second world war, when the u.n. was created years ago. >> there's no peace in part. there has been little unity on the global stage. there have been rare moments of agreement in the u.n. security council on chemical weapons, and the growing threat from i.s.i.l., but nothing on a political solution to the dismiss of the u.n.'s humanitarian agencies. one of the agencies the world food program led. you must get frustrated when you look at the security council, and the lack of agreement on syria. i get frustrated - not only when i look at the security council, when i go into syria, and you see that there is no solution in sight. and i talk to the government and the e opposition and they are firm in their position and then i look at the people. i say "don't they see what i see?" can't they see the impact that their failure to compromise is creating in this situation.

bomb investigation. the car drove through the scene before hitting a barrier. two secret service agents were inside. it's alleged they were drunk. another american has tested positive for ebola in africa. the unidentified person and aid worker will arriving in maryland for treatment. john terrett is here with more. and we have new numbers showing how devastating the outbreak has been. >> we did, amazingly it's a year since the first case was diagnosed in west africa. in that time it's the worst outbreak history, with more than 10,000 dead. when some countries are ebola free, in other cases cases mount. >> tomorrow another american who conducted ebola will arriving in maryland. aboard a plane or under strict isolation protocols. that unidentified person will head to the institutes of heath

to be treated for the disease. the nia is one of a few medical centers outfitting an isolation unit. the patient got the virus while volunteering at a treatment center. this will be the 10th person with ebola to be treated in the u.s. today brings a milestone in the battle against ebola. the world health organisation announcing that 10,000 people have been killed by the disease. while a massive international response slowed the rate of ebola from proceeding. w.h.o. says it is far from over. >> in terms of the risks, the single biggest one probably at this point is the risk that the world stops looking at the disease, stops looking at the country. sierra leone and guinea remain entrenched in the fight with dozens of cases being reported. the world needs to keep paying

attention and give more. the w.h.o. says 400 million is needed to continue the mission, fighting the disease. in liberia, 12,000 people have been infected the tide is turning. the last ebola case walked out of a hospital days ago. the country will be declared ebola free after no cases emerge after 42 days. >> it goes without saying that the american patient arriving here tomorrow will receive the finest care that the world has to offer. sadly the same cannot be said for the people suffering over in west africa. >> it's devastating those three countries in so many different ways. john terrett, good to have you with us. thanks a possible break through in alzhiemer's. using sonic waves. researchers use an ultra sound to zap mice. they write that the treatment seems to untangle plant connected with alzhiemer's.

testing shows mice that received the treatment performed better. officials in california say there's no merit to a lawsuit over cell phone tracking. the police department quietly used a controversial technology to keep tabs on the mobile devices. science and technology correspondent explains it worked. >> half of americans own a smartphone. the ability to detect a smartphone and follow it from place to place would be an incredible convenience. it turns out for at least a decade place have been using a secretive technology to do that performed from a contractor using ramp money is called an mc catcher, known by the brand name sting ray. the cell phone registered with the towers. a sting ray pretends to be that tower, and fools every phone within range to handing over

identifying information. it can pinpoint a suspect's location to a street address. it's possible to use the technology to scoop up every phone on a street corner or anyone at a protest. imagine that you were present at that protest, or maybe you lived up stairs. if the police were here using a sting ray, your fan -- phone could put you on a watch list. we were shown emails from the oakland police discussing protesters in the context of sting ray technology. it's not clear where and how it's been deployed. >> we have strong suspicions when people report their cellphones acting weirdly, the interference with the ability to communicate, the fbi - it was 2-3 days ago, it admitted that people within range will have a disturbance in the use of their cellphones. when a sting ray is activated.

>> we ask current and former prosecutors to explain the value of sting ray technology no one would explain or endorse it. a public records request reveals that in florida alone, 3 dozen police and sheriff's departments spent millions on technology and used it on hundreds of cases. the technology was a secret until recently. >> the manufacturing of the sting ray, the harris corporation, a company based in florida. has a non-discourage agreement. it requires law enforcement agencies to sign where the agencies agree not to discuss the purchase and use of these technologies. >> in fact, the federal bureau of investigation is behind the nondisclosure agreement. and it compels a purchase ear of the sting ray to find it. neither the harris corporation or partners or customers responded to requests for comment.

in emails a clear pattern of secrecies emerges. in response to a lawsuit filed by the a.c.l.u. an federal bureau of investigation officer publicis the position: . >> when, you know we allow police to operate invasive technologies in secret outside the judicial system outside the normal channels of oversight and procedure, we intrude upon the civil liberties. several court cases are under way across the country, most to compel law enforcement agencies to use sting rays. it may be the best way to pursue suspects. so far, there are no legal checks on the technology. >> a spectacular night-time

launch for n.a.s.a. kicking off a fascinating mission. next what scientists are looking for in space and how it answers questions on earth.

. >> three, two, one, zero. and lift off tonight - n.a.s.a. is boldly delving into a mystery in space. the rocket lifting off. it's carrying the magneto officeric multi-scale mission. four probes set to cover the interaction between the earth and the magnetic fields. we are joined from philadelphia tonight from derrick pitts. explain this to us nonscientists. >> here is how it goes. astronomers want to characterise how the magnetic field around the earth and stars like our son generate energy. they do it through a process

where their lines cross. they disconnect and when they reconnect they release enormous amounts of energy. we see that release of energy in terms of solar flares big eruptions off the surface of the sun. here on the earth we see a smaller scale event which we characterise as the aurora or the northern lights. we want to understand how the process generates that energy. >> other are than understanding it what are the practical implications, how does this help us on earth. >> the way it helps us is we understand the environment that we live in. it's best to understand how the system does this is it blasts systems out all the time especially when we have intense flares. what we want to understand is

how intense they'll be how they affect the earth's magnetic field, and how does the magnetic fieldwork, so we know how well protected we are from the biggest eruptions. >> whether they can disrupt us on earth? particularly in terms of satellite. it's best to understand how it protects us and how weigh may be act apply information we have. >> this mission will cost about a billion with missions. the question is whether it is worth the huge investment. you think it is? >> i think it's worth it. it's the pursuit of the knowledge. it helps to understand our environment. it's like asking the question of if we think a large amount of money is worth spending so we can better understand our oceans

or better understand our atmosphere. understanding the environment is critical to our success here on the planet as a life form and i argue that understanding the magnetic field is critically important. >> i only have about 30 seconds left. we have the four probes orbiting the earth and each other, with so much space junk off there. is there the danger of a decision and a probe. falling out of orbit and causing problems. >> there's a risk that some kind of collision can happen when you have an important asset. everyone makes sure the orbital path is clear of everything else as much as possible. you don't want to lose the access. thanks for explaining this to us. spectacular night-time launch. thanks i'm antonio mora thank you for joining us for the latest news any time head to domenic commisso.
