to see a wide spread race as depression today. history. we need to talk about here, the stories, shadows of german colonialism. the whole has a color and it's green. one german research team is convinced that algy can help solve some of humanities greatest problems around the globe. biologists are hunting for micro organisms with extraordinary abilities, like limes to creating energy, which might one day generate climate neutral cement. from 10 to 5 percent of blood black as far as seo to come some construction to the concrete production. yes. now here's a possible concrete substitute. that's the exact opposite. it doesn't produce c o 2 to absorb it absorbs in 12 for over

a year. we've accompanied researchers from kaiser's low towns, university of applied sciences to the depth of a spanish case where life on mars is being stimulated here on earth or in space. algae could be the key, doesn't come up 1st, go for a 1st name, and i'll give you all can take in waste materials and waste water and an extract nutrients from mann's office. we've very light and they can also produce oxygen. so as i can find the c o 2 we exile create to oxygen and food. same time on this. ok, a property amongst the best organisms for producing food. but i don't know the

as an expedition in northern spain, an hours drive from build out the these researchers led by biologist misha, lack of toast, are exploring a cave in hopes of discovering new species of algae and furthering their research on known once. they're not exactly sure what awaits them. there are almost 300 caves in this valley alone, and some 4000 in all of count abriya. one cave in particular, is of special interest to the german expedition team. the what they discover here is mind blowing. me sure. yeah. like a toast. finds organisms that bear witness to the very origins of life on earth, the kind of him, how much do you have just found

a huge patch with one of the oldest sonya in effects. henry aware are aware of the big cats incredible. i have never seen anything like that. it's quite incredible. i'm going to loss to what we fidget, clock about, right. what's left him speech list is how these bacteria known colloquially as blue green algae can survive with. so little light on one, we really want to discover the isolate new sign a bacteria and used in football, technological applications at the same time thought when we have in such a marvelous habitat. the 1st question is naturally, how would they survive it? so that's what we're doing is we're measuring photo synthesis with this device. but we're also seeing to what extent they've adapted to the light and how they utilize the unofficial parts for the algae researchers this can't of ran cave is

a god send a late person might just the most in booking, rock face. but for the biologists, it's a window into a fascinating world, an extraordinary multi generational colony. since you do some shopping, you can see these colorful surface here. these fluffy little gray green pads, they'll send you to these as i enter that curio. so with these yellow ones here, these pink jelly light clouds, this striking the arctic, that's the particular sy entered bacteria and we're off the glow. we go back to clear, we'll talk each one of the oldest leading cyan or bacteria and book to so it's a very basic primitive cyan, a bacterium that's living here alongside more modern spacing is a bit of a voltage differently. they're all leaving here in the colon included. this is like the misha lock, a toast and patrick young are thrilled with the wealth of research material they found and excited about the new questions that arise from it,

the existing dust. we know that they can survive without much lights 5, but we don't know exactly what the lower limit sees is also the question of how exactly this works in the low line situation. we've been counted deeper inside the cave, so i entered bacteria population. there is different than that if we found different species, a certain process is a different to you and or either. so the elegant here is quite class august responders and i can, yes, they can photo synthesizing the dog. we've moved even further into the cave and despite the total darkness, find species of algae living here to feel comfortable, you know, a 100 down and there's only 800004 line from above. can reach them as a volume allowances in the dog by simply structure that physiology about that photo synthesis. and so they can use most certainly the visible light spectrum. but 1st

industry, we switch the exciting of this and they may also be able to draw from further along the range of light in that and the random non or in the fall. right. and what the so got was looking, couldn't you understand that? it was spanish biologist, antonio gibson, who 1st drew his german colleagues attention to the case and sent them samples. it was the beginning of a great friendship between the spanish and german algae. researchers assigned him saturday, gumble a, you'll get tons of a new field of research. i find it very interesting in terms of the production and research of useful substances and materials. so it is not just the biological aspect which is already fascinating it and that's but it's also the practical application, something to not be taught to him. but i think in that regard, patrick and michael's ideas are in line with us. and mike and other words, if you think we're happy to continue supporting them on those, and we're looking forward to working even more closely with the you're gonna have

to pull them up. but instead of is that a, push it the instead of the money that as the spanish biologist works for a company that wants to model mars missions here, they've set up a space station of sorts. deep within the cave. the algae research conducted by the german team could also be interesting permissions into space, escape and come up if it's time to take on those that idea. and if you had to give them to lines perfectly with the original plan to draw on that potentially lease unexplored micro organisms like gap that all apparently capable of producing substances that have not yet been recess. and a to point out 6 rings to just a moment. so these organisms are in fish competition with each other. so they produce on 2 volts, especially if they're sort of these, most a didn't know, not incompetent yet. and today you are interested in it on a tv, i think like produce new tooth as a service, food for other organisms. so they could serve as food for special typically deal could all be possible. but english, i understand. he meant that the on,

but he said a change of scene. we had to the laboratory, a kaiser's low tones, university of applied sciences. the permits ends campus is home to the world, the largest collection of terrestrial fiano bacteria, l. t that live on the land, not in water. for study purposes, there being cultivated and liquid. nonetheless, over $350.00 species from all over the world can be found here in march this year or the i'm, for example here your advice selected cops at the offices from the i'm talking to the union sent you the how guys here we've isolated micro call us for it, like how go from very whole this of regions and a completely new outcome we've identified, even from sol involved in the auction, the auction attend to this country. what does that do? the, the kind of you have to do it has a small red. i'd a quite unusual that we don't know why it's the einstein as researchers started the

collection back in the 1950s. the algae from the spanish cave or the latest edition and could one day help us face the climate crisis. doesn't face it, the baby, couldn't somebody be covering it? there were some of that kind of caught up in ice, for example. cool. how they behave like rebuilding carl producing a sort of truck, he's kind of tennessee is one of our new projects here is to see whether we can use this as a submitted substitution as of the amendment as a can be crossed. and um yeah, 2 bucks. that's and then ease of old and who samples we collect tutoring here. do you think of something that tom, the german researchers are traveling the world on the hunt for new species of algae, the most recently spent 4 weeks in the add a comma desert, and she'll a while a whole spine. it's a cactus here. the other trend to police samples, that's a special type of like in that grows on the tips of the tech side in inverse this next prerequisites are extreme locations. it's very hard. and this little volta,

you will see organisms, they survive, that. they can also withstand very high temperatures in biotech, the logical react as, for example, on zillow tempo to an old phone. that's number one. and number 2, in extreme habitats like that to organise you always find organisms that can do something very special stuff, such as producing special active substances for adopting specific you metabolic pathways, stuff like the big armstrong, some algae enter into symbiosis with fund guy in order to survive and extreme places forming lincoln's patrick young, found such l. g, fungus, symbiosis, in the out of comma the fun. this becomes a kind of sun shade for the algae that is on the, on the, among other things. it also, it provides you the protection against the hush radiation one finds in the to comment is it is the l g e and not mobile. they trumped in a stationary position and somehow have to protect themselves from the sun's rays,

which they can't avoid with the like and like this ones that task falls to the funds will pump steps. they produce a sit and pigments in the case of these 3. she's those pigments that green is yellow in appearance. another key feature, the colonies survives on very little water. these are all properties that could come in very handy, say in the development of new products to reconvene, probably between 10 organic waste into plastic. early march 2022. the official launch of a research project called a waste to value the vision. at some point, l g will be grown directly on building facades and residents could benefit from the harvest. if bio plastics were able to thrive on such besides, it could also lead to growth and regional economies. all thanks to ality. green fuels could also be created using the same methods research as being

funded by the german federal state of rhineland to pull out nate, they see it as an investment in the future on gifts. the one that in those kind of heard of that on the state level, many companies would benefit from becoming a little less dependent on energy supply. as a credit, that's a significant consideration these days are no, we'd also be making a contribution to climate protection from here in rhineland class and it's about france. i was kind of hard to hold the german federal ministry of education and research is also funding the project. they've granted 8000000 euros for the 1st 3 years. several partners are working with the team from pam events. and it's also known to get caught up with currently enjoying an additional spock of interest move just hoping to progress as far as possible with the companies i think ultimately incrementing some of the only thing is we've been, we're searching for. yeah, so on this one, got it under forced tom. yeah. minds of yes, wonderful. just right. does the 2 researchers are unpacking

a new piece of equipment, a photo bio reactor. it will allow them to grow algae that normally live on land in liquid and thereby control the way they reproduce. a lazy thing. nothing is funny so they don't grow as well. documents, i think growing a controlled amount of stuff. i don't know large scale. this is that we can then control that grows here, and it kind of pre culture and transfer them into the loan to react with exact tooling. and soon analogy that's popular with biologists will be growing in this reactor as of somebody's peers. so these, for example, is the elaborate, difficult football technologist working without doing anything with the systemic assistance. it's used quite frequently and copes ideally and conditions like pass it within a few months. so that's what you see here. for example, it's the terrestrial out. can you write those internal stuff and score the multi cellular and spread like this as

a med center is feed them into you can see immediate time, they tend to clump together when you have to prevent that with this mixing process . yeah. when we're curious to see how we sound, be close and then we have no experience with it yet. the, the, the, the in vix this. so i'm on know, kind of follow that. you haven't tried yet. yeah. zoom a comp. so was it will take a do in here. we don't even know yet. we carry stuff as much fun. you're going to sewage spill that, you know, the, the reactor is an important intermediate step towards producing larger quantities of bio plastics or climate friendly summit. one day exist, and so this isn't close that window. she'd upset is a big difference between trying to force nature into the lab. that's to say, conducting experiments on a small lavar tree scale and being able to think on a launch or industrial scale and couldn't. that's a whole lot of botox movies and he's a student on us not 100 percent. that took the longest movies connection to its modules, the size of

a window the researchers have already commissioned them. the idea is to grow algae on facade inside these photo, by a reactors. if it works, the process could save a lot of waste and c. o 2. there are other benefits as well. some algy produced natural dies. some could end up on our plates and something. lots from your now we have solar systems on the roof can future. we could also cover the east and west for thoughts with these al give reactors. i then even collect this would regularly come by to help us develop for the whole we to all of a star cells, food order cabins instead of the essence. cuz a lot of research is still required, though space to the new research reactor will soon be housed in this former changing room. and we'll be back for a visit once the researchers have filled it with algae. for now, it's back to spain. misha locker towson, his spanish colleague,

have descended deep into the cave and reached the mar station. the aim here is to replicate living conditions on the red planet. as realistically as possible, the one day l g might be able to help space pioneers survive on mars. minds can cut so on about 10 not to go outside stuff up. so that's, that's a sign of x here. you can say can waste of materials and waste water and extract the nutrients from having a very different lights. like we have a light then compared to you. so could you put it in like in the volume of the c o 2 weeks hail to feed, creating oxygen and food at the same time by on? no, no meant to products in other, i'll probably be among the best organisms for producing food in the space and can embed. now let's see what the test ation in the spanish cave. the company hopes to approximate life on mars. even if some martian

conditions are impossible to reproduce, we cannot see if we need to take a look on the, on the on know tech by selling products. okay. the young thing would be actually to be a mass, not taking advantage that we have not the mass. why don't we come made mistakes, tyanne or i'm not gonna stay on the bus to have him play the bid of something because i didn't read. i couldn't help us to somebody up there and you're gonna let me buy all a g as an important area of research for this 1st bound, myers expedition and algae could play a key role here to the main line of investigation with office headquarters. engineering. of course everything when it comes to of the protocol for the searching for live on so long, i didn't new teams. and how come, why wouldn't be somebody that we need to research a piece in a ton of ours? you know, so everything that i've been to and i even think nice and your team could lucy on

a food unity cell. all that stuff is more thing place to put on the german researchers can hardly wait to find out more about the various ancient algae species they've discovered in the case. they're collecting samples back at their home laboratory impairments ends. they'll place them under the microscope for a closer look. and then uh, and then the one thing that will analyze the samples and then definitely take another look at that cheat. so we want to really say it's not just one species or 2 or 3 that we're probably many, many different organisms living together have a little microcosm, so to speak in the hospital when that's what we want to find out from under the need not to do that we're carrying out genetic analysis to determine which organisms are living together here on this form. back to parents and the new research reactor is full of life in the form of ality. now it's hoped they will

multiply and the researchers can grow various algae and the reactor unimportant step in cultivating alternatives to environmentally harmful plastic. because of the 4 types you up on this one, the crates, advantage of this out diploma stock is that it can produce by protesting. so that means if you give, it should say, given the additional carbon sources then fits dose to produce, put, to recast a time. that's the basic building block for a really great fire plastic. that's called ph. be for sure fuel plastic it's most by compatible and find degraded or combustible, is it used to sutures in medicine for example. see about is prevented from somebody to care for, need to buy them to, to our bodies would probably cope much better with organic plastic in our food than with conventional plastic. under the microscope, you can see the bio plastic that the algae forms as white dots. there's going to be

more more time on this, but what's a problem at the moment going bike level w w s. study here is the we ingest, around $100.00 micro particles of mancha plastics with each meet. oh cool plastic. that's the equivalent of 2000 pulse because we can do that or 5 grams each week. um that's the equivalents of the credit card division in minor to take. that means that on average that everyone in the world every week is each and a credit card with a plastic ireland to be cards a cluster, the eventually the laboratories research reactors will be replaced with these window modules. then everyone can watch algae at work in their own window. the macintosh, this is cooling called, so to speak. you need about some of these. these are much less voltage, just an aerosol sprite, 90 percent less voltage. laugh pennsic gas exchange, the easier to harvest and so on. that is what this is on newest model for growing side effects here in the future. in sort of 2 out of 10 not dies

could be grown here in these beside windows or cosmetics for even food. i didn't you know the cussing somebody out even in china? no. yes. as a traditional new yes dish. for instance. worse, that's the most talk flag in the form of i'll give it's collected from the best we can grow it here under these conditions and then set it where it's like come be crowded in the open liquid process on each box and then it will take some time before the 1st products made and parents ends come onto the market. we still have a few years to wait to for the 1st organic concrete produced with spanish cave algae use of drugs. it says this block is now 1st prototype. i'm about to, to you. we introduce to cyan and bacteria strain into the concrete in process of it's not yet one from the cave. the. this is a bar treat strain energy about how we carry down south those preliminary tests with a test to see whether this process works with cyan or back to your, your

a tool and in the loan to we want to work with the cyan, a bacteria from the case since they calcified naturally, we can then use the process for concrete productions in this way. the system will be another 2 to 4 years before we've optimized the system of the just too soon to tell. yes, we're on the right track. in our fat in the eiffel region, a metal construction company is building for large bio reactors. the window modules will be 2 meters 40 high one meter 42 across. now the question is, which one goes to the boss and then which at the top of this one here. and that there is one of the research or michelle lack of chose to seeing the modules for the 1st time today. because audio, bennett is tight. amazing. we need to really think, okay, that should defend roughly key,

but then you see how big it is in reality and the dimensions that i mentioned that we've never had before. and that's also really important. those look, we're always working on the bar to scale. use 100 milliliters by maybe 10 meters is the largest size, but seen our 100 leads to prove us a whole lot of a story that we're really getting into it now on the ground. this guy, i don't think me personally going, it's going in close. and steve the, the state of rhineland to pull out native, picking up the bill around $80000.00 euros to produce 4 modules. the reactors can be set up in a laboratory. however, the researchers can also hang them on building facades and grow algae there. there's nothing can put them right on. the water comes in from the top, just just makes sense and then spreads through the holding scenery on the when it drips down it's fed. how's it going to the bottom and circulates back to the top, down whole slide to see if we get them for the small metal and steel construction

company. it was quite an order, not least because they had to procure acid resistance, stainless steel. but when i read the cool for tend isn't so bio reactive it 1st i wanted what it was. so is it something it's all make? that's what it sounds like. it 1st go in retrospect. so it makes it a lot of similar, some goals. i must say i find what they doing. they have very interesting discuss it. i'm a fan of the project, something for you. i'm gonna find it to prevent the algae in the module from getting too much light for dying from overheating. sun protection is built in the fact that it never the sucking so high inside of the react and mustn't get too hard good. because otherwise the l you would get to halt as well. and di, um yeah, that's why we've changed it from the sun 1st from above. and then again from the site the event will hang cold by the recounts. and the codes that will surprise to a provide even more shade for the result is this. under course of this type of assessment for them to act on the lp and the reactors will soon be producing file

plastic and absorbing c o. 2 from the air. they'll be hung on an actual facade and stood guard for research purposes. michelle lack of toes is convinced l. g reactors like this, have a great future ahead of them and will one day be part of every city escape. this is this moment tom view like photo more tight and then the way we have photos of all tags. where in the 1970s we've developed it. so just making a new craft quickly, we can actually get them to use those on the houses in the house because ultimately that's up to the politicians originally intended us to put it. if they subsidize, it doesn't feel good will happen very quickly without the size of the world of cost . well, certainly part of the mix forced time from feeling good for now the l. g researchers from parents and still have a lot of exploring to do in every corner of the planet the

of the week. join us on our search for the onset to almost everything. it's going to get very interesting because we're going to a micro to track down elementary policy and asking, how do they hold the in 15 minutes on the w. and so the conflicts own with tim sebastian presidential election is in russia of the usual full gun conclusion with nothing

left to chop, not even the best in jail of the leading opposition figure. i'll explain about me, my guess is the russian come and take the andre collect the recall the economy. he rushing your agent center in moscow was nevada. is such a serious? correct? you have to be to conflict in 19 minutes on d. w, the, these places in europe stepped into a bold adventure the treasure map for martin globetrotters. describe it as some of us wriggled, begging sites on youtube. and also the only way i can be on top is to create my own empire, discover stories that

just to take away the journey, the destination, right? size, house based, document, trees a side note, tempting entry, cost about why does that mean? i think it's like, now i'm leave them on the new host. join us for an exciting exploration of everything in between. this is a video and audio production 5 d w. i hope video with unit the

is a dw dues line from berlin is time running out for tick tock in the united states. us house of representatives has approved a bill that could band tick tock. if the social media platform refuses to sever all ties with the chinese government, also coming up a close ally of the late russian opposition leader election of all ne, attacked with a hammer in lithuania and he's pointing the finger at vladimir putin the .
