new mil, dual life sciences are hoping that they can bring this bases back from the edge of extinction with the surrogate mother. you're watching dw news more news at the top of the our see you then the sometimes the show right? how that you out to the highlight for sure every week. nothing not. 7 yells engine, you belong to the 77 percent to come to i don't go and $65.00 full was last. you'll stop. and here's 3 reasons why. 1115. we're here to help you make up your mind. we are here on please find your mind. so all the topics i'm much up to you from trouble, it's all fixed. a new culture and then 15 minutes left side of the

community life on the service. the research is now on the. ringback on september 7th, 2010 seemingly small incident in the middle of the eastern us change the course of history. chinese preaching trauma and to japanese coast guard ships collided in the disputed waters. the japanese coast got the team to skip the tensions between the 2 countries have been rising. o. yeah. and the chinese government was it canceled high level political meetings with japanese officials, reportedly reduced exports of crucial re of elements to japan. china has denied this has happened, and it's paid by how much they reduce their exports. but what is clear is that the small events mock, the stock of an incredible price search in a world wide frenzy to secure these rare of elements. arguably,

the most important of them being this new to me is a weird little element that we'll talk lawsuit, you know, do, man is hidden all the way down here in the periodic system. it's one of the 17 read elements which are actually not that read all these metals were 1st considered rare because they have never been seen before. but really us like new to me and quite abundant in the us crust. it's just very hard to separate them from the material around them. what it was discovered in 1885 by this austrian scientist. nobody really knew what to do with it. from the 19 twenty's own word, it was used to color the last type of fancy. but still not very useful, but in 1983 researches from general motors and the japanese conglomerate. so me to more independently announced a huge invention at the same conference. if you combine new to me and together with

boy on an iron, you'd get really, really strong magnet today. now to me, i'm itself is also used in special protective last and for lasers among other things. but the magnet is what turned out to be a game changer. this is a regular affair, right? magna probably what's in your normal fridge magnet? i mean, they're super easy to separate. no problem. this is what's called a supervisor. and they are super strong. oh my god, the i swear to god, i'm not that week. now do me a magnus can be up to 10 times stronger than fair, right? magnets. normally, the 9th is ation of breaks up into the subdomains, punting in different directions. this is michael kelly, a professor who has been researching magnets for over 50 years. we don't want that to happen. to have a good use, usable, permanent,

magnus. we want them all to be in the same direction. and the way you do that is allowing the on with another element, which is new to me, which is the best one a for this purpose. that makes these now do me a magnet, crucial for things like electric cause wind turbines or even your phone. so a quick refresher why we need magnets for these things in the 1st place, store and making the simplest electric martha from these monuments, a battery and some copper wire. frustrated to put this battery at one of these magnets. so and then you need to form your copper in a type of full service. now, do me a magnet already creating a really strong magnetic field. this battery is low energy, so the top of this corpus board needs to touch the battery. and the button pop needs to touch the magnet so that the electricity can flow through

on it. and this happens because of the principal called the lawrenceville. you may remember from high school, this is how we convert electrical energy into mechanical energy. so this is a basic principle of how an electric motor to works. and that's what we use also for electric costs, the same principle, good for wind turbines. just the other way around this mechanical energy is then turned into electrical energy through the magnet inside here and the comp us pool. so in the bigger versions of these, instead of the l, a. d being less often that the electric energy that the generated, it's fed into the grid. so the strong of a magnet, the better, and these now do me a magnets of a strong this commercial magnets on the market. they also relatively cheap, and to the how to de magnetize the invention of now,

do me. a magnets pays the way for more efficient electric motors. they're more compact and light to because these magnets are so powerful that even call comparatively small ones get the job done. today many electric cars contain an average of about the kilogram of new. do me a magnets. wind turbines use much, much more deposit tongue turbine. these are also really important in order to equipment like these headphones, old big speakers inside these broken headphones. this still should be some magnets . so list to get. well, that was easy. in these headphones, you have a cup of spoil and a magnet. the electricity is converted into movement, which then is converted into audio waves. in the case of your phone, there's a tiny magnet in here. and that causes the starting to vibrate most of the medium well by there's going to be use for electric,

causing wind turbines without popping up everywhere. this is why the mountaineer do me. it is only projected to grow and could out strip supply. but let's rewind back to that boat incident for a minute. it wasn't just depends that kind of good little when they realized how dependent they had become on rent of mine, china, the price of me or do me, i'm showing up dramatically after the collision. it's all born out of this, this fear from the big, the concentration that you the race and it's been 20 times with china. this is michelle bustamante. she looks like critical minerals and their impact on land and natural resources. i have seen the concerns around these types of materials lead a lot of countries to become more resourceful, naturalist and i solution s and want to mine all of our own stuff and only,

you know, produce everything domestically australia way, right? so relatively abundant has scaled up its production significantly of the us reopened. it's one rate as mine in 27th yamaha has scaled up it's mining, but exports. a lot of it's rare us to china. india once to quadruple it's domestic production in the coming decade. but scaling up new to me and production is still far from easy. the problem is getting this element out of the new do, ma'am, is found jumbled together with other similar elements purifying. it takes a lot of steps that process use as many acids and solve instead of detrimental to the environment and hazardous to work as not only that, whenever unique challenges associated with rear or mining often is that they're mixed up a lot of the or is mixed stuff with highly radioactive elements. that's why even 10 years after the f crisis,

china is still the main producer of these elements. and they would do me along with other way of elements, has been hot topics during recent trade. tensions and prices are starting to. 1 again, the problem is that these new do me a magnet off so great that it's really hard to replace them. but people have tried to find other ones, other combinations of on with different rats. and some of them have been somewhat successful, but nothing as good as meeting them all these details about the mythology. much, much to what does work though, is using less of it more efficiently. for example, in electric motors, we found that the you could not surely replace 50 percent of your day ma'am, with fair, right? marketing without compromising in performance. this is a cannot live it in. he's a chemist, developing new methods to recycle and substitute new to me a magnet the so is it mother off all the time of these and

substitution, but not for the power replacement. recycling always seems like the most obvious solution, but when the very early stages stokes, in personal electronics, these magnets are small and hot to retrieve because they're built in with other materials, making it easier to just use new new to me. but since the wind turbine and electric call, markets are also expected to keep on growing. it could incentivize more recycling. and since the magnets use there are bigger it could be more cost effective. i can tell you that we are making version from this approach is to recover these forever elements in an environment. since we call the assets free, the solution office with this method there is no need to pre sold and separate out rid of magnets, one by one instead of toxic assets. the process use is called the sold and selectively lead to our rent. and these are examples of rare elements that we're recover from these it would make it even easier if manufacturer is already built.

they've products with recycling in mind when we create the currently sustainable supply chains that involve a high degree of reduce recycling. that's when we're really gonna solve the problem is that create all this fear not just by trying to mind everything ourselves as individual nation. so it's unlikely that this obscure element is going out of fashion anytime soon. did you know about super magnets in there? do me m, please let us know in the comments and subscribe. we post videos like this, every 5 the,

the, the, into the conflicts own with tim, sebastian. i guess this week is alexi, gunter and co. you creating an m. p. angelica parliamentary, assembly council of yours. hello, is this the best time for a year ago?

going to ranko, had post price present lensky and reservations about him because he still believe this presidents will lead you crying to victory. conflict the next on d. w. who landscape with aspiring germany's volcanic mindful regions about 10000 years ago. the volcanoes went quiet. com is something green again. the underground into o is on d w. the shannon, the award winning offer is available language

and has never been sent to and so you don't feel the same way you expect and want different things from life than your parents. i just want to pursue was that's my thought. fired, or you think your kid is 2 different risk, irresponsible, unreasonable, or stop porters those nonsense? i want my son to become a doctor. is there an alternative plan? everything to prevent a divorce, but nothing worth showing because it's time you were asleep and we paid for them when generations

this week on t w is kind of fun. i feel like they're the ukraine approaches. the 2nd that of us say, of russia is full scale invasion with some alarming uncertainties. will the us be able to restock the items? and i munition supplies which drive out a month ago, have the big promises from the west about staying with ukraine as long as it takes time to dust. my guess this week is alexi gunter and co. you creating an m p and delegate to the parliamentary assembly of the council of your one thing shouldn't be clear for everybody. ukrainian people are fighting about who we are losing people every day. and we come to wait forever and we can fight forever for a year ago. going to run co head but.
