of the experts believe the protests, which they say are largest in serbia in decades now present the biggest threat to the present in voltage 12 year rule. that's all the headlines for now. the ground for doc film that you can, i'm on any so thanks for watching the why do, how many does not get drunk? why do grab a tasteful waves, squeeze all bodies. how much do we need a day to stop fun praying for help find beyond this gets much on dw science, outtake talk channel the

it's the biggest mass extinction since the dinosaurs disappeared every year. countless species are with us. but is that permanent? the, we're going to have to deeper into the past and bring some of these really important species back. it is hope the technology will enable this, not the right you know is need our help and i want to help somebody, i can help them. and the aim is to give new advice to the genetic material of dead animals asking us who is financing this? what are the motive? some isn't the money needed to elsewhere? that's how things are progressing rapidly and laboratories around the world. our goal is to have our 1st man with cast by 2028, fill us in the us and we are opening a pen doors box and have no idea what to expect.

the, the this is not a z and her daughter far to, to northern invite rhinos, the last of their kind. this b c's has been almost exterminated to harvest their horns. the 2 females are guarded, round the clock at a fenced in sanctuary. and can you in the wild, only southern white, right? those are left. they are related but have different language and genetics. the last northern rhino both died in 2018. so there can be no more off spring. when nodding and 5 to die, an entire species will become extinct. nothing more can be done. for canot.

experts in prison are not yet admitting defeat the tax payer funded like minutes. institute for zoo and wildlife research leads the international scientific consortium by a rescue reproductive medicine specialist thomas. his the behind has been the head of this project since 2019. which aims to prevent the extinction of the northern wide rhino. but i'm, i'm is, i'm the was the way you work to save such a large amount on your face with almost unsolvable problems. and have to develop completely new approaches, fairly familiar on that settings because the cry laboratory for decades, researchers have been storing tissue samples here, including egg and sperm cells, from 300 endangered animal species. it's like a frozen zoo. the cells are preserved in liquid nitrogen in a kind of hibernation,

stayed at minus $193.00 degrees and sod as required. they include sperm from 4 northern white finals. that guidance is these samples are crucial for to invest as a bond. and susanna, what's the next half thing for trees from far to and magazine? these will then be fertilized in the laboratory with the preserved sperm of the dead rhino pulse. an embryo develops in nutrients, fluid, and as implanted in a cow of the related southern whites for analysis. in the womb of the server gets mother, the embryo develops into it right now. some risk calf that is born after 16 months . as soon as possible, the little one will then be placed with thought to or not seem to be brought up.

the it is an experiment on wild animals that have a special significant that's nice on is the final service, is a key students be fees, which means that it's at the top of a hierarchy of entire species communities as high says the best scope of the young man is really hearing an ecosystem by bringing back a keystone species is a very important element in repairing the planet, need to be the intact to become the his events mission began in 2019. and can you all project a game reserve, the vet for repairs? the operations it's a race against time. the calf has to learn the behavior of its last 2 living species, members before they die. the in the 2 females can no

longer bear off spring themselves. you can fall to born in 1989 has cysts and inflammation in her uterus and her mother now jane, who was 11 years older than her, has injured hind legs. however, both are still producing healthy ex side. now how she looks, i think you did a very good job to keep her home. this is mobile. i left 3 bought so vivid, analyze her black and, and 6 of the kind of meet the hundreds of kilos of equipment have been flowing in. the experts have gained a lot of experience to similar procedures on to animals, but they do not know how a wild animal will react to the removal of x. the fact, too is under anesthetic. her heart rate and breathing are being monitored. the procedure

being performed by his plans team is risky for the animal. since the sexual tract of a female rhinoceros is like a labyrinth, an ultrasound prob, helps to monitor the operation the, the specimens, look healthy. the female rhino is on harmed and recovers quickly. her eggs take a long journey to europe, to a special laboratory in italy. the wide rhinos still have habitats and could survive if they were not hunted.

according to studies, human influence means that species die out hundreds of times faster than they otherwise would. and there has been at least 5 major species extinction events in the history of the earth. about 450000000 years ago, the sea level dropped and the planet became bitterly cold. 85 percent of species died after which many new ones developed. the next event was massive volcanic eruptions, oxygen depletion, and the oceans that killed off almost all life. an asteroid impact triggered the next disaster. a good 60000000 years ago, a media right crushed into the earth, followed by earthquakes. and so now me is, the sky darkened and the planet became extremely cold. almost all dinosaurs disappeared and this event along with many other species

can we bring back dinosaurs like into a rustic park? probably not because their genetic material has decade over time. but the last mamma died only around 4000 years ago. is there any chance of reviving this species without using preserved selves as with the rhinoceros, as in addition to the deterioration of their living conditions? hunting by humans also played a role in the extinction of these ancient elephants. the all that exists now are fines in the frozen ice of russia and alaska. the idea of resurrecting them has been discussed for decades. for a long time, however, there was a lack of sufficient genetic material and methods to replicate the genes. this is

now changing the following ground in siberia has repeatedly re sealed well preserved specimens. this has made it possible to reconstruct completely the mammoths genetic materials from tissue bones and provide in dallas in the us. a private company wants to take the next steps. colossal bio sciences has been working on the extinction projects. i eat the revival of extinct species since 2021. more than 60 scientists are involved in this research. the $225000000.00 us dollars of company capital comes from investors, including a company financed by the c. i. a colossal bio sciences states on its website that it is committed to restoring the earth to

a healthier state. they want to revolutionize history. i'd be the 1st company to successfully apply modern genetic engineering to extinct species. the brains behind this project, our scientists, george church, and entrepreneur ben lamb. we saw an opportunity to one bring back iconic space, sees that humans had a role in their extensions in were kind of undo the sins of the past. we while the back into the eco system and partnerships with like, indigenous people, groups and private landowners, and governments, as a way to help restore egos, systems in on the path to that. we want to build technology that help modern conservation that can be applied today. colossal flagship project is the mammoths. their closest relatives are asian, no offense whose population is declining because their habitats are freaking. the idea is to open up new areas and colder regions for this

b. c's. thanks to ma'am of genetic materials. the only reason we're looking at a incidental in this case um, under that framing at least, is because those elephants were exceptionally called resistance. they, they could live for months at minus 40 degrees. so, so, so that's a, as a rear resources we want to exploit. genetic material, the asian elephant is 99.6 percent identical to that of the minus the remaining 0.4 percent will be covered by a new type of technology cert. gene segments are removed from the genetic material of a fertilized egg cell of an asian elephant called using crisper gene scissors. with the artificially recreated dna. the blueprint of which originates from mammoths genes for will be here and the sick layer of fact can be precisely implanted into

the genetic material of the elephant cell via electrical stimulation. the manipulated accel grows into an embryo. it will be planted in the form of a surrogate elephant mother. the spring will then have the cold persistence of a bully mammoth, and will probably look like 12. magnets and elephants carried the young for 22 months. it would take a long time to produce these hybrid creatures, and it would take many surrogate mothers. maybe too many we're working for a variety of reasons on developments outside of the elephant, spotty to the, you know, from embryo to it's a newborn, ex vivo and artificial looms. and that sort of thing is best possible. in 2017, a team of american researchers managed to grow premature lambs in a bio bag,

a type of plastic bag. since then, many scientists have been working on developing artificial bones. the most doub. ready centers uh, throughout the arctic where they will be born right near where they're going to be so you don't have to. so the floor is, uh they just, they walk out the door of the lab and there where they belong. and this is where these mammas elephants will graze. inside periods, former mammoths step work raising animals are scarce, and forests are now growing in 2018. george church made russian biologists survey zima who has been running a special research station there for decades. an ice age park. he has settled by some musk ox and wild horses over a large area. why?

the urban wars scrape away the snow to find food. they remove the insulating layer of snow on the ground. cold air reaches the soil and ensures that it remains frozen and does not saw. this means that less stored carbon dioxide is released from the soil into the environment. man, that's good, therefore help to protect the climate. however, this would require thousands of colossal bio sciences laboratory animals with them that must colonies be good for the natural world. at present and back natural history. museum in frankfort, contin boone, and gazing researches by a diversity i the relationships between animals plans and their habitats. to smell, and you should be able to see a really wild experiment which had part of see the mamma says parasites and has an impact on the vegetation, the one that gets there are competitive relationships with other species. so as of yet, it says if we've been threatening the colossus into

a complex network and as effects all the other, it's red. so we can't predict in advance what will happen find i hope the falls. so last time it puts it on the return of the quad that is being worked on in south africa. there are also plans to recreate the american passenger pigeon. there are no known plans for the joint. ok. the situation is different for the slight less dodo researchers at cologne. so want to bring back the bird that was wiped out by human, introduced rats. is vito of some lead me of a bringing the cool things to pieces back to life is obviously something that fascinates people and it's understandable less we can put save and bring back what we have lost. that's known to look cool. investment for the one hub, but in terms of protecting bio diversity, it's a tiny drop in an ocean of problems would see on from putting according to studies up to $58000.00 speeds, these become extinct every year. their genetics are lost and they leave gaps in the

network of relationships and their habitat. the excuse me, up and we have some more species. we have the more robust and stable eco systems are female. this means that every time we lose the species, we weak in this network of life. and this creates uncertainty, and i'm interested in all ecosystem functions that we obtain from nature are becoming increasingly difficult to grasp and produce really go too fast and on support to see on the rescue of the rhinos continues in northern italy near the city of cremona, by a rescue research consortium includes up until a leading specialist laboratory for horse breeding. the experts are working on combining the genetic material of highly productive farm animals by since horses are related to rhinoceroses, much is also similar in their embryonic development.

this is why all of the northern wide rhino eggs from kenya are brought here to be fertilized. but the researchers are breaking new ground with these wild animals, missing the guns, but not to discover the very specific requirements that the writing officer has. embryo has identified these long series of test when months of the summit, exiles don't tolerate fruit to has some glucose cause. then you have to find that out cuz they're not on lots of small things, but they have a significant impact on compared to horses. the number of eggs obtained from the 2 runny nose, a small, and not all of them survive transportation and the procedure before they are fertilized. the embryonic drum cells still have to mature at a constant temperature. embryos are produced here not only from northern wide rhinos, but also from the more common southern species. the researchers want to practice

the embryo transfer method on these animals 1st. 2 thoughts from from deceased rhinoceros bulls are injected into the excels dx then divide regularly in the incubator until they are sufficiently multi cellular. the state of growth is interrupted after 8 days. the, all embryos are then stored in the coal chamber for later use in kenya.

in the old project, essential wary embryos use is 1st being tested on the southern wide reino. this is why mother nature comes in of the as well as the surrogate mother. as the bullet has also been selected, his presence stimulates the females and indicates whether one of the partners is ready to conceive. the bowl has been sterilized, as he is not supposed to father any off spring with a surrogate mother. if meeting occurs, the researchers only have 6 days to implant the embryo created in the laboratory into the call on september 23rd to buy a risk to researchers get ready. the

vet has to get close to the female with the anesthetic gun. this is because the range of the dart, which is fired using air pressure is short. the the a nice to ties for nasa risk how is immediately protected from overheating, physical ads and holes that have previously tested 13 embryo transfers and runny nose into was and on farms each time and successfully. they have developed all the methods and technical equipment for this. b c's themselves with this needle system is a punch, has to be careful not to hit any of the large blood vessels. when inserting the embryos, the rhino survives the procedure well, from now on, it's

a case of waiting m. c. and kenya, berlin and simona to buy a rescue consortium is working to save. the rhino support is now also coming from dallas. the private consortium colossal is not only working on providing the mamma is also seeking partnerships with other scientists. it has been cooperating with the berlin institute for zoo and wildlife research since 2023 from was on the. it has to be said that companies like colossal work closely with us and provide us with technology is developed for our needs, belong to. so for fuel se, besides that, in addition to their efforts to bring back the madness which they are helping us in our contribution efforts to use these highly complex technologies for the northern white drain of looking for that's not clearly applies monassa. and that is, that's the american company,

as particularly interested in the experience gained in be productive biology. you have to have all of the top experts. you have all the special is. if you have a bunch of technology, then you need a lot of infrastructure. so, you know, we, we raise $225000000.00 to go uh, support this uh, these initiatives. um and then some of the technology that we develop that have an application of human health care. we're monetizing for economic returns. colossal itself is a colossus among high tech companies. the biotech company was valued in 2023 and $1000000000.00 in the german university town of tubing. and the biologist is investigating the effects of the work involved and reviving extinct species as an independent environmental f assessed to ease advises authorities and universities. should we spend a lot of money on mammoths projects?

this i didn't get to the fact that someone is money, but something is not a bad thing per se. but of course, the question is, who is financing this and what then move to see if this might the money not be needed much more urgently elsewhere to bring in that problem. until now, environmental organizations have spent a lot on preserving protected areas. the modern approach of investing large sums and the return of exchange animals might not always aid the rather conservative approach of preserving living species. this gives us losing always the risk that in the hope that we can simply rebuild everything against the assets that would have to be made to preserve bio diversity. now will decline, knock that we will put enough human and financial resources into it and say, well, once the next thing we'll just rebuild them again, i think i know the progress is any other concern is if you can repair like this, then you won't have to worry about is

a tall he like that because you can repair all of the amenities. mistake all that that's, that's nice. i don't think that will be the case because it's simply far too expensive . this and the experience and extreme expense, the commitment in terms of scientific technology hours, it should be the exception, the to the ultimate sizes. and even now the rescue efforts for the rhinoceros would hardly be feasible without funding from german tax payers. funding for nature conservation is limited, we're not taking capital away from conservation. this is new money going into conservation in all of the tools and technology that we make on the path to the extinction or giving to the world to governments to non profits. other engineers for free, so any non profit can use our technologies for spaces, preservation, and helping save critically and danger or other endangered species. colossal has also been supporting researchers in australia since 2023. the focus there is on an

animal with stripes like a tiger that a had similar to both. it was once the largest carnivorous marse appeal on the continent. with a set of teeth to prey on tangles and wild rabbits. the silent scene is also known as the testimony and tiger. this film footage shows the last living specimen and a zoo. the after sheep were introduced to tasmania farmer, saw tasmanian tigers as enemies, and hunted them mercilessly. on september 7th, 1936. this animal died and with it, it's the seas. the remains of animals from use are stored at the museums, victoria and melbourne. curator kevin ro is interested in the

survey, and tigers are a symbol of extinction and loss and australia. and as we know, australia as the worst the extinction record from mammals of any country on earth with a 30 species last sense, european settlement and australia that has me and tiger is gone. it was an important predator on the let's try and landscape. and if we care about the functioning, where eco systems, we need to sustain the top predators in those systems. this man wants to help geneticist. andrew pass from the university of melbourne. he wants to revive the file a seen. others have, have the same idea in the past, but past is now being supported by colossal, with millions of dollars, and has newly developed technologies at his disposal the scientist or sifting to the largest collection of the timeless scenes in the

world. 80 here, where there are specimens of 32 of these animals in the melbourne museum. this invitation that we're hoping that from some of these basements, these looked as if they some really nice insect a united day. and that we can sequence that entire gene. i'm of these animals and that really gives us the blue printing to the building blocks of what we need to recreate and bring these animals back home embryos preserved in alcohol, of which there are only 13 worldwide, 3 of them in melbourne. remarkably well preserved annual task also take samples from the specimens the and testing on itemized the embryo labeled see 5757 is over a 100 years old and comes from the womb of a female preserved in the museum. it is well preserved and therefore

a promising candidate for pasco plans. we still con, create life with the east mountain. so the way that the extinction works is you have to begin with was. so what you do is you has to be able to get all the data nicely queens of your experience animal. and then once you have that, you compare it to own living animals to find what is the closest weaving relative of the existing spacing embryo. see 5757 is the breakthrough in 2018. the blueprint of the tasmanian tiger was almost completely reconstructed for the 1st time. now andrew passed got his team, begin their search for genetically closely related animal. the researchers at the university of melbourne have succeeded in finding a close relative of the tasmanian tiger. the

fact hands narrow footed most po, mouse for gunner, which hears ancestry with the testimony and ty, for a comparison of its genetic material with the reconstructed dna reveals and astonishingly close relationship to the large creditor. the laboratory mice have many advantages for the project. the small animals are relatively common in the wild and have a short gestation period. they reproduce well and are easy to keep. this doubly valuable for research, special stylus in genes can be introduced into the cells of the done or using gene scissors. the fingers on carnivores are also suitable a surrogate mother is that carried the embryos of the testimony and tiger there's obviously a messy sized difference in the lots to do. it has many times,

but this is one of the fantastic things about my see if it was these when they blown they, oh, really, really small. so that means when even i've done a could just fades and do best to a baby ties my name till i go. whether done or koala or kangaroo. the embryos of all marsupials are about the same size and the room usually barely bigger than a grain of rice. they august birth to their off spring at a very early stage of development. after the to station period, the young crawled out of the birth opening. in the mothers of domino for they should meet to the pouch climbing and attached themselves by the mouth to one of her teeth. well protected the young animals mature. it was the same with the style a scene which genes make a testimony and tiger tasmanian tiger. pictures of the skeleton and organs have been taken of all of the embryos past,

concentrates on typical characteristics. this note the job, the strong hind legs, the or in comparable predators, such as the dog blanketing. though he finds dean regions that are important for hunting prate, and these could also be decisive for the reconstruction of the test median tigers. dna the researchers are studying which introduced has manian tied to a genes trigger, which changes using embryos manipulated in the laboratory that came originally from done arts. there are still many unanswered questions, but knowledge about the various stages of development is growing rapidly. the 1st has meaning and tigers could be born in the next decade. you michael, of those changes the beginning, you will have a complete so i listen. it any differences that you would have from any wall follow

the same? would be about the same, but any to animals in the fall listening population would have from each other all you and all i would have from each other. so at that point, i think you genuinely have us all of a sudden, but you've been, could put back into that eco system. it has not yet known whether the genetic makeup of assign the scenes will be sufficient to enable them to survive in the wild. the should reconstructed animals be released back into the wild at all. such as surface old is so to speak, the decision maker as to who may live and who must dine interest. first is not the decision that people make, but one that they are overwhelmed by and finally, politics can now decide who can live and who must die even off wants us to have most. we manipulate the landscape way of playing gold when we drove the sentiment to extinction in the 1st place. we was certainly playing a band. and so i think what we're doing now is trying to correct some of those

mistakes we made in the past. that would be extremely arrogant for someone to claim that uh no, we're just playing. we're not even playing. we're working at being engineers is what humans have been doing since we became humans. we study the past, we plan for the future. we invent things that we're just doing our job. that's all is on a higher than voltage, such as a steam reference respect and humanity are completely lost if it's the complete opposite category. because our going to say we can make what nature has produced ourselves. no longer seeing that perhaps we is part of the whole. i'm not in control of things the way we would always like to bring any so in the hunt, come do that. and again, present. so is it the case that we are not only making corrections, but we're also opening a pandora's box just being of, i'm sorry, going to be unless, than this noise between you and this molly form, this leads, so not been named us plus the fundraising bundle from then t,

and in was the in clear log on once in form, from leaving. and let's say i have fun this weekend us, we go to the, i'm on my find out what's my babies? here's atlanta is also working with an extended work center in berlin to generate tests to bind all services. the research into stem cells is being carried out here. to create healthy excels, the, let's see if it has grown cultures of skin tissue from 12 northern white finals that died in sue's, the living cells from tissue or blood are removed from a rhinoceros and preserved. they can be returned to an embryonic stage at any time using a cocktail of genes. the stem cells are then all wrong or cells from which any body cells can be cultivated. the certain

start or proteins are added to stem cells mature into sperm or ex cells and a special culture medium. once researchers have successfully produced the mature accel from the skin cells, this is fertilized with frozen sperm from deceased mailed the, the resulting embryo can be implemented in a surrogate mother. the related southern white for an officer us on the cap. she's carrying. the advantage is that the artificially produced excels can be used to increase the genetic diversity of the future by no community. the research was, would no longer have to rely solely on the again, needs of the 2 closely related females. however, they must ensure that all the aids used to nod alter the genetic material of the egg cells produced a man is miss thompson,

the glass toner has made the stem cell. i carry out very thorough quality control to make sure that there is nothing in there that doesn't belong. bias must be all hunger as long as after all, i want to have a healthy right now at some point, and not feed something genetically modified. you're the mrs. missed of blood, it's not the aim of my work line i've, i've so far it has only been possible to produce excels precursors. they only mature when they are surrounded by a very in tissue. however, it is not possible to obtain this from living or deceased rhinos. the nourishing cell material must therefore also 1st be cultivated then you do some a t, but we have to use this method. it's already too late to do anything else on the on non crop. then all other traditional species conservation measures have failed. as we boy, it's simply the last chance to save the species this and we see it as a blueprint for other species that are similarly endangered. is insights flow

pauses. another often be english if edits and time is of the essence, because almost all or by no species are endangered long plus the so in the long term of a whole herd could be re established this way for let's see. one is this individual good news from kenya. the surrogate mother of the southern white rhino is pregnant and the embryo has been growing for 2 months. the in december 2023. however, heavy rain sets and as a result, bacteria from the soil are flushed to the surface. the surrogate mother dies of poisoning and with her the embryo. the of the researches from berlin are

left with only the dead fetus. the artificially created embryo lived in the room for $62.00 days. it was male and already 6.4 centimeters long. the the tissue samples as well as ultrasound examinations review, but he was perfectly healthy. the there was a 95 percent chance that the baby would have been born after a total of 16 months. the most ideally mixed feeling because we had never such beautiful it did is i know in all and but on the other side, we would strongly prefer that it just in the you to us and going to the little ones

that are a good mother was also healthy until her bacterial infection, the procedure had not harmed the mother. this lead in me is fetus. with my head was a really emotional moment, but it's on so the presents and problematic scientifically to break. so the successful effort will be presented at an international press conference in january 2024 including a 3 d model. 2 is our baby, the it has the name, the number one. now the team wants to implant a northern white rhino embryo into a surrogate mother. that is really a milestone to allow us to produce most of my time to cops in the next 22 and a half years. the success of the international by

a rescue team is exemplary. top researchers from all over the world are working on scientific benchmarks for future species, conservation in the tools that you need to do the extinction to bring an animal back exist to that. you said there's no magic, there is no, no technologies that we need to develop in order to make this a reality. the methods are getting better and better and a lot can be achieved with a lot of money. but they see that there's a lot of exciting spaces that could be very adaptive in the modern world. we just want to be very cautious that you don't create an invasive space. it remains controversial, whether there should be any new old species at all. i remember you and i 1000000 species threatened with extinction. second of we know exactly what needs to be done to save these pieces. that's who i'm going in there. now it's such a technological solutions as well intentioned, and fascinated,

but not really helpful. that you should find whether biotechnology can now save nature remains controversial. i'd also like to, i can't see this as a contribution to nature conservation. describe with around the be to address the drive of the destruction of nature, done reconstructing individual speeds. the spend $100.00 or will it make sense to preserve nature and reconstruct animals in the future. we are into the funnel as this we, we assume that we will repair what has broken in the past and hopefully not have to repair what will break in the future, who comes up with good she even has value engineers were able to produce northern wide find no caps again. these animals need intact habitats should other extinct species also return. the debate will only really get going if and when the 1st mammoths envelopes are actually board. the, the

safety issues that management mass lounge blowing is in crisis. the us aircraft manufacturer is highly indebted, and moral and image are to in the all time low. is this an opportunity for it to your opinion? rival airbus made into many see minutes on the w. y. have quite asked a story. i scroll down for

a movie like almost fly this all over the label. i'm really good at being almost done. police police pointing, mostly part of that. definitely got people thinking bought it goes out for basically, you know, for a little that the more than a few items somebody got to come over at west point in the ceiling, come with the effect in 90 minutes on d w. the reason might say the way growing up in a country with no prospect, the boss in 2090 before the rest of the 5 young people of searching the way and dream vacation to the human they is

we will not say the way starts february 14th on dw, the, this is the news, and these are top stories. countries and organizations around the world have overwhelmingly rejected president donald trump's plan to quote, take over the gaza strip. trump said the ravaged were ravaged coast strip would be redeveloped in quote, the riviera of the middle east, well, palestinians would be resettled elsewhere. the white house later described the relocation as temporary. even many us allies say trump idea violates international law and disregards a 2 state solution to the israeli palestinian conflict.
