most people learn to classify small handful of animals, edible, and all the rest they classify as disgusting. w series about our complex relationship with animals. the great debate. what's, you know on youtube, dw documentary, 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 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 12 for over a year. we've accompanied researchers from kaiser's low tones, 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 out these channels can take in waste materials and waste water and an extract nutrients from mann's office. we've already live 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

in england 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 what 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 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 and effects henry, aware aware of the big catch? incredible things, i've never seen anything like that. it's quite incredible loss to what we fidget closet, 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 quite a 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. the we're also seeing to what extent they've adapted to the light and how they utilize the unofficial part. it says

the for the allergy researchers, this can to bran cave is a godsend. the only person might just the a mazda you looking rock face, but for the biologist, it's a window into a fascinating world. an extraordinary multi generational colony. fidget isn't having. you can see these colorful surface here. these fluffy little gray green pads doesn't get these assigned a bacteria. and so with these yellow ones here, these pink jelly light clogged. so striking the optic, that's the particular sy entered bacteria and we're off the globe back to clear. we'll talk each one of the oldest living, so i entered bacteria and so it's a very basic primitive cyan and bacterium that's leaving here alongside more modern spacing is a bit of, of all the different li, gimme their own living here in the colon, including this is like the misha locker towson

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 these days 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 kinds of if we found different species. so certain processes a difference here in the are either so the allergy here is quite tough, 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 enough in the town. and there's only a 100000 the line 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. and for 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 and campbell 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 of materials. so it is not just the biological aspect which is already fascinating it and that's, but it's also the practical application of something, you know, lovely. got you and, but i think in that regard, patrick and michael's ideas are in line with us a, as in mike and other words,

if you think we're happy to continue supporting them here. and we're looking forward to working even more closely with the bill. you're gonna have to build on most, but it's not it. is that a push it till 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 escaping time to take on those today that and if you had just a few minutes aligns perfectly with the original plan to draw on the potentially lease unexplored micro organisms or gap them all apparently capable of producing substances that have not yet been recess. antibiotics, for instance, at the moment. so these organizations that are in fish competition with each other . so they put to you santibanez things sort of, i need most of it didn't know, not incompetent yet. and today you was interested in it on and see if you think like produce new tooth as a service, food for other organisms. so like

a set of this food for us digital simply deal could all be possible. but english what, but understand, he meant that the 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 this year, or the i'm, for example here, your advice selected cox at the ups is from the i'm talk 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 complaint, the new algo we've identified, even from sol involved and the optical stuff, all can attend the, to the candy. what does that do? the, the kind of you have to do it has a smaller 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 that by the kinds of iceberg companies, 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 of the amendment as a can be crossed. and um yeah, 2 bucks. that's a man of all the samples we collected are in here. do you think of some of them the german researchers are traveling the world on the hunt for new species of algae. they most recently spend 4 weeks in the out of comma desert and she'll a while the whole spine of the cactus here, the of the trend to police 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 that i can also withstand very high temperatures in biotech, the logical reactors, for example, on somebody 0 temper to an old phone. that's number one, number 2 and extreme habitats like back to organs. you always find organisms that can do something very special stuff, such as producing special active substances except for adopting specific new metabolic pathways. stuff like the big armstrong some allergy enter into symbiosis with fund guy in order to survive and extreme places forming legans. patrick young . the found such l, g, fungus, symbiosis, in the, out of comma, the fun, this becomes a kind of sun shade for the algae does, is when the and the, among other things, it also provides you the protection against the hush radiation one finds in the,

to comment is it is the lp and not mo bile they trumped 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 con kabbage. they produce a certain pigments in the case of the species, 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. 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 method research as being funded by the german federal state of rhineland, polite, nate, they see it as an investment in the future and on the gift stuff on that. and those kind of hit us on, on the state level, many companies would benefit from becoming a little less dependent on energy supply as a product. 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 kind of 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, his shots unknown to get caught out with carly, enjoying an initial spark of interest move just hoping to progress as far as possible with the companies i need, ultimately implementing some of the only thing is we've been we're searching for yeah, so on this one,

got it under forced tom. yeah. mine's of. yes. wonderful. just great. does the 2 researchers are unpacking a new piece of equipment. a photo bio reactor that says it will allow them to grow algae that normally live on land in liquid and thereby control the way they reproduce. of the documents on the side of the problem as well. documents, i think ro, an a controlled amount of stuff. i don't know large scale this isn't 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. in 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 this. but the of the month, 2 of us. what you see here, for example, of the terrestrial out, can you provide those internal stuff in school?

the multi cellular and thread like this, as a med syndic to is feed them into. you can see immediate, they tend to clump together on 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 them vix this. so i'm on to kind of follow that you haven't tried yet. yeah. that was a comp. so was it will take a doing here. we don't even know yet. we're curious stuff isn't much fun. you want us to inspire that. you know, the reactor is an important intermediate step towards producing larger quantities of bio plastics for climate friendly summit one day exist. so this isn't close that window seat upstairs is a big difference between trying to fools nature into the lab. that's to say, conducting experiments on a small laboratory scale thing and being able to think on a larger industrial scale and couldn't, that's a whole lot of botox movies. any of this thing done,

if not tons of the set that took the longest movies connection, it's 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. lots of the marble 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 office the for the whole we to all of a star cells food order. and as i said, 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 to send a deep into the cave and reached tomorrow's 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 about 10 not to go outside stuff up. so that's, that's a side effect 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 2 weeks hail to feed, creating oxygen and food at the same time, by on no, no meant to products in other, out a probably 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 say of abuse because i'd be willing to take a look on the, on the i know tech by selling products. okay. the young thing would be actually to be a mass not taking advantage. now we're not the mass. why don't we come made mistakes? diana and i can stay on the bus to have him play the bid of some, but it, because i didn't read that to help us to somebody up there. i'm going to let me buy all a g as an important area of research for this 1st bound. mars expedition and algae could play a key role here to the main line shopping for station we offer psychology, engineering, of course, biology everything. when it comes to of the protocol for the searching for live on so long, i didn't new teams and how come we want to be so 5,

and we need to research the piece end of the toner morris. you know, so everything that i've been to and so if i went techniques and your team cuz you on a food unity cell, all that stuff is more think tasty, pronounced. 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 then uh and then the one thing, then we'll 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 managers in 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 a parent ms. hence,

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 the 4 types you up on this one of the crates advantage of this out to put on a stock is that it can produce by testing. so that means if you give it sugar. so you should think, given the additional carbon sources from fixed cost to produce, put, to recast, right, and that's the basic building block for a really great fire plastic that's called p h b for sure. because fuel plastic is most by compatible and find degraded or combustible, is it used to suit chosen medicine for example, see about it's prevented from somebody to, to need to buy them to, to our bodies would probably cope much better with organic plastic in our food than with conventional plastic and under the microscope,

you can see the bio plastic that the algae forms as white dots. because there's going to be more more time on this. but what's a problem of the moment going bike level w w. s. study here is the we ingest, around $100.00 micro particles of mancha plastics with each meal, plastic. oh, 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 to take that means the toner of rich that everyone in the world every week is eating a credit card with a plastic. i like to be cards a cluster eventually the laboratories research reactors will be replaced with these window modules. then every one can watch algae at work in their own window. the americans 1st, this is cooling called so to speaking of us, some of these even much less voltage, just an aerosol sprite, 90 percent less of all times. they have pets, a gas exchange, the easier to harvest. and so that is 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, and these beside windows or cosmetics or even food. 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 where it's like comp being crowded in the of a 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 of trucks. this block is now 1st prototype. i'm about to, to you. we introduced this. i entered bacteria strain into the concrete in process of it's not yet one from the cave. the. 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 tool in the loan to 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 the system the door. too soon to tell us we're on the right track. in our fight in the eiffel region, a middle 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 with the both and then which at the top of this one here and that there is with the algae research here. michelle, alaska chose the seeing the modules for the 1st time today because audio,

bennett is tight. amazing. 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 a larger scale. use 100 milliliters by maybe, and this is the largest size, but see in our 100 liters, it seems that it's a whole lot 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 state of 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 on. the water comes in from the top. it just has made sense and then spread through the whole entire area and the when it drips down it's fed out into the bottom and circulates back to the top of the down whole slide to

see if we get them to be their normal 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 to attend isn't 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 of sense to me going. i must say, i find what they doing. they have very interesting discuss. i'm a fan of the projects, something for you. i'm gonna find that 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 disruption so high inside of the react to muscle. to hawes is good because otherwise the out you would get to halt as well and die. 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 sprang toward provide even more shade for the result. is this,

under course the 1st type of especially for them to act on. the algae 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 and should guard for research purposes. me say a lack of toast 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 were in the 1970s. we've developed it so it just being a new crop quickly. we can actually get into use of i'm on 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 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

the fast, faster, faster quantum computers. it takes them seconds to calculate what used to take here . but how does it work? and why could quantum computers replace animal test? let's explore the wonders world of quantum computing. in 13 minutes, d, w, equal africa,

carbon offsetting projects are sprouting up all over 10 young ladies after that is the people attending a predictor and i'm going to the single unless something pulled around to see exactly what can these efforts really make a difference in 19 minutes on d w, the one is main kinds, oldest ambitions could be within reach. what is it really is possible to reverse the researchers and scientists all over the world for in a race against time?

they are peers and rivals with one daring goals to help smart nature. the more likes watching it on youtube, dw documentary floating away when it's 40 degrees celsius and the shade can be only during times of climate change. i asked wherever, what was the most difficult part of their job. uniformly, they spoke about she's being most difficult part of their jobs. men described it as a feeling of drowning feats. sky was melting, and you couldn't read. how do rising temperatures change from different parts of the world? in february, march 15th on dw, the,

this is vito, the news live from berlin. a critical moment, so hazy us secretary of state and me blinking meets with kind of being leaders to plan an intervention in the gang ravaged nation on groups continued to attack government buildings and demand the prime ministers. ouster, also on the program a ship carrying $200.00 tons of food for gas out weights to leave cyprus, the open arms will use a new maritime paid card. or what do you say they'll problems over unloading and distributing supplies?

and the swedish flag is raised at nato headquarters to markets.
