is it all say what crazy the . ready the

holland 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 or for 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 countries in your stuff here. so you can make a range of things from allergy likelihood, glenda's, 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 con sensing slick

is riding his doctor. all faces on microbiology is like the species he's going here at the university of when i say or doctor little try. core nutone has a number of special characteristics. it contains many of the same substances found in fish, including proteins, keratin noise, and essential 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. if it is good up, 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, weight is plentiful, and the ocean's the micro algae res tier are much smaller though. and they've been dried into nutritious flakes with

a fishy taste. just like the fish that read it. 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. push as that's put up to many, 10 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. what up to the fish in each young algae can provide a real nutritional replacement for fish, but it takes time to gain approval as a food product and you until that happens, the researchers will keep carrying out tests and sell cultures. they're studying potential toxins and allergy and substances which can be an issue with proteins. so

medical supervision during the test process is a modest 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 pesto, filling out a bit of parmesan and fazel edits ready to sir the hosting fuzzy to cool. and you can really taste the raisal and wild gar like that. and if you really focus and you could also taste of good of algae, but just a tiny past life, i could just make type of a. i can just call this is how do you there's also the health aspect. it's great, it's a plus that, that we all like to eat can be a bit healthy or a course uncomfortable of items. please go ahead 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 drink. it would totally need 2

point. oh, a 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 teas and energy drinks are very popular with children and teens. luca hunters and eustace enjoy playing soccer and at 13 and 14 years old. they're a big target market for energy drinks. and so they say they liked to drink them sometimes, but they usually tried 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. some of them fill up their water bottles with a drink, so the coaches don't notice 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, knock this one 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 is no age restriction on purchasing one, even children can buy them. mountain hope corvette to is a pediatric cardiologist who's seen patients who are down several leaders a day and same 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 the 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 that we're having. this helps us. the system is here accessible for it. 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 montage actually. so you really have to hunt for what's in it off, and there's a caffeine warning 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 can and easy to see a little about 20 cubes of sugar and some $160.00 milligrams of caffeine or in just half a leader of energy drink. just a single can contains more caffeine than a young person who weighs 50 kilos should consume in a day. that's why many doctors and consumer advocates say that 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 content by only about 2 percent the how much i'm a solid, we took a look at how the average sugar content of soft drinks in germany changed or something compared to what's happened in britain in the last few years. the key

result of our studying is that breton reduced this job here very fast and quite substantially, whereas germany made very little progress. calm. so i'm coming to in fact like oliver, we think a 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 sugar. we drinks a year, teenage boys between $14.17 can. so even more on average, up to half of leader per day. that's way too much. experts 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 that 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 the feelings of fall most people 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 months each dusty. so you can see that the sugar tax and bread has caused drinks to be reformulated, even in drinks like santa and sprite good 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. so it's pretty clear when you look at how the formulations have changed into 2 countries, all the toilets, this talk, you got that one and today can tom, german soft drank manufacturers have done little to voluntarily reduce sugar content. so attacks would probably be far more effective. let us read 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 help give spiders and was 360 degree vision which they need. and that's because spiders have no neck, so they can't turn their heads to see any predators or prey. they need to turn their entire bodies. jumping spiders need especially keen vision. that's because they have various sets of eyes do different things. the frontier identifies detail and color, hoping 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 or in one study biologists 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 at 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 and 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 the 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, the 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 conclude on the director of the max punk institute of animal behavior is interested in the wild snakes. because coolio

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. shopping. be of 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. assume 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 hands. 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 computers known as bio loggers. scientists can now tag animals permanently. and measure interesting data like their migration routes, park 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 mounting

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 and 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 wouldn't be for a major earthquake and they exhibit completely crazy behavior side. it's like in a stock market crash, they all go crazy and it's not just one of them, but all of them. mm hm. i'm 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 into flesh. and 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 and did these a bit, but to me and now we can for something i know most of them is couldn't be, it's maybe 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 started 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 english because it 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. that 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. this is the

window, the norm. this is the basic version is still completely wide. it hasn't even been coded yet, but you can see the general idea. among the d. e. d. the materials fibers run in all directions, helping to protect the mason break. 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. and 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 that the house remain. 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 are now. that made them the perfect partner for the researchers in causal. the firm develops the fabric for the earthquake protection systems, susan class fibers and polypropylene with a special finish. the mixture is easily applied. first comes a layer of plaster developed with a specialist firm from italy. then comes the earthquake protection matting. 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 route the system even works when construction has been botched. deep on gleaming lives near lake constance. 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 then in addition to a number of construction defects, the survey are found that the house was not structurally sound, so it wouldn't be earthquake for the hallway. could have been reinforced. but that would have been very costly and we would have had to move out for 6 months. in the worst case, the whole house would have had to be demolished, and it's a new house is always saw him at the balls had to be completely strapped around the plaster and installation removed. but at least the going i didn't have to move out today, their home looks completely normal, but it's earthquake proof the book binders in southern germany. you have also worked with a cause with researchers on another protection system for arch quakes. this one is for walls that are not load bearing. it's a covering made from glass fibers at 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. that cost works with an italian construction chemicals group, the manufacturers, the adhesive in the markets, the entire system. italy has had numerous earthquakes in recent years, but the system developed by for a map hi has held up what else? including in the powerful quakes of 20092016. that's okay. where those are the features. so, but with the white people, the many public buildings, especially like skills and hospitals. we've had this protection when the quakes hit switch and see what man the so we've been able to prove that the system works, the live feed. gotcha. of course, the system people who were in the buildings at that time all sort of made it out on hard. did you feature? so no, she to she it. and she called us up the residence of this apartment building in milan, where the system is now being added will also be better protected against earthquakes in the future. then there's turkey protection systems made by the german company.

we're also installed in some buildings here before last year's devastating quakes. 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 by the skin. the room was hard hedge 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 d, w, science project talking. why do something does not get drunk? why do gravitational waves squeeze out bodies? and what the perfect cubic foot by find beyond says,
