to our website, aljazeera.com/americatonight. we'll have more of our program tomorrow. this is al jazeera america, i'm thomas drayton in new york. let's get you caught up on the top stories. protesters in hong kong defies an order to clear the streets as a new work week begins. >> we have seen understandable concern. >> officials try to overcome fears in relation to ebola, but admit more cases in america is possible. we look at past endemics, and whether america is ready to deal with a crisis.

polls are cast in the brazilian election. we have the latest on the tight race. and why the u.s. is hoping to use elephants for life-saving work. >> now, as we take you o hong kong lie, it is 10 o'clock. hong kong's chief will take all actions necessary to make sure schools and government offices open. despite the warning many protesters filled the streets of a night - but not as many as we have seen in the past several days. everything appears to be peaceful. adrian brown joins us from hong kong. it is monday morning, dead line day, what is happening on the

ground? >> we are approaching the busiest part of the week. behind me the offices warned, told the protesters, this they wanted the area cleared by the morning of monday. it has not happened. protesters are encamped here refusing to leave. and they expect the police to use tear gas, rubber bullets, to clear the area. there's a hard core of student protesters that remain, but the majority left the site. also important to recap why the students are here. they want the right to choose the next leader. china said you can do that, but we'll choose who the candidates will be. that's what the protest is about, that began nine days ago. >> i sense we are approaching

divisions in the student ranks. they are weary, and they have been - there have been appeals from leaders and politicians of all sides for the student to stop their action before there is violence. they say you have made your point, you have international attention, it's not worth dying for. >> has beijing given an indication that it will begin talks with the protesters? >> we had a hopeful sign when representatives of a group met officials of the government to talk about a framework for negotiations. they don't seem to have gotten anywhere. i don't think i'm holding out much hope. what we'll see in the next 48 hours is an effort to clear the encampment, not just cy leung's office, but the complex

nearby. to the left of me is the main barracks for the people's liberation army in hong kong. there are 6,000 chinese troops stationed here. many pray they could be used to end the movement. >> possibly with force. university officials - are they saying anything about the protests comprovide mainly of students? >> yes. the vice-chancellor issued an emotional plea on sunday saying it was time for the student to pull back from the brink before it's too late. other academics said it's time for the student to go back to the classroom. a lot of students have been not going to class for almost two weeks, a big sacrifice for students in hong kong the question is whether they'll heed

the appeals. at home, it was a week ago that thomas eric duncan became the first person in the united states to be diagnosed with ebola. they are not planning, but they are say to stop it. >> it's a good thing to see concerns. so that we don't miss a patient. >> diane eastabrook joining us in dallas. what have we heard about duncan's condition, how he's being cared for? >> duncan is in critical condition. the c.d.c. says he's tonight fighting for his life. the liberian man's condition is a huge concern for dallas's liberian community.

many say they have lost loved ones back home to ebola. at the church in dallas, liberia parishioners lifted their spirits with song and prayed the deadly virus decimating their homeland will not do the same here. the current ebola outbreak in west africa sickened more than 7,000 people, killing half. the first u.s. case was diagnosed in dallas last week. before that ebola has touched many here in one way or another. this daughter lost her daughter to the disease and worries about her grandchildren. a doctor lost two former colleagues. >> because of the heat, you are sweating, most likely use the hand to wipe the face or something like that then you

unknowingly transfer the virus. >> with tears, it's hoped that the families back home will be spared. >> there 3,000 marine in our country helping. they are there helping us. that is a sign that the international community are not forgetting us. >> many here hope the prayers will soon be answered. >> there is another meeting going on. the community association is trying to educate the president about what is going on here and try to elate fears. >> an emotional time for many. >> the cameraman that attracted ebola. they are on their way back. they left on an airplane a few hours ago. he is headed to a medical center in omaha.

the 23-year-old has been working for the past three years when he got sick. >> he is the fourth american to have contracted the disease whilst working in liberia. >> the doctor is now back in the hospital. doctor richard sacra appears to have a respiratory infection. he has been placed in isolation as a precaution. his immune system was probably lowered during his battle with ebola. >> 60 members of the kentucky air national guard are headed to west africa to help in the effort to fight ebola. they'll serve in senna gal and help assemble a cargo pub. they are signed to the 123rd contingency response group and will remain in place as long as they are needed. >> here is what we do. america is a place and a people relied upon to help. the guys are dying to do that.

they are here to help the focus and brothers and sisters in africa. >> officials say the airmany shouldn't have contact with anyone that could be carrying the virus. we invite you to join us and focus on whether the united states is prepared on an epidemic of any sort. that's in "the week ahead". . >> a number of i.s.i.l. targets have been hit in the past this hours in iraq and syria. air streaks north-west destroyed a large unit. further east, near al-maya dean two rifles were hit and destroyed. across the border near the city of fallujah. despite the air strikes. the group managed to fight its way to the outskirts of a nearby town near fallujah. i.s.i.l. fighters took obvious part of a hill overlooking the up to of

kobani. kurdish forces are holding the line. i.s.i.l. attacks are spreading the the border into turkey. we have more from the border. >> turkish authorities evacuated residents and the media from the border area with kobani, because i.s.i.l. fighters seized a hill. they are shelling the town. some of the shells, stray shells have been falling on turkish soil. a family was injured when a shell hit the house, not far from when the media recorded event in kobani. as the vehicles leave, military vehicles go in to kobani. military forces, a significant presence along the border. while it is happening, the leader of the main syrian kurdish party, he's been in ankara meeting the turkish officials. we don't know what happened in the meeting, the subject of the

meeting, but what has to be on the agenda is how the kurd will defend kobani from the advancing i.s.i.l. forces. >> bernard smith reporting from turkey. government forces clashed with fighters, 50 miles north of baghdad. the government-run television station showed footage of troops fighting i.s.i.l. government forces were able to capture the city. the fighting with i.s.i.l. led to precautions at mosques in iraq. muslims began celebrations for eid. the holiday lasting three cause. it commemorates how the profit was willing to sacrifice his son to god. muslims who had to flee their homes are struggling to find normalcy during the eid holiday. we have this report from erbil. eid is the celebration for young and old. it's especially enjoyed by children. the holiday is a time for

present and brand new clothes. this man says ace children are happy. they -- says his children are happy. they think they are on a trip. he hasn't told them the truth. they lost everything when they ran from the i.s.i.l. fighters. they are one of 250 families living in a refugee camp in erbil. >> back home we are worldly people, look how we are living here, it's updignified. we have to other choice. >> he has set up a store. much to his regret the camp is likely to become a permanent home. the city is one of the oldest in the world. it has seen waves of migration, and now thousands of people are coming here looking for protection. a truckload of meat arrives in the camp. a gift from a wealthy emeraty. providing a chance for families

to enjoy a family meal, a highlight of eid. >> the camp has gone quiet, and most women are inside the tents, we'll go inside and see what they are preparing. thank you so much. >> translation: we need protection. we need to get rid of those terrorists, our conditions will drastically improve once we go home. >> children's blow up balloons to decorate the tent. parties are not in a party mood. the stress is weighing on their shoulders, as well as the burping question - when -- burn question - when will they be able to return home. >> vice president joe biden apologised again for remarks made about coalition partners. he apologised to the prince of the emirates saying he didn't mean to implay they were fund --

implying they were funding groups like al qaeda. he apologised to turkey for the same allegations. polls in brazil are closed, and results are in. mexican authorities are investigating the discovery of a mass grave, which some fear may be connect to the disappearance of dozens of students last week. >> tokyo's 13 million resident face for typhoon fan funning stay with us.

welcome back. president obama appeared at the opening of the veteran's monument in washington. the americans veterans disabled for life memorial honours soldiers disabled in the line of duty. wherever you were, whatever your story is the moment that binds each of you forever. the moment that realisation in life would not be the same.

>> the memorial is designed around a star-shaped fountain with a ceremonial flame, reflecting pool and four sculptures. tragic fews - a u.s. airman is dead after tropical storm phanfone washed them away. typhoon phanfone is carrying wind of up to 90 miles per hour. okayan ou weigh is home to half of the american troops in japan. >> kevin corriveau is joining us, what are they up against? >> they are looking at winds, power outages, flooding. japan handles this well. we were talking about a super typhoon. when the system went through okayan oua. let's look at the satellite image as the systems makes its way to the north-east.

making landfall to the south-west of tokyo. the storm is beginning to fall apart. i believe it will come out if the next hours. it will be downgraded to a tropical storm. this is the 18th storm that we sa seen in the western pacific. it's an active season here. i want to take you to the eastern pacific. i want to show you simon, a category 1 storm. it made its way, and we saw rain storms. they are still dealing with the clean-up ests and the repair efforts were going on. this is the path we think we'll see. it's going into more water, it will drop to a storm and tropical depression. if you remember, any system coming into the united states, it will bring a lot of flooding

and a lot of flooding over the last couple of weeks. we are looking at the temperatures in the north and the north-east. take a look at chicago, here in new york. we are looking at 56 degrees, it will be cooling in new england, where we talk about freeze warnings and frost advisories. tomorrow morning the temperature will drop to the 30s, and towards the border states we'll see 32, 33 degrees, that's why we are looking at a problem. 70 degrees. >> it's a little early to crank up the heat. >> i did as well. thanks. a mass grave has been found not far from where 43 mexican students disappear. it's not clear if the two incidents are related. we have more if mexico with adam raney. >> reporter: this is where a series of mass graves have been unearthed outside the town of

iguala. forensic experts have been called in to exhume the graves, and they'll test to see if the graves are the 43 students missing for more than a week. the graves are a few kilometres from the spot where the students were last seen. government officials are unable to confirm the identities of the bodies. >> translation: it would be irresponsible of me as the head of the office to say it's connected to the students. with information we have, we can establish the location of the graves. we know that they have human remains. i reiterate, we have to wait to see what the experts find when it comes to genetic forensics. a member of the human rights commission told al jazeera the bodies were burned and appeared to have been buried. after being criticized for not doing enough, the federal government is taking over the investigation which had been in

the hands of state officials. >> translation: the mexican state cannot permit an indignant incident to go unpunished. we'll put all the forces of the state to shed light on this unfortunate event. >> reporter: the bodies were found in an area where other mass graves have been found before. guerrero state is a poor area of mexico. families have been calling on the government to do more for the past week. >> after the governor announced the discovery of the graves, classmates arrived here in the state capital, throwing rocks, molotov cocktails and flipped over a car, a sign of anger and frustration with what they say has been government inaction in the case. brazil's presidential election will be decided in a run off election. dilma rousseff won most of the votes, but fell short of a victory. 142 million people took part in

the polls. sao paulo was the one with more. dilma rousseff is the favourite in the run off. >> she probably is, because she got 41% of the voters, which is more than the nearest rival. aecio neves had 33. dilma rousseff has a big party restrooucture behind her, and the workers party. i would say most analysts would say she is feeling good. also they pulled good numbers as well. he'll pull together a wider coalition to challenge tierra ruffin-pratt in the run off. they are feeling confident. how do you explain the lead in the face of a bad economy in brazil. >> well, it's really unemployment. unemployment is low in brazil.

it's 5%, and i think lower than the united states. even though growth rates in brazil are less than 1%, the economy is a technical recession, dilma rousseff is doing well. people are working in brazil. the other issue is she's really been the candidate to keep the social programmes, social welfare programs in brazil. benefitting people. those two factors, 41%, have gone out and voted. they are supporting her strongly. a lot of international eyes on this. the u.s. and brazil had rocky relations after the spying allegations. has anything really changed? >> well, i can tell you in the last year or so since the revelations came out, that behind the scenes diplomatically there has been a lot of back door talks between the united

states and brazil. i spoke to dilma rousseff a couple of months ago and asked her about this. she said she has been receiving calls in the past from vice president joe biden. the u.s. and dilma rousseff in brazil want to work out a better relations between the two countries. it's in both countries. as far as this election is concerned. whether it be dilma rousseff elected on october 26th, both have said they want good relations with the u.s. days of cancelling state visits is what dilma rousseff did when she cancelled a state visit to the united states. probably in the past both sides were trying to patch things off. both countries need each other. economically and politically. south america and the world super power and in both

country's interests, it was to try to find a way forward. time to focus on the run off. thank you. brazil is not the only south american that held elections. they cast ballots for regional and state obstacles. there's more than 12,000 officials. where candidates are alleged to have ties. in bull garia citizens voted in the second election. the center right party are set to win. a senior member of the socialist party calls it a disappointing defeat. having moons and access to a great education doesn't always guarantee you entry to a top university. that's the focus on "edge of 18," the documentary series about the journeys of young adults. >> since i was 12 i basically

have been trying to get the best grades i can, the best test scores i can. every film i entered and won, and i thought i've got this, and i didn't. why? what did i do. >> some of our kids come from affluent backgrounds, and the problem may be that they can't fulfil their ambition for one reason or another. but they have the resources to do so if they chose. my parents invested in private schooling since third grade, all the way up to 12th grade. all with the intent of getting into a top university, and they invested a lot of money. >> we are not doing enough to make opportunity possible for the children. that is one consistent theme. it breaks your heart at times to see kids who are intelligent, motivated, and want to make a better life for themselves and

their families. and they can't do it. other kids - there's one kid who is undocumented woman from arizona. >> i really need help to may for my tuition. i am writing in regard to a personal matter. i'm looking for someone with a kind heart willing to help me fundally education or offer a loan with fair interest rates. if you are a good students... >> they care about community. and you are undocumented, it doesn't matter. for me, it's upsetting. actually, it's more than upsetting. it's really sad. >> senior prom is coming up. hurry and purchase your tickets. i'll twerk on the dance floor. you know how i do it. >> we are learning to live with a new set of valuation. >> acceptance of the gay and lesbian community. for the parents of one of the kids in the show, it presents enormous challenges.

who is the girl follow you in the prom? the girl follow you in the prom. a boy. for me, you not born gay, don't tell me that story. i know you. i know you. don't tell me you worn gay. a new episode of "edge of 18" airs tonight. coming up, how prepared it the united states for an epidemic. find out what the country is doing to contain ebola and other diseases. an announcement on hugh lard pack ard. an announcement on the way.

welcome back to al jazeera america, here are the top stories we are following. it's monday morning in hong kong. protests have subsided. civil quarters returned to government headquarters.

some demonstrators are camped out, defying a deadline to clear the streets. brazil's presidential election will be decided in a run-off. dilma rousseff ran most of the votes, falling short of a majority. facing aecio neves in the run-off for the 142 million that took part in the polls. u.s. health officials are struggling to calmle public's -- calm the public's fear of ebola. thomas eric duncan became the first and only person diagnosed with the disease in this country. he remains in critical condition. >> it's sunday night, time for a look at "the week ahead". the spread of ebola in west africa overwhelmed hospitals. in the past week the virus appeared here, with the first patient diagnosed on u.s. soil in dallas texas. how his case is handled raises a lot of questions. is the u.s. prepared for ebola, and how will the country deal with a crisis or epidemic down the line. this report with heal.

academics are part of history. two struck. the spanish flue pandemic killing 50 million worldwide. more american soldiers died from the flu during those years than killed in combat during world war i. through mid-century the spread of measles killed one out of every three or four infected until the development of a vaccine. fast toward to today, and the suspicions of ebola in question is raising questions about endemics and containment. >> ebola is scary disease because of the severity of illness and we are hoping for the recovery of this individual. at the same time we are stopping it in its tracks in this country. >> reporter: the c.d.c. has protocols in place. first, it's essential to diagnose knew cases and equally

important to distribute supplies, medicines and vaccines, and quarantine those sick. the focus of ebola races a question - how prepared is the u.s. when it comes to fighting the epidemic. it raises a red flag with a report warning the reduced financial resources. the losses make it difficult for state and local health departments to expand their preparedness capability. congressional funding for health preparedness shrunk by $1 billion, since the height of funding during the 2001 anthrax attacks. state and local departments cut 50,000 jobs since the 2008 crisis. as if to prove the warnings, many have been flown across the country. c.d.c. confirmed 500 cases of the d68 entero virus strain in more than 50 states.

>> the man that discovered ebola in the 19 '70s, dr peter pei at said in an interview the biggest infectious disease threat for america is the flu. 200,000 americans are sent to the hospital. over a 30 year period, up to 50,000 died because of complications from it. to fight the spread of ebola, the u.s. is sending 600 troops to the region, there's 200 on the ground. the new arrivals provide engineering and logistical support. with the possibility of the disease spreading at home, the u.s. focussed on preparation. it's not the first time health officials had to bolster offenses. they faced other threats from s.a.r.s. in 2003 to m.e.r.s. last year, and the swin flu h1 n 1. they have fuelled calls for funding on research, approaches and containment. for more i want to bring in a senior associate at the upmc

center for health security in pittsburgh. good to have you with us. >> thank you for having me. >> america is hearing about the infectious diseases. many are simply nervous. what should be the level of concern? >> infectious disease has been a threat to humankind throughout the history, whether it's ebola, s.a.r.s., avian flu, there's a disease that is emerging, infecting disease. we live in a world populated by microbes. it's not surprising to see new diseases on the horizon, it's something that americans should be concerned about because they are a major threat to health. >> are we prepared for a national medical crisis. >> there's a lot of steps to prepare the country for a major epidemic or pandemic. as you mentioned earlier, anthrax spurred a lot of

investments in terms of vaccines, antivirals, c.d.c. funding, hospital preparedness, all of that flowing in the 2001 attacks, making the country more prepared than it has been. there are some erosions in the games that we made. there's always going to be a wishlist of things making us more prepared than currently. >> you bring up a good point. is there enough drugs on hand to handle an endeming? >> depend on which drug. there's a lot of flu virus, but i worry about m.e.r.s. or s.a.r.s., something we have none for. so there are dangers from having unknown viruses emerge. it's what a lot of investors have spurned. they are looking at the diseases

on the radar. they are making sure we have a pipeline when we are ready. we saw it with ebola. in 2001, it was not on anyone's rick, but the bush administration thought of it as a bioterrorist risk and all the antivirals are the fruits of those labours. >> i want to bring in dr alexander gaza, professor in epidemiology joining us from st. louis. i want to talk about an opinion that you had the in "new york times". the response needs to be more intensive. to you feel the government is doing enough? >> i do at this time. it's important for us to stay on alert as well. so even though i think we are a little slow to ramp up, i believe it's on the radar screen for everyone now. there's more steps to be taken, and tom from the c.d.c. was adamant about looking for all

options and not limiting anything. >> are there factors in determining how severe an epidemic will be? >> there is. one is transmissibility. i think that's where a lot of talk about an epidemic of ebola coming to the united states really does not pass that test. it is still a difficult virus to pass between people. but the other one is leethality, which ebola meets, a high case fatality rate, which is what drives a lot of fears distroupding the virus -- surrounding the virus. >> do all hospitals have infectious disease specialists on hand ? >> most do. in major metropolitan areas, almost every hospital has an infectious disease specialist on staff. when you get to the rural hospitals, you run into challenges of recruiting specialists such as infetchous disease -- infectious disease

staff. >> where do we stand on the vaccination rates in the us? >> it's high. it's slipping away because of the anti-vaccine movement that causes doubt. we see resurgence of diseases of things that we had not heard of. that's a threat to public health. when people refrain from getting vaccinated, and we have controversy over the influenza. we are not where we need to be. we have a high rate. especially amongst health care workers and pregnant women. i want to talk about funding. is there enough funding to tackle the emergencies. >> i do believe there's a lot of federal funding, but there's a lot of things on the wishlist that we haven't had funding for. there are a lot of concerns. lots of local health department don't have a capacity to process the data and have individuals to

go out and do what we are talking about. they are at risk because of funding cuts. >> good risks. fighting ebola mean knowing what you are up again, getting funding for research is not always easy. science and technology correspondent jacob ward has more on them. >> zoonomic diseases pass from animals to humans. six out of 10 diseases that infect humans originate in animals. anthrax, dengue fever and ebola. >> the difficulty is they require analysis to get out ahead of them.

you have to say there's one bat, it may have one disease in it. you test of the hypothesis, it's true or not. that's how funding works in the united states. the national institute of health likes that proposal. i'll investigate one species, for one inspection. the problem is there are simply far too many zoo nottic potential infectious diseases for an investigator to be that lucky. researchers try to use a systems approach. a data investigation in which they look at the infectious diseases in all species of an animal. the difficulty, and this is part of why we have a hard time getting out in front of things, and get surprised by diseases like ebola, is it's hard for a scientist to convince federal authorities to give them the money for a fishing tripe in terms of -- fishing trip in terms of reach. we need to take the era of big

data, moving it into the science, but how science is funded in the future. >> talking more about that - how do you stay one step ahead of the next medical health crisis? >> it's tough. your report was spot on. it's tough to get funding for things that have not happened yet. traditionally congress funds in a rehabilitationry manner instead of a proactive manner. so you see when crisis come up, it's easy to get funding for it once the crisis occurred much it's tough, especially in times of sequester and limited budgets to get funding for things that you think will be a problem in the future, and you need to work on now. so it's very tough to convince a confident official to convince funding makers, fund makers and lawmakers that these are important things to focus on and spend money on. >> talking about the infectious diseases, do we need a federal

health database to track ebola, where travellers have been. >> data can be used for good. having a database of contacts, using it on the ground, is something that would be useful to public health officials. they are used to using low tech approaches, going out with a pen or paper, but a high tech approach makes their job easier, making our health better. >> at what point are travel restrictions necessary. do they take action? >> travel is difficult. it runs the risk of isolating a country and making the disease harder to fight at the source. when you prevent people coming out, you restrict people coming in and and do a lot of damage to the economy. in the case of ebola, right now the economies are threatened by the disease. they are losing a lot of g.d.p.

and a lot of lives there, and to further isolate them may put them on the verge of collapse. >> how concerned should we be with entero virus. we had a 4-year-old recently die in new jersey. >> we should be concerned about entero virus. it's proved formidable. we have not seen this virus croup up -- crop up in decades. now it's come back in a virulent form. it's taken the life of a young child in new jersey. not only that, there are case studies of muscle weakness and poral sis associated with the virus, that the c.d.c. is investigating. we have not written the chapter, and it's important to stay out the front of this as well.

>> there are many strains, up to 100. >> correct, but they are different entero virus strains. we are focused on the d68 strain. >> what can we expect for the upcoming flu season? >> it depends. sometimes it can be a crap shoot. the c.d.c. does a lot of work looking into the southern hemisphere where you get the samples from. they have the summer, the winter and the flu flip-flops. they take the prevalent strains from the southern hemisphere to develop the vaccine for the northern hemisphere. so far there hasn't been strains we have seen or developed a vaccine for. as we have seen in the past, with h1 n 1, sometimes there are strains that can come up and surprise you. >> i know a lot of people scratching this - you talk about

ebola, entero virus and the flu season. how do you know which is which when you deal with a medical emergency? >> well, it's hart when you have mult -- hard when you have multiple outraids, and you can ming about middle east respiratory system, in the middle east right now. it underscores the fact that you need astute clinicians and hospitals diagnosing these things at the point of contact. that's the holy grail, rapid diagnostics discerning different viruses quickly and direct treatment based on the test. we are a way aways from that. that's a goal that infectious disease persons have wanted for a long time. >> that's assuming people seek medical attention. in final moments i'll give each of you a couple of moments. what needs to change when dealing with infectious diseases in. >> i think there's a couple of

things, first, there needs to be adequate funding. second, there needs to be education, not just education about the scary ones like ebola, but common ones like influenza, and third, every year you have an opportunity to be vaccinated against a large killer of infectious disease, and that's influenza. >> final thoughts? >> i share dr gaza's sentiments. all the gapes we have seen in life span and civilisation progresses is due to the control of infectious diseases, an attorney-general said we closed the book on infectious disease, but we will not. we life in a world of mib robes, there'll be threats, people have to realise they are important, they have to be vac signated, and integrate this into their thoughts about their own health. >> senior advisor at the health

clinic, and sociology and professor of epidemiology thank you both for joining us on "the week ahead". before we go, let's look at some of the other events coming up in "the week ahead". monday - the supreme court in session. cases range from free speech on the internet. wednesday - minnesota vikings adrian peterson appearing in court on child abuse charges. indicted by a grand jury after whipping his 4-year-old son to discipline him. friday - the winner of the nobel peace prize will be announced in oslo. nobel laureates have been planning a summit. they cancelled after the south african government refused to give the dalai lama a visa. coming up, a major announcement by hewlett packard.

and the investigation into a fire at the 9/11 memorial complex in pennsylvania. >> immigrants trying train to become doctors - what they promise so give the u.s. in return. >> mitch has been in there so long. >> while others want to stay the course. >> all the way mitch! you know exactly what these people needs in kentucky. >> communities trying to cope. what does the future hold? >> the economy, the struggling coal industry and healthcare are all impacting their vote. >> "america votes 2014 / fed up in kentucky". all next week. only on al jazeera america.

in south africa the u.s. army is studying whether elephants can help them detect explosives. it may sound lake an unusual task -- sound like an unusual tack, but it turns out they are top dog when it comes to a sense of smell. tania page with more from south africa. >> reporter: elephants can find water under ground and sense electricity. they have long memories and an extraordinary sense of smell, more sensitive than a dog. that is why stephen lee is here, the u.s. military chief science officer. he's here to seek out a combat related question from nature. shaun thinks he can hep.

in a bucket is a small amount of explosives. the bull will signal when he has found it. >> thatta boy. >> lee believes he can design a machine to replicate the elephants drunk, that can save lives. >> for the soldier, you can see chemical agent detectors. biological, and those types of technologies can go to the commercial market for the medical environment, sensing if people are sick, sensing industrial waste, monitoring the environment. >> it's a proud day for him. the elephant's sense of smell is 14 times more powerful than a dogs. >> another area where the elephant excels is in memory. while dogs may need to be trained once a week in a test like this, these elephants haven't done this for an i can't remember, and they are getting it right every time. >> this runs in the hensman

brothers blood, elephants run. dad was followed by a heard of wild elephants in the zambezi valley. they picked up his scent and they tracked him. dad came home, and taught them to track scent and used them to try to stop poaching. >> the u.n.'s chief scientist says within 30 years he could have a machine based on their unique trunk and their talent. researchers say african elephants have twice as many genes as those that dogs do. one of the founding fathers of silicon valley, hewlett pak art is planning to separate. hp plans to separate computer and printers from corporate services. it could announce the change on
