This episode is brought to you by Rupa University, AG1, and Pendulum. Dietary cholesterol from saturated fat is often thought to be the cause of high LDL cholesterol and blocked arteries. But we now know from updated research that it's much more complicated than that. Standard cholesterol testing is outdated because it doesn't check for particle size and particle number, information that is needed to tell what's really going on with your cholesterol. Statins are often prescribed to lower LDL cholesterol, but often do not address the root of the problem and can cause very uncomfortable side effects.In today's episode, I talk with Drs. Elizabeth Boham, Ronald Krauss, and Aseem Malhotra about the true role of cholesterol and what is really behind heart disease.Dr. Elizabeth Boham is a physician and nutritionist who practices Functional Medicine at The UltraWellness Center in Lenox, MA. Through her practice and lecturing she has helped thousands of people achieve their goals of optimum health and wellness. She witnesses the power of nutrition every day in her practice and is committed to training other physicians to utilize nutrition in healing.Dr. Ronald Krauss is a Senior Scientist at Children's Hospital Oakland Research Institute, a Professor of Medicine at UCSF, and an Adjunct Professor of Nutritional Sciences at UC Berkeley. Dr. Krauss's research aims to understand how to best prevent cardiovascular disease through early detection and management of its major risk factors: most notably, elevated levels of blood cholesterol and lipoproteins. He has published more than 450 research articles and reviews on metabolic, genetic, dietary, and drug effects on plasma lipoproteins and the risk of coronary artery disease, with more than 100,000 citations of this work.Dr. Aseem Malhotra is an NHS-trained consultant cardiologist and visiting Professor of Evidence-Based Medicine at the Bahiana School of Medicine and Public Health in Salvador, Brazil.

This episode is brought to you by Rupa Health, BiOptimizers, LMNT, and Cozy Earth.Heart disease is still the number one killer in the world, yet most people don't actually understand what markers put them most at risk. The general consensus is there are two types of cholesterol—the good and the bad—the good is thought to be high-density lipoproteins or HDL, and the bad is low-density lipoproteins or LDL. But we now know from research that it's much more complicated than that—there are actually various sizes and densities of these lipoproteins. Today on The Doctor's Farmacy, I'm excited to talk to one of the leading lipidologists, Dr. Ronald Krauss, all about lipoproteins, what they do in the body, what they mean for heart disease risk, and why a typical lipid panel alone is insufficient.Dr. Krauss is a Senior Scientist at Children's Hospital Oakland Research Institute, a Professor of Medicine at UCSF, and an Adjunct Professor of Nutritional Sciences at UC Berkeley.

Terra Verde host and Earth Island Journal Editor, Maureen Nandini Mitra, talks two award-winning Bay Area eco-poets and authors, who also happen to be scientists — have Sonoma County Poet Laureate Maya Khosla and Lucille Lang Day founder of Scarlet Tanager Books, about eco-poetry and the power of ideas and words, to change minds. Maya Khosla, who is also field-based biologist and a writer and filmmaker and she has just come out with a new book of poems All the Fires of Wind and Light published by 16 Rivers Press,  which invites readers to find themselves in the wild, even in the most challenging times. Lucille Lang Day has worn many hats. Among other things, she's been a science writer and administrator at Lawrence Berkeley National Laboratory and a staff scientist at Children's Hospital Oakland Research Institute. Her publishing house has just come out with a new anthology of poems that she has co-edited — Fire and Rain: Ecopoetry of California. The post Speaking to the Heart – Eco-Poetry and Environmentalism appeared first on KPFA.

Dr Ames is a professor of Biochemistry and Molecular Biology Emeritus at the University of California, Berkeley, and a senior scientist at Children's Hospital Oakland Research Institute. His research has been fundamental in developing our understanding of how suboptimal micronutrient intakes contribute to accelerated aging and chronic diseases such as cancer, cardiovascular disease, immune dysfunction, and cognitive decline. Recently he expanded his ‘triage theory’ to introduce two concepts inherent in the triage-rationing mechanism: longevity proteins and longevity vitamins. This indicates there is a new class of vitamins that are essential for healthy ageing, but do not have the immediate deficiency-related disease of traditional vitamins. Dr Ames shares his theory and its implications for nutrition, health and personalized medicine.   Further reading:   Ames BN. Prolonging healthy aging: Longevity vitamins and proteins.

Dr. Rhonda Patrick is a scientist who has done extensive research on aging, cancer and nutrition. She has a Ph.D. in biomedical science from the University of Tennessee Health Science center and St. Jude’s children’s research hospital in Memphis Tennessee, a bachelor's of science degree in biochemistry/chemistry from the University of California San Diego and has trained as a Postdoc at the Children’s Hospital Oakland Research Institute with Dr. Bruce Ames. Her research on the role of insulin signaling in protein misfolding commonly found in neurodegenerative diseases, such as Alzheimer's disease, was conducted at the prestigious Salk Institute for biological Sciences. Rhonda's podcast and website, both called Found My Fitness, discuss topics such as the role of micronutrient deficiencies in diseases of aging, the benefits of exposing the body to hormetic stressors such as exercise, fasting, sauna use or various forms of cold exposure, and the importance of mindfulness, stress reduction and sleep on health. In this episode we discuss Rhonda's new publication on the role of the APOE4 gene in Alzheimer's Disease, and why eating fish but not taking fish oil DHA supplements help slow the progression of the disease for carriers. We also touch on how we both approach healthy pregnancies and Rhonda's personal nutrition strategies. For complete show notes visit: http://summertomato.com/category/podcast

Dr. Ronald Krauss Dr. Ronald Krauss, M.D. is the director of atherosclerosis research at Children's Hospital Oakland Research Institute, Adjunct Professor at UCSF and UC Berkeley. Dr. Krauss is really one of the pioneering scientists that changed the way we all think about cholesterol and saturated fat. He developed an assay that allows the quantification of low density lipoprotein particle size and concentration (known to the wider world as LDL cholesterol) based on a technique which determines the size of the particle based on physics...meaning the speed at which it flies through the air. In this episode, Rhonda and Ron discuss what HDL and LDL cholesterol are, what they do in the body and how they play a role in heart disease. We talk about what small, dense LDL particles are, how they form, what effect eating saturated fat versus refined carbohydrates have on LDL particle size and heart disease risk and more generally what the main risk factors for heart disease are. Ron also talks about the good, bad and the ugly of LDL-lowering drugs known as statins and much more.

Bruce Ames Sr Scientist at CHORI, and Prof Emeritus of Biochem and Molecular Bio, at UC Berkeley. Rhonda Patrick Ph.D. biomedical science, postdoc at CHORI in Dr. Ames lab. The effects of micronutrients on metabolism, inflammation, DNA damage, and aging.TranscriptSpeaker 1: Spectrum's next. Speaker 2: Okay. [inaudible] [inaudible]. Speaker 1: Welcome to spectrum the science and technology show [00:00:30] on k a l x Berkeley, a biweekly 30 minute program bringing you interviews featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 3: Hi there. My name is Renee Rao and I'll be hosting today's show this week on spectrum. We present part two of our two interviews with Bruce Ames and Rhonda Patrick. Dr Ames is a senior scientist at Children's Hospital, Oakland Research Institute, director of their [00:01:00] nutrition and metabolism center and a professor emeritus of biochemistry and molecular biology at the University of California Berkeley. Rhonda Patrick has a phd in biomedical science. Dr. Patrick is currently a postdoctoral fellow at Children's Hospital, Oakland Research Institute and Dr Ames lab. She currently conducts clinical trials looking at the effects of nutrients on metabolism, inflammation, DNA damage and aging. In February of 2014 she published [00:01:30] a paper in the Federation of American Societies for Experimental Biology Journal on how vitamin D regulates serotonin synthesis and how this relates to autism. In part one Bruce and Rondo described his triage theory for micronutrients in humans and their importance in health and aging. In part two they discussed public health risk factors, research funding models, and the future work they wish to do. Here is part two of Brad Swift's interview with Dr Ames [00:02:00] and Patrick. Speaker 4: Is there a discussion going on in public health community about this sort of important that Rhonda, that one, Speaker 5: I think that people are becoming more aware of the importance of micronutrient deficiencies in the u s population. We've got now these national health and examination surveys that people are doing, examining the levels of these essential vitamins and minerals. 70% of the populations not getting enough vitamin D, 45% [00:02:30] population is not getting enough magnesium, 60% not getting enough vitamin K, 25% is not getting enough vitamin CS, 60% not getting enough vitamin E and on and on, 90% not getting enough calcium testing. It's very difficult to get. So I think that with these surveys that are really coming out with these striking numbers on these micronutrient deficiencies in the population, I'm in the really widespread and with triage, the numbers that tell you may be wrong because the thinking short term instead of long term, really what you want to know Speaker 6: [00:03:00] is what level [inaudible] indeed to keep a maximum lifespan. And our paper discussed all at and uh, but I must say the nutrition community hasn't embraced it yet, but they will because we're showing it's true and we may need even more of certain things. But again, you don't want to overdo it. Okay. Speaker 4: So talk a little bit about risk factors in general. In health, a lot of people, as you were saying, are very obsessed with chemicals or so maybe their risk assessment is [00:03:30] misdirected. What do you think are the big health issues, the big health risks? Speaker 6: I think obesity is like smoking. Smoking is eight or 10 years off your life. Each cigarette takes 10 minutes off your life. I mean, it's a disaster and smoking levels are going down and down because people understand. Finally, there's still a lot of people smoke, but obesity is just as bad years of expensive diabetes and the costs can be used. [00:04:00] Whatever you look at out timers of brain dysfunction of all sites is higher in the obese and there's been several studies of the Diet of the obese and it's horrible. I mean it's sugar, it's comfort food and they're not eating fruits and vegetables and the not eating berries and nuts and not eating fish. And so it's doing the main and the country is painful. Speaker 5: I think that the biggest risk in becoming unhealthy and increasing your [00:04:30] risk of age related diseases, inflammatory diseases comes down to micronutrient intake and people are not getting enough of that. And we know that we quantified it, we know they're not getting enough. And so I think that people like to focus on a lot of what not eat, don't eat sugar and that's right. You shouldn't eat a lot of sugar. I mean there's a lot of bad effects on, you know, constantly having insulin signaling activated. You can become insulin resistant in type two diabetic and these things are important. But I think you also need to realize you need to focus on what you're not getting as opposed to only focusing on what you should not [00:05:00] be getting. Yeah, Speaker 6: a colleague, lowest scold, and I wrote over a hundred papers trying to put risk in perspective. That part to been in pesticide is really uninteresting. Organic food and regular food doesn't matter. It's makes you feel good, but you're really not either improving the environment or helping your health. Now that you're not allowed to say that, things like that in Berkeley. But anyway, it's your diet. You should be worried about getting a good balanced time. So if you put out a thousand [00:05:30] hypothetical risks, you're lost space. Nobody knows what's important anymore and that's where we're getting. Don't smoke and eat a good diet. You're way ahead of the game and exercise and exercise. Right.Speaker 4: And in talking about the current situation with funding, when you think back Bruce, in the early days of your career and the opportunities that were there for getting funding vastly Speaker 6: different. [00:06:00] Well, there was much less money in the system, but I always was able to get funded my whole career and I've always done reasonably well. But now it's a little discouraging when I think I have big ideas that are gonna really cut health care costs and we have big ideas on obesity and I just can't get any of this funded [inaudible] but now if you're an all original, it's hopeless putting it at grant, [00:06:30] I just have given up on it. Speaker 5: Well the ANA, the NIH doesn't like to fund. Speaker 6: Yeah. If you're thinking differently than everybody else you do and they're only funding eight or 9% of grants, you just can't get funded. I didn't want to work on a 1% so I'm funding it out of my own pocket with, I made some money from a biotech company of one my students and that's what's supporting my lamb and few rich people who saw potential gave me some money. But it's really tough [00:07:00] now getting enough money to do this. That's an interesting model. Self funding. Well, Rhonda is trying to do that with a, she has a blog and people supporting her in, Speaker 5: I'm trying to do some crowdfunding where instead of going to the government and then all these national institute of cancer, aging, whatever, which essentially uses taxpayer dollar anyways to fund research. I'm just going to the people, that's what I'm trying to do. My ultimate goal is to go to the people, tell them about this research I'm doing and [00:07:30] my ideas how we're going to do it and have them fund it. People are willing to give money to make advances in science. They just need to know about it. What did you tell him what your app is? So, so I have an app called found my fitness, which is the name of my platform where I basically break down science and nutrition and fitness to people and I explained to them mechanisms. I explained to them context, you know, because it's really hard to keep up with all these press releases and you're bombarded with and some of them are accurate and some aren't and most of the time you just have no idea what is going on. Speaker 5: It's very [00:08:00] difficult to sort of navigate through all that mess. So I have developed a platform called found my fitness where I'm trying to basically educate people by explaining and breaking down the science behind a lot of these different types of website. And it's an app, it's a website that's also an app can download on your iPhone called found my fitness. And I have short videos, youtube videos that I do where I talk about particular science topics or health nutrition topics. I also have a podcast where I talk about them. I'm interviewing other scientists in the field and things like that. And also I've got a news community site [00:08:30] where people can interact posts, new news, science stories or nutrition stories, whatever it is and people comment. So we're kind of building in community where people can interact and ask questions and Speaker 6: Rhonda makes a video every once in a while and puts it up on her website and she has people supporting at least some of this and she hopes to finally get enough money coming in. We'll support her research. Speaker 5: No, I think we're heading that way. I think that scientists are going to have to findSpeaker 6: new creative ways to fund their research. Uh, particularly if they have creative ideas [00:09:00] is, Bruce mentioned it because it's so competitive to get that less than 10% funding. The NIH doesn't really fun, really creative and risky, but it's, you need somebody who gets it. If when you put out a new idea, right, and if it's against conventional wisdom, which I'd like to do with the occasion arises, then it's almost impossible anyway. Speaker 4: Even with your reputation. Speaker 6: Yeah, it's hard. I've just given [00:09:30] up writing grants now. It's a huge amount of work and when they keep on getting turned down, even though I think these are wonderful ideas, luckily I can keep a basal level supporting the lab. I found a rich fellow who had an autistic grandkid guy named Jorgensen and he supported Rhonda and he supported her for a year and she was able to do all these things. Yeah, my age, I want to have [00:10:00] a lot of big ideas and I just like to get them out there anyway. We shouldn't complain. We're doing okay. Right. It's a very fulfilling job. There's nothing more fulfilling than doing science in my opinion. Yes. Speaker 7: You're listening to spectrum and k a Alex Berkley. Today's guests are Dr. Bruce Ames and Dr Rhonda Patrick of Children's Hospital Oakland Research Institute. [00:10:30] Oh, Speaker 4: the ames test. When you came up with that, was that, what was the process involved with?Speaker 6: Well, how do you devise that? Well, I was always half a geneticist and half a bio chemist and I thought you Taishan is really important. And nobody was testing new substances out there to see if there were mutagens. And so I thought it'd be nice to develop a simple, easy test in bacteria for doing that. That [00:11:00] was cheap and quick. And then I became interested in the relation of carcinogens to mutagens and so I was trying to convince people at the active forms of carcinogens were muted. There were other people in that area too, but I was an early enthusiastic for that idea and anyway, it's just came from my knowledge of two different fields, but that's a long time ago. I'm more excited about the brain now. The current stuff Speaker 4: doing obviously is it's more [00:11:30] exciting. Yeah. Do you both spend time paying attention to other areas of science? Speaker 6: I read an enormous amount and every 10 or 15 years I seem to change my feel of and follow off something that seems a little hotter than the other things and I've been reasonably successful at that, so that's what I liked to do. I am constantly Speaker 5: about all the latest research coming out. I mean, that's like pretty much all I do is I'm very excited about the new [00:12:00] field of epigenetics, where we're connecting what we eat, our lifestyle, how much stress we are under, how much exercise we do, how much sleep we get, how this is actually changing, methylation patterns, acetylation patterns. In our DNA and how that can change gene expression, turn on genes, turn off genes. I mean how this all relates to the way we age, how it relates to behavior, how it relates to us passing on behaviors to our children, grandchildren, you know, this is a field that's to me really exciting and something that I've spend quite a bit of time reading about. So for both of [00:12:30] you, what have been in the course of your career, the technologies, Speaker 6: the discoveries that have impacted your work the most? Well obviously understanding DNA and all the things it does was a huge advance for biology. And I was always half a geneticist, so I was hopping up and down when that Watson Crick paper came out and I gave it in the Journal club to all these distinguished biochemists and they said very speculative. [00:13:00] I said I was young script. I said, you guys be quiet. This is the paper of the century. And it made a huge difference. And there's been one advance after another. A lot of technical advances, little companies spring up, making your life easier and all of that. So it's been fun going through this. Speaker 5: I think, you know, in terms of my own research, which got me to where I'm at now, a lot of the, the technological advances in making transgenic mouse models, [00:13:30] knocking out certain genes, being able to manipulate, doing, inserting viral vectors with a specific gene and with a certain promoter on it and targeting it to a certain tissue so you can, you know, look specifically at what it's doing in that tissue or knock it out and what it's doing and that tissue. That for me is a, been a very useful technology that's helped me learn a lot. In addition, I like to do a lot of imaging. So these fluorescent proteins that we can, you know, you use to tag on, look at other proteins where they're located both tissue wise and also intracellularly inside the cell. Doing [00:14:00] that in real time. So there's now live cell imaging we can do and see things dynamically. Like for example, looking at Mitochondria and how they move and what they're doing in real time. Like that for me is also been really a useful technology and helping me understand Mitochondria. And how they function, dysfunction can occur. So I think a, those, those have been really important technologies for me. Speaker 6: And then computers change biology. Google made a huge difference. You can put two odd facts into Google and outcome Molly's paper. You'd spend years in a library [00:14:30] trying to figure all this stuff out. So Google really made theoretical biology possible. And I think this whole paper that Rhonda did, she couldn't have done it without Google. That's was the technology that opened it all up. This is so much literature and nobody can read all this and remember it all that we need the search. And so is this kind of a boom in theoretical biology? Well, [00:15:00] I wouldn't say there's a boom yet, but there's so much information out there that people haven't put together. Speaker 5: Yeah, people have been generating data over the years. There's tons of data out there and there's a lot of well done research that people haven't put together, connected the dots and made big picture understanding of complex things. So I think that there is an opening for that. And I do think that people will start to do that more and they are starting to do it more and more. Speaker 6: So in the past there really wasn't a theoretical biology that was certainly Darwin was [00:15:30] theoretical you could say and lots of people had big ideas in the unified fields, but it was rare. Speaker 5: I think we have more of an advantage in that we can provide mechanisms a little easier because we can read all this data. You know people like Darwin, they were doing theoretical work but they were also making observations. So what we're doing now is we're looking at observations other people have made and putting those together. Speaker 8: [00:16:00] [inaudible] and [inaudible] is a public affairs show on k a l x Berkeley. This is part two of a two part interview with Bruce Ames and Rhonda Patrick. Speaker 6: Are there, are other scientists active in the longevity field whose work you admire that you would love to collaborate with? [00:16:30] Well or associated with? Always collaborates. So science is both very collegial and very competitive. You think somebody might get their first. But one of the tricks I like in my lab is we have half a dozen really good people with different expertise and we sit around a table and discuss things and it's no one person can know all medicine. And so [00:17:00] anyways, that helps. Yeah. And it might be collaborating with this guy now because both of you contribute something that the other person doesn't have a technique or whatever. And in three years we might be competing with them, but that's why it's good to keep good relations with everybody. But business is the same way companies compete and collaborate. Yeah. Speaker 5: I, I personally am in terms of the field of longevity. Uh, I admire the work of Elizabeth Blackburn [00:17:30] who discovered, uh, won the Nobel prize for be playing a role in discovering the enzyme telomerase Speaker 6: that was done at Berkeley, by the way. Speaker 5: Yeah. And she's now a professor at UCLA. So I would be really excited to set up a collaboration with her. Speaker 6: Well, what are the lab's research plans going forward now? Uh, well, other than Ryan Reinders next two papers. Yeah. Rhonda has these papers to get out. And I'd like to get the whole business [00:18:00] of tuning up our metabolism on firmer ground, convince nutrition people who are expert in one particular environment or most people studied B six for their whole lives or study Niacin for their whole lives or magnesium. And I buy it at the experts in a particular field to think about triage and what protein do we measure that tells you you're short a not getting enough, the vulnerable ones and get that idea [00:18:30] out and do a few examples and convince people that RDA should be based on long term effects rather than short term. And then Rhonda and I were talking the other day and we both got excited about drugs. This money to be made. Speaker 6: So pharmaceutical companies compete on getting new and better drugs and they can be billion dollar drugs but nutrition, nobody can make money out of it. And so there, [00:19:00] do you want to do a clinical trial on Vitamin d the way you do with the drug? Food and drug wants a double blind randomized controlled clinical trial. That's the gold standard for drugs. But it's not for nutrition is nutrition. You have to measure if 20% of the population is low on vitamin D, you don't want to do a study where you don't measure who's low and who's high because otherwise it's designed to fail. So you have to measure [00:19:30] things. Now, vitamin D actually many more deficient, but a lot of vitamins, 10% of lower 20% is low and you can't just lump them in with all the people have enough and do a randomized on one clinical trial and think it's going to mean something without measuring something. Speaker 6: Rhonda has one of her videos on our website to [inaudible] all these doctors who saved the vitamins are useless. They're all based on clinical trials that are designed for drugs [00:20:00] and they don't measure anything. So you have to know who should deficient and then taking that amount of value and makes you sufficient. I think, uh, some interesting re ongoing research in our lab is also the cornea bar. Yeah. So yeah, Joyce mechanical amp is directing a project on the Corey bar. We were deciding how do you get vitamins and minerals into the poor and we made a little bar, which is kind of all the components of a Mediterranean diet that people [00:20:30] aren't getting enough vitamins and all the vitamins and minerals and fish oil and vitamin D and soluble fiber and insoluble fiber and plant polyphenols and we can raise everybody's HDL in a couple of weeks and this is the mass of people aren't eating, they think they're eating good tide aren't and obese people or have their metabolism all fouled up and you were even learning how to make progress there. So Speaker 5: cool thing about it is that you can take a population [00:21:00] of people that eats very unhealthy and they are obese, meaning they have a BMI of 30 or above and you can give them this nutritional bar that has a variety of micronutrients. It has essential fatty acids and some polyphenols fiber and give it to them twice a day on top of their crappy diet. You don't tell them to change your diet at all. It's like keep doing what you're doing, but here, eat those twice a day on top of what you're doing and you can see that, you know after a few weeks that these changes start to occur where their HDLs raise or LDS lower. I mean there's, there's a lot of positive effects, you know, lower c reactive protein. So [00:21:30] I think this is really groundbreaking research because it's, it says, look, you can take someone who's eating a terrible diet completely, probably micronutrient division in many essential vitamins and minerals and such are eating a bunch of sugar and crap and processed foods and on and on and on and yet you can give them this nutritional bar that has a combination of micronutrients in it and you can quantify changes that are positive. Speaker 5: I think that's a really exciting ongoing project in our lab, Speaker 6: Bruce Ames and Rhonda Patrick, thanks very much [00:22:00] for being on spectrum. It's a pleasure.

On Saturday, July 19th you see Berkeley molecular and cell biology Professor Kathleen Collins will host the latest iteration of the monthly lecture series. Signs that cow Professor Collins will discuss the connections between the seemingly incontrovertible fact of human aging. A fascinating enzyme known as telomerase and malignant cancers. Speaker 3: While cancer cells can grow indefinitely [00:25:00] all normally functioning human tissues will eventually die out. This is because with each success of cell division, the protective cap or a telomere at the end of each chromosome is gradually degraded while the enzyme to limb arrays or pairs this damage in embryos. It is not fully active in adult human tissues. Perhaps to prevent the uncontrollable growth of cancer cells. Professor Collins will discuss telomeres and telomerase function and how they affect the balance of human aging [00:25:30] and immortality. The free public talk will be held July 19th in room one 59 of Mulford Hall on the UC Berkeley campus. The lecture will begin at 11:00 AM sharp science need is a monthly science happy hour for adults 21 and over the pairs. Lightning talks with interactive stations on the back patio of the El Rio bar at three one five eight mission street in San Francisco. Speaker 3: [00:26:00] The theme for July Science Neat is backyard science and we'll feature the science of things right here in the bay area from plants to plankton and beetles. Two bikes. Admission is $4 and the event will be on Tuesday, July 22nd from six 30 to 8:30 PM and now a few of our favorite science stories. Rick's back to present the news. The rocky planets that are closest to our son generally have an iron core [00:26:30] that makes up about a third of their mass that is surrounded by rock that makes up the other two thirds. Mercury is an exception and is the other way around. With a massive iron core that takes up about percent of the planet's mass. This has been difficult to explain. If mercury had been built up by collisions the way that Venus and earth and Mars where we'd expect it to have a similar composition in a letter published in nature geoscience on July six Eric s [00:27:00] fog and Andreas Roofer of Arizona State University report their simulations that suggests that collisions may have stripped away Mercury's mantle, some moon and planet sized rocks would bounce off of each other, sometimes knocking one body out of its orbit while the impactor and the leftover debris coalesced into a planet. Speaker 3: This model is consistent with Mercury's high abundance of [inaudible] elements that have been observed recently by NASA's messenger spacecraft [00:27:30] in their so called hit and run model. Mercury is missing metal would end up coalescing onto Venus or in your report compiled by UC Berkeley. Scientist has definitively linkedin gene that has helped Tibetan populations thrive in high altitude environments to hit or too little known human ancestor. The Denisovans, the Denisovans along with any thoughts when extinct around 40 to 50,000 years ago about the time that modern human began to ascend [00:28:00] and Aaliyah is a version of a gene in this case and unusually of the gene e p a s one which regulates hemoglobin production has been common among Tibetans since their move several thousand years ago. John Habit areas at around 15,000 feet of elevation. Well, most people have Leos that caused them to develop thick blood at these high elevations, which can later lead to cardiovascular problems. The tobacco wheel raises hemoglobin levels only slightly allowing possessors [00:28:30] to avoid negative side effects. So the report, which will later republished in the journal Nature details the unique presence of the advantageous aliyah. Among Tibetans and conclusively matches it with the genome of the Denisovans. This is significant because as principle author, Rasmus Nielsen, UC Berkeley professor of integrative biology writes, it shows very clearly and directly that humans evolved and adapted to new environments by getting their genes from another species. Nielsen added that there are many other [00:29:00] potential species to explore as sources of human DNA Speaker 8: [inaudible].Speaker 4: This show marks the end of our production of spectrum.

Rhonda Patrick has a phd in biomedical science. Dr. Patrick is currently a postdoctoral fellow at Children's Hospital, Oakland Research Institute in Dr Ames. His lab, she currently conducts clinical trials looking at the effects of [00:01:30] micronutrients on metabolism, inflammation, DNA damage and aging. Here's Brad swift and interviewing doctors, aims and Patrick Bruce Speaker 5: Ames and Rhonda Patrick, welcome to spectrum. Thank you very much. Sue, can you help us understand the term micronutrient and briefly explain what they do? Sure. Speaker 6: About 40 substances you need in your diet and [00:02:00] you get it from eating a really well balanced style, get them more about eight or 10 of them are essential amino acids. So they're required for making your all your protein. And then there are about 30 vitamins and minerals, roughly 15 minerals in 15 five minutes. So you need the minerals, you need iron and zinc and calcium and magnesium and all these things, you know, and the vitamins [00:02:30] and minerals are coenzymes. So you have 20,000 genes in your body that make proteins, which are enzymes that do bio or Kimiko transformations. And some of them require coenzymes, maybe a quarter of them. So some require magnesium and they don't work unless there's a magnesium attached to the particular pace in the enzyme. And some of them require vitamin B six which is something called [00:03:00] paradoxal, goes through a coenzyme paradox of phosphate. Speaker 6: And that's an a few hundred and enzymes and they make your neurotransmitters and other things. And if you don't get any one of these 40 substances, you'd die. But how much we need is, I think there's a lot of guesswork in there and we have a new idea I can talk about later that shakes a lot up puppet. And so when your research, you're trying to measure these [00:03:30] micronutrients obviously, well people can measure them in various ways. Somebody can just measure in blood and say, ah, you have enough vitamin D or you don't have enough vitamin D. But some, for example, calcium and magnesium marine, your bones, but they're also used for all kinds of enzymes and if you get low, the tissue might get low, but you keep your plasma up because you're taking it out of the bone. So just measuring [00:04:00] plasma isn't useful in that case. Speaker 6: But anyway, there, uh, each one is a little different. Do you want to talk about the triage theory? Okay, I could talk to about that. Now. Some years ago we kept on finding when we had human cells in culture or mice, that when we left out various vitamins and minerals or didn't have enough, we got DNA damage. I'm an expert in DNA damage and we're interested in how [00:04:30] to prevent DNA damage. We sat leads to cancer and so I kept on wondering why is nature doing this when you're not getting enough of magnesium or iron or zinc, you getting DNA damage and then one day it hit me. I, that's just what nature wants to do. Through all of evolution, we'd been running out of vitamins and minerals. The minerals aren't spread evenly through the soil. The red soils with a lot of iron and the souls that have very little iron. Speaker 6: [00:05:00] Selenium is a required mineral, but there's soils with too much saline and we get poisoned. And then the areas where it, you don't have enough selenium so you get poisoned. So it's a little tricky. Back in 2006 I had this idea that nature must do a rationing when you start getting low on any vitamin or mineral, and how would you ration it? The proteins that are essential for survival get it first and the ones that are preventing [00:05:30] some insidious damage that shows up as cancer in 10 years or calcification in the arteries. That's the [inaudible] papers, those proteins lucid. And I call this triage ship. It's a French word for dividing up those wounded soldiers that the doctors can make a difference on. So anyway, I publish this with what data? That wasn't the literature, but it wasn't completely satisfactory. We didn't, hadn't really nailed it, but it was an idea. Speaker 6: And then Joyce McCain [00:06:00] in my lab wrote two beautiful reviews, one on selenium and one on vitaminK , and they both fit beautifully. And people who work in these fields had shown that the clotting factors get it first because you don't get your blood clotting and you cut yourself every week or two, you'd just bleed to death. But the price you pay is you don't make the protein that prevents calcification of the arteries so [00:06:30] people can die of calcification the arteries. But that takes 10 years. So when nature has to face keeping alive now so you can reproduce or you're getting calcification arteries in 10 years, it does this tradeoff. And also you don't have enough vitamin K. My ptosis doesn't work quite as accurately. So you'll lose the chromosome here or there and you get cancer in 10 years. But again, it's the trade off between short term survival and longterm health. Speaker 6: It all [00:07:00] makes perfect sense. It was a very plausible theory. That's why I came out with it. But it's true for vitaminK and the mechanism used in vitaminK is different than the mechanism and sleeping. So each system has developed a different mechanism for doing this racially. And so that changes our view of vitamins and minerals base. You're paying a price every time. You're a little low on one with them. So it's the disease of aging. So basically when you should have any vitamin or mineral, [00:07:30] it accelerates your aging in some way. You can accelerate some kind of insidious damage. And we're talking about huge numbers of people. 70% of the population is low in vitamin D and we're talking about magnesium, what we said the third 45% 45% these are big numbers and they're cheap boldly saying Speaker 7: [inaudible]Speaker 8: [00:08:00] you are listening to spectrum on a l x, Berkeley. Today's guests are Dr. Bruce Ames and Dr Rhonda Patrick Speaker 9: with the micronutrients and the activity of DNA, RNA. Talk about the effect there, the impact, is there more to talk about that? Absolutely. So there are many different micronutrients [00:08:30] that are required for functions in your body that involve DNA replication involved DNA repair, preventing DNA damage. Things are all very important because we're making 100 billion new cells every day to make a new cell, we have to replicate the entire genome of that cell to make the daughter cell. And that requires a whole holster of enzymes. So if you don't have enough magnesium for those DNA polymerase to work properly, when ends up happening is that their fidelity is [00:09:00] lessen, meaning they don't work as well and they're gonna likely make more errors in that DNA replication that they're performing. And if they can't repair that error, then when ends up happening is that you can get every rotation and depending on whether that mutation has any functional consequences, sort of random, but the more times as occurs, then the more chances you're having of getting a mutation that can, you know, something that's not good and can either cause cell death or it can also [00:09:30] be something that causes dysregulation of the way your genes are expressed. Speaker 9: So it's very important to make sure you have the right co factors such as magnesium for DNA replication, also in your mitochondria and your mitochondrial DNA. When you make new Mitochondria, this is called mitochondrial biogenesis. It's an important mechanism to boost the number of mitochondria per cell. And this can occur during things like exercise when your mitochondria also have their own genome and they have to replicate this genome. Well guess what? Those mitochondrial [00:10:00] DNA were preliminaries. This also require magnesium. And so if there's not enough magnesium around, you're not making your mitochondria as optimal as you could be in Mitochondria. Play an important role in every single process in your body, including, you know, neuronal function. So that's really important to make sure that your Mitochondria Hobby. Also, this is very relevant for things like aging. These micronutrients like vitamin D gets converted into a steroid hormone that regulates the expression of over a thousand genes in [00:10:30] your body and some of those genes are involved in DNA repair and also in preventing DNA damage. So these micronutrients are extremely important for a variety of different physiological properties that are going on in your body every single day. Things that you can't see when you look in the mirror, we're talking about something that's not an acute deficiency that's going to lead to a clinical symptom like scurvy. Speaker 6: We think bad nutrition is the main thing, accelerating all these degenerative diseases of aging and contributing to these huge medical costs and [00:11:00] all of that. And it's something you can do something about because they're all very cheap minerals that are cheap. So the sourcing of the minerals and vitamins, it's not crucial at this point you think? I don't think so. Yeah. Getting them is the the really the key factor think and I think to really reform people's diet, we're going to need the numbers and we're working to try and show that there's some vulnerable protein that goes first when you're short of McNeese. I [00:11:30] mean you should measure that and then you'll know you're not getting enough and all the consequences or you're disabling all your DNA repair fronts. I'm so whatever. Speaker 9: It is ideal to try and get as many of these micronutrients essential vitamins and minerals that you can from your diet. For example, I personally make a smoothie for breakfast every morning, which consists of Kale, spinach, Swiss carrots, tomato, avocado, berries, and I'm getting a broad spectrum of vegetables and fruits [00:12:00] just from that one smoothie. And I think in addition to these essential vitamins and minerals that we know are in these various plants and fruits, I think there's also a lot of micronutrients in there that we have yet to discover that also may be doing important things. However, it's extremely difficult for people to get all of these micronutrients from their diet. And I think in that instance, supplementation can help fill those nutritional gaps. And we've actually shown that Speaker 6: in general, people in nutrition don't like the idea of pills, but people [00:12:30] are learning about all this. But you shouldn't overdo it. Mae West said too much of a good thing is wonderful, but she was saying about sex, not micronutrients, and particularly for minerals in minerals, there's a sweet spot. Too much can hurt you into little canary, Speaker 5: and that's what you're hoping these next generation devices would help people understand where they are situated within, right? The class of vitamins and minerals. What are they up in? What are they down? Speaker 6: So this may be a decades [00:13:00] worth of science to do this, but we're trying to frame the ideas and say, look, this is where we're going. And it isn't drugs that are gonna help you. It's getting your diet tuned up, your metabolism [inaudible] Speaker 9: your doctor can look at a few different nutrients and vitamin D is one test that they do. But there's a couple of companies that are out there right now such as something called wellness effects. They're measuring a variety of different micronutrients in people's blood, including omega [00:13:30] three fatty acids, vitamin D, magnesium, potassium, calcium. So looking at all these different vitamins and minerals and people are quantifying. It's called the quantified self movement where people are getting their vitamins and minerals and essential fatty acids measured. They're making dietary changes. If they find out they're low in vitamin D or they're low in mega three or they have low magnesium, they're making dietary changes and then about three months later they go back and they'd quantify the levels again so they can physically measure and quantify this, this change that they're making in their diet. And I think really that's the direction [00:14:00] to go. Speaker 6: Yeah, and analytical methods of Guinea. So wonderful that you can do it on a finger prick of blood. I have two entrepreneurs, scientist friends. One of them has put a machine in every hospital in China and he measures couple of dozen proteins of medical importance and the Chinese are subsidizing this. They think it's going to save money. And another friend of mine from Boulder, first one is built routed. The second one is Larry Gold. And he developed [00:14:30] an alternative to monoclonal antibodies and he can measure 1500 different proteins in one fingerprint compliant. I mean, it's fantastic and he's working to get them all right now it's a discovery system, but we're going to discover what protein tells you. You're low in magnesium and what protein tells you you're low in vitaminK or protein tells you low in paradox and then it's all going to go to your iPhone and you'll get the diagnosis. Speaker 6: We'll cut out the doctors [00:15:00] because they don't know much about Olis anyway, and they're too expensive. So it's not drugs you need for all of this. It's tuning up limit tap of the drugs that youthful. I'm not saying that not and for some things that are absolutely essential, but this area of getting your metabolism tuned up, see, people are worried about a pot Papillion a pesticide and it's all irrelevant. We, we published a hundred papers on that in that era, just saying, look, it's all a distraction from the important thing and important thing [00:15:30] is all these bad diets where eating and obesity isn't just calories in, exercise out a beach. People are starving and what this starving for vitamins and minerals because they're eating sugar and carbohydrate and every possible disease of aging is accelerated and hippies and plus huge costs, years of expensive diabetes and heart disease and cancer, you name it, it's been linked to obesity. So I think it's a big [00:16:00] opportunity to tune people up. Speaker 8: Spectrum is a public affairs show on k a l x Berkeley [00:16:30] is this part one of a two part interview with Bruce Ames and Rhonda Patrick. Speaker 9: So Rhonda, the recent paper you published on vitamin D explain that. So vitamin D gets converted into a steroid hormone in your body and the steroid hormone can regulate this expression [00:17:00] of between 900 and a thousand different genes. And the way it does that is that there's a little telltale sequence in your gene and it's basically a six nucleotide sequence repeat that's separated by three nucleotides. And this nucleotide sequence itself can determine whether or not vitamin D will turn on a gene or turn off aging. And so vitamin D can do both of these where it turns on genes and turns off genes. Well, what we found is that there's two different genes that encode for Tryptophan hydroxylase, [00:17:30] which is the rate limiting enzyme that converts trip to fan into Serotonin. There's one that's in the brain called Tryptophan hydroxylase too, and there's one that's outside of the blood brain barrier in tissues like Mosley got also in your t cells and your Peniel gland and placenta tissue if you're woman, and this is called Tryptophan hydroxylase one and what we found is that both of these genes have what's called a vitamin D response element that tell a sequence I was telling you about. Speaker 9: However, they had [00:18:00] completely opposite vitamin D response elements. One, the one in your brain had an activation sequence turn on and the one in the gut had a repression sequence. The turnoff sequence, which suggested that vitamin D hormone was controlling the expression of these two different genes in opposite directions. Vitamin D's important to turn on Tryptophan hydroxylase and two and your brain so you can make serotonin and it's important to turn it off and your gut to blunt the production of Serotonin in your gut. Serotonin in your gut. Too Much of it causes GI inflammation. [00:18:30] This was a really cool finding because there was a recent paper where they found that autistic individuals, 90% of them had some abnormal tryptophan metabolism and they didn't really identify what it was, but sort of like an Aha moment where it was like trick to fan metabolism. Well, chuck did fan, you need to make Serotonin, and so I started doing some reading and sure enough, there's a whole literature connecting Serotonin to autism. Speaker 9: Serotonin is made in your brain. It's an important neurotransmitter, but during early, early brain development, [00:19:00] it is a brain morphogenic meaning it actually is a growth factor that guides the neuronal proliferation, the development, the migration of neurons to different regions in the brain. It plays an essential role in shaping the structure and the wiring of the early developing brain. And so not having enough serotonin in early, early brain development in Utero can lead to very aberrant brain morphological and functional consequences. You know, this was kind of like, wow, well what if you're not getting enough vitamin D during that critical [00:19:30] period, which is important to activate that gene that converts Tryptophan into Serotonin? Is it possible then that you wouldn't be making enough serotonin in that early brain and therefore you wouldn't have a normal brain development? Also, the Serotonin in the gut can cause a lot of GI inflammation and also quite a few autistics have high GI inflammation. Speaker 9: Also, they have high levels of Serotonin in their blood. There's something that we call the Serotonin anomaly where they've measured brain levels of Serotonin autistics from SMRI and have also measured blood levels [00:20:00] of Serotonin. And there was sort of this weird dichotomy where autistics had high levels of Serotonin in their blood, but they had low levels in their brain and so it was like, well, why is that? Why would they have high levels in their blood, the low levels in the brain and we think we found a mechanism why if you're low in vitamin D, your vitamin D won't be turning on the one in your brain and you won't be making enough Serotonin in your brain and it won't be repressing the one you've got and you'll be making too much and you've got this sort of a a really cool finding. We also in our paper discuss how estrogen can [00:20:30] activate Tryptofan hydroxylase to in the brain pretty much the same way vitamin D does also a steroid hormone and the sequences, the receptors bind to a somewhat similar under dug out of the literature that people showed. Estrogen can turn Speaker 6: on the Messenger RNA for the brain enzyme making serotonin in girls, but it's not doing it in boys, which explains why five times as many boys get autism as girls. [00:21:00] Anyway, she worked out all this mechanism. We kept on explaining one thing after another render would come in every week, hopping up and down. Look what I found and look what I found and I think she walks on water, but she did this wonderful scholarship, which is a good metaphor, but she used to be a surfing instructor when she was incentive. Speaker 9: It's pretty exciting. It was largely theoretical work where we did find a underlying mechanism to connect these dots. So we're hoping now that people in the field are going to continue on and look even deeper. Speaker 6: So [00:21:30] what we think we know is how to prevent autism. But what we are not sure of is whether you can give vitamin D to people who have autism and help some of the symptoms. Uh, biggest people need to do clinical trials on all of this and they haven't done them right. But now that we have the mechanism, you can do them right. The trouble is drug companies aren't going to make money with vitamin D and they know that. And so [00:22:00] they're trying to develop a new drug. But we're hoping that these biochemicals trip to fain and vitamin D and nowhere to tone and and may get threes, which are all seem to be involved, which you can find out by reading Ramdas paper that that is going to at least give him mechanisms so we can do more focused clinical trials. Speaker 8: [inaudible] [00:22:30] to learn more about the work and Patrick are doing visit their websites, Bruce ames.org and found my fitness.com Speaker 7: oh Speaker 6: papers take a lot of polishing. Basically we're going into all these fields [00:23:00] that we don't know an awful lot about us and that requires a lot of double checking and sending it to experts and getting criticism. Speaker 9: First you have to learn everything and then you'd have to put, make the connections together and then you have to write it and then there's a whole process. It's very, it's a lot of work. Personally, my favorite part of it is the creative part where you just make all the connections and you find things and you start fitting things together and it's like, oh yeah, you know, it's just, it's almost like awesome rush, but then once you've make all those connections and you do that creative work, then you really have to [00:23:30] do all the tedious, hard digging and working diligence. Yes and that it's not as much fun. Then once you have a good theory Speaker 6: you assume no. Is it explaining new things that you didn't expect and right away this idea explains so many things and it was all really lying on the ground and round it just picked it up and put it together. Speaker 9: People like Bruce and I who liked to make those connections. I think that we play an important role in science as well. Like this paper that we published recently, [00:24:00] while we didn't physically do any experiments, we didn't test our theoretical work. We made a very interesting connection with a mechanism for other people to test. And I think that every once in awhile science needs that because there's so much data out there and now with Google we have access to all this data. So I think that taking people that are familiar with the fields and can put things together like pieces of a puzzle, I think that also advanced the science in a very creative way. Speaker 6: Biology's so complicated that there hasn't been much room for people [00:24:30] who just sit in their office and do theoretical work. And we do a lot of experimental work in lab and Rhonda is carrying on an experimental problem while she's doing all this. But I like to get it in between fields. I was always half a geneticist and half a biochemist and it was wonderful because I saw all these problems. The geneticists turned up and the biochemists didn't know existed and the geneticists didn't know how to tackle this was before Watson and crick and all of that. Uh, I'm pretty [00:25:00] old anyway. I think science is so competitive, but if you know two fields in this an interface, you have a big advantage on everybody else and we like to have people in the lab with many different expertise and put things together.

Speaker 4: The research team created a circular runway with four spokes and feeding machines at the end of each spoke that contained different flavors of food pellets. The feeding was preceded by a tone that indicated how long the rat would wait at a particular machine for food if the rat left one of these restaurants with waiting time below [00:27:30] its threshold only. Do you find an even longer waiting time at the next spoke? The team hypothesized that the rat may regret the choice. Indeed, the rats that fit this description were more likely than control rats to look toward the spoke. They just left and electrodes indicated that neurons in the orbital frontal cortex fired at the same time. Science news talk to cold Spring Harbor Neuro scientist Alex Vaughan about the paper.

Dr Ames is a senior scientist at Children's Hospital, [00:01:00] Oakland Research Institute, director of their nutrition and metabolism center and a professor Ameritas of biochemistry and molecular biology at UC Berkeley. Rhonda Patrick has a phd in biomedical science. Dr. Patrick is currently a postdoctoral fellow at Children's Hospital, Oakland Research Institute in Dr Ames. His lab, she currently conducts clinical trials looking at the effects of [00:01:30] micronutrients on metabolism, inflammation, DNA damage and aging. Here's Brad swift and interviewing doctors, aims and Patrick Bruce Speaker 5: Ames and Rhonda Patrick, welcome to spectrum. Thank you very much. Sue, can you help us understand the term micronutrient and briefly explain what they do? Sure. Speaker 6: About 40 substances you need in your diet and [00:02:00] you get it from eating a really well balanced style, get them more about eight or 10 of them are essential amino acids. So they're required for making your all your protein. And then there are about 30 vitamins and minerals, roughly 15 minerals in 15 five minutes. So you need the minerals, you need iron and zinc and calcium and magnesium and all these things, you know, and the vitamins [00:02:30] and minerals are coenzymes. So you have 20,000 genes in your body that make proteins, which are enzymes that do bio or Kimiko transformations. And some of them require coenzymes, maybe a quarter of them. So some require magnesium and they don't work unless there's a magnesium attached to the particular pace in the enzyme. And some of them require vitamin B six which is something called [00:03:00] paradoxal, goes through a coenzyme paradox of phosphate. Speaker 6: And that's an a few hundred and enzymes and they make your neurotransmitters and other things. And if you don't get any one of these 40 substances, you'd die. But how much we need is, I think there's a lot of guesswork in there and we have a new idea I can talk about later that shakes a lot up puppet. And so when your research, you're trying to measure these [00:03:30] micronutrients obviously, well people can measure them in various ways. Somebody can just measure in blood and say, ah, you have enough vitamin D or you don't have enough vitamin D. But some, for example, calcium and magnesium marine, your bones, but they're also used for all kinds of enzymes and if you get low, the tissue might get low, but you keep your plasma up because you're taking it out of the bone. So just measuring [00:04:00] plasma isn't useful in that case. Speaker 6: But anyway, there, uh, each one is a little different. Do you want to talk about the triage theory? Okay, I could talk to about that. Now. Some years ago we kept on finding when we had human cells in culture or mice, that when we left out various vitamins and minerals or didn't have enough, we got DNA damage. I'm an expert in DNA damage and we're interested in how [00:04:30] to prevent DNA damage. We sat leads to cancer and so I kept on wondering why is nature doing this when you're not getting enough of magnesium or iron or zinc, you getting DNA damage and then one day it hit me. I, that's just what nature wants to do. Through all of evolution, we'd been running out of vitamins and minerals. The minerals aren't spread evenly through the soil. The red soils with a lot of iron and the souls that have very little iron. Speaker 6: [00:05:00] Selenium is a required mineral, but there's soils with too much saline and we get poisoned. And then the areas where it, you don't have enough selenium so you get poisoned. So it's a little tricky. Back in 2006 I had this idea that nature must do a rationing when you start getting low on any vitamin or mineral, and how would you ration it? The proteins that are essential for survival get it first and the ones that are preventing [00:05:30] some insidious damage that shows up as cancer in 10 years or calcification in the arteries. That's the [inaudible] papers, those proteins lucid. And I call this triage ship. It's a French word for dividing up those wounded soldiers that the doctors can make a difference on. So anyway, I publish this with what data? That wasn't the literature, but it wasn't completely satisfactory. We didn't, hadn't really nailed it, but it was an idea. Speaker 6: And then Joyce McCain [00:06:00] in my lab wrote two beautiful reviews, one on selenium and one on vitaminK , and they both fit beautifully. And people who work in these fields had shown that the clotting factors get it first because you don't get your blood clotting and you cut yourself every week or two, you'd just bleed to death. But the price you pay is you don't make the protein that prevents calcification of the arteries so [00:06:30] people can die of calcification the arteries. But that takes 10 years. So when nature has to face keeping alive now so you can reproduce or you're getting calcification arteries in 10 years, it does this tradeoff. And also you don't have enough vitamin K. My ptosis doesn't work quite as accurately. So you'll lose the chromosome here or there and you get cancer in 10 years. But again, it's the trade off between short term survival and longterm health. Speaker 6: It all [00:07:00] makes perfect sense. It was a very plausible theory. That's why I came out with it. But it's true for vitaminK and the mechanism used in vitaminK is different than the mechanism and sleeping. So each system has developed a different mechanism for doing this racially. And so that changes our view of vitamins and minerals base. You're paying a price every time. You're a little low on one with them. So it's the disease of aging. So basically when you should have any vitamin or mineral, [00:07:30] it accelerates your aging in some way. You can accelerate some kind of insidious damage. And we're talking about huge numbers of people. 70% of the population is low in vitamin D and we're talking about magnesium, what we said the third 45% 45% these are big numbers and they're cheap boldly saying Speaker 7: [inaudible]Speaker 8: [00:08:00] you are listening to spectrum on a l x, Berkeley. Today's guests are Dr. Bruce Ames and Dr Rhonda Patrick Speaker 9: with the micronutrients and the activity of DNA, RNA. Talk about the effect there, the impact, is there more to talk about that? Absolutely. So there are many different micronutrients [00:08:30] that are required for functions in your body that involve DNA replication involved DNA repair, preventing DNA damage. Things are all very important because we're making 100 billion new cells every day to make a new cell, we have to replicate the entire genome of that cell to make the daughter cell. And that requires a whole holster of enzymes. So if you don't have enough magnesium for those DNA polymerase to work properly, when ends up happening is that their fidelity is [00:09:00] lessen, meaning they don't work as well and they're gonna likely make more errors in that DNA replication that they're performing. And if they can't repair that error, then when ends up happening is that you can get every rotation and depending on whether that mutation has any functional consequences, sort of random, but the more times as occurs, then the more chances you're having of getting a mutation that can, you know, something that's not good and can either cause cell death or it can also [00:09:30] be something that causes dysregulation of the way your genes are expressed. Speaker 9: So it's very important to make sure you have the right co factors such as magnesium for DNA replication, also in your mitochondria and your mitochondrial DNA. When you make new Mitochondria, this is called mitochondrial biogenesis. It's an important mechanism to boost the number of mitochondria per cell. And this can occur during things like exercise when your mitochondria also have their own genome and they have to replicate this genome. Well guess what? Those mitochondrial [00:10:00] DNA were preliminaries. This also require magnesium. And so if there's not enough magnesium around, you're not making your mitochondria as optimal as you could be in Mitochondria. Play an important role in every single process in your body, including, you know, neuronal function. So that's really important to make sure that your Mitochondria Hobby. Also, this is very relevant for things like aging. These micronutrients like vitamin D gets converted into a steroid hormone that regulates the expression of over a thousand genes in [00:10:30] your body and some of those genes are involved in DNA repair and also in preventing DNA damage. So these micronutrients are extremely important for a variety of different physiological properties that are going on in your body every single day. Things that you can't see when you look in the mirror, we're talking about something that's not an acute deficiency that's going to lead to a clinical symptom like scurvy. Speaker 6: We think bad nutrition is the main thing, accelerating all these degenerative diseases of aging and contributing to these huge medical costs and [00:11:00] all of that. And it's something you can do something about because they're all very cheap minerals that are cheap. So the sourcing of the minerals and vitamins, it's not crucial at this point you think? I don't think so. Yeah. Getting them is the the really the key factor think and I think to really reform people's diet, we're going to need the numbers and we're working to try and show that there's some vulnerable protein that goes first when you're short of McNeese. I [00:11:30] mean you should measure that and then you'll know you're not getting enough and all the consequences or you're disabling all your DNA repair fronts. I'm so whatever. Speaker 9: It is ideal to try and get as many of these micronutrients essential vitamins and minerals that you can from your diet. For example, I personally make a smoothie for breakfast every morning, which consists of Kale, spinach, Swiss carrots, tomato, avocado, berries, and I'm getting a broad spectrum of vegetables and fruits [00:12:00] just from that one smoothie. And I think in addition to these essential vitamins and minerals that we know are in these various plants and fruits, I think there's also a lot of micronutrients in there that we have yet to discover that also may be doing important things. However, it's extremely difficult for people to get all of these micronutrients from their diet. And I think in that instance, supplementation can help fill those nutritional gaps. And we've actually shown that Speaker 6: in general, people in nutrition don't like the idea of pills, but people [00:12:30] are learning about all this. But you shouldn't overdo it. Mae West said too much of a good thing is wonderful, but she was saying about sex, not micronutrients, and particularly for minerals in minerals, there's a sweet spot. Too much can hurt you into little canary, Speaker 5: and that's what you're hoping these next generation devices would help people understand where they are situated within, right? The class of vitamins and minerals. What are they up in? What are they down? Speaker 6: So this may be a decades [00:13:00] worth of science to do this, but we're trying to frame the ideas and say, look, this is where we're going. And it isn't drugs that are gonna help you. It's getting your diet tuned up, your metabolism [inaudible] Speaker 9: your doctor can look at a few different nutrients and vitamin D is one test that they do. But there's a couple of companies that are out there right now such as something called wellness effects. They're measuring a variety of different micronutrients in people's blood, including omega [00:13:30] three fatty acids, vitamin D, magnesium, potassium, calcium. So looking at all these different vitamins and minerals and people are quantifying. It's called the quantified self movement where people are getting their vitamins and minerals and essential fatty acids measured. They're making dietary changes. If they find out they're low in vitamin D or they're low in mega three or they have low magnesium, they're making dietary changes and then about three months later they go back and they'd quantify the levels again so they can physically measure and quantify this, this change that they're making in their diet. And I think really that's the direction [00:14:00] to go. Speaker 6: Yeah, and analytical methods of Guinea. So wonderful that you can do it on a finger prick of blood. I have two entrepreneurs, scientist friends. One of them has put a machine in every hospital in China and he measures couple of dozen proteins of medical importance and the Chinese are subsidizing this. They think it's going to save money. And another friend of mine from Boulder, first one is built routed. The second one is Larry Gold. And he developed [00:14:30] an alternative to monoclonal antibodies and he can measure 1500 different proteins in one fingerprint compliant. I mean, it's fantastic and he's working to get them all right now it's a discovery system, but we're going to discover what protein tells you. You're low in magnesium and what protein tells you you're low in vitaminK or protein tells you low in paradox and then it's all going to go to your iPhone and you'll get the diagnosis. Speaker 6: We'll cut out the doctors [00:15:00] because they don't know much about Olis anyway, and they're too expensive. So it's not drugs you need for all of this. It's tuning up limit tap of the drugs that youthful. I'm not saying that not and for some things that are absolutely essential, but this area of getting your metabolism tuned up, see, people are worried about a pot Papillion a pesticide and it's all irrelevant. We, we published a hundred papers on that in that era, just saying, look, it's all a distraction from the important thing and important thing [00:15:30] is all these bad diets where eating and obesity isn't just calories in, exercise out a beach. People are starving and what this starving for vitamins and minerals because they're eating sugar and carbohydrate and every possible disease of aging is accelerated and hippies and plus huge costs, years of expensive diabetes and heart disease and cancer, you name it, it's been linked to obesity. So I think it's a big [00:16:00] opportunity to tune people up. Speaker 8: Spectrum is a public affairs show on k a l x Berkeley [00:16:30] is this part one of a two part interview with Bruce Ames and Rhonda Patrick. Speaker 9: So Rhonda, the recent paper you published on vitamin D explain that. So vitamin D gets converted into a steroid hormone in your body and the steroid hormone can regulate this expression [00:17:00] of between 900 and a thousand different genes. And the way it does that is that there's a little telltale sequence in your gene and it's basically a six nucleotide sequence repeat that's separated by three nucleotides. And this nucleotide sequence itself can determine whether or not vitamin D will turn on a gene or turn off aging. And so vitamin D can do both of these where it turns on genes and turns off genes. Well, what we found is that there's two different genes that encode for Tryptophan hydroxylase, [00:17:30] which is the rate limiting enzyme that converts trip to fan into Serotonin. There's one that's in the brain called Tryptophan hydroxylase too, and there's one that's outside of the blood brain barrier in tissues like Mosley got also in your t cells and your Peniel gland and placenta tissue if you're woman, and this is called Tryptophan hydroxylase one and what we found is that both of these genes have what's called a vitamin D response element that tell a sequence I was telling you about. Speaker 9: However, they had [00:18:00] completely opposite vitamin D response elements. One, the one in your brain had an activation sequence turn on and the one in the gut had a repression sequence. The turnoff sequence, which suggested that vitamin D hormone was controlling the expression of these two different genes in opposite directions. Vitamin D's important to turn on Tryptophan hydroxylase and two and your brain so you can make serotonin and it's important to turn it off and your gut to blunt the production of Serotonin in your gut. Serotonin in your gut. Too Much of it causes GI inflammation. [00:18:30] This was a really cool finding because there was a recent paper where they found that autistic individuals, 90% of them had some abnormal tryptophan metabolism and they didn't really identify what it was, but sort of like an Aha moment where it was like trick to fan metabolism. Well, chuck did fan, you need to make Serotonin, and so I started doing some reading and sure enough, there's a whole literature connecting Serotonin to autism. Speaker 9: Serotonin is made in your brain. It's an important neurotransmitter, but during early, early brain development, [00:19:00] it is a brain morphogenic meaning it actually is a growth factor that guides the neuronal proliferation, the development, the migration of neurons to different regions in the brain. It plays an essential role in shaping the structure and the wiring of the early developing brain. And so not having enough serotonin in early, early brain development in Utero can lead to very aberrant brain morphological and functional consequences. You know, this was kind of like, wow, well what if you're not getting enough vitamin D during that critical [00:19:30] period, which is important to activate that gene that converts Tryptophan into Serotonin? Is it possible then that you wouldn't be making enough serotonin in that early brain and therefore you wouldn't have a normal brain development? Also, the Serotonin in the gut can cause a lot of GI inflammation and also quite a few autistics have high GI inflammation. Speaker 9: Also, they have high levels of Serotonin in their blood. There's something that we call the Serotonin anomaly where they've measured brain levels of Serotonin autistics from SMRI and have also measured blood levels [00:20:00] of Serotonin. And there was sort of this weird dichotomy where autistics had high levels of Serotonin in their blood, but they had low levels in their brain and so it was like, well, why is that? Why would they have high levels in their blood, the low levels in the brain and we think we found a mechanism why if you're low in vitamin D, your vitamin D won't be turning on the one in your brain and you won't be making enough Serotonin in your brain and it won't be repressing the one you've got and you'll be making too much and you've got this sort of a a really cool finding. We also in our paper discuss how estrogen can [00:20:30] activate Tryptofan hydroxylase to in the brain pretty much the same way vitamin D does also a steroid hormone and the sequences, the receptors bind to a somewhat similar under dug out of the literature that people showed. Estrogen can turn Speaker 6: on the Messenger RNA for the brain enzyme making serotonin in girls, but it's not doing it in boys, which explains why five times as many boys get autism as girls. [00:21:00] Anyway, she worked out all this mechanism. We kept on explaining one thing after another render would come in every week, hopping up and down. Look what I found and look what I found and I think she walks on water, but she did this wonderful scholarship, which is a good metaphor, but she used to be a surfing instructor when she was incentive. Speaker 9: It's pretty exciting. It was largely theoretical work where we did find a underlying mechanism to connect these dots. So we're hoping now that people in the field are going to continue on and look even deeper. Speaker 6: So [00:21:30] what we think we know is how to prevent autism. But what we are not sure of is whether you can give vitamin D to people who have autism and help some of the symptoms. Uh, biggest people need to do clinical trials on all of this and they haven't done them right. But now that we have the mechanism, you can do them right. The trouble is drug companies aren't going to make money with vitamin D and they know that. And so [00:22:00] they're trying to develop a new drug. But we're hoping that these biochemicals trip to fain and vitamin D and nowhere to tone and and may get threes, which are all seem to be involved, which you can find out by reading Ramdas paper that that is going to at least give him mechanisms so we can do more focused clinical trials. Speaker 8: [inaudible] [00:22:30] to learn more about the work and Patrick are doing visit their websites, Bruce ames.org and found my fitness.com Speaker 7: oh Speaker 6: papers take a lot of polishing. Basically we're going into all these fields [00:23:00] that we don't know an awful lot about us and that requires a lot of double checking and sending it to experts and getting criticism. Speaker 9: First you have to learn everything and then you'd have to put, make the connections together and then you have to write it and then there's a whole process. It's very, it's a lot of work. Personally, my favorite part of it is the creative part where you just make all the connections and you find things and you start fitting things together and it's like, oh yeah, you know, it's just, it's almost like awesome rush, but then once you've make all those connections and you do that creative work, then you really have to [00:23:30] do all the tedious, hard digging and working diligence. Yes and that it's not as much fun. Then once you have a good theory Speaker 6: you assume no. Is it explaining new things that you didn't expect and right away this idea explains so many things and it was all really lying on the ground and round it just picked it up and put it together.

I get a huge pile of the magazines or journals I subscribe to, like , , or  (and sometimes even grab a book I don't mind destroying) then settle in for a good 30-45 minute sweat session. After about 25 minutes, it get pretty tough as my heart rate and core temperature rapidly rise, and I eventually get so hot that I have to quit reading - and then I simply switch to staring at the wall and doing deep, meditative breathing to sit things out for as long as I can. I pretend I'm some kind of ancient warrior sitting in an Indian sweat lodge, or a prisoner of war tossed into one of those heat torture chambers. Then I take a cold shower and I feel amazing. I've used this strategy to train for everything from racing Ironman in the lava fields of Hawaii to preparing for a tennis tournament in a stifling indoor tennis courts stadium. But why does heat work so well to enhance performance? Can you use heat to build muscle or burn fat? What's the best kind of heat? Saunas? Steam rooms? Those dorky sauna suits? You're about to find out the answers to these burning questions (ha!), and so much more. My guest in today's podcast, (pictured right) has a Ph.D. in biomedical science, a Bachelor’s of Science degree in biochemistry/chemistry, has done extensive research on aging, cancer, and nutrition, she did her graduate research on the link between mitochondrial metabolism, apoptosis, and cancer... ...and she knows a thing or two about heat exposure too, as you can .  Dr. Patrick is currently a postdoctoral fellow at Children’s Hospital Oakland Research Institute, where she conducts clinical trials looking at the effects of micronutrients (e.g. vitamins and minerals) on metabolism, inflammation, DNA damage, and aging. In addition, she is investigating the role of vitamin D in brain function and other physiological functions. She has also done research on anti-aging techniques at the Salk Institute for Biological Sciences. During our podcast, you'll learn everything you need to know about how to use heat exposure to enhance performance, burn fat, and gain muscle. -3 ways getting into a sauna could actually grow new neurons and make you smarter... -The best to use heat to build endurance, build muscle and heal injuries... -How much heat exposure is enough, and how much is too much... -Whether it's really true that you can increase growth hormone inside a sauna... -How heat can help you produce the "runner's high"... -The amazing anti-aging effect of saunas and how it works... -What the best type of heat is, and whether there is a difference between wet heat vs. dry heat vs. sauna suits vs. infrared saunas and mats... -How to ideally combine heat exposure with cold thermogenesis...

In part 1, investigator with the Howard Hughes Medical Institute Michael Eisen talks about his research, the field, and both experimental and computational biology. Eisen is Associate Professor of Genetics, Genomics, and Development in UC Berkeley's Dept. of Molecular Biology.TranscriptSpeaker 1: Spectrum's next Speaker 2: [inaudible]. Welcome to [inaudible] Speaker 1: section, the Science and technology show on k a l x Berkeley, a biweekly 30 minute program bringing you interviews [00:00:30] featuring bay area scientists and technologists as well as a calendar of local events and news. Speaker 3: Good afternoon. My name is Brad Swift. Thanks for tuning in. Today we are presenting part one of two interviews with Michael Eisen and associate professor of genetics, genomics and development in UC Berkeley's department of molecular biology. Iceland employs a combination of experimental and computational methods to the study of gene regulation [00:01:00] using the fruit fly Drosophila melanogaster as a model system. Isen and his colleagues have pioneered genomic approaches in modern molecular biology and our leaders in the emerging field of computational biology. In part one, Michael talks about how he got started in biology and how his research has evolved onto the interview. Michael Isen, welcome to spectrum. Thank you. My pleasure. Would you give us a narrative of how you initiated your research and how your research has [00:01:30] changed to what it is currently? Speaker 4: Okay. Actually, I grew up in a family of scientists. My parents were both biologists, so I always had an interest in biology. But as a kid, my talents were primarily in math and I was a heavy duty math geek and went to college expecting to be a mathematician and took this freshman calculus class and all the hardcore math geeks tuck. And I did fine. I did well in the class, but [00:02:00] there were several people in the class who were clearly a notch better than me in a way that I think you only can realize and you know, basketball and mathematics at the age of 18 that you're not destined to be the best. And I think math is a field where if you're not the best, it's just kind of boring. And so I stayed as a mathematician and math major in college, but I started increasingly taking a lot of biology classes and had more or less, you know, realized that biology was what really captured my, my attention and [00:02:30] my heart. Speaker 4: And so I went to graduate school but had the idea that I'm interested in biology, but I'm really good at math. So there must be some way of combining these two things. And so I entered a graduate program in biophysics, which is sort of a place where people who are interested in biology maybe haven't taken all the prereqs for a normal biology department but also have a quantitative background go cause. And so, you know, in the way that people sort of drifted into things, I drifted into working on protein structure and [00:03:00] did my phd studying the evolution of the proteins on the surface of flu viruses and using a combination of experimental work and I would hesitate to call it mathematics. It was really just sort of kind of physics and it's, it's a lot of data. You generate a lot of raw data, you generate a lot of data on the coordinates of individual protein molecules and things that they might bind to. Speaker 4: And so it was very natural to start using computers in that work. You know, my background was not in computer science. I programmed as a kid [00:03:30] because my grandfather bought me a computer and I taught myself how to program and I wrote programs to, you know, keep track of baseball statistics and other things like that. In College, I basically never programmed anything in the math department I was in. It was considered not math that you were touching a computer. And so I didn't really do anything with computers until I got to graduate school when you started seeing all this data coming down the pipe. But I wasn't particularly interested in structural biology and I discovered that through six years from graduate school that [00:04:00] although I liked doing it, it wasn't intellectually satisfying, was too small. You're working on one sugar bound to one protein in one virus and I was having trouble seeing how that would expand into something grand and whatever. Speaker 4: You know, the ambitions of, uh, of a graduate student wanting to do something big. And I got lucky in the way that often happens in that my advisor had a colleague he knew from an advisory board. He sat on and he was coming into town because his brother was getting some honorary degree [00:04:30] and I met him in his hotel room, Austin. And he had with him, uh, glass microscope slide onto which had been spotted down little pieces of DNA, each of which corresponded to one gene in the yeast genome. So it's about 6,000 genes in the yeast genome. And you could see them because there was still salt in the spots, but it was a very evocative little device. You could sort of hold it up in front of the sun and you could see the sun sort of glittering on all these little spots. Speaker 4: You could just see the grandness of [00:05:00] the device. Didn't know how people were using them. I didn't know what they would be used for. I didn't know what I would do with them, but I was sort of drawn in by the scale of it all. The idea that you could work on everything at once and you didn't have to choose to work on just one little thing and disappear into a little corner and study. Just that. And so my advisor said, oh, you really should go do this. They need someone who's, you know, understands biology, but can deal with the computational side of things. It's clear that this was going to generate a lot of data [00:05:30] and that, you know, he was right. I mean this was a field that really was in great need of people who understood the biology but could work well in the quantitative computational side of things. Speaker 4: So I packed up and moved to Stanford with a short stint as a minor league baseball announcer in between. Really it was just a very fortuitous time to have gotten into this new field. I mean, the field was really just beginning. So this was in 1996 the first genomes been sequenced, they were microbes, there's bacteria and yeast [00:06:00] and so forth. And we were just getting our first glimpse of the scale of the kind of problems that we were going to be facing in genomics. But what I loved about this device, which is a DNA microarray, it's the sort of became a very hot tool in biology for a number of years was that it wasn't just a computer, it wasn't just data in a computer. It actually you were doing to do experiments with this. I'm interested in biology cause I liked living things. I like doing experiments, I like seeing things and I didn't want to just disappear with someone else's data and [00:06:30] analyze it. Speaker 4: So I went to Stanford to work on these and it really was just this awesome time and we were generating huge amounts of data in the lab and not just me. There were, you know, dozens of people generating tons of different types of experiments and so forth. And we lacked any kind of framework for looking at that data constructively. You couldn't look at those experiments and figure out by looking line by line in an excel spreadsheet at what gene was expressed, at what level and what condition. It just wasn't [00:07:00] the way to do it. And so my main contribution to the field at the time was in bringing tools for organizing the information and presenting it visually and being able to interact with that kind of incredibly complicated data in a way that was intuitive for people who understood the biology and allowed them to go back and forth between the experiment in the computer and the data and really try to make sense of what was a huge amounts of data with huge amounts of information, but something nobody had really been trained to [00:07:30] look at. And so it was there that I really realized kind of the way I like to do science, which is this constant back and forth between experiments on the computer. In my mind and in what I try to teach people in my lab. There's no distinction between doing experiments on the bench or in the field or in a computer that they're just different ways of looking at biology. Speaker 3: This is spectrum line KALX Berkeley. Today, Michael [00:08:00] I's associate professor at UC Berkeley explains his research in developmental biology. Speaker 4: On the basis of that time at Stanford, I got a job at Berkeley and what I did when I started my lab at Berkeley was really tried to focus on one problem. I mean I had been working on a million different problems at Stanford where we had a huge group and a million different people working on, and I was sort of moving around from problem the problem and helping out people with their data or thinking of different experiments. And when I came to Berkeley, I really [00:08:30] wanted to focus on one problem. And the problem that had intrigued me from the beginning of working on the microarray stuff was figuring out how it is that an animal's genome, which is the same essentially in every cell in the body, how it instructs different cells to behave differently, to turn on different genes and to acquire different properties. And so partly because of the influence of people here at Berkeley who were working on fruit flies, I switched my research program to work on [inaudible] when I started my lab at Berkeley, the genome of that [00:09:00] had just been sequenced and I liked working with animals. Speaker 4: I like having something that moves around and you know, had some behaviors and so the lab started to work on flies and pretty much since then that's what we've worked on. That's sort of the story of how I got to where I am. So your research then is you're looking at flies over time? Yeah, I mean, I mean I see how the genes are expressed. I'd say we're looking at classified more as developmental biology in the sense that we're looking at how genes are expressed over time during the lifespan of a lie. To this day, [00:09:30] we can't look at a newly sequenced genome and say, oh well this is what the animal's going to look like. That is, I couldn't tell you except sort of by cheating and knowing, comparing it to other genomes. If I, you gave me a fly genome, I look at it, I wouldn't know it was a fly or a worm or a tree or it's just the way in which the organism acquires it. Speaker 4: Things that make them interesting, their form, their appearance, their function. We have just the tiniest scratch of understanding of how that works. And so it's, for me, the most [00:10:00] interesting problem in biology is how do you get in a complicated structure like an animal out of a single cell. And how is that encoded in a genome sequence? I mean it's a fascinating mystery that I thought, you know, when I first started doing this I thought we'd have solved that problem by now. Not Easily. You know, because we had all this new data, we had the genome sequences we could measure. And a lot of what my lab does is actually measure which genes come on when, during development and try to understand for individual genes where that's been encoded in the genome [00:10:30] and how that happens. And I just sort of figured, well, you know, the problem for all these years was not that the problem was that hard. Speaker 4: We just didn't have the right data to look at this problem. And now we can do these experiments. I can sequence the genome of a fly and in a day I can characterize which genes are turned on when during development. And I sort of naively thought, well, we'll just sort of put it into a computer and shake things up and be clever and we'll figure out how these things are related to each other. And I mean now it's laughable that I would've ever thought that, but it was a very, very complicated thing. It's a process that's [00:11:00] executed by very complicated molecular machines operating in a very complicated environment or the nucleus and it, you know, we really don't understand it very well. We've learned a lot, but it's not a problem. We really understand. And so what is it that you've accumulated in terms of knowledge in that regard? Speaker 4: What do you think you've learned? A small amount of this is coming from my lab, but this is a whole field of people looking at this. But that we know the basic way in which that information is encoded in the genome. [00:11:30] We know that there are tuneable switches that can turn genes on and off in different conditions. And we know basically what molecular processes are involved in doing that in the sense that we know that there are proteins that can bind DNA in a sequence specific manner. So they will stick only to pieces of DNA that contain a motif or a particular code that distinct for each of these factors. In flies, there's several hundred of these factors and for humans that are several thousand of these factors that bind DNA in a [00:12:00] sequence specific manner, and they basically translate the nucleotide sequence of the genome into a different kind of code, which is the code of proteins bound to DNA. Speaker 4: And we know from a million different experiments that it's the action of those proteins binding to DNA that triggers the differential expression of genes in different conditions. So if you have a particular proteins, these are called transcription factors. If you have one in a cell at high levels than the genes [00:12:30] that are responding to that factor will be turned on in that cell. And if there's another cell where that protein isn't present, the set of genes that responds to it won't be turned on. So we know that as a general statement, but working out exactly how those proteins function, what it is that they actually do to turn a gene on and off, how they interact with each other, what conditions are necessary for them to function. All of those things are, I wouldn't say we know nothing about it, but they're very, [00:13:00] very poorly understood. Speaker 4: A lot of this sort of simple ideas that people had of there being a kind of regulatory code that looked something like the protein code that we're, you know, amino acid code that people are familiar with, right, that there'll be a genetic code for gene regulation. The idea that that's true is long disappeared from our thinking in the sense that it's much more like a very, very complicated problem with hundreds of different proteins that all interact with each other in a dynamic way. Something bind recruits, something else. [00:13:30] The thing it recruits changes the coding on the DNA and essence to a different state and then that allows other proteins to come in and that somehow or another that we still really don't understand. You eventually reach a state where the gene is turned on or turned off depending on what these factors are doing and you know, while there's lots of models for how that might function, they're all still tentative and we're getting better. The techniques for doing these kinds of experiments get better all the time. We can take individual pieces of or Sophala embryo [00:14:00] and sequence all the RNA contains and get a really complete picture of what's turned on when the technology is improving to the point where we can do a lot of this by imaging cells as amazing things we can do, but still the next level of understanding the singularity in our understanding of transcriptional regulation is still before us. Speaker 3: Spectrum is on KALX, Berkley alternating Fridays today. Michael [inaudible], associate professor at UC Berkeley [00:14:30] is our guest. In the next section, Michael describes the challenges his research poses Speaker 4: and is the task then the hard work of science and documenting everything's, yeah. Mapping a little bit about just observing. I mean, I'm a big believer in observational science that what's limited us to this has been just our poor tools for looking at what's going on. I mean we still hard to visualize the activity of individual molecules within cells, although we're on the precipice [00:15:00] of being able to do that better. So yeah, it's looking and realizing when the paradigms we have for thinking about this thing are clearly just not sufficient. And I think the fields get trapped sometimes in a way of thinking about how their system works and they do experiments that are predicated on some particular idea. But you know, usually when you have an idea and you pursue it for quite a long time and it doesn't pan out, it's because the idea is wrong. Speaker 4: And not always, but I think the transcriptional regulation field has been slow to adapt [00:15:30] to new sort of models for thinking. Although that is changing, I think that there's a lot of activity now and thinking about the dynamics of DNA and proteins within the nucleus. You know, we tend to think about DNA as kind of a static thing that sits in the nucleus and it's a, it's sort of read out by proteins, but really much more accurate as to think of it as a living kind of warned me like thing in the nucleus that gets pulled around to different parts of the nucleus and where it is in the nucleus is one way in which you control what's turned on and off. And I think people are really [00:16:00] appreciating the importance of this sort of three-dimensional architecture of the nucleus as a key facet and controlling the activity that there's, the nucleus itself is not a homogeneous place. Speaker 4: There is active and inactive regions of the nucleus and it's really largely from imaging that we're learning how that's functioning and you know, we as the whole field and are there lots of collaborators and people who are doing work? Yeah, I mean I'd say oh yeah. I mean it's a, it's an active feeling. Pay Attention to [00:16:30] oh yeah. So it's an active, if not huge field and not just in flies. I mean, I think it's transcriptional regulations of big field and in particular in developmental biology where amongst scientists we're interested in how animals develop. It's long been clear that gene regulation is sort of sits at the center of understanding development and so people interested in developmental biology and have long been interested in transcriptional regulation and I think everybody's got their own take on it here. But yeah, it's a very active field with lots of people, including several other people at Berkeley who are doing really [00:17:00] fascinating stuff. Speaker 4: So it's not out in the wilderness. This is not the hinterlands of science, but it's um, it's a nice field to work in about appropriate size. Our annual meetings only have a thousand, a few thousand people. It's not like some of these fields with 25,000 people. I can realistically know all the people who are working on problems related to ours and I literally know them and I know what they're doing and we sort of exchange ideas. So I like it. It's, it's nice community of people. [00:17:30] Is the field driving a lot of tool development? Absolutely. I say, this is something I really try to encourage people in my lab and people I trained to think, which is when you have a problem, you should be thinking not what am I good at? What can I apply to this problem? What technique has out there that would work here? Speaker 4: But what do I need to do? What is the right way to solve this problem? And if someone else has figured out how to do it, great, do it. But if they haven't, then do it yourself. And I think that this applies sort of very specifically [00:18:00] to doing individual experiments, but also to this broader issue we were talking about before with this interplay between computation and experiment. I think too many people come into science graduate school or wherever, thinking, well, I'm an experimentalist or I'm a computational biologist or whatever. And then they ask a question and then the inevitably hit the point where the logical path and pursuing their question would take them across this self-imposed boundary. Either you're an experimentalist who generated data and you're not [00:18:30] able to get at it in the right way and therefore, you know what you really need to be doing is sitting at a computer and playing around with the data. Speaker 4: But if you view that as a boundary that you're not allowed to cross or you're incapable of crossing, you'll never solve it because it almost never works. You almost never can find somebody else no matter how talented they are. Who's as interested in the problem that you're working on as you are. And I think that's a general rule. Scientists should feel as uninhibited about pursuing new things even if they're bad at it. It's certainly been a mantra [00:19:00] I've always tried to convey to the people in my lab, which is, yeah, sure, you come in with a computer science background and you know you're a coder and you've never picked up a pipette or grown a fly. But that's why the first thing you should do in the lab is go grow flies and vice versa. For the people who come in perfectly good in the lab but unable to do stuff in the computer, the first thing you should do is start playing around with data on the computer and it doesn't always work and not everybody sort of successfully bridges that gap, but the best scientists in my mind are ones who don't [00:19:30] circumscribe what they're good at. Speaker 4: They have problems and they pursue them. When something like visualization, is that a bridge too far to try to embrace that kind of technology? I've always done that. I mean I almost every time I do an analysis in the computer, I reduce it to picture some way or another. You know, because of the human brain, no matter how fancy your analysis is, the human brain is just not good at assimilating information as numbers. What we're good at as thinkers is looking at patterns, [00:20:00] finding patterns and things, looking at looking at images, recognizing when patterns are interesting and important, and there's a crucial role for turning data into something the human brain can pull in. And that's always, for me, one of the most fun things is taking data that is just a string of numbers and figuring out how to present it to your brain in a way that makes some sense for it and the refinement of it so that it's believable. Speaker 4: Yeah, and so then you can do it over and over and over and get the same result. Yeah, and all, I mean it is one of the dangers [00:20:30] you deal with when you're working with, when you're relying on human pattern recognition is we're so good at it that we recognize patterns even when they don't exist. There's a lot of statistics that gets used in modern biology, but often people I think use it incorrectly and people think that statistics is going to tell them what things are important, what things they should be paying attention to. For me, we almost entirely used statistical thinking to tell us when we've fooled ourselves into thinking something's interesting, you know, with enough data and enough things going on, you're going [00:21:00] to find something that looks interesting there and having a check on that part of your brain that likes to find patterns and interesting things is also crucial. Speaker 4: You know, I think people understand that if you flip a coin three times, it's not that we are trying to land on heads, but they have much, much harder time thinking about what happens if you flip a coin a billion times. We're struggling with this in biology, this transformation from small data to big data, it taxes people's ability to think clearly about what kinds of phenomena are interesting and aren't interesting. [00:21:30] Big Data is sort of the promise land now for a lot of people. Yeah. I'm a big believer in data intrinsically. If you're interested in observing things and interested in understanding how they work, the more you can measure about them better. It's just that's not the end of the game. Right? Just simply measuring things that doesn't lead to insight. Going from observing something to understanding it. That's where the challenges and that's true. Whether you're looking at the movement of DNA in a nucleus or you're [00:22:00] looking at people by a target, right? Like the same. It's the same problem. Speaker 3: This concludes part one of our interview with Michael [inaudible]. On the next spectrum, Michael Eisen will explain the Public Library of science, which he [inaudible]. He will give his thoughts on genetically modified organisms and a strategy for labeling food. He discusses scientific outreach and research funding. Don't miss him now.

This February 12th you are eligible to no-name blood if you are in good health way, at least 110 pounds and are 17 years or older. You can [00:23:30] also check out the eligibility guidelines online for an initial self screening if you're not eligible or you prefer not to donate blood. There are other ways to support campus blood drives through volunteering, encouraging others and simply spreading the word. You can make an appointment online, but walk ins are also welcome. The blood drive will be on February 12th and the alumni house on the UC Berkeley campus will last from 12 to 6:00 PM you can make an appointment or find more information at the website. [00:24:00] Red Cross blood.org using the sponsor code you see be February 13th Dr. Bruce Ames, senior scientist at the Children's Hospital Oakland Research Institute will speak at a colloquium on the effects that an inadequate supply of vitamins and minerals has on aging. Speaker 6: Dr Ames posits that the metabolism responds to a moderate deficiency of an essential vitamin or mineral by concentrating on collecting the scarce proteins [00:24:30] to help short term survival and reproductive fitness, usually at the expense of proteins important for longterm health. This is known as triaged theory. Dr Ian Discuss ways in which the human metabolism has evolved to favor short term survival over longterm health. He will also present evidence that this metabolic trade-off accelerates aging associated diseases such as cancer, cognitive decline, and cardiovascular disease. The colloquium will be on February 13th from 12 [00:25:00] to 1:15 PM on the UC Berkeley campus in five one oh one Tolman hall February 16th the Monthly Science at Cau Lecture series will hold a talk focusing on the emerging field of synthetic biology, which applies engineering principles to biology to build sales with new capabilities. The Speaker, John Dabber is a mentor in the international genetically engineered machines competition or ai-jen and a UC Berkeley professor, [00:25:30] Dr Debra. We'll discuss the new technique created in J key's link's lab to make low cost drugs to treat malaria. He will also introduce student members of the UC Berkeley Igm team who will discuss their prize winning project. The free public event will be on February 16th from 11:00 AM to 12:00 PM will be held on the UC Berkeley campus in room one oh five of Stanley hall Speaker 5: on Tuesday the 19th how long now and Yearbook Buenos Center for the Arts Presents. Chris Anderson's talk [00:26:00] on the makers revolution. He describes the democratization of manufacturing and the implications that that has. Anderson himself left his job as editor of wired magazine to join a 22 year old from Tijuana and running a typical makers firm. Three d robotics, which builds is do it yourself. Drones, what based collaboration tools and small batch technology such as cheap 3d printers, three d scanners, laser cutters and assembly. Robots are transforming manufacturing. [00:26:30] Suddenly large scale manufacturers are competing, not just with each other on multi-year cycles are competing with swarms of tiny competitors who can go from invention to innovation to market dominance. In a weeks today, Anderson notes there are nearly a thousand maker spaces shared production facilities around the world and they're growing at an astounding rate. The talk is seven 30 to 9:00 PM at the Lam Research Theater at the Yerba Buena Center for the arts at 700 Howard Street in San Francisco. Speaker 5: [00:27:00] Tickets are $15 for more information, visit long now.org now to new stories presented by Renee and Rick. The Federal Communication Commission has released a proposal to create super wifi networks across the nation. This proposal created by FCC Chairman Julius Jenna Koski, is it global first, and if approved, could provide free access to the web in every metropolitan area and many rural areas. The powerful new service could even allow people [00:27:30] to make calls for mobile phones using only the Internet. A robust public policy debate has already sprung up around the proposal, which has drawn aggressive lobbying on both sides. Verizon wireless and at t, and t along with other telecommunications companies have launched a campaign to persuade lawmakers. The proposal is technically and financially unfeasible. Meanwhile, tech companies like Google and Microsoft have championed the ideas sparking innovation and widening access to an [00:28:00] increasingly important resource. We can add this to the growing list of public policy debate over our changing and complex relationship with the Internet. Speaker 5: A team at McMaster university as reported in the February 3rd issue of nature chemical biology that they have found the first demonstration of a secreted metabolite that can protect against toxic gold and cause gold. Biomineralization. That's right. Bacterium Delphia, [00:28:30] a seat of [inaudible] take solutions continuing dissolve the gold and creates gold particles. This helps protect the bacteria from absorbing harmful gold ions, but it also might be used to harvest gold. The researchers found genes that cause gold, precipitation, engineered bacteria that lack these jeans and observed that these bacteria had stunted growth and that there was no gold precipitation. They also extracted the chemical responsible [00:29:00] for the gold mineralization naming it delftibactin a, the molecule creates metallic gold within seconds in Ph neutral conditions at room temperature. Gold exists in extremely dilute quantities in many water sources and the bacteria or the metabolite might be used to extract gold from mine. Waste in the future.
