education makes the world make up your own mind. made full minds. viruses and bacteria can make us sick. so we do everything we can to fight them off . but some like codes are actually useful. the intestinal bacteria of a pregnant woman isn't just important for her health. what she consumes also directly impacts her baby's immune system. and some viruses are useful to. they can even help extract valuable raw materials from electrical waste. welcome to tomorrow. today dw science program, the we humans driving more and more animals from the habitats,
8:31 pm
increasing the risk of exposure to diseases. that's what's happening in the prison in rain forest, near the city of malice were such as back around the hunt that potentially dangerous fire sides the sometimes it could be more stable very. i think it's your vehicle. adam handy of his team hang tramps and the amazon rain forest there on a mosquito hunt. that's because these mosquitoes could carry a new virus that could trigger them next. pandemic if so, with the virus hunters find it in time. there the 1st ones who could detect it, and these collections require lots of successive or in the rain far as kind of you said to be home to the particularly dangerous mosquito. those administrative team
8:32 pm
are targeting them and have any falling into the trap. no must keep the virus hunters are not only after mosquitoes. they also want to catch monkeys. the number of viruses and the animal kingdom is astronomical. we'll never find all of them. that's why it's so important to monitor the danger spots where humans and animals collide. like in the amazon rain forest, a key. we my 1000 things in my now monkeys. mount people directly has pretty much the squarespace, so they actually live in the jungle. but they come to farms or need fruits and food instead, people store it as all the dice sending messages. there's a constant exchange commute. it's always decent. most i think did i fill my mouse with its 2200000 inhabitants? is the capital of the state as own us. the police has a so called hotspots here and people in wild animals collide and the risk of
8:33 pm
a new virus jumping over increases because humans are penetrating deeper and deeper into these viruses. research are marcelo gordo wants to capture monkeys. the animals are increasingly coming into contact with people because they are losing their habitat. they are forced to search for food near humans. marcelo hopes that to colored cameron's will fall into the trap. these kind of a tricky day are highly endangered, living only around my house, the to can transmit diseases to humans, but can also be infected themselves by humans with yellow fever or corona viruses, for example. that way viruses can survive and keep on mutating pretty much as my wide is thing was. there's another complicating factor with great, which is that they are often hunted in rural areas 5 the but i only meant that so don't with the i'd be doing this habit of hunt in wild animals handling the dead
8:34 pm
animal. contact with blood and vis or for example, is also another source of infection and transmission of disease, a 4 digit code dodge. and he said, as long as you do and this is not going to change any time soon. many low income families in rural areas rely on eating wild animal meat. and that's how dangerous viruses can jump to humans. marcello gordo and this team, therefore regularly take blood samples from the animals and detached them for viruses and pathogens. then they released them again. much more difficult to monitor arms, egos, adam, hindi, and his team are on the trail of mosquitoes. mosquitoes primarily transmits so called arbel viruses such as west nile or dang, gate. these viruses replicate invertebrates and are transmitted by blood sucking
8:35 pm
insects through bytes. another research station is located in the heart of a 10000 hector relatively intact forest reserve. the question is to mosquitoes deep in the forest carry different viruses than those on the outskirts finding out is difficult. this is the beginning. they were really difficult for us to catch this now as in a lot of words i'm with them. and so we spend lots of time in the fields. i'm trying to understand wherever we can catch them, how they behave. um, and we've suffered a lot with the way so where do they live the really dangerous mosquitoes at the very top of the trees, adam suspects of a species that are threatening to humans. to prove it, the mosquito research or a set up a 10 meter high research platform in the middle of the forest backs. and it is
8:36 pm
mostly, it's a, it's going to be quite dangerous for people because these on things that we normally come into contact with. so they're likely to expose humans to pathogens. the immune system is not used to the mosquito species that leaving the rain far as kind of like it hot and dry down on the forest floor with other species that like it shade here in cooler. but when do the dangerous mosquitoes come down from the tree top? to find out adam and his team catch mosquitoes in different places, different types so. so when we see a so far as staged, whether it's the 3 of the fire station to build housing, puts a timber or to create 2 roads we all to the conditions of the might to climate. so as far as the edge which has probably had previously been needs to far as kind of be again becomes houghton dry. and these a conditions that these kind of p dwelling mosquitoes bases like when they come
8:37 pm
into contact with these hot and dry conditions, been more likely to, to send to ground level and potentially have contacts, switching surveillance and the jungle may work, but it would be easier to curb brain far as deforestation. after all dangerous mosquito could be lurking along every new road. our bodies are constantly confronted with new viruses and bacteria. how does our immune system learn to recognize new pathogens? and how can it tell the difference between dangerous and datas and microbes that a harmless or even helpful the immune system. we know it as our defense system, but it has another much bigger job. and that is to keep us and our micro bill inmates in balance. how exactly the immune system does. this is highly complicated
8:38 pm
and not yet fully understood. one thing is certain, it must react without over reacting. so it shouldn't just attack enemies. it must also leave friends alone. for example, microbes that help with digestion produce vital substances or displace pathogens. but how does the immune system know which microbes are the good guys and who the bad guys are? as with every system in the body, the immune system also has controls that fire it up or slow it down, or our microbial inmates help with this fine tuning microbes convince or removing system to let them stay the syllabus even though it recognizes them as invaders. this is exactly what makes our immune system
8:39 pm
top notch. it can react quickly to threats. and at the same time, it slowed down so that it doesn't lash out wildly. mean each is crucial because the diets influence which mike krebs collection means has times of the new born child. the micro biome is the foundation of a healthy immune system. birth is the 1st contact with the world, the bacteria. in the birth canal, the baby directly encounters and absorbs the mother's intestinal bacteria for the 1st time. these bacteria form of 1st protective shield in life and the even help the baby build its own immune system. then get off the bed when we come into the world, our immune system is not yet fully formed. it has to learn during life to recognize pathogens that is viruses and bacteria and to fight them off the intestinal micro
8:40 pm
biome. so please the name on the role in this build up process and leads us to be efficient. recognizing and slicing of pathogenic relate to own molecular physicians . stephanie can research as the influence of got bacteria on the child's immune system, that insults guitar. in a high profile study, she was able to prove that it's crucial what mothers eat during their pregnancy. ready this is because the mother's intestinal bacteria are already influencing the child to be the. the research was able to show that messenger substances from maternal in test still bacteria are transferred to the child via the placenta and thus influenced the development of the immune system. ready ready i'm with the symbols you have to be consciously, definitely victim enrich, balance, buried, and think about whether or not reading the to that child close to that kenzie or
8:41 pm
whether you can do with bounce. it continues before and maybe think a little more often about what you reach and when and, and what quantities invasion making if nutrition is also crucial for a healthy, a mean system in young children. that's why stephanie can wants to conduct another study to see how a child's micro biome develops in the 1st few years of life. unless we did one with us study, we want to find out how the child's micro biome develops also. but especially in the 1st 2 years of life and of particular interest to us is what's influence breast mount plays have. and whether that can have a long term impact on the child's health and susceptibility to certain diseases costume pick on kind of having kind of the mother is pump some breasts. no 1st step in the gun on a swab on the arm gives information about the bacteria on the skin,
8:42 pm
but the bacteria in this do are decisive. she takes these from a freshly filled diaper. the feces are particularly interesting for her because here she finds the intestinal bacteria that make up the micro biome, the anal pumpkin to the nutrition of the child. and the 1st use of life is particularly important. because we know that nutrition has a great influence on the intestinal flora, it's like alpha. we also know that the intestinal flora is formed in the 1st 2 to 3 years when the micro biome can still be control and changed. this can have long term effects on the micro biome composition on the health of the child, and later in life, that's just not possible as i'm living, it's the same god dismissal. no. lucas, for her. it's clear. breastmilk is certainly the best nutrition in the 1st few months, but mothers who can breast feed should also benefit from her research lab for us to go home. once i know that for the longest time, we hope to understand which bacteria
8:43 pm
a useful early in life and whether we could give them to them. you're the ones who own getting breast milk as a pro, bio sick covey or took a god on and whatnot. and also imagine that both will feed in will become even more sophisticated unable. no, i was good. i asked of it. she's at the very beginning of her study. she wants to understand the world of bacteria even better in order to be able to use it for better health. for all children. 39, truly in my kirby, all cells including bacteria, viruses, and funky live own and in the opportunities. the gal that is the main notation of the human micro biome, put on micro biome, is not this diverse as it could be. why is that? and is it also true of animals? a group of pigs and a pile of pig done. these 2 women are interested in both the veterinarian here at
8:44 pm
the ash about the animal. a park is happy about healthy animals, and the molecular biologist is interested in their faces. they've taken almost 400 stool samples from 38 different animals from susan parks to investigate which and how many micro organisms are in them. what about soon as of one reason for my motivation is because micro organisms are. so under estimated time, people always talk about germs negatively. but actually 99.999 percent of the micro organisms that surround us are good for us. we live in cindy osis with them. the whole human system wouldn't function without micro organisms. and that's really the combined genetic material of all micro organisms in a particular environment is called the micro biome. to research the micro biome, they looked at primates, carnivores, and even toad and on toad on units on the span,
8:45 pm
ruminants are especially interesting because we know they have a very diverse micro biome due to the fact that the justin takes place twice out. it's very effective from the energy yield. it's a bit like a bio gas plant. so the course stuff comes in at the top and then it's broken down one step at a time. and that's about in order to be able to digest hay and grass cows have millions of different bacteria in their room. and in their research lab at q university, scientists dissolve stool samples until they have the smallest parts of the cells. what remains is the dna, or they've also studied samples from humans, which show that our micro organisms are not very diverse. he for she can add to god and the more diverse, the micro organisms in ad on our body, the better the balance of our immune system. and we suspect that reduced microbial diversity is also associated with the human system. deficiencies which can lead to
8:46 pm
the development of chronic inflammatory diseases, central and 5 starter. for example, crohn's disease or multiple sclerosis. their study also shows that the micro biomes of people from some african countries are much more diverse. this is because they eat differently off and live in large groups and have close contact to their farm. animals, causing a bung says that we too should visit farms more often. but above all, move away from industrial sugar and eat a more plant based diet. just like them fun like bacteria and micro organisms. viruses are not living organisms. they require a host in order to survive. there are also viruses that infect and replicate only in bacterial cells. these so called
8:47 pm
bacteria of stages often used for food production medicine, gene technologies. and they can even help extract rule materials from electrical waste without the need for toxic chemicals to date, it's been almost impossible to efficiently recycle electrical devices by separating them into more than 50 different substances. one by one. this unlikely environmental thread is making life difficult for recycling companies. even though the energy saving light bulbs used to be a beacon of hope for german energy policy. the light bulbs themselves are full of poison. on the one hand, they contain highly toxic mercury. but there's also a mix of non toxic valuable powders made up of rear earth and other substances. when mixed together, they produce the white light but separating those
8:48 pm
valuable substances from mercury and from each other is so complex that energy saving lamps usually don't get recycled at all. that's not moves. a lot of powder is stored separately as hazardous waste underground and contained in these energy saving lamps contained luxury, which is toxic, and we don't want to, it's in our household. this is the bitter reality of recycling a waste. up until now, thanks to 5 books, handbooks, institute for resource technology. they want to show the recycling industry that they're making the impossible possible. the plan on extracting the railroads from energy saving lightbulbs. to do so, they use a surprising tool. the bacterial range m. 13 bacterial features are viruses that don't infect humans, animals more plants,
8:49 pm
they only effect bacteria. the researchers now hope that these pages and identify and isolate where it says well the bacterial phage and 3rd gene has a special property. it has results made of protein on its surface. the researchers now want to use these bristles as so called bio angles. if the virus is genetically modified, it develops a wide variety of these bio angles, billions of different ones in science. this collection of m 13 variants or mutations, is called of fiji library. each individual variant has its own highly specific quote to fish out the rare hurts in the energy saving light bulbs the for what they call selection in the test tube. the researchers 1st find out which em 13 variant might be interested in where are they
8:50 pm
therefore mix one of the river. it's to be recycled with a complete and 13 page library. busy vm 13 mutants that happens to have the right surface protein gets stuck onto the rare earth in the test tube experiment. the phage and the rare earth part then separated from the rest of the m. 13 variants in the centrifuge or the rest of the page library is scratch the. the 2nd step determines which m. 13 variant is involved. the corresponding angle brussel for the pure a surface protein, not the virus can then be ordered in large quantities. in step 3, this surface protein is attached to a tiny back that's important for later use on a large scale by the recycling industry. in this process that
8:51 pm
feeds proteins binding to microscopic federal magnetic fields. the result, magnetic fields covered with spines of m. 13 bio angles resembling a chest. the green light is the m 13 vile angles attached to the bead, ready to pounce on a very specific river earth. but how did the helm votes researchers come up with such a novel idea? the original idea actually came from the american george pearson smith in 1985, he recognized the potential of the odd m, 13 pretzels, and meet the 1st limitation attempt, so that he could use the bristol, by the way, it goes as evidence of very specific substances like anti bodies or other proteins, piece suggested randomly producing a wide variety of virus mutations. george pearson smith idea, tramped in laboratories around the world. there are now billions of variance of m,
8:52 pm
13 the bristles of which have been randomly altered the so called sage library mentioned earlier, smith is over to the $1.00 to 2018 nobel prize and chemistry for his idea. and then we did seen on this page display is used in medicine engine, pharmacological application that's very rarely one works with metal, with an organic substances, but a gram of lemon. how that contains $190.00 milligrams of rad us. there is no richer results. the red us and these energy saving lamps be spent on ken smith side you work with a rare earth contained in an energy saving light bulb. that questions being put to the test here. this vessel contains a mixture of luminous powder, from energy saving light bulbs and neon tubes. now the magnetized m. 13 bio angles are simply added and stirred briefly. then another magnet goes into action. as this
8:53 pm
also comment in the recycling industry on a large scale when the mixture of bio angles and rear roots has passed through this magnet, the end 13 by a windows, which if the experiment has worked, should have combined with the desired rivers by now and be stuck to the magnet if the magnet is turned off, the magnetized pile angles and rear ers should be able to detach from them. good, and be transferred to a new container. what's, what can i do that piece by piece for each element, and then i'll have separation of everything by type at least in theory. the quick test with the laser shows whether it also works in practice. if the process was successful, the suspension should now blow green instead of white. and indeed, the round earth is now present in almost your form. if it works with energy saving
8:54 pm
light bulbs, it should at least in principle, apply to other items like cell phones to other things that hasn't been any research results yet on how to successfully separate all 60 elements from a smartphone engine reinstalled them in a new one. that's why we should be interested in making bessie use of on domestic resources, and that's a waste because a waste contains real treasures that are waiting to be under the pepsi. and so these sweets addition, if tomorrow today dw science programs, thanks for watching and see you next time the
