as coronavirus infections begin to rise again there is an increased focus on how to ensure that schools can remain open gci’oss ensure that schools can remain open across the uk. now two big new research projects have received funding to investigate how the virus might be transmitted in schools. 0ur education editor brandon jeffries has more details. at the school front door, the first reminder of coronavirus, the risk their education will be disrupted again. but these pupils in bristol could help change that. taking a saliva test for the virus once a month, so cases without symptoms are spotted. if you do know that you have it, then you can stay at home for, like, two weeks and make sure that you've fully recovered. at such a critical time, learning obviously our gcses, so keeping school open for our year right now is probably the best thing that can happen. the benefits are of testing like, you know you can take precautions, you can quickly isolate, and help others stay safe. for the first time since march, all pupils are back. cases are rising in towns and cities across england. understanding any links is now urgent. we know remarkably little about transmission between children, because there's been so little testing in schools. and without that knowledge, a winter of disruption lies ahead, because so many of them may get the virus and not show any symptoms. this is the scientist hoping to find some answers. her team will test 4,000 pupils and 1,000 staff. here we are with a project that we have co—created with schools. at the moment, schools often don't know who has or has had the virus. we need to get — increase our knowledge, in terms of the rate of infection in this age group, but also work with schools to be able to embed good health behaviours. the solution isn't solely in testing, it's in how testing is incorporated with other measures. already, some schools have been disrupted. for this head teacher, rapid test results mean keeping her school open. i love seeing children in school, and i love hearing them. i love hearing them learning, and so what i want is all the tools i can have to keep that going. i don't want to have to close the school, and i really don't want to have to ask children to learn from home again. research in schools across bristol will help everyone by mapping infections in one city. branwen jeffreys, bbc news, bristol. now on bbc news, this week the travel show looks back at some of their adventures in turkey, from the barber shops and bazaars of istanbul to exploring a dive site with a difference. coming up on this week's travel show, a short, sharp shock. painting the town to help change lives. the underground city that lay hidden for centuries. wow! look at that. and perhaps one of the strangest dive sites in the world. it is a wonderland down there! hello, and welcome to the travel show, with me, christa larwood. now, we are heading tentatively back out there on our travels, but we are taking baby steps. so this week will be taking a look back at some of our favourite stories from the past, hopefully inspiring some of your travel for the future. and this week where focusing on turkey, a country which over a0 million people had to last year. well, back in 2017 recent henry golding on his ever visit there, he kicked off his trip by heading to one of the most iconic and historic cities the world. here's how he got on. istanbul really is a city like no other. built on the banks of the mighty bosphorus straight, it was founded by the greeks, who named it by zaandaam. later the romans made it the capital of the eastern empire, changing its name to constantinople in honour of the emperor constantine. and for over 500 yea rs, constantine. and for over 500 years, it was the seat of power for the sultans who ruled the 0ttoman for the sultans who ruled the ottoman empire. built at the crossroads of europe and asia, it is turkey's largest and best—known city. so i've got in on the redeye flight, which is about 11 hours from singapore, but i've had a bit of arrest and now i'm ready to explore the city. so i'm going to meet up the city. so i'm going to meet up with a man called sedar it promises to take me around. hello! how are you? you must be sedar. good to meet you finally. thank you very much. so what have you got planned for me? i will have you exploring the city, i will take you to some of the major sites, try some different turkish foods. and also a hamam, which isa foods. and also a hamam, which is a turkish bath, but i don't know if you would like to start out with freshening up. know if you would like to start out with freshening uplj know if you would like to start out with freshening up. i think that might be good, i have a little bristle coming, five o'clock shadow. tucked down many sidestreets here in istanbul you'll find plenty of old school barbers like this one, where you can get a haircut or a traditional shave with a cutthroat razor and hot towels, all at a knockdown price. dating back to the days when many homes in istanbul had no running water, they are still popular with the locals, who come here to meet, socialise and freshen up. this is the bit i get a little bit worried about. the next. —— neck. now, this is something i haven't experienced. nostril haircut. so this is the way to ta ke haircut. so this is the way to take the little her, but he probably even can't see. —— little hair. he is burning the hair in the ears. i can smell! yes. how do i look? much better? brand—new man. as the centre of the ottoman empire for around 500 years, istanbul's wealth and influence grew and each new ruler or sultan was keen to leave his mark on the city. serdar has offered to show me perhaps one offered to show me perhaps one of the most impressive. this is the mosque of solomon. —— sulemain. sulemain was the 0ttoman emperor who ruled for a7 years. this is the biggest imperial mosque in istanbul. these mosques were financed by the sultan at the time. they are all built in seven years. this stands on the slopes of the hill, so from most parts of the hill, so from most parts of the city you can see this mosque. napoleon once said that if all the world were one country, then the city would be its capital. and running through the heart of istanbul is the mighty bosphorus. 0n through the heart of istanbul is the mighty bosphorus. on one side sits europe. 0n the other, asia. and thousands of years, it has carried cargo and passengers between the two and also served as a gateway between the black sea the mediterranean. making this one of the most important stretches of the most important stretches of water in the world. nice view, as well. yes! this is the spice market, built into 16th century, for the trading of spices. i can smell all of that spices. i can smell all of that spice india. it's making me a bit hungry, actually. well, i should introduce you may be to my friend here, my longtime friend. she has a food writer and she is going to introduce you to traditional turkish cheeses. perfect! i'll see you soon. this place is packed! it is amazing, yeah. always parked. well, look at that choice. and all of this is from turkey? these are all from turkey, they are from different regions under different cities and they all have different mixtures and different tastes. so, this is like our main sta ple so, this is like our main staple for breakfast. so this is our most favourite cheese. right. so breakfast cheese, i would imagine it being a little bit kind of lighter on the flavour, a bit easier? no, we never have liked flavours of jesus, no. never have liked flavours of jesus, no. totally wrong! -- cheeses. this next cheese actually reminds me of a parmesan or something like that. this one is made in july when we have the south—west wins. so it is like the milk. just little details, theyjust change the profiles. yeah, and this one is usually made around springtime. so they are made exactly the same but they have different texture, different taste. this is probably one of my favourites, actually. taste. this is probably one of my favourites, actuallylj mean, my favourites, actually.” mean, you should eat this with some crunchy bread. yeah, bit of olive oil. a little bit. some olives, perhaps? perhaps, why not, to metres even. when in rome! when in istanbul. istanbul, exactly. as my day comes to an end here in istanbul, serdar tells me that he's got one last treat in store for me. we are often one of the turkish bath saw hamams in the city. this is rather ground. first opened in the 16th century, it is built on a site that dates back to roman times. it is beautiful, but actually, the first thing you really notice is that thickness in the air. it is so humid in here. cold water! i've got what looks to be a pillow suck that is just filled with air and soapy water, and once you squeeze it out, these sods come out. i have enjoyed my day here in istanbul. its history, food and culture are remarkable. but for me, it is perhaps its location which makes it special. henry golding freshening up there in istanbul back in 2017. well, more recently, last year, mike corry headed south of the city to visit some of the coastal communities that have over the last 30 years become big tourist resorts. they still have one or two surprises up oui’ have one or two surprises up our sleeve. tu rkey‘s turkey's agn coast. it's where you'll find some of history's big hitters, ancient and evocative ruined settlements like pergamon and troy. and also here, the greek city of ephesus, which has been beautifully restored. here it is. the library of celsus. it was the third largest in the ancient world and the reading room had over 15,000 documents in it. it might look beautiful now, but until the 1970s it was just a pile of rubble. looking pretty good, right? we are hardly off the beaten track here. you may well recognise the names of some of the local towns. bodrum and marmara ‘s are now as well known for their holiday resorts as they are for the classical heritage. this is kusadasi, a little further up the coast, a package destination popular with northern europeans. walking around in kusadasi you can't help but notice that one of the hilltops is covering a rainbow. these are the rainbow houses, and we thought we would take a look. more than a00 of the homes here in this neighbourhood were colonised out —— last year as part of a project run by a paint company. it looks great from a distance, but it is also lots of fun close—up. high—5, high—5! yeah, yeah! the aim was that it would make the neighbourhood are much more liveable environment. these homes have been earmarked for demolition. we will be back with mike later in the programme when he had to dive site with a difference. —— heads to a dive site. i have not seen anything like that before. that is beautiful. and henry travels to central anatolia to look at a hidden city that was undiscovered for centuries before it was discovered purely by accident. wow! now partly because of its location, turkey has a fascinating history stretching back 1000 years ago for thousands of years and at the crossroads of europe and asia it has seen a long list of competing civilisations and empires pass through and all have left their mark in one way 01’ have left their mark in one way or another. back in 2017 we sent henry to central anatolia to go behind the scenes at excavations on a huge underground city that was stumbled on by a group of local construction workers purely by chance and what has been uncovered has been truly remarkable. in the heart of the town, among the modern houses and office buildings, workers made a startling finders they cleared a hillside for redevelopment. —— find as they. the largest underground city of its kind. experts estimate the caves could extend over a50,000 square metres. wow! look at all of this! ifind it square metres. wow! look at all of this! i find it quite square metres. wow! look at all of this! ifind it quite hard to believe that there were people living on top of here and all of this was actually hidden and so they had no idea that this was here. no. that is insane! what is all of this? this is a monastery. according to the scientists, the monastery dates back to the sixth century. a day. you can definitely see that outline. but cross there. —— that cross there. this region was very important for the early christians. because turkey is a single country on earth which has got the function of a bridge which is connecting two continents together, asia to europe, europe to asia. totally different civilisations, those other civilisations which leave some remains. —— those other civilisations. it is thought christian settlers used these caves 1500 years ago. the winding tunnels and hidden openings offered protection from attacking armies. starting with the early christian period, the enemies was roman empire. after six, seven century, the enemies was arab, persians and they were attacking often. and how they could fight against professional soldiers. tell me, i have noticed a couple of these around the caves themselves. what exactly is it? this is a stone door. this must weigh at least, how much do you think? around 1000 pounds. 500 kilograms. so it actually moves still? yes, look. wow! it is a little precarious. it isa it is a little bit steep, isn't it? yes. there are so many little holes you can actually just put your foot in and fall through but what is this area what is it used for? this area has been used as burial places, terms forfamily has been used as burial places, terms for family burial, chambers. the caves were not simply used for hiding. as well as burials, archaeologists believe the network was used to store produce and transport goods. these particular tunnels area bit goods. these particular tunnels are a bit of a tight squeeze. that is because they were a pa rt that is because they were a part of the underground water system and i think that they stayed for about 1200 kilometres but at the moment, they have only uncovered about 500 metres of it. and it is definitely not recommended if you are a little bit claustrophobic. luckily i am not. no—one is certain how long ago the first tunnels were built, it could be as much as 5000 years old, long before the christians settled here. only a small portion of the network has been excavated so far. and experts hope there are plenty more discoveries waiting to be unearthed. wow! look at that! i have actually heard of this spot because all of the archaeologists are very excited about this, aren't they? this is the church. an underground cave church. the frescoes are dating back to the 12th century. it kind of actually notice that these ones are pretty well—kept but a lot of them have kind of disintegrated away, some have fallen away from the actual ceiling. probably when we get to the other section of the search, over the that will be much better preserved because it is under the soil, it will be much better preserved than those ones. so this is going to take quite a long while because you need the specialists who will ta ke need the specialists who will take care and remove the dirt and hopefully finding some more fresh tunnels. henry uncovering turkey's long hidden past back in 2017. to end the show we are heading back to the aegean coast which has long been considered a holiday spot for sun and sea but beneath the waves, something you may not expect is providing a welcome home for local marine life, as mike found out when he went there last year. in 2016 authorities sunka last year. in 2016 authorities sunk a joint airbus jet just out here in the bay. they said it would attract divers and crucially, act as an artificial reef to house the wonderful marine life that lives here. three years later we are here to see if it worked. the project here was the first time a plane that big had been sunk for tourism purposes. butjust this year there has been a succession of similar ideas. tu rkey‘s succession of similar ideas. turkey's north—west coast and even bigger plane was lowered toa even bigger plane was lowered to a depth of 30 metres in june. bahrain submerged a 7a7 as part of wider plans to create an enormous underwater theme park. and injordan in theme park. and injordan in the red sea, they installed a military museum, comprising tanks, troop carriers and helicopter. all in battle formation. 0h, helicopter. all in battle formation. oh, yes please! ice cream! barash was one of the mastermind behind the plans here. are you all right? i would love one. what flavour? it was a complicated undertaking which began when the plane was split into five parts and driven here from istanbul. why did you choose this specific spot a disguised coastline? —— in this giant coastline. you probably cannot just you probably cannotjust think an aeroplane without preparing it first, right? —— sink. hey, guys! which one of you is thomas? here is thomas, how are you? we have a dive to do, yes. the wreck is close to the bay and the journey takes a few minutes, tomacz is my guide and he was also involved in getting it out to its final resting place. how many years have you seen the plane change? for yea rs, seen the plane change? for years, it is very rich here and we have many see bus, plane and there is a total sometimes, we see around the plane. and so in this big, vast ocean, why would fish come to live at the plane? because it is protection for them, like a house, and there is no dangerous things for their living because it is clea n, their living because it is clean, all clean. one, two, three. it is 18 metres down from the surface and immediately, i can see some of the changes i came here looking for. little sponges and coral are appearing on the side and schools of fish glide gently past. the sea currents have wrenched one of the wings free from the plane, providing more tempting knocks in which sea creatures can hide. but its former life has not been totally obliterated. there is just enough left to let you live out a few of your childhood dreams. i will! it isa it is a wonderland down there! yes, very good! quite a lot of fish! tickling side and underneath the wing. yes! what do you think the future is? the future will be very nice because it is already four yea rs past because it is already four years past and many fishes start to live in the air plane. under the wing there are many marine life, inside the cabin there are many marine life, see creatures. it is beautiful the way that the light came in the windows. with the fish, with a dolphin, corals and plants and animals growing on the whole itself. yes. i have not seen anything like that before, it was beautiful. awesome dive. thank you, good diving. that is all we have time for on this week's show and i hope you have enjoyed this look back at some of our past adventures and fingers crossed we will be travelling up there sometime soon. in the meantime, catch up with us next week, when: mike is in brazil two years after a catastrophic fire destroyed thousands of precious exhibits at one of the country's most famous museums. walking around you just feel hollow, like the remains of the museum.” you just feel hollow, like the remains of the museum. i will give a whistle and that is the signal to the penguins that they can come in. and lucy heads to london zoo to meet the volu nteers heads to london zoo to meet the volunteers who have given their time to help care for the animals during the corona crisis. i cannot say i have ever massaged a goat before but i think it is equally relaxing for them and me. so join us thenif for them and me. so join us then if you can but for now from me chrystal harwood and the rest of the travel show tea m the rest of the travel show team it is goodbye. hello. the weekend is upon us and the weather's looking a bit mixed. it's something of a north—south split. across much of england and wales, we've got a fairly decent weekend ahead. it's looking largely dry, pretty warm as well, with some sunshine on offer. but for scotland and for northern ireland, a different story. here, things will be turning increasingly windy, particularly through saturday, and there'll be some rain at times, heaviest for the north—west of scotland on sunday. but for the here and now, we've got this weak weather front here that's been slipping its way slowly south over the past 2a hours or so. but a more active weather front waiting out in the atlantic — that is what will bring the rain to the north—west. but for saturday morning, we've just got this band of cloud on this weak weather front pushing south. could be the odd spot of drizzle for southern england first thing, but that clears away. much of the uk looking dry with some long spells of sunshine, but there will be more of those blustery showers for scotland and for northern ireland, with more persistent rain arriving by the evening. temperatures on saturday somewhere between about 13—21 degrees. as we move through saturday evening and overnight, that's where we see that more persistent rain arriving across northern ireland and scotland, too, really heavy around those hills in the west in particular. whereas further south, you should stay dry overnight. and for all of us, it is going to be mild. for most places, temperatures are in the low teens to start sunday morning. now, through the day on sunday, high pressure sits to the south, keeping things settled, but we've got this weather front, this warm front, which is going to be quite slow—moving through the day. so on sunday, more heavy, persistent rain, which could lead to some flooding and disruption across the northern highlands in particular — we've got a weather warning in force for that. but elsewhere, a lot of dry weather. the best of the sunshine towards the south and east, where temperatures will be up to about 2a degrees on sunday. that warming trend is going to continue into the new working week, too. moving on into monday now, as that warm front pushes its way gradually further north, it is pulling in this warmer airfrom spain and france. so it is going to feel quite warm for many of us certainly on monday with long spells of sunshine. could be a bit more cloud and perhaps the odd shower along some northern and western part of the uk. most places are avoiding it, though. and in the sunshine, those temperatures in the south—east, 29, possibly 30 degrees, many of us in the low to the mid 20s on monday. stays warm to the middle part of the week, gradually things turn a bit cooler and fresher as we head towards the end of the coming week. bye— bye. good morning welcome to breakfast with naga munchetty and charlie stayt. 0ur headlines today: a sharp rise in coronavirus cases — the r number goes above one for the first time since march, with infections now doubling every 7—10 days. in birmingham and parts of the west midlands, more than 1.5 million people face stricter measures to contain the spread of the virus. dozens of people are missing as devastating wildfires spread across the us state of oregon. many more evacuation orders have been put in place, including right here, such that now more than half a million people in this state have been told to leave their homes.
