do you correspondent susumu hard. to believe. that all the various flavors of the exotic are using i am a challenge for you all of the region and the real. food of fusion and far. from street food the fire star restaurant tasty taipei start september 1st d.w. . future into tomorrow today the science show on d w coming up. we continue our journey in the footsteps of alexander from home bought this week we visit members of the art show up people in the amazon rain forest. the rain forest is a source of medicinal plants researchers are trying to identify their active ingredients

and find new ones is. another trend in medicine artificial intelligence that can help diagnose diseases but 1st a look back in time. you noted of in she was an amazing anatomist who did about 30 cadavers and created exquisite drawings of what he found the discovery of x. rays allow doctors to look inside our living bodies without cutting us open. ultrasound for the change diagnostic methods now scans of various kinds connected to computers are generating lots of data so much that it's getting hard for radiologists to process alone artificial intelligence can help. here at s n university hospital about a 1000 patients have radiological exams every day. we're giving you a small dose of contra. stage and. this results in countless images that have to be

evaluated for that doctors depend on high powered computers and increasingly on artificial intelligence you're walking on guts or we need tools because there's simply more data. photographed one hand and that wasn't much data of course it's exploded today from organs actually the computer doesn't even look at the images it looks at all the ones and zeros that make up the images. and the computers can infer a lot more information from high resolution m.r.i. and c.t. images than humans can to recognize the abnormal patterns indicate disease in the fine gradations of great tones radiologists need years of training and the most concentration here's how the human brain accomplishes this task are billions of nerve cells are constantly forming new connections in the brain and breaking down others this is how we learn and how patterns are impressed upon our minds so that

we recognize them if. the problem is that the more data the brain has to process the faster it tires out and the polls will forgive if you look at thousands of images and even as a non radiologist you can guess that a finding will slip by you because you are tired that doesn't happen to a computer and we have extremely large quantities of data to analyze it well you need computer power. or computer paul after all computer programs are superior to humans beings when it comes to recognizing patterns but 1st the computer needs a kind of basic training it's presented with a certain pattern then it compares all other patterns with this template and decides does the pattern match or not. programs that recognize patterns have been used in the field of radiology free.

years foresting now wants to deploy artificial intelligence to help detect damage to brain tissue. this is our guts and this our patient had an acute stroke under x. but sees that this c.t. here is not entirely normal this is a war that requires years of training or if we analyze the images with ai then it highlights this area showing that a stroke has occurred here with this weight radiologists who don't look at several strokes a day like we do you can at least use this as an aid. to submit whether they accept the suggestions is something they have to decide for themselves or so i'm in. charge of artificial intelligence or a.i. goes beyond mere pattern recognition the aim is to imitate the way the human brain works using software artificial neurons are connected with each other in layers and said with an algorithm a sequence of instructions. the task here is to recognize

a circle at 1st images of various shapes are fed into the system. during the learning phase a human tells the system whether it correctly recognize the image or not the system changes the connections between the artificial neurons accordingly. the ones that lead to the correct result get stronger those that led to the incorrect result get weaker that's how artificial intelligence learns is it you're seeing something here that no one else in the world can see only here it's an absolute wild fust. forcing and his team are trying to further improve the skills of their ai system. the scene the program is still in the learning phase. we're going to see much more years in human form what we have here is an earlier exam the current exam we see these white stripes that we didn't have here before it all so that's new to

see there's a radiologist i can see it very well now i can work through the entire finding from top to bottom you know yet but what sina does this help me by color coding the differences between before and after you know the newest changes a shown an orange to visualize it while the previous image is marked in blue. seen allays the old in your images exactly on top of each other and makes every difference visible for example whether a tumor has grown but that's not all. in the background the artificial intelligence system calls up similar images finding some treatment recommendations from medical databases and textbooks dr ai is much faster and more systematic than a human being could ever be this way it provides radiologists with crucial advice on diagnostics and treatment. i can look at different images of this disease that have been confirmed and compare them. then i also have the patients clinical

information as well as clinical information that's typical for this disease if you do something to present to learn successfully programs like ciena need clear exemplary images and diagnosis after all ai will only get smarter if doctors and programmers provide it with good days. since i don't think it makes any sense for me as a dog to best a mediocre. orphan i teach a person to take up doctoring as a hobby each of us should play in the champ. league of our own disciplines is the. forcing is convinced that in future more and more of the growing flood of data in radiology will be prescreened by dr ai decisions about diagnosis and treatments however will remain in the hands of human doctors for the time being.

on the one hand medicine is becoming ever more high tech and complex using ai virtual reality and robots. on the other hand many patients one therapies they consider a natural or authentic nature also provides of all materials for academic myths and if you in mexico has a question about that. what is nature based on a natural path like medicine. for one thing it's at the root of modern university and science based medicine. the majority of modern pharmaceuticals are derived from plants. plants to be used for medicinal purposes for files and of yes both. traditional healers use a range of leaves flowers fruits roots and bark. in some parts of

south america teammate with the bark of the said rio tree is used as a painkiller call rossa leaves combat headaches under parts of africa the box of the african cherry is used to treat a wide range of ailments. the world's tropical rain forests are rich in plants with known medical properties. a lot of research is going into identifying the active substances in them and into identifying other species that might feel substances of medicinal value. some substances used in certain systems of traditional medicine are. actually toxins but appear to have therapeutic effect if the dosage is right so quickly small. terms such as nature based on natural medicine can also denote something quite different namely to fair acutely the fact of exposure to nature or natural forces sunlight. fresh air. water

a german tradition of hydrotherapy named after the bust focuses on the stimulatory effects of cold water. of course diet has an impact on health as well. and then there's the traditional chinese medicine. the term natural medicine covers a wide range of traditions substances and therapies some of these are called complementary therapies where they're accepted by conventional science based medicine as possibly helpful to treat symptoms or side effects. of all plant families 12 in particular contain an amazing wealth of mr slow flounce the mowbray family is the single greatest source science is sussed out in whether mulberry leaves can lower blood sugar levels in diabetes patients. johnson the dr and family healed substances that could treat cancer and anticoagulants are found

in some members of the legume family. there are so many plants with medicinal potential research is underway to find out how and whether they work. it's knowledge that dates back thousands of years the healing effect of plants and herbs knowledge that was hugely important in the middle ages but then to some extent forgotten. many scientists are now developing a curiosity for these plants and medical practitioners are rediscovering their healing powers. german herbs expr. put comma knows the healing potential of domestic plants here she's gathering herbs for medicinal teas and some independents and the like that owns them birch leaves because they flush out the urinary system and black berry leaves have an anti-inflammatory effect in the mouth. all use all 3 to make an herbal blend it's like

a home pharmacy. to protect themselves against pasts and pathogens herbs often contain oils bitter substances and acids that kill germs like willows along with many other active ingredients their bark contains salicylic acid compounds at the end of the 1900 century chemists develop these substances into one of the most popular fever and pain relief medicines aspirin. more than a 1000 herbal medicinal products are licensed in germany and new ones are constantly being discovered around the world many are still not well understood and research are underway as hens it is trying to unlock their secrets he's investigating marshmallow root and cat's whiskers which contain substances that may help relieve coughs and urinary tract infections the researchers goal is to develop new drugs and improve available once the futa are the problem is the sheer

multitude of substances in these medicinal plants often we know the plant has an effect except that many times we tell it which of the countless substances is responsible or if that's what our research is about cracking this code so we can develop more effective medications but the comment if you don't support. sage is also an intriguing plant it's known to have a wound healing effect but there are over 50 potential active ingredients so which one is responsible for healing wounds researchers are trying to find answers using human skin. they treat them each with a single isolated substance from the sage plant the question is does this substance promote cell production because for a womb to heal new skin cells have to grow in that area. the samples are tested a few days later. it's

a detailed and time consuming morgue but the results could be significant. for them to be able to find it would be such a great breakthrough to identify which substances have the most positive wound healing effect pretty big especially for bedridden patients that are hard to treat hopefully our research will help us to develop new drugs. they haven't tested all the substances yet but they hope to find the active ingredient within a year or 2 and then develop a drug from it. research is further along for other medicinal plants. at the clinic in western germany treats patients every day with highly effective herbal drugs. the clinic uses more than 50 plant based medicines in the internal medicine department alone and that for 15 years now . supplementing conventional medicine with herbal remedies can offer big results.

like for nonspecific back pain and ailment many people suffer from because of nonspecific back pain can be greatly helped by using herbal medicine the biggest advantage of these horrible drugs is that they often cause fewer side effects significantly fewer that acim also plays a major role in treating respiratory diseases it can alleviate the symptoms which means less coughing less pain in the limbs and faster healing and there's no conventional alternative to this herbal remedy that's on a par in terms of side effects a lot so once again the defense team is. of course it's always important to speak to a doctor about the potential causes of an illness and the treatment plant self medicating with herbal remedies alone could be life threatening it's a danger that. is aware of her medicinal plants are considered safe but when she has a condition that doesn't respond quickly to an herbal treatment she consults

a doctor. called what is right why are. you going. to do have a science question that you've always wanted answered it we're happy to help out send it to us as a video text ovoid smell if we answer it on the show we'll send you a little surprise as a thank you can i just ask. you'll find as i do w dot com slash science or drop us a line at d w underscore site tech on facebook d w dot saw. the naturalist alexander from home but who explored large areas of south america rose about the healing properties of the rind of the cinchona tree which indigenous people use to treat a range of elements. later it's active and see malarial ingredients quinidine was identified. him gold was keen to understand the way the peoples of the region

lived their lives and then destroyed the world. in the latest episode of a series on his travels in the americas we had to ecuador and the legacy of the in ca's. meaning when we. go pick up. a stone fortress in southern ecuador built by the ancient in crowds at its center the so-called temple of the sun. is that the temple was arrested on a perfect ellipse we suspect that it was a place of worship on the same hill the kind yari people had prayed to their gods until they were conquered by the. incas simply converted the site and adapted the walls to the style typical of their capital cusco. get their name

with. in this way they left behind their own cultural imprint while preserving the original layout of. making it unique in the entire indian empire building. one has to admire the sense of precision and symmetry these people had rowed alexander for home both about the fortress of ink up erica. on the old in co road he visited one of the few preserved remains of the pre-columbian empires and by his time spanish colonial rule had already wiped out 90 percent of the indigenous population. but home board continued his explorations eager to study those people whose culture and way of life had remained completely untouched by the spanish conquest.

our expedition following in home bodes footsteps takes us to the western amazon basin at the border between ecuador and peru. in a single propeller plane we follow the course of the past us a river. deep into the territory of the people. you me well where you. will.

if you want to hunt you must respect the rainforest 6 and ozzfest the wren forests to provide the food if you are not respected that rain forests and the rain forests will never give you nothing. if. they are the guardians from the forest. leaves here for thousands of years sunday or in forests. these are home. life has nobody understands what the forest is than they are.

the amount of mighty who would be the waterfall is the home of our spirit out of tom. and the only moving him you know this sacred spot but it is where our ancestors arrived in this world from imo i'm a fan to them i hear they found protection and sound healthy to manifest. centuries after on boats american expedition that you are still live largely isolated from the outside world and preserve their own language customs and

traditions. before dawn we received by the head of the local community we joined in the dream interpretation ritual with which the actual are usually begin their day. now this is basically they are here. for you and we sometimes talk about our dreams from the previous night feeling as if he must but sometimes it's about special dreams that we call can order. go to meet with a normal sleeping as something different you know these are visions that we don't get during sleep or think they have a different significance than normal trains normal throwing. more than 70000 dots wrong are believed to live in the amazon region today. that one's warrior people live in anarchic society split up into small communities. some clans still wage war on each other but their daily lives in the rain forest

are primarily focused on on and working their small garden it's probably the women are responsible. from both was fascinated by the traditional lifestyle of the indigenous peoples as he traveled through the rain forest observing their customs and learning their languages in contrast to other explorers and researchers from europe who considered them to be savages he saw them as a group of people unspoiled by civilization but today's civilization is encroaching on the rain forest and its inhabitants to you or your car grew up in the community before leaving to go to college in the city a 15 day walk from here he's one of the few want you are to have regular contact with the outside world when i was very young snow and years old i always respect the nature. so i need to be a leader. i did

a lot of the ceremonies ceremonies ceremonies would shout out. all my families of sherman so i believe in god in the church so. i was really prepared to started to talk about my nationality. now to you or your car as the tribe spokesman he wants to draw the world's attention to the plight of his people the clock is ticking for the arch of war and their way of life beneath the ground of their ancestral homeland are huge petroleum deposits drilling and exploitation on a large scale would be the end of the who live in from and with the rain forest. for the auto we are warriors so we will never be afraid from their mother warriors because. if you cop to give our life for the nature we can do that so if the government wants to send all your companies here they're going to fight so if the

oil companies want to take flake out to kill. and then make a. material to make the money. they actually are oh tom lives in every stone every plant and every animal. they prayed to the spirit for protection and fertility. yet you are see the forest as a living being has rumbled himself sensed as he made his way through the jungle of the amazon region. he did away with the prevailing myth in europe of the british native by simply watching and listening to what the indigenous peoples had to say.

a pleasant flight. lift off to mars in 75 minutes on d.f.w. . i often kept the jet well i guess sometimes i am but most are laughing with that research and i think deep interest. i'm a culture of looking at the stereotypes claxton here think this leaves the country that i now live from. kiev need to be taken as drama day i'm still new to us it's all about ok bob i'm a joke to join me for meet the jetman funded up your. post. s.o.s. europe. is in crisis. the future you will meet champions young champions legislative optimists but i suspect spirit now for

a long time i took pieces of the things we value about europe for granted but now i sense this need be something that we can people in particular need to fight like a woman. comes to. me for activists from for a new country the flayers for the dream of a united church of. england they saved in european ideas. play with bonnie's and stand up to my pain fantasy and contribute to something important to note the coming up see of. the future as europe starts september 2nd on d w. played. played. such
