. >> and i'm livia. here's our top story for this week. >> we'll start with a report that combines amazing science, courage, friendship, and music. it's the story of a teen who's triumphing over a very difficult disorder. >> dystonia is a neurological movement disorder which causes uncontrollable pain and spasms. >> most of us have never heard of dystonia, but jake can describe it with painful, personal details. he's in high school now, and he's been living with the disease since fifth grade. >> slowly, it's got worse and worse to the point where i couldn't send him to school because it was too painful to write and to walk around the school. >> i was in a wheelchair. i had no quality of life. i was just sitting on the couch doing anything to try to cover up the pain. >> then, what can truly be described as a medical miracle -- recent research led to a breakthrough treatment called "dbs." >> dbs is deep brain stimulation. it's when they put a battery in your chest, a wire in your uppes into your brain. it

. >> and i'm livia. here's our top story for this week. >> scientists call them "neos" -- near-earth objects. they're asteroids and comets that might someday be on a course to collide with our planet. it might sound like a movie plot, but tyler tells us that nasa takes neos very seriously. in fact, all should. >> so, do you worry that something from outer space may crash into the earth? >> i think the chances are pretty slim. >> sometimes, like when i'm daydreaming in the middle of history class. >> no. i don't worry about something from outer space crashing into the earth. >> i don't worry about it a lot because i feel like we would have had a lot of warning from a lot of people and on the news, so i don't think that it's much to worry about. >> the universe isn't quite as empty as it seems. icy comets and rocky asteroids have been hurtling through space since time began. they're formed and propelled by explosions, collisions, and gravity. and they can be gigantic. this asteroid is 36 miles across. that

. >> and i'm livia. here's our top story for this week. >> teens are often under a lot of pressure to do well in school, but that doesn't mean it's okay to copy someone else's hard work and pass it off as your own. teachers call it "plagiarizing," but, as we see in this report, you can also call it cheating. and don't think you won't get caught. >> you've probably heard the word "plagiarize," but what, exactly, does it mean? >> when you take somebody else's words or ideas and you use them as your own. >> that's exactly right. in fact, the word "plagiarize" comes from the latin word for "kidnap," only instead of stealing a person, modern plagiarizing means stealing someone else's work. now, most of us won't copy another person's work exactly. we know that's cheating. but what if we rearrange things a little? >> everything is changed around just slightly just so you can call it your own piece of work. everybody does it. it doesn't mean it's right or wrong, but it happens. >> it depends how much you change

there wasn't no it's a religion inside it was sane and there was or no it's religion and got to the livia and yet we see these laws over and over again even yesterday in the jordan times i posted the bit against the war minister posed in such lawyers let's pick up a will to the iraqi f.m. said that weapons are still flooding into syria and we've been reporting on this for a while the coming from turkey and the us control how can these countries supplying arms be sure they are not getting into al qaeda is hands is a question we've asked before all the good to ask it again i guess as the as the violence continues i don't think they care i think they would be happy to see a civil war in a breakup of syria the kurds for example would love nothing better than a breakup of syria of course they would also like a portion of turkey iran and iraq so on the turks are doing some amazing things by promoting though this behavior gets syria could come back and bite them on a portion of their country was carved out by the kurds after the meeting in cairo the a certain position group still conned into pay

syria gets solved, egypt data will -- stabilized in tunisia looks like it's moving along quite well, livia gets stabilized. is really critical or any number of things could be a major eruption. >> let me go back to the intelligence issue that i started with and that is the question of whether as these issues become more complex and we find ourselves facing threats in northern mali and the northern part of nigeria and places that we have not concentrated on, do we have, particularly the human intelligence, the cultural knowledge, the geographic knowledge, to cope with these threats as they become more widely distributed, despite the set says -- success as you said? >> i think it is building. this is the problem. all of this requires cultural and language skills on the part of our people, and which the intelligence community has been making a major effort to improve. by john, it takes time. it isn't overnight. and you can't pick up 2000 years of history overnight and this is an ancient part of the world. so it is much more difficult. it is also interesting how divided this area is. countries
