rice, you are up to date. uh, don't forget, just country, more news and information on our website. you don't. com and you can follow us on our social media accounts or handle is d. w use for me as a team here in berlin, x watching. take care the much as to what did you do before i came to china. she survived our scripts. thanks to music. he was the nazis favorite conductor. he is martin, the, the genuine, 2 musicians under the swastika, a documentary about this sounds of power, inspiring story about survival of the home and you go get the tennis. i was the

only one who lives in nazi germany. watch now on youtube dw documentary. what do you want to pay for your groceries or coffee with your face? that seems pretty convenient, but is it said kill lauren this in a moment also on the sho, families of victims of us school shooting, assuming a gaming company on the social media platform. and he waves all scorching the globe tech might help us tackle the problem. we'll show you the latest development these other topics that i'm moving the tech world. have you ever paid in the shop simply by showing your face chopped as odd that you will? how does it work? well, it's very simple. first, you capture your biometrics by activating your camera or even with a simple selfie. the face is then broken down into data points,

which is stored and so called tokens. so there is no photo of the stored on a server somewhat. the tokens are enough to identify your face, then you need to connect your face data to your bank account or credit card. if you are in a store or restaurant that supports pay by face, you simply press the button on the payments having on the device, scan in your face. and while you just paid with your face, meaning you've gone to the restaurant permission to debit the payments from your bank accounts. is it secure? biometric authentication is a lot safer technology than passwords or pins. a face scan is also also chosen other biometrics, like a fingerprint, according to manufacturer, has a face comp they have like a password. the systems also have extra security last and that will con, be easily tricked by a photo of person or even by mosque. the technology isn't into effect though. it's not recommended for children under the teams, because best facial features may not be fully developed. and how about people that look just like the sibling, say twins with a twin,

be able to use the own phase to make payments, and the siblings name without the knowledge? well, pay by face companies at least combo but out if you have a twin, i'm not concerned about them using your account. without your authorization. you should immediately set the custom pin after you create your pop id account. that's what phase payment service pop id sets. but what is the catch? as often your convenience comes with the exposure of your data. biometric tokens make it not charge for criminals to hacked your accounts. but security active as a warning, the biometrics theft is becoming more common placed. there is even more to consider some political regimes try to track and identify people using facial recognition systems in order to identify say, protested they need a data base to compare the data to. so they could be very interested and you'll pay by face data and even low tech companies assure us that our data is encrypted and still securely. we have seen companies hand out data to governments before. so

definitely make sure that you trust any company. you use this technology with 2 big names in tech, a being sued over the alleged role in the us school shooting one is activision, the company that makes the 1st person shooter games cool of duty for you is the player. use a weapon yourself and the game. this ego perspective is what gives the genre it's name ego sheer to the other. a is meant to parent company of instagram on facebook . families of victims are accusing the tech funds of collaborating with the fire arms industry. the claim, the best some responsibility for the shooting is what you need to know. in may 20, 2218 year old salvador ramos, a former student, a rock elementary school, say to they show 19 students and 2 teachers. 17 others were injured, but survived. ramos was shot on site by police officers. this tragic incident re ignited heated discussions about american gun culture and violence. now families of

the victims claim that gaming company, activision, and social media company, meta bass, some responsibility in a separate law suit. they also swing fire manufacturer, daniel defense, which made the rightful used and the shooting spin diamond reeves over the last 15 years, 2 of america's largest technology companies have collaborated with the fi um the district. that's a serious accusation. is meta promoting guns and do egos shooters to and getting those into tell us as well the scientific verdicts on the last lot to is rather clear. that is no causal link between playing video games and gun violence in real life. that's according to a majority of scientists and a recent review of 82 medical research articles on the topics drew the same conclusion. but the plaintiff, i'm not targeting this link between gaming and violence, they are targeting a special feature of color due to what the weapons in the game mimic real life weapons. basically,

they are claiming the games to just pay us how to handle firearms. then diamond states, but even though killing is parts of many games, the look and feel of the gums and cool of g t is extremely realistic backups people, especially young ones, interested in buying real lessons. the fix a weapon in the game called of j t called m for a one is strongly based on existing a off of the models. the sheer to solve with a ramos use such a weapon and you've all the, and a off of things have also been involved. and 10 of the us is 17 dead list. my shootings since 2012 and other titles of the cool daisy franchise activism actually had licensing deals with gun manufacturer as a use real gun names of the legal problems they decided to work with lookalikes for the plaintiff. that is simply not good enough. they've made some serious allegations, the defendants bear responsibility for this profound corruption of our children in concert with certain file manufacturer as they have groomed a generation of young man who

a socially vulnerable and secure about the masculinity and eager to show strength on a set dominance defendants have spent years positioning the counterparts and the gun industry as the answer to those problems. the summit up, the trial is not about the question of why the 1st person, shooter games incite violence, but about whether quality is promoting guns, teaching people how to handle them, selling guns by social media. the accusations against metal similar met the social media of instagram office by all manufacturer. something even cool of gc kind of the supervisor's child has been directly to mind those in the homes of school. even in the middle of the night, according to the law says you've all the shooter was talking to the instagram via daniel defense lessons manufacturer that produces a all 15 bicycles. daniel defense is also being sued by the plaintive, because officially guns sales also been an unmet. in reality, the company discloses little information about how it enforces that an

investigation by the washington post even revealed the guns buyers and sellers on facebook to violate the rules. 10 times before they got kicked all apart from that method, insufficient regulation of it's at it for system has been heavily criticized. but yet it's hard to predict how all of this will play out in court. but what do you think of these valid arguments? let us know your opinion. sweating buckets these days. you're not alone. he way of us scorching the globe this year. that's already been rec, what? breaking temperatures in india, mexico and more and regions like south america and south east asia have been hit with a wave tube. it's a huge button for people, a nature. when temperature has regularly exceed 40 degrees celsius, the number of people exposed to extreme heat is growing rapidly. maybe half a 1000000 lives a loss to it each year. the situation is grim, i'm gonna need solutions but climate crisis fast. but how can we deal with this heat up full tech solutions that might help?

first them a regulatory clothing, bit of a mouthful to say, versus scientists have developed the fabric keys in graphing, cruelty down in hot weather, and we'll see of when it's cold. so how does it work? well, a body is radiated heat in the form of electromagnetic waves. graphing can help regulate body temperature, either keeping the heat in or releasing it. whether it warms or cools can be changed by applying electricity to the fabric doesn't sound like the most practical solution when you're out and about and the weather changes. another group of research has proposed flaps that respond to a temperature, saying close when it's cold and bending to release excess heat when it's hot. the good thing about this solution, you don't need external electricity to tell the fabric that keep the heat in or release it. the 2nd solution, cooling, paint, american, re, such as developed a paint that reflects 98 percent of sunlight. cooling services, up to 10 degrees celsius below ambien temperature. meanwhile, and is really stop up is working on a multi lead coating the cools when hit by sunlight. the sunlight is absorbed by

the layers and re admitted with less energy. the remaining energy causes hate to admit from the lower light, which cools it down. it could be used to co rules, but also other things like cos. thirdly sunglasses for windows and china. research has created a transparent film that changes color block sunlight. unlike traditionally tempted windows. this film can switch back to being transparent as single light in when it's needed. and i'm finally hit map. they essentially show you why it's hot away, you might find a cooler place. this works by sensors around the city mapping. the heat. citizens could view such maps by a smartphone ops applying that route accordingly. additionally, he maps could provide further information like where to find the next pulling sentence. a cooling center is an ad conditioned quiet room where people can recover from heat stress for a few hours. in addition to the cool uh, that's a supply of drinking water. as a particularly high risk of dehydration,

when it's hot sounds pretty nice, but why come we'll just use conditioning? it's been, i'll go to solutions to combat thing hate. but as conditioning is simply not sustainable ac units or energy hawks, leading to higher electricity consumption and more greenhouse gas emissions, which accelerate global warming, that brings us to the real problem. bustling heat waves is only bustling the symptoms. as long as we're not doing everything we can to slow down climate change, they will only get worse. so how can we use a c sustainably? well 1st the energy use to power air conditioners needs to be sustainable. wind, so uh, what's the name? it's not grades could then optimize energy distribution reducing losses and allowing most devices to be pilot. this works by using a, i lots of data gathered from sensors around cities. let's say for example, the temperatures are rising and a so it's an area for small system within distribution will power to that sound

because it expects people to turn on that ac units. sounds good. but when we actually get that, well, even though these technologies have potential, widespread adoption is still a long way off. firstly, that price is not every city can afford to build a smart grid or houses with cooling, paint, or some kind of, but don't want to invest the money. secondly, old infrastructure needs to be updated, which takes time. result says a big workforce. and lastly, regulatory hurdles kind of lazy implementation of the tax. what's your take on this content knowledge you really helped tackle climate change, or is it just dropping the ocean that us? no, that's it from me. see you next time the are you a fan? are you a real fan for the years in germany this summer we want to know what makes german

football culture so special the you just have to see to go the, the 50 down. this is. yeah, i think it was and someone came in the opposite advise the how much to use for freedom is on and is tiny house concepts with conversations, cooking and music. oh, i'm val 30 minute d, w. we are all set and we're watching closely in the we can use the story behind the news. we're room about

unbiased information for 3 months. the is to city of strasbourg as good as it looks on photos. we visited one of the oldest european cities to find out on sesame street. everything's a ok, especially now that the german version has its 1st method with a disability. and what's the story behind this? typical sweet and very crunchy italian pastry. we get the secret of how biscotti the potto is made, coming up on your own macs. the 1st.
