of the, the whole has a color that is 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. within the best 5 percent of globe black as far as c o 2, 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 itself for over a year. we've accompanied researchers from kaiser's low towns,

university of applied sciences to the depths of a spanish case or life on mars as being stimulated here on earth or in space. algae could be the key either can come up 1st, go for a 1st name and i'll give you all can take in waste materials and wasteful to then extract nutrients from mann's office. we've very light and that 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 probably amongst the best organisms for producing food, but i don't know the

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. binds 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 effect seen? are you aware aware of the big catch? incredible. this is, i've never seen anything like that. it's quite incredible. i'm. it's a 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, the noise on one hand, we really want to discover and isolate new sign and 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 photosynthesis 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 category in caves is

a godsend. the only person might just the most in booking rock face. but for the biologist, 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 doesn't it's visa sign of activity. and so with these yellow ones here, these pink jelly light clouds, the striking, the arctic. that's the particular sy entered back tyria and we're off the glow. we go back to us clear, we'll talk each one of the oldest leading cyan or bacteria and book to so it's a very basic primitive, cyan and bacterium that's leaving here along side more modern species. a bit of, of all the different li gimme they're all living here in the college and career. this is like the misha lack of 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 best we know that they can

survive without much lice 5, but we don't know exactly what the lower limit sees. what about 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 either. so the allergy 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. no wonder down, and there's only a $100000.00 for the light from above. can reach them as a volume. allowances in the dog is a little they simply structure that physiology about that photo synthesis and the spring so they can use nothing in 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 and the random non or in the fall, right or 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 to the he didn't have it, even gumble a, you'll get tons of a new field for such. 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 you know. lovely. got them. but i think in that regard and do the patrick and michael's ideas are in line with, i say, and mike and other words, we think we're happy to continue supporting them here. and we're looking forward to working even more closely with the phone numbers. but it's not, it, is that

a push it the here instead of you many 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 in time to pick one those today that and if you had to get them to lines perfectly with our original plan to draw on the potentially lease unexplored micro organisms like gap . them all apparently capable of producing substances that have not yet been recess . antibiotics, for instance, at the moment. so these organizations are in 5th competition with each other. so they put to you santibanez things sort of, i need most, a didn't know, not on going, but india and today using to scan it on and see if you think like produce new truth as a service food for other organisms. so like a service food for us, digital simple video could all be possible. but english what, but understand you meant that to be on video 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's the largest collection of terrestrial fiano bacteria, algae that live on the land, not in water. for study purposes, there being cultivated and liquid, none the less. over $350.00 species from all over the world can be found here. gums of march of this year or the i'm, for example here, your advice selected cox at the ups is from the i'm talk to for you to send you the how guys here. we've isolated micro call us a for it like our from very hope that's a region. so then a completely new alika we've identified, even from sol involved in the arctic on the all can attend the, to the country. what does that do? the, the kind of jobs of what has a smaller rent and a quite unusual that we don't know why it's the guy just died. 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 could somebody be covering it? there were some of that kind of caught up in ice, for example. cool how they behave like rebuilding carl. i'm kind of producing a sort of troy piece kind of times he is one of our new projects here is to see whether we can use this as a submitted substitution as a the amendment as a can be crossed. and um, yeah, 2 bucks. that's a man 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 . they most recently spent 4 weeks in the out of kama, desert, and she'll a while the whole spine of the cactus here, the other trend to polio samples. that's a special type of like in that grows on the tips of the kac side in the 1st is next period. assets are extreme locations. it's very hot. and this little volta venue of

the organisms can survive that i can also withstand very high temperatures in by technological reactors, for example, on somebody they will temper to an old phone. that's number one, number 2 and extreme habitats like that to organs. you always find organisms that can do something very special from such as producing special active substances except for adopting specific you metabolic pathways. stuff like the big armstrong. some algy enter into symbiosis with fund guy in order to survive and extreme places forming. lincoln's patrick young, found such algae, fungus, symbiosis, and the out of comma the fun, this becomes a kind of sunshade for the algae does, is on the, on the, among other things. it also provides you the protection against the hush radiation one finds in the to come and visit 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 ton demonstrate produce a certain pigments in the case of these think she's those pigments that green is yellow in appearance or 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. a beacon view. how can we turn organic waste into plastic abundance? early march 2020 to 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 algae green fuels could also be created using the same methods research as being

funded by the german federal state of rhineland, polite, nate, they see it as an investment in the future. going to just perform that and those kind of put us on, 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. pleasant as reference, 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 parents and his shots unknown to get caught up with currently enjoying an additional spark of interest move just hoping to progress as far as possible with the company's findings, ultimately incrementing some of the only thing is we've been, we're searching for yeah. so on this one, got it under forced talk. yeah. mine's of yes. wonderful was just right. does the 2

researchers are unpacking a new piece of equipment. a photo bio reactor that it will allow them to grow algae that normally live on land in liquid and thereby control the way they reproduce. a lazy thing, it's nothing. it's funny is the problem as well. is that like rolling a controlled amount of stuff? i don't know log scale, this isn't that we can then control that grows here, and it kind of pre coach us and transfer them into launch or realtors, you up to one instance. soon analogy that's popular with biologists will be growing in this reactor. as of some bars for you. so this for example, is the elaborate, difficult to buy a technologist working without getting the syndic 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, here of the terrestrial out can you provide those internal stuff in school or the multi cellular and thread like this as a med center is fill them in to you can see immediate time. they tend to clump

together when you have to prevent that with this mixing process. yeah, we're curious to see how we sound be close and then we have no experience with it yet the, the, the, the convicts. so i'm not to kind of follow that you haven't tried yet. yeah. that was a comp. so was it will take a do in here. we don't even know yet. we carry out as much fun. you want us to inspire that, you know, the, the reactor is an important intermedia of steps towards producing larger quantities of bio plastics or climate friendly summit. one day exist. so this isn't close. that window sheet ups is a big difference between trying to force nature into the lab. that's to say, conducting experiments on a small laboratory scale thing and being able to think on a launch or industrial scale and couldn't, that's a whole lot of botox movies. and his extend on us not 100 percent. that took the longest movies connection. that's for the 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 in c o 2. there are other benefits as well. some algae produce natural dies, some could end up on our plates and a lot to me on the now we have solar systems on the roof and future. we could also cover the east and west facades with these al, give reactors, i then even collect this would regularly come by to office the for the whole we to all of a star sales for food order. so say 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. i understand. 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 to send

a 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. the minds can cut 2 out of 10 not to go up 5 stuff or upsets or to sign a bacteria can say, can waste materials and waste water and extract the nutrients from having a very different lights like we have a um they've been compared to so i'll just put it in as i can, the volume, the c o 2 weeks heil to free creating oxygen and food at the same time by on. no, no, i'm going to put up some of the, i'll probably be among the best organisms for producing food in the space and can embed. now let's see what the test station in the spanish cave, the company hopes to approximate life on mars. even if some martian conditions are

impossible to reproduce, we cannot say of abuse because we need to take a look on the, on the, i know sec, pass selling products. okay. the, the young thing would be actually to be a mass by taking advantage that we have another mass. why don't we come made mistakes? diana and i can stay on the bus to have him play the bid of some of the course. and then we'd like to help us to somebody up there and you're going to want me. biology is 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 offers a quarter to engineering, of course, on biometric. everything when it comes to the protocol for the essential for live and so long as the new teens and how come we want to be somebody that we need to research a piece in a ton of ours. you know, so everything that i've been to and should have on techniques and your team cuz you

don't want a food entity. so all that stuff is mostly 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 demo and then the one thing that will analyze the samples and then definitely take another look at that cheat. so we want to really see it's not just one species or 2 or 3 that will probably many, many different organisms living together have a little microcosm, so to speak. and one of the host to come when that's what we want to find out about the need shuttle to do that when we're carrying out genetic analysis to determine which organisms are living together here on this form, back to pam is hence, the new research reactor is full of life in the form of ality. now it's hoped they

will multiply. the researchers can grow various algae and the reactor unimportant step in cultivating alternatives to environmentally harmful plastic. because of 4 times you up on this, one of the crate advantage of this out to polano stock is that it can produce biomass names. that means if you give it sugar. so you should think given additional carbon sources and fixed costs to produce material gas a time, that's the basic building block for a really crane plastic. that's called p h b for chauffeur's fuel plastic, that's most by compatible. i'm fine to grind 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 allergy forms. as white dots. there's going to

be more more time on this, but what's a problem at the moment that's going bike level w. w. s. study here is that we ingest around $100.00 micro particles of mica plastics with each meal. plastic. that's the equivalent to the 2000 pulse because a week or 5 grams each week. um that's the equivalents of the credit card division in minor cooking. that means the toner of rich that everyone in the world every week is each of a credit card with a plastic and it could be cards a cluster. eventually the laboratories research reactors will be replaced with these window modules. then everyone can watch algae at work in their own window. the markings 1st, this is cooling called so to speaking of us, some of these need much less voltage. just an aerosol sprite, 90 percent less full time. they have better gas exchange, the easier to harvest. and so that's what this is on us model for growing side effects here. we're in the future in sort of 2 out of 10 not just dies,

could be grown here in these beside windows or cosmetics or even food this and she has a cussing somebody out even in china? no. yes. as a traditional new yes dish for instance. that's the most talk flag in the form of i'll give it's collected from the test, but we can grow it here under these conditions and then sell it. whereas they come, being crowded in the open liquid process on each box, and then it will take some time before the 1st products made impairments 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 up rocks. this block is now 1st pro, so tied on about 2 t we introduced to cyan and bacteria strain into the concrete in process of it's not yet one from the cave though. this is a bar tree strain. energy about how we carry down south those preliminary tests with it test to see whether this process works with cyan or bacteria, or

a total of on, in the loan to we want to work with the cyan and bacteria from the case since they calcified naturally, we can then use the process for concrete productions in this way. the system can be another 2 to 4 years before we've optimized decision on the door. just too soon to tell. yes, if we're on the right track, the 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 bulk and then which at the top of this one here, and that there is where the algae research or michelle lack of chose to seeing the modules for the 1st time today. because audio, bennett is tight, amazing. k to we need to really think, okay, that should have been 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. does look, we're always working on the bar to scale. use 100 milliliters by maybe 10 meters is the largest size, but see in our, of 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 state of the, the state of rhineland, pull out native, picking up the bill around 80000 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 is nothing i can put them right. that's as far as the water comes in from the top just just makes sense and then spreads through the holding. terry, on the, when it trips down, it's fed out talking at 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 at 1st i wanted what it won't. so is it something it's all make? that's what it sounds like. it 1st go in retrospect, so it makes a lot of similes thing's old. i must say, i find what they doing. they have very interesting discuss it. i'm a fan of the projects within for you. i'm gonna find it to prevent the algae and the module from getting too much light for dying from overheating. sun protection is built in the fact that it never the surface, the hindsight of the react to must 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 side the event will hang cold by the recounts. and the cords that will sprout toward provide even more shane for the result. is this under course of a truck and especially 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 should guard for research purposes. michelle lack of toast is convinced algae 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. my photo more tight and then we have photos of all tags where in the 1970s we've developed it. so it just makes me look how quickly we can actually get into use of all the houses in the house is 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 decide the world of cost. well, certainly part of the mix forced time from feeling for now the l. g. researchers from parents and still have a lot of exploring to do in every corner of the planet the,

the it's time for vision rate for sustainability. but also for horsepower the, it's time for the mobo revolution. in 30 minutes on d w. this shadows, these pod costs and videos shed light on the donkey street. devastating colonial

har is infected by germany across and he employed schools to post tactic farms and destroy lights. what is the legacy of this wide spread races, depression? today, the screen. we need to talk about here, the stories, shadows of german colonialism, the drawing on innovation. there's a palace, genuine driven on which i don't expect much living with them anymore. this is not a good environment. not for me, not for my children, without civil rights. and with no prospect. but what can we do in david shadows, stats oldest, good. on the double you dream of revolution.

dictate system is uh, was full. that changed my life. the people hope for us, there is the size. i imagined we would change the world. tens of thousands of messages from all over the world wanted to help reconstruct the country. this mission became the dream. it was simply a spirit of optimism where we encouraged each other. so many things were suddenly imaginable. their idealism mess it and make it a dream of revolution. thoughts, july 20th d. w. the

. this is due to the news life from berlin. gunshots fired us with donald trump. raleigh. take a look. what happened? the former us president comes under fire and then assess the nation that time. he's injured but says he's fine. fairly re president joe biden condemns the shooting. calling it's the same. he says he'll try to reach out to trump soon. the him a welcome to the programming.
