Today we talk to Dr. Iswar Hariharan about his research studying the genetic regulation of growth and regeneration using fruit flies. Learn about how the same genes that control organ size during development are often the ones mutated in human cancers, and what this means for the future of regenerative medicine. This podcast was recorded in Spring 2023.

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!

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!

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.

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.

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!

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.

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!
