vishal warning of some cracking two days before the structure collapsed but the university says engineers minutes before it collapsed and concluded a crack in the structure was not a safety concern those were the headlights to stay with here. the nativist news as it breaks it's an estimated ten million children of school age are still roaming the streets of baghdad with details coverage children what amala face and number of serious problems from chronic child malnutrition to a stream of poverty from around the world should one is last us lawsuit in two thousand and ten by then needs more than twenty million dollars in legal fees. this is techno innovations that can change lives the science of fighting wildfires we're going to explore the intersection of hardware and humanity and we're doing it in the unique way. this is a show about science blow not the ice scientists. tonight

techno investigates shrimp safety the seafood by nature is a high risk commodity for americans love their shrimp but most of it comes from countries that use extensive antibiotics that could make you ill now techno goes inside the federal testing program american food. that's supposed to protect the food supply doctors should do some more is mechanical engineer she will share the results of her investigation to how dangerous is that for human beings and i'm still torahs i'm an entomologist visitor shrimp farm in the middle of indiana yes indiana that could revolutionize the industry well this is like a little laboratory here yes it is and i'm sure for terrorist santa maria is a neuroscientist. imagine that you are one of the first to take

a trip to mars. this is the definition of pioneering that's what makes it exciting that's our team now let's do some science. yasser. hey guys welcome to techno on phil tours joined by dr should you some are in a real because of one of my favorite things is shrimp sizzling away on a hot grill but i also have a fair amount of hesitation when it comes to actually knowing where that shrimp comes from and you may not realize it but shrimp raised overseas can have high levels of antibiotics and other additives that don't always pass american safety standards and america imports a lot of shrimp ira billion pounds worth so we're also the food and drug administration the agency responsible for policing us ports if we can follow them while they test unsafe shipments.

america has a jumbo appetite for shrimp it's a little piece of flesh that they could be in c. it's kind of like popcorn of the sea americans it's an average of four pounds passes. at fred sixty two. chef fred eric serves a lot of shrimp it's very difficult as a chef or a restaurant or to buy shrimp with the confidence that what you're serving them is going to be good try called fresh which. americans taste comes with a price. ninety percent of only shrimp eaten in the u.s. is imported. much of it from countries like india thailand and indonesia sometimes trip is raised overseas using production drugs like antibiotics that are proof for use in those countries but not approved for use in the u.s.

johns hopkins microbiologist david love surveyed federal data on drugs found in imported shrimp some of the top drugs that we found in shrimp were. i call tetris. and instructor meissen what does it mean for the consumer to be exposed to antibiotic resistant bacteria if you get an infection from these bacteria it can be hard to treat using antibiotics especially if these bacteria are resistant to the antibiotics that your doctor would prescribe. for bombs that use antibiotics often farm with overcrowded pawn diseases are a big deal in term farming can be a high mortality rate and some farms. the food and drug administration polices shrimp imports. five point five billion pounds the thing it is imported into the united states every year and

much of it ends up in a cold storage facility like this one in southern california but only a tiny fraction of all of that seafood is actually inspected so we've come here today to find out exactly how the f.d.a. . emily morrison is a veteran f.d.a. inspector collected one subsample out of fifteen random boxes and now in the process bagging them. put them in coolers. and ship it to the lab a computer system red flags imports believed to pose the greatest risk based on country of origin and the company's past history of violations. by nature is a high risk commodity lease heads inspections at the ports of los angeles so there

are many boxes here they're all packed full what percentage of the sample gets chosen to be taken to the lab so review all electronic transmissions and we utilize things. like foreign inspection domestic inspection whether it was sample and another for all that information's gather within the predict application and then that shipment will be given a risk or the higher the risk or the more chances one of these officers will sample that much of. once the f.d.a. inspector picks some pills for inspection they're sent to an f.d.a. lab like this one in california. do you make you crazy only. i can imagine. that the shrimp is mixed with a chemical solvent dried and liquefied again run through an analyzer.

is an f.d.a. chemist the results are written from the tests what are they showing us in this post or compound fourteen forest monster programs and how dangerous is that for human beings virtual current is dangerous for human beings because it's costing the . earth. organizer for. the building of one cause the building of this equipment or working for one so you know its size swimming. so how many parts per billion is this result i was one to true cost of building so two grains and so in the olympic sized pool when you've managed to find it in that binary it's incredible so that batch of strength is not allowed in this country this is not going to be how long does the f.d.a. simply isn't testing enough on the imported market to really find all of these violent of residues dr rangan had

a study of imported shrimp for the june two thousand and fifteen issue of the influential magazine consumer reports of the two hundred five imported farm samples that we found a leaven of those actually had illegal residues of antibiotics on them and that comes out to about five percent of the imported farm shrimp samples being contaminated with an illegal antibiotic residue the fact that the f.d.a. only tests about point seven percent of all the shrimp in this country for those. antibiotic residues suggests that the agency is not actually testing enough shrimp to catch the amount of illegal residue products that may be coming into the market however many of the countries that export the shrimp permit the use of antibiotics when you feed low levels of antibiotics every day you're not feeding them enough to necessarily kill bacteria those bacteria can become resistant to those antibiotics

and that can make those antibiotics less effective in people if we're infected by those bacteria just as worrisome was the number of shrimp that tested positive for bacteria we found about a third of the shrimp that we had had vibrio contamination vibrio is one of the few food borne illnesses on the rise seven of the samples we found had mercy that's concerning too and that's probably primarily associated with the amount of processing that goes on the shrimp production both have the potential to cause illness through the cooking process they can be killed we do know that there are shrimp farms and shrimp production practices that are doing a lot more to address those issues that are addressing hygiene and addressing other issues so that they aren't heavily reliant on drugs or other chemicals. six hundred miles from the nearest ocean. windmills and soybean and corn fields.

home to. mom and pop indoor salt water shrimp for. their own there over time i know welcome darty of travis county. dear old brown accidental shrimp farming pioneers are you now at six pounds with thirty two dozen backyard pools is growing takes the perfect indoor system with zero waste no chemicals in the ninety percent survival rate. that's a third higher than traditional outdoor shrimp farms well this is like a little laboratory here yes it is in the short form yes it is we do nine tests every single day we do temperature design oxygen night shite c o two salinity alkalinity ph ammonia and flop as you can see our water is brown the test we're doing here right now is we're trying to see how much bacteria is in our water and we call the settling so you're basically waiting for all this bacteria to go to the

bottom and that tells you how much is it how much we have an exact like and for over a certain level then we have to get it out of the tanks otherwise it's going to start suffocating out the trap that's very important that has to be done every day basically we're not even farmers anymore we ask ourselves guardians of water as long as the water does what it's supposed to be doing the shrimp do just fine we add no antibiotics no hormones are ever added into our tanks you heard that right no antibiotics no hormones just fish food salts and baking so it's called head root troop with bio flux system a process that revolves around bacteria no it looks very room what is this room that i'm seeing the ground is the bacteria and the bacteria is why they sell their way so that they can survive without a major filter here's what's happening below the surface the shrimp eat their feed in excrete demonio the bacteria turns that into talks ignite troitsky other bacteria turn that into benign i treat and as the waters air raided the nitrates

turn into a harmless gas going around and around how long have you had this water for years and how does it compare to other short forms most of don't have water that law we by mistake actually kept our water it's like it's maturing it's like one now does and we just found out of the older it gets the better it gets and so too for the shrimp the growing process starts every month with about two hundred fifty thousand newborns called post larval zz nicknamed. now we're going to show you about r p l's and when they come in they're the size of an eye last so it's hard to see inside this water how many shrimp are actually in here we stock about seventeen thousand each one of my six tanks there so what are all these tubes coming down those are airlines that adds the oxygen and their oxygen and keeps everything in suspension because if this stuff settles i'll have twenty minutes and then twenty minutes i meant maybe that everything here seems so precise it has to be it's

mother nature will it is mother nature but with a lot of help from a mother in indiana i notice there's foam on top what is this foam foam is mostly c o two mixing with their feed that just comes to the top and it will actually disappear so it's part of the process is part of the process. yeah the song yes. this is what you see in the supermarket when you get a shrimp down as they said they can't because they had on their very translucent one of the characteristics we actually look for mine see the long and ten is one thousand they're happy. and they're intended to start their fast now they begin seeing here this is their only protection and these mad right now that mouthpiece have these very angry at me as well horn yeah and if you can look right where your thumb is that that's where the heart is that also you can see it start being. a

month later there promoted to the production team with the turn in to dinner they are. already out you know you have to keep don't do it after you. get sick. or you say a number of beds are brown so about five hundred pounds directly to walk ins each month at eighteen dollars thank you very much i did think they. told their know how to do two dozen start up form. in the u.s. as well as ones in switzerland and spain these companies are really innovators they're trying out new technology johns hopkins microbiologist david love studies shrimp production he gives the production like the browns a high grade with one caviar one that could ultimately make or break in the business world a lot of these farms my start out with a bang but then fizzle after a few years because they don't make money for the browns shrimp farming is paying

off no financial fizzle only sizzle as the business continues to grow as it already is just a back but the proof of their success is what ends up on the plate in this case innovation tastes pretty good when served with the profits that are so good. i still can't get over the fact that possibly the cleanest and arguably the best shrimp in the world may come from the middle of indiana so you get some. in the table it looks a little gross i get that but it's chemistry in there and good end result is really good there's a global problem with using a lot of antibiotics in farming the more antibiotics used the more we're going to start seeing antibiotic resistant superbugs it happens in agribusiness here in the us it happens overseas and it even happens in medical practice you know

a lot of people ask why should we care if there's some superbug that can infect shrimp how does that affect us but what they found is that bacteria can actually swap genes so potentially if the bacteria that infect shrimp becomes resistant it could swap the gene into a bacteria that infects us and so that resistance me passed on and the amounts of you know millions of pounds of antibiotics are being used around the world not just in trim but in cattle and poultry as well that is going to catch up to us when it hits our health care system that it's called it's. call the spillover event it's not a confection it's an infection that happens in an animal species and then just like that a human can get infected too and it's been the source of most deadly diseases that medicine can't keep up with and that's where you look at the numbers could we have a billion pounds getting imported here only two percent actually gets inspected what about the other ninety percent it's important to have confidence in the system moving forward if we're going to keep eating shrimp and the inspection process was

so random i mean the amount of shipping that came investors will actually made it into a lab is tiny care what you have come over is next you have really interesting story now imagine that you are one of the first pioneers to take a trip to mars but also imagine that you're not allowed to come home it's a one way trip which you guys do at. i met a woman who is already signed up and she's raring to go. for decades humanity has been fascinated with a manned expedition to mars. this is. the definition of pioneering. that doesn't scare here that's what makes it exciting robotic pioneers like mars curiosity rover have been crawling around the cratered landscape uncovering clues. about whether this distant planet can sustain life as we know it do you have the right stuff to have that right stuff

jamie del rosario is a twenty seven year old entrepreneur and c.e.o. of the international metal source a raw materials company that supplies metals to aerospace companies like space x. and lockheed martin she is one of one hundred candidates that has been selected by mars one a private company that wants to colonize the red planet the catch there's no return flight home what do you say to people when they say jamie this is a suicide mission why are you doing it call it as i said mission but it's something that i chose i'm creating my own destiny for myself and and if it's a destiny that would help humanity. i'm all for it. according to mars one one of the main goals of the project is to establish an interplanetary species to preserve the human race. i want to contribute directly to

mean kinds call for the expansion of the solar system which we have to look for point destroyed in the long she made it to the top one hundred the third round of a selection process mars one says started with two hundred thousand online applicants ultimately twenty four crew members will be chosen. do you think that anybody with enough training could become an astronaut i believe that if you have. the motivation and it's tearing a should have of wanting to do it you can a mission to mars is obviously no simple matter pasadena california is home to the mars program at nasa's jet propulsion laboratory nasa has taken the man to the moon and back but they've approached this journey with a much more deliberate and rigorous training program. i'm now on the base on mars and i will give you a little tour in two thousand and fifteen six volunteer scientists walked out of a dome on the side of a hawaiian volcano after being locked away by nasa for eight months this was

a simulated experiment of what life on mars would be like coexisting is one challenge getting there and surviving is an entirely different endeavor landing on mars is still pretty. can be quite a terrifying. dr richard zurich is the chief scientist for the mars program at nasa as jet propulsion laboratory a lot of things have to happen right right know we fly into the atmosphere we have would look for total but we're also trying to slow down so that we can while. we're talking about a very different scale. of endeavor we're landing a metric ton down on the planet today we think for human missions to get stuff down on the surface that they can use that they can be there for a prolonged period of time that means forty fifty metric tons that's

a lot of material today we don't know how to land the mars one has come under critical fire for their project primarily due to funding issues and for reports of recording the mission for reality television show. in march two thousand and fifteen c.e.o. basilan store took to you tube to respond they are currently selling our documentary series to international brawls costs or there's no deal in place yet but it's looking very promising there's a lot of interest when we really fell you a good criticism about our mission because it helps us to improve our mission also tells techno quote there are less serious critics who are only interested to sabotage our mission for example by lying but even if this non-profits mission never launches nasa is laying the groundwork today this is very much in the mode of there are going to be humans on mars we're in the first stages of trying to

understand what it takes to actually be able to explore with humans on the surface of the planet we've made a good start on a robotic program first let's get down there see what the planet is like people's first explorers out there on the surface and then we can see what the future holds not the million year but i want to go and colonize mars i mean there's so many risks it's so frightening to me what is the value that's different from me and probably from most of the people living on this planet who are afraid to go some people just have different goals and missions i want to do something that would change the world or help the world so if you are selected to go to mars do you foresee yourself. getting married on mars having children stay there to half isn't interesting because it will happen do you think that's going to be a part of your training i would think so i mean that's something that we cannot shying away from because we're the new frontiers of colony and i think another plan in the solar system are you scared leaving earth behind i will miss it everybody is

trying to get to mars and i think what stands out with my swan is a permanent settlement and i think this is the time now. so i'm really interested you guys would you sign up for a one way mission to mars i wouldn't you wouldn't mind. possibly but i don't think i would sign up for this one way mission the mars jewellers through history so many pioneers and explorers were to be fair a little bit crazy and sometimes they succeeded but other times they didn't but it always will push progress forward just a little bit through how i think the merit of this project is the fact that they go live to try to be able to achieve living on mars and the result of having a gold like that which is extremely ambitious is the amount of technology that's going to be developed you know just crazy inventions and innovations that are going

to come out of a kind of pie in the sky it's relative you know i think we've talked sustaining life on other planets versus sustaining life she wrong earth's really interesting topics today guys so thank you for them we'll have a lot more of these stories next on here in techno we'll see you then dive deep into these stories and go behind the scenes at al-jazeera dot com slash techno. our expert contributors on twitter facebook instagram google plus and more. we're talking about ivory poachers who have decimated populations of elephants in africa they almost always shipped the ivory out of a different country from where it was poached because that's where you start your search to look in the wrong place this radiocarbon dating method tell us their trade ivory is legal or not then we have a place who can focus law enforcement on take those out and perhaps the source of the r.v. from entering the network take note at this time when else is there

a. history is so often told through the eyes of leaders but in amritsar india just thirty kilometers from the border with pakistan this old building is being transformed into a new museum mallika. is the driving force behind sars hard to shoot museum it's really shocking because if you think about the fact that within a few years of nine eleven happening nine eleven museum was there and they are now numerous called the museum this is not beautiful the museum so hunches it on the wall and have walked to memorialize these events that have shaped them by dition is not about the political events that led up to partition it's about the impact on each person who went through it it's really important that we highlight the stories of humanity hopefully one outcome of this would be that we remember our

shared humanity and the shed history. of the country. until now the coverage of latin america that most of the world was a cloud cover included todd's tragedies of quakes and that was it but not how people feel how they look how they think and that's what we do we go anyway five and a half months of demanding it to an education system that was introduced to. latin america al-jazeera has come to fill

a void that needed to be filled. stories of life. and inspiration. a series of short documentaries from around the world. that celebrate the human spirit against the odds some of them from this ok so case. al-jazeera selects change makers at this time. this is al-jazeera. welcome to this al-jazeera news hour live from doha i'm dennis coming up in the

next sixty minutes the turkish flag is raised in the syrian city of affray in.
