been watching these pictures for the last few minutes. this is a protest, a number of people gathering their from the main square in tel aviv to the defence ministry. holding up the signs of women hostages held in gaza. they are calling for their immediate release. we can hear the chanting there, and the posters in the pictures are just behind the camera's position there. is itjust turns around again, you can see that protest calling for the immediate return of the hostages. we will get more on the humanitarian situation in gaza. cancer patients say they're being denied exit for life—saving treatment through the rafah crossing to egypt, despite their names appearing on authorised evacuation lists. in parallel, fees charged by an egyptian company arranging evacuations from gaza have rocketed during the war, the bbc�*s lara elgebaly has the story, which was also produced by haya al badarneh. hopefully i will find my name there and be able to travel. god willing. translation: i'm on my way to the border crossing. - hopefully i will find my name there and be able to travel — god willing. this is sahem's third time at the border in as many months. she was being treated for leukaemia when the conflict began, leaving her and almost 10,000 other cancer patients in gaza without treatment. despite her name being on evacuation lists for the sick and the injured, she was turned away at the border. translation: i read that my name was published on the rafah - was published on the rafah coordination groups. my name was published on the departure list twice. i have been to the crossing point twice for no reason. i was turned away. sahem's name appeared on this list for evacuation to turkey on november 19th, but border agents on the palestinian side turned her away, saying the turkish envoy wasn't there to receive her. but we found that that wasn't the case. muna ashrafi was being treated for breast cancer and was on the same evacuation list as sahem. she was allowed to leave to turkey for treatment that day and was even able to bring her two daughters with her. translation: afteri got through the crossing - onto the egyptian side, i saw the turkish consul waiting for us and i knew i was going to turkey. we've spoken to two other cancer patients who say they've been turned away at the border despite their names being on evacuation lists. officials in turkey told the bbc that they are not involved in approving the exit of patients from gaza and that they are willing to treat as many patients as they receive. only 600 cancer patients from gaza have managed to leave since october 7th. israel vets who is allowed to leave gaza. the israeli ministry of defense told us they have no restrictions on the number of patients allowed to leave for medical treatment. palestinian border authorities declined to comment on sahem's case. but it seems there are other ways to leave gaza. a lucrative monopoly has emerged from the war, with one egyptian travelagency, hala, charging palestinians $5,000 per person to exit gaza within one to two weeks. this is more than four times the average annual salary in gaza. this man says he had to pay a hala employee an extra $300 to get his family on the evacuation list. we've hidden his identity. translation: they weren't letting anyone in. _ if you wanted to go in, - you had to pay to be let in so then you could pay the $5000. so then you could pay the $5,000. the fee was $5,000 for an adult and $2,500 for a child _ for palestinian passport—holders. he is one of ten people who told us they made extra payments of up to $4,000 to help employees to get their families evacuated. but it seems the best connected in gaza can leave without paying at all. we found the names of palestinian citizens on an evacuation list meant for egyptians. one of them told us they were helped to get on the list by someone with political connections. neither hala nor the egyptian foreign ministry responded to our questions. in gaza, time is running out for sahem, whose cancer is spreading. translation: we are suffering now. my medicine is finished. i'm so tired. i can hardly see in front of me. no blood tests or anything. my chemotherapy ran out a long time ago. without the money or connections many patients like sahem have been left behind. here in the uk, the children of some of the victims of the post office scandal are seeking compensation for the impact their parents' wrongful convictions have had on their lives. here's our business correspondent emma simpson. katie downey is stepping out to tell her story. her dad ended up bankrupt trying to make up for the huge shortfalls at its post office. nice to meet you finally. of course, i've met your dad. yes. she had an idyllic life until one day, they suddenly fled abroad. she only found out the truth six months ago. i wasn't able to say goodbye. i wasn't able to finish my sats in year 6, and ijust had to go to a country where i couldn't speak the language. for 15 years, i've blamed my parents, which really upsets me, and i feel guilty saying that now. but it's not the case, the post office did that to my family, and that's why our family unit was destroyed. she's formed a support group for the children of wronged postmasters. i met some of its first members. i'm so pleased to meet you all. millie castleton�*s dad featured in the itv drama. she's got her own awful story — bullied at school, ending up with an eating disorder. after my first year of uni, i had to drop out for a year because i was very, very sick. i had to go to hospital for about nearly a week because they were concerned about my heart failing. so, yeah... and eating disorders kind of, like, stick with you, so recovery was a very long process. today, others met for the first time on the bbc breakfast sofa. it's like i've known them forever, really, cos we have that same awful thing that �*s happened to us. that's happened to us. the group's called lost chances, and it's easy to see why. a lot of us have missed out on careers, we've missed out on education, and ultimately, our childhood we have missed out on. a lot of us worked when we were younger to be able to afford things that our friends did and we couldn't. katie's wasting no time. she's already had a reply from the boss of fujitsu. he hopes she can be included in a wider meeting with victims. but you would like them to offer some money, as well. yes, offer the financial redress that they've spoke about and other things they would possibly be able to offer us — education... counselling? counselling. it could be their best hope. compensation for family members would be a very unusual step. the law doesn't normally compensate for these kinds of losses, but this scandal is already breaking new legal ground, and this group's just getting going. emma simpson, bbc news, staffordshire. spacex has launched its starship rocket into space for his longest test yet, but the rocket was lost as it reentered earth's up was here. the government new objectives that'll eventually get us to that glorious, rapid, reusable future... twice before, starship blew upjust minutes after launch. was this going to be third time lucky? so far, so good. we are feeling the rumble. we are seeing 33 out of 33 raptor engines ignited. and now the critical part, where it blew up before — the successful separation of the upper and lower sections. 0k, we got a starship on its way to space and a booster on the way back to the gulf. oh, man, i need a moment to pick my ijaw up from the floor because these i these views are just stunning. and here's a view of the lower section falling back to earth. but then, communication is lost. and acquisition of signal, we'll see if we can get some other video... but back in space, it's all going fine, and the upper section begins reentry into the earth's atmosphere. this is where the earth's atmosphere is doing the work to slow us down. it's heat shield red—hot, until its signal is lost. its heat shield red—hot, until its signal is lost. again, this is the furthest and fastest that _ starship has ever flown. but overall, it's been a good day for the flight team. looks like success today. they haven't managed to bring the booster back, but that's, i think, a readily solvable problem with a few more trials. and it looks like the starship activities in orbit have gone very well. things keep going wrong because spacex is testing brand—new technologies, but each time, they get a little bit further. starship is absolutely enormous. it's 120 metres tall — that's nearly 400 feet. the rocket has two main parts. at the bottom is the super—heavy booster, which is incredibly powerful with its 33 engines. on top is a spacecraft, which can carry cargo or a crew of an astonishing 100 people. and what makes it really special is that in theory, both parts are reusable. the eventual aim is to build a spacecraft able to send astronauts back to the moon... ..and maybe one day take them to mars. pallab ghosh, bbc news. still to come. still to come on the world today — is it bye—bye bmi? research suggests there may be a

people and pacifists all over germany. they all moved here, and so they founded a creative scene here that was based for making this special culture flourished. when the wall fell down, the eastern

or bmi — is not as useful as measuring fat as waist—to—height ratio. one of our reporters was brave enough to explain how waist—to—height ratio works. take a look. the researchers focused primarily on the way we measure obesity in children. the university of bristol studied more than 7,200 nine—year—old children to reach theirfindings. one in three children in the uk are obese or overweight, according to nhs data. and as you can see in this graph, obesity rates rose sharply among ten and 11—year—olds in england during the covid pandemic and have not returned to pre—pandemic levels. professor andrew agbaje was the lead researcher for the university of bristol study. he explained why this alternative method of measuring obesity is better. we first appreciate the children of the �*90s who have provided this data for us. they have voluntarily undergone this research for the past 30 years. and we found out from their data that when we measure obesity in children, we are not measuring fat alone, we are also measuring muscle. and when we looked into metabolic outcomes, we realised we are not getting correctly what fat is supposed to be doing, as fat is bad. so simply because we are putting children on a weight scale. —— as if. so, our research tells us that bmi is not the best because it doesn't differentiate between muscle mass and fat mass. muscle mass is protective against so many diseases. but with bmi, we assume everybody�*s overweight or many children are obese. but with width—to—height ratio, we were surprised to discover that width—to—height ratio tells us about fat mass and not about muscle mass. i see. so, with that... so, just tojump in there, given that that's what you found, would like to see therefore the end of bmi, itjust not be used at all. of bmi, itjust not be used at all? i think that that time will eventually come, but at the moment, a real expressive usage of measuring tape can tell us a lot about fat. so, obesity should not be about weight, but about the fat itself, which is the problem. so bmi doesn't tell us so much about that. it tells us so much more about muscle mass because children have four times more muscle mass than they have for fat mass. so, in that sense, we need a width—to—height ratio, which a measuring tape so cheaply can get us, can give us such kind of nearly perfect result. for that reason, i would say that in our clinics, in the centre, we shouldn't diagnose children with bmi alone. at the moment, we need to add the width—to—height ratio to confirm if the weight ratios we are seeing is really due to fat mass. otherwise, we mayjust be misdiagnosing children. thinks to professor for the thinks to professorfor the most thinks to professor for the most of those of us who enjoy gardening are being urged to reassess our attitude toward slugs. the royal horticultural society and wildlife trucks or reminding us that slugs play an important part in reducing soil and much more. jonah fisher explains. they're so beautiful. that face, how can you not love them? could you learn to love slugs and snails? good job i had a shower this morning, isn't it? abby march certainly has. my favorite slug in particular would be the leopard slug. abby likes leopard slugs so much, she even dressed as one for a christmas party. that's her on the left. if you have a garden and you love your garden, you need slugs and snails. you need to get on board with loving slugs and snails. the wildlife trusts have joined up with the royal horticultural society to stress the positive things slugs and snails bring to gardens, like clearing up rotting rubbish and enriching the soil. the wildlife trusts have joined up with the royal horticultural society to stress the positive things slugs and snails bring to gardens, like clearing up rotting rubbish and enriching the soil. i have really grown to love them over the years. but what about all the damage they do, munching their way through plants and flowers? if you make your garden comfortable for slugs, you're making it comfortable for those natural enemies as well. so, if your garden's comfortable for slugs, it's comfortable for frogs, toads, thrushes. so there'll be a balance? there'll be a balance. it's working towards that balance in gardens. i went looking for gardeners to see what they make of the slug and snail rebrand. do you think you could learn to love the slug? with difficulty. i really can't stand the things. when they eat all my little plants, i'm not overly happy, you know? what do you do with slugs in your garden? throw them next door! jonah fisher, bbc news, in wisley. top work from jonah. too few to tel aviv with the protests going on. people are calling for the immediate release of hostages. we are keeping across these pictures on bbc news. analysis suggests patients of the worst performing hospitals are waiting four times longer than those of the best, and it comes at the figures at the end of january shows the waiting list has fallen. colchester hospital one of the first to offer this sort high—tech in the nhs — a robot in an operating theatre. colchester hospital one of the first to offer this sort of surgery to all patients. here, it's a hysterectomy. it's less invasive with speedier recovery times. using a surgical robot like this can mean operations are carried out more quickly. this patient may even get home on the same day, and that frees up more beds for others in the hospital who need them. surgeons say they're doing more operations and cutting waiting lists, but for the nhs as a whole, there's a huge task ahead. it's an enormous backlog, and it's making sure we have everything in place in terms of all teams working together, that we can maintain that speed of progress in reducing the longer waiting and then getting times back to what we feel acceptable. but it really is long—term planning going forward for that. yeah, ijust found that very, very hard to deal with... carol had to wait 2.5 years for major bowel surgery. after three cancellations, it's finally happened. i didn't trust anyone, and he even said, "we'll "we'll get you in next week." "0k, whatever, i've heard it all before." that's how you get, and it takes a massive impact on your life. it really, really does. do you feel relieved it now has been done? yeah, yeah, yeah. beds for patients needing operations can be hard to find if more emergency cases are coming into a&e. the ambulance crews are building up, people are trying to get _ into their gps, unable _ to see their gps, so the increasing pressure in a&e is getting greater. they're having to care for patients on trolleys in corridprs. on trolleys in corridors — safe, they say, but farfrom ideal. it means waits, which we really hate seeing, and we're forever apologetic for. but we just have to work with what we have, and that's what the staff will knuckle down to do. and they've been doing a good job this winter. finding space and then beds for those needing emergency care is difficult enough, so the task of cutting waiting lists for others doesn't get any easier. hugh pym, bbc news, colchester. will of the world's biggest music festival has been announced. let's take a listen. # i'll be the answer to your prayer # i'll be the answer to your prayer # iil— # i'll be the answer to your prayer # i'll give — # i'll be the answer to your prayer # i'll give it— # i'll be the answer to your prayer # i'll give it to you. #_ # i'll give it to you. # hotter than hell. , . ., # hotter than hell. dua lipa and sza talk to bill. they'll _ # hotter than hell. dua lipa and sza talk to bill. they'll be _ # hotter than hell. dua lipa and sza talk to bill. they'll be joined -
