We interviewed Dr. Catalina Cuellar-Gempeler, a professor of microbial ecology at Cal Poly Humboldt about her work on microbial community ecology on pitcher plants

The California academy of sciences is one of California's oldest operating museums and research institutions. It is an invaluable repository of knowledge about the natural sciences, is home to 47 million specimens, and has hundreds of thousands of visitors per year. This week, on Radiobio, we had the privilege of speaking with Dr. Shannon Bennett, the chief and dean of sciences at the Academy. She gave us all the behind the scenes scoop about the academy of sciences, as well as her own fascinating path into science. This is Radiobio!

We've all heard of COVID-19, saw its impact on society, and probably even faced the respiratory illness itself. But is there… math behind this disease? And if so, can we use math to help fight COVID and other infectious diseases? It turns out that our collective behavior during outbreaks can mathematically fuel models of public health. Join us as we explore the fascinating world of mathematical biology. This is RadioBio.

Imagine you are at a hot springs. The water is boiling and bubbling, there's the smell of sulfur and other acrid chemicals in the air, and it is unbelievably hot. Is it possible that life can exist in these unforgiving conditions? It turns out yes! There are microbes, called thermophiles, that not only just exist in these conditions, but have adapted very particular ways of thriving in what are some of the most unforgiving conditions on our planet. This week, we talk to Dr. Ruben Michael Ceballos about these fascinating organisms. This is Radiobio!

There are plenty of fish in the sea… this week, we take that saying to a whole new level! Fish are incredibly diverse and their life cycle is complex; this week on Radiobio we talk with Dr. Chrissy Hernandez about her research on fish population dynamics. Dr. Hernandez applies math to complicated ecosystem level questions, with fascinating results. This is Radiobio!

Nature versus nurture, the eternal question. We usually think of our genes as permanent, a part of our nature, something that is passed down to us and that's it. But how much of our genes change as a results of our actions today? How much do our genes change because of what we have been eating for the past 10 years? Turns out, behaviors and the environment can actually change our gene expression! We delve into some of these factors with our fabulous guest this week, Dr. Monica Dus, a professor of neuroepigenetics at the University of Michigan. This is Radiobio!

We live in a microbial world. From our own gut to the corals in the ocean, microbes are key players in the existence of so many organisms. Did you know that corals are not just single organisms, but exist in symbiosis with millions of single celled algae? This symbiosis is currently threatened by global warming and climate change, resulting in a process you may be familiar with, called coral bleaching. This week, we spoke with Dr. Viriginia Weis about her timely and fascinating research on the topic of symbiosis between corals and algae. INSITE Vision: Inspire an inclusive and diverse interdisciplinary community of scientists for the conservation of biological diversity and public education in a changing world. INSITE Mission: Create novel tools to better conserve biological diversity under threat of climate change through cutting-edge research, scientific training, and public education.

Life finds a way. Even in the face of incredible pressure from other organisms, climate change, and pollution, species still find ways of persisting. Sometimes this pressure is too much, and populations go extinct. Why are some species able to survive, and others able to persist? How much pressure is too much pressure? And can species find ways to survive through their interactions with other species? We dive into all of these pressing questions and more with our guest this week, Dr. Diane Campbell, a distinguished professor from the University of California - Irvine. This is Radiobio!

Imagine you're a squid, yeah okay its weird but just imagine it, you are a squid swimming at night. It's a dark night except for the light from the moon, and there is a predator roaming around looking for its dinner. Now imagine you are a squid who can camouflage yourself to match the light from the moon and the stars so your shadow disappears. You trick the predator while you go on your way looking for your own dinner. Seems kind of magical right? Well that's exactly what bobtail squids do, except they get help from their bacterial friends. Today on RadioBio we talk with Dr. Michelle Nishiguichi, a professor at the University of California, Merced about glowing squids and their symbiotic sidekicks.

We are still discovering the mysteries of the brain and one way to do that is to use tools such as computers. On this episodes of RadioBio, we speak with Dr. Kanaka Rajan, a computational neuroscientists at the Icahn School of Medicine at Mount Sinai.

Have you ever thought about the soil beneath your feet? Let's take it one step further... have you ever thought about everything that lives in the soil beneath your feet? Well, prepare yourself, because this week we interview Dr. Lauren Hale, a researcher from the US Department of Agriculture, the USDA,  about her research on the soil microbiome. Dr. Hale talks about soil health, nutrient cycling, and the cutting edge of  research on the microbial world living underneath our feet. This is Radiobio!

Ants, they are everywhere if you look for them! Ants engage in all the things that we associate with our own society, like farming and policing, and have complex social structures. This week on Radiobio, we talk to Dr. Ehab Abouheif, a professor from McGill University, about his research on cooperation in ants and the microbes that exist in symbiosis with them. This is RadioBio. link to nature paper:  https://doi.org/10.1038/s41586-020-2653-6 link to deborah gordon: https://soundcloud.com/user-386034408/radiobio-interviews-dr-deborah-gordon?si=49cba8aa279942e9beec58588e983a24&utm_source=clipboard&utm_medium=text&utm_campaign=social_sharing

This week on RadioBio, we explore insect wings. Did you know insect wings are more than just beautiful appendages? They are a part of an amazing circulatory network. We discuss the biomechanics of insect wings and what makes them so amazing with Dr. Mary Salcedo, a postdoc at Virginia Tech. Link to Dr. Salcedo's Review: https://doi.org/10.1093/icb/icaa124 Link to Dr. Salcedo's Website: https://www.maryksalcedo.com

What if I were to tell you that you had hundreds, if not thousands of microbes living on you hands, you would probably respond with ewwwwww...gross and immediately want to sanitize or wash our hands. If I were to tell you that not all of them are bad, but rather most of them are good, you might still be skeptical. Let's take it one step further. What if I told you that we can use naturally occurring bacteria as a form of pest control. Wild right! One of these bacteria is Wolbachia. Wolbachia affects the reproductive system in certain insects and can make them sterile. The cool part is that Wolbachia do not affect humans or other large invertebrates, but it does infect many insects that we classify as pests. Today we explore the world of Wolbachia and learn about how these little bacteria can kick some insect pest butt with Dr. Amelia Lindsay......This is RadioBio!

Bats are vital for maintaining balance in the ecosystems they are a part of: Bats keep insect populations in check, pollinate flowers, and disperse seeds. Bats are also an incredibly diverse group of species that come in all shapes and sizes! Did you know, that if you randomly picked a mammal, you would have a one in five chance of picking a bat? Today we have Dr. Alexa Sadier with us to talk about what studying bats can teach us about evolution.

Imagine the world 430,000 years ago. What were our ancestors like? What if there was a population of people that no one ever knew about? Can we unravel the mystery of our history? Now imagine, your garden at home is full of aphids. Did you go buy some ladybugs at your local home depot? Have you ever thought where those ladybugs came from or what happens after they leave? Now these two situations may seem very different but they have one common theme. They both have questions that can be studied using population genomics. This week on RadioBio we talk about popgen, ancient humans, ladybugs and ghost populations (ooo spooky!) with Dr. Arun Sethuraman, an assistant professor at San Diego State University.

Throughout this historic pandemic, there have been many changes to our social and work environments that have been far from our baseline. Work from home, has led to greater isolation and less ability to socialize with our coworkers and friends. This has undoubtedly affected the mental health of people all over the world, and this topic came up during chapter 4 of our COVID interview series, when Dr. Allen spoke about the mental health crisis emerging in Mariposa due to the stress of this pandemic. This inspired us to reach out to a mental health professional, specifically Dr. Tania Gonzalez, our very own director for Counseling and Psychological Services (or CAPS) at UC Merced. In this interview, we delve into the mental health impacts of this pandemic on undergraduate and graduate students at UC Merced, and the importance of maintaining laughter and routine as we come out of this experience. This is chapter 5 of our COVID interview series, in which we interview a series of professionals on different topics related to the pandemic. This is our final chapter in this release series, and we hope you have enjoyed hearing from many perspectives to gain greater context for what we have all been experiencing this past year.

All over the news, we hear about drug development and vaccines, masks wearing, and being in a red or purple tier,  but have you considered how this is affecting communities, maybe your community? In this interview with Dr. Kristina Allen, Deputy Director of Public Health from Mariposa county, we discussed coordinated response to the COVID-19 outbreak as well as the mental state of communities that have been affected by COVID-19, and how local governments and rural areas are fighting to keep their community alive. This is chapter 4 of our COVID interview series, in which we interview a series of professionals on different topics related to the pandemic. Tune in for our next chapter, an interview with Dr. Tania Gonzalez, the director for counseling and psychological services (CAPS) at UC Merced , on her experiences with the pandemic!

COVID 19 has changed so many things about the world we live in, but few things have changed as much as our perceptions of public health and its role in our modern society. How has the US reacted to COVID 19, and what things could we have done better? What if our social services and health services could be better integrated? How does testing and contact tracing actually happen to monitor the transmission of coronavirus? Today, we answer all of these questions and more by talking with Dr. Zweifler, a medical consultant from the Fresno County Health Department. This is chapter 3 of our COVID interview series, in which we interview a series of professionals on different topics related to the pandemic. Tune in for our next chapter, an interview with Dr. Kristina Allen, Deputy Director of Public Health with Mariposa county, on her experiences with the pandemic!

This past year, we have been in the midst of a historical pandemic that has touched the lives of everyone around us. As part of our interview series on COVID-19, our team was interested in gaining the perspective of a medical doctor and how this pandemic has affected healthcare workers. For this episode, we interviewed Dr. Xavier Gaeta, a doctor currently in pediatric residency in a LA county, as well as a PhD. Dr. Gaeta gave us invaluable perspective on being a doctor during the pandemic and insight into the differential impacts of COVID on children versus adults. This is chapter 2 of our COVID interview series, in which we interview a series of professionals on different topics related to the pandemic. Tune in for our next chapter, an interview with Dr. John Zweifler, a medical consultant with the Fresno county Health Department, on his experiences with the pandemic!

Vaccines and drugs to mitigate sickness have become a central part of modern life, and they have become a central topic right now as the COVID 19 pandemic has progressed. But how are vaccines developed? What is the difference between a vaccine and therapeutic drugs? And could we actually one day treat coronavirus with a pill? Today, we talk to Dr. Robert Davey, a professor of microbiology from Boston University, who is currently working on ways to find treatments for dangerous viruses. This is chapter 1 of our COVID interview series, in which we interview a series of professionals on different topics related to the pandemic. Tune in for our next chapter, an interview with Dr. Gaeta, a pediatric resident, on his experiences with the pandemic!

It can be hard to make decisions, but do you know that your cells makes decisions too? What is even more amazing is that we can actually watch cells do this. This week we discuss cells and how they communicate and understand each other with Dr. Orion Weiner from the UCSF Cardiovascular Research Institute.

Have you ever wondered what's the difference between a bug and an insect? Are spiders even an insect? Wait are lobsters and crabs related to bugs? Why do we even care about these insects and parasites? Well, we all know that bees are important for our food because they pollinate many of our plants that produce food for us, but insects have lead to many other discoveries. Did you know that many human genes that have been shaped by Darwinian evolution are genes that are involved with dealing with viruses and large parasites? Crazy right? Well today, we dive into Dr. Whiteman's work that follows Darwin and Wallace discoveries which is focused on evolution of new traits that are shaped though interactions between organisms.   This is Radio Bio!

Have you ever wondered why pregnant women shouldn't change the litter box? How about why your meat should always be well cooked? Well, one of those reasons is Toxoplasma gondii. Over 2 billion people are infected with this brain parasite. However, our understanding of the effects of Toxoplasma on humans, especially on their brain are small. Almost as small as the parasite itself. This week on RadioBio, we discuss who gets this parasite, what we can do to prevent or treat it and an introduction into the research taking place to discover the role of this parasite in the body with Dr. Rema McLeod from the University of Chicago. This is RadioBio.

Humans might be the worlds greatest evolutionary force. From pollution to deforestation, human induced changes have a huge impact on the environment around us. But how are animals adapting to the changes in their environment? This week on RadioBio, we talk with Dr. Rachel Bay from the University of California, Davis about her work investigating evolutionary genomics in an ever-changing world.

Achoo! Ah, allergies, the first sign of spring or also a sign that the barista accidentally did make your coffee with whole milk instead of soy. But what is your body doing during an immune response? Particularly, an allergy immune response. And why are your cells causing you so much misery? Well, join us this week as we dive into the fascinating roles that our immune system plays during allergic responses with Dr. Richard Locksley.

DNA is all over the place. It sheds from everything, everywhere, throughout time. What if you could just scoop it up and figure out what it is... well, we can! Environmental DNA, or eDNA, is DNA that's left over in the environment and is an important tool we can use to understand life as we know it. This week on RadioBio, we talk with Dr. Rachel Meyer from UC Santa Cruz all about eDNA-- how you collect it and what you can do with it, and even how you can get involved. This is RadioBio.

Spring and Fall are often accompanied by a chorus of sneezes-- allergies are the bane of this beautiful time! Allergies, our immune system’s response to foreign substances, can be more than uncomfortable-- long term exposure to allergens can be linked to chronic pain. This week on RadioBio We talk with Dr. Devavani Chatterjea from McAlaster College about her work investigating the link between allergies and chronic pain.

Ever wonder what it takes for a forest to regenerate after a devastating wildfire? Turns out microscopic fungi in soils play a big role in that recovery. These fungi partner up with all kinds of plants, helping out in many environments and industries, from helping crops to flourish to restoring plant biodiversity. Join us as we discuss these topics and more with Dr. Sydney Glassman. This is RadioBio.

From gummy bears to cars we learn the importance of adhesion and lubricants for everyday life. Whether you're a muscle on a rock trying to hold on during high tide, or you're a runner and relying on the lubricants to keep your knees moving. The research that is conducted to understand these phenomenon can help us fix issues in health care that many of us suffer from, such as arthritis or joint damage from injuries. Today, we will explore the concepts of adhesion and lubricants that are all around us with this weeks guest  Dr. R. A. Eguiluz. This is Radio Bio!

The immune system is complex, full of lairs of communication and strict regulation, all to keep us healthy and alive. But what happens when those checkpoints break down? In this weeks episode, we learn about how B-cells can turn against us and what that means. We talk to Dr. Roberta Polenda from University Colorado, Denver about her research on this subject.

Have you ever thought about brains? Our brains are seriously important, that's not news, but how do they actually work? There is a delicate balance between order and chaos. RadioBio this week is all about stability in the brain. Hopefully by the end you'll know a little bit more about how your brain works!

CRISPR. You may have heard about it in the news. It's arguably the biggest discovery of the 21st century, and could possibly be a cure for some of the genetic disorders that have plagued humans throughout our history. It was initially identified in the early 1990s and more recently it was discovered to be the immune system used by bacteria to fight off viral infections. Until recently there were no known mechanism for inhibiting the infections caused by these bacteria-infecting viruses. Dr. Joe Bondy-Denomy is a leader in the CRISPR field and discovered anti-CRISPRS, the system used by viruses to hide out from the bacterial CRISPR system. We talk with him about his discoveries in the field and the ethics of gene editing in humans.

Have you ever been curious about how our brains "learn" and why only somethings seem to "stick" and others seem to fade away as time goes on? I know I have. How are memories stored? Today we are going to explore the brain's amazing ability to learn and store information over a lifetime, as well as a recently discovered mechanism of neuronal communication that resembles the life-cycle of retroviruses.

You and I .... are completely different.... Not just because we like different music or have different parents, but because we are more than individuals. We contains multitudes of microbial communities and, believe it or not, my community is different than yours. Today, we are talking with Dr. Kathryn Milligan-Mhyre about her research into how microbes associate with hosts and how those microbes change over time

Do you grow your own food or butcher your own meat? Many of us don't. We get our food from a lot of different places in our modern society and we have a global network of food import and export. But what happens when there is contamination in our food supply? How do we know where the contamination is coming from when our food is coming from all over the place? Join us as we find out how we can use genomic data to explore this issue in this episode of RadioBio.

Have you ever thought about how weird hybrids actually are? Some hybrids seem to be a contradiction: they can't reproduce! How could nature allow this? Today we discuss the evolutionary conflict of speciation, hybrids, and sterility.

Have you ever thought about how light affects your behavior on a day to day basis? Now think about how light would affect you on a molecular scale? Molecules have a direct influence on behavior from sleep cycles to depression and motivation. Today we discuss molecules, how they affect animal behavior, and the origins of such an intimate relationship in molecular biology.

It's getting warmer and drier, but there may be an untapped natural resource that can offer fresh water: fog! Fog is more than just one way your beach day can be ruined-- Coastal fog has the potential to be a major contributor to future sustainable agricultural practices. Today we discuss fog and its impact on crops in California.

This week is a special edition of RadioBio, put on for UC Merced's International Education Week. In this episode, we hear from five different researchers and their unique experiences with international research: Dr. Asmeret Asefaw Berhe, Dr. Felipe Zapata, Dr. Gregory Mutumi, Dr. Samuel Wasser, and Dr. Teamrat Ghezzehei. From soil science to conservation biology to everything in between! Each story highlights the various ways we can be inspired by the world around us, and how science reaches beyond physical and political boundaries. Join us, as listening to life, goes international!

What is a virus? Why are they important? Viruses can cause disease and mortality, and they also significantly influence ecosystem ecology and environmental chemistry. Today we discuss viruses and their role in biogeochemical cycles and agricultural systems with Dr. Joanne Emerson from UC Davis.

Here's a riddle for you, what is something that stays behind in an environment after an animal is long gone? The answer is... POOP! What if we could use poop to study animals that would otherwise be difficult to track down? Well, Dr. Sam Wasser does just that. This week on Radiobio, we talk with Dr. Wasser from the University of Washington about how he uses poop to better understand animal populations with implications from tracking poachers to tracking whales.

Matter in a random universe. How does it behave? Can we predict it? When physics meets biology, this intersection between two disciplines can crack some major gaps in our understanding of how matter transforms from one state to another. Today we discuss proteins that change their physical state and the theory that goes into understanding this state change.

Water. It is one of the basic requirements of life as we know it, especially in California. The Washoe people of California's Sierra Nevada mountains believe that all water bodies contain water spirits known as water babies that dictate if you will catch fish or if the river will run dry. And these beliefs are founded in the reality of water's significance...the Sierra Nevada mountains are the reservoir of California, with more than 60% of the state's water originating in the mountains. Our history, our economy, our entire being is tied to how much water falls on these mountains. But what happens...when the water stops? Today, Kinsey Brock, Morgan Quail, and I, Jeff Lauder, speak with a hydrologist and three ecologists about what made the 2012-2016 drought so historic, and how studying its impacts on forest ecosystems can help us understand what a changing climate means for California.

How do you search for a virus? Even worst, how do you search for a virus's DNA? A virus you've never seen before and have no clue what it looks like! If you think of one of your cells as the size of a baseball stadium, a virus would about the size of a baseball. You could try a targeted approach by sequencing your best, educated guesses but with metagenomics you can sequence everything but the kitchen sink. This week we talk small viruses and big data with Dr. Eric Delwart.

Imagine a world with no leaders. No Presidents. No generals. No bosses. No central control. Ants have successfully occupied every continent on earth and even though they have a queen, they use a system with no central control which we term collective behavior. But what is collective behavior? How do we begin to understand behaviors that emerge in a spontaneous way? Dr. Deborah Gordon, Professor of biology at Stanford University, joined us to talk all about collective behavior in ants.

Have you ever wondered what powers us? We all consume food for energy, but HOW does that actually turn into energy?  You may be familiar with the molecule ATP, or adenosine triphosphate. ATP is used to store energy from the breakdown of food, and through a process called hydrolysis, that energy can be released and transferred to power reactions. This tiny but mighty molecule is what powers nearly every reaction in our cells. In this episode, we journey inside the cell as we learn more about this powerful molecule, and the specialized structure inside the cell where its made, the mitochondria.

"The thymus is a really ugly-looking organ, but tastes fantastic. Have you ever had sweet breads?" In case you don't know, sweetbread is the culinary term for the thymus, but what is the thymus, besides a tasty dish? In this episode Genevieve and Stephen sit down with Dr. Jarrod Dudakov and discuss what the thymus is, its function, and why it is worth researching.

When you are thinking about how the world works, how often do you think about the tiny forces of nature? Just about never, what do you mean? I mean microbes! They play an important role in ecosystem processes such as decomposition and nutrient cycling. But what do we know how these microbes live in nature? It turns out they live in communities, just like we humans do. In this episode we talk with Dr. Jennifer Martiny from UC Irvine about her work with microbial communities.
