from tisch studios in new york, hari sreenivasan. >> good evening. thanks for joining us. the winter olympics in russia are only three weeks away and there's been another violent clash between russian security forces and militants. authorities said they killed seven of the militants in a shoot-out today. they said those killed were responsible for a grenade and car bomb attack outside a restaurant yesterday that injured at least 16 people including several policemen. the incident occurred in the mostly muslim region of dagestan. and late last month, more than 30 people were killed in boll get grad. and the death count continues to rise in the aftermath of that attack in kabul, afghanistan, yesterday. police there now believe 21 people including two americans and two canadians were killed after a bomber blew himself up outside the entrance to the restaurant frequented by foreigners. then two gunmen burst inside. three worked for the united nations. and the taliban claimed responsibility. it said the attack was retaliation for a u.s. air strike that reportedly killed eight c

hari sreenivasan takes the story from there. >> sreenivasan: joining me to discuss the report is katherine baicker. she is professor of health economics in the department of health policy and management at the harvard school of public health and was one of the authors of the report. wuferning headlines, let's dig deep nears this, 40%, that seems like a very large spike in er usage. what does that actually translate to for the people in the study, how much more did they use it. >> well, on average people in the control group went to the emergency department about once during the 18 months that we looked at. and people without got medicaid went 1.4 times. so that's about a 40% increase. it's helpful to think about why people were covered by medicaid versus not in our study. oregon had a lottery for a limited number of spots ined medicaid program and they drew names from a waiting list by chance so we were able to compare people who didn't gain access to the program through the lottery to people without did. and that gave us a really good control group to figure out what happened when people

. >> ifill: hari sreenivasan is in new york and spoke with margaret a short time ago. >> so, margaret we've been waiting for this meeting for quite some time, what are the expectations. >> by the standards of international conferences like this, this -- expectations are pretty low there is really no shared sense of what the goal is when you talk to the two adversaries here, the syrian government and the opposition. tomorrow's set of speeches is hard bargaining in geneva friday, the hope by the united states and the u.n. and most of the countries there is that at least you'll get a united chorus from the 30 or so different countries that are speaking tomorrow that the answer is not a military solution but a political solution. and they hope that the two adversaries will hear that and that when they speak there will at least be some sense that they, too, want to pursue that even though they have very different end states, their visions are very, very different. secretary kerry's theory has been for some time now that if you put at least get these two warring parties to sit down for the

hari sreenivasan has more. qr cor william brajham is in iran this week on a reporting trip. we caught up with him earlier today. william, welcome. so this week iran and world powers worked out the technical details of the internal deal over its nuclear program. what has been the reaction on the streets of tehran? >> well, hari, the deal has been received relatively well so far this week. in fact, members of iran's revolutionary guard who for weeks have been criticizing the negotiations and the deal offered what is considered mild praise this week. so that was considered a bit-of-a step forward. that said, president obama set off a bit of a diplomatic does they will week when he and his statement on sunday describing the deal referred to it as quote dismantling some part of iran a's nuclear infrastructure. which is a charge the iranians completely reject. the foreign ministry rejected that statement and earlier this week president rouhani felt compelled to give a speech where he said that the deal, in fact, represented a quote, surrender of the western powers to iran's will.

hari sreenivasan is our guide, beginning with some background. >> sreenivasan: net neutrality is the idea that broadband internet service providers: comcast, time warner cable, verizon and others should treat everything that flows across the internet equally. that means preventing service providers from creating fast lanes for sites they have business ties with, such as streaming video services like hulu or netflix. and slowing access to others, like amazon. it also means not charging more for youtube and other sites, based on their heavier bandwidth use, or in exchange for faster speeds. all of which, could affect what consumers see online how fast, and at what price. the principles were set out by the federal communications commission nearly a decade ago. the agency enshrined them in its open internet order, adopted in 2010. but verizon sued to challenge the agency's authority, and yesterday the u.s. district court of appeals for the district of columbia found that the f.c.c. acted improperly. the 81-page ruling said the agency is wrong to classify internet service providers as inf

and as hari sreenivasan reports, some are wondering whether the two sides will even keep their plans to meet tomorrow. >> sreenivasan: u.n. envoy lakhdar brahimi met separately today with the syrian government's delegation and the opposition in the wake of yesterday's tense, formal opening session. he declined to comment on his conversations or about prospects for face-to-face talks that the two sides are supposed to hold tomorrow. ahmad al-jarba, head of the western-backed syrian national coalition, reiterated again today that syrian president bashar-al assad must go. that idea indeed, many of the civilian opposition groups refused to come and none of the fighting forces-- secular or islamist-- sent representatives. instead, they've been fighting among themselves and against the more extreme al qaeda linked jihadi groups. today, al-qaeda leader ayman al- zawahri released an audio message urging the islamists to unite. meanwhile, the president of iran called for elections to decide syria's future. hassan rouhani addressed the world economic forum in davos, switzerland after his count

hari sreenivasan, in our new york studio, explores the potential impact of the guidelines. >> sreenivasan: we get two views. sherrilyn ifill is president of the naacp legal defense fund. and chester finn is president of the fordham institute, which focuses on the reform of elementary and secondary education. >> woodruff: the how big of a problem is this? what is the administration reacting to with these guidelines? >> well, the administration today really took the important step of recognizing what is a wide spread problem. what we saw in the clip is just the tip of the iceberg. not only in texas but in states throughout this country. we litigated a case in brian texas where students can get a class c misdemeanor ticket for using profanity in high school. and this essentially then leeches students with a record and puts students on that school to prison pipeline that we talk about. this whole idea of discipline, of changing what used to be in fractions that got you sent to the vice principals office and criminalizing them has essentially introduced the criminal justice system into our sch

hari sreenivasan narrates our report, produced in partnership with the pulitzer center on crisis reporting >> reporter: near a remote village in the eastern philippines, at a small camp in the forest. a man bites down on a plastic tube, adjusts his mask and disappears into water as opaque as chocolate milk. descending as deep as 40 feet, he breathes from a small diesel- powered air compressor, while blindly digging into the sides of a narrow tunnel. for hours at a time he fills bags with mud and rock that a partner hauls to the surface, where the sediment is broken down and, using mercury, panned for gold. according to thomson reuters, in 2012 the philippines was the 18th largest producer of gold worldwide. large companies are responsible for much of that, but there are also many unofficial, small- scale mines like these. many lie in the poor coastal province of camarines norte, about 200 miles southeast of manila. where some of the country's highest concentrations of the precious mineral can be found. but much of it is trapped in ore underwater. so-called "compressor mining" originated in

as hari sreenivasan reports, he may have reached a breakthrough >> sreenivasan: demonstrators from both sides of the syrian conflict highlighted the diplomatic divisions, as the assad regime and the opposition failed to meet face-to-face today. then, came this: >> tomorrow we expect, we have agreed that we'll meet in same room. >> sreenivasan: u.n. envoy lakhdar brahimi made the announcement after hours of meeting separately with the delegations. >> the discussions i had with the two parties were encouraging. and we are looking forward to our meetings tomorrow morning and tomorrow afternoon, as you know the whole process is based on the geneva communiqueÉ of the 30th of june, 2012 and i think the two sides understand that very well and accept it. >> sreenivasan: that communiquÉe calls for a transitional government, and brahimi acknowledged "there are different interpretations" of its provisions. earlier, the western-backed "syrian national coalition" insisted president bashar al- assad accept those terms before any direct talks. secretary-general badr jamous: >> ( translated ): the nego

hari sreenivasan has the story from our new york studio. >> sreenivasan: fans who've descended on new york for sunday's super-sized match-up are excited, as always. and so are companies looking to highlight new trends in tech. the website whosgonnawin.com for instance, has been tabulating fans daily twitter votes. each night, the winning team gets a display of its colors atop the empire state building. last night the honor went to seattle. a number of companies also have rolled out online previews of super bowl ads, hoping to maximize the return on 30-second commercials that cost $4 million apiece. last year's broadcast pulled in more than 108 million viewers, but the n.f.l. hopes to expand past the television market. this year, online viewers can see a live stream of the game on foxsportsgo.com or the company's i-pad app. some verizon i-phone users will watch using the n.f.l. mobile app. it also gives pop-up alerts on events and retail promotions, around manhattan and areas near metlife stadium in new jersey. tiny beacons transmit the alerts, based on the location of your cell phone.

hari sreenivasan has the story. >> reporter: ground zero is this freedom industries plant that makes chemicals for the mining, steel and cement industries. state inspectors say a foaming agent used in coal preparation leaked from a 40,000 gallon tank yesterday. some of it overran a containment area, and ended up in the elk river. an estimated 300,000 people are affected in nine counties, many of them reporting a smell like black licorice. emergency hotline centers like this one are fielding calls. >> we've had some complaints about eyes burning, things of that nature. best advice is to stay inside right now until they get this taken care of. >> reporter: for now, people are being told to avoid using tap water to bathe, drink, cook or wash clothes and dishes. jeff mcintyre heads the charleston water treatment plant. he says the chemical is not especially toxic, but it's not worth taking a chance. >> we don't know that the water is not safe. but i can't say that it is safe. >> reporter: testing shows contamination levels in the river are already falling, but mcintyre says it's too earl

hari sreenivasan explores that from our new york studios. >> i'm joined now by mike pesca from in additionlic radio, the sports correspondent and he brings us up to speed. so if people haven't been paying atension wa, were the dehail shall did -- details of this nfl settlement between players that was announced a couple days ago. >> right, so in august they said there was this settlement, big dollar value was attached to it but who would get what. so that is what this next step details. mostly what they've done is taken ail ams that could occur from head trauma and assigned a dollar value to it. there are a few moving parts of this. one is what is the ail am. so als, lou gehrig's disease, if you are a player who played in the league for four, five years, you're 45 years of age or under and you have als, you get $5 million. then there are sort of lower grades, so if you had type ii demeant ya, you would get less money, i think $3.5 million. also, if you are an older person you get less money. the idea being the payment is made in one lump sum, so over the course of your life, you'll need le
