And when youre fertile. And open wide. Alasdair, well take you through now. Alasdair� s taken a trip to the dentist to look at a device that may help prevent. Well, further trips to the dentist. I think theres a misconception that once decay starts, it has to end up in a cavity. But if we can identify. At that early white spot, then we can start to get the tooth to reform. In the centre of london, there is a building like no other an empty space where the public can sit, relax and look up. I have to say, of all the giant led screens ive seen in my time, this ones right up there. I mean, its literally right up there. Well, yes, and it seems like it goes on and on and on. Yeah. And it also makes you feel rather dizzy looking at it. They laugh this is outernet, the largest digital exhibition space in europe. Here, an array of artists work is displayed in its full panoramic glory. Aside from the huge cube that spun laura out. You were 0k in the end, werent you . I was. Good. There are a few other spaces dotted around, too, which are used to showcase specific exhibits. This room celebrates the role that women from all backgrounds have played in shaping the creative industries. And its just one example of Immersive Technology bringing us closer to the events of today and the past. But some events are hard to face, even though its important to do so. And one of the most important is the holocaust. Its now been many decades since its horrors took place, and as time goes on, fewer survivors are around to be able to tell their stories. For a while now, researchers have been documenting them digitally so their legacy can live on for future generations. And, of course, there are now new ways to breathe new life into those memories. And nick kwek has been to meta in berlin to find out more. Nick a stones throw from the memorial to the murdered jews of europe, ive come to metas offices to try its latest extended reality project. Im the first journalist from outside germany to see the new interactive Holocaust Education tool. Tell me, inge takes users on an audiovisual journey into the memories of inge auerbacher, a survivor of the nazi regime. You ask inge questions by simply talking, and the artificially intelligent system will play out her response. Tell me about the terrible journey. Inge one morningl when i was seven. Its a real recorded answer, not a digitally doctored version. 0h, inges showing me something. Shes opened up a box. But its presented to you like youre inside a video game, a moving storybook, with your environment changing around you, as inge recounts more anecdotes and details from her past. Thats pretty cool. So shes opened a book and then we can see, floating up over her right hand shoulder, the book. Its a joint project with hollywood start up storyfile, which is now moving beyond Computer Screens and is stepping into uncharted virtual territory. Its a little bit tense in this space, i have to say. It feels. A bit eerie. I feel quite nervous about it all. My hands are sweating a bit, but it also is great to kind of see her stories come to life in this way. It makes you focus more on what shes saying. In a strange way, youre almost being entertained. The experience was made in partnership with unesco, Claims Conference and world jewish congress. You can take the story wherever you want to take the story. You can ask for it in whatever order you want to ask. I mean, you cant really ask for something more engaging at this point than that. You know, we used to sit in. You know, in Memorial Museums and kind of read the texts and be told some of the stories behind them. But this is a completely different level. There are two nazi guards. At the gate. Almost touch it. So far away there was absolutely almost no chance to get out. Its really sad. Well. Is there a fine line, though, when it comes to designing an experience, where you want to make it engaging but maybe not too immersive . You shouldnt overwhelm someone emotionally. And i think, especially because of this, we decided to use Sd Animations that make things real, but its not realistic. And so you get a sense of what was going on. And, of course, you hear from inge first hand, but still, you know, theres some sort of a distance because its not like that you see real soldiers, not like you see real people getting hurt, and so on and so on. But you understand how the scenery was looking like. Ive been working on genocide and holocaust commemoration issues for many years. These topics are not easy. The immersive part of it really makes you also feel like youre part of the life of the people. And seeing inge, where she is today, and seeing that there is a life for survivors and how she made a life for herself and how strong she is, is also part of, you know, the positive part of experiencing this. Thanks so much forjoining us. Its a real pleasure to meet you. Have you got to try the experience yourself . Have you seen what you look like. Yeah. In Virtual Reality . Yeah, ilook. Yes, i look pretty good. I was satisfied. She laughs when you read a book, | sometimes you would like to speak| to that person in the book, to converse with that person. But you cant. You have to continue reading. And i think, this way, this new method gives you this insight. Unfortunately, you cant ask inge any old question. It has to be in some way connected to answers that she originally recorded. But whats really clever here is how the application expands once you get to know inge more. Her grandads just popped up there. As your Curiosity Piques i and you come back to inge after the first story has been told, you find theres a sequel to that, i some follow up that you can then ask iabout, which then takes you on thisl journey and these branches through her life. And thats how we structured this, not as a linear storytelling were not watching a movie. We are actually delving. Into her life and allowing, just as we would do in conversation, different aspects of that life to unfold as we talk to her. Right now, you can only hear from inge in english and german, but down the line, stephen says, using ai, she could be translated into various languages so everyone can access it. What was the experience like, being in the studio, being asked all these questions . I dont know. Im a talker. I dont mind answering anything because when im gone, im gone. Its finished. History is gone. This is more than bringing back a dead person, you know, because thats not possible. But this way you can make that person. Give them a thousand years of life. I think thats wonderful. Lara over the years, weve covered the highs and the lows. Spencer a lot of lows. Of cryptocurrencies. Yeah, there are plenty of people who still hope that these unregulated Digital Currencies will replace traditional payments for goods and services. But the reality is you still cant buy much with crypto, which leaves it mainly as a high risk investment. Yes, Crypto Assets are notoriously volatile in value. Get this according to one report, hackers have already got their hands on 200 million this year alone. So if you do hold Crypto Assets, what can you do to reduce those risks . Cyber correspondent joe tidy has been taking a look at crypto wallets. Joe its estimated there could be as many as 400 Million People around the world who hold cryptocurrency. But its thought a tiny fraction, around 8 million, are securing their coins offline to protect from crypto hackers or companies collapsing. Remember ftx . Its been nearly a year since that imploded, and still a Million People are missing their coins. The safest way to protect your crypto is with a Hardware Wallet, which is, oddly, a physical device. So lets see for ourselves, then. Just how hard is it to take bitcoin from an exchange and put it onto a Hardware Wallet, like this . The idea of a Hardware Wallet is very simple. It holds the private keys to your digital wallet, making you your own bank, just as cryptos inventors envisaged. With the key stored safely off the internet on a physical device, your coins are safe. Ive got hold of one of the most popular ones to test it out. So, ive got to go to the trezor website, and ive got to download their software. Youve got to make sure, of course, that you put in the right web address, because this will be a prime time. I imagine that hackers and scammers will want to get you to go on their fake trezor website or fake ledger website and hand over your bitcoin by mistake. Then, you have to plug in cables and install some firmware. So far, so good. Ok, so now its telling me that i need to create a backup for my crypto wallet, and its giving me some randomly generated words which are my seed phrase, and, weirdly, its asking me to write them down. This so called seed phrase allows me a way back to my currency if i lose or break the hardware. So this feels like a really analogue way of securing my crypto. Ive got this Hardware Wallet, which ive obviously. You know, they cost money, a lot of money, but then theyve just given me a pen and paper. Now is the potentially tricky bit. I need to somehow get my coins from the exchange. In this case, binance, one of the most popular in the world. Onto this wallet. I had a feeling this would be where it gets tricky. How do you get your money off the exchange . Ok, so ive got a qr code now for my new wallet, so im going to scan that with the app. Invalid. Right. Ok, so, what do i do now . After a bit of good, Old Fashioned online troubleshooting, were in. Its a bit worrying, this moment, because, of course, ive had this cryptocurrency for years and years. Theres not much there, butjust sort of trusting the process. So, here we go. Im going to click on withdraw. Just have to wait. I hope it worked. Now, that was stressful and complicated, but im now my own crypto bank. No one has access to my little stash apart from me, but its also a lot of pressure. Its just such a different experience from internet banking, for example, where, you know, you send money from one person to the next, then it keeps you informed of. You know, of all the process, but its not intuitive at all. I can see why the process is daunting to the vast majority out there, choosing to take the easier route and just hope that their coins stay safe online. As is always the case with crypto, its a gamble. The bbc approach the company for comment but has not received a response. The Us National Accelerator lab has created the worlds most powerful laser.

Spencer now, theres been a recent explosion of misinformation on social media, encouraging women to ditch Hormonal Contraception, due to fears about side effects. And influencers are promoting the use of apps to prevent pregnancy instead. Lara investigative journalist Katie Mcevinney has been meeting women whove used these apps, with a very mixed bag of results. Lets take control of our fertility. Katie so called natural alternatives to Hormonal Contraception are everywhere on social media, from the Fertility Awareness Method to period tracking apps. This is my birth control. 0ne popular app is called Natural Cycles. With 2. 5 million registered users, it sells itself as digital contraception. The Company Behind it says its 93 effective with typical use. The same, they say, as the pill. Camera clicks. And influencers advertise it a lot. This is my app. 0k. Foramelia, its worked for five years. She tracks her fertility by measuring her temperature. You press the button. Thermometer beeps. So you just put it under your tongue, and you wait for it to beep. Thermometer beeps. Like that. And itll tell you what your temperature is. So you put in your temperature for the day. If youre sick, it could change your temperature, obviously, like, if you didnt sleep very well, or if youre hung over. Then, it kind of like discounts your temperature for that day. Thats something that i would really worry about. Yeah. Like, if you have a long lie or youre hung over, it would affect how accurate it is. Yeah, which it definitely does. So it, like, rules out that whole temperature for that day. It tells you when youre not fertile and when youre fertile. So, when it says not fertile, its safe to have unprotected sex. But if it changes to red, that means you need to be more careful and use a condom if youre having sex. Its made a big difference, in that im not relying on a hormonal pill every day that could mess with my mood. It does take a lot of work on your part to get used to taking your temperature and putting it in the app. It works for amelia, but does it work for everyone . Say hi. Meet penelope, matildas much loved but very unexpected baby girl. Boo. Matilda tried the pill, the injection and the coil, but none of them suited her. I went back to the doctors, and within, like, a couple of weeks, i felt back to myself again, but was, of course, like, suffering with my periods still. I didnt want to go on any Hormonal Contraception. I dont feel like anythings suited me. Ive been doing this for, like, eight years at this point, from, like, 12 to 20, where im either bleeding all the time or not bleeding or suffering and in pain, and theyjust kind of turned around and said that there wasnt really anything that you could do to help with that. At this point, im, like, 22, in a relationship, but by no means at a point where im ready to, like, try for a baby or have a family. She says she found Natural Cycles advertised on social media, and followed the Apps Instructions immediately. Ijust saw it. I think, green and red, most people think, if youre sat at a traffic light, red means stop, green means go. I assumed the fact that id entered my data meant that they knew enough about my body and my cycle that i could be having unprotected sex. I had been using it from the december, and by the january, id found out that i was pregnant. Itjust wasnt something i think i was quite ready for at the age i was, maybe. 0bviously, ive come to terms with it, and i love it now, but it was definitely a massive shock. Natural cycles says the app is effective from day one, and that it will only give you green days when it has enough data to do so. I think effective from day one is, like, a very bold statement to make. I think the app putting something forward that, after six months, you can be having a happy and hormone free life, that would be a better statement to make than saying its effective from day one. But that was definitely what attracted me to the app in the first place. Its been such a challenge, but obviously one of the best things ever. Shes been brilliant. For someone who, maybe, getting pregnant today wasnt quite the plan, but if it happened, it. |would still be a happy surprise, | then methods that are a bit less effective, like the period apps, can be great for them. But for somebody who really doesnt want to be pregnant. Actually ditching, potentially, a very effective method of contraception for an app that requires a lot of user input and might be less effective. Is really worrying. Natural cycles told us that no method of contraception is 100 effective, even when used perfectly. In a statement, it said, Less Thani In 100 Women become pregnant due to the algorithm assigning a green day when a user is fertile. And the methods real life effectiveness is the same as its published rates. 0k, were going to stay with health now. What is one thing that we should all do quite regularly but which most people dont enjoy doing . Go to the dentist. Yes. What is the thing the dentist tells me to do more of every time i go . Flossing . And what do i then not do for the next six months . Flossing . Correct. And for anybody who doesnt do their flossing properly, like him, well, a new device that Alasdair Keane has been to find out about could come to the rescue. It aims to identify decay before it causes a problem. Have you got something stuck in your teeth there . Mm hm. Alasdair weve all been here the long wait to see the dentist. Alasdair, well take you through now. Not always peoples favourite place to be. Thankfully, im not here for treatment, but to see the latest tech that could revolutionise detection of decay and allow changes to be made before it gets so bad you need a filling. So this is the new Calcivis Technology that were talking about. Basically, its a Specialised Intraoral Camera thats capable of actually visualising tooth decay, really, as its happening, live. So it uses bioluminescence to be able to see calcium ions coming off a tooth surface, which is a marker of active disease. The inspiration for that process started somewhere unusual deep in the sea, and bioluminescence in fish. Its a completely new form of dental imaging. If you think about radiographs, for example, x ray, thats about giving you a snapshot of damage thats already happened to a tooths surface. Now, what our technology does is it allows you to see whether that decay is happening on the day that youre looking at that tooth surface. So its giving you information about whats going to happen in the future, Rather Thanjust whats happened in the past. Because of that, this device can identify the decay at such an early stage its possible to reverse it with cleaning, meaning you wont have to go under the drill. So, in here, we have a syringe that holds the photoprotein, which is the active component that gives off light when it comes into contact with calcium on the tooth. And as its being applied to the tooth, theres a camera. Yes. So, at the end here, theres a camera. It can give you a live video feed while youre positioning and then capture the still images when the photoprotein� s applied. Youve got some fake teeth somewhere that we can have a go with. So, at the moment, youre getting a live Video Feed Showing on the computer, and thats used just for positioning, to make sure youre getting the tooth centred in the image. When you press the button. Device clicks. Youll hear a click. Thats the Photoprotein Being applied to the tooth, and you get an image of the light coming from the photoprotein, showing where there is tooth decay. So look at this one here. This is low level caries. So the light blue in here is showing where theres calcium ions coming from this fissure pattern. And this is the kind of level that were really aiming at detecting. So this is where you could do something about it. You could reverse this process and prevent this becoming a cavity. Back in the dental surgery, and dentists like leanne can see the impact this device could have on dental care. I think theres a misconception that, once decay starts, it has to end up in a cavity, and its not always a big gaping hole. It starts with a small white lesion on the tooth, and then it will progress to brown, and then eventually, because it forms from the inside out, it will start to cavitate in. And thats, most of the time, when the patient becomes aware. But if we can identify at that early white spot, then we can start to get the tooth to reform and to rebuild. But leanne and dentists in other parts of the world will have to wait a little longer for this tech. The company are going to launch in america first, early next year. Wed really like to see it. Become standard of care. The move from the drill fill. Paradigm, through to a more preventive approach to dentistry is. I mean, its ongoing, and we think our technology is part of enabling that move towards a more preventive dentistry. Lots of people are nervous about going to the dentist. What would you say to someone that maybe is quite nervous about this tech . I think its about the overall environment, the overall treatment environment and the way that the practice sets themselves up. Because if the patient knows everything that the dentist l is trying to do for them is about avoiding cutting into a tooth. You know, its almost a sort of before and after. So here is a problem. That you have currently. Were going to do the following. Three months time, i six months time, were going to follow up and were going to show you that weve essentially turned off that activity. With that reassurance, i couldnt resist the chance to get my own teeth checked out. They were fine, but i probably should remember to floss more. That was alasdair, and thats it from 0uternet. Yeah. Thanks for watching, and we will see you soon. Bye. Hello. For most parts of the uk, a chilly start has given way to some saturday sunshine. But there are some changes to come through the rest of the weekend. It is going to turn a little bit warmer, but its also going to turn wetter and windier thanks to this Weather System, which you can see on our earlier satellite picture. This contains the remnants of what was hurricane nigel, certainly not a hurricane any more, but an injection of tropical moisture thats going to bring some heavy rain and some slightly higher temperatures for the rest of the day. Well see cloud and some rain spreading into Western Parts of the uk, particularly Northern Ireland. Still on the cool side for the time being. And then as we head through this evening and tonight, well see strong winds and some outbreaks of rain across Western Parts. Another pulse of rain starting to push up towards the South West Of England and wales by the end of the night. So it is going to be milder than last night. In fact, by the start of sunday morning, 11 to 16 degrees. But for sunday, we see this Wriggling Frontal System which will continue to bring some outbreaks of heavy rain, especially across western areas. And we will have some pretty strong winds. So these outbreaks of rain through sunday spreading across Western Parts of england and wales, a bit of rain for Northern Ireland, some rain returning to the south west of scotland, all the while east anglia and the south east staying mostly dry with a little bit of sunshine. Temperatures here up to 20 or 21 degrees. A warmer day generally, in spite of the cloud, in spite of the outbreaks of rain, because the winds will be coming up from the south. Now into sunday evening, well see some very heavy bursts of rain pushing in across western areas, some squally downpours with some gusty winds. In fact, we could see wind gusts of 50 to 60 Miles Per Hour and some particularly wet weather moving across some western and central parts of scotland. The Weather System responsible will tend to clear through as we head into monday, but low pressure still in charge of the scene. As we head into monday, we will see some pretty heavy showers, maybe some thundery ones across parts of Northern Ireland and western scotland, further south and east across england and wales, more in the way of dry weather, some spells of sunshine, and it is going to feel quite warm out there with highs of 22 in the south east corner. As we look further ahead, it is going to be a very unsettled week. There will be some outbreaks of heavy rain and potentially some very strong winds for some of us around the middle of the week. Live from london. This is bbc news. A Missile Strike on russias Black Sea Fleet in occupied crimea ukraines Military Intelligence chief claims russian commanders are among those injured. In the uk, borisjohnson urges the government not to scale back plans to build the hs2 high speed rail link amid Speculation Part of the route could be axed. And the Liberal Democrats on earth, they say they have fired the starting gun on the general election. Separatists in Nagono Karabakh give up their weapons, as humanitarian aid begins to reach the thousands stuck in the enclave. Hello, im rich preston. Ukraine says russian commanders were among those injured in fridays Missile Strikes on the headquarters of russias Black Sea Fleet in occupied crimea. The building in sevastopol appears to have been hit by at least two missiles, causing extensive damage. There are reports that the missiles used were storm shadow missiles supplied by britain and france. It comes as reports in us media suggest america is planning to give ukraine more advanced, longer range missiles to help with its ongoing counteroffensive against russia. With me is the bbc� s europe regional editor, danny aeberhard. Who can tell us more. What has each side been saying about this attack . Weve had a new interview the head of the
