the top costs for everyone who wants to know more about the topics that concern us about this story is beyond the headline world in progress. the w cost cost we cons exactly say that we treat the world with respect we are constantly exploring fonts at every opportunity and we try to optimize them through breeding engineers like modification. the shots are extremely sensitive to external factors like noise, for example, the hello and welcome to tamara today d w, 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 o. b need to around 800 sounds, bases all kinds of various. they can catch flies and can even eat small pieces of meat and they display a notch variety of different strategies for catching prey. 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 or 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 must intake. and so piece you and the to, to continue to look the nectar and, but there are a little harrison 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 click on it yet. and at some point they just fall in and are guns. but it's amazing that the behind has evolved so cleverly a switch and bigger talk this one. ok, i'll push there. countless species of the star city of gina's in many different colors. these flowers even use its blossoms to catch prey. this particular

strategy is that's a bloom 1st, so the insects come to palm and 8, then boy. and then when the blossom and whether after they farms 200 feet on the insects 2 or 3 weeks later, for additional no trails veda only doubts. who is that? position now and so become an attendees, also known as tropical pitcher 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 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. now the insects then fly onto them out. they smell interesting

. but once they're on it, they get stuck to the adhesive droplets. these tend to goes and push the insect to the middle of the lee. understand out so a lot, sometimes the leaf and crows around the insect and enzyme struck digesting the tract. pray 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 the fetus fly 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 here. when bending you can, i'm, when the flies look the nectar and they automatically activate these contact cares

. last, mac suggest the plans, the 1st time it happens on the plan. registers items in the 2nd time the plan sense is that there must be something in there stealing gets nectar crime. so it's that shot as a kind of house. they don't, i so 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 and the lose least, as i said now the plan performs and analysis is what i called protein, which are not enough to house. or is this? if not, it will open up overnight to the pray hours to spin into my house 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 forum,

the number of people living on a plan phase died is decreasing, especially in highly populated 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 it's not really true a diet without any or gary product. some would code mountain nutrition and others completely healthy. lots of people have an opinion, but if you have all the data on the nutritional scientist, tomatoes 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. 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 me, especially processed meat is bad for your health. it's also being shown that a diet containing plan based foods is healthier 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. what did we as a much better profile is when people increase the amount of fiber they eat or fish,

the narcotics for us 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 collector. all levels coming through who's 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 gift plaid based fluids, their color, they have positive effects 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 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 phones slacks slowly fed to the

o 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 product. in a strictly, fagan died. b 12 has to be supplemented in order to avoid a deficiency. in addition to b 12, there can also be deficits in calcium and omega 3 fatty acids showing that crosby, what color is always the question of how well we absorb a nutrient towards the natural. what is the bio availability of these nutrients? the hall actions you have to be pretty knowledgeable about that. what contains, what, how do you combine fluid? and how can you prepare the meal to make iron think it's linear, more available specific bodies. what about omitting dairy products?

the health benefits aren't 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, coleman cancer is it was installed in the side of the, the pilot. i need the big studies definitely indicates the same thing that it reduces the risk of diabetes. i've seen it over and over again in cross sectional studies and then smaller cohort studies. so there's a strong indication of a causal relationship, doc, i invite styles, does so. so what does this cost cause i interviewed with them. it says this was

medical expert says that eating a vegan diet requires a large amount of nutritional knowledge. while it's less hazel, that's integrated, a quote, integrating plant based foods in your diet always makes good sense of the law, visual data, she feedback 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 energy much tomorrow, so it became the world's best genetically modified organisms to be marketed for consumption. bought. it didn't appeal to consumers in the us in 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 lip deceptively normal. but homeless and have magical powers. they've been edited to produce victim indeed, scientist hate. these plans will help to fight a 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 genetics. this is cool, crisp, across 9. you can see here in the future while we grow on the wall, top tomato, which is not just as small so and so our basement each month. so in parallel to the call really is how the difference we did is that this thing is in tomato. we didn't see any you loss or bruce defects for those. so i, this is most close, and it just takes like tomatoes to make these, to month,

as the scientists use the domestic scissors and change them only 2 of the tomatoes already have previous. mindy 3, a close relative for victim. indeed. pivot. 20 is actually a building block, a victim. indeed. over 2 men, d 3 to be exact. that's what our body needs. normally an enzyme called a worker in the tomato yourselves would use the private to men's d to produce another molecule collateral but the genetics is to stop the enzyme in its tracks. that means business as usual for private. mindy 3 permits, men. d 3 cannot be used to build wichmann d or. 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 result just came. the seeds which carry the genetics seem to be photo and should go on to produce more plants with the fits mindy 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 domestic 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 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's means 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 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 much in 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 like a victim in the world 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 another problem is we have very limited foot source of basement the especially basement these rate only a few foods have consequential amounts of it to me in 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 in bodies and to move to run on surround without enough victim. indeed,

funds become portal 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 with duck committed, us getting with how problem of, of solve easy be light, which is essential to produces the size of richmond d, y human. so that's why they would think of africa also. um is, has a relatively high bas, empty deficiency, the rates in the, in their population and reset chairs and looking at different ways to use the genetic editing technique to possibly engineered in tomatoes. also existing in other to the next just crops such as pep talk to so an over james. so those of us suppose of also a post both to be either as it was accumulated to the amounts of pro vision and

these rate that's also to walk about carry on a moment. 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 to most of succeed, the hope is fewer people would suffer from victim indeed deficiency. if i would 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, i will send you a little surprise as a thank you. hold on just task this week, august, and comes from a how much below yellow from sierra leone. the, how does noise affect 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 bessengers substances that they use the transcripts, sensory stimuli to their organs via 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 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 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 allowed areas, a certain time 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 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 gatekeeper 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 wild life and box it 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 house 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 with methods require human maids 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 people. 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 could be optic 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 many computer. yes, because they're still in the computer. it has gps and cellular reception, which is used to transmit the audio. well that i would do the 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 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 this boom was what it was supposed to meet someone else. it's really helpful with a specific fee load. the certificate needs to be 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? make them affordable. we discovered that this works for more than just the walls. we 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 from last name to the, from the artificial intelligence could make handling wild animals much easier in
