reported to the world health organization by south africa. over a dozen countries and territories have detected cases, giving a clearer picture of how long the variant has been circulating. mark meadows, donald trump's former chief of staff, has agreed to make a deposition before the congressional investigation into the assault on the capitol. the committee says mr meadows has already provided records on the incident. former president trump has urged his associates to ignore the probe. entertainerjosephine baker has been honoured with a place in the pantheon in paris. she's the first black woman to be inducted, and is recognised for her contribution to the performing arts, civil rights activism, and her work as a french resistance agent during the second world war. borisjohnson was challenged

repeatedly at his downing street news conference yesterday about guidance on socialising in the run—up to christmas. he urged people not to cancel parties or school nativity plays — despite the advice from a senior health official to limit social contact. but the hospitality sector is worried about the potential impact over the next few weeks, as our business correspondent emma simpson has been finding out. they're all ready for the christmas season at this small wine bar and restaurant, but on monday, the phones started ringing. we've lost, in the last 2a hours, about £8,500 worth of business. we've had a group booking for today cancelled, a group booking for an event out of house at their offices cancelled tonight, and a further three groups later in the week. on paper, nothing's changed for hospitality today. it should be business as usual. but there's a bit of a chill wind starting to blow through this sector, with some customers getting cold feet.

but there are also plenty who have no intention of cancelling any big christmas nights out. we are going to one a week on saturday, and we're not pulling out. absolutely not. you need to do it sensibly, but as long as you do it sensibly, it's nice to have fun again. paul runs three pubs in yorkshire and is worried. he has had lots of cancellations too at what should be the busiest time of year. so important to have christmas to boost them coffers and get you through march. without that, we really are looking... is not looking good.

there's— looking... is not looking good. there's a — looking... is not looking good. there's a lot of uncertainty about the new variant but that's the last thing this sector needs as it tries to get back on its feet. emma simpson, bbc news. now on bbc news, it's the travel show — with lucy hedges. this week on the travel show: iam in dubai, with visions of the future at the delayed expo 2020. if i scan this image here, i get augmented reality view of what south korea deems to be the future of mobility. and that includes flying cars. woo! i take a dip and tumble... laughs and i discover an artificial rainforest in what was once a desert. oh, hello! oh, here we go!

but first, in a difficult couple of years in the global travel calendar, there has been one giant mega event looming. and of course, fitting for a giant mega event, that was to happen in this city of superlatives, dubai. nobody knew for sure it would happen, but here it is. hello, expo 2020, orshould that be expo 2021. it was delayed by a year, and for a place that relies so heavily on tourism, dubai needed this to happen. in fact, it is probably not too much of a stretch to say the entire international tourism industry needed this to happen. well, i'm armed with my expo passport — let's do this.

it has taking place over six months, and had nearly 2.5 million visits in the first month alone. 192 countries have created pavilions showcasing innovations for the future. here in a site twice the size of monaco, you have a world in miniature. looking around this place, one thing to remember is that pavilions are like shop windows for countries. you know, in amongst all the tech and innovation, it's a real chance for them to show the rest of the world their big ideas, and the idealised vision of their culture and values. but for some seasoned travellers, their experiences of these countries might be a little bit different. the first expo, then called the world's fair, started back in 1851, when it was opened by the uk's queen victoria in london. back then, when only a fraction of people ever went abroad, and information about the world was harder to come by, the multicultural innovations

on show, fuelled by the new industrial revolution, would have seemed extraordinary. but now, it is a technological revolution at expo's heart. as you can probably tell, still a work in progress... last year i came to see it in the making, so now i have come back to see how it has all come together. now, the last time i was here, this place did not look like this, it was basically one big construction site. and i can see they have completely transformed it. the uk's contribution presents a huge wall of poetry, which doesn't always make total sense. it's generated by artificial intelligence using words donated by the public, and was inspired by professor stephen hawking's theories about how the world might come together to communicate a message in the event of meeting intelligent life from another planet. so i will type my word in here,

i am going for "beautiful". and now i believe it is going to appear on the big screen. so talk me through the arrangement of the words. because looking at right now, it doesn't look like it makes a lot of sense. so how do we make a story out of this? it is really simple. poetry is very personal. every word is given a single couplet, those couplets will speak to the individual who donated the word, but what is really exciting about this is the algorithm has been trained over many, many months. it has digested 15,000 poems, including shakespeare, including blake and so on and so forth. the poetry societies across the uk have fed the algorithm words and poems, so that it can learn how to create poetry. and the more words we give it, the better the sense of the poetry becomes. and right now it has been up for a few weeks,

and you can see sentences, you can see sense within this building. what we're trying to do with this building is show that we are innovators as a nation. the pavilions each sit in one of the expo's three main themes — mobility, opportunity and sustainability. and each theme has its own building. the sustainability pavilion is net zero energy and net zero water, diverting people's waste water through a natural outdoor filtration system of reedbeds and then reused on the site's vegetation. so all around us you will find buildings that are net zero energy, you will find buildings that have employed sustainable wood technologies and methodologies — shading, outdoor passive cooling areas. and it is actually a real honour to stand alongside all of these country pavilions from all around the world that have chosen to highlight solutions that are applicable to those regions. and trialling them out to see what works here.

and walking around, one of the sustainability pavilions stand out among the others. so there is around 80,000 different kind of plans the tropical garden, and over 190 different species. and it really is so peaceful and tranquil, just wandering through here. and i also think it's kind of crazy that i am in a giant garden that is slap bang in the middle of a desert. in singapore we have more than 250 hectares of vertical green. so what we do here is reflected in what we do in singapore, in a much, much bigger way. five decades ago, singapore is known as the garden city. and until recently, the last decade, we have evolved into a city in a garden. now we are aspiring to be a city in nature. and will be rewilding all our gardens, we will bring

nature closer to the people. once you bring this down to the city, we are bringing the biodiversity closer to them. i think that is what we want to see. and what better proof of that than with their first visitor, a bird that has nested in the pavilion. but for dubai, while all this might seem like a huge boon for the time being, what happens when all the visitors go home and the pavilions pack up and shut their doors? how sustainable is this expo site then? dubai has expanded at an extraordinary pace in recent years, but still, plans are in place to repurpose expo to create a new living and working environment to support nearly 150,000 people as part of a vision for a human—centric future city. this site is huge.

twice the size of monaco, i believe. it is. for the built environment, it is twice the size of monaco. it is massive, so how will you make use of the space, how will you utilise it? 80% of everything we have built gets repurposed. and it is taking this space, this incredible environment that you see from on top of here, and repurposing it into this innovation hub. and it is a blank canvas, really, for us, for architects, for smart infrastructure solutions, for start—ups that want to come into this vibrant environment. dubai is moving towards becoming a very smart city, we are taking the lead in that. it is about creating this industry that is another focal point for dubai. and finally, it's night time when this place transforms into something else altogether.

like at south korea's pavilion, bursting with lights and technology. so if i scan this image here... i get an augmented reality view of what south korea deems to be the future of mobility. and that includes flying cars. but there is one last emerging global superpower i wanted to see. so this is the china pavilion, and one of the biggest pavilions here, you might have guessed it might be — they definitely don't do things by halves, which explains why every night they do a drones and lights performance outside. here it goes! a brilliantly synchronised, stunning display. i expected nothing less.

stay with us, because still to come on the show: i take on one of the world's biggest floating inflatable assault courses... boo! ..and find out how the residents of a very special home here in dubai coped during lockdown last year. the speed with which those things devoured that chicken was unbelievable. the beaches here are one of the many reasons to visit dubai, and as you can see, it is a glorious day, people are enjoying the sun. and i have been told there is a really fun way to cool off here. i'm about to give it a try.

this is dubai aqua fun, the brainchild of a young emirati entrepreneur called ahmed ben chaibah. he claims it is the biggest inflatable water park in the world. against the backdrop of hotels and skyscrapers, and a short 25 metre swim from the beach, you will find a course made up of over 70 floating blow—up slippery slides, swings and other obstacles, all designed to test your stamina, balance and bravery. and after a bit of undignified clamber on board, i am ready to accept the challenge. it is a lot slipperier than you think!

come on, lucy! almost! i think i've — oh! i was just about to say, i think i've been in the water enough. went five seconds and i didn't even touch the obstacle. here we go! boo! laughs. that is what you've got to look out for. you might complete the obstacle but the slipping at the end, every time. every time! something tells me i may have spoken too soon. i challenge anyone to get over this thing and stay dry. i am fit, yeah? i'm trying my hardest! but most importantly, this is so much fun.

three, two, one! all right, here we go! woo! how can you not love the slide? i think i am ready to get off now. well, now that i am thoroughly soaked through, it is time to dry off. but i am not heading back to the beach — instead, perhaps it is time to feel the wind in my very wet hair. how's this for a socially distanced experience? these are the dubai hero boats — your own personal speedboat that lets you cut through the warm waters of the gulf at speeds of up to 50km/h. after a short instructional and safety tutorial, you'll stick to a vast

but designated course, accompanied by a guide who's on hand to ensure that you stick to the rules while getting a high—speed and unique view of the dubai beaches and skyline. as far as rides go, this one is awesome. it's super easy to drive and brandon's nearby for safety, just in case. you know, yeah, you could go pretty slow but the real fun begins when you crank up the engine and, more importantly, you do it with no mask! well, to finish off this week, we're heading to a place here in dubai where, despite the heat outside, it rains as regularly as clockwork inside and it's home to some rather special residents, and i've been to meet some of them. this is green planet dubai —

a purpose—built biodome where, no matter what the temperature is outside, inside, it is a different story and that's because of the thousands of animals, birds, fish and insects that live here. this is just amazing. i mean, you've got a rainforest in the middle of the city. how, how, how? tell me about the building. so the building itself, its temperature and humidity controlled all year long. yeah, yeah. perfect tropical environment right in the middle of downtown dubai. chuckles dubai is not a place that's kind of synonymous with nature. but dubai is known for doing things unique, so the only rainforest in the middle of dubai shouldn't come to a shock as anyone. cackles so this tree here is artificial and then everything growing off of it is natural. i can't get over this soundtrack — it's so beautiful. relaxing, isn't it? it's very tranquil, isn't it? it is, and it's funny when you start really seeing the animals and their personalities, so the toco

toucan over, he is the boss of the birds. yep. he's in charge. so everyone has their kind of place and their homes and their personality and it's just a lot of fun to watch. yeah. and how many different species of animal are in here? there's hundreds of different species, thousands of different animals. you have the bestjob. thank you so much. i know, we're very lucky. we're — every day is a little bit different, though. it's like working with kids — you can't predict what's going to happen by the end of the day. yeah, yeah. every time you think you have them figured out, someone'll surprise you and get themselves in a situation where you go "i did not even know that was possible". yeah, yeah! how did you decide what animals actually go in here, you know, because they all have to play nice together, i presume. it's a very particular process to look before we bring any new animal. educationally, what would they bring to the facility? how they would work together with the other animals. do they have the space and all the requirements that they need? our last new animals where our three ring—tailed lemurs that you'll see

today and the first day that they came, right after lockdown, they were introduced, they kind of came out and i swear to you, there was about 100 birds all around them gathering like... who's the new kid? exactly! so there was a whole introduction process that they have to get used to and pass the test. yeah, yeah! but now, they are settled in like pros. but in the building, we try to be sustainable as possible, whether it has to do with the grey water recycling programme, with eliminating as much as possible single—use plastics. we also have many different critically endangered conservation breeding programmes for animals here in the building for the survival of these species as unfortunately, there's a lot of species becoming extinct in their natural habitat every year. yeah, yeah. we're trying to do all we can to just help them stay alive. yeah. we hope every one of our guests comes, experiences, has a great time, but leaves with a little bit more of a passion to take care of the environment.

come here! oh, they are both back! oh, hello. oh, here we go! i love that there's just no fear. i don't think i have ever seen animals be this brazen before — collectively as well, you know? honestly, that's because it is their home first, right? so these guys are confident, knowing they can be wherever they want to be and guests can come nice and close but won't be touching any of the animals and therefore, they can be wherever they want and explore. oh, hejust did a little twirl for the camera. you just want to have some more nuts? so when guests, when visitors come, they are told no touching the animals, you know — got to be strict about that, obviously. yes. we do have particular programmes where you can, in a small group, get to know the animals more close—up if that is something you would like to do, but in general with our larger quantities of guests coming through, we'll observe them on a little distance so that they can be comfortable coming to see you. and that's why we can have the sloths, the monkeys, the birds, the lizards all kind of doing their own thing.

it's so fascinating just watching the way he eats. in the claw, using the beak to scrape the nut. when the pandemic hit last year, it must�*ve been so tough for you. it's not what you guys can flip the switch off, go home and come back in a few months. no, definitely not. so considering there are thousands of animals and plants around here that are relying on us for their survival no matter what, but we knew that's what needed to happen and so it's what we were happy — more than happy to do, and that is how we got through it. in addition to being able to see wildlife from the aerial walkways, there are also programmes here that give you the chance to get up close to some of the more intimidating residents, like a shoal of deadly flesh—eating hungry piranhas. matt, are you sure this is safe? absolutely, it's safe. i've noticed you've got a cut on your hand. is that cool? yeah, not a problem. it's alright to roll with you?

yep. chicken — just doing their chickens, we're gonna watch from about 1.5m away. yep, yep. it'll be absolutely fine. and how many piranhas are in here? around 500. 500, nice. yeah. 0k. i'll see you on other side. chuckles. sounds good! let's go. thankfully, iam not on the menu today, which is a blessing considering how hungry these fish look. the murder from psycho plays. god, the speed in which those things devoured that chicken — chuckles — was unbelievable. i had to keep telling myself "they're not gonna eat my feet. "they're not gonna eat my feet." but interestingly, it was not the piranhas that was the most terrifying things. the pacu — the size of them! they're like this! some of them at the bottom are even bigger, so i think that was the more disconcerting thing for me but that was brilliant. i learned a lot

about piranhas today. they don't want to eat me, and that's good. towards the end of every day here at green planet, the artificial heavens open and the whole biodome is soaked in a warm tropical downpour as some of the more nocturnal animals wake up and others start thinking about heading for bed — which is exactly what i'm going to do, thanks to an overnight camping programme they also run here. so the last thing i thought i would be doing when i was told i would be coming to dubai would be camping overnight with nothing but lemurs, parrots and a tarantula to keep me company. i have a feeling the morning is going to be very early and very, very loud. the lights go out at midnight. wish me luck. owl hoots.

sleeping in a tent inside a building that's pretending to be outside. only in dubai! well, that's all we've got time for this week but do join us next week, if you can, when... buongiorno! christa is in sardinia, one of only a handful of designated uber—healthy blue zones around the world where your chances of living to 100 and beyond are pretty high. 0h! all this, and you live a long life. it's a pretty good way of life, i think. do catch that if you can and don't forget, you can watch more of our adventures on bbc iplayer. and from me, lucy hedges and the rest of the travel show team here in dubai, it's goodbye.

hello there. after a spell of cold weather, the final day of november brought a return to something milder, something much milder, in fact — westerly winds which fed a lot of cloud across the uk but brought temperatures of 12, 13 or 1a degrees in many places. away from the far north, cold air clung on across shetland and that cold air has been staging a return over recent houi’s. this area of low pressure has worked its way through. and that plunge of cold air will continue to take effect as we head through wednesday, the first day of december, the first day of the meteorological winter. and it will feel like it for many of us. there will be some spells of sunshine, but we'll see showers or longer spells of rain drifting southwards, some wintry weather mixing in over high ground, especially across the northern half of the uk. and if we do see any showers into northern scotland

through the afternoon, they are likely to fall as snow to very low levels indeed. it will remain windy, particularly gusty winds around the coasts, gusts of a0 to 50 miles per hour and temperatures, if anything, coming down as the day goes on. so, afternoon values between two and nine degrees. with that brisk wind, it will feel cold out there. now, through wednesday night, we will see some clear spells, some wintry showers, too. could see some snow to relatively low levels across parts of eastern england. certainly snow to low levels in the northern part of scotland and temperatures, well, they will drop very close to freezing, below freezing in places. a widespread frost and perhaps some icy stretches to contend with on thursday morning. still quite breezy to start thursday. still some wintry showers, particularly in the east. but this area of high pressure is going to be trying to build its way in, so that means we will see more in the way of dry weather. as we go through the day, the showers will become fewer and further between. there will be more dry weather, some spells of sunshine, although our next frontal

system will be introducing cloud and some rain into northern ireland and the far west of scotland. a very chilly feeling day indeed, highs between three and nine degrees. and then another change in the weather as we move out of thursday into friday. this frontal system pushes eastwards. some snow on its leading edge, but this will be introducing milder air once again from the atlantic, so a bit of rain around in places on friday. there will be some good spells of dry weather as well, but it will feel milder to end the week.
