violence escalates as israel and hamas bh other for ending the ceasefire s after it began. i'm antonio mora, those stories and much more straight ahead. >> the bombings have resumed in gaza. >> the humanitarian truce over after just a few hours. >> both israel and hamas are blaming each other. >> efforts to broker a more long term truce.

>> it's going to be very hard to put the ceasefire back together against. >> dploams not dead, we've got to -- dploams no diplomacy not dead. >> things are getting better. >> we're not all the way there. >> a syrian army defector testified -- images. law make rs were outraged by the photos. some urged to do more to stop the violence. >> we begin with the war in the middle east. what was supposed to be a 72-hour ceasefire on friday ended about 90 minutes after it started. israel declared the ceasefire over april a israeli soldier was allegedly captured, at a tunnel. >> althoug

another gunman came out and abducted one of our officers. this was the fact. >> while hamas hasn't confirmed capturing golden, the hamas group did claim responsibility for the attack. meanwhile israel responded to the attack on the sigh of rafah. both the u.n. and the u.s. have blamed hamas for ending the ceasefire. defended israel's right to defend itself and said more had to be done to protect palestinians. he said more had to be done to continue the peace talks. >> if we could pause the fighting we might be able to arrive at a formula that spares lives and also ensures israel's security. but it is difficult, we

shouldn't assume otherwise. >> nicole johnston, there were dozens killed in rafah, after israel shelled the city for retaliation for killing the soldiers. >> the fighting there is continuing and overnight it's moved from tank shelling from the israeli side to more air strikes. so we're getting a lot of reports of air strikes on friday, 65 people were killed, already we've had another 20 people killed, so it's been a really hard 12, 18-hour period, inside of rafah in the south. we have been speaking to the people there. they say they're terrified, air strikes and shelling going on for hours. they've received messages from israel telling them not to go outside their houses not to drive, to stay inside. it sounds like a very hard

operation is underway there. ambulance crews haven't been out to get to those houses that have been hit, we know fighting is still continuing and we feel it's a while before we'll get a final death toll there. bodies are still under rubble and a lot more injured people are coming out. it's been difficult for ambulances to get to them. >> what about hamas, has it been shooting its rockets to israel, has it intensified its fighting? >> yes, we've been getting reports that parties are continues to night. i haven't heard as many rockets as i've heard on previous nights but sometimes they're being fired from different areas so you can't always hear them. we haven't had an updated figure on how many rockets have been fired, though. we have heard from the military wing of hamas, about the

reporting missing israeli soldier and we only just had a statement from them. they are saying they don't have any information about the soldier, they don't know exactly what the situation was. but they have confirmed that they had a suicide mission operating near rafah and that as that group was returning, back to rafah, it was hit by an israeli air strike. so the al kasam brigade say they have missed contact with the group, and if they had an israeli prisoner he would have been killed by the air strike. no group has claimed responsibility for capturing the israeli. it's been confusing here about exactly what went on who was involved and whether indeed an israeli soldier is alive inside gaza or not. >> nicole, thank you very much. for more i'm joined from tel aviv

by paul hershan. paul, it's always good to have you with us. hamas said israel are broke the truce when hamas killed two soldiers and captured a senior israeli sore jell. while an israeli soldier had been captured that happened effect. do you have clear evidence that the israeli soldiers were killed after the ceasefire took effect? >> hi, good to be with you. two things. first of all, yes, absolutely it's all there, documented, it's very clear. the ceasefire went into effect at 8:00 a.m. israel time. at 90 minutes later at 9:30 in the morning israel time, the incident happened, it was an attack on our troops. we lost two soldiers, one has apparently been abducted.

the hamas people have put out two contradiction -- well, not necessarily contradicting, two different stories. first one they said was this all happened prior to the ceasefire coming into effect when they understood that it was all cock and bull, because had that happened, there never would have been a ceasefire in the first place. they've subsequent changed the story and actually now what happened they said was they were defending themselves after our troops attacked them. i think you know people will take whatever side they want so perhaps we circulate go and look at what third parties are saying. the united nations has outride condemned hamas more than once today -- outright condemned hamas more than once today. the united states has described it as a barbaric condemnation of the ceasefire. the emir of

kuwait is wiping the spit off his face after hamas put out a signal welcoming the ceasefire. >> there are other signals from hamas after the original statement saying they had abducted the israeli soldier then the hamas people are backing off of that sea saying they may not have it. >> that's right, repeating the pattern they did with gilad shalid, five or six years ago, a little bit more than that. look i don't think anybody is deputy -- disputing it. the secretary-general of the united nations is calling for the return of this young officer. hamas has proved to the whole world, not just to israel, we knew this already already. they have no interest in a ceasefire, no interest in a diplomatic solution. this three-day 72-hour humanitarian ceasefire was meant

to provide a three decor dor to bring humanitarian aid food and three day corridor to bring humanitarian aid, food aid in and medical aid in. this is a school of thought which has now formally elevated a place in society which amounts to nothing more than the worship of death. >> is there a chance there could be some other group not under the control of hamas, including possibly islamicy had where the killing of the so doorstep? >> even if it were we saw in the 12-hour humanitarian ceasefire on sunday last week that hamas has 100% ability to control everything that goes on in the gaza strip. they hold responsibility, they've proven that they can

control what goes on there. and all indications point, in either event directly to hamas. >> now, the humanitarian situation in goos as you mentioned is -- in gaza as you mentioned is dire. many homes destroyed, the decaying bodies in the rubble, in need of food water medication, decent sanitation. thousands of injuries. at first the arab world was much quieter in the past when it came to condemning israeli action. now that's changing. saudi arabia's king abdalla condemned the devastation, there pictures we are seeing from gaza of the suffering are just getting worse. are you concerned that this is going to back fire on israel if -- especially if the offensive intensifies? >> you know, when you use the word concern, i have to say, we're israelis by definition, we're concerned about everything. it's in our

did dna. you mentioned king abdalla of saudi arabia. he did not condemn israel. he condemned the fighting in gaza. he condemned the situation-causing suffering for palestinian people but did he not condemn israel. there is a deep sense of resentment in gaza and in the arab community in the middle east at hamas for what they have done. they have brought down disaster amongst ourselves as well, but directed particularly against the palestinian people, and we're hearing those voices again and again. >> so what happens now? will israel intensify its offensive? and is there any chance now that you'll agree to a ceasefire? >> you know, we've agreed to six or seven i think we're losing count ceasefires.

we've implemented them all, abided by them all. hamas has extinguished this ceasefire. we stopped back, stopped all offensive activities. our troops were on the ground exactly as they were supposed to be. assurances were given by all parties including hamas to the nations. to the secretary of state of the united states. that they would abide by this ceasefire. they don't want a ceasefire. there is a growing consensus around the world. we saw it from the european union a few days ago. we heard it coming out of the american administration a couple of days ago that the time has come to disarm hamas and the other terror organization he, the long term solution to this particular issue in gaza is the did he militarization of the gaza strip. >> paul, thank you for giving us your perspective.

for the palestinian view of the latest development wiementd i'm joined from ramalah. you told the bbc friday there was never a ceasefire to begin with because israel began to fire in rafah before the ceasefire could take effect, one was allegedly captured there. there is ample evidence that all that took place after the ceasefire went into effect. and that does seem to be the international consensus from the united states and the united nations. >> well, regrettably? antonio, the foretold always the u.s. at least in public, would come full support of israeli narrative. israel is engaged in two wars,

first is military war and all have been witnessed and following the devastation ask ask-deaf stakes of that war. you know antonio i am from gaza. i know these neighborhoods, the faces, the families. i have studied these people worked with these people and i know what israel is doing. it's knot even crime against humanity, it is a war against our heritage. and a deliberate targeting of the civilian population because this has been an israeli military doctrine since its inception, kill as many civilians, terrorize as many civilians, target the infrastructure, the electricity, the water. you put pressure practically speaking on the political and military leadership of the palestinians. the second war that is going on is not this lethal and not less voracious which is the war of

spin and the war of pr and the war of lies. part of it the palestinians always initial violence and the poor israelis have the right to different themselves, right to react, which is utterly untrue. the situation today was just an israeli game of deceit to declare that they have received the ceasefire when in fact few minutes before the ceasefire they continued their bombardment of the same neighborhoods from the north to the south and when the ceasefire started they continued their operation at rafah, as i stated at the bbc quoting numbers and they hoped they would manage the pr campaign whereby hamas would be blamed and therefore they will just take further cover by the u.s. by the international community by the international media the ministry media to further slain and slaughter the palestinians. >> what about the mixed signals from hamas? first, the capture of an israeli soldier then other hamas

representatives have backed off. what do you know? >> i don't know of course, i don't represent hamas i'm not in the field, i have no information whatsoever. however as somebody who is following this very closely you know an invading soldier armed to his teeth, committing war crimes right in front of our eyes, against children, women, butchering an entire nation, is hardly the issue. the whole world is up in arms about this soldier that has been captured. america has described this thing as a barbaric act when in fact, the slaying of an entire nation has just been described as israel's right to defend themselves. i think antonio you know i'm sick in my stomach really really, watching this double standard. >> i know you don't represent hamas but you do represent fatah and fatah has been involved in the unity organizations, i know fatah for many years has tried

to negotiate a broader solution, two-state solution for israel. that is not something that hamas has signed onto. are you not concerned hamas's sending all those rockets into israel, in honesty, they have been sending about 100 rockets into israel, truly damaging for a truce in the middle east? >> 80, antonio, we are concerned that the palestinian president mahmoud abbas, the political alternative by secretary of state kerry. mr. kerry came to us last year and he said let's set, let's end this conflict, i will start an initiative and you all have followed what happened. and mr. kerry sat in the u.s. congress and he said that mr. netanyahu, the israeli government has blocked his initiative by continuing building settlements and by choosing the

path of colonization not the path of peace. then president abbas offered another alternative. we brought gaza back to the plfnian national authority, we formed a national unity government, and the first hour mr. netanyahu heard about they went public and he said he objected to this and he declared a war against this government, and to tell you the truth, the first objective of netanyahu's war is a coup detat against the palestinian government. so fatah and the palestinian part has been trying to give political break through out of this. but the current israeli government is blocking every initiative, any possibility is simply because that project is very well-known and very clear to us now. the israeli military doctrine which i spoke about earlier to kill and devastate entire civilians to put pressure on the military and political

leadership on pln palestinians h is covered by a doctrine which is block the emergence of a palestinian state and the main tool to block it is to fragment palestinians in political and geographic terms and fragment the cause of gaza and jerusalem and ramalah, and just came exactly when israel thought it had managed to severe gaza eternally or irreversibly. to focus on the rockets to focus on the symptom, okay, we said the rockets might not be the best way for palestinians to express themselves. tunnels is the creation and the result of the siege. it's been happening for seven years. the people of gaza, the palestinians in gaza created tunnels as an act of dignity for us. to provide for families basic

materials, milk, stuff like that. then some people invested in it and then now it turns military underneath gaza. it has nothing to do with israel itself. seeing the twisted logic and the propaganda braim blaming the vim and seeing israel, a to the narrative, i don't think it will help israeli security and israeli future either. >> thank you for bringing us your perspective. and one programming note. al jazeera america respondent nick schifrin will take the violence behind the deadlines. gaza world at war, airs at 11:00 p.m. friday, saturday and sunday. and now for more stories from around the world. we begin at emory university in atlanta, georgia where doctors

are preparing to treat the two americans infected by the ebola outbreak. emory university is only one of two places in america to treat ebola. specially outfitted airplanes will arrive swiftly one after the next. the outbreak is out of control and that new steps must be taken to contain it. next, we head to washington, d.c. where president obama had stern words for excessive conservative s. >> house republicans as we speak are trying to pass the most extreme and unworkable versions of a bill that they already knowing is going nowhere. that means while they're out on vacation i'm going ohave to make some tough choice -- to have to

make some tough choices to meet the challenge, with or without congress. >> we end in russia and the oval office. president obama called russian president vladimir putin on friday, since the most recent russia. president obama pressed putin about the crisis in ukraine but putin countered by calling the sanction he counterproductive. reports from the kremlin say both presidents obama and putin agreed about the urgency of bringing an end to the fighting in eastern ukraine. at least the lines of communication are still open and that's some of what's happening around the world. coming up. the u.s. economy gets a boost but is the american public feeling its effects, the chairman of the u.s. economic advisors joins us next.

the atrocity in syria what if anything will be done about it. plus our social media producer, hermela aregawi is tracking, what's trending hermella? >> after a woman was bullied about her body on the beach, she fought back on facebook. what do you think? join the conversation

>> the u.s. economy is on a bit of a roll. from wednesday's report that the country's gross dmesk product grew 4% to friday's employment report. the u.s. added 2 are 09,000 jobs last month. at the white house president obama seemed relieved to have something positive to report. >> the good news is the economy clearly is getting stronger. things are getting better. our engines are revving a little bit louder. >> earlier i spoke with one of the president's key economic advisors about the jobs report and where the economy's headed. >> i'm joined by jason ferman,

chairman of the president's council of economic advisors. a little bit below expectations but still healthy growth. the unemployment rate ticked up to 6.2%. you see that as an encouraging number in the statement. >> absolutely. a lot of these bounce around month to month but the most reliable number, total jobs added we've exceeded 200,000 for six straight months that's the first time we've done that in 17 years. the unemployment rate. you look at over the last six months over the last year and it's come down a lot more quickly than anyone expected. as recently as last year, people thought it would take us until 2017 to see an unemployment rate of 6.2%. instead we're there already. you know absolutely there's always more to do. but we're clearly moving in the right direction. and we're starting to move there a little bit faster. >> and do you see the

unemployment rate being up because more people are finally starting to look for work? >> you know i wouldn't ever try ospend too much time trying to interpret one month. i try to look at six months, a year. but what you're looking at july you saw the participation rate go up. people encouraged about the situation job market coming in looking for jobs. many of them finding those jobs but not all of them and that's why the unemployment rate as an arithmetic matter went up in the month of july. >> if you look at job growth over the past few months it's the best we've seen since 2006 but not enough to keep up with population growth or replace all those jobs we lost. how concerned are you that we aren't seeing more job creation? >> i actually disagree with that. it is enough to keep up with population growth. in fact it's enough to run ahead of population growth and that's why a year ago, the unemployment

rate was over 7%. now the unemployment rate is 6.2%. that tells you we actually are running ahead of the growth rate in the workforce. that the participation rate has stabilized since roughly last summer. it would always be good to get more job growth. that's why we would love to work with congress on key steps we could do to achieve that goal like greater investment in our infrastructure. but given where we are demographically right now with slower workforce growth, people retiring as the baby boomers get older, 200,000 jobs a month is enough to bring the unemployment rate down. >> but it's enough if labor participation stays low at nearly historic lows where we are, even though it did edge up a little bit last month. but a lot of the people who are working say they're underemployed and a lot of them have part time jobs when they want full time jobs. >> yeah. we have seen the vast majority

of the jobs created in this recovery, more than 9 out of 10 of those jobs, have been full time jobs. so we've seen a strong full time recovery. the problem is, we saw terrible part time recession. part time jobs went way up in the recession. we're moving in the right direction in that regard. but you're absolutely right, that we have a lot further to go when it comes to everyone who wants full time job being able to have one. >> you were talking earlier about numbers bouncing around. incorporate more so than when it comes to gdp. we saw 4% growth in the second quarter. those were numbers that came out earlier as we saw the economy contract by more than 2% in the first quarter. so do you think the economy is going to start growing faster? because while it has been growing in a slow but steady fashion, it has certainly been below historic lows. below historic averages. >> yes. part of what helped in the --

second quarter was a very strong quarter but it was even stronger in part because of bounce back from the weather in the first quarter, in part because of buildup in the are inventories. i wouldn't expect factors like that to continue but a lot of the broad underlying trends that helped lead to that strengthening, whether it's greater fiscal stability, less of a fiscal contraction, consumers and businesses that are in a better position to spend, i think those are still with us and will help the economy going forward. >> one negative in the big jump in gdp is that equity markets plunged. the dow ended up losing on thursday all of its gains for 2013. and one of fears there because the economy might be getting stronger that the federal reserve will stop its easing policy and raise interest rates, do you think it will stop that and you how soon with it it?

>> i can't decide for the fed, it is something they decide for themselves. markets go up. markets go down. over the longer term our market has grown strongly in recent years. what our focus, though, is on, jobs, the economy, wages and i think if we can help improve all of those that will not only help families, it will also be reflected over time in the market as well. >> now, despite the improvement in the unemployment rate seeing more jobs and people getting back in the job market the gallup polling organization saying consumers taking on the economy has been the worst in the past six months. how do you reconcile all the this? >> you saw consumer confidence at the highest level it's been since the expansion so as the number began -- so there's a number of different measures out there. but fundamentally the way the people see the economy follows what's actually happening in the economy and there's two really important facts about the economy.

it's moving in the right direction. it's moving there at the faster rate but it's not all the way there and even if it was all the way there, we are dealing with decades of stagnating middle class incomes. that's a lot to turn around in a year or two. >> and consumer spending -- consumer sentiment leads to consumer spending which is a big motor of our economy. jason ferman really a pleasure to have you with us. >> good to be here. >> washington saw terribly graphic evidence this week of what might be crimes against humanity by the syrian government. a warning, some of the images may be too graphic for some viewers. a syrian took tens of thousands of pictures of men, women and children tortured and murdered by the sirrian military. the man known only as caesar gave hundreds of thousands of

images of these. stephen rapp is the u.s. ambassador at large for war crimes issues. he leads the state office of global issues. we reported on these horrible photos when the story broke, but you have had a chance to meet with caesar and see many of these images. you told the atlantic council that this is solid images of the kind of machinery of cruel death that we haven't seen frankly since the nazis. what do you say to the syrian government's contention that these photos are a fabrication? >> that is an impossibility and also false. our analysis of these photos is that they are genuine. there are tens of thousands of them depicting thousands of individuals. four or five pictures per person. and having reviewed them, situations, 400 where eyes are gouged out. others where people have had

horrible chemical burns on their bodies. others where people have been cut open, alive. many that have been strangled and quite a number starved. men, women, children, abrought to a military hospital, hospital 601 in damascus, in such great numbers that they had to be stacked up, in the parking places of trucks their being only at that hospital 8 morgue tables. pictures you can see in the distance radio mass in damascus not far from the president's mansion. you can see officers and others bagging the bodies. you can see evidence that's absolutely impossible, it would be easier to fake a moon landing than it would be to fake this kind of evidence. and these are identifiable individuals.

i mean people i met this afternoon, identified people that had been their students, people that had been their neighbors, individuals that were relatives. this is the story of real human beings. stage out in the dead of night. their families hoping they had been returned. in the past many detain ees had been returned after torture, the signal not to oppose the uniquelyregime,and the governme. >> i can only imagine what you've seen. you said they show a level of systemic atrocities, that clearly implicate syrian officials including president assad. >> 24 of them including some major ones in the damascus area where these individuals come from they have carved into their bodies the numbers of those facilities, facilities like 215

and 216 that can be identified by security services that ran them. and we know who commands those operations. other documents that have been gathered on our documentation efforts give us some indication of people being sent and the orders that were made to send them there. and those that have responsibility up and down the chain. and clearly this kind of conduct reaches right to the top. the regime doesn't do this without a decision at the very top. >> what does the world do? many more people are dying in syria than in gaza. the white house didn't go after syria more forcefully after assad used chemical weapons against his people. we've only provided minimal support, will there be impunity for these mass atrocities? >> there won't be impunity for the mass atrocities. proposal is there to the

congress for a substantial $500,000 of assistance to the opposition that we hope will be approved and will begin to change the playing field there. but in the meantime my particular responsibility is mass atrocities. i prosecuted those responsible for the rwanda genocide and for the horrendous atrocities committed in west africa and sierra leon leone i had to connect the dots, through shad ohy groups to presidential palaces. here you have it in the institutions of the state. >> one of your war time prosecutors say countries

aiding syria could be implicate. russia and china have vetoed any war crimes trials against syrian officials. we heard never again in kosovo, rwanda and czar darfur. what kind of inact hold those meaningless? >> we hold others to account and when individuals like rios mont in gaw gawt guatemala, 24 years after his crimes, there comes a day of reckoning. it's not easy. it's not easy when you're talking about sovereign states with powerful allies. but the world has changed in the last 20 years. and we're working to identify these individuals that have been

tortured and killed and if they're dual nationals, our country or other countries, there can be third country prosecutions of those responsible, those who gave the orders for the torture, those who are commanders of these particular camps or prisons or detention facilities. national prosecutions can't reach the chief of state of a foreign country but they can reach a lot of powerful people. >> ambassador stephen rapp we efforts. thank you for being with us. >> good to be with you tony. >> time to see what's trending on the webb, hermella. >> bully shaming, a mother of five's message to beach goers. whether suntanning at the beach, two guys and a girl were pointing laughing and make fun of her body. so she came home and wrote this open letter to them on her facebook page. i'm sorry that my first attempt in sun bathing

in a bikini in public grossed you out. i'm sorry that my belly is covered in stretch marks. but as i look add your quote unquote perfect body, i can't help but wonder, what incredible feat has your body done? she's amazed at her comment's support. >> maybe if they get bully shaming, they'll be less likely to be bullies. >> good for tannis. in that light, straight ahead, accusations of an overly sexualized culture for ohio state's marching band, reignites the debate over what constitutes

hazing. chimpanzees are more like humans than we ever realized. and later, star trek comes to life. >> i'm joie chen, i'm the host of america tonight, we're revolutionary because we're going back to doing best of storytelling. we have an ouportunity to really reach out and really talk to voices that we haven't heard before... i think al jazeera america is a watershed moment for american journalism >> now available, the new al jazeea america mobile news app. get our exclusive in depth, reporting when you want it. a global perspective wherever you are. the major headlines in context. mashable says... you'll never miss the latest news >> they will continue looking for survivors... >> the potential for energy production is huge... >> no noise, no clutter, just real reporting. the new al jazeera america mobile app, available for your apple and android mobile device. download it now

>> at what point goes an organization's culture and traditions cross the line into hazing and harassment? ohio state university's marching band director was fired, against a culture of hazing. if the environment was so hostile, why have thousands of people including band members and band alumni rallied to his defense? joining us from indianapolis, indiana, is hank newar, author of several books, hazingprevention dork .org created the hank newar award. the long standing culture of the band was highly sexualized, that it facilitated sexual harassment, that among other things, the band director would

monitor and witness a yearly event called the midnight rant where band members would march into the school stadium in underwear, even naked. if all this is true why are we seeing this backlash with so many people supporting him? >> well, as with the football program if you've got a winning program and this is called the best damn band in the land, you have a lot of people supporting and you have a lot of people who are in favor of these kind of traditions seeing them as either harmless, beneficial or a way of bonding all the band members together. >> now all of the students and alumni of the band have said that they were never forced to do anything or they weren't mocked for opting out of things they were uncomfortable with. but thousands of dollars have been raised to help this man. one of the allegedly harassed students a young witness named jubes because she was jewish and

had large breasts has come out to support him. don't realize they're being hazed. if that's the case how are they being hurt? >> well, the whole idea is that it's a culture that did can lead to biggerrer things. elizabeth allen last done a study at the university of maine that has linked possible sexual assaults that come out of it. the idea is that not all of the perpetrators are the same, not even one can keep things within bounds like that. you do hazing, long enough, and you're going to have a serious incident. a lot of them started off as harmless pranks and you wouldn't have thought they would have escalated into a death. >> i want to talk about that in a minute. but let's stick to ohio state for a minute. the band director was apparently working to improve matters. did the school have too choice here though? didid they have to take action to avoid losing federal funds?

>> we are talking about title ix here. the possibility of the lawsuit might have worried them. the possibility of two cheering coach and two assistant coaches were fired for inappropriately touching and other types of things but before that the president gordon gee who was asked to leave by the university was involved in a whole series of scandals and the board of trustees came down not only on the cheering coaches but on other presidents but, the inkind of inappropriate behavior. >> issues of hazing and bullying have been very publicized over recent years. you said we have seen deadly incidents involving fraternities, we've seen hazing

death and beating on a bus, recently a fraternity at the university of akron was penalized. the acts go on and on. why are we still seeing so many cases especially in our top institutions? >> we've got an instance of group-think where camaraderie is more important than anything. the idea of being accepted, the idea of having a challenge, the idea of going through a rite of panch that is bigger -- passage that is bigger than you and more compelling than you. is appealing to college students. >> leading to issues and concerns among parents across the country. hank newar, thank you for your perspective on these things. >> thank you, antonio. >> a new rover planned for red planet that can produce oxygen

and fuel is going to cost a large fortune. is it worth it? but first chimpanzees as fashion mavens? >> on tech know, >> scientists go up in the sky, >> we're flying over a fracking field in texas >> using ground breaking technology to check air quality down below. >> formaldehyde levels were astronomical...it's bad. >> tech know, every saturday go where science meets humanity. >> this is some of the best driving i've every done, even though i can't see. >> tech know. >> we're here in the vortex. only on al jazeera america.

>> today's data dive goes ape. new research finds chimpanzees are foodies. a journalist followed them around for several weeks.

chimps do the same for good fruit. researchers discovered they passed on trees with sparse or lesser quality fruit closer to home for ones they visited before that had better food. sometimes the tastier trees were 80 minutes away. it shows that the chimps also have tremendous memories. they'd swing to their trees long before they could possibly smell the fruit. once they feasted the apes let out grunts of pleasure. this is recent of some studies showing similarities between humans and apes. announcing like humans chimps get their intelligence through a combination of their genes and environment. part nature, part nurture. there is a great deal of evidence showing apes are capable of sophisticated communication. have been taught sign language and can operate keyboards with

sign language on them. the findings of a researcher spent eight years with 18 wild chimps in uganda. they used 66 gestures to intentionally communicate 19 meanings. and in june, the journal animal cognition published a study showing chimps can create and follow their own fashion trends. research ers observed a chimp named julie suddenly put a piece of grass in her ear. her son did the same and others in her group did the same, positioning the grass in the same way julie did, and they kept it up, even after julie passed away. let's hope that doesn't continue in the human world. coming of the fence are

you on? borderland, tomorrow at 9 eastern, only on al jazeera america. >> it's the week of the rover on the red planet. the opportunity rover has now hit a grand total of 25 miles over its ten years on mars. the longest distance traveled on another planetary body. a surprising accomplishment considering the rover was originally designed to move less than a mile and nasa revealed the rover the future, a program that would make oxygen from carbon

dioxide, and could help visitors to mars breathe and to make rocket fuel for their trip home. we're joined by derrick pitts. an al jazeera america contributor. derrick, glad to see you. this opportunity rover has continued to operate far beyond expectations. it's really the energizer bunny of space exploration. >> it really is a remarkable machine. the original mission length for that rover and its sister rover, there were two of them opportunity and spirit launched in 2004. they were originally expected to only really run about three months, maybe six months, if everything worked out well. they've been going for ten years. and it's only about a year and a half ago that spirit finally stopped operating. but the opportunity rover is still going. not as well as it could, earlier, but it's still doing good science. >> and what can we expect to get from it?

what kind of good science can we get in the future? >> well, the things that those two rovers were meant to do at the outset of their mission was to be able to identify once and for all that water really had been present on mars in some quantity in the distant past. boasboth of those rovers in different locations on the planet definitely identify that there had been plenty of water on mars. that was a very, very important discovery because we weren't sure at all that there had been water and large amounts of it. now what they can continue to do is identify environments where they can could see rocks created in a watery environment and try to determine how many kinds of water-originating minerals were found ofte on mars. this is what we need to know about the planet as a whole. those two have covered only small portion he of the planet

although one has gone 25 miles. >> nasa has revealed plans for one that cost $1.9 billion, they will launch it in 2020. it is a rover on steroids that will be crucial for any future mars exploration. >> oh absolutely yeah, there's no question about it. and the reason why is because this new rover in 2020 is going to do a different job from what the current rover on the surface is doing. the rover is there now is sent to identify environments that might have been conducive thought development of life but the rover in 2020's intent will be to actually look for life signals. to look for any kind of evidence that there really was life on the planet at one time or maybe there's life there now. so the instruments that will be used on the new rover, how can we say, beefed up versions of the rover that's there now and in many ways it will have to

look like a mciver and a bear gryllis all wrapped in one to find whatever evidence it needs to find now. >> and also create oxygen and fuel both of which will be necessary if humans ever manage to go to mars. finally let's talk about this advancement in tractor beams. science fiction fans know about them now there's a big advancement, beams that can move matter. >> well let's not get too far ahead of ourselves. the amount of change that has taken place over time that we're trying to do this actually has expanded dramatically. the first tries at moving anything, with any sort of tractor idea, was only about a thousand times thinner than the width of a human hair. so that's not very much different. but the most recent efforts have

gotten us about half an inch of movement. but the real question about this antonio is what is the force being used to do this? how much energy is required to make it happen and is it something that can turn into a reality in the future. the technology that has most recently bee been advanced that has given us this half inch of movement is acoustic energy to give it a push forward. and it's almost like we're used a targeted or focused vacuum beam right at a target that would allow pressure behind it to push the target towards us through this vacuum. the only question is how much energy is it going to require to do something like this on a grand scale? half inch isn't much but if we want to drag spacecraft across the gulfs of space we'll need it. >> derrick, thank you. that's all for now. the conversation continues.

>> welcome to the news hour. coming up in the next 60 minutes. israel continues to launch attacks on gaza but allows some refugees to return home. attempts to stop the fighting takes another blow as israel said it will not attend talks in israel. >> in west african leaders catastrophic consequence
