hello, this is bbc news. the headlines... national and family triumph forjapan injudo, as a brother and sister both win gold. austria's anna kiesenhofer causes one of the biggest shocks in olympic road racing history with an audacious victory in the women's cycling race. and africa wins its first gold medal, as a tunisian teenager stuns the field to win the men's 400 metre freestyle. thousands of people in the western united states, are spending the weekend in evacuation centers, as wildfires continue to burn across the region. more than 80 large fires in 13 us states have burnt around 1.3 million acres in recent weeks. british mps have warned that taxpayers will bear the cost of the government's coronavirus spending for decades.

sport, and for a full round up, from the bbc sport centre, here's austin. good afternoon. well, team gb are on the board. they have their first medal of the tokyo games and it came in thejudo — 24—year—old chelsie giles winning a bronze in the women's under—52kg event. she beat switzerland's fabienne kocher in the bronze medal final. she scored an early waza—ari to take the lead and then won the bout with this ippon to make her team gb�*s first medallist in tokyo. but the brits are guaranteed another medal within the hour because bradly sinden is into the men's under—68kg final in taekwondo. so that means he's guaranteed at least a silver. but if he wins, he'd be

the first british man to win a taekwondo title at the games. and sinden got there after a dramatic semifinal win over china's zhao shuai. sinden was well behind going into the last minute of the third and final round, but a brilliant late onslaught from the brit sent him into the final. that gets underway shortly at around 1:45pm. but there was heartbreak for two—time gold medallist jade jones. she took the gold in london and in rio but was beaten in the first round of the women's under—57kg category. she was beaten by kimia alizadeh of the refugee olympic team and jones said the lack of fans had a big impact on her. ijust think i put too much pressure on myself — ijust think i put too much pressure on myself. coming out was hard, i felt scared, — on myself. coming out was hard, i felt scared, i— on myself. coming out was hard, i felt scared, i felt too much pressure _ felt scared, i felt too much pressure. and then the whole tournament hasjust been different tournament hasjust been different to what_ tournament hasjust been different to what i'm used to. i'm used to having _ to what i'm used to. i'm used to having my— to what i'm used to. i'm used to having my family there. then cheering _ having my family there. then cheering for me gives me the extra

push _ cheering for me gives me the extra push to— cheering for me gives me the extra push to go— cheering for me gives me the extra push to go for it. like i said, i just— push to go for it. like i said, i just kind _ push to go for it. like i said, i just kind of— push to go for it. like i said, i just kind of got trapped in that fear motor today. just obviously devastated. i think i could have done _ devastated. i think i could have done more, but i give it my best under— done more, but i give it my best under them _ done more, but i give it my best under them circumstances, and just obviously— under them circumstances, and just obviously gutted and wish i could have brought back the gold for everyone — have brought back the gold for everyone at home. disappointment for andy murray, too. like jadejones, he won gold in 2012 and 2016, but this morning he pulled out of the men's singles with a minor thigh strain. murray, who won the first round of the men's doubles with joe salisbury yesterday, was due to face canada's felix auger—aliassime today. he will continue in the doubles, but in a statement he said he'd been advised not to do both events. the big upset on court, though, came in the women's singles. the world number one ashleigh barty,

who early this month won the wimbledon title of course, was knocked out in the first round. she was well beaten by sara sorribes tormo of spain in straight sets. japan's second seed, naomi 0saka, cruised into the next round. the world number one is out of the men's golf tournament, too — but that's before a ball has even been hit. spain'sjohn rahm and the american bryson dechambeu have both tested positive for covid—i9 and have been forced to withdraw. rahm tested positive less than two months ago, too. when he had a six—shot lead after the third round of the memorial tournament in ohio. they both returned positive pcr tests from the open at royal st george's last week. neither had yet travelled to tokyo.

adam peaty is safely through to the final of the men's 100 meter breastroke. he topped the time sheets to remain on course to become the first british swimmer to retain an olympic title. but the headlines on day two in the pool were saved for 18—year—old ahmed hafnaoui. the tunisian was the slowest qualifier for the men's 400 meter freestyle final, so that meant he was in the outside lane. but a brilliant swim saw him take a shock gold — tunisia's fifth ever gold at the games. and there was a shock winner in the women's road race, too. austria's anna kiesenhofer taken the gold after breaking away from the pack within the first kilometer of the race. she lead for almost every meter of the 137k — she was so far in front of the rest of the pack, that second—placed annemiek van vleute thought she had won the gold, only to be told on the line. but it was kiesenhofer who won austria's first cycling medalfor 125 years. that's all the sport for now. you can find more on all those stories on the bbc sport website.

that's bbc.co.uk/sport. great, austen, wonderful to see the reaction. now on bbc news the travel show�*s in tokyo, host city of the olympic and paralympic games — to find out how its hotels are dealing with the influx of athletes and trainers from all over the world. if not tourists. this week on the travel show... 0utrunning covid at the olympic games. the big names rocking central park this summer. siberia's mystery blast craters. to have an exploding crater on land is not something i imagined. and the fears for the future of flamenco.

hello, and welcome to tokyo. the host city to this summer's olympic and paralympic games and thronging with tourists and sport fans from all over the world. ok, maybe not. the state of emergency declared earlier this month following a new wave of covid cases means that international and now local spectators are not allowed in to any event in and around tokyo. nonetheless, athletes, trainers and medical staff have headed here from all around the world for a more subdued games.

there were plenty of people here in tokyo who were delighted to see the olympic opening ceremony on friday. even if they had to resign themselves to only being able to watch it live on tv rather than in person at this vast stadium. however, they could be a minority as recent surveys showed thatjust over 50% of people here did not want to see the games go ahead. japan has declared a state of emergency for tokyo that will run throughout its hosting of the games. and public concern has grown over what impact the influx of thousands of athletes, support staff, officials and press from overseas could have on infection rates. for me, like many people here in tokyo, the olympics has been a roller—coaster. in 2019, i got tickets for athletics and diving events

in the first round of the lottery. and then last year they were not even sure if the olympics would go ahead and then we were told this year that our tickets would have to go back into another lottery because of limited capacity of the stadiums and then finally, two weeks ago we were told that there would be no spectators at all in any tokyo events. and here, there was meant to be a fans zone with a big screen tv but that idea was quickly quashed. pre—covid, japan was originally expecting around 35 million visitors in 2020. but now only vaccinated athletes and officials can attend the tokyo games this year. that number has been massively reduced. and with the capacity of the olympic village limited, many of tokyo's hotels are playing host to athletes and sports support staff from all over the world, with strict sanitising protocols, regular testing and in some cases curfews and other restrictions now in place. this hotel was not allowed to tell me which teams would be staying here but they were willing

to show me some of the adjustments they had made to ensure that their sporting guests have a happy and healthy stay. in addition to ensuring the hotel is covid secure, the carpenters here have also been busy at work in readiness for some extra tall special guests. we had some requests for larger beds so these are wooden bases for the extension, and we will have 12 of them. so i can assume you will have some very tall athletes staying? you are correct. the normal size bed is two metres so we're extending it by 30 centimetres. here we are. this is the room where we have put a larger bed for our guests. wow. this is a big bed. good, hey? and you cannot notice where our carpenters have made the extension. very neat.

and it's notjust a good night sleep that the olympic competitors need. nutrition plays a vital role in their performance so the kitchens here have had to adjust their menus accordingly. they want at least eight different salad bars, so it can be from carrot, cucumber, celery, broccoli, cauliflower, you know? they prefer to have it rather than cooked. i have designed a menu, here i have added three carbs, i have three protein and i have five different vegetable. the nutritionist and the chef look at it and they come back to us and see if it is ok or not. so it all has to go back to their nutritionist? yes. so i see we have salad, grains, is there a dessert? a little dessert. they cannot have too much sugar because when you add sugar... the dessert is more like a bite.

they call it energy balls. so what are we making today? apricot cashew bites. this is what olympic athletes will be eating. quite good. and very healthy. super healthy. not quite the dessert i was expecting. i think everybody's getting used to the new normal, getting used to the fact that these olympics are now without spectators so there is a drop in demand. however, everybody is still preparing for the groups that are coming, the people they have to look after and making sure the event is well executed. traditionally, every olympic games always now has a small army of local volunteers who sign up to help ensure that visitors have the best experience possible. but with the ban on spectators and overseas tourists, many of the volunteers have either been stood down or seen their duties changed.

where do we get the bus from? you are here now. mak san was looking forward to meeting travellers from all over the world, but now he is using his english to help out at the press centre instead. i wish the olympics would succeed without any problems. are you looking forward to seeing some athletes and some olympic events? yes. i love sports. i was a pe teacher. 0h, oh, great. so this is your dream job? yes. my dream job. of course, a modern olympic games is not just about sport. there's usually a whole host of marketing opportunities, corporate events and collectables associated with each games. daniel, tell me about these pins. every national olympic committee

likes to have their own pin and athletes, it gives them an opportunity to give a gift from their country to somebody from another country that they may not necessarily interact with. this rwanda versus godzilla... yeah, we've got amahoro, the rwanda team mascot, against godzilla. it's a pretty epic pin. this is a mega mecha. a moving parts pin. that's great. there is an entire network of collectors from all over the world. it is known as the unofficial olympic sport, collecting pins and trading pins. so, unfortunately, there are many collectors who would normally come to the games just to go pin trading and just to collect. it will be a little more difficult this time around to get their hands on some of these prized possessions. it's estimated that back in 2019,

over a quarter of a million fans from overseas travelled to japan to see the rugby world cup championship. staying, on average, for 16 nights and each spending around £11000, or 5500 us dollars on their trip. so hopes were high that the postponed olympics would bring in even bigger numbers, more revenue and greater positive publicity for the country. i don't think there has ever been any event that had the demand that the tokyo 2020 had. they really wanted to come and experience japan. the japanese hospitality, the food, the culture. it's only the fourth time in history that there has been a summer games held in asia so i think itjust provided a unique catalyst for the entire world to go, "i want to be there." and, i guess, that is what makes it incredibly disappointing.

so, no matter how you feel about the games, tokyo 2020 is happening at a unique and historic moment in time. and many people will want to capture that and reflect on it. the shops here are still full of memorabilia and souvenirs. how much will be sold, though, is unclear given the lack of overseas tourists. one thing is clear, however. you can expect souvenirs to maybe become items in their own right. because they certainly represent a very different olympic games. the edinburgh festival looks a bit

different this year. but they are going ahead. the international festival has moved many of its performances outside and kicks off with a three day event in the royal botanic gardens. the fringe, meanwhile, mixes its socially distanced live in person shows with a live online offering that starts on august 6th. new york is planning what some people are calling a mega—concert on the great lawn of central park. bruce springsteen, paul simon and jennifer hudson will headline the event, which is part of week—long celebrations of the city's reopening. 60,000 people are expected to go, with different sections allocated to vaccinated and unvaccinated spectators. berlin's museum island has a new landmark, the humboldt forum. this vast building brings together the ethnological museum and the museum of asian art in one enormous reconstructed baroque palace. its remit is to be a symbol of tolerance and diversity,

but there has been controversy over its decision to house artefacts looted from parts of the world once colonised by europe. and barely a year goes by without dubai opening something enormous. this time it's the world's deepest pool. deep dive dubai goes downjust over 60 metres and holds enough water to fill six olympic—sized swimming pools. they've built an abandoned city at the bottom to explore, along with a library and an arcade. still to come on this week's travel show... the blast craters causing confusion in siberia. and with one final click of the castanets, a flamenco venues saying goodbye for the last time. so don't go away.

next this week, we are in russia on the remote siberian peninsula of yamal. scientists they have noticed enormous blast holes appearing in a landscape and it has had them scratching their heads. so we thought we would catch up with them to find out more. i first heard about these craters when i was contacted by a reporter in 2014, i came back to my e—mail and thought this is a crazy e—mail i got, this person is talking about these craters and i didn't have accessibility to the news, ijust didn't believe it. i got back to the states and i read a little more and wow, this is a thing that happened.

the fact that there could be a new geochemical process that we never imagined would happen, have an exploding crater on land is just not something that when i think about the processes that can happen on the earth, is not something that i imagined. how important are these? so this idea that what is the cause of these, is this something that is new that is happening, is this related to climate,

is this something that is a risk to people who are in the arctic, to the gas and oil infrastructure, which is quite close to the area where these craters have been occurring? and then is there some long—term impact on global climate, because there is methane that is coming out of these craters? it's an area where there is very thick layer of ice called tabular ice, and there is also an area where there is a lot of cryo—pegs, which is an area of ground that is within the frozen permafrost, so it is an unfrozen sandwich, it is surrounded by permafrost, it is unfrozen ground, and the idea of how these forms is that these very deep deposits of gas are sort of finding their way to this unfrozen pocket, this cryo—peg or a talik, and then as pressure builds up

it raises the ground up, and it explodes. how many more of them are out there? what we're trying to do is use satellite data to view these craters — what we have first done is create a change detection map which is an automated method of picking up pixels on the peninsula that have changed in some way. that algorithm was built based on sort of what we know about the craters. so once we have this change of texture map, we have a team who are using high—resolution imagery to look through each one of these pixels and say, does this look like a crater, does this look like something else, and from there once we have something that we think looks like a crater or could have been a crater, we are getting a series of very high—resolution imagery to try and figure out where these forms.

why are they happening now? it is really tricky to identify. i would not be surprised and i do think it is likely that warming temperatures are at least in part contributing to making the ground unstable, allowing these explosions to happen. to me, they're more an indicator of what's happening, and a very shocking indicator of what's happening in the arctic. and there's nowhere else on the planet that i know of where climate change is causing the physical structure of the ground to change. it's quite startling.

the unfolding mystery of siberia's enormous blast craters. right, to spain next, and an art form that so many of us see on our holidays. flamenco happens in venues called tablaos, which like so many venues have had to close — sometimes for good. we have met some dancers in madrid who are now facing an uncertain future.

that's it for this week. coming up next time... christa's here with some of our favourite memories of new york city. from historical landmarks to hidden treasures. and the time she was made to face her public speaking demons once and for all. and i was like, "oh!" don't forget you can catch up with our more recent

adventures on the bbc iplayer and we are on social media two. just search bbc travel and you won't be far off. but until next time, keep planning, stay safe and we will see you very soon. goodbye.
