Sea urchins may have a spiny reputation, but they are vital members influencing kelp ecosystems. Join us as Delaney Chabot, a third-year Master Student in Integrative Biology, discusses their importance and also how they act as a connecting link between subtidal and intertidal zones. Delaney is a passionate educator and the visionary behind the 'kelp horn' - listen in to hear more! Hosted by Matt Vaughan and Taylor Azizeh.

Join us as we zoom into the "nano world" with Kelso Arthur, a third-year PhD student in Environmental and Molecular Toxicology at Oregon State University. In this episode we discuss nano and microplastic use in agricultural pesticides, what impacts they could have on environmental health, and how indicator species can help us assess their effects. Kelso shares their journey on how their roots in Kentucky helped pave their pathway into graduate school. Hosted by Matthew Vaughan and Esteban 'E' Hernandez. 

Mammals encompass some of the most interesting animals on the planet. We can see how bats have mastered the sky with wings like birds or how dolphins have adapted streamlined bodies for life in the ocean just like fish. The ability to evolve similar characteristics to overcome common problems found in the environment is called convergent evolution and opens our eyes to the fundamentals of how life has changed to face the challenges of our planet. One such trait that is the product of convergent evolution is echolocation, which is the subject of research for our guest on the show this week Serena Frazee.

If you walk into any grocery store today and find yourself in the beverage aisle, you’ll be able to find all sorts of “prebiotic” sodas touting ingredients like inulin that claim to improve gut health. Many of us are familiar with probiotics and the gut benefits of fermented or cultured foods that contain beneficial bacteria, but prebiotics are a little different. Prebiotics are typically nondigestible fiber compounds that pass undigested through the upper part of the gastrointestinal tract and function as a food source for your gut’s microorganisms.However, it is unclear what the effects of prebiotics are on the human gut microbiome, and more specifically, how diet influences these effects. This is exactly what Emilee Lance, second year PhD student in the department of microbiology, is aiming to understand. Under the guidance of PIs Ryan Mueller and Tom Sharpton, Emilee is working on understanding how the gut microbiome is affected by prebiotics like inulin, and the impact that diet can have on prebiotic efficacy. Using a gut simulator called a SHIME (The Simulator of the Human Intestinal Microbial Ecosystem) she is able to totally control the initial microbial environment, diet, and mimic specific regions of the gastrointestinal tract such as the stomach, small intestine and different colon regions.

Sometimes the smallest things in the universe can answer some of the largest questions. That seems to be the case with neutrinos. But what exactly are these fundamental particles, that also happen to be the most abundant in the universe, and why are they of importance? Listen in to hear Noah shed light on all things neutrinos, including undereground research facilities! Hosted by Matthew Vaughan and Taylor Azizeh.

Join us as we dive into the world of apex predators with shark researcher Jessica Schulte, a PhD candidate studying the foraging behavior and movement of broadnose sevengill sharks in the Pacific Northwest. This episode is packed with mystery, fun shark facts, unexpected diet discoveries, crazy field stories, and inspiring ventures that lead to a career working with sharks! Hosted by Matthew Vaughan and Taylor Azizeh.

For most of the time that biochemists have been studying proteins they have preached the widely adopted dogma that structure equals function. Proteins are macromolecules made of chains of amino acids, and as they are produced they fold into intricate and specific shapes. These shapes or ‘structures’ are critical to the tasks that they perform, like producing energy for the cell, carrying molecular cargo from one end of the cell to the other, or letting ions across the cell membrane. However, over 30% of the protein humans produce has no specific structure. These are called intrinsically disordered proteins, and only in the last 15 years have they been brought into the spotlight of biochemistry and biophysics research (Structural Disorder in Eukaryotes). Hannah Stuwe is a fourth-year PhD candidate in Biochemistry and Biophysics, and her research revolves around disordered proteins, particularly a protein from SARS-CoV-2 called the nucleocapsid protein. In her work she uses state-of-the-art techniques specifically suited for studying disordered proteins to understand how the flexibility of this protein changes throughout the viral replication cycle. 

Per- or Polyfluoroalkyl substances (PFAS) are a class of chemicals that are known for their ability to contaminate our environment and be resistant to breaking down. However, there’s still a lot to learn about their potential for toxicity. One way scientists can better understand PFAS toxicity is by using the embryonic zebrafish models. These tiny fish have a genome that is around 70% similar to humans. This makes the zebrafish a powerful tool in understanding how some chemicals may express toxicity in humans. Eli Cowan is a second-year PhD student in the lab of Robyn Tanguay, which is a part of the Environmental and Molecular Toxicology lab here at OSU. His research focuses on using the zebrafish model to understand how PFAS exposure may lead to adverse effects in development. With this data and using his in-dept knowledge of biology, Eli then can help answer questions about how PFAS may be toxic to people. Eli was raised in Vicksburg, Mississippi, where he first encountered zebrafish toxicology in a locally-based lab. Eli has always been a natural born scientist, and that curiosity has led him all the way across the country pushing the bounds of science.

If someone asked you to describe a shark, I imagine most folks would report a ten-foot long body, rows and rows of razor sharp teeth, and the ruthless nature of a (literal) cold-blooded killer. If you asked Master’s student Reilly Boyt to describe a shark, she would likely describe a salmon shark. Reilly is our guest on the show this week and she studies the diet and habitat use of salmon sharks using multi-chemical tracers (e.g. eDNA metabarcoding and fatty acid analysis) across size classes and sex. Reilly is also the founder and CEO of Disabilities Within Ocean Sciences (DWOS), an organization dedicated to “building a network and resource hub for disabled marine scientists at every career stage.” She has done prolific advocacy work that focuses on promoting inclusivity and equitable access within the field of marine science. Hosted by Taylor Azizeh & Lisa Hildebrand.

As global temperatures rise, ocean levels and extreme weather occurrences rise with it. One of the leading causes of global warming are greenhouse gases like CO2. Emily Hiatt's research is tryign to develop a cheap, robust way to capture CO2. This topic is hot; even hotter than the rising global temps.

What's cooler than land robots? Underwater robots (ice cold!), which Akshaya Agrawal's PhD research in the Robotics Department focuses on. Her research is indeed cool; developing and testing motion-planning algorithms designed to help teams of robots coordinate movement and perform tasks underwater. But have you ever wondered what's involved in getting robots to operate underwater? And how exactly does one get to work with underwater robots? Listen in to  find the answers to those budding questions, as well as Akshaya's journey from India to the U.S, ...or just to hear cool stuff about cool robots! 

If you’re not a fan of ‘The Office’ then that title probably made no sense to you. But, if you are, then you’ll know that Michael Scott famously said that mercury poisoning is one of the five Goliaths that America faces (though we never actually find out what the fifth one is…). Regardless, on this week's episode you’ll be able to learn all about this Goliath as our guest, the newly minted Dr. Cailin Sinclair, discusses his doctorate and post-doc work investigating mercury cycling in freshwater systems. Hosted by Lisa Hildebrand.

Emily Dziedzic, a PhD student in the Department of Fisheries, Wildlife & Conservation Sciences, is a molecular ecologist who focuses on bioinformatics, which means that she uses computer-based methods to analyze genetic data. Her work spans a wide variety of taxa, from freshwater fish to scarlet macaws, from bats to Humboldt marten, and has implications for improving ecological monitoring for management as well as assisting in the fight against wildlife disease. Hosted by Lisa Hildebrand and Mireia Roig-Paul.

This week on ID we are interviewing Mireia Roig-Paul, a second year PhD student in Environmental and Molecular Toxicology, to learn all about pollutants and the potential threats they pose to our environment and our health. She studies in the laboratories of both Jennifer Fields and Serhan Mermer, and her research focuses on the intersection of so-called “forever chemicals” PFAS and non-aqueous phase liquids (NAPL), how they move through soil, and how they interact with each other.

In the wake of the ongoing graduate employee strike at Oregon State University, Hannah and Mireia sit down to talk with the president and VP for Communications of the Coalition of Graduate Employees (the labor union that represents graduate employees at OSU). Austin Bosgraf and Erika Stewart explain the string of events that lead to this strike, what is at stake for vulnerable grads, and where we go from here.

Dams, climate change, habitat loss, predation, anglers. Wild salmon must contend with all of these challenges during some point in their lifetimes. But an additional challenge may be having a negative impact on wild salmon that we don’t yet quite understand: hatchery salmon. Investigating the impacts of hatchery salmon on wild salmon is no easy feat, and it’s not made easier when you’re trying to do it in possibly one of the most remote and wild places in Oregon…But that’s exactly what our guest this week is doing! Emily Treadway is a first year Master’s student advised by Dr. Seth White in the Department of Fisheries, Wildlife, and Conservation Sciences at OSU. On top of being a graduate student, Emily is also an employee at the Oregon Department of Fish and Wildlife working within the East Region Fish Research Office. Hosted by Lisa Hildebrand.

Taylor Azizeh, a first-year Ph.D. student at OSU’s Marine Mammal Institute, joins Matt to discuss how climate change might be driving gray whales to shift their feeding habits along the Pacific Northwest coast. Taylor's research explores the phenomenon of 'prey switching,' where these benthic specialists switch from seafloor to water-column feeding. By combining stable isotope analysis, GPS tracking, and drone photogrammetry, Taylor aims to understand how gray whales adapt to changing prey availability in a warming ocean. Listen in to hear about her journey from Costa Rica to London to OSU, her passion for these majestic animals, and the big-picture questions she seeks to answer. Hosted by Matthew Vaughan.
