that they end up with the skills that they need to lead fulfilled and empowered lives. >> julia gillard, thank you very much for being on "talk to al jazeera." >> thank you very much. . >> this is al jazeera america. live from new york city. i'm tony harris with a look at today's top stories. the diplomatic push is on. secretary of state john kerry rounding up allies against the islamic state group. and in the wake of disaster homeowners' lie on di --homeowners rely on federal disaster funds. how do they cope when the feds want their money back?

>> secretary of state john kerry lobbied turkey today to join the international coalition aimed at destroying the islamic state group in iraq and syria. kerry pushed turkish leaders to join the fight against is. something that they've been reluctant to do publicly. but kerry said that turkey is committed to fighting terrorists. >> turkey and the united states will stand together against ail challenges in the region including all terrorism. within the coalition there are many ways that turkey can help in this effort, and we will continue our conversations with our military and other experts spending time to define the specific role that turkey will play. >> meanwhile, the c.i.a. believes the islamic state group may have more than 31,000 fighters. al jazeera's jamal al shayal looks at how the group has been able to recruit so many.

>> reporter: they're well armed and well financed across northern syria and iraq. but it's their brutality that has made them notorious worldwide. now america intelligence agency says the group known as the islamic state is growing. michellely their numbers are estimated around 10,000. but now the c.i.a. say 30,000 could be fighting under their banner. there appears to be little agreement and clarity as to how and why the i.s. group has grown so quickly. >> you do have to address those root causes, the disenfranchis

disenfranchisement of the sunnies and iraq and there is a rouge reason why many of theme have gone over to isis. you have the same thing in north africa, syria, and throughout the middle east. >> reporter: another view is that the so-called islamic state group is that it arose as a result of the iraq's government failure to be more inclusive, alienating the sunni of the country. hundreds of protesters were killed, prime minister nouri al-maliki maintained what he called terrorists were among the demonstrators. but within months the islamic state emerged in those very same towns and cities. >> the root problem in iraq is the issue that has to be addressed. with the previous iraqi government under prime minister al maliki the sunnies and the

kurds felt disenfranchised, and fact they were. prime minister al abadi now says with the new government it will be inclusive. this will be a challenge to get the sunni tribes in iraq first to trust the new central government. >> reporter: but the i.s. reach is not limited to iraq and now extends into syria. for now it appears the international powers have failed to come up with a plan to combat the group's presence in syria. many fear dealing with the i.s. group solely from a military perspective will only create similar movements in the future. al jazeera. >> germany said it will join the fight against the islamic state group but it will not participate in airstrikes. it is already providing military aid to kurdish fighters. today the defense military announced it will send more weapons to iraq and will send 40 paratroopers to iraq on how to train fighters and how to use

the equipment. the turkish government has not embraced plans by the u.s. or middle east nations. >> reporter: secretary kerries kerryy's trip ha, announced $500 million, and secretary kerry and u.s. officials trying to remind people that that is a huge issue at the same time dealing with the islamic state group militarily, and when it comes to turkey, that means its border. so many of the foreign fighters who have flown into the islamic

state has pushed hard. it has denied entry of a thousand suspected foreign fighters, but no one is under the delusionment that it can be closed completely because turkey is not able to publicly endorse this plan. it's holding 49 turkish diplomats and it is worried if it endorses the plan the fate of those diplomats will be the same as the fate of the american journalist who is have been beheaded by the islamic state group. privately turkey is being cooperative and being very aggressive against the islamic state group and they are expecting that that border will get closed in the next few weeks, if not even sooner than that, but it is very difficult. kerry is on a mission to create an oh global coalition, some of

whose members are enemies, especially in the middle east. the u.s. is a long way away of convincing not only the military but the political strategy to defeat the islamic state group once and for all. >> enjoying the military campaign highlights it's uniqu uniquely difficult position. bernard smith has our report. >> reporter: this might still be turkish soil but this is a border town that looks to the middle east. it's a place of pilgrimage, a supposed birthplace of abraham, one of islam's great prophets. now sometimes mingling among the pilgrims a man with different intentions. they're close to the end of a journey that will take them into syria and iraq to fight with the group it calls itself the islamic state. but turkey has made that final leg much harder.

>> the plain ahead is syria. this smuggler tells me it used to be easy to get there. you just cut a hole through the border fence. not any more. >> the changes began ten months ago. turkish border has put tanks there and even shot at people. now it's much hard for get foreigners across. >> reporter: since january aspiring fighters have been trying to cross the border anywhere east of the euphrates river. raqqa province just across the border. of course turkey does not want the fighting spilling over here. the turkish government fears playing an active campaign to

push back i.s. forces could result in i.s. taking revenge on its hostages. it hosts hundreds if not thousands of syrians escaping from the fighting. >> the people are tired. the islamic state took everything and controls everything inside the city. there is no money, no work. >> reporter: u.s. officials have said they understand turkey's unique position as the only muslim majority country in nato. but being so close to the conflict it's discrete cooperation is viewed as essential if the campaign against the islamic state group is to have any chance at success. bernard smith, al jazeera, turkey. >> the australian government has raised its threat level for the first time ever. prime minister tony abbott said there is no information to

suggest that an attack is imminent. it's threat level is now at high. it's the second-highest level since the scale was introduced back in 2003. fy any's military chief said that the commander made the right decision when he surrendered to the al nusra front in golan heights. the 45 peace kee keepers were released after being kidnapped two weeks ago. there is suggestion that they were unprepared when kidnapped by the rebel fighters. a theory thatf fijians deny. the army announced it has ten men belonging to the taliban in custody. it comes after malala was shot in the head and neck and shoulders in 2012. she was targeted for campaigning to educate girls in that

country. and dangerous rail cars shipping oil, the green group says some of the cars in use are decades old and lack safeguards needed to prevent accidents. lisa stark for us at the white house. how significant is this lawsuit? >> reporter: it was filed by the sierra club and another group called earth justice. if the judge agrees, it could put pressure on the department of transportation to ban these rail cars. now the department of transportation does not agree that these rail cars are a problem, but they have safety rules that would phase them out over a number of years. environmental groups say the government is simply acting not aggressively enough, not quickly enough. >> fred mallar is a man on a mission. mallar and others have been sounding the alarm about freight

trains carrying crude oil. they can stretch 100 cars long. when there is a problem this can happen. >> is there an acceptable level of derailment. >> there has been a huge spike of crud that is more flammable than other types of crud. the oil industry disputes that, but with shipment skyrocketing, so have accidents. an accident in alabama. a near disaster in philadelphia, and then april in lynchburg, virginia, right downtown. >> never in my life. it was scary. >> reporter: as most tragically in canada last summer, 47 people died when a runaway crude oil train derailed in a tiny town in québec.

there is widespread agreement that safety standards have not kept pace so the government is drawing up what it calls comprehensive new safety rules. among the proposals, stronger tank cars, better breaking systems, slower speeds for trains with older model cars, safer rowing and better notification to stay on train shipments. safety advocates say this does not go far enough. phasing out the older rail cars, for example, would take two years. >> i call them pepsi cans on wheels. safety boards have been issuing alarms about these rail cars for 21 years. >> reporter: there is no prior notification of local fire and police when these trains role through. the railroads say the secrecy is necessary for security. safety groups disagree. >> there is not one city in the country, not one citizen in the country that has been told what the railroad decisions are for

the routing of the most dangerous cargo. >> reporter: the industry points out all shipments arrive in safety. but all are wrangling over new standards and how safe is safe enough. now the department of transportation declined to comment on this new lawsuit. the rail cars are one of the issues, but it's only part of the puzzle. that's why there is comprehensive safety proposal out there. tony, they're accepting public comments on that proposal until the end of the month. >> lisa stark for us. thank you. new sanctions against russia despite a tenuous cease-fire. the u.s. and european union are targeting everything from the countries' economy to its defense and the kremlin is threatening of retaliation including closings air space to the west.

>> reporter: white house officials call all sanctions significant and said they would have an huge impact. but outside they dismiss that. that's not what is being said of these sanctions. from now on any american company or american who wants to long-term debt coul wants to finance through these banks has been limited to 30. the u.s. believes the biggest impact that's going to be oil exploration, something that the u.s. feels it has the corner on the expertise. american companies have two weeks to unwind any contracts they have helping russia with oil exploration. officials are betting this time those sanctions might impact russians' thinking. they admit so far they haven't. >> so the sanctions announced against russia could take a bite out of u.s. companies that do

business with the russians, including exxonmobil. real money's ali velshi joins us. ali good to see you. how will these sanctions impact exxonmobil. >> we talk about natural gas that goes from russia to europe. that's fine. natural gas is a small bees of russian economy. oil is a huge piece of russian economy, and like the u.s. it goes offshore to get oil. the offshore in russia is in the arctic and only europe and america has the technology. they have the engineers, scientists, rigs and equipment. now these new sanctions with five-state owned russian defense companies are extended to oil companies. there is a big deal between the russian-own oil company and ex-monday mobile.

you are probably heavily invested in exxonmobil. it is in every fund. they started looking at the law that has been decided this afternoon. they stand to make billions of dollars with the state-owned energy companies, and they can't do that. this is going to have a major impact. exxonmobil is a country that has gone out of its way to see these sanctions against russia won't work. they've called the world petroleum congress, and they seem to be thumbing their nose at these sanctions and at the united states, which to some people may think is a little

patriotic after making so much money here. >> so little business has been done in the arctic really, but the stock and the company have been counting on the ref news that are coming in from this partnership in coming years. there may be an impact on stockholders, and americans should think about this? well, that all depends. most of us are holders of the exxonmobil stock, but if they were to say maybe that's not the best thing to actively work against the interests of your company. you know how people work, money talks louder than work. >> what else are you working on? >> we're talking about companies who are racing groceries to your door steps.

start ups that are attracting millions of dollars. do you remember when we were younger men, this was a big thing, the beginning of the tech boom. and so we'll see how this works. >> ali velshi, "real money" at the top of the hours. thanks, ali. what happens when the government wants you to pay back the disaster money you have already spent. many people in that situation after the super storm sandy.

>> nearly two years after super storm sandy crashed into the northeast thousands of residents are being told they must repay the government for grants they received in the aftermath. but for a lot of folks that money is long gone. roxana saberi is with us now. she talked to one new jersey homeowner who was told how much, thousands of dollars. >> reporter: thousands of dollars, tony. he got this letter in july asking him to return $26,000 in grant money. the letter came from the state of new jersey, which told me it's trying to get back $1 million in all. they say the money should never have been paid out in the first place. but the money is long gone. >> this is going to be a deck with a railing.

>> after two years ted is still repairing his home in long branch, new jersey, damaged in super storm sandy. he said he'll be paying back bills for years. now new jersey said he owes money that it had given him in the format of a grant. >> it helped to determine the cause of repairing the home. ted got a letter saying he was eligible for the grant. the state took the cost of repairing the home, subtractinged insurance payments in loans and gave $26,000. >> this is what it's asking for back for the date of this letter. i've never received a letter like this from minute asking for any kind of money. >> reporter: the letter said cost estimates changed. >> they say they're trying to protect taxpayer's money and they're afraid of fraud. is there any possibility that

you maybe spent money you didn't need to. >> no. not a penny, no. we spent more than what we received. >> and $26,000 grant they gave you, what did you spend it on? >> what we're standing on, new floor, new siding, new deck outside. new walls. sheet rock, anything that was not covered, a lot of it that was not covered by flood insurance. >> reporter: it's not just happening in new jersey. new york and fema are also going after homeowners. some have paid but many are fighting back. >> it's not in anybody's interest for the federal government to seek repayment from someone who simply doesn't have the funds to repay it. >> reporter: ted said he does not have the money either. >> this is refrustrating. we don't know what will happen if we don't pay it back. we don't understand why we should pay it back. >> reporter: ted has reached out to the state several times and

he has not heard back. the state he paid too much and he has got insurance payments. >> as it is in most of these cases. appreciate it. thank you. you know the latest jobs report, the national unemployment rates among blacks is double the rate than whites. but in new orleans live to this. a staggering 52% of black men are unemployed. jonathan martin reports on how the city's mayor plans to change that. >> brian carter has not had a job in nearly a year. he's 27 with two kids. >> i want to impress my children more than anything. working is a priority in my life. >> david diaz is also unemployed. he returned to new orleans this summer after serving 12 years in

prison for armed robbery. >> i'm a changed person. i'm a changed man. i'm eagle for work. >> both men are being trained in ca car pen try. 52% of working age men here are jobless. >> that is not an acceptable number for a lot of different reasons. first of all, it's unjust. secondly, it doesn't do anything but actually pull the entire economy of the city down. >> many of the men face common obstacles, lack of education, criminal history, and employer discrimination. so the city is trying to get men who want to work connected to specific jobs. >> we have job training centers, but sometimes people train for jobs that don't exist. what we're doing in new orleans is making sure all the investments we're making, the opportunities for young men here that don't have jobs. >> they're partnering, the water

board, for example, will team with a local college to offer training a for hundreds of jobs as it overalls it's crumbles infrastructure. and all of those institutions who should be hiring around there, they say i would love to, we don't know who they are, we would love to, but they need training, we want to get rid of all th the buts. >> not all black men are the same. some of us really do want to work. >> reporter: after six more weeks of training he hopes to be working full time, no longer a part of the statistic. jonathan martin, al jazeera, new orleans. >> a problem bigger than football. that's what one football hall of famer describes the scandal rain

rice. >> and now a controversial mayor is calling it quits. those stories and more coming up on al jazeera america

>> a new episode of the ground breaking series, edge of eighteen >> just because your pregnant don't mean your life's ended. >> intense pressure... >> i don't know if this whole dance thing will work out. >> tough realities... >> we chicago ch-iraq, because we have more killings... >> life changing moments... >> shut the camera.... >> from oscar winning director, alex gibney, a hard hitting look at the real issues facing american teens. the incredible journey continues...

on the edge of eighteen only on all jazeera america >> so questions are mounting of the nfl in the ray rice case. michael yves is here with more on developments. >> developments and questions and all of which, tony, have led to the league hiring a former fbi director robert moller to conduct an independent investigation of the nfl and it's handling of the case. that process is ongoing with no timetable for completion. that's something that could be said for the saga now facing the league and ray rice. >> ever since national football

league commissioner roger goodell went on cbs news and said no one at the league had seen the video from inside the elevator of ray rice hitting his wife janay, the league has side of multiple reports caller for investigation of what the nfl did know of the incident before issuing a two-game suspension to the running back. espn's report that rice himself told the commissioner he struck his wife in the face. the league's credibility is facing serious questions. today the nfl confirming rice's indefinitel indefinite suspension. quote: >> the union has three days to inform the league whether it

intends to appeal on rice's behalf. on thursday night raven's game against the bits bits steelers several ravens fans showed support of ray rice including female fans. >> i don't believe in abuse, but she struck him first and any woman who can hit a man can be hit back. that's my belief. while the league and people around the country debate what is appropriate punishment for rice, many tried to give perspective on an issue that goes far beyond football. >> this is bigger than football. there has been wide rag widespread outrage showing what happened in th the elevator in the casino. but could we direct that outrage

and address the cries of so many women and do something about it look ongoing comprehensive education of men of what healthy, respectful manhood is all about. this is another call to men to stand up and take responsibility for their thoughts, their words, their deeds, and as deon says, to give help or get help because our silence is deafening. >> reporter: deion sanders, former informal players now one of james brown's co-host. he does bring up a good point. as advocates o against domestic violence, this is prevalent around the country and not just involving professional athletes. >> this was always going to get headlines. this is a high profile athlete, but is this athlete being judged similarly to similar cases.

>> if you compare it to the specifics of rice's incident to that of u.s. district judge mark fuller in alabama, you could make the argument that fuller's assault on his wife was more prolonged and more brutal. according to the details of the police report, the judge dragged his wife by the hair, kicking her and bunching her in the face, leaving her bleeding from the mouth and forehead. now they both received options to avoid jail time yet fuller is does not seem to be receiving any professional punishment. judge fuller admits laying hands on his wife during the course of the altercation but nothing in the incident disqualifies him from being a federal judge. that's in stark contrast who say ray rice should not have been suspended.

and some people say he should never play begin. >> the hits keep coming to to the league. >> yes. >> and adrian peterson, the star running back for the minnesota vehiclings. >> we have multiple media reports saying that the texas grand jury had indicted peterson on charge of reckless injury to a child. while peterson's son was visiting him at his texas home before the season started, peterson used a switch to discipline him. for those of you not familiar, a switch is a thin, flimsy branch taken off a tree which can leave cuts or welts on the skin. after returning to minnesota his mother noticed the marks on him, took him to the doctor and notified child protective services back in texas. the irony here is last year adrian peterson's two-year-old son by a different mother was

killed through child abuse by the man the child's mother was dating at the time. >> that's right. what a week for the nfl. >> it's a bad pr week for the league. they need to circle the wagon, as they say, and fix this pr. >> yes, a couple of others, one more sports item here. the general manager of the atlantic hawks is taking an indefinite leave of absence after making racially charged comments. on a conference call danny feiri who played in the league said that free agent luol deng had a little african in him. what does that mean, and he could be disruptive in the locker room. there have been calls for ferry being fired. in south africa oscar pistorious has been charged of manslaughter. the judge said a he was reckless

in the shooting of his girlfriend. he is now free on bail but will likely face jail time when sentenced next month. in today's power politics, 53 days until the midterm elections and democrats running for office have all but declared war on the conservative billion mayor koch brothers. david shuster joins us now. >> yes, tony, now they have the numbers as to why they should be so upset. charles and david koch have long made it clear they will do everything they can to help republicans beat democrats and take control of the u.s. senate. the nonpartisan center reports ads funded by the koch brothers have funded 44,000 tv ads. in many races democrats are now highlighting koch industries most controversial practice.

>> through giant piles of illegally stored pet coke, they've spent millions attacking terri lynn land. land is is for them, not you. and attacking tom cotton, linking him to the koch brothers and that he shift jobs from arkansas overseas. >> it pretty much killed this town. >> now they say being there, with big expensive tv ads attacking mark pryor. >> they moved jobs overseas. >> nobody should be able to buy

senate seats. >> nobody. >> the koch brothers believe loosening regulation will create profits and help the economy. and the supreme court rules that their campaign efforts are legal. the national education association is now hammering dan sullivan over his claims he supported teacher pension. >> when you teach middle school music, not everything is going to be in term. i sudan sullivan's tv ad about teacher retirement in alaska, i thought you got to be kidding. me the truth is sullivan sold us out. there is a lot of news this weekend in iowa. democratic groups are now atta attacking republican senate candidate joni ernst about a republican group meanwhile hitting bruce braley for missing veteran's affairs hearings.

>> as a member of the veterans affairs hearings, bruce braley skipped 75% of meetings. what was on his schedule? he some how had time to hold three fundraisers. >> . the biggest democratic party event in iowa of the year is this sunday. tom hearken picked with barack obama from a few years ago, will invite 6,000 people to an july steak friday. this wilin attendance is former president and mrs. clinton. this is mrs. clinton's first time here. mrs. clinton said she will announce her plans by january. today in toronto rob ford announced he's dropping his re-election bid for mayor. ford is suffering from a stomach tumor that doctors have called significant.

supporters of ford believe the condition must be especially serious given that ford stayed in the race early despite bees photographed on two separate occasions smoking crack. ford's brother is considering entering the race himself. finally in washington president obama got a fresh remind that are his job is not as cool as it may seem. the president and first lady went to school to help stuff backpacks as a public service. the students were told that someone important was coming. live to what a sixth grader said to the president. >> i really wanted it to be beyonce. >> i understand. >> malia and sasha would feel the same way. >> oh, man. >> no love, no love. even on a day of service can the president--appreciate it. have a good weekend. >> let's get you to other headlines making news across america right now. roxana is back for us. >> reporter: tony, in ohio police have recaptured three men

including a shoot who are escaped from prison overnight. the men climbed over a prison fest. law enforcement caught one of them immediately and the other two several hours later. this infrared video shows the police arresting t.j. lane. he's serving three life sentences for killing three teenagers and paralyzing others in a shooting spree in 2012. the school superintendent said that the prison break made the community anxious. >> the last several hours have certainly been very difficult as we come to grips with these developments. the individuals now back in custody. there has certainly been an undeniable, pro found and deep impact on our entire community. >> the prison warden are investigating exactly what happened. they wouldn't say if the men planned the escape together. they have been moved to a maximum security prison. the pentagon is searching for a pilot after two jets

you wake up the day after graduation. you do have debt. you don't have a job. it's not entirely new, but those facing that challenge in the current economic environment are finding it daunting and not very pleasant. we take a look at two different young people asking is college worth it question, and addressing it in two very different ways. >> it's going to excavate a little more this way. >> 18-year-old avery hutchinson tackling a nasty job. >> and 34-year-old jill looking for a job, but getting a lot of e-mails like this one. >> unfortunately, we will not be moving forward with your candidacy at this time. >> avery is an aparentiv apprentice plumber. jill wants to work in arts management. school was not cheap. >> you're in debt $70,000. >> yes, yes i'm. >> how does that feel right now?

>> terrifying. >> avery tried college for a year but it just didn't take. >> what are your college buddies doing right now. >> partying, having fun. j. >> he makes $14 an hour and he'll earn more as he gains skill and experience. >> i'm working on it. they're working on and a career, too, but they're not making money, and they have to pay off those debts. >> total student debt tops 1 trillion-dollar. >> 70% of college students with four-year degrees graduate with debt. the level of that debt is $29,000 on average. study after study shows their earning potential is much higher than for those without a degree. researching and teaching the economics of education.

>> here's another big number. $300,000. what does that mean? >> the $300,000 is a conservative estimate of the gains from getting a college degree compared to a high school diploma minus all the costs of going to college. however costly it is, ultimately there is reason to think that it pays off. >> jill certainly hopes so. she's glad she got the education, but those grad school loans come due in january. it's pointed out that advance degrees carry greater earning potential than undergrad degrees, but he did mention college and it's not a good fit for everybody. >> it's a good for most is how i term it. >> all the ditch digging he figures add up to a head start

in adult life. >> you'll always need plumbers, and that does not always go the same in other professions. >> at some point everybody needs a plumber. >> one thing you don't want to do is go to school and not finish, not get that degree. then you leave with loans to pay and without a job. if you're going to endure the pain make sure you stay there. >> what about the cost of careers? >> great point. you really have to start thinking about this early. it is the kids who are 17 and 18 like avery who are making these decisions long term. the college counselors at high school levels i talk to say they want to make kids aware as early

as possible in high school and tell them as often as they can about the mechanics of college loans. you borrow money. you have to pay it back. you may be paying it back. they also say it's trillionth to make them aware of all they are options. >> alan shuffle letteallen schauffler, good to see you. catch our new series right here on al jazeera america. we're back in just a moment with more news.

>> you know, outer space has been called the final front tear, but sometimes to go up you must go down. now four astronauts have turned into aquanauts. they're training under water off the coast of florida. we go to jacob ward our science correspondent. what is the purpose of the undersea similar plater and how close is that to being in space? >> reporter: they find it useful to send them down under the waves. one thing you can simulate what it is to be weightless. the feeling of being without

gravity is easy to replicate if you have the combination of a weight belt and you achieve neutral bouyantcy. and more importantly is the psychological experience of being underwater. these astronauts down there for seven days together. we spoke with randy, who is running the mission for nasa. we asked about the psychological implications of being cooped up in the space no bigger than a school bus. >> how do we all get along? imagine the mission to mars where you're in the spaceship for nine months in one little tin can together. if you have people who can get along, resolve differences, make dinner and still enjoy each other's company once they get to mars. >> other programs that have simulated what it's like to mean

together for nine months have resulted in fist fights, unwanted kissing, and it's the psychological thing testing out here. >> it can be scary. the idea of being 60 feet down, i would love to try it, but the idea of going to space makes me a little jittery. how are they literally dealing with the scare factor, the panic factor that is involved here on some level. >> that's one of the things that men and women who try out to be an astronaut or cosmonaut. they're screened specifically for the ability to not freak out. i could not do it. i would be scratching at the walls. you have to wait 12 hours before you get back to surface because of the repressuressization that they have to go through. we asked them had a is it like to be stuck down there? this is the upbeat things they

had to say. >> you're only a visitor for a few minutes because of the problem with decompression. but when you're living down in saturation you really get to enjoy it and watch it as it really is. that's a neat thing to help you prepare for going into space. space is completely foreign as well. equally if not more so in the ocean. >> reporter: that's really the thing. you have to think of these astronauts as super human generous and it's a testament of how brave they are to hang out for a week off the key largo. >> jake ward for us in san francisco. thank you. >> thanks. >> ththe america corp

celebrating 20 years. 900,000 people have joined the program. those volunteers have served more than 1 billion hours. america corp members have earned (270)000-0000 in scholarships. >> scientists have linked an extra chromosome in down syndrome with those who have alzheimer's disease. as people got older they would get old enough to get alzheimer's disease. we have a drug that would prevent a chain of events from starting and ending in dementia. >> the researchers believe that the drug is lukein.

it is given to people after bone marrow transplants and is currently used in their alzheimer's disease trial studies. move over t rex. when it comes to terrifying the king was underwater. underwater hunting massive sharks. >> reporter: coming up on real money using oil as a weapon against russia's vladimir putin. we'll show how it could hurt and how it could hurt some of your investments. we'll look at start ups that bring groceries right to your front door even though that failed at the dot-com bust. all that and more on "real money."
