better place. that's all that matters. >> well, welcome, you can get the latest on everything that we're covering by going to our website. the address for that is www.aljazeera.com. there you'll find all the latest comment analysis and video on demand. so do check it out. www.aljazeera.com. too off and could be detrimental to your health. a game changing way to detect cadgessers early. he is doing it with a smart phone, a 3 d printer and in less than an hour. and later. gnarly half the world's languages will be extinct by

the end of the century, the video game project that's got just out to save language, but bring it back into daily conversation. digital producer and co-host is here, he is bringing in all of your feedback, raj, you look at these otherused procedures and it is hard to not know someone that has had one of these. >> behind the stats there are human beings stories narrative, family and friends, and speaking about our community, we have a ton of stories about this on facebook. here is margaret, she writes i had degenerative district of columbia disease for years. i had a surgeon promise relief, but i came out of surgery unable to use my right leg. once you are in the it you can see it for the scam that it

is. >> americans spend roughly $3 trillion a year on healthcare, and some experts estimate that about a third of that nearly 1 trillion-dollars is on uns in procedures and treatments. from heart stints to himself recollect mys there's growing concerns that these devices are schedules far too frequently when other less expensive options could be used. >> raising questions of financial motives. in a washington post report, some experts estimated that nearly half of the 465,000 spinal fusions done in the u.s. in 2011 were unnecessary duke university reported 20 to 25% of defibrylators as overused. and unnecessary procedures to more than cost money, they elevate their risk. debilitating effects, life long medication, stroke, and even death can occur when wises and operations are used

that are not necessary. so who is at risk? and how and when should you challenge a doctor who may be recommending a procedure that fall squeeze the overuse category. with news the studio is rose marry gibson, the seen your advisor for the journal of the american association, she is also the author of critical acclaimed booked including the treatment trap. and out of jacksonville florida, she had spinal fusion surgery in went 2010, that she says was a mistake, and is still suffering from it. so rose mary, we are talking about overuse and unnecessary procedures, how do you really define otheruse or unnecessary. >> it is overuse is when the risks are simply greater than the benefits. we just shouldn't do it. >> well, in 2013, u.s.a. today, they did an analysis of medical research in government databases and they came one this list. it is the five most common

surgeries done that aren't negligence. and their list is, cardiac angioplasty and intercepts cardiac pacemakers, back surgery, himself recollect my and hip and knee replacement. do these bursts in the pead yeah really reflect the scope of this problem. >> that list are really the most common unnecessary surgeries that are being performed. and hundreds of thousands of people have them every year. and so i think that list is pretty accurate. >> but in terms of the scope of it, do you think that it is out there enough that people get a sense of the volume of these cases. >> i think there's a growing segment of the public that is becoming aware of all the necessary use. that's causing harm, but still a lot of people believe these things work, physicians have their beliefs that this is a good thing. even when they are shown

evidence to the contrary, so our beliefs are powerful driver of so much of this overuse, both gi the patient and by the fix. physician. you mentioned the goa use of stints, a lot of publicity big senate investigation, new york times story, turns out 20% of those people who had this unnecessary procedure still believed that the doctor who did it saved their life. so our beliefs are very powerful. we have our online community and we assign blame, how does this happen. >> at least accountability and bill says there are many kinds of doctors some became doctors to care for people some for the love of the money, he says focus on that. but i think the real issue is not that they are unnecessary, it is that they are preenter haveble, and too off we fail at preventing. ard cooing to the cdc over

200,000 deaths from heart diseases are prevented each year, we need to act on that and speaking on a preventable tragedy, hear a story, lisa mentioned you had receive add spinal fusion, was unnecessary, before that you were very healthy, how do you think your poor and what happened to you could have been prevented? >> well, i went to a hand doctor. i didn't two have a back pain, i didn't have a neck pain. and the hand doctor i thought i had carpet tunnel pause i had no feeling in my right index finger and thunderstorm. so this hand doctor said to me without doing any calling -- sending me to a neurology, to do nerve toasting which would have confirmed that i have this, he said he did an mri,

and he said will you go to up to dr. [bleep] because i don't think you have carpal tunnel because that's the irony. go in with problems with my hand, and the next thick i know is dr. [bleep] is telling me that if you don't get this done, you are going to lose all of your upper body strength and you are going to be a cripple. and you will probably get the feeling back in the your fingers. not only did he fuse my lumbar spleen, he fused my cervical spine. >> rose mary, dump chain for us overuse for profit verses overuse out of an abundance of fear? because we doctors do get sues left and right, is it possible they are doing more than they need to, because if they are afraid they don't they will get sued? >> it is true that physicians will do more diagnostic testing to make sure they

don't miss anything. that's the last thing you want to do is miss a serious it is, be uh it is a whole different mat tore do a back surgery on in a situation like this. it's not just the doctors, where there's a profit motive and hospitals, let's go upstream. in this case there are companies that make the devices used in these very complex spinal fusions procedures. when -- this is 2015, and it's 50th anniversary of medicare in 1965, there was not a single healthcare company on the porch 100 list. today there are 15. they have to keep making money. their shareholders are dend maaing a good return on investment. the only way to do that is increase sales and price. it's a really tough issue beyond doctors and hospitals. >> what are the long term effects of what you say is othertreatment? what are you living with every day. >> i am living with pain every day.

i have -- he only fused three, four, and five in my lumbar spleen, that left one and two but three, four, and five, are so heavy with this extra bone and these screws that they batter -- they act like a battering ram against one and 2. so the latest mri, and i have had many of them, had shown that they have just about decimated l 1 and l 2, they have been smashed so that they are completely collapsed. and i have a fracture in p my thoracic in t 11. and i have on going problems with this it seems like you're allowed two years before you can -- that you can actually complain about a doctor. but all of my problems happened after two years. >> rose mary, i am going to

pause you for a second, rose mary, when doctors recommend procedures particularly those on this list, how is a patient to respond so they don't undermine the advice of good doctor whose are working in your best interest. >> a good doctor will want to talk to you about treatment options. and their risks and their benefits. a good doctor will never railroad you into a procedure when you still have some concerns and unanswered questions. so look for a good doctor who will entertain a conversation with you. that's a good sign. >> rose mary, we ask them this question, do you think patients in american are properly informed to make the best decisions about whether or not to undergo elective surgery p i think doctors get used to saying what they think needs to be said. i think many people don't know the right questions. what are the right questions to ask? if it is not an emergency, ask what are my options besides surgery.

what can i do. what are the risks what are the benefits what is my life going to be like. what are the complications like. i would do a google search. do patient reviews, or customer reviews of spinal fusion. or hip or fee knee replacement. >> just know what is involved in the procedure, and it will give you a realistic understanding, they certainly are experts in what happened after they have had a surgery. >> such valuable information thank you so much for being here. while there are a wide range of devices there are have the little to diagnose early on. part of a team who are on their way to detecting several types of cancer in less than 60 months and they are using a simple blood sample, and the

cloud. leakages are disappearing around the globe, meet a team that has turned to the web and gaming to not obvious preserve, but make it a part of every day life.

o. >> welcome pack. we what are a lot about medical treatments but very little about advancing in early diagnosis. particularly cancer. our next guest is trying to change that, jorge is chief technology officer a bio technology company, he joins us now from mechanics coe city, jorge, welcome. so what are you are doing is sounding amazing you are on the path to detecting diseases. and you are using really simple tools like a basic blood test, and a smart phone, how are you doing this? what is

happening? >> so my co founders and i we found the a way to attend this fingerprint. we create a product that has three components, one it is pie owe chemistry, where you combine the blood sample. and then the device that is very simple, that is uses on the shelf for the electronic components. and the third one is -- analyzing the data and corelating this information with the process of the specific diseases. >> you hit on something really important there, you said it is very affordable, i think i read this test that you are able to do, that's in -- it is beta face, is about 50 times less expensive than current similar tests. is that the case? if it is, what do you expect your audience to be for this test. >> yes. just to give you an idea, a traditional device, a machine to run this reaction like

this, the cheapest one cost around $30,000 which is -- as a device we are providing it is around $150 so there's a huge difference. >> wow. >> and also on the bio chemistry, we are talking something around $100 as well for a single test. around 46 different types. that's our objective. to really democktize early cancer screening. we know that our online community is often times they are hosting the show, i would venture to say there is nobody right now who doesn't know someone with cancer among family and friends early diagnosis are red herrings when it comes to beating cancer, he says find the root cause. i am sure you disagree, how important is it to do early detection of cancer and how will your technology achieve that? >>

it is like -- it is night and day detecting cancer in materially stage, and the late stage, in stage one or two either rate is around 70%. it is around 5%. so there's a huge difference in that, it depends on the type of cancer. so cancer, it is a combination of inherited factors, randomizations and environment conditions. crow raise an interesting question, it at presents some ethical collages that have even been raised by john hopkins university. i want you to read a couple of things they say oversite quality control, treatment protocols patiented support, you know if a patient is tested in something is detected in a remote region from they may not have the resources to then move to the next step, how do you handle that?

>> so the objective of this -- we are not -- although we want to reach the masses this is not something you can have at your house, we believe it needs to be a consultant for your doctor. the doctor is the one that can give you the authorization of about what is next. not all diagnosis should go to surgery. and the different kind of people, there's people that are healthy, but also people that are high risk individuals. for example, people it is very helpful for them to be tested willingly. >> i would like to know about the cost, and reliability, it sounds very interesting though and i will definitely try to work this or dvri, so there you go we have a viewer. speaking about one of the negative at beckets. especially in the aiming of the sony hacks and the hacks

of target, aren't you worried about the privacy concern? this is a very detailed private records that will be put out potentially for the community and could put the community at risk. >> the device, we don't want to profit from it, we know there are smarter people out there that can help us. we are in the final staging -- so we have a platform that is very secured and satisfied the regulars. and also what we are doing is we are identifying microorganism patterns. we are not diagnosing people. that core lates to the presence of a specific disease, according to a previously published documentation that's the way we work on that. >> thank you so much for joining us, i know this process holds so much promise,

still ahead, parts of the human story in this country, and every other, disappear every day. but little hi-tech health is reviving and preserving one valuable piece of human history, indigenous language we will show you apps video games and a little crowd sourcing are giving old words new life. >> america's first climate refugees >> this is probably a hurricane away from it being gone. >> who's to blame? >> 36% of land lost was caused by oil and gas industry... >> ...and a fight to save america's coastline. >> we have kinda made a deal with the devil >> fault lines al jazeera america's hard hitting... >> today they will be arrested... >> ground breaking... they're firing canisters of gas at us... award winning investigative documentary series... the disappearing delta only on al jazeera america >> part of al jazeera america's >> special month long evironmental focus fragile planet

welcome back. animals and the environment aren't the only things critically endangered. so are hundreds of languages

but old dialects are being resuscitated with video games like never alone. it is designed to save the languages but make them a part of every day life. the founder of theth nose product, that using technology to help save disappears languages. and ishmael a native american story teller and creator never alone thank you for being about 7,000 languages in the world it is estimated that half of them will have disappeared. talk about these technologies are and thousand they are being used? >> well, there's a whole world of technology going on databases and apps but right now there's a huge uptick.

there's a lot of apps in the i-tunes app store, so that's where a lot of the action is happening. >> mark, what do these apps do that revive these languages? >> it is a trick question. because some of them are simple touch and answer apps. orrs have games and flash cards and dynamic endangerment pieces to them. but the technology itself will not save the language, not ammonal goes by where you will see a headline, human interest story, app to save language, and they simply don't. it is the usage of the apps and how useful they are to a particular community that will be the measure of the success. >> i have to imagine, just like aggregating all of these languages that are dis appearing has to be a challenge. >> this would not have happened 15 years ago, now there's a chance of preserving this language, but also

celebrating it and having outsiders like myself enganged with it in a rich way, and speaking about these i want to bring up first voices it is an app for the android, the mac, here is also endangers languages. on line, collaborative effort which seeks to protect the diversity. you can share, and add, and upload videos wow can record your language, and then people can chime in the, it is exciting. this is very important diversity thrives on different tongues it makes people interesting and unique, she goes how boring is it if everyone spoke the same language. and now it is maybe -- >> my own experience, enjoying the

humor, in p several native languages enriches my life and it enjoy it's multidimensionality. i am a gamer, we talked about video games often, lisa rolls p i eyes but it is okay. there's this beautiful video game, never alone, you worked on it, it is coming out soon are you using the same concept in a video game format, and share that really with the main stream audience, talk to us about how using video games specifically is either successful or not in preserving this well, i was the lead writer for never alone. i am learning the singett language, my mom -- however with this never alone game what i really hope it does is sparks a fire with young

people. that they can connect to it, they can see something in popular culture, that feels good and accurately reflecting their identity. you need to go into the community, you need to -- roy t mitchell a linguist, he talks about we need to have this as one of the three most important things in our lives. we need that much dedication so sometimes it can be hard. sometimes kit be a gimmick, so you have to use it wisely. >> is there a hope that these will do more than just peek the interest of people within these cultures but expose these cultures to larger groups. >> sure, but i think something as intimate as a language app will be individual that is part of that culture, there

may be a wider market. i do have my piece of bumper sticker wisdom which is a technology won't save language any more than a pot full will solve starvation. but to think that it is the technology, and it is not a technology problem, language preservation, and sustainable them, it's a human problem. and if technology serves the need then yes yeah, it will be a great technology, and useful and kit bring that hope if you are outside the culture, exposure to it, exposure to anything you weren't familiar with, then that can help you save thins. >> true. >> we would love to hear something in your native language, will you speak a little for us. [foreign language]

. >> i say thank you, i feel so good looking among you today. and there's like my grandfather, i called him cyril george who recently passed away, sting he always said is something that he said was left my prayer be that clingette will be everlasting will be there forever. what a beautiful way to end the segment, thank you to our guests and to all of our guests today until next time we will see you online.

a show about innovations that can change lives. >> the science of fighting a humanity and we are doing it in a unique way. this is a show about science by scientists. . >> tonight "techknow" vets the virus hunters. >> we want to understand the evolution of these pathogens. >> this team deals with the
