Anti-Racist Science Education
"All right today in the show. We're unsmiling what's not working in science education around representation and racism and how to teach science in a more inclusive way and idea from listener and scientists esther kunle yes so thanks to esther. We went looking for k. Through twelve teachers teaching at the intersection of science and racial justice at all grade levels. And i want to start with. Let me see a fears. She's a post doctoral fellow in the collaborative for stem education. And outreach vanderbilt okay. She's a black scientist. Helping out in science classrooms in tennessee. Among fifth graders at this one particular school she is a total rockstar to walk into a classroom. And they'll be like dr. Yeah it's me. It's me everyone you know know autographs thing. We lit up each others world. Our saying that let me see a drops into fifth seventh and eighth. Grade science classrooms like a real life. Miss frizzle okay. I'm not kidding. You she wheels the cart between classes clattering with beakers and different very interesting looking chemicals and students. They're so intrigued. They run up to her on our like number my wife just all that stuff and then when she's in the classroom let me see a doesn't just help them run experiments. She'll also delve into the ethics of designing an experiment. Okay she'll talk about how wrong. The tuskegee study was which is win. Scientists studied syphilis in black men and withheld treatment. Sushi's like introducing bioethics to kids as important part of the curriculum. Yup scientists are presented as very human herself included and her students can totally handle these conversations. We see what's happening with this generation with them protests. And they're speaking out and they're not having it they're not gonna they're not going to allow us to continue to destroy her and her point is that if science teachers can tap into that compassion and that curiosity and show the way that scientists have messed up. Kids might take up an interest in science. I love it and if we can't do that then we are gonna lose on. And i think it's hard were minority kids. They already don't see themselves as the teacher or the prisoners doing the science so that already kind of puts up a block of well. That's just what the old white main with crazy hairdo and so another thing. Let me see a does is named drop scientists of color as often as possible. She'll talk about astrophysicist. Did eisler medical physicist hadean ecole green astronauts. Joseph akaba and jeanette epps. She designed paper rocket lesson around them and this helps kids develop a mental picture of a career in stem beyond a doctor or a dentist. This is so cool because it's not just about teaching science history right. It's also helping. Students see themselves as scientists and for gretchen craig. Turner the next teacher. I want to introduce you to this. Level of engagement becomes even more important as students get older and start to get into their teenage years and develop their own opinions their own opinions about science. Yeah to be critical of it. Oh yeah that was not in my k. through twelve science education hers either. I don't remember a lot of writing or Opinions being part of science in fact it was very much i believe taught. The opinions didn't belong in science right that it was supposed to be a
"doctoral fellow" Discussed on Brothers of the Serpent Podcast
"The researchers used a machine learning algorithm. That was originally developed to analyze distant galaxies to probe the mysterious phenomenon occurring deep within our own planet according to paper published on Thursday in science but that was Thursday. Any moons ago in June. So I guess this isn't this isn't that old. One of these enormous anomalies located deep under the I should have looked up how to say this marquesses. I'll just go with marquesses under the Marquess islands. has never been detected before while another structure beneath Hawaii was found to be much larger than previously estimated. Scientists led by Kim a seismologist and post doctoral fellow at the University of Maryland Fed seismic grams captured from hundreds of earthquakes that occurred between nineteen, ninety, two, thousand, and eighteen into an algorithm called sequencer. While seismological studies tend to focus on relatively small data sets of regional earthquake activity sequencer, aloud Kim and his colleagues to analyze seven thousand measurements earthquakes each with the magnitude of at least six point five that shook the subterranean world under the Pacific. Ocean. Within the past three decades. This study is very special because for the first time, we get to systematically look at such a large data set that actually covers more or less the entire Pacific basin Kim said in a call. Though scientists have previously mapped out structures deep inside the earth this study. Presents a rare opportunity to bring everything in together and try to explain it in a global context he noted. Earthquakes create seismic waves that traveled to Earth's interior where they become scattered and distorted by structures deep inside our planet. These warped patterns are captured in seismic grams, which are recordings of wave activity inside earth enabling seismologist to capture rare glimpses of earth inaccessible underworld. Maybe it is accessible though don't know. The team of focused on seismic grams produced by shear waves s waves. That travel along the boundary between Earth's color and the lower portion of the mantle that borders it. These waves are the slower secondary waves that follow the initial tremors made earthquakes which are called primary waves or p waves, and they generally produce clearer signals. We normally like to use s ways because they are larger in amplitude and the data is more or less clean because there is less wave traffic said Kim. In particular, the team looked for the shear waves diffraction along the core mantle boundary. Because it detracts along that surface. It is a great place to look for these tiny structures on top of the core Mantle Boundary Kim noted. When the shear waves hit these structures, they produce a type of echo like signature known as a post cursor. These echoes indicate the presence of anomalies deep inside. Earth called ultra low velocity zones or you lvs's which are dense patches on the cooler mental boundary..
Want To Dismantle Racism In Science? Start In The Classroom
"All right today in the show were unscrewing what's not working in science education around representation and racism, and how to teach science in a more inclusive way and idea from listener and scientists Esther Kunle yes. Thanks to Esther we went looking for K., through twelve teachers teaching at the intersection, of Science, and racial justice at all grade levels I want to start with. Let me see fears. She's a post doctoral fellow in the collaborative for stem education and outreach at Vanderbilt. Okay. She's a black scientist. Out in science classrooms Tennessee in among fifth graders. At this one particular school, she is a total rockstar. So walk into a classroom and they'll be like. Yeah it's me. It's me everyone autographs today. We lit up each others world. Our say, let me see a drops into fifth seventh and eighth grade. Science classrooms like a real life. Miss Frizzle I'm not kidding you. She wheels the cart between classes clattering with beakers and different very interesting looking chemicals and students. They're so intrigued they run up to our like remind wife we've. Just all that stuff and then when she's in the classroom, let me see a doesn't just help them run experiments. She'll also delve into the ethics of designing an experiment. Okay. She'll talk about how wrong the Tuskegee study was, which is winning scientists studied syphilis in black men and withheld treatment Sushi's like introducing bioethics to kids as important part of the curriculum. Yup. Scientists are presented as very human herself included and her students can totally handle these conversations. We see what's happening with this generation with them protest and they're speaking out on, they're not having it. They're not. They're not going to allow us to continue to destroy their and our point is that if science teachers can tap into that compassion and That curiosity and show the way that scientists have messed up. Kids might take an interest in science I love, and if we can't do that, then we are GonNa lose them and I think it's hard for minority kids. They already don't see themselves as the teacher or the Christmas doing the science. So that already unemployed simple block of well, that's just what the old white man with the crazy hairdo. and. So another thing let me see Ya does is namedrop scientists of color as often as possible. She'll talk about a physicist did Eisler medical physicists had he and Ecole, green astronauts, Joseph Akaba, and genetic APPs. She designed a paper rocket lesson around them and this helps kids develop a mental picture of a career in stem beyond a doctor or a dentist. This is so cool because it's not just about teaching science history, right? It's also helping students see themselves as scientists and for Gretchen Craig. Turner. The next teacher I, want to introduce you to. This level of engagement becomes even more important students get older and start to you know get into their teenage years and develop their own opinions their own opinions about science. Yeah. You know to be critical of it. Oh. Yeah. That was not in my k. through twelve science education hers either I don't remember a lot of writing or opinions being a part of science. In fact, it was very much I believe taught the opinions didn't belong in science right that it was supposed to be a right answer Gretchen teaches. At Burlington Edison High. School. In Washington state she is white and her classroom to be as inclusive as possible and to reflect the diversity of the student body and in her first year of teaching a biotech class. This was back in two thousand, ten in English teacher gave her a copy of the book. The immortal life of Henrietta lacks was like you should teach the steer students. Yeah. So the history of the Hilo Cell Line Yep. So Henrietta, lacks cancer cells were used for years by scientists without her family's knowledge cells that. One. Of the most important cell lines in medical research, her case raises so many questions about patients, rights. Yep questions raised in this book. So Gretchen got a bunch of hardcover books for her class and we read it and. It shaped how I teach in tremendous ways because the students responded to it. So strongly, you know they were excited maybe not at first I still get a lot of Turner. This isn't an English class, right but but they got into it. So into it, it is a six week unit the book in a Science Class. STUDENTS DO SELL labs while they're reading and they journal to. Okay so they're jotting down notes on different themes like medical apartheid informed consent lab science, and at the end they write a big paper and also oftentimes in class, there will be students who who's own families have experienced medical apartheid in the. Effects of that and I think some of the students and see themselves in the story of the lacks family. The conversations become really personal and probing not. You know necessarily what you'd expect in science class but exactly what Gretchen is hoping for well I, think what you know many young people ultimately want from their teachers is to be seen into be heard. And so if the science curriculum. if they feel seen and heard through that curriculum, they're more invested. So when her students learn about genetic testing, Gretchen includes a film about the innocence project and they're a group that uses DNA testing to exonerate those who've been wrongfully imprisoned. And Gretchen has her students, write poetry and songs as kind of oaths to those wrongfully convicted my blood, my skin, my hair, all held the key to my freedom DNA. My eyes glazed over desperate for relief with a pain. I now understood my hand reaches for I. Don't Know How often you're around teenagers. But the. Teenagers of this just tremendous sense of justice and what is right you know, and so those conversations are often very passionate for students But it's also the world that they live in. Wow I mean kwong, there's so many things in here. That are so powerful in and I know there's a lot of science teacher who listened to shortwave who might want to incorporate racial justice in history into their teaching too I mean, where do they look well Gretchen and let me see a- had the same advice which is at teachers should fill in the gaps in their own racial understanding I learn about the history of science or their field, and that's exactly what the last teacher I spoke with is doing. Vigia satiety is a college professor at University of North Carolina at Chapel Hill, and looking critically at her own field statistics has been hard painful work. You know I honestly I just feel like I'm I missed something that was really important to learn about my discipline and I'm I'm a little bit mad at myself for not being curious on my own to figure out the origins of things and she has been startled to realize the full extent to which modern statistics draws upon the work of you. Genesis Francis Colton Karl Pearson Ronald Fisher. Some of the most foundational tools and stem like the normal distribution curve were applied to support their racist and eugenicist theories tools that we. Use today, but we don't really stop to think about the people who created them and why they created them. So the is trying to stop to teach yourself where these came from, but to not rush the process with some slapdash curriculum, she wants to incorporate these historical into her classes with care I want to give it the space deserves and of course, and not not to feel like this awkward add on that people can optionally engage in in a way that centers the students Vigie like all the teachers I spoke with designs, her classes by asking herself who's being left behind with this material, and how can I bring them along? That's what can be gained from. And anti-racist science education I think all of us in our minds have been in or heard of course where the professor says look to the laugh looked the right. One of you won't be here at the end of this time or you know something horrible this should not ever be uttered in a classroom. I say look to your left to your right like I. Want you all to stay. I want you all the love my field as much as I. Love my field because there's so many interesting things you could do with it and we really could use your wonderful mind and our discipline. We could use your perspective and the things that you bring. So basically to change science, we have to change how we teach science. To fix the lab gotta fix the classroom.
Costly refined coal subsidy is failing to achieve air pollution goals
"Every year, the US government provides about a billion dollars in tax credits to companies that produce what's known as refined coal. It's chemically treated coal that when burned supposedly admits less than the pollution that can harm human health but there's a problem companies qualify for the tax credit using lab tests, which could differ dramatically from what's actually happening in the field at the power plants where the coal is burned. Brian pressed is a post doctoral fellow at a research nonprofit called resources for the future he studied the actual air pollution emitted when companies burn refined coal we look at actual field missions you know what's happening at the power plant and we're finding that the emission reductions fall far short of what the tax law says that they should be getting. What's more he says, the tax credit can make it profitable for. Some older power plants to keep burning coal for longer. So it may actually increase carbon pollution and worsen global warming. He says, it's a timely issue because the tax credit is set to expire at the end of twenty twenty one and is a immediate policy question about whether we're going to renew this or whether we should take the funds that would be used for this subsidy, and perhaps he's for a better purpose.
Alaska's Salmon are Shrinking
"Year salmon come home to Alaska's frigid rivers to mate, lay their eggs and die. The. State Salmon runs are some of the biggest in the world but over the past few decades, those big salmon runs have featured ever smaller. Salmon. Talk to people up there has been fishing for a long time and they're definitely able to tell you that we just don't see those really large old salmon used to see Christa a post doctoral fellow at the University of Alaska Fairbanks oaken colleagues at the University of California Santa Cruz, and elsewhere analyzed records of fish size. Going back to the nineteen fifties they included data on some twelve point, five, million, salmon, each of which had. To be measured by someone from the Alaska Department of fish and game, and there's no question about it. Salmon have shrunk sockeye salmon today are two point one percent shorter than their ancestors chum salmon are two point four percent shorter and Coho or three point three percent shorter Chinook or king salmon showed the greatest declines at eight percent. That's an average difference of more than two inches in length. The study is in the journal Nature Communications. The researchers haven't nailed down the exact reasons behind this trend, but they're analysis suggests that climate change and competition with wild and hatchery raised salmon, both play a role. They also discovered that much of the change in body size is due to fish returning from the ocean at a younger age now than in the past. Oak, says fish could be returning earlier because they're reaching maturity faster for some reason or because the ocean has become a riskier place for older salmon to survive what could be happening is the That otherwise would have returned large old. Just making. Whatever the cause this size shift has massive ramifications for people and the Environment Oak and her team calculated that catching smaller fish may have already slashed the value of Alaska's Commercial Salmon Fisheries by twenty one percent. It's also likely reduced the food available to subsistence fishers, many of whom reliance stores of salmon to get them through the long harsh winter by as much as twenty six percent. On the ecological side, the researchers estimated that smaller fish sixteen percent fewer eggs, which could depress salmon populations in the future and the Salmon Bring Twenty eight percent fewer nutrients into the watersheds were they spun according to the study after they breed and die kirk actually fertilize. Freshwater and terrestrial ecosystems with these marine derived nutrients that are really important and that used by all kinds of animals like bears and songbirds even taking up into trees with no single factor to blame for shrinking salmon there's no fix says, but there are still plenty of fish in the sea they're just smaller than they used to be.
Understanding the COVID-19 Data Quality Problem with Sherri Rose
"Welcome to the PODCAST. Thank you for having me. It is great to have a chance to chat with you. I'm looking forward to digging into your background and your research and The things you're doing related to cove it to help out there you know. Let's start at the beginning. How did you become interested in machine learning and in the intersection of that and Healthcare I always was very interested in science and mathematics and physics and I didn't really have a good sense of how you could use that to solve problems when I was going to college and it was during college that I was exposed to this summer. Program called the Summer Institute for training in biostatistics and it really sounded like what I was interested in which was bringing quantitative reasoning thinking to problems in health and public health and I realized very quickly that I needed more than my bachelor's degree in statistics in order to really solve a lot of those problems and I didn't actually get any training in machine. Learning in my bachelor's degree I graduated in two thousand five and the curriculum definitely did not include it at that point and so when I went to graduate school at UC Berkeley in biostatistics. That's where I saw. The the benefit of having really general frameworks in which solve problems. And that's when I started working on non parametric machine learning and having these kind of big picture ways to attack big problems in population health and that was for me. That's been both machine learning in non parametric models for prediction but also causal inference and the driver for me was really the ability to use these flexible tools to solve problems in in healthcare in medicine it must have been helpful having that. Undergrad in stats. It's it's been very helpful. Actually I actually started as a mechanical and Aerospace Engineering Major. And I did not feel very invigorated by the coursework there and I very room and I also was a little frustrated that I was often the only woman in the classes and it just it. There was a lot of reasons why didn't feel like the right fit for me. I ended up taking my second semester in college. Statistics course and I immediately saw how statistics could be used for solving lots of different problems and Engineering Ken as well but for me. The statistics was really how I saw bringing all my interests together. You mentioned non parametric machine learning. What is that? And how does that relate to Both the broader field as well as the healthcare field. If somebody talk about non parametric I mean it. In the very broad statistical sense a non parametric model is a larger model space. Where we're making many fewer assumptions and whereas with parametric models more standard parametric models. We might be making strict assumptions about the functional form the underlying unknown functional form of the data with non parametric. I WanNa really have a large model space. I have a much better opportunity to uncover the truth with my machine learning estimator so many like you're not assuming a normal distribution which has a couple of parameters and a standard deviation it could be anything definitely not definitely not that would be a limiting gumption in your work. Yeah absolutely and most of the data that I work with does not conform to those types of strict assumptions. Talk a little bit more about the scope of your research interests and where you apply machine learning. It sounds like you are interested. Both in the of the systematic issues the healthcare system with the relationships between the providers and the payers as well as clinical issues absolutely so in health services research were really interested in the whole broad scope of the healthcare system that includes cost quality access to providers and services and also health outcomes following care so that clinical piece comes into the health outcomes following care and some of the major areas that I've worked in intersect with the health spending aspects the financing aspects like mental health and Telemedicine and cardiovascular treatments. All of these things intersect within the system that relies on you know the the cost the quality the access to providers. So it's a really having a research program that encompasses both pieces of that can allow you to ask and answer questions in more integrated ways. It's difficult but I find that you if you understand those underlying systems and try and bring them into your work when you're looking at clinical work It can help you inform better answers and when you are looking at those kinds of questions are you primarily trying to understand or influence great questions so a lot of the work that I do. We're trying to understand some kind of phenomena in the system but influence yes in the sense that we're trying to inform policy so understanding the comparative effectiveness of multiple. Different types of treatments. I I would like to understand which treatments have better health outcomes but if we find a particular treatment has a very bad outcomes we want to inform policy to the FDA or to the relevant stakeholder in order to potentially have that treatment removed from market and we're talking towards the end of April Many of us have been some form of another of locked down due to co VID. Did you mentioned that? Your dog may start barking. He may He may my neighbor. Just I think my neighbor is finished cutting the grass. Now you know this. Is You know the Times but it sounds. Like your work intersects with Cova. Did as well. Can you talk about that intersection a little bit? Absolutely a large focus of my work because I'm so integrated in starting with the substantive problem in bringing either existing machine learning tools or developing new machine learning tools to answer those questions. It really there has to be the strong grounding data and the virus pandemic has really eliminated for a lot of people how much we need to care about data. And I I I mean we have misclassification. We have Missing nece in the types of data that we're collecting for Virus both for cases and mortality counts. And these are things that are very very common and most of the electronic health data that we use in the healthcare system where a lot of my work has focused on dealing with some of these types of issues. I mean we use billing claims we use Clinical Records Registry data an on and on and these data types were not designed for research. And so we need to be really aware of the issues in these types of of data and some of the newer forms of data like wearable implantable technology. That people have been very excited about measuring physical activity were now using the current virus pandemic of smartphone location data to try and understand how people are Social distancing with potentially with contact tracing and then digital types of data like Google search trends and twitter data which has been used for different types of research questions in the past now. Google is developing and has released this location. History website. Where they're showing out. Know how we can understand social distancing and so a lot of the data related work that. I've been focused on very relevant to the pandemic understanding our data sources and trying to bring rigorous flexible methods to them specifically. I had been working the last two years with my now former post-doctoral fellow an infectious disease expert myemma gender. Who's now faculty at Boston? Children's Hospital and Harvard Medical School. We had been looking at news media data. Cdc Data Electronic Health data. To understand the generalize ability of these data sources for both infectious disease and chronic disease. And now this become a very relevant the virus pandemic we had one of the conditions we've been studying was was flu like illnesses and understanding what electronic health data sources like billing claims an electronic health records what we can really understand from these data sources and we've seen people many people now start modeling making projections about cases and a death. Count's what we're going to start seeing next. Once people start. Having access to different types of electronic health resources is trying to use this data understand. You know to predict outcomes maybe to predict clinical courses were trying to causal inference which is even more difficult And it's very important that people understand the limitations of these data sources and so that's one of the things that we're working on and hopefully the the first paper from that work will be able to release in the next coming weeks but this is this is something that's relevant for the virus pandemic but has been a problem going back. Decades is using data. That people don't understand and that's been a at the forefront of my work is really making sure especially with the theme of one of the themes of this podcast machine learning a lot of people get very excited about machine learning and they throw a tool at data without understanding the data. And we're now in the midst of something where it's really crucial. That people do not do
How Long Can the Coronavirus Last on Surfaces?
"Let's talk about how long viruses can live on surfaces because between all those door handles credit card keypads and even our own cell phones we interact with so many services daily. I mean even if you don't hand your phone over to everyone you meet. You probably put down on say a table that other people have touched. And that's a fact of life but some of what we colloquially called germs that is viruses bacteria and other microbes that can cause infections and our bodies. Some germs can survive on surfaces outside of our bodies long enough to spread from one person to another. There's unfortunately no hard and fast rule for how long viruses in general can live on surfaces part of the uncertainties because viruses are diverse and have variety of surface survival rates the type of surface and environmental temperature and humidity. All come into play too so which surfaces are safe to touch. And how often do we need to disinfect? Them but wait. Let's back up a step what are viruses and are they even alive in the first place things that we generally considered to be living have more or less standalone ability to eat grow and reproduce a single cell. Bacteria or fungi. Or even sell from your body can do all those things because they contain the genetic instructions to do so plus the enzymes to carry out those instructions but viruses. Don't they have the genetic instructions DNA or RNA? But they don't have the right enzymes to create the chemical reactions necessary for reproduction. Instead viruses need a host cell which can be bacteria fungi or a plant or animal including a human a virus will attack a host cell and released its genetic instructions which hijacked the host cell's enzymes to make new viruses. That's good for the virus but generally bad for the host without a host cell virus can't survive long term however it does have a short window of time during which it can stay functional in hopes of infecting a new host and attaching to a host cell. Outside of a host viruses can either stay intact and remain infectious or they can degrade to the point that they're merely identifiable which means that you'll still be able to identify them from their genetic material but they won't be capable of seeking out an attacking host cells at the point that a virus on a surface is only identifiable. It won't be able to cause harm. The length of time that viruses can remain infectious on surfaces varies greatly there are baseline differences between viruses for example Rhino viruses. The viruses that are mostly responsible for the common cold will last for less than an hour on surfaces others such as norovirus which is a virus that can cause vomiting and diarrhea can last for weeks. Which is why. Norovirus can easily spread both through infected people and through contaminated foods and surfaces. There are several types of corona viruses. Most cause mild symptoms and are responsible along with rhinovirus is for the common cold but three types are known for causing more serious diseases. Moore's SARS and cove nineteen and because the corona virus that causes cove in nineteen is novel. The research into how long it can last on surfaces is new and ongoing a study published online on March Thirteenth of two thousand twenty by researchers at the National Institutes of health the US Centers for Disease Control and prevention and multiple universities compared the novel corona virus with the Corona virus that causes severe acute respiratory syndrome. Or SARS this is the most closely related. Human Corona virus to cove in nineteen and was responsible for the two thousand three epidemic. This study which has not been peer reviewed as of this recording found that the two viruses have similar viability in the environment which is to say not a whole whole lot. Something between rhinovirus and norovirus. The study determined that novel Corona Virus Can remain infectious for up to three days on stainless steel and plastic surfaces but survival on other surfaces was lower just one day on cardboard and four hours on copper and it was lowest at all in the air just up to three hours but keep in mind. Numbers are the maximum for the viability of the virus viruses. Start to degrade pretty immediately. When they're not an host the longer they're in the air or on a surface exponentially fewer of them will remain infectious. And if your immune system is working okay a lot of individual viruses need to get into your body either via your bucase membranes like your eyes nose mouth or via cuts in your skin in order for you to get infected. That's why direct person to person contact stilled easiest way for Corona virus to spread. And why everyone's telling you to wash your hands before touching your face. It's also why we don't have more precise numbers for how long corona virus or any virus for that matter. No matter how long they've been studied can last on surfaces. We spoke by email with Dr Alicia. Cray post doctoral fellow in epidemiology at emory university she said generally survival of pathogens on FEMME LIGHTS. Which are objects or materials likely to carry? Infection is determined by inoculating a surface with a known quantity virus and then sampling at various time intervals to determine the amount recovered. Scientists uses information to estimate a decay curve for the pathogen on the particular surface which can be extrapolated to longer time intervals the NIH and CDC team that studied surface variation for corona virus is still researching. They're looking into corona virus viability from snot versus phlegm versus poop as well as in varying environmental conditions because although viruses have differing baseline rates of survival on surfaces additional factors affect their ability to endure outside of a host like temperature humidity and properties of the surface itself. Cray said in general viruses survived longest at lower temperatures higher humidity and on non porous surfaces like stainless steel. However some viruses do well at low humidity. There have been a lot of theories about whether corona virus will lessen during warmer months because dry cold air like in the winter tends to provide favorable conditions for flu transmission. But we simply don't know yet. Dr Anthony Fosse Director of the National Institute of Allergy and Infectious Diseases explained during the March Thirteenth Twenty twenty CNN facebook global corona virus. Townhall that when considering the viability of a virus on various substances it's probably measured in a couple of hours while he recommends wiping down surfaces like doorknobs and cell phone screens. When you can. He cautioned against worrying about things like money and mail and the end despite the differences in viability on surfaces among pathogens fo- MITES and contexts. The number one recommendation for preventing the spread of viruses is standard. If you've touched a shared surface wash your hands before you touch your face or any part of your body that might have a cut or other skin abrasion. The human skin is great. If keeping out cold and flu viruses a thanks to its PH porous nature. They survived for only about twenty minutes on our hands.
Jake Goldenfein on Google Scholar
"Our guest today is Jack Golden Fine. He's a post doctoral fellow slow at the digital life initiative and he's originally from Melbourne Australia. He's research looks law in Computational Society including including the impact of platforms on user behavior. He's most recent piece of research. Looks at Google scholar. A relatively new free web search engine that indexes scholarly work in which has quickly become central to academic life just like other Google services have in other disciplines. I sat down with him just before the holidays and I began by asking him to explain what Google scholar is for the non scholars among us. And why it's become so important Horton. In recent years Google Scola emerged in two thousand and full when it was first launched it was just an academic search. Such engines are just like Google that ordinary such engine accepted return. Scholarly results how it defines something as scholarly has always been a little a bit vague. And maybe we'll talk more about why the Vagary of that is a bit problematic but the idea was it would return results that were relevant for scholars. Looking King Faculty make work since then. It's had a few more features added that perhaps beyond set actually more important or have had a bigger effect on the academic field in two thousand and six you able to stop saying citation counts associated with particular scholarly documents and then three years later. Two two thousand eleven google Google scholar launched sort of citation platform and what they did was give each racer. A profile like scholar profile filed outlined oleo publications and the citation counts of those publications calculations of academic quality or the quality of eraser. Sure premised on the amount of citations their publications getting over particular number of us. Silly amount the number of times other researchers will quote from your research search in their own research. Exactly it's the number of times that An article a document that you ride is referred to by other researches. It's pretty new right. You said it it started in two thousand and four so less than I mean a little over ten years. How how big is it now in the field? It do every researchers look at it when they're working on a new topic or so I would say. Almost every researcher would be familiar with it when Dougal scholars such sort of emerged on the sane librarians. This who Training young racers will always telling them be very wary of this because we sort of don't understand how it works as well as we understand. How other academic search search engines wet? It's also interesting. Because most academic search engines are quite disciplinary specific and they all they return results to a particular the corpus or repertoire of journals whereas Google scholar is disciplined agnostic a returns results across disciplines irritations results from academic journals but also other kinds of publications and whereas in traditional academic search engines. You have quite a lot of control over. What what you're searching for in Google scholar you have relatively limited control you can you can constrain the dates? But that's kind of more or less it. So it's always occupied had a bit of a funny position in research toolkit but it's increasingly a used because we're getting a lot more sort of disciplinary environments where people are interested in finding out information outside of their discipline and so google scholar becomes sort of fest port of coal in that kind of instance. But the thing that we're finding is maybe the big use of Google scholar is it's it's citation counting function it's bibliometric function on because what Google Scuola represents his really the easiest way to say. How many citations a particular research has received how come like what? Where did you get those metrics before? and and why were they less easy to find. People who are metrics have been around for a long time in the fifties those information scientists named using Garfield field. Who developed this process of citation analysis? Way You could effectively automate the organization. That is the indexing of scholarly work Iraq by its references so libraries with struggling with how to organize exploding amount of scientific and scholarly literature. And they will. Also you're thinking about how to to use computers to do that. The problem with during that is the sort of need to figure out a way to define the subject matter of of a publication in a way that a computer can understand and Eugene Garfield came up with a really clever way of doing that which is to look at references. Organiz it by the references rather than the actual actual content. This idea was really successful. It was really useful research tool but it also became clear quite early on that counting. Citations could give you a really Sort of rough guide to the quality of work because it gave you a measure of its reception in the field. It didn't tell you how people were trading but a told you people were rating in had some some sort of visibility. So through the sixties and seventies this eventually turned into a commercial product and in the nineties that was purchased by Thomson Reuters Webb of science over the last couple of decades has been probably the primary tool to get metric information but it's number one. The product was General Impact Factor in journal impact factor measured the number of citations to articles in particular journal. Over set a number of years. This citation analysis was used primarily for evaluating the quality of channels rather than the quality of individual researches now individual researchers started added to organize their own sort of scholarly prestige around the prestigious journal. Yeah so if you publish a nature medicine for example for a doctor it's not the same mm-hmm as in a local journal. That might be great but less has left citations nationally. Exactly so what we see during the seventies eighties nineties his citation starting to do lots of interesting things. We started to see journals effectively set their price according to the number of citations that were getting individual scholars. Who now were in this more competitive scully? Well because you know in the second half of the twentieth century the number of scholars in Christ raced dramatically along with massive increases in funding to. There's a lot more research is. There's a lot more research. Things are getting more competitive. The Prestige of your journal Becomes go away to sort of define your position in a market
"doctoral fellow" Discussed on Brain Science with Ginger Campbell, MD: Neuroscience for Everyone
"But would you mind starting out by telling us a little bit about yourself? Sure. Yes. So I studied psychology is an undergraduate though was also very interested in philosophy. And then went to graduate school in experimental psychology at university of Illinois in graduate school. I was mostly interested in studying how people learn new skills and habits than when I finished my in nineteen ninety five I've moved to Stanford to become a post doctoral fellow there that was right around the time that functional MRI which is the brain imaging techniques that I write about in the book was sort of becoming a prominent it'd been. Invented around nineteen ninety two. And so only a few centers were doing at Stanford was one of them, and I didn't actually go there with the intention of doing functional Mariah research, but I kind of got sucked into it. And so ended up spending four years there as opposed dog since then moved on and had several faculty positions. I was Harvard Medical School minute UCLA, and then at university of Texas and about five years ago, moved back to Stanford my interest in neuro science researcher, primarily around how it is that we make decisions and choices and particularly how we exert control over those choices consort grew out of my interest in habits because habits are so hard to control some of the work that we're doing is really trying to understand your what's the nature of self control. What are the brain systems that are involved in different aspects of self control? And then we also have some sort of basic science interest in what we call brain connectivity. Basically, how different parts of the brain communicate with one another in people what we can learn about that from brain. Imaging and how that connectivity changes over time. My lab also has a number people working on tools and methods to help people improve their nurses research..

"So now, yes. How do you? How does one do this for a living? Like who who'd employs you? So right now. Yeah, I work for the government of Canada a post doctoral fellow which is a way of saying that I'm kind of a late stage. Intern is the last way to do it. So I'm qualified to be a research. Scientists and qualified to do the science that I do, but I don't have my own lab. I don't have my own space yet to work out of. So I still work with mentors who have that lab space who have a little bit more expertise than me and more experience working in the field. So they're still teaching me things, but it's usually in a different manner. So now, they're teaching me how to get funding teaching me how to manage the lab how to manage students because you have to train PHD students master students and people they're gonna be the next generation of scientists. So a lot of my training now is not necessarily just about learning. You know, how these contaminants behave in bears it's about how to manage lab. And how to how to be more effective scientists too. So. We also a lot of the lot of the work is done through the government in Canada. And that's why we are able to do a lot of the things we do because we prioritize it funding for a lot of Alaskan research, for example. Now, there is some money from from the US government. But a lot of it comes from different sources. So the academics universities there, get the my themselves. And then they team with us often. And we do research over in Alaska and the same thing can happens in Russia because sometimes we can get money to do research over there to compare with ours. Even though it's not our country. So again, there's a lot of. I don't know. I guess a lot of disproportionate work that goes on. But it's okay because we're really trying to again cover off the much as we can. And and and you know, do much work with the end not just for interest. But again for the people live up there too. And you mentioned start the show that I've been trying to get on. And you were told me off the air that you'd switch jobs. So you working for a new employer? You'll have a new assignment or what's it looking like? Yeah. So right now, again, I'm a front line kind of research. Again, we get like polar bear fat Liber muscles ampoules. We process them in the lab a measure a lot of contaminants in the myla measure also measured things they tell me about what that polar bears eating. I can I can track back. The age again, the diet of the animal, and then relate that the contaminant concentrations on a day-to-day basis. So we're gonna write papers I participated what we call the primary literature. That's like again, you're rewriting scientific journal articles that are going out there with the first reports data. So we find a new contaminant and a polar bear we read about it. And it becomes a journal article. The new job is more of a will be more of an overseeing kind of -sition where I'm still heavily involved in a lot of the research in the Arctic. But thought he really management job is still being environmental science job. But it's would mean that I'm working with all different researchers studying everything from fish in plankton. All the way up to pull the bears across the entire Canadian Arctic in helping them coordinate their work with communities they work in. And then making sure that data is put into the databases where we can use it for bigger kind of approaches the problems, so knowing for example, like the one contaminant is building up in one small food chain around the Hudson vein blueberries is interesting, but we also want to know what the bigger picture of all the polar bears in candidate. Is this new job kinda give me an opportunity to explore those bigger picture questions? But I will no longer be in the frontline scientists again like processing that liver sampler that fat sample in the lab. So yeah, it's a really cool opportunity. And it just so happens that again certain positions of opened up at the right time..

"I'm Robin young. It's here and now how do death babies? Learn the thinking has always been infants overcompensate for their lack of hearing skills with increased visual skills. But that may not be true. A new study from the Ohio State University finds that deaf babies take longer to process visual stimuli than hearing babies and it happens early. Dr Clermont, ROY is a post doctoral fellow of auto Laron. Golly. Gee, that's the study of ear nose in throat at the Ohio State university's Wexner medical center. She's also the co author of the study, Dr monroy, welcome. Thank you. This isn't a negative finding this is just a new and different finding what is the finding. So what we found is that young infants in the first year of life who are deaf take longer to habituate to visual stimuli has no auditory component at all. It takes them longer to process and encode information. That's. Purely visual. Yeah. So you did what you had babies looking at a screen at images. Yeah. So we had a little baby sitting on their parents lap, and they would look at a novel objects. So just an animated completely made up thing that looked something kind of like, and then when babies get bored with something when they've looked at it long enough that they've encoded everything there is to encode they will look away we then will get their attention back and show them the same again, and we continue to do this until their rate of decline in how long they're willing to look reaches a certain threshold in the not amount of time is what we call the habituation criterion. Right. And you found that deaf. Infants were looking longer could it be that they're just more curious that's one possibility that's actually part of an ongoing debate. And we did take a close look at the data and see whether it could be the case. But all of our our analyses all converge in showing. They really seem to be taking longer most likely because they're processing this information more. Slowly, do I understand that children with hearing loss? They will learn simple words cat, five far sooner than abstract words. Go things like that. But does that even out over time? So that's complicated. For deaf babies. They're kind of trajectory of language development is very different. And it also really depends on so many factors fun. How long the period of deafness before they got some kind of access to sound like from a hearing aid or cookware implant, and what kind of input that they get from their parents and from the environment. That's one of the challenges is understanding all of that variability, and how that has implications for how they're going to learn. And when what else would you say to parents mean, I'll give infants time with things, but how else would they or doctors or teachers use what you've learned? I think that this particular research study really opens up more questions than it necessarily answers. So I it's kind of a starting point where we found this this new evidence showing differences in cognitive development from early infancy was something that you know, we didn't know before. And so what are the underlying mechanisms driving those differences? And what does that mean for future research? That's Dr Clermont, ROY co author of a recent study on deaf children in their ability to learn she's also a post doctoral fellow of auto Laron Galeotti study of ear nose and throat at the Ohio State University.

"Because every story has a flip side now beach sand go to the beach you know it comes and it goes it's literally washed away by tides and win sometimes faster than the waves can pilot backup so it is common for coastal engineers to try to replace the lost sand with sand scraped from offshore elsewhere where though sand gets deposited it's a process cold nourishment but does a work study appearing in the journal coastal engineering asked this very question looking at four beaches in california and while the researchers found that beach nourishment has helped keep some california beaches sand filled in the face of some challenging times there are some downsides to bunny look is a post doctoral fellow at the scripts oceanographic institute at uc san diego will come to science friday i had to be here thanks for having me your welcome so what are we learning you for sure about the benefits of adding sand to beaches yeah we'll the story just changes depending on what nourishment you're looking at but the few that we studied here in southern california there were some that were built with larger than native sand grains and those maintained relatively wide beaches for many years even during a big wave el nino winter so they they helped protect the the back beach from rozhin erosion and flooding from wave overtopping and promoted tourism so it really depends on the size of the sand grain was crucial yes we compared that behavior to nourishment that was built with sand with native grain sizes which washed off shore in one moderate storm months after it was placed that said the that sand was stored in a large offshore bar and some of it return to the beach the following summer but if you're trying to make the beach wider than the coarser grains were more successful in some sense when we talk about nourishing i love that phrase nourishing beach.

"Cartels all the corrupt government officials and the police can't even get police anymore because they're all if you're if you're a good person you joined the police you end up debt there's a piece out from the i think this was the frederick news post as an associated press piece originally i think far more us teens than previously thought ardour transgender or identify themselves using other nontraditional gender terms with many rejecting the idea that girl and boy are the only options new research suggests where do you think they get that idea just came to him forty or do you think they all television navy all are school school school lectures gender neutral policies that are cancelling dances i can tell you growing up in glastonbury connecticut i'd never heard of transgender never heard of it at all never once heard of it never knew anybody who thought they were transgender and now all these years later we're told that everything's everything's normal everything's a same no difference there's not two genders and dan the culture reinforces that idea the kids then get it in their minds and so uh young young man who was creative or you know likes you know likes design has suddenly a will maybe i'm transgender i don't know if that happens or not but i think it's really interesting that we have reporting that indicates that more young people are describing themselves as non gender conforming divers gender identities are more prevalent than people would expect said the lead author of the study a university of minnesota post doctoral fellow who studies transgender health that's a really narrow field of study yeah okay the study looked at students and ninth and eleven th grade an estimated that nearly three percent are transgender or gender nonconforming meaning they don't always self identify as the sex they were assigned at birth that includes kids who referred to themselves using neutral pronouns like them instead of he or she where.
