the people learn to classify small handful of animals as edible and all the rest they classify as disgusting. w series about our complex relationship with animals. the great debate, what you know on youtube, dw documentary, the,

the vegetables, parmesan cheese. the mediterranean diet is very healthy. today, pasta is on the menu with a very special pesto whipped up in the laboratory. you can't get the ingredients for this recipe in any old grocery store. it's made with a special micro algae produced here for research purposes at the phone. the institute instruct got up to a key low of it every day to multiply algae needs just a bit of salt water, the right nutrients and a lot of light. and different types of allergy can be put to different uses. like kind of the senior stuff here so you can make a range of things from now. do you like to take this carbohydrates fatty acids for? then you can also use them to break down various substances like nitrogen and waste water equipment or in order to recover c o. 2. konstantin slick is writing,

his doctor will faces on microbiology like to species he's going here at the university of holland. i'm say, or doctor, let me try for a new dog has a number of special characteristics. it contains many of the same substance as found in fish, including proteins, keratin noise, and a central fatty acids. fisher rich in these substances because they eat the marine plants, which is why the scientists are looking for ways to turn algae directly into food for humans. and important goals as the oceans are increasingly fished out of it as good as we have to start thinking about how we're going to feed people in the future. protein is a major issue as our omega 3 fatty acids. that's why fishes are recommended food stocks are declining, so we need alternatives. that's why we launched the algae project of that. macro l g. c, we is plentiful, lendy oceans. the micro algae res tier are much smaller though. and they've been dried into nutritious flakes with the fishy to a,

just like the fish that he did. the researchers hope their products will soon be produced commercially, and can replace up to half of the fish that we eat. some fish replacement products are already on the market, but they generally try to imitate it's look and taste for size that's put up to a mutation at the moment. fish replacement products imitate fish, light can tune up. so there are products aimed at deacons and vegetarians, but nutritionally, they're not an alternative to fish. they're just convenience products that imitate fish, dr. can you fish any t m l g can provide a real nutritional replacement for fish, but it takes time to gain approval as a food product in the u. until that happens, the researchers will keep carrying out tests and sell cultures. they're studying potential toxins and allergenic substances which can be an issue with proteins. so

medical supervision during the test process is a modest. the scientist also carry out blood tests to determine whether nutrients from the energy or metabolized to hide the unusual flavor in the tortellini. the algae are mixed into the past of filling out a bit of parmesan and fazel edits ready to sir the hosting fuzzy to cool. you can really taste of hazel and wild garlic. um, and if you really focus and you could also taste as good of algae, but just a tiny past life, i could just make type of a. i can just call this is how joe, there's also the health aspect. it's great at the plaza that we all liked to eat, can be a bit healthy or a corner, some concrete out of the light on this, please. i had to, if you had some of this, how it or you can just mix it into things like test out for probably other things to like smooth it and then you could probably also drank it. this would totally

need to point o. s super food made with algae that could make the mediterranean diet even more nutritious. the youtube and internet stars loves them super sweet drinks in bright colors. the ice tea isn't energy drinks are very popular with children and teens. luca and us and just us enjoy playing soccer and that's 13 and 14 years old. they're a big target market for energy drinks. and so they say they like to drink them sometimes, but they usually try to hide the 3 add that they've only actually bought energy

drinks a few times, but that some of their teammates are really into them 6 months a year for some of them fill up their water bottles with a drink. so the coaches don't notice in the shop. i know a couple of people more even who buy a red ball or something like that. before school. they drink it at school or sometimes after school after school, and when they finish one can they pull out another in germany, stores have shelves loaded with energy tracts along with a lot of sugar. they usually contain tyrene and plenty of caffeine. and there's no age restriction on purchasing one, even children can buy them. mountain hope corvette to is a pediatric cardiologist who's seen patients who down several leaders a day. and i'd say thing to sleep, but sometimes they tell me their heart is beating really fast, which makes them really nervous voice. we also see some people who end up with high blood pressure and condensed a pool. and in some cases, when they consume a lot of these drinks regularly, an ultrasound reveals thickening and the cardiovascular muscle tissue, which is

a very serious issue with what's happening with this helps us the systems here outside the before. in severe cases, the young people can even suffer from life threatening cardiac a ruby r. u has loc works for a consumer association. she visits schools to explain to young people why energy drinks can be dangerous. labels are often hard to read. that's most my thoughts actually, so you really have to hunt for what's in it. often there's a caffeine morning on the back saying the drink isn't suitable for anyone who's pregnant or nursing or for children. it would be better if these warnings were on the front of the account and easy to see a little about 20 cubes of sugar in some $160.00 milligrams of caffeine or in just half a leader of energy drink. just a single can contains more caffeine. then a young person who weighs 50 kilos should consume in a day. that's why many doctors and consumer advocates say the energy drinks should

be banned for kids. but so far the german government hasn't made any move to limit their sale. and despite their health risks entered the drinks are still hugely popular among children and teams. the in 2018 the beverage industry agreed to reduce the amount of sugar and soft drink sold in germany. but a study from early 2024 shows that since then, manufacturers have cut sugar contents by only about 2 percent the how much i'm just saw. we took a look at how the average sugar content of soft drinks in germany changed or compared to what's happened in britain in the last few years. in the key result of

our study is the britain reduced their sugar very fast and quite substantially. whereas germany made very little progress calm for i'm come to in fact lies, olives, avoid sink. co author the study. he's the political director at the german obesity society. germany is one of the world's biggest per capita consumers of soft drinks on average. people in germany drink more than 80 leaders of sugary drinks a year. teenage boys between $14.17 can, so even more on average up to half of liter per day. that's way too much export say teen should only drink half that amount per week, not per day. and for land, the german obesity society studies diseases that are associated with a condition. soft drinks are a key factor in serious weight. gain is in direct to our that's because when we

drink these products, we're consuming calories that the body doesn't really recognize as calories. meaning they don't lead to feelings of fullness, technical, and before that's why these drinks promote weight gain. that's what that's so in terms of health policy, we really want to reduce the amount of sugar and soft drinks, which is the best. it took off, nominally soft things, except for the u. k. as an example for how it could work. soft drinks they are used to have about as much sugar as in germany. but levels of now dropped by 30 percent . the united kingdom is one of about 50 countries that have imposed a tax on sugary drinks. so does that mean there's a difference between of brand name, soft drink and britain and in germany? money each dusty. so you can see that the sugar tax and bread has caused strings to be reformulated, even in drinks like santa and sprague, you would have far more so than anything we see here in germany. as all the

manufacturers don't explicitly say this is due to the tags stuff. it's pretty clear when you look at how the formulations have changed into 2 countries. all the toys makes the store take us up to one and to make a german soft drink. manufacturers have done little to voluntarily reduce sugar content. so attacks would probably be far more effective. let us read why on the, how did the eyes of spiders and all the most spiders have 8 on?

so if you have only 6, generally they have 2 larger principal eyes and the rest are secondary eyes. they to give spiders, almost $360.00 degree vision, which they need. that's because spiders have no neck, so they can't turn their hands to see any predators or prey. they need to turn their entire body's jumping spiders need especially keen vision. that's because they have various sets of eyes do different things. the front hair identifies detail and color coping it to determine whether a target really is potential prey and the secondary eyes. calculate the distance to it and it's direction of motion. the other spiders, like yellow sucks, spiders are not turned on. so they need to have good night vision when it comes to insects, scientists know quite a bit about how their eyes developed. but so far,

researchers haven't studied the eyes of spiders in as much detail. in one study biologist looked at spider embryos to see how their eyes develop. first, they had to remove the tiny arachnids from their ex sacks. the scientists were also interested in the genes that determine how spider eyes develop. that included comparing their activity to the activity of genes that determine i development in other groups of animals. there were a lot of similarities. the researchers found that the same genes that determines the development of others sophisticated ice structures and other animals were also active in spite or i development. they were involved, for example, in the development of the compound faceted eyes and insects. these finding support the theory that the astonishingly diverse types of eyes found throughout the animal

kingdom could potentially all be traced back to a common ancestor the . this square in front of the ancient village church in the small mountain village of co, coolio and the heart of the italian region of a brook. so even when it's cold and miserable, villagers and visitors from all over the country gather here every year in may to celebrate a very special festival. if you manage to fight your way through the crowd,

you'll discover a fascinating aspect of this celebration. the snakes. in the weeks leading up to the festival of locals, captured over a 100 of the reptiles in the mountains around their village. said to be over 2000 years old. the tradition is a bizarre mixture of religious festival and pre christian ritual. animals like these non venomous 4 lines, snakes are draped over a figure of the many co, the villages, patron saint. then it's carried to the village in a festive procession. a benedictine monk who lived over a millennium ago, dominican who is said to have george people here of snake bites and toothaches, biologist mounting because he has also come to cook. oh, the director of the max conked institute of animal behavior is interested in the wild snakes because cordova is also located in the middle of an earthquake. who

studies quite protection and animals. cute animals can do much more and that much better and then we'll never be able to do with devices. do the adjustment shopping . bit all over the world. stories have long been told about a mysterious $0.06 and animals, one that allows them to react to impending natural disasters like earthquakes. among the best documented of them is this one in high ching, in china, in the winter of 1975, a large number of snakes came slithering out of their burrows when they should have been hibernate soon froze to death. the conspicuous behaviour caused the scientist to urge that the entire city be evacuated, not long afterwards. a severe earthquake struck is an interesting story, certainly, but a story isn't the same as scientific proof. so researchers have until now remained skeptical to blame,

possession of the problem with naturally occurring events like this is that everyone thinks afterwards that something must have happened before hand. so the news, but we simply have to nail down with hard data, whether that's really the case. that means we have to measure what an animal is doing before and during and after the event. that's what because the wants to try here with snakes with the help of cutting edge technology. using miniature computer is known as bio loggers, scientists canal tag animals permanently. and measure interesting data like their migration roots, heart rates, and the temperature in their environment. they can also gauge the animals energy consumption. that's a crucial parameter when it comes to documenting unusual behavior in the run up to an earthquake before the snakes are released again after the festival. the researchers will implant transmitters under some of their skins,

marching because ski carried out a 1st series of measurements with different animals on a farm and input. so using bio loggers, he measured and compare their energy consumption over a period of months. those energy consumption measurements are charted here on the blue line and the earthquakes recorded in the region are represented by the dots. and there are correlations. see dots inside the data shows that the animals have a daily reduction. at some point they're more active and then they grow less active again. but hours before an earthquake before a major earthquake and they exhibit completely crazy behavior. it's like in a stock market crash fight. they all go crazy and it's not just one of them, but all of them and i am so alex is on the now is to expand on this initial data by tagging, larger groups of animals at different locations, as well as a wider range of species. like snakes, which appear again and again and stories about or as quakes distortion. this is

often research. it's often the case that new things take a long time to really be accept at least that it's the same with this. so if you could make these observations 10 or 15 years ago, but to me and now we can for something i know most of them, this couldn't be, it may be the snakes will come crawling out of their holes before the next big earthquake. and if they do, researchers will be able to record every movement, acquiring the 1st real, prove of a still legendary 6th sense, the

constructing new buildings that are earthquake proof is no problem. so when the ground starts shaking, it's actually very cold buildings that post the greatest risk they to can be made or as quick resistance. however, thanks to several inventions, the 1st method sounds straightforward, the engineers to their inspiration from an art installation, as well as beautiful in the vicar, the german apartment building was wrapped in fabric by cristo. it was amazing how quickly a building like that could be covered. all obviously the art installation was not our point of interest. it was the idea of using fabric wrap to protect against tremors. the wrapper needs to be both strong and flexible. the took scientists that the kinds would institute of technology years to develop the right material and to establish how best to attach the fabric to the building. the window,

the norm, this is the basic version is still completely white. it hasn't even been coded yet, but you can see the general idea a month, 180. the materials fibers run in all directions, helping to protect the mason rate. this model house has been placed on an earthquake simulator. it's half the size of the real thing. it is coded with the protection system developed in germany. the system works like a cast for a broken lab which stabilizes the bone in the same way the plastered in earthquake matting protects this building while even allowing it to sway during a north quake. in another experiments, the simulator is turned up to the maximum, but the house remained standing. this experiment with a hydraulic ram shows how a normal wall on the left reacts to an impact while the projected one on the right

remains intact. cost as a company in southern germany that specializes in producing book binding materials here they know all about specialist fabrics for technical tech styles as they're known that need them the perfect partner for the researchers in causal the firm develops the fabric for the earthquake protection systems. using glass fibers and polypropylene with a special finish. the mixture is easily applied. first comes a layer of plaster developed with a specialist farm from italy. then comes the earthquake protection mat in. a 2nd layer of plaster is applied on top and the job is done. people don't have to move out during the process. normally only the outer walls are wrapped. the system even works when construction has been botched. deep on including lives near lake concepts. the wrong bricks were used for his home, a survey or was called in to inspect the house. and he noticed something even worse,

thought it would all stop. and even in addition to a number of construction defects, the survey are found that the house was not structure really sound. so it wouldn't be earthquake, put in all the hallway could have been reinforced. but that would have been very costly and we would have had to move out for 6 months. and the worst case, the whole house would have had to be demolished and it's a new house is always to him and the bones had to be completely strapped. and the plaster installation removed, but at least the going i was didn't have to move out today their home looks completely normal, but it's earthquake proof the book binders in southern germany have also worked with a cause with researchers on another protection system for art quakes. this one is for walls that are not load bearing. it's a covering made from glass fibers and a selling well. when a quick begins, it can give occupants a few valuable seconds to flee. any painter it can apply it. the secret lies in the

patented wallpaper paste. it's an especially tough but flexible, adhesive of that cost works with an italian construction chemicals group. the manufacturer is the adhesive in markets the entire system. italy has had numerous earthquakes in recent years, but the system developed by firm up high has held up well, including the powerful quakes of 20092016. that's okay. where those are the features. so, but with the quality for many public buildings, especially like skills that hospitals have this protection when the quakes it, which is c by man, the. so we've been able to prove that the system works the list because to assist the people who were in the buildings at that time, also made it out on hard feature. so notice she though she is equal to the residence of this apartment building in milan, where the system is now being added will also be better protected against earthquakes. and the future vendors. target protection systems made by the german

company were also installed in some buildings here. before last year is devastating quakes. and we could see after the earthquakes that the protected buildings had virtually no damage, while some of the other buildings in the same street were severely damaged. however, they happened to scan the room was hard hit by the quick, the damage was wide spread and devastating, but the municipal administration building was reinforced with the invention from germany. and the old palace is still standing today. do you have a passion for science and health? check out dw signs, contract talking. why do something does not get drunk? why do gravitational waves squeeze out bodies? and what's the perfect queue of football by find beyond says yes,
