Now on bbc news, click. This week, lara is feeling the pressure. In her eyes. And if those eyes are feeling the cold, how about some anti fog sunglasses . Talking of headwear, heres a 3d Printerfit for a queen. And when is Elephant Ivory not from an elephant . When its from a 10,000 year old fossil. Chris has the tech to tell the difference. If you were just handed that, could you tell . No. Not immediately. Yep. Its going to be a mammoth show. Martin those of us who wear glasses know exactly how annoying it can be when they fog up. Everything goes somewhere. So here comes the technical bit. Condensation occurs when Water Vapour from your sweat, breath or the environment around you lands on a cold surface. As it cools, it changes into tiny drops of liquid, forming a film that looks a bit like fog. So how do you stop this . You could use a spray or a lens cloth. This could help for a little while, but what if there was a more permanent solution . Lenses are relatively cool compared to your breath, especially when the outside air is cold. So in order to see things properly, we need to go outside. Were heading to the stunning alps to meet the team from Eth Zurich to get hands on with their glasses. This solar powered innovation aims to end fogged up lenses. 0k. And were here to see it in action. Traditionally, surfaces are coated with water attracting molecules, which attracts an even spread of condensation. This is how regular anti fogging systems work. This new method heats the surface, preventing condensation from humidity forming in the first Place. 50 of the sunlight is invisible, and were not seeing it with our Human Eye its in the infrared and we design a coating that absorbs this infrared energy, heats up the surface, and thereby can prevent fog. And the whole Mission Or Vision behind our coating is actually to make something thats durable and in comparison to existing anti fog solutions, which you always have to, you know, reapply, you use your plastic bottles, and we provide a durable one Shot Solution that lasts forever. So this coating absorbs radiation, but how do you ensure that its absorbing enough radiation but not too much heat where its impractical . Yeah, its a subtle balance. Obviously the energy is limited to a certain extent, so you cannot heat up to 100 degrees celsius, but we can tune actually how much infrared our coating absorbs and thereby also change the effect on the temperature. The coating is extremely thin, it stays perfectly clear, but, behind the scenes, its busy warming up to block fog. No fog no fuss. But how does it work, you ask . Well, its all in the layers. Now, picture this coating as a burger. The patty in the middle contains gold and has the importantjob of soaking up all that radiation. The bun around it boosts the absorption, keeping the precious metal safe from wearing out. Tasty, right . Maybe we should have made burgers rather than muffins. Oh, well. We are also looking into the Car Sector because, you know, on the one hand, you have the windshields that fog up and it always takes a while until they defog, but then you also have sensors like Radar Systems or also in medical devices, when you have a Human Breath that, you know, can deteriorate a signal. This sunlight powered coating could change the way we see things, quite literally. So could this be the Solution Weve been waiting for . The future could look a whole lot clearer, powered by a little bit of sunshine and a dash of gold. Lara wearables have been trying to help us be our best selves for years. Now, though, it might be time to dig deeper. Not my usual attire. Now, Theres Plenty of technology out there to help us track our health but, with an increasing focus on ways to either prevent disease or at least identify it early, ive come to visit one company thats hoping to provide low cost scans so instead of the thousands of pounds that they can cost, a full body once over forjust a few hundred quid. But how useful are they . Neko health was co founded by spotify founder Daniel Ek so, unsurprisingly, has tech at its core. All right. So first well be starting with the body scanner. This wasnt what i was expecting. It looks more like a dance floor. This wall of cameras is responsible for over 2,000 2d And 3d images, so it will be able to map all of the moles and lesions you may have on your body. And the Ai System will flag anything of interest, alongside an actual doctor checking. The scan is also looking for inflammation with its thermal imaging cameras. Were trying to bring in 21st Century Technology and use data to create a very personalised health experience. And who better to sort of guide us through that than daniel, whos done exactly that, but for music . Robe back on that was bright, and quick. Then bloods are taken and zoomed off in a tube. Eye pressure is checked along with Blood Pressure and Grip Strength, which they consider a marker of how youre expected to recover from serious disease. Great. Then there were a load of cardiovascular checks, an ecg, plus some fancy machines that we werent allowed to film in action. We want to get as much high Quality Health Information out in the shortest amount of time possible, in the cheapest way possible. So we use any technology we can find to deliver that. So thats the laser radar machine. Ill be pinpointing these Laser Signals at different parts of your body to measure something called a pulse wave velocity, and it will help us have a better look at your cardiovascular health. And last but not least, weve got the tissue scanner. So this will help us have a better look at your metabolism and your microcirculation beneath your skin by using light waves in different frequencies and wavelengths. Hi, lara. Hello. Come on back in. Then you meet the doctor, in a pod, who presents you with a lot of data, advice, and your avatar. Apart from my Grip Strength needing some work, i had a screen of optimal readings. Then came a good nose inside my veins. And hearing this. Heartbeat. Sounds like thunder its a nice, strong, healthy heart sound. There are specialists and further tests available on site for anything that needs escalating. I wondered how often that might happen. We went through all of the scans that we did in our first year in sweden and we published all of our outcomes, and what we found was that for about 1 in 100, so 1 , they had an immediately life threatening condition that they were unaware of. For about 10 , they had something seriously going on that was undiagnosed, and we helped them get the appropriate care as well. And for about 80 85 , they were in good health. Medics are increasingly embracing prevention, but some dont feel that availability of full Body Scans not neko specifically, but any are the best solution. You cant go what i call fishing, which isjust put somebody through a Machine And Hope for the best. You have to be looking forsomething, looking for a disease thats important. What happens is you pick up coincidental findings that are normal, but you end up having more tests and more tests. I think what we should be promoting isnt these scans, but is actually people getting wearables to start understanding their body indices. The traditional medicine would say, oh, if someone is healthy, its unnecessary that were checking things. And we kind of think the opposite, that helping these people stay healthy, thats actually the most important thing for the future. This fusion of ai, tech and Human Doctors appeared to do the bits that it did well. But on the Flip Side of overdiagnosis, how about what it cant see . Digestive issues, womens health, maybe other cancers. Warning signs might show up in Blood Tests or be raised in a consultation, but amidst what aims to be a comprehensive once over, there are still limitations. Spencer 0k, time for a look at this Weeks Tech News now. Ai assistants with really good long Term Memory are about a year away, according to Microsofts Head of ai mustafa suleyman. He said products which can recall conversations, projects and problems will encourage users to invest more time, and share more of their personal history with them. Some critics have concerns about this level of integration including privacy, and the possibility of the Ai Tools giving wrong information, or displaying in built bias towards the user. Scientists at the University Of Montreal have found new ways to help cats suffering from chronic pain. Instead of having to sedate the felines, theyve been able to scan their brains while theyre awake using electrodes hidden under specially knitted hats. In the past, the cats tended to shake off or chew the wired electrodes used in testing well, theyre cats, thats what they do but now, the cats in hats are cute and cosy. And its happy birthday to comic sans. Yeah, love it or hate it, this font has been around for 30 years it was originally designed as part of Microsoft Bob a piece of software designed to make windows more user friendly. It was released in 1994 and, unbelievably, its still around today. Chris a dead sumatran elephant, its tusks removed. Poachers are suspected. To protect elephants, the Transnational Trade In Modern Ivory is banned by international convention. But tusks of the type seen in this footage from russia in 2016 arent prohibited. Thats because theyve come from the elephant� s extinct Ice Age relative, the mammoth. Tonnes of ancient tusks are extracted from the frozen ground every year, but telling the difference between legal Mammoth Ivory and illegal Elephant Ivory is a real problem for Border Security, and is even a challenge for mammoth experts at the natural History Museum in london. Hi, adrian, lovely to see you. Very nice to meet you. In his office, Professor Lister had gathered together lots of examples of Mammoth Ivory. What is a mammoth . Well, a mammoth was a species of elephant. They were actually quite closely related to the living elephants, but the mammoth was a species of elephant adapted to the cold conditions of the Ice Age, and they had a huge distribution. Its been estimated that there were probably as many as 10 Million mammoths at their peak. How hard is it to tell the difference between Mammoth Ivory and Elephant Ivory . Once a piece has been carved, like this little mammoth model, which is made of Mammoth Ivory. Actually, i know that because i bought this at a mammoth Ivory Shop in alaska where they dig up the tusks. However, if i didnt know that, i couldnt tell. Ive been working on mammoths, you know, for decades, and elephants. But you cant really tell whether that is mammoth or Elephant Ivory. The only way you could tell would be to actually take a piece of this and submit it either for radiocarbon dating, because a mammoth would be Tens Of Thousands of years old, or dna analysis. But first of all, thats destructive of the specimen, secondly, its expensive and would take time weeks before you got the result. And if youre a Border Security guard, you know, trying to stop the trade in illegal Elephant Ivory, a tough job to try and tell the two apart. Yes. I mean, you cant do it. You couldnt, really. Theres not really any way of knowing. I mean, weve got a piece of Elephant Ivory here. How easy would it be to disguise this as Mammoth Ivory . Very, very easy. You see this piece of Elephant Ivory thats been in the museum for years. Heres an equivalent Tusk Tip from a mammoth, and all you would have to do would be to stain this a brown colour and you couldnt tell the difference. So this is a school of anatomy. Youd never guess, would you . Laughter. At bristol university, dr rebecca shepherd, with help from Professor Lister and others, has found a quick way to tell different types of ivory apart using lasers. Theres a piece of equipment at airports around the world called a raman spectrometer, and this is already used in the identification of materials for things like drugs and unidentified liquids, so were trying to repurpose this to tell the difference between elephant and Mammoth Ivory. Essentially, it shines a laser at a sample, and the way that laser bounces back to the detector can tell you really detailed information about what a material is made of. There are people running legitimate businesses carving Mammoth Ivory, and presumably your technique will be useful for them because it gives them a way of proving, look, this is legal Mammoth Ivory. Absolutely. It can be used tojust prove that a sample is what it says it is. Is there a lot of interest from Law Enforcement in this new technique . There is. Ive been talking to people within Border Force in the uk and the Uk Wildlife crime agency, and there is potential use for this in Law Enforcement in the uk. Youre also thinking about different types of things that you could identify using this tech. I had a really interesting conversation with somebody from Homeland Security recently who said that its a bit of a problem people trying to smuggle eggs of endangered bird species across the border from mexico. So the next Project Id like to get started is to see if we can tell the difference between eggs of different species. Since she published her results, Dr Shepherds work has attracted international interest. So, im currently in hong kong, and im here to present my research at a workshop thats designed to get together people involved in preventing wildlife crime from across all of asia. So theres people from wwf, people from Border Force, people from Homeland Security, and everyone with an interest in wildlife crime. Well, the mammoths are extinct, helped on their way by human beings. Some people fear elephants might go the same way. Mammoths only went extinct 4,000 years ago and we think that the reason for that was a kind of Double Whammy of Climate Change that was happening at that time and hunting by people. And when we look at modern elephants, they are faced by the same combination of factors. So the mammoth, if you like, is a kind of a lesson from the past that if we dont do something about it, the living elephants may go the same way. I have seen gods fly. Spencer in the heart of africa lies the top secret, high Tech Nation of wakanda, the setting for marvel� s two iconic Black Panther Movies and ruled over by angela bassett� s queen ramonda. My son, it is your time. Much of the movie was created using suitably advanced technology, and that includes the queens wardrobe, the most elaborate parts of which her Crown And Neckwear were 3d printed. With the 3d Printing technique, you can create more complex geometries, more innovative designs, and also in a more sustainable way. Julia koerner is an austrian Designer And Architect who specialises in 3d Printing high fashion pieces and products, couture dresses, bags, accessories and ornaments. But it was queen ramondas Fabulous Attire that caught our eye and also those of the 0scarsjudges. Both Black Panther films won their costume designer, ruth e carter, academy awards. The Design Process for Black Panther was looking at the traditional zulu patterns, which traditional African Women would wear and taking those african patterns and digitising them in the computer to represent the regal attire of the queen. There are many different 3d Printing techniques, and the crown was created using something called laser sintering, where lasers melt together particular parts of a box of powder, leaving the rest as dust. The End Product is then dug out and the remaining powder reused. One of the great things about it is that you can realise very filigreed, very fine structures which you cannot make with any other technology. How did you get involved with Black Panther, and did you even know who you were working for . At the beginning, i didnt know who i was working for. I started the Design Process, then the actress was cast. I literally put into google, angela bassett, film star, film technology, and then realised it was for marvel and Black Panther. So thats how you found out who you were working for . Exactly. When i first time watched the film, i think one of the most overwhelming things was to actually see the work on the big screen, to see how many people in the world were able to see this. And i had friends come to me and say, julia, ifinally know what youre actually doing over the years, julia has collaborated with several haute couture houses. Her designs are unique, inspired by nature, with a focus on using sustainable materials in the 3d Printing process. A prime example of this isjulias setaejacket, which was shown in Philadelphias Museum of art. I was inspired by the madagascan sunset butterfly moth, because it has thousands of different colours in its wing, and it was the firstjacket made in this technique that a printer, like in an ink jet Printing Process, puts the Material Layer by layer onto the jacket. Because its printed in little dots and points, theres a certain flexibility which stays within the fabric. 3d Printing is a technology which seems to be finding its Place at either end but not the middle of the market amongst those who need expensive bespoke items, and the hobbyists. Cue toybox. We make it accessible. If you remember, like, eight years ago, everyone was telling you that 3d Printing was going to take over the world. Yeah. And it didnt. And the reason it didnt is cos its really difficult to do. And thats why the founders of this company created toybox. What differentiates this printer is all of the technical stuff, the mumbojumbo behind the scenes, all of that is done for you and you just press print. Toybox is a small, personal 3d Printer thats trying to ahem break the mould. Its connected to an app with 15,000 designs to choose from, many of which are free. The Printing Process can take anything from six minutes to several hours, depending on the complexity of the design and the resolution the number of lines per centimetre that youre happy to print at. This little chap took nine minutes. Its a little cat. And its amazing how intricate you can get. One of the things thats always intrigued me about 3d Printing is the idea that you can create objects that it would be impossible to manufacture in any other way, cos theyre so complex and weird and theyve got bits inside and outside other bits. Now you can also make things which are flexible, but you can print them all in one go. So this comes out of the printer as a oner and then you just give the joints a little wiggle and it snaps the little supporting struts between each one, and you get something bendy like this hammerhead shark. Multicoloured toys are printed in their constituent coloured components and then snapped together afterwards. But Hang On how do you preventjust anyone from churning out loads of these copyrighted toys without permission . So, lets say you were to going to print spongebob� s head. So, lets say you were to go to print spongebob� s head. You would press spongebob� s head, it would send a message up to The Cloud, The Cloud would encrypt that file and send it directly to your printer to only print once. So it never hits your phone, your computer, or your tablet it only goes to your printer and its only encrypted to work on your printer once. But heres a question thats always bothered me arent 3d Printed Objects always going to be more expensive to make than those identical, mass produced, Injection Moulded Items that were all used to . Well, Julia Koerner has a thought on that, too. I think in todays time, where we focus on Personalisation And Mass customisation, the 3d Printing technology brings advantages in these aspects where you can have your unique design personalised in your unique colour, maybe with your initials designed into it. Also, i think in todays time, do we really need to produce A Million pieces where we end up not knowing if we actually will sell those . It is an interesting thought, isnt it . But if 3d Printing is to be a sustainable alternative to mass production, if we really want to reap the benefits of this technology, well, we do have to be able to afford it. Anyway, thats it from us for this week. Thank you very much for watching and we will see you soon. Hello. A Weather Front is approaching us, and that does mean a lot of cloud for many of us on sunday. Quite a few showers too, some of them will be heavy, but i think early in the morning, if youre closer to the North Sea coast, therell be some sunshine. Lets have a look at the satellite picture. Heres the Jet Stream pushing the Weather Front towards us, and that Weather Front brought a spell of very wet weather Saturday Evening for cornwall and devon. But i want to talk about the next few days and highlight this feature here. This Dartboard Low coming out of the tropics thats actually a hurricane which will transition into an extratropical Weather System or a mid latitude Weather System. And look at it. If you eyeball it, its ominously heading in our direction or is it . Well, actually, theres a lot of uncertainty. It could go to the south of us, taking its very strong winds and rain. It could just about clip us. And it looks as though midweek and it looks as though midweek we could see some potentially we could see some potentially bad weather across the south of the uk. Bad weather across the south of the uk. But its still some days away but its still some days away and theres really a lot and theres really a lot of uncertainty with of uncertainty with this Weather System. This Weather System. So keep track of the weather forecast. So keep track of the weather forecast. Now, heres the here and now, now, heres the here and now, or sunday morning, or sunday morning, temperatures hovering temperatures hovering around 10 degrees, around 10 degrees, so its not too cold first thing. So its not too cold first thing. And rather a lot of cloud and rather a lot of cloud with this Weather Front with this Weather Front sweeping off the atlantic, sweeping off the atlantic, remember, pushed remember, pushed by that Jet Stream. By that Jet Stream. A lot of showers through a lot of showers through the morning and lunchtime the morning and lunchtime across western areas, across western areas, around the irish sea, into northern ireland. Around the irish sea, into northern ireland. Again, the further east you are, so closer to that North Sea coast, the drier it will be. There might be some sunshine around. But i want to show you whats going to happen later on Sunday Afternoon and evening. The showers in the south really could be quite heavy, downpours moving through parts of wales, into the midlands and also through the Peak District and into northern england, but clearing up towards the southwest later. Now, monday, ithink the gaps between the showers will be bigger, but therell still be plenty of showers around, so youll need your brolly at some point or another, good morning, welcome to breakfast with Nina Warhurst and rogerjohnson. 0ur headlines today.
