ah ah ah, this is dw news live from berlin. nobel prize for 3 pioneers of click chemistry. the role swedish academy of sciences on us, the trio for discovering a way to snap molecules together. a technology that could help make cancer drugs more effect. also coming up the you agree?

so on the fresh sanctions against russia, after it's illegal annexations in you, cried brussels promise, a tough response with planned penalties for moscow to include a price cap on russian oil class. how real is russia's nuclear threat president booted as well the west? any attack on russia, including illegally annex parts of ukraine, could provoke a nuclear response. weapons could be used at how likely is he to use the class e long mosque and twitter he wanted to back out of the buy out. now he's back in the wells. wealthiest man says he will purchase that social media company after all . and for the $44000000000.00 they originally agreed ah,

i'm god offers well come to the program. first, this year's nobel prize for chemistry will be shared by 3 scientists, modern meltdown from denmark and to americans. carolyn bazzi and berry sharp las. they have been recognized for the development of bio orthogonal chemistry and clicking chemistry, which involves attaching molecules together to create decided sampling. only the 5th person ever to receive a 2nd nobel prize. now here's what the chair of the noble committee for chemistry you on our quist are to say kit chemistry is her almost almost like it sounds. it's all about snapping molecules together. imagine that you could attach small chemical buckles through different types of building blocks. then you could link these buckles together and produce molecules of greater complexity and

variations. bear with me in the studio as little as from our science department to play it all down. click chemistry for saw a very much sounds like lay gold to me. so what, what, what does it mean? it does. so they go to me as well. and actually that was the picture. a 1st set of mine, that sounds like a game, and it's kind of is because it's, it really, yeah it, imagine lego cubes. you have a yellow one, you have a blue one and a green one, and you can click them easily together and build something new out of it, right to house or whatever you want. and that's a click chemistry with molecules and in very tiny dim dimensions. so the lego cubes are molecules and you can again put or take different molecules and click them easily together. so the new thing now is that they found the, the click like no buckles as we just heard. embed was the, yeah, there was the new discovery they made and which made it easy now to,

to have new buildings, new molecular buildings and our yet in chemistry as a toll as a whole. what else on our bodies in our living cells, even okay, that sounds exciting. and that was a bit more about the, the 3 lawyers and their research. well, bearish, helpless. he was the 1st to discover the concept of click chemistry. so he had the idea that, well, maybe we could take these 2 molecules and kind of click them, it have an easy way to put them together. and, and this, this idea went all over the chemistry while it was really huge and many people and started to think about applications and to how to put this into practice. so that's where mot mother came in and he found the 1st reaction where that actually could be, could be applied where, where he could get pre calculus. yeah, exactly what make molecules clicked together and to use a copper as a buckle. now copper is a metal, and if we look at our bodies, metals too much too many, metals are not really good and they are too much metal,

especially too much copper. so the question came up, how can we use kind of chemistry our cells in our bodies and air that's where carolyn bare toes he came in. and she is living used as sugar, is over like a sugar complex as barcode and now made it also possible to, to click together molecules in our own body in living cells. now, how does all of this affect our lives? i mean, come out soon. well, can we sort of trick together a new, i don't know, kidney for me? well, the kidney. yeah. yeah, i think that's another part of research then. but the good thing about clicking molecules together is that you can also click something. it's a shiny molecule onto another molecule on our body, so you can make things shy and you can make things see in our body. and that's how you can track, for example, where processes take place where diseases develop, where drugs are or delivered in our body. if they go to the wrong place or to the

right place. so it really helped us in pharmaceutical development. it helped us in . yeah. and making new drugs, but also in materials research how to make more robust new materials, which is of course yeah. kind of needed in these times of climate change and everything else, but i think the pharmaceutical mm. yeah. things i've really that that's really the new thing. and that's also what, what are the laurie a to karen? but jose mentioned in her, in her speech after i, after she was announced, the winner of this nobel prize, la, i was there from a science department. thank you very much. we are showing some lie door to click chemistry. now the european union has agreed to impose new sanctions on russia. official said the decision ames to send us quote, a strong response to moscow's illegal annexation of 4 regions in ukraine. it's the blocks 8th package of measures against russia since president vladimir putin

launched the invasion into ukraine on february. the agreement includes and the imposition of a price cap on russian oil exports designed to impact the crime lab gremlins revenue. i'm not a sales on around the world just i know will not cut me off feet. so i've european union. the parliament has been also in discussion. the nuclear threats coming from russia as ukrainian forces make advances in the south and east of the country. that's concerned that russia may consider using its tactical nuclear weapons to hold a legally annex territory, will go to a correspondent in strasburg, shortly. but 1st, for more than nuclear threat and ukraine's advance. he is my colleague, a jose delroy with more details. well, just days ago, russia declared ownership of several ukrainian regions. but each day since ukraine has undermined those declarations from moscow with its victories on the ground. and

we can take a look at some of those now in the eastern region of dawn, yet they reclaimed the city of lyman and nearby towns. now leman is considered a strategic city due to its many railway connections, but it's in the south if they have really made some of the most impressive recent gains just yesterday in the regional hassan ukrainian forces claim to have pushed the frontline back by around 30 kilometers re taking the town of do chaney and regional officials say that ukrainian troops are moving along that a need for river recapturing villages as they go. well, rushes recent losses, a prompting domestic criticism of the army strategy, one of prudence allies that russia should now consider using low yield nuclear weapons. so with the threat of nuclear war on the table, what buttons could russia reach for? well, both the us and russia have nuclear thought pause of between 5 and 6000 warheads. and all of these, the u. s. mostly has large, long range weapons. but one 3rd of russia's stockpile is assumed to be so called

tactical warheads, which are smaller bombs for use on the battle fields. now, tactical warheads have lower payloads and shorter delivery systems, although they won't result in a global nuclear winter, they would still be devastating across a large area. so how real is russia's nuclear threat? while the director of the c, i recently said that there is no practical evidence of russia being close to using nuclear weapons. and other western monitors have also said that there's no sign of russia moving their warheads out of their bunkers. but now, every russian maneuver is being closely watched for any sign of where the puddings rhetoric will move into reality. thank you very much. so doro, there speculation, over russia's next move in the war was fuel this week, by a video showing a train in russia carrying military equipment. the british newspaper wrote that the

train was carrying these nuclear weapons that joel was just talking about. but defense expert half cast doubt on that claim. the video was posted on a russian telegram channel, which stated that was carrying armored vehicles to a specific russian army division. the same division handles, root rushes and nuclear warheads. there's no evidence that the train was carrying a nuclear ammunition, nor that it was heading towards cray. a little earlier, i spoke to conrad musica, his, the director of defense consultancy, russian consulting in poland. i asked for his analysis of that train footage. unfortunately, an analysis that we did to was misinterpreted and in many western outlets and wrote and which, which raised quite a lot of concern all across europe. i think. but essentially what this video showed was that there was

a train that was on the move and the trends carrying equipment which belonged to the 12th main directorate of the russian ministry of defense is director. it is quite specialized because it only deals with storage and handling and delivering of nuclear missions to russian units. the video did not show that the train was carrying any new nuclear payloads. at the time we did, we did not know what it was made. and we did not know where whether the train was moving to ukraine or out of your credit since then, more information was published. and we know that the trend was actually moving north east of moscow. so quite far away from ukraine and still you are not. we are not able to determine what the train was moving to your crane or not. however,

it is it a conclusion that the strain was carrying your class a lot and it was going to ukraine was definitely far fetched. and this is not something that we obviously wanted to achieve with our analysis. okay. now talking about the likelihood of the use of nuclear weapons by russia in that conflict. earlier we spoke to a military analyst who said, he doesn't think put in will use no to a weapon as it won't help him to win the war, but rather help him lose it. or would you agree? i think there are a lot of risks involved when it comes to nuclear weapons and i dont think that i and i also don't think that are right, that russia can know when this war are using tactical nuclear weapons. and we know that nato would probably respond, are it's debate all it's, it's debatable to, to what extent and how are, but i think it would only make a, make it more difficult for russia to achieve anything in this war. because i don't

think that you bring us will to fight out the defender ontario, she can be broken through a little tactical weapon, tactical nuclear weapon are released. however, the truth is that for conventional point of view, the only tool that russia heart now has available is men power. they do not health, they do not have any, you know, any special tanks, mariah crafts, more inferential fighting vehicles that can deploy into the butterfield to change the situation. so they can only rely on the mass of the russian armed forces door stop. ukraine on advancing in crucial parts of the front are if they will not be able to achieve doubt and with the man power. ah, i think that russian conventional auctions will run out. thank you very much. defense analyst conrad musica. thank you very much. now,

the security threat from russia is on the table as members of european parliament meet in straw's book. the u commission president also found a lie and has urged member states to stress test their energy infrastructure following suspected sabotage on pipelines, linking russia to germany last week. ah, and for more this, i'm no joined bar correspondent, mcsaunder, who is in strasburg, whether you will be in parliament is meeting max. what's the a european parliament's response to the illegal annexations of ukrainian land? right gad. so the, the overwhelming sentiments across political groups across party lines here, an inch ta spoken to your parliament seems to be that this illegal annexation of these 4 regions. and ukraine is indeed illegal. it's null and void. it means nothing but a further escalation of proteins war and ukraine and some,

any piece of even take to the point in today, a calling on the russian government or russia at terrorist state. so it seems that everybody here agrees that this indeed is a nothing that can happen that not is nothing that can be accepted and that ukrainians need for the support. there have been, however, some disagreements and what is the key priority here, right now? if you listen to the concert, a conservative group on there have been coals for sending weapons to ukraine for sending tanks and heavy every artillery to to ukraine and calling for germany and france to take the lead on this to join eastern european member states will done so in the past, if you look at the socialists group, for example, there is more a seems to be more of a focus on economic sanctions as they are being discussed and counts right now. and if you go even further left left party, there have been calls for diplomatic measures for, for talking with russians in addition to sanctions there. but a bottom line is the key message from today's debate is that the annexation,

the escalation of the war in ukraine is not acceptable. and there's no way that you will tolerate this, amex. what is the role of the european parliament in the warn you crying to the end, the member states of the final say well, that is directed to the european parliament as a one of the law making bodies. they can vote on laws that can greenlight them. they can vote them down, they can ask for amendments, they cannot initiate action. but what they can do is one of the largest you bodies . they have 705 elected officials from all across the european union. they can find a consensus, they can discuss these topics, such as the, the, the russian aggression on ukraine, and find a common line and a, and vote on this and send a strong message to, to, to the member states and mount pressure them to take action. no correspond mcsaunder there. thank you. are ukraine says its forces,

have retaken towns in the south and east of the country, including parts of the regions russia illegally, annexed last week. officials were installed by moscow and those regions of acknowledged setbacks in the castle region are correspondent when he has building, visited ukrainian troops in the south close to the front line as by looming fears of a cold winter. he found soldiers and local people optimistic about further gains they are digging in. the soldiers have only recently moved forward to the new position. now they are fortifying their defenses, repairing the trench if be more than 3 months now since ukrainian president volume is zalinski and ice cubes counter offensive in the south law, but we are constantly trying to drive the enemy from bad positions. with these attempts have been successful column and we are moving forward. we now have new

positions and we fortifying them. that is how we make a constant progress forward. you can shuttle from us for the for quite some time. ukraine's successes in the south have been less spectacular than those in the north east of the country. but recently, the army has been able to make significant gains down south as well. and the koreans are convinced that their tactics are more efficient and also more sustainable. and the russians there. but that doesn't mean moving forward is a walk in the park, though. on the la easy music, they just keep aggressively charging at us when us, they don't care about their own losses. garage and you get the impression that i just don't give a damn about their soldiers, that the doubles their tactics are simple, it's easy to read them or not but rash. this means that we have to be permanently on watch was video. we can never, ever lower our guard. he said that it was this bullet all those little bit lighter

bizarrely behind the lines villages have come under fire. russian forces passed through the settlement early on in the war later they were driven back. but since the territory has been back under ukrainian control, mission shells have been falling all over the place. believe british like that the in the beginning when i 1st experienced an incoming fire and there were explosions everywhere, i thought it would drop my house. i left the time, but when i heard that things had come down a bit, i came back. i repaired the roof because it started raining. then i decided to stay on stars. russia has seen tremendous losses of personnel and equipment. that's why president putin has started mobilizing more troops. but the soldiers here are calm, but the prospect of more russian reinforcements when i move it, nebraska call could you think and draft whoever they wanna. and however many they

want on you, but the ro, morales, and the opinion of the locals towards stumbling will not allow them to relax. jim that if will i with that a floppy just now the soldiers are preparing for winter, hoping that they can gain as much territory as they can for as long as the conditions allow it out he w corresponding mathias billing. i filed that report and he joins us now from mich alive and ukrainian forces, as we've heard in your report, are disturbed by how cheap the lives of russian shoulder soldiers seemed to be to their own commanders. good news, like that's a do anything to shift public opinion and russia. do you think the question is when they reach, i mean, no problem seems to be that in russia, the propaganda is working quite well and that people seem to be somehow as still either believing it or finding it more wise not to contest it publicly. but these

are not news or a russian lives that have been a bit put on. and i'd risk has been as a topic of this was in the very beginning when they came in to ukraine in the very beginning. ukrainian soldiers have told us that they were shocked at how little you are. russian. a command is value the lives of their soldiers. so this is nothing new. of course, we have estimates how many pierre soldiers, how many russian soldiers have died, their estimate by the ukraine and military, which puts them at around $60000.00, which is a huge amount considering that they have probably invaded in february with a number of about 200000 probably reinforced them then. ah, western estimates put them a little bit lower at 3040000, but still, that is a lot om, we do not however know for sure how many losses the ukrainian side has had. it has been a very costly war on both sides. now you have spoken to ukraine in offices and troops

. are there how important is it for them? how important is it for ukraine to gain more territory quickly before the russian mobilization takes effect? it's important for ukraine to take more territory, probably even before the winter arrives when it would be more difficult to move. but also it's important, of course, for ukraine and for the public morale in ukraine that the ukrainian army can regain some territory. because of course, this is, there's consensus here at that now that cannot be any compromise with russian territory issues. and it, ukraine needs to take all these territories back. the russian mobilization might, is nothing are such a big issue here because for most people, this seems just like russia throwing even more untrained personnel at the front lines and probably just making russian losses even higher. but expectations are

that this will not change a lot on the battlefield if it does not come with this strategical and also a qualitative change in the russian tactics. but here's that you gone, i can hear the i ride sirens, you better get yourself to safety. thank you very much, my to is billing of their reporting from mc alive. the tech bill in a long mask has apparently had another change of heart over his plans to buy twitter. tesla c o. now says he will buy the social media platform after all, for the originally read on price of $144000000000.00 to the father law suit over masks, attempt to back out of the deal take over, goes ahead. it will put the world's richest person in charge of the highly influential global social media platform. now, chris kolber from the w businesses. now with me in the studio, chris, what's the reason for this, you turner?

well, i think her illness notes are found out that he is in a very delicate situation. here he signed a legally binding contract by twitter, as he said, for $44000000000.00. but then one of the big out of it, claiming that there are far more many bots or fake accounts on the, on the website and twitter has suggested, but twitter said no, we have to, you have to follow through on this. we're going to take you to court over this figure that you claim, and apparently the chances for twitter winning such a trial to be, to be pretty good. also, such a trial might have put things forward of the law must, which he would have liked to stay private or at least concealed. so in the phase of possible defeat, we can assume he said ok, i'm you turning my, you turn. i'm going to follow through on this deal and by twitter for 44000000000 hours. now, what do we know? there have been lots and lots of speculations when the this, this planned transaction was, was announced. do we know what his plans are for today? it's a good question. i mean dylan musk has been complaining that free free speech is

being suppressed on twitter and other platforms. so possibly he could change policies there. but he's also a businessman, so we can expect that he does want to make money with twitter. in june, when he struck the deal to buy twitter, he said that he wanted a 1000000000 people to use twitter daily, which is quite a would be a steep increase from the 200000000. that that, that the, of the 200000000 active years daily. that the has, the site has today, and he also suggested that twitter could charge people to get verified to get the little blue check there. so those will be new streams of revenue up until now and twitter is heavily depending on, on people advertising. there are companies advertising there and those companies will keep a close look on which direction in mosque intends to take the company into. now chris, the alarmist, as you said, spoke about opening up twitter for free speech. what prompted that,

and what does he mean by that? we'll have to see are in it's possible that he will actually roll back some of the measures that twitter put in place to if not prevent, then at least flag fake news and, and hate speech long. musk and june reiterated that his stance to the platform is that it should allow all legal speech. it's his definition what that means. but he also seem to acknowledge that some moderation is necessary there. i think one indication of which, where the company is to go will be the midterm elections on november. 8th. should the deal, you know, go through quickly. what is the law must going to do then? is he going to unlock donald trump's twitter account or not? i think that could be a good indicator of what his plans were. twitter or chris grover from d w. business. thank you very much. you are saying dw news. here's a reminder of the top news story. this out, the

e u has agreed. a new round of sanctions against russia, of the most cost illegal annexation of 4 regions in ukraine. plant nations are said to include a price cap on russian oil. that's it from me and crystal and the new steam up next is made in germany. don't miss that gabrielle f, as in berlin for me and the new steam. thanks for watching. ah,

with who what of these mountains of waste could just disappear? sustainable packaging is urgently sought. bags made from algae, boem from mushrooms the future of sustainability. when will new

technologies become cost effective? made in germany next on d, w eco, africa? droughts are hitting rwanda. heard this here. now the government is taking action by providing free access to groundwater and teaching people how to use it to sustainably power with firstly, everyone is responsible for protecting jeff. secondly, we have to know how to use the water without wasting it. eco africa in 60 minutes on d, w o i might. and the pillar sticks in society,

taxes the right to loving taxes and the obligation to pay them both inherent in the sovereignty of nation states and their citizens. but what happens when the power of taxation is undermined? can't pay won't pay. taxation and politics starts october 21st on d w. ah ah ah ah, it's true that protecting the environment is off next pensive. the damage caused by .
