says, have made several arrest and use what attendance to dispatch crowds, intel a vive, during anti government protests as thousands held a vigil for hostages still held by how much after it's tara attacked on october 7th, stay with us. and there's also one who is a dw com and told me all logical thanks for watching the these places in europe, smashing the raincoats. step into a bold adventure the treasure map for martin club to discuss some of your regular reading sites on youtube. and also i wish i could've done more the same. you just click away,

find the best document on you to really see the world as he's never seen it before. the dr. know to dw talking entry, the right now hundreds of thousands of people around the world. a waiting for organ transplants like 4 year old, a v. green who's been waiting for a new hoc for a year will smart technology revolutionize organ transplants. and all 3 d printed organs anywhere close to becoming the norm. find out on shift. it's a hot may from human cells using ice 3 d printer scientists, intel of they've already made this breakthrough back in 2019. the printed hot couldn't be yet, but it was assigned the researches were on the right path. the key here is printing using living cells, circled by printing. id printing. well, the other 3 d printing,

also known as additive manufacturing. laughter has been in use an industry and for a number of years up yet it basically means building complex objects layer by layer hiding young and a few years ago. and this trend also made its way into the field of biomedicine filled us in all we've been naked up in need. it enables us to print the layers of living materials and that's my logical material. teeth which are very complex material properties. these things all fixed lives and for the world all phone cutting, the ones that we now have you possibilities and file medicine complaint can hopefully print complex oregon structures in the future using 3 d bio printing of the key to all the bio printing just for the bottom, funding had sustained. so science is can actually print organs using living cells. that's pretty incredible. in 2022, the 1st 3 d printed it was transplanted into a volunteer in the united states. but that was the last we heard. we reached out to the company 3 day by

a therapeutics several times for an update on the current clinical trial without any luck, but this much is clear. the race to manufacturer functioning organs using 3 d printers has been going on for years. first attempts to fly printing artificial organs were made over 2 decades ago. one of the trail blazes is us surgeon, dr. anthony atalla in 2011 a 3 day printed accuse me. thus the organ is measured using m r i scans the data is then used to create a 3 day model which has been sent to the printer. the printer manufacturers the model layout by layoff, from living cells, all as shown here from plus a race such as noting. and trent university develop basically using a 3 d printer in 2021. it looks deceptively real, but it's actually made of synthetic materials. it's supposed to help train doctors to recognize live a cancer in 2020 to 3 day systems and united therapeutics presented

a 3 day printed long structure. this synthetic creation should help regulate gas exchange the way healthy lungs do. animal testing, shoot off insight into how it functions it will probably still take some time before 3 day printed organs will actually be able to replace traditional organ donations. but this technology is already proving to be very useful in medical research today. like this 3 d printed bought a cop made from synthetic material. race such as at the massachusetts institute of technology in the united states have developed a road, bought a car using a 3 d printer. the replica is supposed to emulate the functions of a patient's individual heart researches 1st create a 3 dimensional computer model using data from the patients hot. it's made up of the soft, flexible synthetic material. the, the artificial heart is wrapped in slaves that mimic

a hot date. h. one is controlled separately to ensure that it pumps realistically, this way the rug bought a car and mirror a hot date of the patient. researches one to hone in on how the patients thought is contracting. robotics is not meant to be transplanted. instead, it's supposed to help doctors better understand the hot conditions of individual patients. and therefore i pinpoint the best treatment very helpful for treating people with hot conditions. but not a solution for patients waiting for an actual hot transplant. still 3 day by printing can be deployed in other ways. lots of patients who need a bypass due to block vessels, researches in northern germany, a testing out this idea of vascular surgeon, dr. ruben bands on his team and developing a new procedure speaking and fees isn't in artificial vessels, are in

a georgia dream and surgery from the actual company in one of the cardiovascular surgeons. you and have typically end up in a situation where you're caring for a patient, but don't have any suitable material to use for to bypass. and for example, i must, i'm for a heart bypass or a bypass and the leg and researchers have been working for many decades now. i'm creating by artificial vessels in the land. yep. so standing in level view, it would enable us to help perform a bypassing patients that don't have the necessary bodily material. i expect them to bypass on beating the research teams idea. a princess single tenuously presses to liquids to create a flexible, to made of bio materials. that's roughly 30 centimeters long. one of the base liquids is so cold by a way, it's a positive organic stink that's enriched with even investigative cells. it's crisis is l genetic material made from brown out what is a normal and back to the soldier noticed that cell is country bind well to it. so

that's why we have peptides which are small pieces of proteins that can be found in the human body like college and you need to pay the sounds good. now bind to these peptides cubic even the peptides can also send signals to the sales so that they feel comfortable then can survive and reproduce and bianca after and initial phase using standard straight printers. the team is now switching to a robot with a specially developed printed one chain. the in the print head contains the boiling . while the other contains calcium, fluoride stabilizes the bypass graft. let's design. this may look relatively simple, but it actually requires fine shooting. a lot of different parameters in parallel, the how sort of 11 challenges the bio into it does not have no technic properties. in other words, it behaves differently from typical liquids. becomes more solid under pressure eva um, but just means we need to equip the printed resistors here to ensure

a uniform flow of the by a wing mcginnis, and who move in 1st the few instead of allies. it's all incredibly delicate and precise look. so it's no surprise that the researches have carried out countless test prints. one challenge, the entire structure needs to have a consistent thickness theme is for as many cells to survive the printing process as possible. if everything has gone smoothly, numerous green cells become visible under the microscope. in the next lab test phase, bypass graft a being tested in animals. clearly a controversial ethical issue. but the scientists say it's necessary. and on that topic, 3 d printing with living cells could actually even help to replace animal testing. for example, when developing new drugs, pharmaceutical labs could use so called organ on a chip models. these devices can emulate how human organs function thanks to buy a chips, the need for animal testing could soon be reduced. the cells on so called organ on

a chip systems biologically, mimic human organs. when they come into contact with active agents, instead of animal testing, researches are increasingly using these kinds of many labs. it helps them to sun, if substances toxic to the human body or whether they could work as medications. the system basically consists of a microscope slide, at least one cell culture and micro channels. the membrane works as a carrier for the cell culture, while the micro channel supplied with f nutrients and active agent pot live. uh, excuse me, cells can be grown onto the chip or printed on slide using violence. sensors allowed to sign system monitor the condition of the cells home and ship. many of the bar trees have also started using coaches from multiple organs on the same chip, reducing the number of tests. today,

there are even chips with complex 3 dimensional cell structures, which allows for more precise testing. 3 d printing using living cells, certainly books, very promising. of course, it would be even better if we could print cells and organs exactly where they needed inside the human body. and scientists are already making big strides. check it out. this is an experimental meaning 3 d bias to could directly print by material until opens and one day it could be deployed inside the human body. we can directly deliver multiple in the lay on the table inside the bin body. and quite the coloring involving tennessee, they have to make well material outside of the body. and then in order to deliver that material to have to be quiet when says re a bunch and ready to quiet last infection and luck. last, similar to an endo scope, the soft, inflexible robeteck is inserted into the body by the through the mouth and a small,

a small skin incision using bio ink. the device can print by material onto the organs and tissues. for example, to tell them after an injury. so this is a larger version of our 3 d ball printer. we have this is basically use you to, to live up on materials to the engine side or off of the surgery to facilitate to the healing process. we have a camera located at the tip for the visualization, as we can see right here. and we have one channel at the top, 2 for the delivery of the materials. and of the fact we have the control us to control the bending of the printer. and it doesn't lead print, it can also make incisions and spray water to clean the wounds after an operation in the future, this medical tool could be used for different types of surgeries, including the removal of cancer risk treatments especially nifty fi can be utilized

on in one set of co device they can before them, they an course a big safeco for seizure, and therefore they can do more to sit and tie up kinds of timble inside the bodies . i think actually article on kind of sense, there is so much of groundbreaking research going on right now. but what people who are waiting for an organ transplant need the most is more open donors. would you're doing night your organs, or do you say 3 day printed organs as the way of the future? let us know. and so you next on the

gone with the wind, revered to this day, 10 oscar films that made history milestones of cinematic arts. and how they changed the world, the name on d w, the truly treated by western european patients of the norm and medical textbooks. does that lead to discrimination against people of color and medicine? does it result in false diagnoses? and more complications is the racism in medicine in 45 minutes on d w plus he's got issues with a lot say what?

the in 94 years of the academy awards. they've been hundreds of oscar winners. but 10 actually changed movie history. the american, the 1930s was sharply divided along racial lines. even in the mixed movie theaters, black people had to sit in the balcony.
