what secrets lie behind. discover new adventures in 360 degree. and explore. sites. w world heritage 360 getting out now. music it can be therapeutic and it can move us. to tackling cancer with a vaccine new hope in m.r. and a technology. music mix and they're all focused on this edition of tomorrow today at the science show on t w. smoking. alcohol. unhealthy diet. pathogens like

the hepatitis b. virus. pollution and some exposure just some of the known carcinogens. cancer is one of the main causes of death with nearly 10000000 cancer deaths in 2018 alone in the future some of these diseases could be prevented by vaccines. a customize vaccine created for an individual patient is particularly. fast effective and with few side effects that's the promise of new an r.n.a. technology in the fight against cancer. this tumor center in homburg oncologist is on his colleagues are preparing to start clinical trials as one of several european facilities testing experimental comes or vaccines. one of the most modern approach is essentially we are the immune system to take on the enemy in this case the tumor. what makes

a malignant tumor so challenging is that for years it can slip past the body's defenses with camouflage so clever that the immune system doesn't notice the invader or is too weak to keep the cancer cells at bay allowing the tumor to grow unhindered. that was the case with one of dr arnold's patients who wishes to remain anonymous his cancer was fine during a routine colonoscopy by which time it was advanced with metastases in the liver. back then my life expectancy was estimated to be just a few months it was an utter shock. luckily both the tumor in his intestine and the liver metastases could be surgically removed in a single operation the treatment was required to reduce the risk of the tumor

returning that's the best york of even the world's top surgeon can't detect single scattered tumor cells in the body that may even be dormant and not multiplying. them a doctor can't change the biology of this disease we know that latent tumour cells can survive inside the body for a long time and they can wake up and start to divide and proliferate again over them. after surgery chemotherapy is often administered to prevent this and to destroy the remaining tumor cells but the treatment also attacks healthy cells in the body. it feels like you're being filled with poison. with the help of a new m.r.i. and a vaccine the hope is to prompt the patient's immune system to target the tumor unlike typical vaccinations it doesn't involve injecting the body with deactivated

components of the disease. the messenger m r n a injected into the muscle tissue provides the blueprint for a specific tumor protein. once it has the blueprints the body then produces its own tumor modules the immune system recognizes them as foreign and produces antibodies the body is now armed with the knowledge of the enemy it faces . basically reversing the production process instead of making it in a laboratory with all the technical procedures it starts out inside the patient's body which ultimately produces it on its own to teach the immune system what it needs to know. the researchers hope the vaccination will enable the immune system to identify tumor cells in the blood early on before they form metastases. morris. for the immune system to keep

trying new tumor residues it or destroy them then the chance of recovery is greater . expect an upcoming study to shed light on whether that really works he investigates the immune system's response to colon cancer at the national center for tumor diseases in hyderabad. the n r n a vaccine in the study is made by minds based pharma company by on tech who's covert 1000 vaccine is based on the same technology. into being in the us bases are also using m r n a technology in the fight against cancer as well as cause it the goal is to give cancer sufferers personalized vaccinations in the near future. this is a real milestone we're no longer talking about months or years until it's ready just weeks its significance and potential efficacy have opened up

a whole new playing field. because while the focus remains on the coronavirus diac arnold and his patients will have to wait until their cancer vaccine is available the colon cancer patient hopes to have a ready beaten his illness by then but should the cancer recur he'd like to be part of a trial with an m.r.i. and a vaccine. to me initially it all sounds very promising with significantly fewer side effects from a patients point of view it's a great cause for hope. but how many vaccine doses does it take will the immune booster on its own enable the body to fight the tumor effectively or will it only compliment chemotherapy. there are still many small steps along the way that need to be understood for it to succeed to find out what the possible hurdles are. and that's why these studies are being carried out. it will take some years before the

results are known but oncologists worldwide are confident that the new technology will become a powerful weapon in the fight against cancer. customized medicine is the great hope for the future and it's none of the deal with regard to gender differences. from a medical standpoint men and women are not created equal sometimes and successful therapies are very different in men and women as our next report shows. had a heart attack last year and she's not back to her old self yet she'd always exercised regularly and was never sick she never imagined she might have a heart problem. i live a healthy life i don't drink and don't smoke. so i fulfilled many preconditions for

actually being healthy see. i didn't have any pains in my heart. so i had no reason to think there was anything wrong. with me mia it's often said that it's mainly men who have heart attacks but that's wrong women with high blood pressure are in fact at much greater risk than men with high blood pressure of having a heart attack and they're more likely to die if they have one. professor part aims to change that she's a cardiologist and a specialist in gender specific medicine with a focus on women's hearts does this all. unfortunately the imbalance in heart research is particularly extreme a new study for example had 85 percent male test subjects and just 15 percent women . because of a lack of data and clinical studies on women they suffer many more side effects

just want to know hoff to 2 times as many. months come up with this one was a few guidelines for treatment in clinical practice and what are considered normal values really only apply to men we don't have the equivalent for women. so i can live. off was lucky many women with heart problems don't go to the doctor because they don't recognize the symptoms in medical terms there are many differences between men and women with respect to the heart they pronounced women's hearts tend to shrink over time men's grows like the larger. professor gates has done research into this except ability of women's hearts to stress she conducted an experiment with 32 women and 32 men aged between 50 and 70 that looked at the interplay of heart and brain

a hybrid scanner images both soft tissue and organ function at the same time that's great for studying the interplay of brain activity and the heart that involved subjecting test subjects to mental stress as this information is that it's important for you to count down from 100 in steps of say to you reach 0 you have to do it just fast as you can ok ok. i'm going to we can see clearly that in the fia center in the brain this is a significant increase in volume in these 2 areas the fia center has been activated that. act. and now we look at the heart we can image that as well during the examination we can see very clearly that in this small part of the heart disruption of blood flow occurred after the stress. this kind of thing makes

women more vulnerable for example in the case of a heart attack so much in health in fact often. capehart has found that in women stress plays a major role in heart disease. or aim is to improve diagnostics and treatment. therapy needs to take a patient's stress situation into account and develop specific ways for women to reduce their stress levels. still feels weaker than before her heart attack adventures in gender specific cardiology may soon help other women seek and find the right treatment before things get too serious. if our blood is red why are you so i don't think you made me. do you have a science question you'd like us to answer. then get in as a video text or voicemail if we featured on the show you look at

a little surprise from us as a thank you come on just ask. to find us on our website d.w. dot com slash science or look for us on twitter. this is the there and then. it's played without physical contact. the position players her hands in relation to 2 antennas controls the pitch and volume of the music. and next report is about a device that allows every movement of the body to be translated into sounds. it's a technology that lends itself particularly well to special education and therapy. what if even the smallest of movements could generate a sound then almost everybody could make music with their body.

motion composer is a device designed to help people with disabilities overcome their isolation it was developed by robert wexler. the american choreographer and dancer who's lived in germany since 1990. which i have because our. major said we should consider every day lost on which we have not danced at least once. i don't think you meant it metaphorically it's practical advice we really should dance and make music every day it makes us happier it makes us more human. what snow wants everybody to be able to do you say whatever their physical or mental abilities.

it's been a minute as for unattached my opinion that we're all dancers and all musicians that's the principle underlying motion composer it lets us all live out these instincts. whatever our abilities. in the 1970 s. in new york started experimenting with motion tracking. dancers movements were registered with the help of sensors attached to their bodies. and then translated by now electronic devices into sounds. ok dr march i thought this is fun perhaps we can work on it until anybody can do it. what sort of followed through on that with support from the powerhouse university environment and funding from the european union p n

a team of software developers composers and therapists got down to working 2010 to develop the technology and make it easy to use. this motion the principle behind motion composer is that if we make a movement and this movement triggers a nice sound. and if we realize that we made that happen ourselves and then we're already making music and dancing. in the one pound. has come to this t.v. studio. he's here to demonstrate how motion composer works. to have off with the biggest challenge in developing motion composer was the engineering. this sound like this

or this was no handbook to refer to we had to try out a lot of things. and we can. use motion composer have to grasp that it's their own movements that are making the sounds that's the case. to cameras register movements in 3 day. software imo lies is the data and translates it in real time into sounds. and. even the tiniest of movements is enough. the device features a great of different musical environments and soundscapes that i'm. going to put i know. you can move and compose alone or with others.

or mention him down for people with disabilities this complaint important role to view it's easy it motivates them to move. to express how they're feeling and to interact with others. and that's what's important in the businesses are her. as a tool to stimulate movement motion composer can be used in creative approaches to therapy rehabilitation and specialized education. dancing making music and in front of an audience can be a whole new experience. in my most people's reactions are really intense full of emotion and joy it's not uncommon to see people cry it out workshops tears of joy joy it's

a really beautiful thing. as adults robert wexler was often in the limelight. with motion composer he brings others out of the shadows. this sounds melodies and rhythms of music evoke different emotions and as. the feelings we have about a particular piece of music may change over time that. the music that once seemed romantic or uplifting might now sound cheesy or old fashioned. but there are all the hits that stand the test of time what makes a song a hit can it be boiled down like that science is trying to find out.

mash it. this 2. and this. one makes a hit a hit that's what brain researcher vincent chong wants to find out. i really enjoy music and the question i really wanted to ask is what makes a song so powerful and so motional. why do i get such a strong feeling when i listen to the music that i enjoy. and his team analyzed $80000.00 chords in $745.00 songs that reach the u.s. charts a computer program calculated whether each chord was predictable or unexpected in the context of the whole track. then they played the chord sequences stripped of melody and lyrics to a selection of test persons who then had to say if they like that.

our brains work hard when we listen to music it stimulates the parts of the brain that process ound but also the parts responsible for our emotions memory and knowledge. he experiment showed that 2 factors in particular increase the likelihood that the test person liked what they heard. for the 1st instances where the uncertainty is low and the surprise is high and called for a good see if the chord progression is fairly predictable most people are happy to hear a surprising chord and it works the other way around too if the chord progression makes you feel like you don't know where it's going to. most people are happy to hear a predictable chord about caught in other words it conforms their expectations. good music skilfully manipulates us we like music best when it comes sounds our

expectations. could this principle be used to develop the perfect formula for a number one hit. stefan bowman has a doctorate in music and artificial intelligence to him vincent chung's study demonstrates that the chords in chart toppers are mostly simple ones c. major is the most commonly used just chords make only rare appearances particular chord progressions are also common. for chords dozens of hits. this australian band created a medley of popular songs all set to the same chord progression. and trio. to the place. down the sound means and. we can see.

that clip goes to show that most smash hits are pretty similar to the us from a there's been a search for a good formula for as long as i've been working on the field yemen could people have set up companies focused on hit song science which flopped awfully because they hit a piece of music ultimately depends on a cultural context that changes all the time and that is not for its why that's why you aren't interested. in other words pop is all about the zeitgeist whatever the latest sound is plus some clever marketing and these days certain genres and all. artists are also promoted with the help of recommendation systems. hit song science shows that track speech or in the word you are more likely to climb the charts. still success can't be guaranteed there are too many variables not to

mention the goosebumps factor. yulia bristol is a ph d. student in computer science at the german research center for artificial intelligence she monitors test person's skin conductance while they listen to music for signs of stress or emotional response she herself reacts positively to this song was. sent to have been you know me. a combination of the female vocals and the melody that appeals to me it seems to have depth that moves me what. the signal registers this responds to the i.v. . are others likely to respond the same way this sort of data could be gathered on a large scale and be used to train machine learning programs to identify what sort of music is most likely to trigger an emotional response in listeners. another

approach is to analyze a database of songs and then create similar compositions. in 2016 daddy's car was the 1st song ever written by a i. was. the program was tasked with creating a new track on the basis of 45 beatles songs. he sleeps around food each of. the latest software is able to modify tried and tested hits ad infinitum. hotel california for example. this. could be a brand new hit or is something missing. the feel the songs were. many songs were written by someone unhappy in love depressed on drugs

or in a state of euphoria a machine doesn't have to try to just switch it on that it gets to work it has no sense of mortality it just runs and runs. across. might be an ai experts but his musical taste is old school he believes the hit song should be moving and unique but going by spotify algorithms hits are becoming increasingly formulaic it's something proves popular it's copied a lot of music producers who work with different artists repeat themselves music is getting ever more predictable and ai will only consolidate the trend. it probably won't be too long before researchers come up with the perfect formula for a number one hits but will these songs give you goosebumps like the hits of the past probably not.
