Weekdays on dw, the. We live in a well surrounded by and take a glass of gases and want to make up the on site, must be and shielding us from the deadly vacuum of space. And these lands on teeming with life. Insects seats, poland, and bacteria. Floats in the atmosphere. Similar to the tanks on the drink with ocean currents, the tiny organisms dancing in the wind, a cold arrow plank. And for several decades, ero biology is focused on these organisms. The pizza branch of biology thats long been under appreciated. Era biology is starting to movement of life in the atmosphere, whether the tiny organisms in a cloud, the rain dropped or in the cost of a desert wind. Learning about these and born organisms is becoming increasing the relevant things to concerns about bio Diversity Health and the climate. Understanding how they influence our lives and the global animal and plant well is increasingly important. Swelling all around us is a valuable and still launch. The mysterious ecology is to be full of discoveries just waiting to be discovered. The one that i placed on the, to the one to, to receive up here. You have the feeling youre far away from everything for them to choose, but thats exactly the point we want to find out if theres life at this altitude and what type of music all of you either can when you have a book in there, circling, constructed on the wind is blowing at about 20 Kilometers Per Hour on. So a particle travel is a remarkable tony Kilometers Per Hour. Sounds like you to minutes. Lets click on see the on. Yeah, im a to at the institute of chemistry, oakland mall fell in central. France wants to learn more about micro organisms in the atmosphere. Today hes on this time its up to predict them as an altitude of almost 1500 meters to setting up time tom trunk set the observatory traps on essentially vacuum cleaners. The capture dice, select the tiny apple and travelers when p im a to looks into the skies. He knows that anything but empty the atmosphere around this is bustling with life. To escape unless 5th, the under. So now almost everything in the atmosphere comes from the earth surface. Okay, and so the mirror image of the browns best is also known as most fish, all very dynamic oxygen that is moving and makes things some a long day off today wins. Sweep over all of a surfaces staring apple types of particles. So its like less and living there and feasible to the naked eye, but it constantly around us. These particles float up to 5000 meters high and reflect the different type of tests on the ground. The the aerosols, brians about taurus, they can contain leaf dunst, poland, moans, and bacteria. The they mix together different mclinden footprints of this forest, which spreads across the whole. Over a meadow, there might be grass clippings, small insects, and minuscule traces of sheets for over a highway. A cloud might form of tie up particles, oil of droplets, and fine dust, High Altitude winds mix the air, results, and transport them far away. The this into mixing happens continuously as it does a variety of life forms in the arrow penton sweat to long body and currents. The place del boucher and manuela paula shay welk at the National Research institute about agriculture of food and environment in midland, in west and fronds collecting samples from this fund. A line strunk just positioned in the middle of the fields. Its essentially a joint insect vacuum cleaner. Theres a strong as so from the trap. The position in uh, i just met through it though, if it, by exact ammonia in a good 12 meters high, then on or 40 feet to be exact. Because its an english models was metal. Any of this at the which up to late, we dont want to use it to catch insects that fly 2 meters about the ground them. But rather organisms that were swept into the air goes and travel greater distance to the point they dont send. They dont have to do the picture so long since that that reveals more about the arrow pointing of the whole region for your website on the 13th this device wants to do it also nicer. A wednesday who is very good news. There are even lifeline because he wrote this is the nice weather amount of will take it to the land, the insane. So the largest organisms in arrow painted and they can stay in the for a few hours or several days and float up to 1500 meters depending on the size and the wind speed. The dr. Song saying everything that policy is by, agricultural Scientists Use the results to warn the farmers of clouds of a fade. So the past, the trap operates. Oh yeah, around the clock. This is really a lot to get to because its a sunny day use going up. I mean, im m as in a say, okay, another one is hiding investors, right . You know, one another a beat leaf, a 5th, the beatles and flies fonts. Even spite is a tremendous variety of species play a role in the invisible ariel by swelling above us. The comes on medium uh what about just the countless cells of algae and small presentations in the see the cubic meter of air above our heads. It contains so many different organisms of that, that includes the board on the wall and bacteria preventive, but also small insect spiders. Like daily news, well see that shes on sag design. Yeah. Its, its on the organisms, right. The winds like flying compet, the and gives them a chance to be nourished, to reproduce. And to, to find the weve known about the existence of arrow paint on to nearly 200 years. Which is naturalized Charles Darwin noted in his journal during his expedition to the galapagos in 18. 35. The spiders were entangled in the ships rigging many miles from shaw. And in the 2nd half of the 19th century, french scientist louis past due proved through a series of experiments. The particles were continuously suspended in the yeah, he called them organized coal puzzles as to is remembered, is one of the fathers of modern micro biology. Tobacco allows it strikes meningitis around that time. Scientists discover diseases could be caused by such and bacteria. A new branch of science was born and wrote biology. Scientists began comparing measurements in the same amount of that 55000. 00 bacteria were found in the bustling, dilute as a by lee in paris. But on the 7600. 00 were found among the trees in a box. In the swiss alps the hotel even advertised with assign the claimed only 25. 00 bacteria. The then it was the work of legendary pilot charles lindbergh. In the 19 searches he attached and it the save defiance to his pain and then flew over the icy landscapes of northern canada. Collecting a variety of bundles, phones, poland, and micra, l. G. The samples supported the pieces that living things can survive Long Distance and travel that High Altitudes. But in the years that followed arrow biology descended into obscurity and the organism suspended in yeah, somewhat so gotten the ingredients in satellite imagery. We kindled interest in the late 20th century. Scientists discovered unbelievable amounts of suspended micro organisms or she was so scared the push the hell. So im of the way down to the when you blow the dust off a piece of furniture, you see that its carried away with the airflow and things like that. Its the same in the atmosphere. Now, the mass of these particles is so small that once airborne, they stay there and follow the as, oh, i see, yes, feel, oh cool. Now a fond smile to lack researches, the inter continental transport of desert task. He says roughly 2000000000 tons of sewing or dust rise from the laundries deserts every year and circulate in the atmosphere. These gigantic dust crowns with the same via satellite images in the 19 ages. Aero biologists spend realized the true extent of circulating aero pine tone. No, but certainly i met you on, you know, i dont know just contains not only mineral matter, but in some cases also living organic material to give you micro organisms such as bacteria, viruses and fungi, meals as soon as the dust is kicked out, it carries this array of living micro organisms to completely new place this, which will be the, its easy for a bacterium, fungal spa, all virus to attach to a tiny speck of dust and take flight. The desert winds does up grains of sand blasting of tiny granules of clay on impact tons of dust and micro organisms. A sucked into room and columns, reaching a height of 3 to 4 kilometers the hold up a wall street. And we can track this dusk over Long Distances. Also the supers you satellite images can help visualize the formation of such a cloud over this. The hard as that within several hours, the cloud grows and starts moving to the area. I will say the only thing. Ill fast forward. Theres what youre telling me what goes set to close mazda pursue days later, you can see these huge dust mass is reaching the Atlantic Ocean. He of us, with a few days later, theyre already over western france. It will cuz theyll likely to send over the british ios or even scandinavia a propulsion was showing us coordinated ex, weather conditions high and low pressure areas. Boom and cold and current. Either cold, the desk booms in or blew them away. They foam and highways, but circle the, the a kilometer. If they task cloud can cross the atlantic within a week the, the atmosphere is a true transpose of like the book to them at yale and up the matter contains chemical elements. And in some instances, nutrients, the touch police desert does transports help balance eco systems on the earth surface. This increases the sofas or the tail the tiny organisms and arrow pine tone travel incredibly Long Distance is that High Altitudes. But how do they travel . And how do they affect the ground . The countless micro organisms eventually touch down somewhere on us of the body. The guidance emilio cas on manuel is in catalonia and researching what is known as micro bill deposition and its connections to climate change. Hes working on a major study of micro organisms in the atmosphere and almost with a key science by his research is in the spanish baronies the to see the just see the coming from out of the 2 dimensions of the metal were and an altitude of over 2000 meters where theres little interference from local air pollution. Im using pizza. We want to capture micro organisms thats right in the atmosphere and travel from continent to cutting it the gas in the office instead of going through them, done a lot more so that youll be going to do this on. We gathered rainwater in the collector for one week and the sample includes micro organisms and small particles. We collect these in a filter and bring it to the land and i dont know one of them which, which, which, which, which, which the most part people us get the most i can hear. You can see the particle. So like, you know, whats the best part of the water is clear again, because all the particles got stuck in our filter and was talking to a lot of people that sort of that because there are organic particles like bacteria, it fun guy, holland. And it was on the but also in organic ones like clay silicates and minerals that come from far away is almost because hes been in for a lot of them with us. What are some of those take us about a year and could be just from africa, for example, the 3rd which was transported them, yet my sphere system was washed out by the rain and the light. Thats what were capturing here. The water is probably running. There are thousands of millions of micro organisms in this building immediately means that the me unit in griffin is these continuous deliveries of micro organisms are a natural process that if a cod throughout us history, once the particles lined again, the tiny travelers have a Significant Impact on ecosystems some bacteria and help boost pond to growth by attaching to them and pulling nitrogen from the others, penetrate the soil, and recycled dead organic matter. Viruses and microscopic modes regulate animal and plant life. So let me throw and these will stick when theyll gain. When these micro organisms land in, they can colonize new habitat. We wednesdays, theres an excellent dispersal system for bacteria that im the, allowing them to colonize the entire planet. Theres small, reactive biological entities that land in a distant planet is whatever and create new life. Even even though theres already a, somebody thatll be the media cast them i yours team started micro organisms in rain want to the is and with the help of weather data, trace the arrow pine tons, pathways the scientists were able to show which region ocean all continent the streams of arrow pointing to them came from and they discovered some remarkable patterns of the in the summer arrow plant on tends to be local. It rises from the farmlands of spain and Northern Europe above cities, rivers and lakes. But in the winter, the major streams of arrow pine till him come primarily from the Atlantic Ocean bacteria and viruses cross the ocean within 3 days and to send over the mountains. Already had left the middle resort that it was going to be un, what you better when we analyze the initial results of storm xavier and june, we noticed in trends that recur annually, this was an amazing discovery. How is it possible that the same micro organisms appear at the same time every year . I see those up, but its gonna be moving. We know they travel over the sea or emerge from the nature. Here are some plants growing. The spring of this growing the summer months and the cycles are mirrored in the atmosphere, so used to speak last time, you know, quote in and im with of the streams of arrow pine tone and not some random mix of species drifting with no rhyme or reason. The microbial mazda is the rise and settle at the own cycles and seasons, just like bands, flowers, and bumble bee, the but given that it is the transpose of life, the atmosphere kind of also poses a threat. Among the multitude of microbes calling the skies a some to um say that humans can microscopic aero pine tone. Make us sick. The on the flip flop. Need yes. Most of the people used to talk about my as a medic. X relations when it came to airborne diseases. Also the prevention wasnt possible back then. The method of transmission wasnt really yet known, because that meant that all human afflictions, but generally attributed to the environment. You know, some of the, the failed to submit this real nice old notion of a noxious atmosphere that makes people sick, has some truth to it. We now know that all microbes and viruses floating into yeah, which can infect humans, animals and plants. But flu and foot and mouth disease can spread from bomb to bomb. With the help of the wind over several kilometers. A dead condition is can release legionella which causes potentially fatal pneumonia. The many fungal spawns that enter the atmosphere before settling in the soil. A microscopic taking time, bombs, the shopping. You visited, the visual, put those in a symbol. There are some pretty dangerous pathogenic, fun guy. The, to the hospitals are mindful of this because in soil, in sand and move during construction workers and their adverse wins. This is asked for deal a sports and other harmful molds can enter clinics and cause epidemic loading, unloading for you. What is it to them . You dont need to be sees of the genus as for dealers are found everywhere. Youre including in the atmosphere acute, or if they appear in large amount, theyre dangerous to him. You know, compromise that the gross, you know, the degree of what we keep switching to manage the science as shown. Pathogens can spread of a medium distances droplet infection of a very short distance is of up to one meter, such as the influenza virus or the virus that causes cobit 19 is also being proven. The font that isnt solid evidence to show that transmission happens over a Long Distances of several 100 kilometers. The reason for them to those very easy to few pathogens dangerous to humans can travel very Long Distance is so question deals that the corona virus was studied in the laboratory for its vulnerability and it turned out its very sensitive to alex to yeah, a cause did you be radiation and dryness, quickly kill and render a virus harmless when its suspended in the air outside optimal vapor tree. If i didnt think of it, the atmosphere is even more dangerous. But viruses than insects. Only one in a 1000000 microbes survives. Its trying to see by google and hold on to the activity, but theres a large numbers of bacteria and seemingly with some pathogens are not get a cause for concern because theyre mostly dead. The only most were talking about traces of genetic material. So spiral bacterial occurs acidic, but not a live virus. Is this into a box, the lives of people. The men say look, you know, its very rare for individual viruses or bacteria to make you sick. A lot. It takes a substantial viral load to become infected because luckily i bodies have Strong Defense and most likely to always low level who the follows the logins immune systems of vigilance. Now for the last most Infectious Diseases today, transmitted by a different kind of and pop the way through our planes. Passengers on board spread micro organisms all over the planet. In spring time, poland takes its ton on this giant at carousel pollen grains produced themselves. They often travel far and wide, and reproduce with a female gummy of other trees. This is beneficial to many living beings. The little med johnny, the pollen grains couldnt break releasing irritants, but make poland allergy is a widespread problem of the at the university of little in france, you called all visa and now the usual on studying poland, theyve captured from the yeah, theyre examining whether poland grains breakout more easily when they encounter at pollutants. And this guy over there so far, let me adjust this the live. What else did they put on the x to is this this poland has truly exploded on the national to credit. They know this is the sample from the books pulled and sees it, they could help cause thats where you can float the pole in this crack. So just to pay for what is what is a subset. So not long that its deflated. The their protective membrane is really shred, okay . If they how long they should get this, the one for the next week. I see its near, we see the broken pole in a for which lost its original reproductive function. You can also see the release of the small particles, which are dangerous for people with as minus. Thats it for by clock, as its immeasurable because all to become friends. Of course, not all pollen. Greens in the atmosphere are shown here used to mall. Our job is to count them difficulty. Whats the percentage of damage . Grand design, explore and not a harmful to how its curious cuz its interesting to for us on the dates, the researchers want to better understand what happens between a poland gra
