green one german research team is convinced that algae 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 very 5 percent of globe black as far as c o 2, come some construction to the from 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 tones, university of applied sciences to the depths of a spanish case where life on mars is 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 get those can take in waste materials and wasteful to then extract nutrients from mann's office. we've heard this line 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. okay? 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 these researchers led by biologist, me, see a 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 a weight and there are almost 300 caves in this valley alone and some 4000 in all

of count abriya. one case in particular is of special interest to the german expedition team. the what they discover here is mind blowing me sure. yeah. lack of toast. finds organisms that bear witness to the very origins of life on earth, the god of him. how much do you have just found a huge patch with one of the oldest sonya in the back scenario? where aware of the big catch incredible things i've never seen anything like and so it's quite incredible. last to what we finish clock is that right? what's left him speechless 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 the isolating. you sign

a bacteria and use them for biotechnology classifications. 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 can debris and cave is a godsend. the only person might just see a mazda you're looking rock face. but for the biologist, it's a window into a fascinating world, an extraordinary multi generational colony. since it isn't charming, you can see these colorful surface here. these fluffy little gray green pads doesn't get these as i enter that curio. so with these yellow ones here,

these pink jelly light flowed. so striking the optic, that's the particular sy entered bacteria and we're off the flow. we go back to clear, we'll talk each one of the oldest leading cyan or bacteria and back to so it's a very basic primitive cyan and bacterium that's leaving here along side more modern spacing is a bit of a voltage differently. they're all living here in the college and career. this is like the misha lack of toasts and patrick young are thrilled with the wealth of research material they found and excited about the new questions that arise from it to the best we know that they can survive without much lice 5, but we don't know exactly what the lower limit t's is also the question of how exactly these 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 800000. the line from above can reach something as a volume for losses in the dog by simply structure that physiology about that photo synthesis. and so they can use nothing. i mean the visible light spectrum, it much less than this. we switched the exciting of this and they may also be able to draw from further along the range of light in that, in 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 with us, not just the biological aspect, which is already fascinating it and that's, but it's also the practical application of something. so you know, that really got to him, but i think in that regard indeed of patrick and michael's ideas are in line with us and like, 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 program, but instead of the gate, push it the 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 and come up if it's time to take one knows 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 resent on the c panel takes rings than just a moment. so these organizations are in 5th competition with each other. so they put to you santibanez things sort of these, most of it didn't know, not incompetent yet. and today you was interested in it on a tv, i think like produce new tooth as a service of food for other organisms. so they could serve as food for special typically deal could all be possible, but in google, but i must tell you meant that the on both of the set 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 worlds 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 and large piece yours to i'm for example, here, you know, if i selected for cops at the oaks extra me, i'm talking to the units cellular. how guys here we've isolated micro claudia for it like how go from very hot that's a region. so when i complete the new algo, we've identified even from sol involved in the arctic on the all can attend the, to the candy. what does that do? the, the kind of you have to do it has a small red. and a quite unusual with 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 by the comes from vice big companies. there were some of that kind of caught up in ice for example, cold. how they behave like rebuilding carl and producing a sort of troy piece. kenneth, here is one of our new projects here is to see whether we can use this as

a submitted substitution as a this amendment as a can be crossed. and um yeah, 2 bucks. that's a man of all the samples we collected during here. do you think of something that tom determined 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 of the cactus into the tier of the, of the trend to polio samples. that's a special type of liking that grows on the tips of the tax id number is next period . assets are extreme locations. it's very hard and this little volta venue of the organisms can survive. the 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, in extreme habitats like that to organise you always find organisms that can do something very special from such as producing special active substances except for adopting specific 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. the found such algae, 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 lp and not mo bile. they trapped in a stationary position and somehow have to protect themselves from the sun's rays, which they can't avoid with a like and like this ones that task falls to the funds will ton steps they produce a certain pigments in the case of the species, those pigments that greenish 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. how much we turn

organic waste into plastic funding? 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 facades, 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 to pull out nate, they see it as an investment in the future. going good stuff on 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 class and it's about

france. i was kind of trying 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 sense 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 tom. yeah. minds of yes. wonderful. just right. those 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 and liquid and thereby control the way they reproduce. a lazy thing. nothing is funny is i don't grow as well. documents, i think growing a controlled man and stuff. i don't know log scale, this is that we can then control that grows here, and it kind of pre culture and transfer them into loan to react to the up to one

instance. soon. an algae that's popular with biologists will be growing in this reactor. as of some buyers for you. so these, for example, is the elaborate, difficult to buy a technologist working without doing anything. with 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, of the terrestrial out. can you provide those internal stuff and score the multi cellular and spread like the size of the med send it to 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, 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 the comp time is it will take a doing 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 on that's to say, conducting experiments on a small laboratory 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 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 in 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 and future. we could also cover the east and west results 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, as 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 algy 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 or upsets or to sign it back here you can say can

waste materials and waste water and extract the nutrients from having a very different lights like we have a um they then compare to you so i'll just put it in as i can, the volume of the c o to 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, i don't know 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 o boss sony products. okay. the young thing would be actually to be a mass not taking advantage that we have 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 for 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, biology everything. when it comes to of the protocol for the searching for lying on so long. i didn't new teams. and how come, why wouldn't be somebody that we need to research the 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 see 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 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 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 in the reactor. unimportant step in cultivating alternatives to environmentally harmful plastic. because of the 4 types you up on this one of 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, but 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 prevented from somebody to, to, to need to buy them and see. 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 to send this to it's a problem at the moment that's 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 to the 2000 pulse because we can go back or 5 grams each week. um that's the equivalents of the credit card division in minor. typically that means that on average that everyone in the world every week is each and a credit card with a plastic. i need 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, the much less voltage, just an aerosol sprite, 90 percent less voltage. laugh pennsic gas exchange, the easier to harvest and so on. the surfaces, 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 or even food. i didn't, you know, the 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

be crowded in the open liquid process on each box and 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 of trucks. this block is now 1st prototype. i'm about to, to you. 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. the test to see whether this process works with cyan or bacteria, or a tool in the loan to and we want to work with the cyan and bacteria from the cave . 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. a. 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 questions which one goes at the bottom in which at the top of this one here, and that this is where the algy research or michelle, alaska chose the seeing the modules for the 1st time today because i do, i remember this type, amazing key to we need to really think, okay, that should defend roughly key, but then you see how big it is in reality and to do minutes, as i mentioned that we've never had before. and that's also really important. those are for who is working on a bar to scale news. 100 milliliters by maybe 10 meters is the largest size, but see in our 100 leads to prove us a whole of a story that we're really getting into it now on the ground. this guy, i don't think, let me push the going. it's going in close and steve, the, the state of rhineland collab, nate is picking up the bill around $80000.00 bureaus to produce 4 modules. 3 actors

can be set up in a laboratory. however, the researchers can also hang them on building facades and grow l g. there is nothing can put them right. as far as the water comes in from the top, just just makes sense and then spreads through the holding scenery on the when it trips down it's fed outlook and at the bottom. then 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 10 does and so bio reactive at 1st i wanted what it was. so is it something atomic? that's what it sounds like. it 1st go in retrospect. so it makes a lot similes, some goals, i must say, i find what they doing. they have very interesting discuss. 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 stuff inside of the react to mustn't get too hot. good. because otherwise the out you would get to halt as well and die. 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 costs that will sprout and toward provide even more shade for the result. is this, under course the 1st type of especially for them to act on the lp and the reactors will soon be producing bio plastic and absorbing c o. 2 from the air. they'll be hung on an actual facade in stuttgart for research purposes. me say a lack of toast is convinced elegy 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 were in the 1970s. we've developed it so just being a new crowd quickly,

we can actually get them to use those on the houses in houses. 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 for now the l. g. researchers from farmers and still have a lot of exploring to do in every corner of the planet. the

healthy on the coast of the researchers from switzerland, one to find out with us official intelligence, they scanned the carl reese of the coast and processed the data invalid. the results. a 3 d model training tomorrow today is next on d, w, the

this shadows, these are costs and video shed light on the dog is devastating. colonial har is infected by germany across and he employed to score suppose tactic farms and destroyed lights. what is the legacy of this wide spread race as depression today? history? we need to talk about here, the stories, shadows of german colonialism. several good, 3 misdemeanors. rice, regression must be in coffee rate and burned in south africa. people with disabilities more likely to release the job of the lack lives matter, protest shine a spotlight on racially motivated police by the same sex marriage has been legalized discrimination.

we all because life is diversity. definitely made the around the world horribly start dying. mass bleaching events are growing ever more common driven by a record breaking each end forming ocean. if the planet warms by 1.5 degrees celsius between 70 and 90 percent of research globally could di researchers . oh no, rushing to map and inventory, the world's remaining corals. all that and more coming up on this edition of this sewing and show on dw. welcome to tomorrow. today.

the quarterly based off the coast due to booty in east after.
