RadioBio Interviews Dr. Julie Zikherman

5/22/2018
More
Autoimmune diseases occur when our immune systems start to attack our own cells, rather than foreign invaders. Unfortunately, very little is known about how these disorders arise in otherwise healthy individuals. Join us as we talk with B-cell immunologist and autoimmune clinician, Dr. Julie Zikherman, as we discuss how to control these inappropriate immune responses.

RadioBio Interviews Dr. Robert Phillips

Genetics is a majorly hot topic in biology right now -- everything is genome sequencing this, gene expression that -- but how much do we really know? We know a lot about which genes are present in which organisms, and what certain genes do, but not a lot about how or why they do it. Our guest today, Dr. Rob Philips, is a researcher at CalTech who is working to understand the language of gene regulation, and the methods we can use to understand how genes work.

Whenever you're sick, your immune system springs into action, but how? T-cells are like the generals of your immune system, and they command your immune system in battle against pathogens. Dr Rothenberg from @CalTech tells us all about this process and how these cells train into the powerful generals they are on this episode of RadioBio.

Dr. Heinrich Jasper shows us new tools using Stem Cells that can help with both our longevity as well as degenerative disease. The Jasper lab is focused on regulatory mechanisms that control stress tolerance, metabolism and aging with the help of fruit flies. In particular, Dr. Jasper has been recognized for making seminal discoveries about the effects of aging on stem cell behavior, and about the role of stress in regulating stem cell function. Current projects in his lab focus on the...

Two words: Flying Lizards. How'd it happen? Evolution. Evolutionary history is complicated. It can sometimes be helpful to look at funky animals to see what their unusual traits tell us about their history. For example, Dr. Jim McGuire from the University of California Berkley, studies the evolutionary correlates of size, color, and flight in lizards.

Viruses are iconically challenging to define, but they have DNA so they evolve. In the 1980s, the Human Immunodeficiency Virus (HIV) shook the world and propelled a massive undertaking to study the evolution of drug resistance in viruses. On world aids day, December 1st, 2017, we spoke with Dr. Pleuni Pennings from San Francisco State University about how viruses adapt to treatments through time.

RadioBio Interviews Dr. Adriana Briscoe

We may not think about it this way, but there is a whole world of colors that we can not perceive or understand that other organisms use on a daily basis, like butterflies. Did you know that even males and females from the same species see the world differently? Today on RadioBio, Dr. Adriana Briscoe discusses the evolution of color vision in Heliconius butterflies using genes, physiology, and behavior.

Have you or someone you know been affected by sleep disorders, depression, or even drug or alcohol addiction. Believe it or not this may be linked to how and when you sleep...which is actually controlled by when you eat. Dr. Joanna Chiu, Professor of Entomology at UC Davis, studies the animal circadian clock and its control on organismal physiology. Besides being indispensable for the control of daily activities, defects in circadian rhythms and clock genes have also been implicated in a...

If you've ever had a pet or known someone with a pet, you probably know what a round worm is, but did you know these are nematodes? 180 years of visualizing these fascinating worms gives us insight into biodiversity, evolution, and marine ecosystems. This week Dr. Holly Bik from the University of California, Riverside guides us through an exploration of these mysterious deep sea creatures using both ancient and novel techniques.

How do cells interact with their physical environment? Dr. Otger Campas from the University of California, Santa Barbara joins RadioBio to discuss the physical properties of cells and how the interactions between cells and their environment shape cell and organism development.

RadioBio Interviews Dr. Embriette Hyde

12/19/2017
More
You may have heard about the human microbiome or even the pro-biotic fad, but how much do you really know about the micro-organisms that live on and in you? Dr. Embriette Hyde from UC San Diego discusses her work with the American Gut Project on understanding the world of human microbiome. This work could lead to advances in our understanding of both the human health and human disease.

Have you ever wondered why males and females of a species are different sizes, shapes, and colors? Dr. Marie-Claire Chelini, University of California Presidential Post-doctoral Fellow, discusses her research on the evolution of sexual size dimorphism in crab spiders.

RadioBio interview Dr. Aaron Gitler

11/7/2017
More
How do misfolded proteins cause human neurodegenerative diseases, like Alzheimer's, ALS, and Parkinson's? The Gitler lab at Stanford University studies the cellular biology underlying protein-misfolding diseases using the model organism yeast. Since dealing with misfolded proteins is an evolutionary problem, they hypothesize that the mechanisms employed to cope with misfoldings is likely conserved from yeast to humans. Gitler's long-term goal is to identify the critical genes and cellular...

Evolution; no small topic. Biologists can use a diverse array of systems to try to test evolutionary concepts. Some systems, like bacteria, are useful for looking at how evolution happens in real time, because they have such short generation times. Others, like animals, are much more difficult, but can allow us to ask really interesting questions like how behavior influences evolutionary processes. Dr. Kathleen Ferris, asks questions about how organisms respond to stress in an evolutionary...

Climate change can cause organisms to experience conditions they are not adapted to. How do these organisms respond and keep up with a changing world? Our guest this week studies how a small, ubiquitous plant responds to both natural and experimental climate change to learn about the potential pathways to adaptation plants may follow. Dr. Johanna Schmitt introduces us to Arabadopsis thaliana, a tiny weed that can yield big insights into what the future holds for plants.

In many cells, RNA plays an essential role in regulation. Technological innovations are needed to further understand the role of RNA molecules in regulating basic biological function. Further, there is a need to expand the biochemistry toolkit to understand how large groups of RNAs are working in parallel inside living cells. The Spitale lab develops novel biochemical approaches toward understanding the role of RNA molecules in normal cell biology, as well as disease. Today we are going to...

What are coelacanths? Why would a marine fish contain chitin, a sugar that makes up the exoskeleton of insects? How do sharks sense fish? Why do we care about lamprey immune systems? Dr. Chris Amemiya from the Benaroya Research Institute studies these questions using comparative genomics. This research will improve our understanding of marine ecology as well as immunology, and holds implications for both the medical and biotechnical fields.
