but this guy at caltech can tell you speak up we can hear you. here is one of my favorite bits of trivia where researchers have discovered the micro biome once the body to live perk a remember the immune system has a terribly difficult task to deal with all the pathogens and microbes but it turns out the micro biome is sending signals across your gut lining we thought was so sealed we call it immune privileged that nothing got in or out bacterial cells till your immune system. to instruct the cells in your immune system to ramp up or slow down. that is the basic answer to your question. there is a relationship but it will be exceedingly important one - - potent and a healthy got in your immune system and the river that runs through it. remember i said it is sending signals that say attach? or stop? i just want to make clear this conversation, a big part of the molecules in your immune system are designed to put the brakes on the behalf are designed to stop it. we would not be here today without the immune system to put the brakes on. 's for mac i

because of its association with caltech, it only had a quirky academic feel. and it still does today. it still feels very different. despite working in such a progressive place, the women of course were still subject to gender norms of the day, and one of those that i found most surprising were the beauty contests. the lab held miss guided missile, later renamed the queen of outer space. women from all over the lab would compete in these contests. my favorite beauty contest story 1964, as part of the ranger series of missions. missionsa series of whose goal was to send the first camera to the moon in order to the first close-up images informlunar surface and possible landing sites for apollo. 1964, this was proving impossible. there had already been five failed missions. was a real feeling that if we can't even send a are weto the moon, how ever gonna get astronauts there? four ranger sets, the director of the laboratory, flew d.c.o he sat with president johnson on an open phone line to mission at the lab in pasadena, as they heard a live of ranger six as it a

he made a suggestion to a guy at caltech which is one of the world's leading bio experts and help me understand the microenvironment is the main character in the chapter on the subject. let me tell you a little bit about the micro biome that is not as an initiator. it is the biosphere of bacteria that lives inside of you largely in the gut, about half of your body cells or bacteria populating most of your gut. remember i mentioned that we are not at war with those bacteria's around us. so far from the immune system side, the bacteria certainly don't want to do any harm for us. we are there hotel, tent, youth hostel, go down the list. we are there home. they want to cooperate with us. a word of caution about the micro done under brian. just like i met, we talked about autoimmunity the micro biome research is maybe the most embryonic research of any field that is going to blow up in the extraordinary. it has the potential to tell us as much as we have ever known about human health. but, when you think of the collection of organisms in your gut, all mixed together, billions of different

she has conducted research at caltech library and at harvard. she is a founder at massachusetts general hospital and m.i.t.. her first book is called cured, the people who defeated hiv. she has been published in the new york times, los angeles times and time magazine. in 2016 she published the work that is the basic of her talk tonight, entitled "rise of the rocket girls: the women who propelled us, from missiles to the moon to mars." that work was a bestseller and was widely praised by critics, including one who described it as immersive, evocative, and superbly written. her narrative should be required reading. another commented that when neil armstrong made his giant leap for mankind, there was womankind in the control room. it is a pleasure to welcome to the university of mary washington nathalia holt. [applause] nathalia: thank you so much. i really appreciate you having me here tonight and i am excited to talk to you about rocket girls. this is a group of pioneers whose careers shaped nasa and really made it what it is today. before i get
