so the protest movement i did not think so many women would send me the photos. she's there motivator. all of us hire on this one must be the and she won't give up to watch the stomach for public took my brother hostage a few days ago. but at the trying to sign in the scene of the job, they won't be silent. starts june 3rd on dw we cons exactly say that we treat the problems world with respect we are constantly exploring science at every opportunity, and we try to optimize them through breeding engineers like modification. the plants are extremely sensitive to external factors like noise, for example,

the hello and welcome to tomorrow. today, d, w, science magazine. most people don't give enough credit. that's a mistake because these extensively simple life phones have many amazing abilities of tool for them. it's also a question of easing o. b need to around 800 sounds bases are kind of varies. they can catch flies and can even eat small pieces of meat and they display in large variety of different strategies for catching prey. carnivorous plants everywhere you look 36 years ago. that file kind of founded the carnivorous plant nursery in the southwestern town, a fine time now the largest in germany. and no one knows but or even he does,

how the mysterious plants catch their prey. these carnivores all employed very different strategies. sorry, seni a for example, sets a pitfall trap. yeah. on the plan. so creates nectar here at the edge of the end here at the mouth, so to speak. next style associated with anecdotal and the nectar attracts, the insects inside the land. last start leaking are quite enthusiastic about it, like some more and more and more. then the plant emits a gas which makes the insect a little bit dizzy, less the intake. and so p c and the 2, they continue to look the nectar and, but they're a little harrison with choose which are directly downwards. that means it's easy to go down by defining backup is difficult, almost impossible for the flies mindful and cool. they've done it yet. and at some point they just fall in and are guns,

but it's amazing that the behind has evolved so cleverly at such a bloom 1st. so the insects come to palm and a 10 belief. and then when the blossom and with their half of a farms 200 feet on the insects 2 or 3 weeks later, for additional no trails veda only doubts who's that position now? and so the common defense, these also known as tropical picture plants, use pitfall traps as well. sweet nectar on the smooth pitcher rim attracts the insects which then fall into a liquid containing digestive enzymes where they drowned and are digested. some plants have even develop letters to learn amps, for example, into their deadly trap. other carnivores use, so called glue traps. yes, and you see it fine. so now we're here with the sun. new plant instead catches insects by attracting them to it's due to the sun. do refers to the adhesive droplets that glisten in the sun. now, the insects then sli onto them how they smell interesting. but once they're on it,

they gets stuck to the adhesive droplets. these tend to goes then push the insect to the middle of the leon, just intake out to a block. sometimes the leaf and crows around the insect, and enzymes start digesting the trend. cray, on the phone to avoid it so that that one better word also catches small insects with a sticky liquid on its leaves. and the more prey it absorbs, the more it grows and blossoms the best mailing carnivores, b. c, is goofiness, fly trap. it closes its catching petals around the pray originating from the us east coast. even charles darwin was fascinated with this plants. dead leaf snapped traps. so shy that the plants are creatures nectar and its traps. and there are small contact chairs inside. he has been defeating, i'm, when the flies look the nectar, they automatically activate these contact chairs,

not mac, suggest the plans. the 1st time it happens, i the plan registers agency and the 2nd time the plan sense is that there must be something in there stealing gets nectar crime. so it's that shot, i'm eyes that kind of ask. i don't, i feel very small prey like and can still climb out to see your competition, newman, but a fat house. why can't some of the plans in the, on a lose least, as i said now the plan performs and analysis is what i called protein rich are not enough feed out or is this? if not, it will open up overnight till the prey hours to spin into my hours per sheet, and if it is protein rich and then the plant begins to digest it in the act of household and in the put on some carnivorous plants are an amazing example of some of nature's most sophisticated techniques now onto the plants that humans eat according to a study by the world i can nomics for him. the number of people living on

a plan size died is decreasing, especially in highly population countries like india and china. on the other hand, in gemini and other western countries, the number of people giving up meat is on the rise. some people explained the shift by claiming that plant based on so healthy it. but is that really true? a giant without any or dairy products. some would call it mountain nutrition and others completely healthy. lots of people have an opinion, but if you have all the data on the nutritional scientist democracy, cather has been researching client based nutrition for 25 years. keller, who is reagan, says that a vegan diet is in itself neither healthy nor unhealthy. the gun comes here because of making died can be very healthy. if it's done right to die, you can also eat a very, very unhealthy vegan diet as cost a mix died is better than

a bad reading diet. but very often, it's the other way around. the beacons put more thought into their food. they are better informed and to make more wholesome food choices as well. how many studies over the years have shown that too much meat, especially processed meat, is bad for your health. it's also been shown that a diet containing plant based foods as healthy or at university hospital in van. we meet the body. the nutritionist is a senior physician and professor of nutrition and metabolism at the university of bound. in her daily work at the hospital. she notices time and time again. the positive effects of a vegan diet was adult while music in the very apparent and people's blood sugar levels. it's a woman this left with a much better profile is when people increase the amount of fiber, the eat fish,

the nordics falls that all that comes automatically when you eat a healthy vegan diet on the nod and you can definitely see the positive effects on collector all levels that come with who's not had a for safety fee bid, click official plan. secondary compounds play an important role. they come from vegetables, fruits, legumes, or nuts, and give plan based fluids, their color. they have a positive effect on health their anti inflammatory antioxidant, and can even reduce the risk of cancer. a plant based diet also provides other valuable substances. a safe, not ex faucet, a or dietary fibers have a great a fact with these they positively influence the micro biome dobs for the whole. in general, the quality of carbohydrates is much better if you eat chick peas and lagoons or nuts with valuable fatty acids on slack, fully fed to,

to or hayes. but what about eating up here? the vegan diet? the nutrition expert is reserved in her response. there's always the risk of a nutritional deficit, especially when it comes to vitamin b 12. it's needed for cell division and blood formation. and it's pretty much only found in animal products. in a strictly, fagan died. b 12 has to be supplemented in order to avoid the deficiency. in addition to b 12, there can also be deficits in calcium and omega 3 fatty acids, showing the trough make what color is always the question of how well we absorb a nutrient within the natural. what is the bio availability of these nutrients? a ha ashton's you have to be pretty knowledgeable about that. what contains, what, how do you combine food and how can you prepare the meal to make iron? i think it's linear, more available specific bodies. what about omitting gary products?

the health benefits are unclear, cottage cheese, for example, often contains large quantities of fact, what emitting them removes unimportant source of nutrients like calcium and iodine . studies provide evidence of reduced bone density and begins. but in the long term of the can die, i can have a positive influence on our health, for example, by reducing the risk of cardiovascular disease and type 2 diabetes. and there are indications that the risk of cancer might be reduced as well. for example, colon cancer, physicals and student need side of the, the files i need. the big studies definitely indicates the same thing that it reduces the risk of diabetes. you know, i've seen it over and over again in cross sectional studies and in smaller cohort studies. so there's a strong indication of a causal relationship, doc, i invite style stuff. so. so what does this cost cause i interviewed with them?

this is on the switch. medical expert says that eating a vegan diet requires a large amount of nutritional knowledge falls less hazel. that same degree at a quote, integrating plant base foods in your diet always makes good sense of the law digital data, shamefully back law. but the data doesn't show that it has to be a purely vision diet to read the benefit was like all see a note, but then you can nutrition as possible and can have a positive influence on your health. but it's not the only healthy way of eating the something that's perhaps even more controversial is the consumption of genetically modified crops. nearly 20 years ago, the n t much them also became the world's best genetically modified organisms to be marketed for consumption box. it didn't appeal to consumers in the us and cost because they were afraid of using genetically modified food. it has to be pulled

from the markets, but efforts to genetically optimize tomatoes, continue all these tomatoes lip deceptively normal. but some of them have magical powers. they've been edited to produce victim indeed . scientist hate these plans will help to fight is very wide spread like a victim indeed. and humans, one of the world's major health problems research team and you k genetically manipulated the tomatoes with tiny genetics. this is cool, chris, but cats 9. you can see here in the future while we grow up the wall, top tomato, which is not just as motto. and so our basement, each motto in parallel to the call really is how that differs within is that good thing is in tomato we didn't see any you loss or gross defects for those. so i, this is most close, and it just takes like tomatoes to make these tomatoes,

the scientists fuse the domestic scissors and change the molecule that tomatoes already have. previous mindy 3, a close relative victim. indeed. prove it. 20 is actually a building block, a victim. indeed, over time and the 3 to be exact, that's what up what he needs. normally an enzyme, blue color will occur in the tomato yourselves, would use the private to men's d to produce another molecule collateral but the genetics is stop the enzyme in its tracks. that means business as usual for private. mindy 3 permits men. d 3 cannot be used to build victim. indeed. ready when private men d 3 is hit by the sun's rays, it's magically transformed into victim. indeed 3,

that's the one we need to stay healthy. the modified victim, indeed tomato plants work just like the regular relatives. that's what the research is. claim. the seeds which carry the genetics seem to be photo and should go on to produce more plants with the fits meant in the. ready each gene edited fruit has around 2 micrograms of victim, indeed inside it, between 2 and a half and 7 of these tomatoes daily would provide us with the amount recommended by w. h. of the good news is to mazda is a popular in 2021. 189000000 metric tons with produced globally mold and sugar, but not as williams, but not everybody's open to genetic deals to the food. in fact, how for the public think it's on the safe. that's what the pew research center found when they asked people in 20 countries between the years 2019 and 2020

the way to richmond d. tomatoes was produced with the genetic says as though it's close to, to nature, then you might think that's what the scientists claim. those mutations are called naturally equivalent. that's maybe it could happen in nature. the natural process. i think that's the beauty of searching either thing you don't bring any for an james in the to month regina them. so they are the that is has been fixed in the some authors. you know, there's no other things can happen in those tomato lines. need to match the nines and now being tested in the field trials to see if they have any growth defects. and if they haven't equipment harvest, they're also being tested on humans to see if they can absorb the victim. indeed, if need to also succeed, they might play a role in fighting. the lack of victim indeed was wide. a basement deficiency is a big house problem globally, and approximately 1000000 people worldwide stuff us from basement the insufficiency

measuring and developing countries. so they're not developing countries. so the problem is we have very limited food source of basement to especially placement. these rate only a few foods have comes to control amounts if it's meant the inside. for example, fish an eggs the skin canals type adjacent amount of victim indeed itself. but i need to get some of some lights and it's hard to get sufficient amounts to determine from the source of the name. the victim indeed is vital for many, for the functions that helps the body of so calcium and phosphate essential for bi and strength. strong bones and necessary to support the weights of our in bodies and to move to run on surround without enough victim. indeed,

funds become berto and break much more easily. deficiency and victim indeed has also been linked to a number of illnesses including depression. now the scientist typed these tomatoes could help a number of people people were stuck committed skiing with how problem of, of self easily be lights which is essential to produces a, sorry, sufficient d, y human. so that's why they're thinking africa also um is, has the relative of the hype isn't the deficiency of rates in their population and researches and looking at different ways to use a genetic editing technique to possibly engineers and tomatoes also existing in other. so the next just crops and such as peta for, to show an upper james. so does the best suppose of also a post both to be either said was accumulate to the amounts of pro vision and these

rate that's also the work of the car in a moment. the tomato still need to pause clinical trials and off to it. there's no guarantee that there's some 1000000000 people that can victim indeed would eat them . but if the tomatoes succeed, the hoop is fewer people would suffer from victim indeed deficiency. if i was what is read, why do you have a science question? send it to us in a video text or voice message. if we don't see it on the show, we'll send you a little surprised as a thank you on just task this week, august, and comes from a how many below yellow from sierra leone. the how does noise effect plants the,

the world has been getting louder for decades and it's not just humans and animals that suffer from the increasing noise levels. so do plans. they don't have years, but they can still receive sound. waves. primes produce messenger substances that they use to transmit sensory stimuli to their organs by a network of these things. in 6 use the same process, these beat their wings at the very specific frequencies to stimulate the release of palm and in certain plans. this evening, primrose responds to buzzing sounds. within minutes of detecting these are months, the sugar content and its nectar increases by up to 20 percent. the

studies have shown that fail grass can even distinguish between certain sounds and tones. whenever the plants sense the predator, it secreted toxins to protect itself. but the vibrations of the wind didn't trigger the defense mechanism. experiments have shown that sounds can even change the activity of genes after 5 days of continuous noise. the activity of several genes change in the cell, chris and the activity of photosynthesis decreased. the noise also affects plants by animals because it scares away birds and pollinating insect researches in the us studies of long term consequences. over a period of 15 years, they looked at the vegetation in quiet regions in places where

a noise source had been removed. and in areas that had been subjected to the constant noise of natural gas mining. before the study began, the comparison of the 3 areas showed that constant noise decreased the biodiversity of vegetation. in the loud areas, a certain pine had diminished by 75 percent. juniper trees need jays to spread their seats for reproduction. but the jays didn't return to areas after the noise source had been removed. other species had grown in place of the universe, which shows that noise can have long term effects on plants. and now for something completely different. when lions root all, they mounting the 2 or 3. but that doesn't always make it easy to determine the location. students at the design, university of technology have developed

a digital acoustic device that can locate loud animals up to 500 meters away and they tested it on housing rolls. the this sound has given us chills since the dawn of time, the wolf. how is also an important sound for the game keepers who monitor them but keeping a close watch over them around the clock is impossible. a trip to the outs where the game cheaper is out with a young entrepreneur named olivia staley. staley wants to help gain keepers monitor wolds more efficiently with the help of artificial intelligence and a special device like a wildlife and box it can automatically locate,

will not buy their housing food. that housing the wolves can be heard for more than 3 kilometers away. so we can cover large areas completely cheaply and automatically when a how it has been detected. it sends a message to the game keeper in real time, the sort to the device that's daily developed can locate a wolf. how to an accuracy of 500 meters in my mind from many animal monitoring methods require human made tools and select photo traps. space for what was in particular can sometimes allude us exist. they remember where the photo traps are, because they don't like the flash or the sounds they make so. so they go around the photo traps on with our method before we want to trick the woods by engaging in their methods of communication. and that way we can collect the data and photo feet and on the same sol, off the some and then, and we can actually cover this whole area here on. so it could be complex at the

switch, federal institute of technology and most on stanley developed a device with 3 other students. they set up 30 devices in the area for their research. noah schmidt is the company's technical manager. this is you should, this is what we call the smart mike. it's a device based on the raspberry pi, a mini computer, if they're still in the computer, it has gps and cellular reception, which is used to transmit the audio, or that i would just throw books on the video. the sounds are sent to the servers and the audio files are converted into images. ringback artificial intelligence evaluates the images and identifies whether or not it's a wolf cell who, if a wolf is located, a game keeper gets a notification immediately. according to a game keeper, michael bonds at the devices could be used to prevent wolf attacks in monitor pac formation. or the device could also assist with shootings

through let them know the sooner they should start the pack is a special protection status. it up to the device, it tells you where the pack is for you and you can determine if a female is with the pack boone and seeing which direction they're moving to home. and i don't know. and so if you know with the pack is, you know, you have to be careful about shooting loan wolves around there, and the stream was what it was supposed to meet them and know it's really helpful with a specific fee load. the certificate and staley says several swiss regions are interested in the product as, as the world wildlife fund it's use doesn't have to be limited to europe. i may have to commit to submit this night and i'm afraid of ultimately we discovered that this works for more than just the walls. we don't pay this push. we were in south africa in the spring and tested it on elephants, lions, and hi eunice. and it working to me a bottom being told to me, i'm not saying that it's an artificial intelligence, could make handling wild animals much easier in the future.

that was it for tomorrow. and today dw science program will have more exciting stories next week. pennsylvania state curious by the
