traditional dna analyzing the nucleus of the cell.ucleus are mitochondria that can be identified although not as precisely as traditional dna testing. >> most hairs from crime scenes have very, very little amounts of dna. however, there is more mitochondrial dna, however there is more dna therefore in hairs obtained from crime scenes most of the time we can't obtain the dna convention where we would fail with neek leer analysis. >> to identify the dna sequence, a pcr test was conducted and the dna sequences from the blonde hair matched patricia's dna profile. this was enough to convince prosecutors that patricia was at the crime scene and inside joann katrinak's car. she was arrested and charged with two counts of first-degree murder. prosecutors believe that she was in pennsylvania and not north carolina when she called for andrew katrinak. >> hello? may i ask who is calling? >> when joann answered the phone, patricia's hopes of meeting andrew for old times sake were quickly dashed. >> we have a baby now. we're happy together. just l

that he said would be the nucleus that would host the city. and san francisco gave further incentive to expand the city's network. a project by way of tunnel leading into chinatown by way of north beach. in december the first streetcar was driven into the tunnel. just two years after its berth, muni had added two lines. and k, l and m lines that span out from westportal. in 1928 the j line opened heading west to the beach. in 1944 san francisco voters finally approved muni take-over of the market street railway. by then motor bus and trolley bus improvement had given them the ability to conquer san francisco's hills. after the war most of the street-car lines would be replaced with motor or trolley bus service. in 1947, the mayor recommended replacing two lines with motor coaches. and it appeared that san francisco's iconic cable cars had seen their final days. entered mrs. cluskin, the leader to save the cable cars. arguing that the cable cars were a symbol of the city and she entered a charter placed on the november ballot. it passed overwhe

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. this

it's the nucleus of its spirit. its spirit is about love and sharing.: this is the sanest acre on the planet. russell: and it's bringing dialogue about important subject matter to the forefront. stuff that has been swept under the rug and has been hidden. nicole: the 99% versus the 1%, inequality in america was never something that people talked about. it was the most on target kind of demonstration protest i've ever witnessed. [protestors chanting indistinctly] jeffrey: what occupy wall street is saying when they say "we are the 99%" and when they are pointing to the 1%, it's not envy. it's not saying, well, they're rich, that's bad. it's saying that people of wealth in this country have not taken on the responsibilities that they need to, especially the powerful corporate interests, especially wall street. jake: i would say corporations are in control of our democratic process. lillian: i've been visiting here, uh, several times a week because i want to show the young people that there are older people who agree with them and who are really depending

in fact, they are the dominant player and what they are building is the nucleus of hudson yards but allre other developers and other major owners -- brookfield is a perfect example, they own substantial pieces. erik: how important a commercial market is brooklyn? stephanie: we complemented my neighborhood and now he wants to pump up his own. erik: i ask an open-ended question. >> i've had an agent in brooklyn for a long time and bruce ratner pioneered that area. his buildings are largely full now. then a family developed dumbo and those buildings are full. now we have a new generation coming in with dumbo heights. our firm put etsy in its space and they took over 200,000 square feet. it is going to span out from there. we're going to see greenpoint and all kinds of areas we never thought about, but it will take time. it's also going to be a case where right now, the rents are high in brooklyn. if you want to go to dumbo heights, you are talking about rents north of $50 -- $50 a foot. value is a very different thing in manhattan right now. stephanie: thank you for joining us. she's that

. >> nucleus special agents on the ground at night in the white house driving through a barricade drunk it seems to me that the only discipline that you could exert would be caused by the ability of you and your staff to terminate as punishment so that every other agent knows well i don't want to go there. that director is going to fire me. that's what makes the mind work. what do you think about that? >> i agree with you. deep down within our agency as another's people want to see discipline. people want to be discipline. they want people to be held accountable. i just want to respect due process as frustrating as that is and then let my actions speak for how we are going to move forward as an agency. >> we will be watching. and waiting. >> yes mr. chairman. >> the entire house appropriations committee hearing with secret service head joseph clancy will air in 30 minutes on c-span at 8:00 p.m. eastern time and you can watch the hearing any time on our web site c-span.org. live picture of the u.s. capitol. the senate has finished its work for the day failing to advance the human traffic

there is a nucleus armed race. there are indications that saudis in particular are so alarmed that bad deal en is in the cards that they are already moving in that direction. what is your response? mr. blinken: if there is no deal, iran could rush to nuclear capacity tomorrow, which is what i imagine would spark an arms riace. to prevent that, would be preventing iran from getting a weapon. the model for this agreement is hardly one that other countries would want to foll ow. the iranian model is more than a decade of isolation and sanctions. if an agreement emerges, i doubt anyone would want to follow. the answer is exactly what we have been doing, or venting iran from getting weapons, so other countries don't want to do it, and build up their capacity for themselves. representative chabot: our concern is we are going to end up with a bad deal and they are going to get nuclear weapons if the other countries will feel threatened then the others will end up in the middle of that. other than iran is a far more danger

that formed the nucleus of isis in the city of derna. you've had isis spread to all three of libya's major provinces. and of course they have conducted some very high profile attacks against corinthia hotel and most recently tragic killing of egyptian cops. again, let me move to some thoughts about policy option. one thing that makes this so confounding, we're faced with a terrorist problem in libya that is embedded in a very complex civil war. there's no government to work through. there are two competing factions and we face this in iraq and syria and yemen is what partner do we assist on the ground? how do we work with forces on the ground? there is the danger that if we provide assistance to one faction, that assistance will be used politically against opponents in the civil war. where are we at right now with resolving this conflict? you had the united nations came out i think today and said if these peace talks next week don't resolve themselves, lead to some resolution, there is a real possibility of a u.n. intervention. we may be
