good evening. this is al jazeera america. >> this can't happen any more. this can't happen in america and it can't happen here new information on the arrest of eight oregon militia members, the death of another and the efforts underway to get the rest to surrender. striking a deal in ferguson, fed ram and local authorities announce-- federal and local authorities announce a plan.

>> as the situation unfolds, we want to be prepared defeating i.s.i.l. in libya. the approach the u.s. military might take there as i.s.i.l. gets stronger and its attacks more devastating. >> the goal is to really put space into the hands of teachers so that they can share that with kids restarting an old n.a.s.a. mission. the push to get teachers back into space we begin with the moves to put an end to the armed occupation of a federal wildlife refuge in oregon. agents have sealed off the compound in an effort to force the remaining protesters out. their leader ammon bundy was arrested last night. he urged them to abandon the cause and go home.

the latest from our correspondent. this seems to be a pretty big change of tune from ammon bundy now that he is in custody. >> reporter: absolutely. for weeks we have been watching the governor, the f.b.i., the sheriff tell these occupiers that they needed to get out and go home. today it was ammon bundy telling his followers the same thing. what impact it has had we're not sure. there have been reports in local media that several of the high profile people left at the refuge. we have been watching the occasional live stream from the refuge where five people say they are still there and intend to stay there. lots of big developments in the last 24 hours, but what is clear is it is not wrapped up just yet law enforcement tightens the

perimeter with road blocks set up on the few approaches to the isolated wildlife refuge headquarters. eight people are now in custody, seven in oregon and another in arizona, all facing at least one felony charge. >> it is the actions and choices that has led us to where we are today. they had ample opportunity to leave the refuge peacefully and as the f.b.i. and our partners have clearly demonstrated, actions are not without consequences. >> reporter: one of those consequences the death of lavoy finicum shot in a confrontation with police. he was among those who gave us our first tour of the occupied property and first hint of the determination behind the protest >> you feel something in here about what's going on? >> i do. there's emotion, a fire that burns inside that's hard for me to not speak out, not to stand

up. it's right in the heart strings >> reporter: he emerged early as a leader and spokesman for the group, clearly add mired by others. lavoy finicum also had a keen keen sense of the theater of the moment >> if they want to serve the warrant, here i am, right here. i'm going to make my bed right here. they can come serve it right here. i love the free air. >> reporter: on this night with a rifle and a sleeping bag promising to camp out and wait for authorities. >> reporter: what ends this peacefully? >> the federal government goes home. they have strict responsibilities spelled out in the constitution. they're not to reach down into every level of the states and the county and regulate every aspect of our lives >> reporter: do you expect gunfire? >> if they want to pull the trigger it's up to them >> reporter: authorities haven't given any details on how he was killed when shots were fired during the arrests on tuesday. here is how one of the occupiers

who claimed to be in a different vehicle in the same convoy described it in a facebook post: >> he went after them. he charged them. he was very passionate about what he was doing up here. not dismissing what they did or what he did >> reporter: these two leaders of the take over and five others arrested in the burns area were arraigned in federal court in portland. behind the new roadblocks, those remaining at the headquarters have been asked again to leave. >> we don't arm up and rebel. we work through the appropriate channels. this can't happen any more. this can't happen in america and it can't happen here. thank you. >> reporter: big cheers for him with that statement. now, the investigation into exactly what happened in the officer-involved shooting which led to the death of lavoy finicum is being handled by a special team from a county just

to the west of here. they are not commenting at all by in progress in that investigation. we've also learned that the f.b.i. has requested the faa put a no fly zone in the wildlife refuge right over the area where that headquarters is where those few remaining occupiers are holding out. that no fly zone is in place now thank you for that. today the city of ferg son, a year has passed since the protest. our correspondent reports the tentative seeks to prevent arrests and safeguard the civil rights of residents >> reporter: the city here needed to get this agreement in place or risk being sued by the department of justice and that could have resulted in millions of dollars worth of fines.

the city has been under fire for the last 17 months for the way it handled the michael brown shiting - shall shooting for the way it handled protests after that shooting and also the way it has handled african-americans in the community over the last several years. some of the highlights of the agreement include the expanded use of body cameras. all police and jailors who come into contact with the public must be wearing a camera. enhanced police training. police also must document the use of force and only use it when necessary. they also must improve court services and that would include an online mechanism for paying fines. the city said it worked long and hard on this agreement. in the statement it says: over the next month the city will be holding a series of public meetings so that the

community can comment the wife of a police officer who committed suicide last year is now facing money laundering charges. he staged his own death as a murder in september sparking a huge manhunt. investigators later said he had stolen money from a police youth program. the prosecutor said his wife was in on the scheme. she denies the charges. if found guilty she could face up to seven years behind bars. two new reports accuse the warrior project of lavish spending. the veterans fund wasted money. the project took in more than 370 million dollars in dough medications last year. the year before it spent only about 60% of its income on veterans. the pentagon is drawing up plans for a new front against i.s.i.l. this time in libya.

the chairman of the joint chiefs of staff says if the president approves the plan operations could begin within weeks. our correspondent reports from the pentagon. >> reporter: pentagon sources say the u.s. is already applying for spy planes over libya and have had special operations on the ground as it gathers more intelligence about how and where i.s.i.l. is operating. it all appears to be a prelude to a campaign and perhaps even putting some u.s. come bottle boots on the ground-- wombat boots-- combat boots. >> reporter: the result of an i.s.i.l. result here last week, a series of recent assaults on libya's oil infrastructure. in a video released by i.s.i.l. a fighter vows more attacks on more libyan oil fields in the coming days. it's just one sign of i.s.i.l.'s growing strength in libya. by one estimate, the group now

controls a 150 amile stretch of coastline, an oil rich part of libya. the spread of i.s.i.l. in libya has kicked u.s. military planning into high gear >> we're looking at military options, a range of other options as a government, that we can engage in to try and - as the situation libya unfolds, we want to be prepared as the department of defense always wants to be prepared in the event that i.s.i.l. in libya becomes more of a threat than it is even today. >> reporter: sources say the options include air strikes from the u.s. from the sea. it will include u.s. commander raids, like raids conducted in iraq and syria and the u.s. operation in 2014 that nabbed the prime suspect in the 2012

attack that left u.s. ambassador chris stevens and three other americans dead. the u.s. was forced to acknowledge that about 20 special u.s. forces were north-western briefly last month. after the libyan air forces posted their picture on facebook. the american officers left after being ordered off the air base by local forces. it was part of an effort to find local fighters in libya, the u.s. can support, much like similar efforts in syria and iraq. >> there was a small group there to meet diverse range of groups to get a better sense of what is happening on the ground. >> reporter: a meeting last week indicated a decision on expanding the fight against i.s.i.l. in libya will probably come in weeks. it's fair to say we're looking to say decisive military action:

>> reporter: the idea is to build a fire wall of sorts around i.s.i.l. to keep it contained while libya ates unit government tries to establish itself. right now there is no functioning government in libya and that makes a strategy problematic at best thank you. still ahead on al jazeera, researchers have found what may be a primary cause of schizophrenia, how the discovery could potentially lead to new treatments for the disorder. also the governor of michigan lays out his plan to deal with the poisoned water in flint.

>> we tend to band together, so we have a voice.

>> we're just surviving. it's really hard. teams in flint michigan are going door to door handing out water bottles as a temporary solution to help people. today rick snyder laid out his plan for a more permanent fix. the governor has appointed a group of experts to tackle the problem. >> so there's a number of steps we're taking, but this is just the beginning. >> reporter: more than 20 days after activating the national guard to aid in the water crisis, the governor has named a

field of experts to over see a long-term fix. among the 17 people selected a virginia professor and a flint pediatrician who helped uncover led contamination in the city's water. >> so i am focused on the solution here. we're going to address this problem and i'm committed to doing that. >> reporter: during the news conference are flint mayor, the governor said that the short-term goal is to recoat surface pipes that are leaching led. in addition to providing bottled water and filters there is also a request to the federal government to expands medicaid health care to the young who have made been ex-poached to contamination-- exposed to contamination. >> i have told the governor snyder that flint residents should not have to pay for water they did not and are not using. >> reporter: the state is also facing more pressure over the crisis.

the american civil liberties union and others, including flint resident, melbourne aise amays, are asking the-- melissa mays are asking for the immediate replacement of pipes >> what happened to my family, what my children will go through for the rest of their lives should not have happened. it should not happen to anyone else, the pain my kids feel should never be felt by another child or adult or senior citizen in this great lake state. >> reporter: do you think that race has a play in what is going on here in flint? >> inherently so. it's mainly african american. this is race and class. it's about poor people being held in contempt >> reporter: we spoke with civil rights activists who described it as a disaster zone >> reporter: what is your take on the state's response to this disaster? >> it's typical. it's a cover up because now the

lights are on and everyone is running for a hole. >> reporter: the governor has apologised for the failure in flint but puts much of the blame on the environmental sector. it is unclear how long the crisis will last. with no end in sight, the uncertainty weighs heavily on those who call flint home scientists studying schizophrenia say they have made a discovery that could lead to possible break throughs in treatment. they pin down on how certain genes could trigger the condition and affect brain function. researchers say finding the mechanism that causes schizophrenia could help them to detect and treat it. harvard associate genetics associate steven mccarroll who led the research team. congratulations on the

discovery. i was surprised to read that more than 2 million americans have schizophrenia. until your study, we didn't know why those changes in the brain were happening >> that's right. it has been a mystery for thousands of years, really, why schizophrenia arises and how it arises and even at a time in medicine where enormous progress has been made over the last 20 or 30 years in finding new drugs for cancer and cardiovascular illness, there has not been equivalent or even similar progress for illnesses of the brain and it's because we don't know the basic things about why they start so what you discovered is a gene, the c 4a gene that that is a culprit that leads to this pruning that goes awrite in young people's brains. >>-- awry

>> that's right. pruning is something that happens to all of us in our teens and 20s. particularly pronounced in the parts of the brain that manage complex information and help us interpret and think about the world that we're in, but it seems like somehow in some people that normal developmental process goes awry and become too intense or too prolonged. we need to continue to work to understand all the components of why that happens you think that this gene is the main culprit, but it wouldn't be the only cause. >> that's right. so our understanding today is that there are almost certainly many genetic and environmental influences on schizophrenia and, indeed, on another disease, and a discovery like this is

important for ililluminating what the underlying biology is, but you don't want to look to any one gene and say that will be the cause, that is one of the reasons we feel strongly that people should not be thinking about testing for this gene. the point of the gene is to find the biology that's driving the illness we currently have drugs to deal with the effects of schizophrenia. could this lead to coming up with treatments that could prevent it all together? >> sadly today we actually don't have drugs that address all of the components of schizophrenia. we have drugs that address one symptom of schizophrenia. which is the symptom of psychosis. but schizophrenia patients also endure agonising cognitive decline, emotional withdrawal from friends and family. there are a lot of things happening in the brain in schizophrenia that are not addressed by the drugs that we have today. that's why it's important to find the root causes of schizophrenia so that drugs

could be addressed to the root causes and, thereby, address all of the symptoms of schizophrenia and not just one how soon do you think we could see better treatment? >> it takes years to develop medicines that are safe and effective, but there are a few reasons to be possible here. one is that these compliment proteins have been studied for decades for their roles in the immune system. scientists know about them. one never knows about the timeline, but one can be more hopeful than if this were a completely novel gene that no-one had ever thought about before it's fascinating and we wish you the best of luck in moving forward on this. harvard professor, pleasure to have you with us >> thank you years after the challenger disaster ended n.a.s.a.'s teacher in space program, the program continues here on earth

with teachers inspiring students.

a federal appeals court heard arguments today over whether a trans gender teenager should be allowed to use his boys toilet in the school. the 16-year-old was born a girl

but identified as a boy. the court will look at whether bathroom restrictions for trans gender students. 30 years since the challenger took for take off and died. the disaster ended n.a.s.a.'s efforts to put teachers in space. now a nonprofit group is keeping the spirit of the program alive. we're shown how it is inspiring children to pursue science. >> three, two, one and lift off. >> reporter: when the challenger was lost 30 years ago. my god. there has been an explosion >> reporter: so were the hopes of a generation of future explorers. you never gave up on the dream? >> no. i never have. i'm still needing to get up in

space >> reporter: you still hope to get into space >> right. i'm getting old but it still could happen. do you see the icon for the balloon? >> reporter: as a young teacher he was one of thousands who applied for a seat on challenger. part of a bold new idea to launch students' imaginations by putting teachers in space >> it's not often that a teacher is lost for words >> reporter: like this who was supposed to be the first >> if a teacher can do it, why can't i? >> reporter: the idea largely disappeared after that january day in 1986. >> that ended that program, that it was seen as not worth the risk, that it was meant to inspire people, not to upset them. >> reporter: new now hope. >> a state-of-the-art space craft. >> reporter: with private companies trying to go beyond our planet. this woman says it's a new opportunity. she leads a nonprofit called

teachers in space. it started in 2006 to continue the original challenger mission. >> the goal is to really put space into the hands of teachers so that they can share that with kids. so we want students to be excited about space careers and to see space careers as real and attainable. >> so this connector, right, connects to these: >> reporter: they do that with lessons and experiments to encourage students to pursue science and technology >> once released this balloon will go 60,000 feet into the air. it is more than just a fun science experiment. it is a chance to inspire kids to reach for the stars >> reporter: the school's main focus, even though he still trains and hopes to launch, he knows his true legacy will be his students >> when you go up what do you want to be? >> an astronomer.

i just want to learn more about the plants and their moons and how far it is from where i am, like right now. >> reporte >> reporter: she is only 11 and leading an experiment to see if moss can grow in the ztratosfear. >> if you want to do something, keep at it. keep at it and don't let anybody or anything slow you down. >> reporter: so your teacher inspired you to say that? >> yes. i think he is the inspiration. >> reporter: all these decades later, the true goal still stands. >> i'm going to be taking you to a field trip. >> reporter: it goes further, even if you never leave the ground thanks for joining us for the latest news any time you can head over to aljazeera.com.

ray suarez is up next with the inside story. have a great night. great night. >> oh, the republican candidates for president are against current abortion laws in one way or another. but simply being against the procedure is hardly enough to get your ticket punched. on this edition of the program, we'll bring you the story of carly fiorina, who collected a paycheck from a company who produced vaccines from fetal cells, cells that come from terminated pregnancies, anding thus a hotly contested law with ethics. with
