as much nitrogen as the samplers nearest to me, further away from the road. this is about, oh, 150 yards from the road. narrator: before the study at the woods hole research center there was little understanding of the amount of nitrogen pollution coming from traffic. stone: because there's a limited amount of land area on cape cod, the number of new roads is not very large, so the roads are used more intensively and roads that were designed for maybe 10,000 cars per day now have 20,000 and 25,000 cars per day. there's really no place to build additional roads. dr. davidson: business as usual is not really an option. our economy is based upon having tourists wanting to come here and spend time here. they're not gonna come here if the estuaries are full of algae that smell rotten. so it's extremely important, and we're getting to a tipping point where we have to do something. and i think the same is true across the globe. dudley: we know that people are still gonna want to come to the cape and that growth is gonna continue so what we're really interested in tr

. >> we have found the osmo sampler.. >> we have recovered the infamous milk crate. we looked around this area about to finish our second mission of the day. >> the oxygen temperature sensor and using it to stick in one of these vents to determine how much hydrothermal water is coming out. >> an abundance of octopus offer a stunning visual but it's obvious something is occurring. >> what are you seeing? >> looks like it's dead. when we deployed this there was a lot of water coming out now there's none, no signs of flow coming out whatsoever. >> it's still weird. >> definitely still weird. i don't know how to explain it. >> this is how science works. what's confusing now could lead to a break through tomorrow. despite this eight-legged problem. >> so you keep trying set this temperature probe but it keeps falling over and of all things octopus keep getting in the way. >> as experiments lead to more questions we begin our two-mile assent back aconsent ascent to the surface. >> atlantis, we read you loud and clear. swimmers

. >> wong processed the sleeves and cuffs with a stub sampler, an aluminum disk with a carbon tape adhesivece. the sample was bombarded with electrons, and the x-rays revealed three chemical elements -- lead, antimony and barium. >> if those three elements are present, then that leads me to believe that that particle is actually a primal gunshot residue particle. >> this meant kevin rice's killer was wearing this sweatshirt. was it possible that the killer lived in the auburn manor apartments? >> the decision was made by the supervisors to send those keys out with teams of detectiveso see, or at least rule out, if those keys went to any of the apartment buildings. >> rockford police. >> investigators tried the keys in dozens of apartment doors, a tedious, time-consuming process, with no success. >> the apartment complex, i think it's four or five buildings or six buildings, you know, there's a lot of apartments. that's why they set out with four sets of keys and teams of detectives. >> they were beginning to wonder whether this was a dead end until they got to the bottom floor and finally g

. >> had cheesecake sampler. >> nice fireplace. >> there was a fireplace. after our tesla test drive. awaiting the petrobas release. let's go to michelle caruso-cabrera in rio de janeiro. what should we be looking for? >> we were given guidance the numbers would come out very soon after thundershowers. it hasn't happened yet. officially they are late. let's give them the benefit of the doubt. could be they are still writing up the press release or do an english translation as well. the board had to vote on whether or not to release these. the expectations were high that the vote would go for yes. there's a possibility that maybe we won get them. that's devastating to the stock. in the meantime i assume we'll get them sometime in the near future. we're looking for a level of credible estimate of the impact of fraud on the balance sheet. we'll be looking for a level of writedowns and impairments on assets driven by this ten year bribery scandal and scheme that has come to light in the last year. the difference between a write down and impairment you have a tr

the primary care and samplers that were identified, i didn't know they were exemplars. i think data is the biggest frustration and that is where i would go. mr. clinton: i want to tell you why i asked you his question. i spent most of my life trying to change things, i was always making so many mad. 40 years in public life, but i found that the resistance to change that was self evidently good like in just the examples you cited, was often rooted in naked self interest. that is what you talked about. but also, the comfort of the way things are. people -- a lot of people do not want to think about doing things in a different way and it is -- and society is an enormous. it is staggering, the idea of change people's boxes with which we have arranged peoples reality, that is the problem. and the other problem i found this, if you want to make a change that will make things better, but has more moving parts than the way things are that is hard. i will give you the best example, with energy. if you want to build a cool -- coal-fired plant and you want to accelerate climate ch

what arnie and his team did was identified in samplers in primary care. the top quintile, the top 20%. all in per capita costs, the lower 25%. he found a little less than 5% of the practices surveyed did both. -- high-quality, low-cost. they went out and visited 11 of those practices and came up with 10 features, 10 features that we believe correlate to that exemplary performance. now, we are in the process of what we call "limited market tests," with five practices to determine if in fact these features are the cost of that performance -- cause of that performance. replicate the features in those practices, have a control group to determine if in fact, it is conversation. and then, really understand what of those features have leverage in terms of improvement. then, go to 30-50 practices and replicate and then go to a mass replication. now, we do not proclaim to know how to mass replicate, if that is even a phrase. but that is what we are determined to learn. we think that there is a lot of different approaches in adult education that we can use whether
