Those of us who wear glasses know exactly how annoying they 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? they are relatively cool compared to your breath, especially when outside areas cold. So in order to see things properly, we need to see things properly, we need to go outside. We are heading to go outside. We are heading to the stunning alps to meet the team from eta zurich to get hands—on with the glasses. , eth. This solar—powered innovation aims to end fog up lenses and we are here to see it in action. Traditionally surfaces coasted, coated with water attracting molecules which attracts an even spread of condensation. This is how regular antifog systems work. This new method heats the surface, preventing condensation from humidity forming in the first place. Eg�*s forming in the first place. 5096 ofthe forming in the first place. 5096 of the sunlight _ forming in the first place. 5096 of the sunlight is _ forming in the first place. “i:% of the sunlight is invisible and we're not seeing it with our human eye. It is infrared, and we designed a coding that absorbs this infrared energy, heats up the service and then can stop fog. The whole mission behind our coding is to make something that is durable and in comparison with existing antifog solutions which you always have to reapply, you use plastic bottles and we provide a durable one—stop solution that lasts. 50 a durable onestop solution that laste— that lasts. So this coating absorbs radiation, that lasts. So this coating absorbs radiation, but i that lasts. So this coating l absorbs radiation, but how that lasts. So this coating i absorbs radiation, but how do you ensure it is absorbing enough radiation and not too much heat with so it is practical? it much heat with so it is practical?— much heat with so it is practical? it is a subtle balance _ practical? it is a subtle balance. Obviously i practical? it is a subtle balance. Obviously the i practical? it is a subtle balance. Obviously the energy is limited to a certain extent, you cannot heat up to 100 celsius but we can tune actually how much infrared coating absorbs and also change the effect on the temperature. The coating is extremely in. It is perfectly clear but behind the scenes it is busy warming up the scenes it is busy warming up to block fog. No fog, no fuss. But how does it work, you ask? well, it is in layers. Each of this coating is a logo. The party in the middle contains gold and has the importantjob of soaking up all that radiation. One amounted 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 another sector because on the one hand you have the windshields that fog up and it always takes on while before they default but you'll have sensory radar systems in medical devices when you have human breath that can deteriorate a signal. This sunlight _ deteriorate a signal. This sunlight powered deteriorate a signal. This sunlight powered coating could change the way we see things, quite literally. So could this be the solution we have been waiting for? the future could look a whole lot clearer, powered by a little bit of sunshine and a dash of gold. .

It was released in 1994 and unbelievably it is still around today. A dead smart and elephant, its tasks removed. Poachers are suspected. To protect elements, the transnational trade in modern ivory is bound by international commercial, got they have that prohibited because they came from extinct ice age relatives. The woolly mammoth. Tons of ancient tasks are extracted from the frozen ground every year. Telling the difference between illegal elephant ivory was a real problem for border security and is even a challenge for mammoth experts at the natural history museum in london. Adrian, lovely to see you. In his office, the professor gathered together lots of examples of mammoth ivory. They are closely related to living elephants but they are adapted to the cold conditions of the ice age, and they had a huge distribution. It's been estimated there were probably as many as 10 million mammoths at their peak. How hard is it to tell a difference between mammoth ivory and elephant ivory? once a piece has been carved like this little mammoth model which is made of mammoth ivory however, if i didn't know that, i couldn't tell. Secondly, it's expensive and would take time — weeks — before you got the result. And if you're 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 can't do it. You couldn't, really. There's not really any way of knowing. I mean, we've 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 that's been in the museum for years. Here's an equivalent tusk tip from a mammoth, and all you would have to do would be to stain this a brown colour and you couldn't tell the difference. So this is a school of anatomy. You'd never guess, would you? laughter take care 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. There's 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 we're 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. I've 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. You're 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 it's a bit of a problem people trying to smuggle eggs of endangered bird species across the border from mexico. So the next project i'd like to get started is to see if we can tell the difference between eggs of different species. Since she published her results, dr shepherd's work has attracted international interest. So, i'm currently in hong kong, and i'm here to present my research at a workshop that's designed to get together people involved in preventing wildlife crime from across all of asia. So there's 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 don't 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 queen's wardrobe, the most elaborate parts of which — her crown and neckwear — were sd printed. More complex geometries, more innovative designs, and also in a more sustainable way. Julia koerner is an austrian designer and architect who specialises in sd printing high fashion pieces and products, couture dresses, bags, accessories and ornaments. But it was queen ramonda's fabulous attire that caught our eye and also those of the oscars judges. 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 sd 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 didn't 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 that's 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 you're 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 sd printing process. A prime example of this isjulia's setaejacket, which was shown in philadelphia's 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 first jacket made in this technique that a printer, like in an ink—jet printing process, puts the material layer by layer onto the jacket. Because it's printed in little dots and points, there's a certain flexibility which stays within the fabric. Sd 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 sd printing was going to take over the i world. . . . .
