hello, this is bbc news. the headlines: china, india, russia, brazil and south africa have warned against protectionism at the 620 summit in buenos aires. on the first of its two days, the summit has also been marked by disagreements over climate change, and there have been fears the leaders may not be able to agree on a final communique. a magnitude 7.0 earthquake has struck the alaskan city of anchorage. several large aftershocks prompted a tsunami warning to be issued, but that has now been lifted. reports from the area suggest the quake damaged buildings and roads. it's not yet clear if there are any casualities. britain and three american states have launched investigations into the hacking of marriott international, one of the world's largest hotel chains. the company said the hackers stole information about 500 million customers. names, mailing address, phone and passport numbers, and some credit card details were compromised. thousands of people in england are to be prescribed an ultra—low calorie, liquid only diet, after initial trials showed it can reverse type two diabetes in people who've

recently been diagnosed. nhs england says the diet will be used alongside an expanded programme that focuses on prevention. here's our health correspondent, dominic hughes. it's about cutting down. you know, small steps... at a community centre in leeds, the battle against diabetes is under way. reducing portion sizes and how frequent you have these naughty foods and all that. all the people here were on the cusp of developing type 2 diabetes. now they've been helped to lose a bit of weight and think about what they're eating. everybody should be educated about how we eat, what we eat, why we eat, and when we eat. i've lost so much weight. i feel better, i feel happier. an estimated 12.3 million people in the uk are at risk of developing type 2 diabetes. a quarter of a million people in england have already been referred to the special prevention programme,

like the one running in leeds. on average, they've lost nearly likg, so now the scheme is being extended. weight loss is all well and good, and we're delighted with the weight—loss trajectories that we've seen in participants on the programme. of course, what counts at the end of the day is whether we are preventing type 2 diabetes from arising. that takes a little longer. and a new pilot scheme will help those who've already developed type 2 diabetes. it will build on a recent trial of a very low—calorie diet that used liquid meals, and helped almost half of those involved to reverse the condition. a combination of diet and exercise helped labour's deputy leader tom watson shed seven stone and put his type 2 diabetes into remission. i did it because i didn't want to die, i wanted to live. i've got young kids, and so i did it to live for my children, really. and that was me finding my own way of doing it and that's what i would say to people, you need to do this for yourselves.

poor diet and weight gain is driving the growth and type 2 diabetes. the number living with the condition in the uk is approaching 4 million. it's a health crisis that campaigners say is beginning to be addressed. we need to take really, really rapid action, and this is why we at diabetes uk are delighted that nhs england has made this announcement today, notjust to think about prevention but also for those living with type 2 diabetes now, to think about the potential for them to put it into remission. improving the health of patients and saving the nhs money, the fight against the type 2 diabetes epidemic has just been stepped up. dominic hughes, bbc news. now on bbc news, searching for starlite. in1990, ini990, a in 1990, a remarkable material appeared on the bbc science and technology programme to my‘s world. i'm going to leave this taut body

and the state for a couple of minutes and it all to survive the inferno because it is coated with a remarkable new plastic. the substance appeared to have incredible heat resistant properties. the egg has not even begun to start cooking. its apparent uses begun to start cooking. its apparent uses the countless. it was better than anything else that i have seen. big industry was soon clamouring to discover more about this on the product. the material, christen starlite, was all the more miraculous because its creator, maurice ward, a ladies‘s hairdresser from the north of england had no formal chemistry training. one wonderful invention, it was not to being a sophisticated scientist.“ incredible that this material is painted on could be so powerful. despite huge interest in nasa, bowling and the ministry of defence, starlite never left the laboratory.

—— boeing. maurice ward died in 2011 without ever revealing the formula, but did starlite's secrets die with him. was starlite nothing more than an intriguing party trick, this a p pa re ntly an intriguing party trick, this apparently incredible material still save countless lives? —— awkward this. maurice ward and starlite first came to my attention back in june 2010. out of the blue, saying he had a solution that to the bp oil crisis in the gulf of mexico. i was in rookie reporter at the time covering local issues but there was something about maurice ward news story that really intrigued me. intrigued, as set out to meet him and find out more. graduate quite different to the normal sort of person. that product was starlite, material that looks and feels like a combination of metal and plastic, and says its creator, can withstand

75 nuclear blasts. we did it with an 999 75 nuclear blasts. we did it with an egg and tomorrow's world, it was that hot he could hardly pick it up with his bare hands. that of course created great deal of interest around the world. that will be mosul encounter with maurice ward. a left his workshop on the family farm wondering if his claims that about. there was this mysterious figure and harder to come to discover starlite? tell us about maurice ward, and your dad. what was he like? a very eccentric man, like his own way. had a mind of his own and nobody could tell him. a lot of people did not get on with him because i think the way he was. well, maurice was, of course it was a very elegant chap, whitehead, white eared, turned out nicely. i was very fond of maurice. he had congregated character, which was engaging to people like me. to some extent, he was an otherworldly

sort of character. at the short spells in the police and other chemical firm, spells in the police and other chemicalfirm, maurice opened a ladies‘s hair salon. chemicalfirm, maurice opened a ladies's hair salon. he started off in hairdressing, he was very successful. he did paul daniels's and lots of other people, travel the world. what colouring and permanent to the country in the sixties. maurice was a showman and he loved being the centre of attention. as a hairdresser, it is said maurice often referred to himself as maurice often referred to himself as maurice of paris. he was a hairdresser and he used to make his own wigs and because he is to do all the fibres for the heck, i think this is where the scientist at came in stock white maurice had an interest in chemicals and materials and tinkered in his makeshift lab but it is a tragic accident that would focus his mind. the worst british air disaster for 13 years. 3a people are killed at manchester airport, trapped in a burning plane. there is a big aviation disaster in manchester. a

lot of people were killed people died from fumes, not fire itself. and so, maurice was trying to come up and so, maurice was trying to come up witha and so, maurice was trying to come up with a product which would deal with that. he was burning rubbish in his back garden and he had not —— happened to notice that part of it did not burn, you just did not burn. so he tried to use torches and it still did not burn. so maurice essentially discovered starlite com pletely essentially discovered starlite completely by accident? he discovered a potential version of completely by accident, yes. maurice took his one material to the television programme, tomorrow's world. the broadcast was crucial in sparking the interest which quickly grew. this is the presenter who conducted the test. that is the old music that set the pulse racing. i was presenting the programme, which was presenting the programme, which was the bbc‘s flagship science

programme throughout the 80s really. and the day of the performance we would go through the script and we would go through the script and we would see how it turned out. it was with some trepidation that i went over there and gingerly fingered it to start with to see if i was going to start with to see if i was going to get scalded and listed as i picked this thing up, but to my amazement, it really was pretty cool amazement, it really was pretty cool. it was still warm it was not red hot like it had been a few moments before. —— blistered. saw the actual take, i was able go over to it with their confidence that i can actually pick it up straightaway that was not the case and the rehearsal, can assure you. the egg was raw inside. amazing. it wasjust jawdropping. maurice was very secretive sort of person. they said to him what is in this product? and he said had never told anybody yet andi he said had never told anybody yet and i am not likely tell you. —— i

have never. we have come to london today to meet with mark, he is a materials scientist and engineer at university college london. he is a bit professor of staff and he has got a bit of a history with starlite. he has done tests on in the past and we are going to ask him what properties starlite has that makes it so resistant to extreme heat. yeah, here we go. in 2012, maurice's daughters brought starlite to mark‘s lab. maurice's daughters brought starlite to mark's lab. this is an exciting moment, my virtual test of starlite in my own lab. wejust did not know what to expect. what is starlite? sta rlite what to expect. what is starlite? starlite is a painter, like a white, viscous liquid. 0nce starlite is a painter, like a white, viscous liquid. once it is set hard, if you apply heat and we applied blowtorch to it, the material itself chars and becomes carbon and that,

it then becomes this expanding foam of carbon. now, carbon is very high melting point material, it is incredibly thermally resistant and so incredibly thermally resistant and so you have this very low density foam, made a very high temperature resista nt foam, made a very high temperature resistant material copper it very quickly. so it is a kind of magic and serial, it is a thin paint then it becomes a thick, chunky, insulated material. —— and it happens very quickly. material that can withstand a blowtorch for that length of that is an impressive material. maurice's masterstroke are taking starlite soon attracted the attention of the military and governments. the ministry of defence $0011 governments. the ministry of defence soon convince the programme to allow them to run a series of test. one of them to run a series of test. one of the nice things about being in science, you often in fact go down oi'i science, you often in fact go down on the beach to look at rocks and then something is underneath those rocks that is quite, quite

different. starlite rocks that is quite, quite different. sta rlite was rocks that is quite, quite different. starlite was very, very different. starlite was very, very different. i was the kind of guy, i guess, that they used to come to an ask how does this work? what makes it tick, as it were. keith was particularly interested in how sta rlite particularly interested in how starlite will perform against high—powered lasers. starlite will perform against high-powered lasers. what was interesting was it changed only down to the depth that it needed to to deal with the heat polls that was put on it. the heat pulse —— the bigot heat pulse, the better starlite worked. initially, he wanted to come in and the there while tests were in fact done. later on, he gave me samples, which in fa ct left on, he gave me samples, which in fact left in my care, provided i could take them back to him afterwards. he knew that i did not actually analyse. the ministry of defence test results showed sta rlite was something they had not seen before and now nato was also interested. it wanted to know of sta rlite interested. it wanted to know of starlite could interested. it wanted to know of

sta rlite could withstand interested. it wanted to know of starlite could withstand a nuclear explosion. the tests were carried out at the atomic weapons establishment in the uk, and the white sands missile range in new mexico. some of the tests that were done used for kilotonnes simulant. was a nuclear blast resistant?“ thermal blast resistant. it does not get torn to bits. how serious was the mod about starlite? get torn to bits. how serious was the mod about starlite ?|j get torn to bits. how serious was the mod about starlite? i think when you are the time it was a game changer overall in the test that i in fact changer overall in the test that i infact did, changer overall in the test that i in fact did, that it was better than in fact did, that it was better than in fact anything else that i had in fa ct in fact anything else that i had in fact seen. starlite had great potential. government agencies and businesses were queueing up to work with maurice, but would he be willing to share his secret with them? maurice had produced a material that appeared to have numerous applications, military, industry, even space travel all

possibilities. why are, why have we not heard more of this so—called miraculous substance ? not heard more of this so—called miraculous substance? is a very different skill sets, inventing material or in fact, accidentally inventing material and building a business out of it. those are in the sense two completely different things and i think he either could not be the second thing, or he did not be the second thing, or he did not have someone around to be trusted to do the second thing. and so, it became just a curiosity, this material, because it never made the leap into a commercial material. material, because it never made the leap into a commercial materiallj have brought you. ok. talk to the attorneys. the we have got to have the agreements in place. yes. all we're saying really is i am protecting my material. and you are trying to pinch it. that's right. was also reluctant to tell people

what was actually in starlite. because they wanted to sell it and if he had given them the information, he would have no protection. they could just say well, they manufactured it, they invented it. he is to play mind games of people. is that different bits of ingredients laid around, but it would not be the proper stuff because he did not trust anyone. trust was a huge stumbling block? he wa nted trust was a huge stumbling block? he wanted to help people, but he wanted the control is well. i think he was out of his depth. i think he had something there that could easily have big, very, very big. he was could easily have big, very, very big. he was being could easily have big, very, very big. he was being very could easily have big, very, very big. he was being very cautious about what happens when you actually publish... if i had about what happens when you actually publish... ifi had gone about what happens when you actually publish... if i had gone that route, then the next thing is it is published, and for the appropriate fee anybody in the world could buy a copy of the patent, and the

unscrupulous ones would try and copy and imitate it and it has to be fully set out, it is not something where you just sketches, it has to be fully set out, and anybody with an average intelligence would be able to reproduce. radu had a problem. his material was worthless without identifying a clear use for it -- without identifying a clear use for it —— maurice. if he wanted to capitalise on his invention he would have to die of was in it. there are thousands of the sample is in it. most of not out there. they haven't found that place in the world yet. we have magnetic liquids, we have metal alloys, they haven't quite made it into our lives because they don't quite actually do something we all need or want to pay for. that's not to say they won't in the future. his end goal was in fact to get something like £10 billion on him so he could just do it. no one is going to do that.

i thought you said billion, he wa nted i thought you said billion, he wanted 10 billion? i did. he was stubborn like that. maurice's nature is illustrated in this bbc documentary. here his daughter response to an off—the—cuff comment from the programme makers. response to an off—the—cuff comment from the programme makerslj response to an off—the—cuff comment from the programme makers. i would try and sell it out for the best deal i could get for it by contacting all the people who have been interested in starlite and up until now. how would you deal with them, how would you do that? being back have been in all these high—powered meetings and seen all these executives how they try and deal with it. i would have these executives how they try and dealwith it. i would have to make sure i was paid fully for it before they got anything. before they got any formulation. money through the bank, before they got anything. that

sounds interesting, what would you do with £2 million? it would be better than nothing. not as good as ten! you haven't got ten yet. he was a very controlling, argumentative person. but that is who he is. if he wasn't the eccentric person he would never have invented it. he was a showman, that is a very important pa rt showman, that is a very important part of any business that you try and grow, you invent something and then you have to get people on board. all these investors, they have many different ways to spend their money, and your material, you have to convince them that your material is the best way to spend the money. you need of art oh, you need a demo and he had demos like surely the best demo ever for a new material. i can't think of a better one. he invented something, he had that mind, he had the ability to show it off and get people really excited about it. ijust don't think

he had the business head and to have all those in one person, that usually doesn't happen. maurice passed away in 2011. some believe he took the secret of starlite to the grave. that hasn't determined —— deterred others from trying to replicate it. the truth about starlite is that it is something that you could potentially... knock up using a product you can get in your own home. you yourself has made a batch of starlite? i have made a batch of not what i would call starlite, but i have knocked up something. it is getting red hot in the middle, and notice i am still holding this metal plate. there is no gas produced,

when i take it away... it is warm isn't it, but it is not red hot by any stretch. this is made using regular household products. do me a favour, would you feed those...|j favour, would you feed those...” fed them yesterday. maurice's plans would have been based on what he had and his home during that time. he would have said, in my home i have this and that. if i do this and that, what does that lead to? does it lead to anything novel? what would he addressed a habit home, he would he addressed a habit home, he would have head gel —— what would a hairdresser have at home, he would have head gel is, moose, hairspray, are we close? did he make... i

believe he did. he would have had glue. you think that is what he used? it glue. you think that is what he used ? it is glue. you think that is what he used? it is white, so it could have been something as simple as pva glue? i'm not going to go down that path. but if you look at published papers, people have used pva glue for these kind of applications. what is in sta rlite? for these kind of applications. what is in starlite? can't tell you that. not one ingredient? no. is there pva glue in its? can't tell you that. you have the formula for it which you add passed on to you. just tell us you add passed on to you. just tell us where you are up to with that and what you want to try and do with starlite? we do want to bring it to the open market. you should be able to buy it on a shelf. this is what we tried to do, would it into paint so we tried to do, would it into paint so people can paint their own houses. first off let me say we are

pleased to see the bbc taking up the story of maurice, who is an amazing seasonis story of maurice, who is an amazing season is —— genius became groundbreaking research. we third -- we had about a us company through keith lewis. 0ne we had about a us company through keith lewis. one of the partners in that firm contacted maurice in 2008 and bought the intellectual lights to sta rlite and bought the intellectual lights to starlite in october 20 and bought the intellectual lights to starlite in 0ctober2013. that included notes, test reports and sample is from the boeing and white sands test. we have been in touch with the company and he declined an interview, saying the company was keeping a low profile until they are ready to loss of. he did send us a video statement and some footage from their very own a test. we produced sample is, we built a high—powered laser attacks at power densities far exceeding prior laser testing. also an 18—year—old legacy sample from the boeing tests, sukhoi

—— sustained equivalent laser attacks without a mark, proving... steve talks about how they are looking to use starlite for very similar applications as those identified by maurice, nicky and others. in america you have a company called thermashield that your mother and another sister sold them a formula. that formula is not as good as what we have got. you are saying you have some sort of superstrength sta rlite? saying you have some sort of superstrength starlite? yes. it is not about having it and putting it all together, you have to put it together in certain stages. and if you don't know how to do that it won't work. there are now many, many of these patents out there —— paints out there, if you look at them on the internet you will see a lot of companies making a lot of money is out of this. starlite already exists, not as a named brand but as a commercial entity, that paint exists. there are other paints

similarto exists. there are other paints similar to starlite on the market, that people can go into shops and buy it. why would they go in and buy sta rlite buy it. why would they go in and buy starlite as opposed to one of those? because starlite will save your life. i know there is nobody else out there who has a formula like starlite. despite nicky's claims, herformula is yet starlite. despite nicky's claims, her formula is yet to make starlite. despite nicky's claims, herformula is yet to make it starlite. despite nicky's claims, her formula is yet to make it to the market. do you think you could ever get to the point where we can go to a shop and buy starlite? it would have to be a lot better than the competition. for that business to grow in my view. you need proper tests to be able to define that will stop if they can prove that they are going to do really well and i would really be cheering, i am cheering for them that that happens.” really be cheering, i am cheering for them that that happens. i had not heard of anything which has been, which is so momentous in it application, and i think i would have done, i think we all would have done if it was out there. these days what people do is open source convention and get the rest of the world to innovate around it.”

convention and get the rest of the world to innovate around it. i think it would be a great legacy for maurice if the invention was open source and everyone could play around with it. as we have followed the story of starlite we found it impossible to separate it from the story of its enigmatic creator. we have heard accounts of maurice's ingenuity and showmanship. we have also learnt of his stubbornness and frustrations of those who tried to work with them. so how should we remember maurice? the person who spots the new material at that moment of an accident may be, or because he is doing some experiments, is a special person. and it is sad to me that that moment for maurice did not end up with sta rlite for maurice did not end up with starlite in our lives, and i think it could have. if you take all the materials away from the world, all this stuff around us, we are just naked animals. the invention of materials and creating civilisation, thatis materials and creating civilisation, that is what we do as humans. so he

was, he was as good as any on that front. in a way that best thing about starlite is the story itself of maurice. his story tells you that it is possible to do something very novel, very new in your own barrage, and the fact that anyone can invent something that could change the world. —— garaged. looking ahead to the all—important weekend weather prospects and it is going to be one of those weekends where there will be quite a bit of rain around, we will all see some wet weather at some point but choose your moments, there will be some dry spots as well. often the weather will stay pretty cloudy. 0n the satellite, racing towards our shores is another area of low pressure which will be bringing the wet weather and indeed we have already seen over the past few hours the rain arriving across wales and the

west of england, which will continue pushing eastwards over the next few hours with showers continuing in the north and west of scotland. if you are planning to head outside of the next few hours it will be quite chilly, there will be a few patches of frost in the countryside, some of the deeper valleys. for saturday morning we are looking at a cloudy and wet one across south england but the rain will be quite heavy first thing in the morning as well. as we travel northwards the rain gets lighter across wales and the midlands, perhaps a dry start for north—east england but the cloud quickly spreading and rain for northern ireland. a chilly start of the day in scotland, showers continuing to affect northern and western areas. through the rest of saturday our first band of rain will continue to push its way eastwards, rain will be quite heavy for a time. even as it clears there will be quite a bit of cloud, the sky only slowly brightening with a bit of sunshine

coming through later. the best of the weather for north—east scotland, that is where we will see the driest conditions, northern ireland not having a bad afternoon. saturday night sees another pulse of rain moving in, northern ireland, wales, west of england, that will push into east anglia and south—east england overnight, that looks to be quite heavy, this band of rain is pushing further northwards, getting into scotland. the far north—east may hang onto some cold air to start the day on sunday. sunday quite complicated weather picture with a couple of centres of low pressure around about the uk and lots of weather fronts too. these weather fronts will continue to bring outbreaks of rain, possibly the wettest weather across northern england and scotland, the early—morning rain clearing away from east anglia and south—east england, but showers will move in from the west, perhaps some lengthy spells of rain for northern ireland, wales and western areas of england. mild, 15 for south—east england, cloudy skies across scotland, temperatures close to average for this time of year. into the forecast next week

it is staying pretty unsettled, the weather is a chance of getting cooler and colder in scotland. welcome to bbc news, broadcasting to viewers in north america and around the globe. my name is ben bland. our top stories: world leaders gather in buenos aires for the g20 summit, but there is tension over trade, climate change and the situation in ukraine. a 7.0—magnitude earthquake hits alaska, near the city of anchorage, causing widespread damage hello and welcome to bbc news. as the g20 summit begins

in buenos aires, the prospects for warm discussions between the world's leaders are looking unlikely. russia's naval clash with ukraine is causing friction,
