frozen c 2 has played a key role in trying to save many nearly extinct species a porpoise and a right nasir might not seem to have that much in common but scientists here at the frozen zoo at san diego zoo global are working to save the noise. they're in white right now and techniques they developed could act as a blueprint to save the kita we are pretty confident that if we get a good quality sample will be able to grow and successfully freeze the cells that's going to tell us more about the vicki it's going to say something about its population history it will provide may be. very useful information about whether there's enough genetic diversity in the remaining population to allow it to recover and expand all of a writer is director of the frozen soup it holds more than 10000 living cell cultures if nothing else works the frozen samples would become a last resort for an extinct species the vicky is such an endgame at the end of the day all we may have are cells and we mustn't though. ignore that. we're engaging in a. in an enterprise that we don't know ultimately. time is running out for

this is a case perhaps where history has come down more on the side of nasir than herblock. for me what stood out in 1967 was how important it was to look out for consumers, whether they were people purchasing automobiles or people who were smoking cigarettes or eating tainted meat. mr. block did a series of cartoons that highlighted the work of individuals in promoting better consumer regulation, better safety for americans. could he have drawn this cartoon today? perhaps. i'll let you be the judge. mr. block had suffered a heart attack in 1959 and quit smoking. and he never gave up fighting about cigarettes after that. he hated cigarette smoking. he hated what the cigarette industry was doing to people to encourage them to smoke. here he showed the federal trade commission valiantly attempting to fight advertisers in order to give more controls over what they could say, more truth in advertising about what was in the products that people were smoking to protect consumers. so most people remember ralph nader for unsafe at any speed. but in 1967 he took on the meat industry

nasir in pennsylvania. >> caller: booyah, jim. >> how are you >> caller: i'm good. big fan of the show. thank you for taking me call and i love your book "get rich carefully". >> thank you. >> caller: i'm looking for advice on how to determine a price for a stock if i'm looking to start a core position given how important cost base averaging is. >> i think it is a great question and the reason why it is a great question is that a lot of people feel like they want to draw a line in the sand they want to make what i call a statement buy or in a position where they got rid of it, they bought it and then put it away that is why i say take into account human frailty. the most i ever liked to buy at one point is half of my position i prefer to buy a quarter. if the stock goes higher, well what a terrible high quality problem. if it goes lower, you have room to buy and i like to buy in stages and in all of my books i talk about stage buying don't be overconfident do it in stages. brian in new york. >> caller: hey, jim, how are you. >> i'm fine. how are you doing? >> caller

now i live in nasir. my husband loves what he does. he does it well. and i'm a painter, so every place i go i have new things to paint and new subject matter. we think it's important work. so we keep going out. >> well, i chose my next job very carefully. i left washington. i actually went to new york city. that was one of my assignments. we have something called a foreign press center in new york city. and we work with resident and visiting foreign correspondents. our busiest season is of course during the u.n. general assembly. but that was an opportunity to sort of feel out what was going to happen. and whether this was something i wanted to continue with, what other options were out there, if there were. and i found that actually i really liked what i was doing. and i liked the possibilities of what i could do in addition -- more in educational and cultural exchange work, which i think is so vital to all of our interests worldwide. >> yes, sir on the side, please. microphone is on its way. >> thank you so much. i think to say thank you for sharing.
