place because i'm responsible for the future fall country for the people behind the boss. sh. gardens of truth starts february 18th on d w. ah ah ah, this is deed of the news live for lead. the pentagon says is to check it a 2nd, suspected chinese surveillance balloon over latin america. the 1st one, floating above the u. s. heartland ignited a diplomatic storm that's kept the secretary of state visiting china. plus more military aid from the united states for ukraine. the latest package,

nearly doubles, keeps striking range against russian forces which continue attacking ukrainian strong. and it's spearheaded to fight against coven researchers now say a new technology could become an effective weapon against cancer ah unexpired. welcome to the program. the pentagon says another suspected chinese spar balloon has been discovered this time flying over latin america. another balloon was seen floating above the u. s. heart land spotting his complicated washington and bay jenks already strained relations and drawn americans attention to the sky. there is floating high above the united states on this balloon is causing major diplomatic problems. back on earth. thing is after this guy, 1st spotted over montana by curious residence. it's now believed to be

a chinese espionage platform. last 35 minutes about china's decision to fly and surveillance balloon over the continental united states is both unacceptable and irresponsible. that's what this is about is a violation of our sovereignty. it's a violation of international law. china rejects the spine claims and says it's a weather balloon that's veered off course. the white house isn't convinced, and a plan diplomatic trip to beijing has been abruptly called off. what this is done is created the conditions that undermine the purpose of the trip, including ongoing efforts to build a floor under the relationship and to address a broad range of issues that are of concern to the american people. i believe to the chinese people and certainly as well to people around the world. the trip was

expected to be a significant step in improving ties between the 2 countries. the balloon deflating those hopes. while some americans are demanding it be shot down is balloons are so huge that even that kind of that number of any additions that, that amount of any distance that towards it is only going to cause a very, very slow leak and was not wanted to come down immediately, you can't just talk to the balloon and it's going to go away. while the pentagon says the balloon poses no physical threat, it's no doubt doing damage to us china relations. relations the u. s. is determined to strengthen amid rising global tensions. united states has announced a new weapons package for ukraine worth $2200000000.00. it includes new longer range missiles which could double the distance ukraine can strike and put russia supply lines in eastern ukraine within reach more armoured vehicles in the air defense systems are also being provided. the latest package brings the total us

support for ukraine. since russia's invasion to more than $29000000000.00, the aid comes it, keeps forces are struggling against and intensifying russian assault on the city of back moot, ukrainian president. a lot of years ago, he says his forces will hold back, would quoting now, for as long as we can up until now the u. s. is declined to send ukraine longer range missiles for fear of provoking russia into escalating the conflict. so what's changed? the question i put to military analyst frank lead, which well, nick, the message that you created asked for to called attack homes. they're still not getting what they are getting are something called the ground, launched small diameter bombs, which about half the range of those for about 93 miles, a 150 kilometers or so. and you yourself him to that purpose with the high mouse to which these missiles are designed to oriented the other launch system down to 70

multiple loans, rocket systems. the russians have realized that clearly they've had their logistics wrecked by these over the last couple of months. is mostly deals with, appreciate it, so that move those logistical basis further back behind the lines. the problem of the russians now is that these long range missiles that ukraine is getting 150 kilometers will now challenge those. and that's really important actually, because what it will do is force to russians once again to push back their logistical chain way back behind their lines if they want them wrecked again, as happened in october, november, december. and just if we may get to back moved, were intense fighting as it is continuing. president zelinski saying ukraine will fight for as long as we can. how long will that likely be to think okay, couple of things here as yet the russians have not got into the town of bath, not itself. it's a real dilemma for the ukrainians will fall by pretty inform commentators and

at least one west intelligence service that the american civil ready advised the ukrainians to, to withdraw from baton on their own terms. just in case they get surrounded and they can't withdraw on their own terms withdrawal and defies very difficult. it needs a lot of planning. so the, the calculation that you credit commanders have to make journals, albany, zelinski of course, and some of the subordinate commanders is whether it's worth holding on as long as possible and measure enough against the huge cost. at the moment, clearly zalinski indicates they'll be hanging on and just for the bigger picture, if i may know, i know you're not in jo biden's head, but is it fair to assume that washington calculated that? losing back wooden desk is a bigger risk than escalating tensions with russia in terms of, you know, providing that extra new weaponry. yeah,

i don't see escalation is a real risky. i don't think it's part of your calculations except in so far as the getting the sort of compromise rocket system rather than one asked for much longer range attack of box itself is only important strategic in the last of don't ask because of the resources that both sides are put into it and it's a perfect example of military, some cost. in other words, it's important says it derives after the losses that both sides i've taken so far and that they're willing to expend, to hold on to it. it has no other intrinsic strategic importance, say, as it will give service of ours and give russia a small town. we have taken 6 months to take our boats. very l for them, for the much larger targets beyond suits, labianca crime, a task ok. military analyst frank lead, which thanks so much for that insight. thank you. that time for a brief look now at some other stories from around the world. i see and foreign

ministers meeting in jakarta have urged me in march to implement a peace plan. agreed with the block in 2021. in more was banned from attending the meeting of south east asian state. in mars, military plunge the country into chaos went over through the democratically elected government. 2 years ago. authorities in chile are struggling to contain deadly wild fires that are sweeping parts of the country. so far at least 13 people have died and over a 140 square kilometers of land have been devastated by the blazes caused by heat waves in the region. hope francis has met with victims of a civil war in south sudan. thousands of people streamed towards the cathedral and juba to see the pontiff. earlier. the pope made an impassioned plea for peace to warring factions in the country, saying that history would judge them harshly if they further delayed implementing a 2018 piece accord. the international community is marking world cancer day. cancer is among the leading causes of death worldwide. but now thanks

to a cutting edge, coven vaccine technology we might just might be closer to stopping cancer. germany's bio tech is launching a trial and united kingdom of personalized cancer vaccines. this autumn, or on the technology in this upcoming report. during the cove at 19 pandemic, vaccines were rolled out within a year faster than most experts believed possible. and messenger r n a vaccines were among the 1st to gain approvals, they work by giving the body's immune system a preview of potentially dangerous invaders. a dose contains many copies of a short stretch of precise genetic information. the messenger r n a. it induces cells to start making proteins that are otherwise only found on a specific pathogen, like the proteins that stud the surface of sars covey to the virus that causes cov 19. then when the immune system encounters the virus,

it quickly recognizes the invader and wipes it out. categorically messenger, already vaccines have proven to be exceptionally effective. they have proven to be able to protect people against severe and life threatening disease, and consequently save millions of lives. there are different types of r, n a, but all of them are coating molecules and that code can be rewritten. that's why many drug developers describe renee as medicinal software vaccines that use this software have a major advantage over other platforms. their codes can be easily altered to also make other proteins found on other disease causing microbes, teaching the immune system, how to fight them as well. and are in a can encode for proteins found not just an infectious diseases, but also for instance in cancers. in addition to messenger r n a, a range of other

r, n a's play key roles and metabolism and health. so they also have potential as medicines . the cancer application is quite interesting because it is not a vaccine that will prevent cancer. but rather it is a therapeutic vaccine. it is a vaccine directed custom tailored to the cancer of the, of the patient. which in hanson's and directs the immune response to more efficiently clear the tumor around 20 or any treatments have been approved so far globally. and dozens more are in trials in a wide range of diseases. and for more on this, we are joined now by den milner executive director of access to oncology medicines coalition. thank you for joining us, sir. there's been, as you've been hearing high hopes for this m r n a cancer treatment. how different

just to begin at would it be from the technologies we now use to cure cancer. so great question. so currently, the technologies that we use are largely directed at to killing the tumor using you know, either general targets which is classical chemotherapy or targeted therapies, which we have for example, for long cancer. but in those targeted therapies, these are still molecules or antibodies that are manufactured and don't use the bodies on immune system. naturally, our bodies can fight cancer. many cancers are off and we never develop as catherine . these are mean systems take care of them. so we're moving away from the traditional approach of attacking the cancer with something exhaustion as to moving to an ar nay, or an internal approach, where we actually use the body's own immune system to attack those cancers and destroy them. at mr. miller, we saw, of course, how during the code pandemic, how quickly vaccines could be ruled out once they were discovered. can we hope for

similar speed with cancer as i think so, but i think there is a major barrier which we did not do not have with infectious disease and not choosing the target for an individual patient. as you have was described in the piece before this of the ability to target infectious disease is quite easy because it's a foreign molecule. it's a foreign piece of material that's not naturally him human body. but when we talk about cancer and personalizing the vaccine, what we're talking about is finding some piece of the tumor that's been mutated or changed enough that we can then target that protein or that molecule with the vaccine and destroy it. and so we have to pick through all of the bits of the tumor using sequencing or other very robust processes to find the target, pull it out and say yes, this is the best one for this patient and then use it. and that process at the moment is still rather tedious and difficult and expensive to do for each patient. and again,

our concept is personalized. we want to do it for each patient. so that's the barrier. really have to overcome is rapid target selection for patients with cancer . it just if we put the cost in the individualized treatment challenges, aside for a moment, ah, how long you think we'll have to wait for wide scale rule out. well, i think that, you know, the agreement that the british government just signed with violin tech 410000 patients by 2030 is very promising. there was also the agreement personality signed with materna using their sequencing platform. i think these are signals that this is coming much more quickly than it would have, you know, we've been working on these vaccines for more than a decade for cancer with very little progress. but now that we've sort of gotten through all the hard parts with cove, we've taken the vaccine to scale, we've distributed, et cetera. now we can focus in on what is the one last barrier. and i think these kinds of agreements are going to speed this process. so i would say that there are 4 trials reporting this year, one on melanoma 2 on influenza and one on herpes. and that melanoma trial will be

really crucial to see the results because i think if that is a positive trial, we'll start to see more trials on the back end. and we'll see more results coming out that are moving this forward for patience. ok, thanks for that. good news, dan miller from the medicines coalition. thanks so much. that's her news roundup of next report takes a look at the increasing go between rich and poor in germany. a mix visor with every day for us and for our planet. a is on its way to bring you more conservation. how do we make cities green.
