the hello and welcome to tomorrow. today, d, w, science magazine, most people don't get enough credits. 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 oh, be need to around $800.00 tons. bases are kind of varies. they can catch flies and can even eat small pieces of meat and they display and lots of 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 south western 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 or for example, such a pitfall trap yeah. on the plan. so for each nectar here at the edge of the end here at the mouth, so to speak. next style associated with then mcdonald and then nectar. attracts the insects inside the land. last start leaking are quite enthusiastic about it. like something more and more and more. then the plant i'm, it's a gas on which makes the insect a little bit dizzy, less the intake. and so piece you in the to continue to look the nectar and, but there are little harrison the 2 makes which are directly downwards. that means it's easy to go down, but slamming back up 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 6 and bigger talk this

one on calculus. or there are countless species of the star seeming 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 den boy, 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 the common attendees 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 used so called glue traps.

yes, and it's 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. 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 the sometimes the leaf and crows around the insect, and enzymes start digesting the trend prey on the phone to avoid it. so if at that one, butter 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, bc's is cardenas. why trap? it closes its catching pedals around the prey. originating from the us east coast, even charles darwin was fascinated with this plants. deadly snap trapped.

so shy that looks fine, secrete nectar, and its traps. and there are small contact hairs inside the a one vendor leaving i'm when the flies look the nectar, they automatically activate these contact chairs, not mac, suggest the plans the 1st time it happens, the plan registers agency. in the 2nd time, the plan senses that there must be something in there stealing gets nectar climb. so it's not shot as a kind of house could identify. so very small prey like ads can still climb out to see your competition, newman, but a fat house. why? can't some of the plans and the lose least as i said now the plan performs and analysis is what i called protein retro. not enough feed out or is this? if not, it will open up overnight to list the pray hours to spend and to 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 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 economic forum, the number of people living on a plant 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 plant phase diet, so healthy it but it's not really true. a diet without any need or gary product. some with code mt. 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 base nutrition for 25 years. keller,

who is vague and says that a vegan diet is in itself neither healthy nor unhealthy, begun comes in a vacant guide, can be very healthy. if it's done right to die, you can also eat a very, very unhealthy the gym diet. as close a mix died is better than a bad vegan diet. well, 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 meat, especially processed meat is bad for your health. it's also being shown that a diet containing plan based foods is healthy or at university hospital in band we meet via 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 musa, very apparent in people's blood sugar levels. a woman with a much better profile is when people increase the amount of fiber they eat, their fish, the not it falls at all. that comes automatically when you eat a healthy vegan diet, like on the and not. and you can definitely see the positive effects on collector. all levels coming to of course not had a $450.00 fee bid. click official plan secondary compounds play an important role. they come from vegetables. fruits like you are nuts and give plaque based fluids to their color. they have positive effects 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 fact is they positively influenced the micro biome that 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 the o hayes. but what about eating a purely 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 vague and 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. so in the truck make what color is always the question of how well we absorb a nutrients within the natural. what is the bioavailability of these do trans hall

ashton's 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 specific bodies. what about omitting gary products? the health benefits on clear cotton 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 in regions. but in the long term of you 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 the type of the, the file 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. i'm. 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 medic. so expert says that eating a vegan diet requires a large amount of nutritional knowledge falls less hazel. that's integrated. quote, integrating plant base foods in your diet always makes good sense. of them off the show, did she see that law all the data? does it show that it has to be a purely beacon diet to read the benefit was like on see and then what then you can 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 to most of it became the world 1st, genetically modified organisms to be marketed for consumption boss. it didn't appeal to consumers in the us and costs 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 some of them have magical powers. they've been edited to produce victim indeed, scientist hate. these plans will help to fight, to very wide spread like a victim indeed. and humans, one of the world's major health problems, the 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 waltz motto, which is now just as motto, and so our basements,

each motto in parallel to the call really is how the difference within this, that goose thing is in tomato. we didn't see any. you loss or growth defects for those. so i just as most of calls and it just takes like tomatoes to make these tomatoes. the scientist fuse the gymnastics is, has been changed to monte tools at tomatoes, already have prove it to me in d. 3, a close relative victim. indeed. prove it. 20 is actually a building block, a victim in d over to me in the 3 to be exact. that's what up what he needs. normally an enzyme, blue color will occur in the tomato yourselves. what do you use to prove it to me in the, to produce another molecule, collectible? but the genetic says is stopped the enzyme in its tracks. that means business as usual for private mindy 3 permits. mindy 3 can not be

used to build victim indeed, or. ready when private and then 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 to monte pumps work just like the regular relatives. that's what the result just came the seeds which carry the genetics seem to be photo and should go on to produce more plans with the fits mindy, and the 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 o. the good news is to monitors of popular in 2021, 189000000 metric tons with produced globally molding sugar, but not as williams, but not everybody's open to domestic deals, to 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 the richmond d. tomatoes was produced with the genetic says as though it's close to tonight. so then you might think that's what the scientists claim. those mutations are called naturally equivalent. that makes, it could happen in nature. the nature of process. i think that's the beauty of searching. i just thing you don't bring any for james in the to month regina them. so they are that that is has been fixed in the some of those. 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 they need to actually succeed, they might play a role in fighting the lack of victim. indeed, worldwide, a visually deficiency is a big house problem globally. and approximately 1000000 people worldwide stuff us from basement, the insufficiency no mention in developing countries or they're not developing countries. so the problem is we have very limited food source of vision to is special investment. these rate only a few foods have consequential amounts. if it's a minute the inside for example, fish and eggs. the skin can also produce an 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 binding strength strung bones and necessary to support the weight of our employees and to move to run on surround without enough victim into the funds to come portal and break much more anthony 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 skin with how problem of, of self easily be light which is essential to produces the size of richmond d by human. so that's why they're thinking africa also um is, has a relatively high but some deficiency rates and then their population and reset chosen, looking at different ways to use the genetic editing technique to possibly engineered

in tomatoes, also existing in august. so the next just crops such as pep talk to so and over again. so those of us suppose of also a post both to be i did, said was accumulated amounts of for pro basement these rate, that's also in a walkabout carry on a moment, tomato still need to pass clinical trials and off to it, there's no guarantee that the some 1000000000 people that can victim indeed would eat them. but at the to most of succeed the who pittsfield people would suffer from victim indeed deficiency. if i would let is read, why do you have a science question? send it to us in a video text or voice message. if we onto it on the show, we'll send you a little surprise as the thank you. hold on just task this

week, august, and comes from a how much below yellow from sierra leone. the how does no is effect plans 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 weeks times produced messenger substances that they use to transfer the sensory stimuli to their organs by a network of these things. in 6 use the same process. these beats 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 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 sensitive predator gets a created 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 sale, chris and the activity of photosynthesis decreased. the noise also affects plants by animals because it scares away birds and pollinating insect.

researchers in the us study the long term consequences. over a period of 15 years. they looked at the vegetation and 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, 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 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 gatekeepers 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 of 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. this was 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 full moves 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 thought the some. and then we can actually cover this whole area here on. so it could be a 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. yes, because 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. to 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 woods the pack wound and seeing which direction they're moving to home . and i don't know if it's so if you know where the pack is, you know, you have to be careful about shooting lone wolves around there and the stream was what it was supposed to meet them and know it's really helpful with associated fee low through citizens from 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 have to commit this nickname, affordable. we discovered that this works for more than just the walls and 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 from continue change of the from the 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

a pulse of the beginning of a story that takes us along for the ride. it's about the perspectives,
