remembering the oklahoma city bombing." tomorrow night, anthony bourdain brings us a new show with no boundaries. he and his crew traveled to libya, myanmar, peru ander more at 9:00 eastern on sunday. that will do it for me. "newsroom" continues with don lemon at the top of the hour with the top stories. keep it here for sanjay gunpo t gunpoint -- gupta, m.d. >> you may have heard about a deadly flu strain in china and whether the united states is ready to handle an outbreak. the cdc will join us. and living longer with fish oil. one of the few supplements i take. and the best foods to eat and what to avoid. let's get started.

first i want to show you something truly remarkable. a bionic limb run by a household technology -- an iphone. we'll get a demonstration in a moment. first i want to introduce you to the first recipient of the hands. a young father who lost the use of his hands after being electrocuted. march 1, 2008. that was the day jason's life changed. he was riding his four-wheeler when he came in contact with a downed power line. next thing he remembers, waking up in the hospital three days later. he was alive but both of his hands were gone. they had to be amputated. his focus immediately making

life with prosthetics as normal as possible. the first is the i-limb revolution now available to the masses. the uk develop rs say it is the closest thing to a real human hand. unlike most conal prosthetics it has five individually powered fingers including a fully rotatable thumb. the new app technology allows for 24 grip patterns, movements many of us take for granted like this. a tripod grip to pick up a pen. the skin over the prosthesis

helps him use the app and he can grip to use things like his electronic grill. jason joins us now. welcome to the show. >> thank you very much. do you have pain at all or are you recovered? >> i'm recovered. >> this is a handshake. fingers coming all the way around. you got it this week. how is it going? >> i love it. these have motorized thumbs. it has an app that comes with it so you can do several different grasp patterns. it gives me the ability to do more things that i want to do. >> looks like it takes full advantage of -- we take for granted dexterity in the

fingers. these are two of your other hands here. i think you were explaining that this this basically has the pinch here between this. that's basically it. you call this the working hand. it opens up. doesn't do much more than that. >> that's it. >> this is the app here. do you mind if i take a look? >> no. >> let's see here. so if i want to -- you have -- >> let me make sure. >> we'll have you control it a little bit to start. >> i have to use this. >> you're picking up a stylus. is that something you could have done before? >> no. >> that's pretty fine movement there. >> so i would get this into a grip form i wanted. close down on it. i have wrist rotators to rotate all the way around. >> you're doing this on your own. your hand goes all the way

around. okay. >> these also have different -- there are 24 different grip patterns. you can also customize one also. so here is one i have customized. i don't know if you know what that is. that's for louisville. >> as a michigan guy, i know it too well. >> you can play with it if you would like. >> all right. since you have louisville right on there, i love it. let's see. we have candies here on the set. let me see if i can find one to help you open it up. >> you put it in that mode. i have wrist flexion. so i can flex it. i can pick up something that small. >> that's amazing. what is it like for you to be able to do that? how big a deal? you got the app. you have fine dexterity.

>> a lot of things you take for granted in life. to pick up something small as this or, for instance, i have kids. to be able to hold my kids hands again is a lot holder because this forms to their hand. in my eyes that's huge for me. it's definitely interesting how you can do small things instead of asking somebody else to do it for me. >> thanks for joining us. >> thank you. next up, bird flu. we know it's killing people in china. the head of our centers for disease control is worried about it. we asked him to come by and ek plain what's happening. s! wow. it's the honey, it makes it taste so... well, would you look at the time... what's the rush? be happy. be healthy. to try on these amazing depend silhouette briefs. oh, it's cheryl burke! who's this guy? security. cheryl, hi! i know you don't need one

jamie mcmurray: a boy born in joplin, missouri, was fascinated by anything with wheels and a motor. the odds of him winning both the daytona 500 and the brickyard 400 in the same year? 1 in 195 million. the odds of a child being diagnosed with autism? 1 in 88. i'm jamie mcmurray, and my niece has autism. learn more at autismspeaks.org/signs. it started like this. on the last day of march, three people hundreds of miles apart sick with a strain of flu that had never infected people more. in less than a week a third of

the people who were sick had died. hundreds of health officials around the world went into scram bable mode. the scenes are eerie. masks for protection. spraying to kill an unseen danger. >> the public is concerned about the information regarding those in close contact with those infected. we are tracing many close contacts and they are all under strict medical observation. >> this time the danger is h7n9 named after the key proteins that make up the virus. it is a known type of bird flu, but never before has it infected people. something in the virus has changed. something is different. a quick explanation is in order here. there are different strains of the flu virus. they mutate constantly. that's why we need a different shot every year. the virus changes by adding new genes and dropping old ones. the natural home for influenza is birds especially poultry. it also infects mammals like pigs and also people.

the virus is constantly adapting to different hosts. remember the 2009 pandemic, h1n1, that originated in mexico. more often than not new flu strains arrived in southeast asia because there is a concentration of poultry, wild birds, pigs and people. all living in close proximity. >> there is a lot we don't know b about the virus and we are actively tracing its origin. >> testing has found the h7n9 virus in chickens and pigeons. chinese authorities are killing chickens and other possibly inif he canned birds as a safety precaution. questions remain including a big one. could the virus be passing from person to person? so far the answer seems to be no. >> there has been no person-to-person transmission and no link between any of the cases so far. >> joining me from the cdc campus is the director of the

cdc tom friedan. we have been talking about the strain of flu. why are you so concerned about it? >> on with one hand we are reassured because there is no person to person transmission documented yet. we have great discussion with the authorities and work on getting more prepared for stains of flu or other pandemics. it's a strain of oh influenza that causes severe disease. it doesn't seem to cause disease in the birds. so we can't identify it in birds and stop it in the animal hosts. it does have some aspects that suggest it could evolve into something that could spread person to person. >> should people in the united states be concerned? >> there is nothing different that the average person in this country needs to do. there is a lot we are doing to make sure we do everything in our power to be as prepared as possible for every scenario that

could happen. that's what we are doing day in, day out. >> putting it all together your level of concern when you compare it to previous novel viruses, how would you rate this? >> we are tracking it closely. we know that influenza can cause an enormous amount of suffering and dislocation. this strain seems severe. we are doing everything we can to be prepared. one thing we are looking forward to more in the future is to go deep into the sequence and understand better what all of the different genetic changes mean. we have new technologies that are exciting and will allow us to do it better than ever. >> why don't you give us an idea of what it means. you have examples of the older technology and the newer. what can you do now that you couldn't do then? >> when i began at cdc we had

begun looking at different microbes. we had things like this. they gave you a blurry sense of whether organisms were the same or different. they took weeks. you often had to compare them by hand. it was very enact. today we have things like this. this is a way of sequencing an entire je gnome in just a few hours. in fact, the je gnome of more than one organism in a few hours.genome of more than one organism in a few hours. putting it into the computer, putting the puzzle pieces toegts and figure out if it's connected or evolving to better adapt to the human host. so we are beginning to do this for h7 and other organisms. it opens a new way to protect americans better by finding threats sooner, stopping them quicker. >> i'm glad you're on the job. i know we'll be talking a lot.

thank you. >> thank you very much. >> still ahead, perhaps the most convincing evidence that eating fish can lead to a longer healthier life. things can become major victories. i'm phil mickelson, pro golfer. when i was diagnosed with psoriatic arthritis, my rheumatologist prescribed enbrel for my pain and stiffness, and to help stop joint damage. [ male announcer ] enbrel may lower your ability to fight infections. serious, sometimes fatal events including infections, tuberculosis, lymphoma, other cancers, nervous system and blood disorders, and allergic reactions have occurred. before starting enbrel, your doctor should test you for tuberculosis and discuss whether you've been to a region where certain fungal infections are common. you should not start enbrel if you have an infection like the flu. tell your doctor if you're prone to infections, have cuts or sores, have had hepatitis b, have been treated for heart failure, or if you have symptoms such as persistent fever, bruising, bleeding, or paleness. since enbrel helped relieve my joint pain, it's the little things that mean the most. ask your rheumatologist if enbrel is right for you.

[ doctor ] enbrel, the number one biologic medicine prescribed by rheumatologists.

got some fish for life today. a new study found older adults who eat fish reduce their risk of dying from heart disease by more than 27%. a lot of the credit, they say, goes to omega-3 fatty acids. one of only 200 nutrition specialists in the entire country. welcome back to the show. we talked about this quite a bit. i want to jump in with this. you have been on several times

talking about the benefits of omega-3s but some of the studies are conflicting. what make this is one different? >> i think what's interesting about the study is first of all it was done in healthy older people. so this is not people who are sick with heart disease. it's just like you and i -- healthy. we are not older yet. secondly they were not taking fish oil supplements. this looks just at fish intake. most importantly, researchers measured blood levels of omega-3 fatty acids instead of relying on dietary recall. this is a much more accurate indication of how many omega-3 fatty acids they are consuming on a regular basis. >> fascinating. you're right. most of the studies are done by questionnaires. it's hard to remember what you had yesterday let alone two weeks ago. >> absolutely. >> according to the study people with the highest levels of omega-3s in the blood did the best. they lived two years longer and it comes back to the question.

how much should you be getting and the best way to get it? >> that's a great question. based on this study, the researchers think that sweet spot, so the benefits are most when somebody goes from no consumption up to 400 milligrams. this is a modest dose. the average american takes in about 150 milligrams a day. we know we need to go up, but you don't necessarily need to super dose like our tendency is when anything is good for us. >> so 400. is there a way to put that into the context of food? in this study they were talking about eating fish as opposed to supplements. >> 400 milligrams is on average two servings of fish a week. the american heart association is right on track with their recommendations for eating fish at least twice a week. >> do you think some of this is because if you eat fish you are not eating, you know, other things ta could be a problem -- red meat and things like that? >> well, it's interesting. they looked at confounding

variables, so other explanations. it really does seem to be a benefit of omega-3 fatty acids. by looking specifically at the omega 3 fatty acids in the blood they could attribute those benefits. i think people who tend to eat the most fish have a healthier lifestyle. the people in the study did seem to be healthier which is even cooler. if we could get healthier people living 2.2 years lock longer that's a win in my book. >> i love having you on. we talked about this last time. fish oil is one of the few things i take. there is a lot of studies out there. this is another one that offers more benefits. thanks for joining us. >> me too, by the way. >> thanks. you may not know this but this week marks the 71st anniversary of the death march that followed one of the worst military defeats in history.

few survivors are alive today. lester tenney lived to tell the story but has turned his tragedy into joy for others. lester along with his wife and friends are packing boxes to ship over seas. he's the founder of care packages from home, a volunteer organization that sends goodies to servicemen and women in iraq and afghanistan. since it began five and a half years ago te eh and his buddies shipped socks, deodorant, snacks, holiday items such as peeps to 150,000 troops. >> we have zero employees. we have zero payroll. we have zero expenses. every dime we collect goes to the troops in the way of care packages. >> although it's labor of love he has a more personal reason. back in 1940 he enlisted in the national guard. he was then transferred to the army division and ended up in

the philippines. then japan attacked pearl harbor. a day later japan invaded the philippines. the u.s. had to surrender. on april 9, 1942 one of the worst episodes in military history began. american soldiers were forced to march to a p.o.w. camp, 80 miles away in 100 degree heat without food or water. >> it was called the death march not just because of how many died but the way they died. >> some were decapitated, others speared. many buried alive because they were too weak to march. tenney carries a scar from being slashed with a sword. >> if you stopped you were killed. le if you had to defecate, you were killed. if you couldn't take another step you were killed. they just killed you for no reason except for the fact that you didn't move. so the whole goal was to, number

one, stay on your feet. number two, keep moving. >> unlike many of his buddies he made it to the concentration camp. because he was strong his captors eventually shipped him to work in the japanese coal mines where he remained until world war ii ended on august 15, 1945. >> that was a feeling of freedom you can't ever describe. >> after the war he went to college, became a professor of economics and wrote a book about his experiences. "my hitch in hell." after he left teaching he and his wife loved to the la costa glen retirement community. he never stopped thinking about his days as a prisoner of war, the loneliness and fear. that's why he started sending packages to the troops. to let them know someone, somewhere is thinking about them. >> when i send a box i put my name in it. so they know where i have been. maybe they do, maybe they don't. the one thing they know is that we care.

>> at 92 now, lesterer is one of the few remaining survivors of the bataan death march. when asked how he survived his answer is inspiring. >> i think my first thought after that was i can't die. because the japanese want to kill me. they are working hard to do it. if i die they win. i was just making sure they did not win. >> just an incredible story. obviously doing so much good for the troops still over seas now. a check of the top stories minutes away. first, chasing life? learning how to put the right foot forward. when you have diabetes...

we are back with sgmd. more than 10,000 runners take to the streets for the boston marathon. inspiring but daunting. i get this question all the time. they say a marathon is likely not in my future, but how do i start to run? keep two things in mind. get a good pair of shoes and start slowly to prevent injury. running shoes are different from everyday sneakers. you will need the support to get the real exercise. everyone's foot is a little different so go to a running store to be fitted properly. at least the first time. then when you hit the road, again start slowly. a good approach is to alternate running and walking.
