people have to say, that's why we listen. we chose every weekend on d w. the we cons exactly say that we treat the people on the world with respect we're 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 or today due to we use science magazine. most people don't get 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 or be need to around $800.00 sounds bases are kind of varies. they can catch flies and can even eat small pieces of meat and they display and lots variety of different strategies for catching pray. carnivorous plants everywhere you look 36 years ago, then file kind of founded the carnivorous plant nursery in the southwestern town, a fine time now the largest in germany. and no one knows better than 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 plants to greet

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 admits 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 of the 2 x which are directly downwards. that means it's easy to go down, but it's finding backup is difficult, almost impossible for the flies mindful and cool. they've done it yearly, and at some point they just fall in and are gone. and it's amazing that the behind has evolved so cleverly at 6 and bigger. talk this one. ok, i'll push there are countless species of the stars, the need of gina's in many different colors. these flowers even use its blossoms to catch prey. this particular strategy is that they bloom 1st. so the insects come to

palm and a 10 boys. and then when the blossom and weather after they forms 200 feet on the insects 2 or 3 weeks later, for additional no trails veda, only doubts. who is that position now? and so becoming the tendencies also known as tropical picture plants, use pitfall traps as well. sweet nectar on the smooth picture 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 lower ends, 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 its due until the sun do refers to the adhesive droplets that glisten in the sun. now the insects then fly onto them out. they smell interesting. but once they're on it, they gets stuck to the adhesive droplets. these tend to goes and push the insect to

the middle of the lee, understand how to apply. and sometimes the leaf and crows around the insect, and enzymes start digesting the tract. pray on the funding to void it. so if at 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 known carnivores pcs is the dana's fly trap. it closes its catching petals around the pray originating from the us east coast. even charles darwin was fascinated with this plants. deadly snapped trap. too shy to look the creature nectar and it's travis, that's it. and there are small contact chairs inside the bend. if you can, 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 senses that there must be something in there stealing gets nectar climb. so it snapshot eyes that kind of house. they don't, i so very small prey like and can still climb out to see your competition name. but a fat house by can some of the plans and the lose least as i said now the plan performs and analysis is what i called protein retro now to event. not be the house or is this? if not, it will open up overnight to the pray hours to spin into my hours for sheet, and if it is protein rich and then the plant begins to digest it in the stuff of household and in the plaza. 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 economic for him, the number of people living on a plans face 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 prompt phase diet, so healthy it. but is that really true? a diet without any meat 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 and the nutritional scientist model is cather has been researching client base nutrition for 25 years. keller, who is vegan, says that a vegan died is in itself. neither healthy nor unhealthy. begun comes in because of thinking died can be very healthy if it's done right to die. you can also eat a very, very unhealthy vegan diet cost a mix. diet 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 swell. how many studies over the years have shown that too much me, especially processed meat is bad for your health. it's also being shown that a diet containing plan based foods is healthy or universe at the hospital in van. we meet the bobby, the nutritionist is a senior physician and professor of nutrition and metabolism at the university of bout in her daily work at the hospital. she notices time and time again, the positive effects of a vegan diet. so that when we use the very apparent in people's blood sugar levels of moment did with a much better profile, is when people increase the amount of fiber they eat fish, the nordics falls at all. that comes automatically when you eat a healthy vegan diet, like on the nod,

and you can definitely see the positive effects on cluster all levels that come with the who's not had a full safety fee bid. click official plan secondary compounds play an important role. they come from vegetables, fruits like you are nuts and gift plaid based fluids, their color. they have a positive effect on health, their anti inflammatory antioxidant, and could even reduce the risk of cancer. a plant based diet also provides other valuable substances. a safe, not ex fawcett, a or dietary fibers have a great a factory feast. they positively influenced the micro biome that 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 diet. 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 during mega 3 fatty acids is showing that's all to make what color is always the question of how well we absorb a nutrient towards the natural. what is the bioavailability of these do trans hall actions? you have to be pretty knowledgeable about that. what contains, what, how do you combine fluids and how can you prepare the meal to make iron think it's lenae a more available best associated bodies. what about omitting gary products? the health benefits on clear cut cheese for example,

often contains large quantities of fat. but to meeting them removes an important 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 fight 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 on them. and so there's a strong indication of a causal relationship, doc, i invite style stuff so, so what does this cost cause it can be done? this is on the switch medical expert says that eating a vegan diet requires

a large amount of nutritional knowledge falls less hazel. that's integrated. a quote integrating plant base foods in your diet always makes good sense of the lock, diesel duty. she feedback law about the data, does it show that it has to be a purely vision diet to read the benefit? let's make on say a note with in region nutrition is 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 tomorrow also became the world's 1st domestic, a modified organism to be marketed for consumption boss. it didn't appeal to consumers in the us and cost because they were afraid of eating genetically modified food. it has to be pulled from the markets,

but efforts to genetically optimize tomatoes, continue these to monetize and up to step tiffany normal. but homeless and have magical powers, they've been edited to produce victim indeed, scientist hope 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 u. k. genetically manipulated the tomatoes with tiny genetic scissors, cool, crisp across 9. you can see here in a few trial week row of the tomato, which is now just as motto, and so our basements, each motto in parallel to the call really is how that differs. within is that this thing is in tomato we didn't see any of and you loss or gross defax for those. so i just as most clothes and it just takes like tomatoes to make these tomatoes, the scientists fuse the domestic scissors and change them on the cuba tomatoes

already have private men d 3, a close relative victim. indeed. pivot 20 is actually a building block, a victim in d over to me in d 3 to be exact. that's what up what he needs normally an enzyme, blue color will occur in the tomato yourselves, which used to prove it to me in the to produce another molecule collateral but the genetic says is stop the enzyme in its tracks. that means business as usual for prey, richmond d 3 permits, men. d 3 can not be used to build victim indeed or. ready ready when private some and the 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 seed switch 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 could provide us with the amount recommended by w. h. of the good news is to mazda is a popular in 2021. 189000000 metric tons were 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 nature,

then you might think that's what the scientists claim. those mutations are called naturally equivalent. that's makes, it could happen in nature. the natural process. i think that's the beauty of searching. i just thing you don't bring any for an james in the to month regina them so. 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. new to my to 9 to 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 like a victim. indeed, worldwide, 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, the, especially basement these re early a few foods have consequential amounts. if it's mindy inside, for example, fish and 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 these sources 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 strung 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 even a deficiency. and victim indeed has also been linked to

a number of illnesses including depression. now the scientists type 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 that would be africa also. um is, has a relatively high this empty deficiency rates in their population. and researches are 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 pep talk to so and objects. so those of us 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 hope is fewer people would suffer from victim. indeed, efficiency is always let us read. why do you have a science question? send it to us in a video text or voice message. if we don't do 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 upset to 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. plants produce messenger substances that they use to transport 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 common in certain plans. this evening, primrose responds to buzzing sounds. within minutes of detecting these are months, the sugar content and it's nectar increases by up to 20 percent. the studies have shown that fail. chris can even distinguish between certain sounds and tones. whenever the plan sensed, a 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 study the 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 junipers, which shows that noise can have long term effects on plants, the and now for something completely different. when lions rule, they mocking 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 on housing roles 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. wildlife, a wildlife unbox can automatically locate, will not buy their housing food. the housing of wolves can be heard from more than

3 kilometers away. so we can cover large areas completely cheaply and automatically when the, 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's how to an accuracy of 500 meters. in my mind, from many animal monitoring methods require human made tools like photo traps space for the 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 sort of open them on the same sol office on and then, and we can actually cover this whole area here on that could be optic at the switch. federal institute of technology and most on stanley developed

a device with 3 other students. they've set up 30 devices in the area for their research. noah schmidt is the company's technical manager. this is, 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 bit. 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. to the device could also assist with shootings

through let them know the sooner they should start the pack is a special protection status to that the device, it tells you where the pack is for you and you can determine if a female is woods, the pack wound 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 the earliest one was but it was supposed to meet someone else. it's really helpful with a specific fee low through. 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. may i ask who i'm going to submit this newton? i'm afraid of, of we discovered that this works for more than just the was, you don't pay tish. we were in south africa in the spring and tested it on elephants. the 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

specialties. so it's little unusual sized with luxury and flavored with the touch of i'm kind of mary. excellent. all the just setting up your up to save your own coming up on dw, this suddenly a team interest in there, which is great for us fashion made indeed luxurious fabrics and vibrant color
