>> a possible clue - australia says that it's found two objects in the indian ocean that may be related to the missing malaysian airliner. this is al jazeera, live from doha. also ahead - gun fire and explosions in afghanistan as suicide bombers attack a police headquarters. >> what russia has done is

wrong. >> a heated exchange at the united nations - russia and the u.s. trade accusations over moscow's take over of crimea. >> and syrian refugees in lebanon are getting caught in the crossfire as government forces strike at rebel fighters. >> australia says it has found two objects in the southern indian ocean that could be linked to the missing malaysia airlines plane flight mh370. speaking in parliament, prime minister tony abbott said that images were picked up on satellite and aircraft is searching the area. three more will arriving later. >> the australian maritime safety authority has received information based on satellite

imagery of objects possibly related to the search. following specialist analysis of this imagery, two possible objects related to the search have been identified. we must keep this in mind. the task of locating these objects will be difficult, and it may turn out that they are not related to the search for flight mh370. >> we will be live in malaysia in a moment with our correspondent nicole johnstone who is standing by in kuala lumpur. first, let's go to sydney australia and speak to our correspondent there, andrew thomas. the australian prime minister standing up in parliament to reveal the findings, the australian maritime agency calling them credible sightings. >> well, i think the first sign that this was a potentially important finding was that tony

abbott stood up in parramatta, not only for australia, but the whole world, the fact that he stopped the working day to make an indication that this was a big development. >> two hours ago now, there was a press catholic church, and they went into detail about what the satellite images show, floating on the ocean surface. here is a little of what they said. >> the objects are relatively indistinct. i don't profess to be an expert, but those who are indicate they are credible sightings. the indication to me is of objects that are a reasonable size, and probably awash with water bobbing up and down out of the surface. >> reporter: do we know the size, like a basketball or seat

kushion or larger than that? >> larger than that. the largest image i have seen was assessed as being 24 metres. >> and another - a number of other images in the general area of the biggest one. >> where to from here. what's involved in a search of the objects. >> well, these objects are there. as you heard, one of them 24 metres long, that's a seizable object floating in the see. so far all the search authorities have is a fuzzy image. the crucial thing is to get human eyes to the area to look and see what that and other objects are. there's an orion search plane circling the area. one of the those planes is on site. three more over the next few hours. we'll take it in turns to go to

that area. this is a remote part of the southern indian ocean, four hours flying time, from the nearest royal naval, air force base outside of perth. once they get there they only have the fuel to fly for two hours, before they have to return. a commercial ship is in the area. they've been asked to check out the area. an australian naval boat is some days away, but is heading to that area as well. that boat, if there are objects, objects to take on board, it could do that. these objects are from malaysia airlines flight mh370, and i caution that is a big vote. >> thank you for this, andrew. >> the malaysian authorities are meeting their australian counterpart to discuss the findings, here is what the acting malaysian transport

minister said. >> the craft and the vessels - you know how huge the area is. >> reporter: how long will it take them? >> every lead is a hope. we have been consistent. we want to verify, corroborate and we are in that process. >> reporter: have you seen the image? >> let me meet the australians now. >> to nicole johnston live from the malaysian capital, kuala lumpur. journalists were able to get that out of the acting transport minister. has there been any official rehabilitation from malaysian authorities yet? >> that's right. they've only been able to get the brief statement so far, saying that any clue is hope. no word from the malaysian authorities. we expect to get that in 1.5 hours time, during the briefing held at the media center. >> the australian prime minister tony abbott spoke to the malaysian prime minister, and he told him he had found the two

objects in the sea. the malaysians released a brief statement cautioning that they don't know whether the objects are linked to the missing claim, so it seems as though the malaysians are being measured in terms of how they treat the news. in an hour and a half we should hear from them. >> i guess the families of 239 people on board will be anxiously waiting for any news about this. that's right. they've been detroit to get any news or information that's actually confirmed. so they are still in the same situation they've been in for the last couple of weeks, which is different pieces of information come up, and they are waiting for it to be verified. as the australians said, that could take time even if they do

manage to locating the objects. we saw how upset and frustrated and impatient many of the relatives of the missing people on the plane are, and we had two chinese women come into the media center upset, trying to protest and say that they weren't getting enough information from the malarp authorities. the -- malaysian authorities. security guards would not let them speak. no doubt the information in australia detracts from the problems that the malarp officials had -- malaysian officials had with the media and the chinese women with their complaints. they are looking for some good news. >> nicole johnston joining us from kuala lumpur. >> let's talk to zoe, chare, a relative of a passenger on board flight mh370, and is joining us

via skype from perth. it's good to have you with us here on al jazeera. if i can ask how you are related to one of the people on board? >> hi, actually, not one of the passenger, it's one of the crew on board. she is my relative. actually until now i'm still, like, waiting for the good news, and i'm following the news, like, every day, hoping that there's more and more information. >> and what do you make then of the findings from australian authorities? >> sorry. >> what do you make - what did you think about what australian authorities, you're in perth, what australian authorities have announced today that they have found two floating objects in the southern indian ocean that they call credible sightings, and are now looking into.

>> for me i think because there is still not a confirmed if there is flight mh370, i was waiting for the confirmation. if there is any informations or anything about the flight mh370, it would be great. at least there's some things that we are looking to. instead of missing - just like that. >> well, it seems, ms choy, every day there has been another lead, hasn't there, in the search for the missing plane? how have you and your family been dealing with so much speculation around where this plane is. how difficult a time has this been for you. >> actually from the day one there are so many speculations, like we request, get off listening to all those speculations, because we just

get that things after that, there'll be bad news and all that stuff. but, however, we are still looking forward for the actual informations. i believe they are trying very best to do the search around the world. >> well, there has been a lot of criticism, hasn't there, of malaysian authorities handling of this investigation. i mean, do you think that they've done their best. do you think they've done all they can to find the plane? >> for me, things like different - as long as they try their best, i think malaysia tried their best to do the search, like as many as they can, as much as they can, to do whatever search they can. >> what keened of support has your family received by malaysian authorities in the

past 12 days. >> at the first few days, they are still waiting for the informations from the malaysian airline's office. and until now, they keep updating my family members on what is going on, and stuff like that. >> okay. and i understand that you are a flight attendant yourself. so what has been going through your mind as this has been unfolding? >> actually, at the first day when i heard about the news, i was quite upset as i'm a flight attendant as well. i'll need to move on with my job and everything. i need to calm my family down to make sure. this in normal case happen, but

i believe i can cope with it >> thank you very much for your same. zoe choy, a relative of a crew member on the missing malaysian airliner, joining us from perth, thank you for your time. >> seven taliban suicide bombers backed by gunmen attacked a police station in eastern afghanistan. at least 10 officers and a civilian have been killed in jalalabad. a journalist and two police officers have been wounded. jane ferguson sent us this update a short while ago. >> the attack started as a dawn raid. at 5:30am, a huge car bomb exploded at the gates of police station in the center of jalalabad city. after that attack, they ran into

the police station and that's when the sooej began. afghanistan's rapid response unit to the national army and police were on the scene, but this went on for over four hours. now, the taliban claimed responsibility for the attack, and the fact that it happened in the center of jalalabad and distribute one, in a police headquarters, that is next to the governor's house shows how serious a breach of the security this was. the timing is significant. in just over two weeks, afghans go to the polls to vote for the new president. many are concerned that security could not just cause elections but delay them. candidates have to campaign in public and speak to the public, in an atmosphere of a lot of risk. the taliban said openly that

they'll target anybody that has anything to do with the elections. that includes security forces. >> egypt told al jazeera that 10 were killed and dozens injured in the anti-government protest across the country. the health ministry says two were killed. among them was a teenage boy. former president mohamed morsi was off theed in july last year. at the same time two egyptian soldiers were killed. the interior ministry says the armed men were from groups based in the sinai and happened when the police raided a weapons storage facility. >> special forces control the area and every entrance to the storage place. there were six people inside, but two army officers were happy that the operation was smooth

and successful, and they appeared and started firing. >> egypt's interim president said he will spare no effort to release the journalists in prison. he made the pledge in an alert to peter greste's parents. he has been detained for 81 days with mohamed fadel fahmy and mohammed badr. they are accused of having links with a terrorist organization. abdullah al-shami from al jazeera arabic channel has been in custody for six month. al jazeera rejects charges and demands their release. >> the next court appearance is on the 24th of march. >> ukraine is preparing to remove its soldiers and families from crimea. on wednesday, pro-russian forces took over two ukrainian navy bases. trmpts ukraine is to appeal to

the u.n. to call the crimea a zone and call tore the withdrawal of troops of russia from crimea and deal with the relocation of ukraine's military it troops from crimea to ukraine. >> an emergency session of parliament started in kiev. paul brennan has for. crimea dominating proceedings, but it seems as though the government in kiev is continuing as part of ukraine. >> that's the position of the government here in kiev. don't forget, they do not accept the results or the operation of the referendum that took place this weekend or last weekend, and insist that ukraine will remain complete, only when it has crimea as part of its territory. they do not accept the legitimacy of russia's annexation of crimea, despite

the fact that practically it's a fait accompli. that said, the measures they are debating guarantee the rights of crimean tatar. the minority population, and guaranteeing property rights for ukrainian citizens who are living in crimea. one wonders how they hope to enforce those rights, if they pass them through in the draft bill. the fact is that this is more symbolic than practical. >> there has been some good news, hasn't there, for the government in kiev - news of release of some hostages. >> indeed. you'll recall last night where this dramatic escalation in hostilities with the storming of ukrainian nav ail headquarters in sevastopol lead to the surrender of all the personnel inside, and the arrest, detention, abductions, call it

what you will of admiral highduck, the commander of the black sea fleet. he was taken away by russian special forces and it took the intervention of the russian defence minister to get him released. the acting president here in kiev demanded his rl. the russian defense secretary intervened and insisted authorities release him. he is on his way back to kiev. in other good news civilian hostages, basically pro-ukrainian activists in crimea, they, too, have been released and are on the way back to what has been described as continental ukraine. >> that's paul brennan in kiev. >> well president obama says the u.s. will not take military action against russia over its take over of crimea.

there was an angry exchange of words between the u.s. and russia at a tense session of the united nations. james bays has more from the u.n. >> most of the countries around the world believe russia is guilty of a major annexation. russia is not embarrassed by in and its ambassador is not backing down. at times he sounded triumphant. >> translation: yesterday a truly historic event took place. the you unification of crimea. an historic injustice has been rited. >> ambassador vitaly churkin attacked the comment and said the u.n. person produced a

one-sided report. >> translation: we have taken note of a number of western partners, who cannot rid themselves of colonial parties who impose their writ. >> a thief can steal property. it does not confer the rite of ownership on the thief. in closing let me emphasise what russia has done is wrong as a matter of law, wrong as a matter of history, wrong as a matter of policy, and dangerous. >> her comments angered ambassador vitaly churkin, who asked to speak again. >> translation: it is simply unacceptable to listen to the insults directed to our country. if the the u.s. delegation expects our cooperation in the security council on other issues, ambassador power must respect us.

>> as me left he added this... >> ban ki-moon is starting a visit to moscow and kiev, and the aim to de-escalate the situation. events in the region, and the language around the security council table suggests that tensions are rising. james >> we are in cuba where car ownership is being relaxed. but the locals are not finding easy deals on these wheels.

>> good to have you with us. these are the top stories on al jazeera. australia says it found two objects in the southern indian ocean that could be linked to the missing flight mh370. an aircraft is searching the area, and three more would arriving later. the australian maritime agency says one of the objects measured around 24 metres. >> in afghanistan seven taliban suicide bombers backed by the taliban attacked a police station. 10 officers and a civilian have been killed. >> local sources told al jazeera 10 were killed in the anti-government protests across the country. the health ministry maintains that on two people were killed. >> now, the syrian government are shelling hundreds of fighters that fled across the border. the crossing has been closed and

they have been attacking rebels. refugees in the areas are reported as having been hurt. it's come after the fall of yabroud on monday. let's go to stefanie dekker, joining us from the lebanese capital, beirut. what is happening on the border there? >> it's an ongoing tense situation. what we know is 300 fighters crossed into lebanon. this is the med evil castle. it's close. you can see these areas are a valley. it looks on to the syrian side. it's close. they have crossed. there was low moral. they tried to retreat. what we are hearing is there are syrian, lebanese, palestinians, and from our source, and a lot

of areas are armed. there is fighting ongoing between lebanese supporters on this side and the syrian army, we are hearing two houses have been burnt down in the area because of the shelling. so people are saying it's incredibly tense, and there's a highway interest tripoli, which is a port city in lebanon, the second largest city where there has been a lot of violence. 15 people have been killed. it's now blocked. people are very concerned. the bigger picture is that the syrian government is making head way in securing the border with lebanon. we saw yabroud on sunday, and a few more villages. air strikes are going on. the repercussions seem that more and more fighters will cross into lebanon, which is concerning. >> stefanie dekker joining us from the lebanese capital

beirut. >> to the u.s. now, where more than 100 immigrants have been found in a house where they were suspected of being held against their will by human traffickers. 94 men, and 15 women discovered in the property in texas, outside houston. many were dressed in their underwear, it discourage them from escaping. five men have been arrested. >> now, cuba has relaxed its rules for locals wanting to buy cars. for most it's an unattainable dream. adam raney reports from havana. >> cubans will do anything to keep their beloved cars on the road. since the revolution, car ownership has been restricted. cubans have had to be resourceful to keep their old cars chucking along. >> restrictions on car ownership have been lifted. many hoped to get a new set of wheels, but prices shocked

cubans. this is listed at $262,000. 10 times what is costs in most countries. every day people visit dealerships to see the unbelievable prices. these two men were afraid to speak on camera, but said it would be a life time for cubans, earning $20 a month, to buy a car. many are angry with the government. >> i think it is enormously disrespectful. our salaries are not enough to cover personal needs. we've done the numbers, it's expensive. >> driving a car like this is no big deal. for most cubans, it's unattainable. the move to lift restrictions is the latest in a series of economic reforms meant to spark economic growth and get more cubans off the state payroll. with prices so high, most cars will sit unsold on car lots.

despite the freedom, cuban will likely get around the way they have. >> that story and the rest of the news, including much more in the top story of australian authorities, possibly finding debris from the missing malaysian airlines that can all be found on the website. torres here to talk about invocations that can change lives. the intersection of hardware and humanity and we're doing it in a unique way. marita davidson is a biologist specializing inning innings innd evolution. kosta grammatis is an engineer

who designed a buy ontic eye. i'm phil torres, i'm an entomologist. today, technology performance miracles. the suit that's helping paralyzed people walk again. that's our team, now let's do some science. ♪ >> hi guys, welcome to techknow. i'm phil torres and i'm here with kosta and marita. now, scientists are detecting millions of earthquakes around the world. what technology do you study to

help mitigate them? >> here is san francisco's bay bridge. they absorb the areas of the earthquake while leaving the rest of the infrastructure intact. really, really cool. let's check it out. rising from the san francisco bay is the newest architectural jewel of northern california. the new bay bridge, which connects san francisco and oakland, is now open for business. and what a sight it is to see! roughly 280,000 vehicles travel the east and westbound lanes each day. it's now the widest bridge in direction. this is six years worth of round the clock time lapse video of the new 2.2 mile east span.

the project cost $6.4 billion. this is earthquake country. the great san francisco quake of 1906 wiped out 80% of the city. the old bay bridge opened in 1936. and it sits in the worst possible spot: right between two major fault lines. the san andreas and the hayward faults. and the worst-case scenario happened october 17th, 1989. you may remember this scene from the loma prieta quake. a 220 ton section of the old bridge collapsed. traffic came to a halt for over a month. how big of a danger zone is this? >> it's a major one. >> how close are we to one of these faults right now? >> we are very close. the hayward

fault runs right along the hills. >> the bay bridge is a stunning engineering feat for another reason, something that's not visible at first glance. crumble zone technology. until now, crumple zones have been used by cars. they control deformations. the old bridge won't collapse even in a powerful quake, engineers say. marwan was a engineer during the last quake. being. >> if you want to be if a big quake hits? >> the safest place will be on the top of this bridge. it would be one heck of a joy ride but it would be a safe one. >> this is how nadir are

describes this, the engineering community considers this be game changers. the first one is the sheer link beams, inside the 525 foot tower. >> the sheer link beam is the heart and soul of how we made the single tower work. those link beams reduces the there fourses on the bridge. everything is elastic. >> the four legs of the tower move independently. the beams take the energy by bending and deforming. >> the stiffer the structure, the more bridged it is the more forces are applied on it. the more flexible, the less stresses go into it. >> watch your step, watch your pad. things are sticking out. >> we are deep in the bridge's bowels. to get there we have to walk and climb through a mini city of steel. >> you weren't kidding, hmm?

>> we are hundreds of feet under the bay but still under the traffic. >> it's basically a big steel dowel. we have one of those sacrificial elements. >> we are look at one of 20 hinge pipe beams strategically placed inside the bridge. >> in there were an earthquake this would move back and forth like an accordion. by designing sections of the bridge to fail that will protect the more structural elements. after an earthquake workers can go up, inspect them, determine if there is any damage. if there is, it can be cut out and replaced. >> i'm tanning on another innovation, below me are piles, 800 feed in diameter and 300 feet long. there are 360 of them did buried underneath if bay.

>> these are new to bridges but battered piles have long been used on oil rigs in the ocean . think lay horizontally rather than up and down. earthquake crumple technological. >> shake table, it was invented right here at u.c. berkeley and used in 1972. essentially it plows us to recreate any -- allows us to recreate any earthquake that ever happened around the world. it's important because it plows researchers to test structures, bridges and equipment and see how they can withstand earthquake stress. at stanford university, greg credit dearpipeline went to japan to test structures. >> how does the rocking framework?

>> it rocks. by rocking slightly, it can absorb some of the have force he without damage. >> rocking are like the sear link beams in the bridge. can you see the high strength post tension steel cables. the frames get rid of the energy by rock and deforming. civil engineer david marr owns a company, that build the orinda, california if city hall. you can see how the rocking frames are built into the are foundation. >> these cables are the spring and at the base are the steel angle is that shosh the energy. they work together creating the dynamic system of the building. >> how safe is this building?

>> meant to be 25, this 30% stronger than an ordinary building. >> safer than your own house? >> yes, absolutely. >> so the future looks bright and safe in earthquake country. if they can build a safe bridge in the middle of two faults, the safe. >> do you see a day when all new buildings and structures would implement some of this new technology? >> we hope. you would think in cities when a big earthquake comes it would be an inconvenience, rather than a disaster and this rock frame is part of the technology. >> very interesting. what about a place like bolivia where you come from and there's a lot of earthquake risk? >> this is a technology that is costly, fundamentally costly so we can easily apply the to a country like the united states but in a country where i group, in bolivia, it's still pretty out of preach.

if pl la paz was hit with a big earthquake, this is pretty incredible. >> much of our infrastructure is tested and i know they are always iterating and testing technological because they have a lot of earthquakes. >> san francisco has had such serious damage that's cost real lives. >> it's the perfect spot for it phil. the bay bridge is sandwiched through two fault lines. >> as an entomologist, i do like to are work with insects but there's one insect, that i will swat, the mosquito. kosta about. >> the mosquito repellent of the future. i hate them as much as you do. >> we'll look at that coming up.

>> ♪ ♪ ♪ >> hey guys welcome back to techknow. kosta, tell us the story that involves some of your favorite tiny friends. >> not my favorite. mosquitoes, they bother me, they bother a lot of people.

this mosquito repellent is going to change all of that. it makes you invisible to the mosquitoes. let's take a closer look. >> these blood-eating possesses have been called the most dangerous on earth. >> about 3 billion people are affected one way or the other by mosquito-borne diseases. every 30 seconds a child is are dying from malaria. >> dr. michel brown has created an entirely new technology to battle this program. >> how can mosquitoes find us? >> they can use carbon dioxide as their belong sensing mechanism and skin odors to pinpoint your exact location. the running joke is if you want

mosquitoes to bite you anymore, all you have to do is stop breathings. not a popular option. >> so tell me a little bit about where we are right now. >> we are in fact really in a mosquito torture chamber. this entire laboratory was built by i.e. crowd and serves as the epicenter of all our research are activities where amazing things are happening. our technology makes humans invisible to mosquitoes. creates an outer spatial screen around us. >> this is it. a patch, all i have to do is stick it on, i'm invisible to mosquitoes for 48 hours. >> with this machine we're able to directly monitor the mosquito's response to different

chemical formations. >> so this shows you how the mosquito feels about a certain compound. >> exactly. >> let me see if i got this. you got a mosquito slapped down to that slide. you have a needle in its brain. >> through its eye, yes. >> it's sitting there screaming. >> trying to confirm yes. >> but you have got him strapped down. >> double-sided sticky taper. >> you introduce compounds through air. >> uh-huh. >> we know how it works. but does it work? we want to show how good this technology really is. >> right now my hand is untreated with any compound. so right now the mosquitoes are attracted to all the odors coming off my skin as well as some c 02 that is being emitted.

they are probing on the unprotectmesh to try to get on my skin to draw blood. right now my protected hand is in the cage and as you can see they're virtually not able to locate my hand due to the compound. >> dr. mark fry is a professional at ucla's department of integrated are biology, the patch technology is just one approach being developed as we gain a greater understanding of insects attraction to humans. this notion of a chemical cloak of some sort a more effective repellent, how feasible is it? only as feasible we try it. there's going to be glitches along the way. does the cloak wear off? how effective is it? at what concentration? do the animals adapt to it? there are solid answers. we are preparing for alarge

field testing in uganda. we are really exciteabout this. 6.7 million hours of the patch, with real people, one of three districts we'll be testing them, all of which have exceptionally high mal malaria rates, as well as mosquito born diseases. >> ceo amra albana is responsible for this technology in order to get to people who need it most. >> it's very difficult to take new technologies and furnish them into tangible products that were ready for the marketplace. we are excited about it and the promise for the technology but we also knew we had a long way to actually get it ready. in the last 60 years, we haven't really had any break through in technologies that could help in mosquito-borne diseeses diseases.

three and a half years ago we had the potential of saving many, many, many lives around the world. >> this one is definitely getting a lot of attention and so for that reason a lot of entomologists we've been kind of talking about it and we are a bit skeptical but also hopeful. testing it in the lab is quite different than in the field. i'm excited to hear what they get in uganda. >> they have rooms that simulate weather cons in every country. you upload a weather profile, all the different parameters for mosquito life and you can do a rea comprehensive test to see how this mosquito repellent works. the next story i did is a robot called the exo which is

helping paralyzed people walk.

>> hey guys welcome back totech. i'm phil torres and here with kosta and marita. now guys this story i got to do is one of my favorites. helping technology change people's lives. this is a robot that paraplegic people can use to walk again. let's take a look. >> hi! >> this dream happening today. >> these kids from a summer camp near

aspen, colorado is if to give amanda a lifesaving gift. a gift she hasn't been able to do here since she was paralyzed in a horrific accident 21 years ago. >> now i want to invite the kids to have at it and rip into it. >> it is a buy ontic robot called exo. a battery powered external skeleton that gives her body the power to do this: >> are you ready? >> three two one blast off! >> whoa! >> and this. >> i'm walk, you guys! >> and even this! [ crying ] >> the technology is so cutting-edge that amanda is the first person in the united states to own one. >> the moment she stood up, i

was just amazed because she's been sitting down for 21 years! and that first feeling to stand up again, it's just -- i would have been thrilled obe in that position. >> it was an emotional moment for these kids who spent the past year selling countless cups of legal owade and raising are money from generous people to make it happen. >> the first moment, when i stood up and i tried see the children's faces, and some of them, the really little ones, they were just in awe! and then to have that heart to heart hug. and i hugged in a wheelchair, there's a disconnect. i get heart to heart cugz when i stand up. >> -- hugs when i stand up. >> do you promise me a hug? >> yes. >> amanda took her.first steps

to making that a reality in 2010. that's when she got a call from the robot's creators asking her to help them in their technology. she went to the san francisco bay area and took it for a test run. >> how did it feel to be able to stand and look at people? >> first time i stood up, i went home, and i cried hard. in all honesty. these were emotions that i had been dreaming about for so long! and i felt so good in my body. i slept hard. and i wasn't in pain. >> total ending steps. >> 4850. >> 4850! so. >> this is exo's headquarters where the

magic is made and perfected. giving people who are paralyzed a chance to do what they have been told was impossible. >> i feel like the luckiest man alive. >> nathan is one of the robot's inventers. not build for the are meat feed but for the credit military field. >> there's a huge problem in the field for soldiers carrying the large loads, in fact they want to carry more. we were helping to develop exoskeletons. to carry the person's weight and more as well. >> it can be powered by a small battery pack and then there's that whole walking thing. >> it takes over the function of the muscles in your legs.

it can do that either completely, for a person who's completely paralyzed, or partially for someone who is rethroarng walk, like someone who -- credit relearning to walk, like someone who has just had a stroke. >> i put the device in walk-mode and take the first right step and as i move my body the exo will move with me. if i don't move to the any next position the exo stops. >> test pilots like amanda boxtel and jason geezer, how have they helped you advance this technology. >> they have helped tremendously. everything is unpredictable once you introduce a human into the situation. 38 ph.d.es had a different idea how to control something.

without people like amanda and jason we would be at a standstill because we couldn't test anything. >> the robot still has its limitations. right now it can only be used in a rehabilitative setting with a trained physical therapist. then there's the being cost. between $110,000 and $130,000. they hope the food and drug administration can help. >> i don't get enough of these, heart to heart hugs. >> if you need another heart to heart, i'm your man. >> thank you. >> the emotional impact of this is obvious. but are the there other associated health benefits with being able to walk? >> absolutely. all the doctors and all the

patients using this agree, standing up that much, helps how they digest, lowers their pain, and the amount of infections they get. >> can it be used for stroke victims and other applications? >> absolutely. that's one of the approvals they put in for this technology. it's got variable use. one side may be stronger than the other which is perfect for stroke victims because they may have a weaker side and allows them to gradually increase the amount of control they have over it versus the robot. get people on a solid track towards recovery. from earthquakes to mosquitoes to changing people's lives, it's been interesting. join us next week on techknow when we give you more innovations in the field. go deep behind the scenes at

aljazeera.com/techknow. >> a possible clue, australia says it has found two objects in the indian ocean that may be related to the missing malaysian airliner. >> hello, this is al jazeera live from doha. also ahead - gun fire and explosions. bombers attack a police headquarters. >> syrian refugees are getting caught in the crossfire as government for
