will act like a cue ball - striking an argon nucleus in just the right way.he argon nucleus would recoil through the liquid argon and a little bit of interesting chemistry would happen. the energy temporarily will make some molecules which will decay and emit a flash of light. so the irony is although dark matter doesn't interact with light in any way, once it hits the argon nucleus, what well detect is a tiny flash of light. >> reporter: this device, a photo-multiplier, is designed to see and record those tiny flashes in an array of extremely sensitive lenses and sensors in order to give the detectors a fighting chance of success, workers here keep snolab squeaky clean to remove as much background radiation as they can. everything that comes into the lab is thoroughly wiped down. everything. and everyone as well; no exceptions for visiting reporters. i had to remove the clothes i wore in the dirty part of the mine, take a thorough shower, and then change into clean room clothing that stays in the lab. snolab has some deep roots in the hunt for the tiniest pa

the compounds pearson looks for are indicators of the existence of eukaryotes, or organisms with a nucleus, the ancient relatives of today's animals and plants. to gain access to these compounds, pearson extracts fats, or lipids, from the rock sample. once the lipids are extracted, they are run through a mass spectrometer, which indicates what kinds of compounds are in the sample. pearson: so, when we look at a mixed sample and identify what kinds of compounds we have in the sample, sometimes we see a compound with a mass spectrum like this, and this is the mass spectrum of a sterol. the sterol is related to the compound cholesterol, which is something we're familiar with. and any time we see a sterol, we interpret that as meaning there was a eukaryote in the sample. and this is significant because we're able to then look for molecular fossils or biomarkers that record eukaryotes before eukaryotes became big enough to leave large, macroscopic fossils that we can then see. narrator: but sterols do more than tell us what kind of life was present. they provide evidence for its environment. th

your only tool people to continue i think in mind that the nucleus. where to go to walmart. i know it soaked into the semester to be sold for more than one hundred and sixty thousand us dollars to much for normal people but people do really like the dog was not considered expensive want to know if it's possible. i'll add a star for kant the fountain to get there. some people might think that dr would try to like them a while back. it looked like he'd gotten a bit it might be a reasonable price it could cost tens of thousands of us dollars. to safeguard a suburban. i don't think it's a big dogs should be kept the crowd would have been happening. nowadays many people elected as the market then. i can't guarantee that i know what market. in a courthouse. i think that when people like it. the death of a copier to bed a method to be still pretty much a hundred fifty five thousand dollars. the purebred one completed standard the pontiff called in the dark. pursued by people who pay big money for doc articulate for tibetan mastiff. have a huge margin you can trim down the number of

i believe that i love that the denison to meet the high is cutting loose the round ball and the nucleus which it is very important when we should try to pull forward and said film and you freakin hot. he was on board. in discussing the current crisis of the region. we did our goals and we would be much more efficient. how can we sold the iraqi crisis. we sell you a token we sold this year and crises without you but that's why i'm really believe that the title with this country is important. and we should definitely ticking clock of the fact that we adults having the run aboard these no solution to be the least so the weakening of them started and failed to bring you a special preview of the long lake geneva to tok send the gall to special covers london is one of the event from wednesday still ahead on tape. russian officials on the fences and went on a vogue right now a delegation from moscow given access to the mosque much into this and they kept this to everyone in washington of its unfulfilled promise to show that will facilitate the sad loss to explain the record breaking cost of th

for example in the sun is is the nucleus problem and by this time that unfold in avoiding what has been happening inside the five foot seven against india to be buried he was an ipod. in the dish did their footprint of the phone up so well i need an idealistic situation in the domestic situation and the press. this is a revenue problem for that but the invisible do is say the security and stability of the country and that he did for example in a bottle as well so you're a stupid acted as a bid to address concerns being expressed. the group as the static as in this day was and is as a wonderful piece from a sore nose into india continued as it seems even in fact some of the guys eating guests of the big names would be what had been caught in this day. so complex and we have what some corporation from the nepalese government but i would be needed for the countries in twenty oh one this time consuming to sop up the other side of august and end up on that dish. these countries would appropriate day will be diligent in doing so. there would be probably tried operations if required that does

and we are deficient in manatee and what kind of image you do need to be fifteen minutes and to the nucleus of a deal couldn't resist a manatee. so we have all optimistic plans for the ambitious plans call for cutting of thing people could because to me go what to call it and then to nuke of and the next ten years of school. what we know how hollywood has the story made an imprint all around the world to die in india how has the korean wave been received. i know my friend has been to india in on them and then you've seen it put us in northeastern india has taken to to lie and keep off the new mini degree of licensing boys to include this in lakewood and stars and so on. and the vivid it does to people without caveat in north eastern india on the society on the lives of the country. according to other people is his cough is stuck between appeasing the pope and in india foreign investors take so much for your time tonight they should really do. for your dns and another began get the latest online from seoul expert analysis from ages fourteen with the viewpoint all the koreans local network an

dust left over from the nucleus could fall as meetos, dust. the antarctic is a great place to find them because of the white expanse of ice. against a white background they should be easy to find. they should exist in a pristine state. keeping our fingers crossed scientists there might be able to find these. n.a.s.a. has got good funding, a billion increase, a four-year life extension through 2024. how important is this? >> n.a.s.a.'s been doing a tremendous amount on essentially a seriously reduced budget. in order for n.a.s.a. to tackle the big jobs of going to the moon or mars, they need to up the budget significantly. this billion dollars extra will help them to continue the work on the launch system that we need to develop to carry the orion-manned capsule. n.a.s.a. wants to do testing and have it ready to go. the funding will help to keep the operations rolling on. >> and a quick last question in. there's shocking news out of iran. according to the iranian government newsagency. the u.s. government has been run since 1945 by space ailien

today, there is no central al qaeda nucleus. references to a core al-qaeda imply that its defeat would dismantle terrorist efforts around the world and eliminate the terrorist threat to the homeland. this is not the case. over time, the term al-qaeda has come to symbolize an ideology of hate toward the west with a goal of establishment of a caliphate, rule by sharia law and the pathway there through violent jihad. we're seeing it's spread play out in the middle east, in africa, and in the caucuses. although many terrorist groups subscribe to this ideology, we must understand that they are independent organizations, planning and conducting operations without the oversight of an al-qaeda central command. the only core is the ideology itself, and defeat of an ideology requires more than just drone strikes. the failure to recognize this truth prevents us from understanding the real threat from islamic extremism and clouds our judgment in fighting against it. ultimately, you cannot defeat an enemy you are unwilling to define. the sec
