When he claimed victory. I think all of you know we won the popular vote in iowa cheering and applause we won the New Hampshire primary cheering and applause and according to three networks and the ap, we have now won the nevada caucus. Cheering and applause his triumph cements his status as the Democrats National frontrunner, but it will deepen concern among moderates in a party who feel the self described democratic socialist is too liberal to defeat donald trump. Can we raise a couple of million bucks . Lets go get it former Vice President , joe biden, claimed what his team described as a strong second place, and success substantial enough to trigger a comeback, after a poor start to this primary season. So, it was a great night for bernie sanders, but there is no stopping to savour the taste of victory. Most candidates have already left nevada to campaign in super tuesday states, which will vote injust over a weeks time. The next debate is in three days. The gloves came off here in las vegas. The fight will continue in south carolina. Sophie long, bbc news, las vegas. Now its time for a look at the weather with nick miller. It looks like some of us will be dealing with snow for the monday morning commute, particularly on some of the higher routes across northern britain. Through this evening and into tonight, we bring in our next area of cloud and rain, pushing into colder air into scotland, Northern Ireland and Northern England, may be some slushy accumulations in places and several centimetres of snow into the higher hills here. All of that as we go through monday the further north into scotland. Even where it is clear, as the strong gusty wind picked up that snow may start to drift in places. Still snowy in parts of scotland for the afternoon and elsewhere in the west of england and elsewhere in the west of england and south of england, the rain will sweep south and leave brightest guys and a few showers. A windy day with gusty winds. Cold is where we have the snow, but it will finally clear on monday night, and we are in for a chilly two days with sunny spells and showers. This is bbc world news, the headlines now it is time to join the team for click. This week, making water out of thin air. Cyber security in saudi arabia. And fake frocks of the future. The code breaking of bletchley park, the gadgets used to conceal cold war secrets and how we can protect ourselves now online. This exhibition at Londons Science Museum marks a century of gchq making our nation a safer place. Protecting sensitive communication from hacking is nothing new, no matter what the technology of the age is. Here we have the telephone used by Winston Churchill in world war ii. Its called the secraphone and comes with a complete large privacy unit. Inside it, electronic circuits are scrambling both incoming and outgoing calls and then some years on, Margaret Thatcher used this secure briefcase telephone every day. The passcodes on it were changed to protect the encrypted calls. Hacking and cybercrime are of course regularly hitting the headlines now. Countries and companies around the globe are desperately trying to find ways to avoid falling victim. This month, the saudi Cyber Division hosted its first ever Cyber Security forum and click was provided with a rare invitation to saudi arabia to take a look at what the country has been working on, but with accusations that the regime has been carrying out campaigns of hacking against critics and journalists, we want to know, can the saudis be trusted in cyberspace . Joe tidy, the bbcs Cyber Security reporter, has been finding out. Its a country famous for its endless golden sands and vast riches built on one natural resource, oil. But as the world begins to wean itself of this valuable fossil fuel, its forcing a monumental shift in the sands. Saudi arabia is a country on the move. Things are changing here so rapidly in the way people live and work. The country is trying to diversify its away from just oil and this is a big part of it. This is digital city. A couple of years ago, these buildings werent here. This is part of the countrys drive to move into technologies and particularly Cyber Security. There are big ambitions here to create household names in Information Security and across riyadh, another sign of intent. This place is amazing. Its like Buckingham Palace with palm trees. For the first time ever, the government is hosting a global Cyber Security forum by throwing open the doors to foreign visitors, saudi arabia is inviting investment, collaboration and scrutiny. Whats funny about this conference, this Cyber Security conference, its not a conference, its a forum. There are no stands. We dont know who is here, which companies, but thats not to say there arent companies here. There are companies from all over the world. People are chatting, introductions are being made. Its predicted the saudi Cyber Security market could grow to 5. 5 billion by 2023. But there is another motivation. A devastating attack that the country is still reeling from. 2012s shamoon attack was a massive moment. It was the moment when tens of thousands of pcs at the countrys biggest company, saudi aramco, the worldss biggest oil producer, they went dark. They were hit by what we call a wiper virus, which, as the name implies, it deletes all the files on all the computers where its infected. Imagine if you will, its a bit like someone breaking into your house, and not only do they steal everything but they burn your house on the way out. The hack, which has been blamed on iran, took out 30,000 pcs. This spread got into the company by someone receiving an email and they double clicked on the attachment. From a cyber perspective, it really turned the dynamic on its head. We were thinking about the stereotypical, you think about some genius in a basement somewhere using all these commands whereas actually now what we see is very, very simple, its an email that comes through, there is a link in there and as long as you can trick the person into clicking the link or opening the file, you can have a very, very big impact. Since then, the country has been under almost constant attack. No wonder the country is on a mission to improve its Cyber Defence and encourage local talent to flourish. Saudi arabia was ranked 47 among 179 countries according to the itu, international telcommunications union, and the un. Throughout the last couple of years, the ranking has increased to be 13 globally. So we have seen saudi actually increasing the ranking, in a sense, because the ranking is directly linked to the level of commitment, the level of effort that country is putting into cyber. And here is one way the country is hoping to rise further the ranks. This is a hacker Training Exercise run by site, a government backed Cyber Security company. The teams are trying to capture a digital flag inside a secure server. So you are basically pretending to be hackers, you are. We are hackers. To break into the system. We try to break into the system and try to find where is the catches. Capture the flag will make you challenge yourself, how could you pass the wap, the firewall, the log in credentials and a lot of Cyber Security controls. Staying ahead of hackers is very tough, because technology advancement, the pace of technology advancement, is way fast, is way higher than the advancement we see in cyberspace. Amongst all the positivity here, and there is a lot of positivity, there is also an unspoken truth. Many of the people ive been speaking to, the international guests, have decided not to bring their devices, laptops and phones. This one isnt my usual phone and the reason for that is that there is concern about potential surveillance. Last month, amazon bossjeff bezos accused saudi arabias crown prince of hacking his phone. He received the file via whatsapp, it was a video file and upon clicking that, opening that, that infected his phone with a backdoor and that allowed someone to siphon off all his data. The kingdom says the allegation is absurd, however according to the united nations, there is also strong indications that saudi arabia hacked the telephone of dissidentjournalist Jamal Khashoggi before he was killed in the Saudi Embassy in turkey in 2018. It all raises questions which i put to the countrys Cyber Division. How do you think saudi arabia will respond to issues of cyber surveillance . As i mentioned earlier, our main focus is thinking how we ensure that we defend and protect our Critical National infrastructure, putting the right measurement, whether it is standardisation, building our capabilities and also enhancing those Cyber Protection efforts. Saudi is clearly trying to move on from uncomfortable allegations. The conference is a major part of this and the centrepiece of the event shows an emphasis again on defence, a game that puts players in the hot seat of an attack. So youre an it specialist and you are representing a petrochemical plant. So were going to go through the whole phase of an attack. So weve obviously got employees and they downloaded bad files, with malware. We need to stop more employees from downloading them. Correct. And weve run out of time, oh, no saudi arabia is at a crossroads, its opening up to the world and its clear it wants to be a big player on the global Cyber Security stage. It would be naive to think that other nations dont hack the security or economic reasons but an emerging force like saudi has to decide whether it wants to be seen as a team player or kept at arms length. Were almost there. Hey. We won, you take that. Well done. Here we go. There we go hello, and welcome to the week in tech. It was the week huawei lost its challenge in a us court to overturn the ban that prevented Government Agencies from working with the company. Apple warned disruption in china from the coronavirus would affect production and supply of iphones. And the worlds richest person, jeff bezos, pledged 10 billion of his 130 billion fortune to help address climate change. In new jetpack news, it seems we are ever closer to a real life iron man. A team atjetman dubai reached a major milestone with a jet powered wing suit which took off from a standing start and then flew up to nearly 6,000 feet in altitude and reached an average speed of 150mph and yes, they landed. Iron underwear optional. From rockets to bangers. Have you ever had problems grilling the perfect hot dog . There is a robot for that. Jako and baxter great names are Machine Learning robots developed by Boston University that are able to complete the more complex task of cooking and serving up a good sausage. And finally, would you trust a bee with a drone . Researchers at Sheffield University are reverse engineering bee brains to help create more advanced drone software. Tiny electrodes inserted into the bees brains will analyse their flight parts to work out how they can reliably navigate a 3d environment over several kilometres. Un bee lievable . Sorry. For over 30 years, London Fashion week has brought the latest trends and streetwear and couture to the capital. Whether spring or fall collections, it follows the same format. Catwalk shows from designers popping up all over the city. But in the near future, the catwalk could look completely different. The idea of gathering together to look at seasonal trends could be obsolete. Like many other industries, Artificial Intelligence is shaping the future of fashion. The designs, models and even the location of fashion week could one day be created by a computer programme. It is possible to generate these kind of captions with al algorithm. A new course at the London College of fashion is looking in detail at these issues, giving future designers and merchandisers the tools to work on this new world, influencing everything from pattern cutting to design. So if you know this type of algorithm, you canjust mine all over your database. These images were dreamt up by an algorithm that looked at tens of thousands of photos. So this is a computer that is designing these dresses . Yes, so this is a Generative Adversarial Network that has been fed many thousands of images so it begins to learn what a dress looks like. Its incredible. And then design its own. So every one of these is Computer Generated. Slightly terrifying. And similarly, this is taking thousands of catwalk images from mens fashion week and beginning to understand what a catwalk looks like, what a model looks like, what the clothes they are wearing looks like and generating its own catwalk images. Are these real models . These are Computer Generated. Oh, wow. So this person doesnt exist . No. It begins to question what we think a catwalk show could be. Could we get to the point in the future where are Computer Generated catwalk becomes as popular or as interesting as a physical catwalk . What do you think . Its not beyond the realms of impossibility. Indeed, the ideas and projects the students are working on would once have seemed impossible but they are certain the whole industry will soon change and having a background in ai will be essential to their success. In all the industries right now, its important to be able to cross collaborate, to be interdisciplinary and i think this is really important to have a knowledge of everything that is coming up and how we can use that in fashion. So with al, we will have much more ways and options. Like, instead of, i dont know, sketching 10 ideas, we could have thousands of them, you can just select quickly what we find beneficial for our project. But others worry about losing originality in this process. I think the danger is stripping out creativity because in many ways, that argument that designers create something from their brain, its not been done before but a looks at everything thats been done before and create something new so i think theres this, like, paradox. Does it mean that we will end up repeating the same things over and over or does it mean we will be given new ways to create . In fact, the a may end up being more creative than humans because it can process so many more images than we are capable of seeing. The course is also preparing students for job losses in their industry to Artificial Intelligence, especially in areas like pattern cutting and other repetitive work. This really is something we cant deny. It is coming and we need to be prepared for it. Maybe these people can be educated in some sort of position where they will be using this a to do this job but if it is something repetitive, if it can be automatised, it will be automised. The next experiment will be feeding this algorithm photos from architecture as well as the clothing to see what fashion designs it comes up with. An exciting time for those able to adapt, but with implications for workers around the world, perhaps a need to think quickly about the direction of this important industry. That wasjen. Now, over 2 billion people on the planet dont have access to clean Drinking Water. For over half of them, it would take at least 30 minutes to reach any. So nick kwek has been finding out how that safe water could be created out of thin air, literally. Access to clean water is a human right, yet over 500 Million People die each year from drinking contaminated water. According to the world health organization, in only five years time, half of us will live in a water stressed area. Thirsty for answers . Ive come to South Yorkshire to see a start up with a novel solution. Hogen systems is harvesting waterfrom thin air. Water is extracted from the bottom of the evaporator, collected in the tray and pumped out for use for drinking. Thats water in the tray there . Thats water in the tray there, yes. Thats come from thin air . Thats come from thin air. Ok, its a giant dehumidifier, but the game changer here is the artificially intelligent devices adaptability. Sensors all over the process that will detect what is the real temperature, what is the real pressure, the real humidity, the control system will further refine its control to make that the best way to operate. Keeping costs down is crucial, so using the least amount of energy possible is key. So the way this works is air comes down through here, gets sucked in through the evaporator, which pulls moisture out of the air. The water then drips down into this water tray and the byproduct, which is cold air, gets sucked through there, which could be used for air conditioning in the summer, and another byproduct is heat generated through the condenser, which could be used to heat homes in the winter or wherever it may be used. Shall we give it a taste . Well, why not . There we are, water from thin air. Yes. It does have essence of machine about it. It may do. It does have a somewhat metallic. I mean, if i were to lick that machine, a kind of feel like thats what that tastes like. Yum, yum. But im assured after a few gallons circulate the machine, it tastes much better and makes a banging brew. As well as large scale units, hogen has also developed a more mobile version targeted for the military. The more compact version has actually got two systems built in for redundancy, so if one goes, there is a back up option. We know of some customers in the middle east who are shipping Drinking Water by helicopter. The cost of shipping Drinking Water by h
