first of all professor, what you teach at johns hopkins? >> guest: i teach racial politics and urban politics. >> host: what are those? ask you when you think about it racial politics, concerns or competition over scarce resources between different racial groups and can include such aspect is how different racial groups attempt to kind of define what race is and how it works and how through that definition may end up creating a dynamic where some groups have a lot of resources and some groups have fewer resources. black politics think about racial politics is competition between different racial groups. black politics comes for me to competition about what the black agenda should be about how we define what blackness is. urban politics is about the competition over scarce resources within a metropolitan environment in between different metropolitan environments. >> host: is very black agenda? >> guest: some people think there is. some people think there should be. i would say instead of a black agenda, there are black agenda is. different s

george mason, johns hopkins is one of the most notorious. my alma mater umc chapel hill is a good one. they all have something that students expect that you can go and take a course in writing which seems to be projecting yourself on the paper. >> host: if you were going to teach a course on writing what would be two of your goals? >> guest: i've done that. two semesters at the university of north carolina greensboro back in the late 60s i gasped. in two semesters at johns hopkins and what they call the writing seminars back in the early 80s. those cases i taught at opinion writing. attack editorials writing book reviews, writing columns expressing opinions in intelligible and coherent way. so that is what i would do. my plans for retirement to not include teaching. i didn't like it very much. if you are teaching a class, where students hand in papers, it's that you have good students. the truth of the matter, if you teach a seminar at 15 kids and you have to good students, you are very lucky. they may be bright, but they're not interested,

cristian tomasetti is one of the authors of the report and a bio- mathematician at johns hopkins. me now from baltimore. thank you for joining us. it seems important, first, perhaps, to explain what you were looking at. what does bad luck or chance mean when it comes to getting cancer? >> yes, what it means is that every time a cell in particular a stem cell every timeit divides, a mutation can occur and can hit the dna of this cell. if that mutation happens to be in a gene that is the key regulator known to be associated with cancer -- so let's say a bad mutation that may lead us to cancer. so that's what we meant for bad luck. >> reporter: so were you and and other researchers surprised to find that bad luck in a sense played such a large role in so many cancers? >> yes. i would say that i think it's been known that luck together with environmental factors like smoking or sun exposure as well as inherited factors are three of the components and i think what was surprising and expected, in a sense, was how large, how important this component of the bad luck turned out to be. >> r

marty mccarey, a physician at johns hopkins as well as a cancer surgeon. the reason why people develop cancer has been a mystery. a lot of people say it's her it tri and lifestyle and someone who smokes lives to be 90 and someone who lives a healthier age gets cancer at the young age. >> it's been a big dilemma for people not just in medicine but the general public, why someone who lives a bad lifestyle can live cancer free and someone who eats well and avoids uv light can develop cancer early in life. this new study shows that it may be related to factors that are totally random about 65% of the time. that is the normal cell growth can just randomly go wrong and lead to a mutation that causes cancer and about 65% of the cancers out there. the other 35% may be more susceptible to what we call the environmental or lifestyle factors. >> how do they do the study? >> what they did they did a pure mathematical model, calculated the number of cell divisions in 31 different tissue types and they found when there were more cell divisions or opportunities for mutat

. >> scientists at johns hopkins say responsible is only part of the time.he rest is up to chance. scientists at johns hopkins university and the bloomberg public health, say cancer has more to do with lifestyle than bad luck. >> science has told the layperson what many of us in oncology have speculated about and believed for some time. and that is that some people can do everything that we say you should do to prevent getting cancer yet you're still going to get cancer. >> reporter: our cells naturally divide and replicate themselves. but sometimes those cells mutate and become cancer cancerous. they found that two-thirds of them divided more frequently increasing the chance they'd mutate and develop cancer. the research concluded remarkably, this bad luck explains more than hereditary and environmental factors. that influences only about a third of cancer types but some doctors caution this doesn't mean that people shouldn't take care of their bodies. smoking is still linked to lung cancer and overexposure to sun is linked to skin cancer. >> people who smo

the team at johns hopkins university says the answer lies in the way the body regenerates. old, tired cells are constantly being replaced with new ones made by dividing stem cells. each time a cell divides, there's a danger the letters of its genetic code will become jumbles, leading to an increased cancer risk. overall, the study found that around 65% of cancers were caused by random mutations that cannot be prevented. it's down to biological bad luck. but, the research concluded that a third of cancers, including skin and lung cancer can still be prevented by lifestyle changes. >> if there's anything wrong with our diets or exercise habits and so on in order to not increase our risk of cancer but this just says that there is a component that's bad luck. that is not our fault. and it just happens. >> reporter: writing in the journal of science, the report authors say that as most cancers can't be prevented, there should be more focus on spotting them early. kate bee, bbc news. >>> steven gerrard, captain of the english premier league football team liverpool has announced h

. >> reporter: researchers for john hopkins say the genetic mutations that crop up as the stem cells divide are what they call the major contributor to cancer overall. this is a math equation coming up with the bad-luck theory. they analyzed published papers looking at the number of stem cells and the rate of division among 31 types excluding breast and prostate cancer. and then they compared the risk of developing cancer. only one third of the cancers in the tissues can be blamed on factors like smoking so 2/3rds come from random mutations in dna. the authors say this doesn't mean you should go wild with lifestyle choices. one professor added he hoped it puts more focus on early detection of cancer. cancer of the lungs, skin and other tissues are tied to sun exposure and smoking and people should remain vigilant about quitting or cutting back the behavior. the new research is intriguing but people have concerns it was weekend by the lack of data on breast and prostate cancer. >>> the town of paradise california is anything but a paradise today as winter weather slams parts of the we

jeremy green who is a professor of medicine here at johns hopkins, university. dr. greene what's the definition of a generic medicine? >> guest: oh a generic medicine is supposed to be the same as a brand name medicine. we think of them as identical they are the same molecule, they're supposed to perform in exactly the same way except that they're not exactly the same. we want them to be cheaper. we look at a generic drug as a way of gaining more access and affordable price to medicines which, when they're previously available only by a brand name under a monopoly are much more expensive. so a generic drug in some ways is a concept it's a very contested object, and it's a very recent object over the last 50 years. it's become a key point in attempts to help american health care be more affordable at the same quality. in some ways it's been remarkably successful as a set of policies. in 2014 more than 84% of all drugs, prescriptions filled at the pharmacy were filled generically. trillions of dollars have been estimated to be saved because of substitution of cheaper
