their main story but we had to do the virus, but this is all about hs2 and words like con and cover—up, it is a

strong story here about the rising gusts. yes, i mean, with a report that was leaked a few days last week which did reveal that the cost had excavated to over 100 billion, one of the countries that is involved in this and has been supporting the government in trying to work out whether it is a viable proposition, they are now, it is alleged that they are now, it is alleged that they have actually been masking the true cost of it, that actually, ministers have not been kept informed over the last year or so, and it is really interesting because borisjohnson has and it is really interesting because boris johnson has announced and it is really interesting because borisjohnson has announced he probably will make some kind of announcement about it in the next week. this is a man who has really widely spoken about wanting to be the infrastructure prime minister so this is the classic kind of project that he would probably really want to back but what other benefits? is it actually going to be worth the and the report, it has also been

alleged, failed to take into account how much money it was going to cost for example to buy up lots of homes and properties and land that would have been required to actually make this project a success. on the flip you've got members of the local governments, you've got andy street in birmingham, andy burnham up in manchester, they have that written to the government saying, this will be praying for us, please don't rely, don't betray us because you promised you would do this. really, burris is walking a tightrope here. what do you make of this, martin? there is pressure from both sides. there is pressure from both sides. the cuts have become astronomical but there has always been this push from government to say we need to get a better infrastructure in the north. i am absolutely stunned to discover that a major building project is going to go over budget. whoever would have dreamt that would happen? there is over budget and there is over budget. only double.

is it justifiable? a there is over budget. only double. is itjustifiable? a question i cannot answer, to spend a hundred billion pounds to take half an hour of the journey. it is notjust at that time, it is that the extra capacity. the argument is should that money be spent on proper west east communications between the big cities in the north, but at the moment we've got this huge hole in the middle of birmingham, where the main station is going to be, and at the moment there seems to be a lot of hole filling out a lot of building going on there. of hole filling out a lot of building going on therem of hole filling out a lot of building going on there. it is funny you should say that because a lot of mps who are anti—hs with northern constituencies say we wouldn't be affected by this at all but somehow we are still paying for it, we would rather you build our potholes, improved our bus services, though more local, and actually it isn't just this one product. is that the situation at this government is pushing, it is supposed to be the

big push on and off. if you are saying you need to connect the north and the south and make them —— the north more economically viable, if you cut down a major infrastructure project which is about making the north more economically viable and more successful and therefore allowing people to expand, it doesn't sound great. in theory, the idea is they will expand northwards but a lot of people are worried it willjust but a lot of people are worried it will just accelerate but a lot of people are worried it willjust accelerate people pulling back down towards london. lucy, in the observer, contrasting story because of the one hand the telegraph as saying soaring costs and pressure to dig chick but the observer is sane if you scrap it, there will be a £12 billion anywhere. 12 billion is an awful lot of money and you could a lot of things with it, however, if your bill is over 108 billion, then 12 billion is pretty much nothing, that is loose change, again it is either obscenely expensive, the question is

is it actually going to be seen as a betrayal of the north? if boris johnson pulled out of this. or is it actually worth saying, yes, it is a sunk cost, we have already spent that money, maybe any infrastructure project app—macro to be able to not do an infrastructure project... we would never have had the channel tunnel of the victoria line. every single... crossrail. the way the bill that looks and sucks the air in through his teeth. this is interesting, and the observer, they we re interesting, and the observer, they were analysing what these write—off costs are going to be, martin. three to £4 billion immediately, 9 billion has already been set aside. itjust tells you that there is no easy solution here, you are damned if you do, damned if you don't. but this has been a project that has been ongoing for a decade now, hasn't it?

it was one of the last acts of the previous labour government. in the brown government. we have had three prime minister since then and i have all been nominally committed to it. no one wants to pull the plug give it the full go—ahead. no one wants to pull the plug give it the full go-ahead. whoever says no will be remembered as the person who ended it. i don't how you win, andi who ended it. i don't how you win, and i think you can win. and the problem is if you cancel it, what do you do with their money? a lot of the other projects you would love to start, they are probably not ready, they are not, at forest likes to say, they are not as unready. we we re say, they are not as unready. we were going to talk about epidurals and the fact that women hospitals aren't getting them as often as they would like but we are saving at the next hours. that's it for the papers this hour. martin and lucy will be back at 11.30pm for another look at the papers. don't forget you can see the front pages of the papers online on the bbc news website. and if you miss the programme any evening you can watch it later on bbc iplayer.

next, it is time for click. three, two, one, zero. getting into space is an expensive, dangerous, highly complicated business, where hundreds of thousands of precision—made parts all have to work together perfectly. if they don't. .. but as the race back to space hots up, commercial ventures

are looking for simpler, cheaper, quicker alternatives to building spacecraft. and here in la, ifound a startup trying to solve all of those problems in the unlikeliest of ways — by 3d printing rockets. this is relativity space. existing rocket bits are not 3d printed. what is the advantage of 3d printing? a lot of it, from our perspective, is flexibility. traditionally, factories are made of tonnes of fixed tooling. it's then very expensive, very hard to change, then where you have to retooling factory in order to make a new product or even change a product slightly. for us, we can change all of that in software. so it's digitising the manufacturing process and providing flexibility, where, if you push new code to the printers and the hardware on the factory floor, you can actually make an entirely different product without changing anything in hardware. after a stint at spacex,

jordan formed relativity space with his friend and ex—blue origin engineer tim ellis. the two twentysomethings realised that 3d printing could help in several ways. because it builds up objects layer by layer, it can produce complicated structures out ofjust one part. also, much of the manufacturing can be done autonomously, which leads to a rather remarkable aim. the team wants to send robots to mars which can then build rockets on the surface. and that means that the astronauts who eventually land there will have a way of getting home. it's both better, cheaper, faster. it's going to actually evolve more quickly than other technologies and we'll launch factories to mars, actually build things like housing, spare parts and infrastructure, and eventually leading up to printing the first rockets.

why has no—one done this before? no—one's had a printer big enough to print something that big. and a lot of the challenge we had as a company was making printers big enough to make entire rockets within them. this is what the printing process looks like close up. a robot arm weaves backwards and forwards to lay down a thick layer of special high—strength aluminium alloy. so this is it, the world's largest metal 3d printer. it's currently printing the top of the first stage of the rocket, or the first bit that burns its fuel and is then jettisoned. this is the top of that. and if you look really closely, you can see that it's very slowly rotating. it takes about an hour to go all the way around at the moment, and that means that the robot arm — with all the hot stuff and liquid metal stuff — can stay relatively still as it weaves each layer.

and that means you get a lot more precision. the whole thing will take about ten to 12 days to print. i can wait. i don't know about you. and why have one giant 3d printer when you can have several running in parallel? they're basically off the shelf robot arms, all arc welding different rocket stages that, when put together, can stand 30 metres high. in its first five years, relativity space has already secured contracts with nasa and others. and next year, it hopes to make its first launch from cape canaveral in florida after becoming only the fourth commercial company to secure a launch there alongside the united launch alliance, blue origin and its la compatriots spacex. and, sometime after that, mars beckons — and the promise that anyone who journeys to the red planet is not making a one—way trip after all.

hello and welcome to the week in tech. it was the week saudi arabia was accused of hacking the phone of amazon's billionaire founderjeff bezos. crown prince mohammad bin salman is alleged to have sent an encrypted video file via whatsapp, which saudi arabia denies. it was revealed that the introduction of gdpr in 2018, the eu has imposed 114 million euros in fines, with regulators in france, germany and austria handing out the biggest fines so far. is it a bird? is it a plane? yes and no. it's a pigeon bot. researchers at stanford university have built a robot bird using real pigeon feathers. the team believe their findings could inspire future aircraft wing design. quite the coup! how would you feel about sharing a ride in a driverless car without a steering wheel? the origin, made by general motors'

own crews, is also missing pedals and a rear—view mirror. its developers, which also include honda, hope that multiple—occupancy electric vehicles will reduce emissions, accidents and congestion. and finally, spending too much time on your smartphone? google suggests popping it in an envelope. google envelope is an app used in conjunction with a paper cover you can print out at home. the combo can dumb down your device so it can only make and receive calls or transform it into a photo and video camera with no screen, although it only currently works on the pixel 3a. will it work? answer‘s on a postcard. now, much earlier than normal, we find ourselves in oscars season. it's the academy awards in a few weeks' time. and between now and then, we are going to be meeting the people behind the most innovative developments

in the movies that are up for the awards. and we start with this monster hit. whatever it takes. this show had so many challenges, i think, because it's such a pinnacle of the marvel universe. excuse me, mr hulk? yes. can we get a photo? smart hulk in particular was a real challenge because we were taking our facial animation to places we hadn't been. and to get that level of performance was definitely a real challenge. so, when they were shooting, they shot with mark ruffalo in place as smart hulk. he would wear a motion capture suit and also some head—mounted cameras to capture his facial performance. so that meant, once we got the shots turned over to us, we had a good amount of reference to get started with. although we had this amazing performance for mark, if you put 100% mark onto smart hulk, it wouldn't look like smart hulk. it would look like mark ruffalo pretending to be smart hulk. so there's some amount of refinement we had to do to find that performance,

to find the character. we used some machine learning techniques to enable us to capture his performance very quickly off of that footage and put it onto our initial model. we tried to get that really finessed human performance, which is probably one of the hardest things to do in cg. something else we took from our machine learning information was some of the really small micro movements. although we did most of it had animation, it was very important we could take these tiny little micro movements, like just very small bits of eyebrow movement, cheek movements, just really subtle so you can feed it back over the top of the hand animation to really capture the performance. the biggest problem, i think, we faced was actually the quantum suits that the avengers wear because, when they shot it — way back before infinity war — there was no design for the suits. so nobody was wearing a suit and no suit was ever built. so we had to work out several things. one is how we were going to place everybody‘s costumes? because they were being shot in whatever costume the avenger happen to usually wear. in some cases, that created

quite a few problems. some of the costumes that they were wearing have very high collars, so the newer suits that they would've been wearing wouldn't be covering all of that costume. so there'd be bits of their next would be visible, which we have to recreate either in cg or in painting it back. and in some shots... the establishing shot when they first walked into the hangar altogether was actually shot with stand—ins. they've done the lines... we ended up replacing their heads as well. sometimes using a double, sometimes using pieces of plate from our shots. we could find a nice side view and stick that in because it was quite wide. but the other thing to bear in mind is in these shots, because we had to integrate the lighting on the suits into the plate as well, we built a full cg hangar — which we needed anyway... there was a green screen behind them, where the windows are. and even though the green screen was outside the windows, we had to replace all the windows simply because we needed the reflections of what we are

putting into the building anyway. so by the end of the day, the only thing that's actually left in those shots from what was filmed, is their heads and part of the ceiling. so we replaced the hangar as well. so, actually there was one shot in particularfor ant—man right at the beginning of the time travel testing. ant—man introduces the quantum van. that shot was originally in a different sequence, shot in a different part of the hangar, so the background was all wrong. so we had to take that and completely change it and change the environment, change the van. and then it was like, "oh, he's also in the wrong costume." so we ended up replacing his costume as well to put him into the ant—man quantum suit that he was wearing for the rest of the sequence. so that was another sort of last—minute, single—shot design of a costume to match what it was exactly like in the rest of the shots. people like to see the big flashy effects. but the satisfaction comes a lot of the time from doing work, good work, that nobody realises is there. and we'll look at the secrets behind another oscar nominee next week.

now, this is the end of the short version of click for this week. the full—length version is available to watch on iplayer right now. and we'll be back in la in a few weeks' time for the academy awards. in the meantime, follow us on social media. we live on youtube, facebook, instagram and twitter at... thanks for watching and we'll see you soon. hello, there. some rain on the way, i haven't said that for a while, high pressure has kept things quiet for the last week or so but low pressures about a comeback and the

first sign of that is this rain moving in across the western side of the uk overnight, and ahead of that still plenty of cloud, patchy light rain or drizzle, the breeze is now picking up across the uk and those temperatures are not very down to far overnight. some first to start sunday, but some rain quickly clear in northern ireland, pushing through scotland, on through wales and england as we go through the day. it brightens up, especially in northern ireland and scotland, some showers turning wintry in the hills, especially in scotland. temperatures are dropping behind a clearance of the rain and so the wind and those temperatures falling away just making for that chilly feel two things. that is how we go into the new weight, colder, sunny at times, showers, and cold enough for those to be wintry in places, too, particularly across northern hills. that's your forecast.

this is bbc news. the headlines at 11. the death toll from the coronavirus rises to 41 — with authorities in china struggling to contain the outbreak, as millions travel for the lunar new year. the uk foreign office has updated its guidance to advise against all travel to wuhan city, and said "if you are in this area and are able to leave, you should do so" benita mehra, a newly—appointed member of the grenfell tower inquiry panel, resigns after being linked to the charitable arm of the firm which supplied the tower block's cladding. donald trump's lawyers have begun their defence of the president in his impeachment trial in the senate —
