charlie: what percentage of people go under anatomical change? we are in a state of flux on an operation that could cost a lot of money. the reason i say that is because insurance companies are waking up to the idea that this is a medical condition. that it is entitled to be billable for surgical and medical aspects of their care can be covered by insurance. it is going to change everything. up until now, people had to save up to have the surgery. it starts from the top down. first, you have to not make it as a mental illness. you have to define it as a physical problem which it is. hiding it as being gay was what freed up people starting to see gay people is not having a psychiatric illness. it was having it removed from the manual of mental illnesses. we will see. the colleges that are self-insured, maybe even the college you went to, his paid by people. if i am going over to some of them and seeing them. charlie: i thank each of you very much for coming. there is enormous interest, as you can see in the publications and also the conversation t

anatomical sex and gender identity. anatomical sex is the body parts associated with sexuality and reproduction. gender identity is a sense of one's self is a male, female or something else. anatomical sex is determined not surprisingly by our genes. genes are ancient chromosomes and we have 23 pairs of chromosomes. half from our father and from our mother. 22 of these are called autosomes. the difference between the fathers and mothers contributions are real but modest. the sex chromosomes, the difference is quite profound. women are xx and men are xy. the chromosomes are really quite different than the autosomes. they had a very important function in determining sex. let's begin with a y chromosome and see how that determines the sex of the male. they are born with a gonad that could develop into testes or ovaries. if there is a y chromosome there, it has a region in it which is called the sex determining region of y. that contains the gene that activates the differentiation of the undifferentiated gonad into the test

let's begin with the anatomical sex. an tomorrowical sex is determined the sur prisingly by our genes genes are arranged in chromosomes and we have 23 pairs of chromosomes, we get half from our father one pair from our father and one pair from our mother. 22 of these are called odozomes and the difference between the father and mother's contributions are real but they're modest. but the sex chromosome, the difference is really quite profound. women are xx and men are xy. the chromosomes are really quite different than the odozosomes and they have a important function in determining sex. let's begin with the y chromosome and see how that determines the sex of the male. we are born with an undiffer yented gofad that can move in either direction either developing into t testes or ovaries. if there is a y chromosome there it has a region in it which is called the sex determining region of yferx. that contains a gene that activates the differentiation of the undifferentiated gofad into the testes. if that y gene is not there

government's attempt to build anatomic weapon to drop on germany to end the second world war. and resulted in the atomic weapons that were ultimately dropped on japan in august of 1945 which did in the second world war i and out of that grew oakridge national laboratory. this was set up originally in 1943 as clinton laboratories. dn have the name oakridge at the time. and the purpose of clinton laboratories was to learn how to produce plutonium which was a radioactive element that could split and release vast amounts of energy just like some uranium can. but they didn't know much about plutonium. it was an artificial element. it had to be created by man. they knew nothing about the characteristics of plutonium. building started in february of 1943. this facility, the graphite reactor as we know it today, was starting in spring of 1943, completed by november of 1943. and came on line as the world's first operating nuclear reactor and in this case, used specifically to produce tiny, tiny amounts of plutonium which were recovered and then shipped up to the laboratory which was pa

jon: it took 4-1/2 months to build this anatomically correct t. rex.e to cut it apart? >> over 30 hours two ruling days for sugar stage blood, and bore and some great memories. jon: i bet. there are so many mysteries. you don't really know whether this thing was warm blooded or cold-blooded, do you? >> i would eat the had i'm not wearing that as a cold-blooded animal. from the way it moved and to its -- it seems to me like it is a giant chicken. jon: has this great back legs and a ferocious set of jaws. the front legs did seem to do much. did you come up with any information through his autopsy about how it used those front legs? >> i fall into the camp of henry fairfield osborn, a paleontologist named t. rex, the turn of the 20th century rolled around, he came up with the idea that it used its arms to age in the act of mating there coupling devices. jon: mating. that is biology. >> this is a family show so we won't go deeper into that. fascinating stuff. i am from denver, not far from where you are now, dinosaur tracks are up there in morrison. >> we

this gives you an anatomical view of exactly how blocked that artery is.omeone at risk, i want to have this test. >> quickly, dr. samadi, bringing you back. this lady has a family history of coronary artery disease. cholesterol, high blood pressure, race. do any of those come into play here? >> yes. sometimes post menopausal women. as a detective you want to look at this patient and say these are the risk factors and i want to find out exactly what's going on in your coronary arteries. once you do that, and you get the score, you decide whether you want the stress test, go to angio, maybe the patient needs stent. i don't think everybody needs this test. be careful. for people who are at moderate to high risk, i like it. >> one risk factor which is cholesterol. cholesterol correlates directly with the plagues in the arteries. if you have a high cholesterol, i would like to do this. with lifestyle change which we've talked about a lot, you can reverse it. it's not always taking a drug. lose weight. >> if you know about this, you can reverse this whole neck n

if you're going outside the confines of just telling anatomically how things work, you need permissionht even want a shadow as parent. i might want to be classroom parent on that day. when you get to the point demonstrating things that can clash with someone's value system. you're not teaching it along with the values. >> they said the kids were not allowed to play with the toys and things up on the shelf. you know don't you remember the guys in seventh grade. the boys would be laughing, joking around. would not have taken it seriously. sandra, here in new york high schools are demonstrating how to put on a condom. what do you think? >> they say it is regular practice and has been for quite some time. i have been told since i'm a parent you will be shocked when your kids are school age what happens in the school. i would be shocked and not trust the system if i found out this happened with one of my children -- until we master mathematics, history, arts, why are we spending time and money? >> whatever happened to algebra right, algebra? come on. >> when you look at statistics pregnancy

and the sensation -- i want to be anatomically correct here -- of your nards coming up into your throat laughter ] oh, yeah, yeah. that's correct. yeah. that's right. that's what that is? >> yeah. >> jimmy: oh, my gosh. and so would you ever do that again? >> i would. you know, i'm not pretending to be fearless. there are things i'm terrified of. but i think you're either afraid of heights or you're not, and i just wasn't afraid. i did get one great bit of advice from a window washer who shall remain anonymous. i said, "you guys go out for four hours at a time. what if you have to go to the bathroom? you know, if you have to relieve yourself?" and the window washer said to me, "i tell my loved ones don't ever walk under a window washing basket in the city." [ audience ohs ] >> jimmy: that's a good lesson, everyone. learn that lesson. >> it's not a refreshing mist. [ laughter ] >> jimmy: i've got to say, you're very talented but you're also very talented at cooking. and very interested in this. "my grandmother's ravioli" has its fourth season starting right now. and why did you do this s

i know -- i know what anatomically and biologically he is and that doesn't change by himself identifying himself. i mean you know his genetics and dna isn't changing but out of respect i'm not going to -- i'm not to -- i'm not going to argue whether bruce jenner is a woman. with bruce jenner i'll treat him with dignity and respect and that's what i said. >> let me go to matt. what is the role? gregory says it's not a large role. what role do the voices that we were hearing and have been hearing about the jenner new identity, what do they tell us about the state culturally of the republican party and how you're going to field a reach can candidate next year who either reflects those views, challenges them or dismisses them? i want to know how you're going to handle this talk. >> well obviously the nation has shifted its views on issues surrounding gay rights rather dramatically. you can see that just in the polls, and you know that's what's great about living in a democracy. it will have an effect on these parties. i think the way rick santorum answered the question is right. as you know

i know what anatomically and biologically he is and that doesn't change by himself identifying himself i'm not going -- as you said, i'm not going to argue whether bruce jenner's a woman with bruce jenner. i'm going to treat him with dignity and respect and that's what i said. >> santorum hasn't said anything this week since that "vanity fair" cover came out. maybe that in and of itself says something, that rick santorum hasn't. but the fact that rick santorum went as far as he went in that interview signals some kind of a change here. >> rick santorum's emblematic of what these candidates are all going through. so he gives that statement to a reporter, that if caitlin jenner says she's a woman, she's a woman. and then he had to talk to breitbart, the conservative news site to walk it back and soften his comments went up on facebook with another comment, gave more interviews explaining that though that's his personal view, he's not advocating for any policy change. this is why no one wants to interact or engage. they thought this was going to be a political fight this summer on same-se
