to use their platform. democratic party members of the us house of representatives have circulated the draft of a new impeachment resolution against president trump. it accuses the outgoing president of high crimes and misdemeanours, including incitement of an insurrection. a white house spokesperson said impeaching the president would only further divide the country. the uk has recorded its highest daily death toll since the pandemic began — more than 13 hundred deaths were reported. and a major incident has been declared in london as hospitals across the uk struggle to cope. all visitors to the uk from next week will have to have proof of a negative covid test before they're allowed to travel. anyone arriving by air, rail orsea — including uk nationals — will have to take a test up to 72 hours before departure, and people arriving

from countries that aren't on the travel corridor list will still have to quarantine for up to 10 days once they arrive. our transport correspondent caroline davies reports. until today's announcement, the uk has not required anyone arriving in the country to show that they've recently tested negative for the coronavirus, but things are about to change. international arrivals, including uk nationals travelling to the uk, will need to show that they have a negative covid—19 test, taken up to 72 hours before they travel. it applies to everyone arriving by boat, plane or train, but not to hauliers or children under 11, and it won't apply to anyone travelling within the uk or ireland. the government have said tests will be needed from next week but haven't set an exact date, and they haven't specified a particular sort of test. there can be different types of tests, so viewers will have heard of pcr tests, perhaps, but there are also lateral flow tests and lamp tests. the important thing is, it's up to certain specification, and then people take that test, and as long as it is negative, then they can fly, but they can't board the plane,

for example, without having that negative test. some other countries already have strict measures in place. raphael recently returned to south korea. it took 2a hours of testing and paperwork before he was allowed home to quarantine. he said it was very different when he flew to the uk. the process was completely opposite. there were no checks. there is no temperature check. there is no screening. there was no social distancing. many people were not wearing masks. travelling through southeast asia, neil has had 11 tests. we surprised? i was, it asia, neil has had 11 tests. we surprised? iwas, it was asia, neil has had 11 tests. we surprised? i was, it was a ridiculous scenario to be in. transiting ridiculous scenario to be in. tra nsiting through two countries. and then arriving in

the uk and getting the all clear for the uk and getting the all clearfor me, it'sjust the uk and getting the all clear for me, it's just an absolute nonsense. even with a negative test, arrivals from countries not on the travel corridor list will still have to quarantine. those in the industry who have been calling for testing hope that eventually it can be used instead of quarantine, but some airlines are concerned that passengers getting positive tests could destroy their business. many countries around the world are brought in predeparture testing. but it can be very confusing for passengers. you leave the risk that they'll all cancel four days or within a day or two of departure. we then have to run flights that will have, i don't know, maybe five or 10% of the seats sold. we lose so much money. it makes it, the only way

we can survive this is to not operate the flights at all. the government has said that policies like travel corridors, quarantining and the test to release programme have helped manage important infections before, but with new variants of the virus, infections before, but with new variants of the virus, it's clear the government want to go further. caroline davies, bbc news. this week, we are tearing into 2021 at full pelt, but what technology wonders may it hold? we will ask the experts. and no, you are not having a bad dream, butan no, you are not having a bad dream, but an artificial intelligence is. hey, welcome

to click. happy new year? i hope you got some respite and a bit of a break recently. lara lewington, how are you? i am good, all things considered. resolutions? i don't do resolutions, that means i can't break. i decided to stay home and watch more tv. your plans for the next few weeks?” and watch more tv. your plans for the next few weeks? i think i will have a quiet start to the year and then, i guess we can only hope but in the meantime, if you are having that january wanting to get fit feeling, it is going to be a bit harder than usual this year but you could take advantage of some of the tech forms that did really well last year. they certainly benefited from the at home exercise boom. one of those companies is zwift, a virtual cycling club form who subscribers are in the millions. the competition has been taken to extreme levels and jonathan coates threw

himself into this to find out more. for many, cycling during lockdown offers escapism and more people than ever are hitting the roads. but for a growing number, the roads they ride on aunt with tarmac. cycling is a sport that has a lwa ys cycling is a sport that has always embraced technology and 110w always embraced technology and now it has taken a leap into the virtual world. zwift is an on line platform that allows professional and amateur cyclists to compete against each other. its popularity soared during the pandemic and it now has more than 3 million subscribers. by putting a normal everyday bike on a smart trainer, basically a treadmill for a bike with a bluetooth connection, a rider's output is converted into a moving avatar. —— avatar. in zwift, the resista nce —— avatar. in zwift, the resistance levels change depending on gradient and conditions and there is a whole host of other tech that can add

to the realism. more advanced trainers simulate going over cobbles and dirt tracks and there are even firms that can match the wind speed to how fast you are sparkling. —— ferns. but once you are plugged m, ferns. but once you are plugged in, you just need to start pedalling. a group ride, a workout or cruise around some of the best routes in the world with maps, stats and data. sue to see what all the fuss was about, i thought i'd get stuck in. ——so. the aim, infive weeks, to take part in a race on zwift and in order to do that, i recruited matt rowe, professional cycling coach who trains people through zwift. professional cycling coach who trains people through zwiftm is great, for those who have four or five hours a week, right through to professionals. indoor training, the benefits it brings to performance gains speaks volumes. there is one key metric which seems to be the lifeblood of zwift and that

is watts. to put it this way, your tv needs about 250 watts to work and olympic gold—medallist radley wiggins broke the hour record by generating an hour average of 440 watts just with his legs. thanks bradley. zwift claims to bea training thanks bradley. zwift claims to be a training plat form and this can replicate many training conditions with genuine road speeding conditions meaning the data you gather is comparable to real life. matt has sent me a test tonight to see how fit i am. basically, it's to see how hard i can push myself and how many ican i can push myself and how many i can generate. i've got my screen down here where i can see the training plan. i've got to do what he's put me on. it's 45 minutes and it looks pretty brutal. at the moment, i'm doing 167 watts, or

thereabouts. my legs are really, really starting to hurt 110w. really, really starting to hurt now. that was one of the ha rd est now. that was one of the hardest things i have done for a long time. i mean, look at me. it'sjust horrendous. certainly i had some work to do and the training carried on five days a week for five weeks. but while you can train ha rd weeks. but while you can train hard and make real gains, it feels like competition is the pinnacle of zwifting. it is where zwift goes for the company and uses itself, going from training folks to something more akin to an e sports but form. you can select to race, turn up at the right time and you are suddenly on the starting line with a huge group of other riders and if you are good, there is serious money to be made from winning. i've heard from several zwifters who said i made more money on this zwift race than

any actual race. there have been some big competitions. at a recent championships, the prize money was $10,000 for the winners. incredibly, female cyclist ca n winners. incredibly, female cyclist can make more money racing from zwift than in real life. so after five weeks of training, five days a week, the time had come. it was race day. at 12:30pm on tuesday the race began. i had match there on zoom to coach me through. —— i had matt. that's the most painful thing i have ever done. it was genuinely really fun. there is a real kind of thrill bracing. it must be unique to zwift. if pa rents bracing. it must be unique to zwift. if parents are worried about kids doing too much gaming at home, do this, they will get fit, and you can't do it on more than 45 minutes or you will fall hour. time for

the results. five weeks ago i had a functional threshold power of 230 watts. so how did it work? 38 minutes, you went 288 watts. an extra 30 odd watts , 288 watts. an extra 30 odd watts, 34 watts, nearly twice and that climb. gosh. it's a huge strike. that's a massive increase, isn't it? it's massive. out of 32 riders, you came 14th. good result, you've got to be happy with that. what we call sandbag is in the group. there were two riders who were minutes ahead of third—place and the cs. who were minutes ahead of third-place and the cs. there we re third-place and the cs. there were two guys in the race in my category, category c, who were considerably faster than eve ryo ne considerably faster than everyone else, in fact, they came first and second with a minute between third—place and these guys who essentially are category a riders, they are

really fast, really large, really fast, really large, really powerful, competing in lower categories. you know, i came 14th that it sounds like a good have come 12th. and ifeel a little bit like, ifeel a little bit cheated. perhaps where there is competition, a lwa ys where there is competition, always going to be cheating and professional cycling has had its fair share of scandals and 110w its fair share of scandals and now zwift is going to deal with digital performance enhancement and other methods of —— manipulation but as i found out more about cheating on zwift, one name kept coming up.|j more about cheating on zwift, one name kept coming up. i can say the skies name, cam jeffers, because it was always on the news. i don't like to be compared to lance armstrong and i think it's unfair to be compared to lance armstrong. i think it's unfair to be compared to lance armstrongm 2019 cyclist on youtube cam jeffers took part in and won the inaugural eu racing championships on zwift but shortly after the race he was

given a six—month suspension from all racing after british cycling ruled it had breached their disciplinary code during their disciplinary code during the championships.” their disciplinary code during the championships. i got a call one day from british cycling saying they had an anonymous complaint that my bike wasn't legit and you know what? come and check the bike if you want. zwift the charge related to zwift the charge related to zwift using a bot to write to him to unlock a special biking game, thus giving him an unfair advantage over his competitors. he claims the obtained the bike for a series of youtube videos he was doing earlier in the year rather than the race. qualifies, i remember saying to a couple of people, should i not be using a bike that i've legitimately had and they said, there is no rulebook, there are no rules written for this event, so there is no way you

can geta event, so there is no way you can get a ruling you haven't legitimately obtained. just like in any sport, there is a battle between regulating and those trying to gain an advantage. cheers. it was good they took it away from him but i think he could have one without the tron bike, so that is the sad thing. zwift are cracking down on any attempts to cheat on their races with the help of global cycling bodies. if it wants to be taken seriously, it has to maintain its sporting integrity. seriously, it has to maintain its sporting integritylj seriously, it has to maintain its sporting integrity. i think cheating is probably something we will have to combat. it will never go away. someone will figure out how to game the system and having said that there are things we know we can do including hardware, so for example, the world championships this year, eve ryo ne championships this year, everyone will be on the same bit of equipment. in addition to real world anti—doping controls the father use performance—enhancing drugs, there will also be a group of a nalysts there will also be a group of analysts monitoring rider race data or red flags compared to previous performance stats.

other just five weeks previous performance stats. otherjust five weeks of using the platform, i got so much better but really i was hooked, it was the social element though and a gasification that can be coming back. people were showing up not for training but because they crave that social connection. if i think about what credit you could be, it is certainly much larger than bike racing. as a community. if it isa gaming racing. as a community. if it is a gaming training tool or any sports training platform, zwift is set on something that has resonated with cyclists. and the key to this is the community that is building a few tubers, live streamers and online trainers, and social groups. hello and welcome to the week in attack. it was the week that a request to extradite wikileaks a request to extradite wikilea ks founder a request to extradite wikileaks founderjulian assigned to the uk to face espionage charges in the uk was denied by a court in london. employees from google and its pa rent employees from google and its parent company alphabet started a new labour union called the

alphabet workers union. and volkswagen showed off its prototype fully autonomous electric car charging robot which it says will work in places like underground car parks. there were also reports this week that billionaire founder of chinese tech giants alibaba jack ma had gone missing after he hasn't been seen missing after he hasn't been seenin missing after he hasn't been seen in public since october. mrma had seen in public since october. mr ma had been critical of chinese financial regulars is not being innovative enough for technology development. mr ma had been preparing to list his group in what would be the largest initial public offering, but regulators shelved the listing after his criticism. data from singapore's cove two contact tracing up coming up trace together can be accessed by police despite previous reassu ra nces of police despite previous reassurances of privacy. it initially, they said data collected in the app would only be used for virus tracking. researchers at 11 in the have showed a robot with their body made from ice. the concept, eyespot, could be used in

remote locations like antarctica and even mars. the robot was able to claim icy inclines of 2.5 degrees and clear by obstacles from its path during testing. 2021, what on earth does it have in store for us? hopefully some better things than 2020. we have asked some leading tech experts to give us their predictions of things that might be just around the corner. boston dynamics kicked off 2021 in style with a robot routine fit for dirty dancing. the twisting isn't all droids are getting up to this year. i think we're going to see in 2021 is the increased prevalence of robots coexisting in spaces with people. most robot helpers working today sip around controlled areas in factories or warehouses where bystanders can't get in their way. but

many robots are coming to public spaces like shops and hospitals. you may have people who are completely unaware that there might be a robot driving down a corridor. firms like starship technologies have even run on street pilots before but 2021 rings unprecedented momentum. the market wasn't necessarily crying for more kinds of delivery but is now because of covid ands in agriculture because of brexit, we are seeing the market looking for solutions. but, very picking prototypes like this won't be the first to scale. running from the field to the pack house and back and collecting new trays, loading punnets onto trays, kind of tasks where you could have a robot doing that. so what needs to happen first? you have very large test groups and you build up large test groups and you build up an large test groups and you build up an assurance large test groups and you build up an assurance that the likelihood of something going

wrong is minuscule. an area with other growing risks is cyber security. on your smartphone, app developers can build in tools taking advantage of the devices operating system to make the app safer. but that is not the case across the board. there are other systems that we rely on, whether that is automotive or medical or your smart city functions, but end up building every component themselves. we all can't be expert that everything so this is the year that they recognise that it is the year that they recognise thatitis is the year that they recognise that it is hard to do everything yourself. a shift is needed but to what? well, it makes more sense to leverage security functionality from platform so we are not always reinventing the wheel with every different development team. there should be some places where it's appropriate to find, like libraries, find support from the framework on the platform. if you're wondering what's the worst that

can happen if somebody acts your smart speaker? well, it's not just about turning the volume up. even if those devices are not managing anything sensitive, right, or you may not consider sensitive, they are still a launching point to attack your laptop or your ipad. but although some data is best kept private, in some cases, it is better shared. even all around the world. 2021 will be the year when for the first time, truly global collaborative artificial intelligence community will start working together. some global data initiatives do exist but are generally limited to specialisms like cancer research in health orfraud analysis in finance. what is actually to combine all of this data to gather into a single purpose of information. it is a

technical feat, purpose of information. it is a technicalfeat, sure, but there isa technicalfeat, sure, but there is a bigger impact year. if you wa nt to is a bigger impact year. if you want to know how to improve the healthcare systems, where do you start investing? and this investment will improve healthcare, what about schools, what about traffic, housing? all of these items are correlated and artificial intelligence will help us understand that ecosystem as a whole much better. fascinating. let's see what comes to pass, shall we? 0k, let's see what comes to pass, shall we? ok, let's talk about something completely different now. lara, you know when you look at the clouds, sometimes you can see things in them, yes? oh yes! won the best photo, i took this over christmas. it looks like two angels having a chat. i'm a lwa ys angels having a chat. i'm always seeing things that there, a bit like you're in a dark room and as a shadow and you convince yourself it is a person completely terrify yourself. row, ok, exactly. but if your brain making connections in your mind spotting patterns that aren't really there. it turns out that

artificial intelligence can also have an overactive imagination. so, you know how image recognition software works, yeah? yes, you feed it isa works, yeah? yes, you feed it is a pictures of dogs so it can identify dogs for itself and thenit identify dogs for itself and then it will see dogs in pictures. right. but if you ask it to look too hard, it will start seeing dogs everywhere. now, there is this google researcher who is name is alex and he decided to turn this concept into art. he is the man who created google deep dream. it happened in the middle of the night and i woke up with some weird dream of somebody entering the apartment and i woke up and it was 2am and i had this idea that i wanted to try and i was like, what and i spent half—an—hour coding. and

there was this cat and dog picture i was using as a starting point for that. images i got were so surprising to me that i shared them in internal message boards. i think the exact text was something like, 0k it is 2am but how can i sleep now after seeing this. the sun never sets on the google empire. and while alex was sleeping, it was afternoon in mountain view california and the image was going viral at the image was going viral at the headquarters. the unknown engineer from the headquarters. the unknown engineerfrom the zurich the headquarters. the unknown engineer from the zurich lab was famous. i posted the actual code into our internal depository in the next week there were hundreds of people playing with this and some images started leaking externally and i have seen the reaction of people outside. what the hell is going on, what is this? a lot of people were saying that this is similar to

like a hallucinogenic experience. we do see weird things, we do see weird things on alastair. some of the images from deepdream seem like hallucinogenic images and that could point to a connection between machine vision and the visual cortex. right now, machines are quite primitive, quite narrow. they can run deepdream and that is all. but we are running lots of different algorithms. we are machines, we are running algorithms all the time. and out algorithms all the time. and our algorithm can run awry. we can see things that aren't there, like a face on the moon for example. look at a cloud formation and you can see things in it. there are no birds in those clouds. then, my

wife came along and said let's print some of the things you did, like these prints here, and also there were a couple of people who were really wanting to buy prince from me. so from that point on, i decided, 0k, to buy prince from me. so from that point on, i decided, ok, i can probably call myself an artist as well — no prints. artist as well - no prints. we know that artificial neural networks work but were not sure how they work and it is a central problem in al because after all, artificial neural networks power driverless cars, as well as payroll and the internet of things. and if artificial intelligence takes charge of critical systems and then goes wrong, it will be crucial for us to understand what is going on in the layers of its brain between the inputs and the outputs, between the stimulus and the corresponding actions. we hope that this work

can shed some light on internal duration of the neural networks. it is probably when we design control systems that we design control systems that we should make sure that they function in the situation where even inputs can't be trusted and outputs malfunction. i don't think that we are at this stage of full understanding stop maybe there will be at this idea of computer psychiatry. well i this idea of computer psychiatry. well! guess this idea of computer psychiatry. well i guess we could do with a bit of dreaming right now but that isn't what i had in mind. yes, that is way too much isn't it? anyway, that is it from us for this week. as ever, you can keep up with the theme of social media. find us on youtube, instagram, facebook and twitter at a cyclic. thanks for watching, don't have nightmares and we will see you soon. nightmares and we will see you soon. goodbye.

hello. there are some hints that the weather will be turning less cold as we had for the course of next week's but certainly to start of the weekend, bitterly cold out there. minus double digits for some areas, could be as low as -15 some areas, could be as low as —15 celsius across the shelter glens of scotland. some freezing fog lingering across parts of england and wales legal part of the day. many passes dry for a saturday and some sunshine for part of northern england, north wales and eastern scotland as well. we have got a front moving on from the north—west bring a marina mountains know to be north—west of scotland. out of that, temperatures typically three — five degrees, not quite as cold as recent days.

overnight, saturday night into sunday, more cloud filters out into the country but south wales in southern england still clear and very cold once again. so some ice and frost to start off sunday morning. sunday will be cloudier in the north and the west with some patchy rain, mountain snow. drier and brighter towards the south and the east as well and temperatures typically around four — seven degrees. goodbye.
