experts at john hopkins university in the u.s. say satellite images from wednesday indicate additional activity at the poongkye-ri nuclear test site and noticed an increase in the movement of vehicles and materials near what are believed to be the entrances to two test tunnels. the images show vehicles that could provide secure communications between the site and other facilities. similar equipment was spotted before north korea's third nuclear test in february 2013. >>> now before obama headed to seoul he was in japan. the u.s. president had hoped to reach an agreement with prime minister shinzo abe on a free trade deal for the asia pacific but their negotiators couldn't see eye to eye. nhk reports. >> reporter: barack obama came to tokyo hoping he might be able to give negotiators a bit of a push. he'd seen them struggle for months to move forward on their part off the transpacific partnership, but he left tokyo without seeing much progress. >> all of us have to move out of our comfort zones and not just expect that we're going

what i would say and share with you as johns hopkins university's there's a skull surgeon there and he uses 3-d printing to create 3-d prints to do preop planning. so before the team ever goes into the operating room exactly what the cuts are what is removed where the samples are and everything is done in order to simplify that process. i think that's fantastic. the doctor is working less hours in a stressful situation the patient is under anesthesia less time and operate and cost are a huge contributor to health care costs and that is lower. this is disruptive technology. that is going to upset the apple cart in many directions so the business model for hospitals is now going to be disrupted. they may not be so happy about operating room costs operating room times been declined because now they have to rework the numbers again but health care, medical is one of the first enter shays to engage in it. >> so we can actually for instance if there were someone who needed plastic surgery a plastic surgeon could use the x-rays and nowhere the cuts are going to be and know how they are going

. >> reporter: a former world bank official, johns hopkins professor, phd from columbia university, whoan in 2009. and i think at around 3% of the vote. did very, very poorly. but this time has managed to really galvanize a huge number of afghan voters. in part by choosing a controversial vice president, a warlord named dostin, very, very popular with certain ethnic groups, but has a sort of sketchy history. the other candidate who is doing very well is dr. abdullah abdullah, came in second to karzai. and abdullah is the most prominent tajc candidate at this point. and it will do very well in the first round. the question is, in a country where the majority of the population are ethnic posh tunes, will abdullah and tajc be able to win the election. that seems unlikely. >> so you have one candidate favored by karzai, the one trailing in the polls, and a vice presidential candidate that's a woman. >> reporter: yeah, karzai has not publicly articulated any preference. there is widespread perception that he's favoring dr. sewell, his former foreign minister. but it's unclear exactly what th

research i talked to a couple of extremely intelligent researchers from the university of -- in a couple of researchers from johns hopkins. they took a dataset from 600,000 tweets. geo-type sweets from here in new york and they analyze them semantic weight to train a computer program to know when someone was tweeting about how they were feeling, specifically how they were feeling. it's actually a difficult problem computationally because we use terminology that suggests sickness and thicket of ways. i have fever or i'm sick of justin bieber. so you have had to train the computer program to distinguish between figurative illness and actual bits of illness. >> host: at home today feeling feverish. >> guest: writes so all the strange nuances of the computer language. then they looked at where people were in where they were going and who they said they would be within how long. co-location is a big component in based on this they were able to predict 18% of all the person-to-person flu transmissions between the people they were looking at. they predicted 18% of one person having another person the flu among this group. that'

workers at johns hopkins in baltimore pushing for a $15 floor. and now for the 62,000 workers at the universityl center. it says that the workers really need $15 an hour. it points to studies showing that a living wage for one parent and one child is like $17 an hour. and it says $12.81 an hour doesn't cut it. >> so we're talking about 62,000 workers here? >> yes. some of them are doctors and nurses and they're making well above $15 an hour. >> sure. >> but the sciu says it's trying to unionize 24,000. the hospital says says no, no, it's really only around 6,000. my sense is the sciu is really trying to organize at least 10,000 cafeteria workers, nurses aides, janitors, you know, secretaries, and in many ways, i think the sciu's effort is really only now gathering steam. they're facing very intense resistance from the hospital. i think a lot of workers are very scared to stick their necks out and voice support for the union. the board has brought some charges against the hospital system for illegally firing some workers, managers at upmc say that the sciu really isn't getting much traction, tha

couple of extremely intelligent researchers, adam tex university of rochester at the time, now with google, and a couple researcher at johns hopkins. they took a data seat of 600,000 tweets from here in new york, and they analyzed them semantically to train a computer program to know when someone was tweeting about how they were falling. specifically how they were feeling it's a really difficult problem conversationally because we use terminology that suggests sickness all the anytime figurative ways. look i have bieber fever or sick of justin bieber. those seem lake they should be the same thing but they're not. so you had to train the computer program to distinguish between figurative uses of illness and actual use of illness words, and then -- >> host: at home today feeling -- >> guest: right. >> bieber-ish. >> guest: right. so all of the strange nuances of human language, and then they looked at where people were, where they were going, who they said they were going to be with and to how long. location is a big component. and based on this, they were able to predict 18% of all the person-to-person food transmissions that occur

john hopkins eye institute and joins me today to talk about his experience and mission to and blindness. also joining me, jean bennett, steven schwartz, eberhart ofnner, and carla shatz stanford university and once again, eric kandel a nobel laureate and a howard hughes medical investigator. toegan with my friend eric give me an overview of our subject tonight. >> the last program we did was approaches to deafness. tonight we are going to consider lines miss. as is the case with deafness, blindness is not a life threatening situation but it is disabling. in some ways it is more disabling than deafness because there are a number of important conditions for which there is no treatment. now, why is that so? deafness, the sensory organ for vision, the retina, which is evident in the lower image, it lines the inside surface of the eye. oft is the most complex set organs we have. in fact, it is not a proof real organ. it is actually a part of the central nervous system. as a result, it has the complexity of the structure. it is not uniform. it has a small area that is clear which is called the macula. area of greatest visual acuity. so if i turn my head towards analyzes youra features. unfort

john hopkins international. he is joining us from washington as i just said, good to have you with us. how would you evaluate the support that he has at this point? >> pretty universalfrom the general point of view, but pretty bad in terms of a really an election turn out, and electoral support. the people like him, they see him as a dead man, and there is no real opposition. the opposition candidates come from his own party, and they are more of the same without the same pizazz and scries ma that he used to have, before he had his disease. the turn out is bad. it is about two-thirds of the turn out before, and in previous elections and it is a poor show. >> are you saying that he is going to win this election hands down? ive, i would put lots of money on that. >> what about the support he has on his inner circle right now. >> well, his inner circle are his own picked inner circle. his security chief, his newly appointed to replace the old security chief. he has taken the military circle under his control, but outside of that, there are splits within the military, and certainly splits within the established political groups. ole garrya is run by the junta. an anonym

university that is doing bone implant thing, but i think it is in texas. biomedical engineering is huge, yes. what i would share with you is that at johns hopkins, there is a surgeon there. create 3-d printing to preop planning. they know before they ever go into the operating room exactly what the cuts are, what is removed, where the staples are. they simplify the process and that is fantastic. the doctor works less hours and able stressful situation. the operating cost is a contributor to health care cost and that is lower. this is distracted technology. that will upset the apple cart. the business model for hospitals is now going to be disrupted. and they may not be so happy about operating room cost. the time has declined because they have to go back and rework the numbers again. medical is one of the first industries that have engaged with 3-d printing. >> great. so, if there was somebody who needed plastic surgery -- they could use 3-d printing -- they could use x-rays and snow were the cuts are going to be and how to repair this patient's face? >> absolutely. >> they also use it for surgical guides. they put the print rate on the body an
