Video, there is a lot of white material coming out of the end of the pipe. and that is the gas. in fact, you can see it float upwards in the video. quite a bit more rapidly than the oil does. >> jeff: and then it turns dark. >> right. and thats the oil. toward the end of the video. i based my analysis -- yeah, go ahead. >> well, i mean, as another engineer, you trace a particle, then, and you have software that measures how fast its going? >> exactly. the name of the technique is called particle...

In the sky. thats when it started to affect plane travel, right? but now its settling back down where we live. and now it is going to become more of a health problem, and maybe all those 3m-m 95 masks we bought for the swine flu -- h1n1, now well get to those use, finally, that i have sitting on my shelf. >> so a lot of it coming down to earth, starting to touch north america right behind you, but it is a concern. its a real thing. its not just air that dissipates, its real particles. >> correct...

For a minute you and say, really? is that safe? >> well, theyre not going to go up in a 747, theyre probably not even going to go up in a jet. a prop plane can survive a trip around an ash cloud a lot better than a jet can. with jets, this is the thing to stress, is that, you know, pulling that particle, those particles, through a jet engine, thats the really dangerous thing, so its just a commonsense precaution that you wouldnt put a planeful of passengers in harms way, but a group of trained s...

Of lava spewing out there, but this is the big issue right now. a cloud of ash thats taken up the airspace from 20,000 to 35,000 feet right where jetliners usually fly and this is drifting east and south and thats playing havoc with europe, grounding planes and closing the airports all over the place. why is that? well, first, its because this can look like normal dust up in the air or normal clouds so its impossible to fly into by mistake, but this is nothing like normal dust. this is so fine t...

Later today. we will see. this is the problem. we showed it to you yesterday. >> highly magnified particle of volcanic ash. >> this is your brain on drugs. this is what a particle of ash looks like in the air. it melts. even if you fly through a little bit, that ice and that glass thats on the back of the plane and in the jet is going to stay there a very long time so you cant fly through any of it, ever. >> thats what were worried about because as it dissipates, when you see it right from the v...

Of the airports in the uk are closed. >> correct. this is not precautionprecautio. this is a mandatory do-not-fly zone literally, because this is a particle blonwn up many thousands of times. you dont want that going through your cars engine, let alone a jet engine, and this because its ash melts back down into lava and then like glass, like you said earlier, like ob siddian, and then it deposits itself on the back of the jet and the jet engine on the plane can choke itself. >> yep. >> look what...

May just take us back to the very birth of our universe, but this breakthrough is not just about the past, but our future. it could unlock all kinds of scientific mysteries around us. cnns atika shubert shows us why researchers around the world are buzzing. >> reporter: it took 16 years and more than $10 billion, but finally, the large hadron collider, the biggest scientific experiment in history has yielded results. scientists watched in suspense as two particle beams traveling at close to the ...

We have to do a lot of work, we have to understand physics in this new region of energy. >> reporter: one of the top goals, to identify the much-theorized but never before detected bosen particle. the so-called god particle that gives mass to particles, meaning it allows solid structures like, say, a table or a chair to exist. there could also be new discoveries in what scientists call super symmetry. the idea that every particle in our universe has a super partner mirrored in another quantum di...

The earth is still after 5 billion years. no, this cannot in any sense destroy the world. it might shake up some scientists views about how the universe works if we dont find the particle you referred to early as the god particle. but theres no chance of anything going wrong in terms of a black hole. >> doctor hastings, thanks so much for coming on and trying to explain it to some of us nonphysicists. we appreciate you coming on today. good to see you. >> thank you, david. >> that does it for me...

These clinics have been in seattle school district for 25 years. they have been controversial in the past. they are also very expensive, costing taxpayers this year alone almost $3 million. they are actually run by the county health department, as you mentioned. they say in this case no laws were broken. >> at any age, in the state of washington, an individual can consent to a termination of a pregnancy. >> and washington state is one of just 15 states in the nation without a parental consent or...
