dr. sanjay gupta talked with randall mccloy some time later. joins us with the overall health risk the miners face. >> when you talk about a rescue situation like this, as you talked about, the methane gas and the carbon monoxide they can certainly render someone unconscious and impaired short of being unconscious and that's yet rescue mission continues because even if they don't get a response now that doesn't mean necessarily that someone has survived or not in a situation like this. >> reporter: and there is the possibility, too, that maybe they've made it to one of the refuge chambers and they've been waiting there for rescue. >> i just find it fascinating the whole air lock situation so you're dispelling all of the potential toxic gasses which eliminated the rescue efforts and had the fresh air for a period of time. who knows. >> as it was described. it was sort of like a room equivalent of the inflatable slide and it sits tight, and it inflates into an emergency room where 36 people have enough supply to survive for four days. >> people t

dr. sanjay gupta is with another hunter. but he, too, is finding his traps empty. >> it really gives you an idea of just how hard it is to actually get even a little bit of food. diddy, who is trying to provide enough food for nine people tonight, he doesn't really care what he gets at this point as long as he gets something. i can tell you, we still have a long ways to go. it is hot, it is humid, it is a lot of work. >> hunters have to keep going deeper into the forest but that is where hidden danger lurks. forest animals are a reservoir of viruses. microscopic pathogens living in the animals' blood. some are harmless but some are potentially deadly when passed to humans. >> individuals have been infected with these viruses forever. what's changed, though, is in the past you had smaller human populations. viruses would infect them and possibly go extinct. viruses actually need population density as fuel. >> dr. nathan wolff is a world renowned epidemiologist, a virus hunter. he works in these forests, tracking what he calls

dr. sanjay gupta is a practicing neurosurgeon. he'll be joining us in a moment. and in los angeles, carlos diaz, syndicated radio host and former correspondent for "extra." what's the latest, carlos, on his condition? >> well, the latest, of course, is that brett michaels will be going -- undergoing tests all week long as doctors continue to try to find the source of the bleeding. there have been several reports that he is out of the woods. that is not true. he is still listed in critical condition as doctors continue to look for the source. he suffered a major brain hemorrhage thursday, was taken to the hospital. he's going to undergo more test this is week. he said that the pain while he was headed to the hospital is like a baseball bat hitting him in the head over and over again and doctors describe this kind of pain as a thunder clap headache. >> larry: is he in a coma? >> no. the reports are that he is talking. he has slurred speech. he does have some double vision and some dizziness. but he is talking. reports this weekend were that he was talking this week

dr. sanjay gupta reports that new york city has a program to create the next generation of tree keepers. >> reporter: bronx teenager fabian vasquez comes home after a day of hanging with his friends. they were hanging 60 feet in the air. it's all part of new york city's million trees training program. >> it's an effort to take kids known as disconnected youth, connect them with employment possibilities, connect them with the environment. in that sense it's a combination environmental program and jobs program. >> reporter: more than 30 young adults participate, learning urban forestry and nature restoration. and while tree climbing is physically demanding, it's the mental and emotional challenges that initially need to be overcome. >> i was scared, i was scared. i told them i couldn't do it. that's the one thing they kept on saying, stop saying you couldn't, stop saying you couldn't, you can. and that's what they did. look at me now going up. 80, 90 feet. >> reporter: but does a city known for its asphalt jungle need to train its citizens for green jobs? >> our city's parks department man

dr. sanjay gupta. apparently, new drugs being looked at tichlts not on the market yet.why are we talking about it? >> getting right to the chase. >> i'm getting right to the point. >> if you have never had a migraine, it's terrible. >> they just knock you out. >> usually, one side of the head, very debilitating. i can often go blurry. all sorts of things. drugs either don't work at all or if they work, they only work for some people or they have significant side effects, which is why in this sort of industry of neuroheadache community, they have been trying to find new drugs. one of the other issues is that triptans, which is a class of drugs, the most common. they constrict your blood vessels. so if you have heart disease or if you have had a risk of stroke before, your not going to be able to take these medications either. they have been looking for a new type of medication that works in a totally different way that can alleviate pain in people who have simply had no options for a while. that's what the specific drug is about. it is called telkajpan. developed by merc

dr. sanjay gupta. dad, here, look at this. your p.a.d.r legs causing you pain. ok. what is it? dad, it more than doubles your risk of a heart attack or stroke. you'd better read about plavix. if you have p.a.d., plavix can help protect you from a heart attack or stroke. plavix helps keep blood platelets from sticking together and forming clots- the cause of most heart attacks and strokes. talk with your doctor about plavix? i'll do it. promise. (announcer) people with stomach ulcers or other conditions that cause bleeding should not use plavix. taking plavix alone or with some other medicines, including aspirin, may increase bleeding risk, so tell your doctor when planning surgery. certain genetic factors and some medicines, such as prilosec, may affect how plavix works. tell your doctor all the medicines you take, including aspirin, especially if you've had a stroke. if fever, unexplained weakness or confusion develops, tell your doctor promptly. these may be signs of ttp, a rare but potentially life-threatening condition, reported somet

dr. sanjay gupta, as well, medically speaking, could the four remaining miners still be alive? and ed lavandera praying that that answer is yes. john, you actually talked to the ceo of this mine. let's go ahead and listen to his defense as you grilled him on production, profits and mine safety. >> wield disagree in terms of the condition of our mines. a number of violations can depend on what area you're operating in, who the inspectors are and a whole host of issues and we're a big producer, but the truth is we're doing a better job in our mines typically than what we observe otherwise. >> are you suggesting that you've been unfairly singled out? >> i'm not suggesting anything. i'm saying we know because we hire the top people from graduate schools. we do a good job of keeping our mines in good shape and we're very open with the regulators and very dedicated to safety. so i have no belief that we are not doing as good or better job than others. >> in the wake of the sago mining disaster and you know this well, mr. blankenship. new regulations were drawn up with the miner act,

dr. sanjay gupta. >> this is generating a bit of buzz and quite a bit of controversy by r.j. reynolds, camel products called orb stick strips. look at them. just looking at them you get some idea of why there are some buzz and some controversy about this. they look a lot like candy. these are nicotine candice or devices in some way that are not intended to help someone stop smoking but really to give them a kick if they have a nicotine craving. that's the way they are marketed. one of those little orbs, as they're called, as enough nicotine to approximate a signature brett. therein lies a problem. if a child were to get their hands on this, a child between the ages of 1 and 4, for example, and eat one, just one, they would probably feel pretty sick, nauseated, they they have vomiting, have a headache. if they were to eat civil, up to ten, this could potentially be lethal. again, you're carrying around products that could potentially be problematab m problematic. we took some of those criticisms directly to the makers of this product and said, what of it? you have these nicoti
