says 25 years to implement the greatest revolution since the tune of the industrial and replacing fossil fuels with renewable energy around the world. is this really possible documentary renewable task, november 25th on d w. the? what do you think he's trying to tell us? being able to talk to our fellow creatures is an old dream on one that still seems a long way off, even with the closest evolution re cousins. but the chimpanzees have something like the language. and if they do, could we decide to where it would that help us to better understand them?

that's an older exciting topics this week in dw signing show. welcome to tomorrow. today the humans can talk tapes can well. so we thought no pollution or a biologist maya, know who, when others are challenging this dogma, we accompany him to the zoo, and this was city of bozza to listen to chimpanzees. anything here, then same routine right now and are getting excited because there is some water coming out and the alpha male, he's also been reaching yeah, he's displaying any old test step as well. so he's just trying to associates dominance and whose status and the group is chimpanzees communicate with gestures, facial expressions, and highly specific sounds. but they don't form spoken syllables or words that we humans can understand. so,

cracking the code of exactly what they're sharing takes patients. first of all, you call ask them what do you mean by that stage that can you just have to reserve and try to understand when they do produce a specific cool assisiting book innovation? when is, what is that context? what does it mean? and you can only understand that by observing them prime a researchers have been doing that for decades. and they now know what sounds chimpanzees make in what kinds of situations there's even that kind of chimpanzee dictionary. my hello, who is looking into how the apes combine these noise? that's what we're getting at now is really understanding is actually going be on the dictionary and go into the grammar and the syntax of these ellen and to get his current research is based on a recording made 10 years ago. when evolutionary biologists alarm the female gen

with a fig snake, the snake is around their, of the snake presentation. and now, so this, this and she's standing up, so it's by people. and she's listening toys. and you can see she's promising the along who's with her needs and it says, look, i understand in a tone barely audible to humans, she alerts the others and now she's producing the about the combination of the cries, who, and was seemed to cause other chimpanzees in the group to climb a tree in alarm and check out the situation from above. so did they do so because the elderly chimpanzee warrant them for, for another reason. to find out the route developed a new experiment involving a recording of the who was a combination. like after this and quite carefully because the around who's quite

soft the who. oh and so that's the alarm. who food i did was in uganda. he played this call to free ranging chimpanzees over loud speakers without a dummy snake in the vicinity. and it will play and right now i'm just heard it. i know he's looking in this because he's just turning, he said, and i was getting the speaker that here he alarmed by the who, why i called the gym pens. he performs the typical behavior, draining on a tree, and after is draining on a tree thing of the tree and down that is typical and to say to havior. fortune has the ruined his team repeated this experiment on over 20 chimpanzees in uganda, and it always had the same effect. so it's the 1st time we have everything that

same things, these understand a cool combinations the same way we understand what the meaning of the phase is based on the meaning of the words within the phrase. so do chimpanzees also have language for troy? we thought was unique to humans. larue doesn't like to describe it as that, because he thinks the precursors of language started to develop some time before modern humans began to evolve the evolutionary branch leading to a wrong good tongue split off 1st. then the one leading to gorillas, the common evolutionary line to let the chimpanzees and humans diverged about 6000000 years ago. so as larue is correct, communication based on combining sounds would be at least that all future experiments. most no show whether chimpanzees use other sound combinations to communicate. and also whether and how body language plays

a role. teams actually have quite a complex focus and communication in, in the general domain as well. even facial expression is quite complex as well. so is just the entire welding and self just trying to send these communication. it's very complex and we're just yeah, scratching of the surface right now. but for my in the room, one thing is already clear. jump communication is closer to human language. then we once believe the lesson and them all has in common with us, the more difficult it is to feel empathy for the taking extreme example, the locust bask numbers of them sometimes appear destroying crops and leaving devastation in their wake. but what do individual locusts get out of the behavior? why do they come together?

deforms huge storms. and if we knew why could we steer them swimming. lucas? millions of them, stripping trends back in the summer of 2023 quarters of kenya was badly affected. for the people that it was nothing less than a catastrophe. biologist, a not cousin folks from the university of constance was the she remembers. well, the insect likes, overwhelming scale. anyway, jania, we were really surprised how large the forms were, how big the groups and how since they were one plans, they could find thousands and thousands of individuals. so i heard about it and so they do as of all the states. but i did really, could you also believe how big of this one was? because in folks as a new or biologist, she conducts research together with a husband in cousin who heads up the max planck institute of animal behavior. the 2

sciences are particularly interested in how lucas communicate with one another. how they form groups and how individual animals can influence the behavior of an entire us room. yeah, i'm hoping who is better understanding better understand what drives them to gauge with drives tend to move, what drives them to migrate, and when, what queues they are attentive to and the environments will help us to better understand as predicts in the future, we use a range of technologies to study this behavior from the imaging have what we can find individuals with extreme precision in the fields and using new concepts, a vision of the truck, animals actually in the not so environment. it's basic research in a still launch the unexplored field in pursuit of pioneering results. the biologists have developed a range of unusual, technically complex experiments. the,

for example, those that take place in the imaging, kind of a many hours help and stick mark is on the backs of 10000 lucas more than ever before. attempted other lot based experiments looking at swarms, going to be involved developed a 100 of the insects the stick has shouldn't interfere with the lucas movements. we've never been able to get lucas, the full, not full swarms before. and the last no one has anywhere in the world. and by putting together $10000.00 individuals here and there's lots imaging hung up for the 1st time ever, we can do. so they formed these real not sophistic swamped. and why is that in full sense? well, it'll allows us to use these new trusting technologies, understands how the individuals interact with each other. local interactions over the scale of centimeters give rise to swarms that can extend of a hundreds of square kilometers. this woman's digitized,

every dots on the monitor is a low cost every line traction individuals part of the data was recorded by an elaborate system. 30 cameras film, the small amount of 100 frames per 2nd for a week. the imaging hang up provides up to more conditions. the temperature is kept at $28.00 degrees celsius. lights has the same wavelength as in nature. the stick is used for the 3 d evaluation on both during the insects and every evening. food is laid out for the school. the big question is, who's following? who? the so i'm has no consistent leader. and this has been again reported from field observation. but i think this is the 1st time that we are using empirical data to validate that by actually tracking the individual lucas, that is one means, as i think that'd be, have preliminary evidence for the other thing is about the social conditions. so

again, previously people have seen in the field that lucas that go ahead of the band list, sometimes done back and returned to them. so this seems to be some sort of social attraction or social condition that is pulling the fence and milk is back into the band. and this again, we have some evidence of flawed from the embed code to understand the bigger picture, the research just have to look at individual animals, how lucas movies and how it reacts to its immediate environment, have an influence on the entire room. with this experiment, the scientists are trying to figure out which new role impulses make a lucas jump or run those inputs in as so i'm interested in the risk avoidance decision. so on to examine that and see, show the animal in approaching danger. it's just a black object that's universally seen is a danger. i can have the virtual it's form react here and then see if the actual creature reacts to the swarm or,

or if it reacts to the stimulus of all those together. and we'll see why look the same time i can measure the narrow signals i sent off. no, no not is not offered. when astonishing thing about lucas williams is that they appear completely unexpectedly, seemingly out of nowhere, not cause in folks, and had seen that for also looking for the key impulses that concern individual animals into members of a swarm. to do this, they put individual lucas into a kind of 3 d cinema that they are confronted within the control that the research has can influence that will. this system is a custom build setup, which is the only one that exists. we designed it specifically to start the locust behavior and to see whether we can what are the, who is the governing locus marching direction. while the locust is marching, the research has recalled the speed and direction. it's moving and looking for data problems. they hope to provide insights into how individual animals influence the

swarm is a whole and maybe one day of a clues on how to prevent swimming in the 1st place. the observing animals and the natural habitats isn't easy either. fish, for example, take off or dislike to selling this danger. like when the times a tries to creep up with a camera to stop them from fleeting, it's important to keep a low profile, stare up as little sand as possible. this works especially well if you have fins like this route, thoughts which can slide autonomously through the water for up to 2 hours meet dell, an underwater robot. it looks like a fish. it was developed by mechanical engineering students. this was federal

institute of technology zurich during its dives the robot films that surroundings and collects what are called e d n. a samples. genetic traces from things like excretions that organisms leave behind. the team helps bell will provide them with more information about bio diversity and the health of marine ecosystems. so our idea was to create a platform that actually fits into the system and that gets accepted as part of it . that's why we then develop a fish that has like a vision, is also accepted by other re, creatures. as an official, just under a meter long tail, navigates with the help of a i. the marine robot is propelled by a flexible silicone fen. fell, moves almost silently, and creates a very little turbulence. if you look at the way that b currently going into the oceans, that delta lots. i the amens under water vehicles. um, but they are definitely very disturbing and they're certainly not made to go into

these more delicate environments where we would love to get to the didn't the from the depths of our goal. and do you want to really go and then the us simons. this is like a spite, it's just really t coming in and being a spy on the marine life bell and other robots like, it could soon be used by marine biologists around the world. and by the way, we've just launched a new tick tock channel. and we'll take that there we answer your questions and clips that are fun, accurate, and to the point. but also based on the latest research, what did discovery even more from the world of science, then follow us at dw science trying to make a big leap from the depths of the sea to the depths of space. where you'll find the pillars of creation. a striking formation of dustin gas,

samuel oma from uganda, had a question about them. what uh, if she dies over creation, how far are they from the uh, is this your permanent oh, each 10 years we've taken so what all of the parents of creation and how are they changing over time? huge columns of stella, dustin gas, suspended in space about 7000 like years removed. they go by name the pendants of creation because new style phone in 1995, the hubble space telescope, deliberate, this shows formation one of its best known images in the columns that enveloped in a yellowish haze. geishas my time and space stuff. so young start screaming inside the pillars, released huge amounts of radiation energy that causes the dustin gas to glue

the different telescopes of set the sites on the vast dusk images from the spits. the space tennis group showed the columns in the infrared spectrum, revealing the traces is of a cosmic drama, a cloud of hot gas and dust. it might to come from a stop that exploded about 6000 years ago. the, in fact, the show what he may has already destroyed the pillars of creation. even though they can still be seen in a couple of images from 2015. that's because light from them takes 7000 years to reach us. the infra red images allow us to see through the dense dust clouds in the columns of transparent silhouette against the background filled with countless stones. the dis line reveals the

forces at play during stop. it properly originated in a gigantic stream of matter, ejected from a solar system that still in the early stages of development, the astronomers continued to be fascinated by the pillars of creation. no wonder then they were an early target for the james web space telescope as well. its images have revealed more about the turbulent this is new stones and make the pillars of creation shine in even more spectacular splendor. or if i was let is read, why are they on the video? do you have a science question for us, then send it in as a video, text or voice mail. if we answer your query on the air, you'll receive a little surprise as a thank you. go on. just ask the

strong them is also look up at the sky from the surface, but the sphere in weather can get in the way of opes evasions. so when placing a telescope location is key, the highest to come, a desert in chile provides optimal conditions. here is nearly always dried, clear and cloudless. it to him is never rains. and cities that could spoil the night sky with auto official lights of far away. during the day it looks like the surface of mars, but at night this place turns into a paradise. at least for astronomers, i'm in the common deserts in chile, one of the driest places on of the sky here is clearer than anywhere else. so it's ideal for the world's largest telescope, stay 1st and foremost, the v o t, which is contributed to nobel prize winning reset. the very large tell us go for b,

l t for short is one of the most important optical in for read telescopes in the world. famous discoveries made with it include the black hole at the center of our galaxy and evidence of an expanding universe. european southern observatory astronomers, susanna run to takes us into the nerves center of one of its 4 main telescopes where everything is being made ready for the nights observations. a few less tests are running before the dome opens to the telescopes, huge eye on the sky. the past life takes here is complicated so that it's not saying a me to main mirror helps just one end of the lp ones. what happens is the light comes in from mountain. the unit of the most in him is often from the sky. it hits that may mirror electric, yet is reflected back to the 2nd mirror of the in the black cylinder with dust. i

mean, that's been reflected back to us, the mayor of the good, definitely up in that. tell us, sticking out of the main member of the box, what do we need from this? the mirror of the light is reflected into the instrument, the records, the centralization of silence. when the sun goes down, work begins up on several past on a mountain. when everything is ready, most people here enjoy taking a break for a special tradition. enjoying the sunset together is owner. the sun is almost set and the sky needs to be dogs, so we can watch the stalls. i don't want to be, so we just getting started yet, get this listed. the night shift starts with dozens of measurements. everyone is highly focused. isn't to increase is to be able to control room where they control everything that happens up the with the telescopes. every single telescope has its own area and that's where the engineers and scientists control it split us

to the school. susanna rundle and meet shift coordinator stuff and me, scott, who's in charge today. he's currently checking a measurement moment time for both of you right now. we're observing a galaxy miss missing 833. and it's a galaxy where there's quite a bit of star formation going on. and astronomers are very interested in understanding that star formation. uh, these are standards dental to 15 with health from various filters. the in for read images give rise to impressive shots, a distant galaxies, like msu, 334 click. those are objects here in our milky way, like the covina, or the, or ryan that'd be less the because the atmosphere causes light to flicker interfering with observations. the astronomers have figured out

a way to adjust for it the laser guide star. the laser slaves is short, high into the sky, creating an artificial star 90 kilometers o avenue, which we then use to calibrate on measurements to produce a sharp image. which is the adaptive optics and the v l team that we can get images almost through shop is a james web space telescope and in the future will be able to change even sharper images room has been made on the summit of nearby cetera ottoman zone is for the extremely large telescope, d e l t. when completed, it will be the largest optical telescope in the world. what it's huge and 60 meters in diameter meat, but that's nothing compared to what the doom of the telescope will look like when it's finished. it will be 85 meters high, it's me to hook side. the gigantic main mirror will be 39 meters across

and enable a completely new kind of astronomy. these and causes a giant leap forward. maybe i want to look out further into the universe and understand more about it. on the c a l t will be able to distinguish us like planets. for instance, i'm the right mosquito. see of a point. yeah. so it could tell us if there might be an a $2.00 out that is by publicity, the world's largest telescope is slated to start searching at the end of the decade . but the lp will also continue to look into the bit questions, tend to develop new technology like the v l t i as a huge center for romage or the optically conducts the measurements of all for telescopes yeah, light is taken and correlated with respect to the mirror as an yes, a wave chris, a superimposed wave chris and it's done it. wavelengths of 2 to 2.5 micro meters,

10. they have to be put together very precisely with these mirrors, but it's, it's really a mind boggling. achievement, localize the tongue. i as in how from the max punk institute for extra terrestrial physics. and if the technical university of munich works with the v l to he and his team developed an instrument, they called gravity. it made visible the motion of the stars around the subject areas, a giant black hole at the center of our galaxy. the work also provided more proof for hind steins, general theory of relativity must be its most. what we want to measure now is whether the prediction is correct. what is, what is the black hole really only determined by the rotation of space, time and mass, or a space time, strangely deformed? who wish for form c, i use it maybe egg shaped or shape like a clover leaf. you could determine that from the shape of stellar orbit gordon

vaughn. from this, you're holding the bicycle on black holes will play a star enrolled in solving this big physics puzzle. i have denied that, so we have time for on tomorrow today. the science show thanks for joining us and see you again next week. but for now, the, the, the, the
