Dr. Danielle Grotjahn
We often imagine a cell as a large balloon filled with jelly, but really it is more like a large city. Packages need to go from one place to the other in an organized fashion as to not disrupt other processes. For example, when we need an item, we go to the store or click away on retail websites, but how do these items find their way to the retail place or our house? There are vehicles on roads and highways that are utilized for distribution. Much like the infrastructure that we use everyday to move cargo around our cities, the cell has its own system to deliver goods from one place to another. What are the 18 wheelers of the cell, how do they move such important packages, and how do they know where to go? Cytoplasmic dynein is a protein complex that transports molecular cargo along and plays a key role in the intracellular trafficking network. Dr. Danielle Grotjahn utilizes specialized imaging techniques to study these structures and the function of motor proteins.

What if you could prevent something bad from happening? When it comes to epilepsy, you never know when a seizure could happen next. The ability to predict an incoming seizure can be a game changer. Today we have the pleasure of chatting with Dr. Jeanne Paz about her incredible work aimed at seizure prediction and prevention.
Dr. Tricia Van Laar
We are all probably familiar with antibiotics, we have probably even taken them.
Resistance to antibiotics have been in the news recently. But what is it? How does antibiotics resistance develop and are there ways to combat it? Dr. Tricia Van Laar chats with us and shares insights on antibiotic resistance.
Dr. Alsion Davis Rabosky
Red on yellow, kill a fellow. Red on black, friend of Jack. Some species use bright colors in different combinations to tell potential predators to back off, bub. Eat me and you'll be sorry. But not always.... Throughout the animal kingdom, species have evolved ways of faking out their enemies. Dr. Alison Davis Rabosky tells us about natures con artists, the mimics, and how these crafty creatures can actually drive evolution in their poisonous counterparts.
Dr. Whendee Silver
When you think of ways to slow down climate change, what pops into your mind? Reduce, reuse, recycle!! Perhaps to never use fossil fuels again? These are things that we, as humans, can actively do to decrease our impact on earth's climate. We're not alone in the fight against climate change tho-- plants play an important role just by being, well, plants. This week on RadioBio, Dr. Silver from UC Berkeley tells us about how plants, together with soil microorganisms, help capture carbon from the atmosphere and store it in the ground; and what we can do to help.
Dr. Sharon Strauss
Do you ever stop and smell the flowers? Do you feel like you only like certain kinds? Well, a bee would agree. Did you know scents are different because of species interactions? In a field of flowers, there are a lot of complex interactions at play that allow those flowers to coexist. But how does it all work? Today on RadioBio we talk with Dr. Sharon Strauss about the complexity behind species coexistence.
Dr. Jarmila Pittermann
Extreme drought is one of many impacts of climate change. Globally, we have seen droughts increase in duration and intensity, with many negative impacts on natural ecosystems, crops, and our economy.
This begs the question - how do plants deal with drought?
Our guest today, Dr. Jarmila Pittermann, studies plant ecophysiology — how plants are structured and what that structure means for how plants respond to their environment. She seeks to understand how different plants use different strategies for surviving drought by zooming in to look at their internal workings, their plumbing. Her exploration of the various systems plants have developed for moving and using water is showing us that some plants use some pretty unique methods for dealing with drought.
Dr. Anita Sil
Infections occur when foreign invaders take root in the human body. When most people think of infections, they think of bacteria and viruses. These however, are not the only invaders our body has to watch out for - fungi are also able to cause disease in humans. You all may be familiar with mild fungal infections, such as athletes foot and yeast infections. Some fungi however can cause life threatening illnesses. One fungus, Histoplasma capsulatum, is capable of causing severe respiratory infections. Dr. Anita Sil from UCSF chat about how this fungus gets into our body and how we clear it.

Vernal Pools Dispatch
Coming to you from the backyard of UC Merced - The Vernal Pools Dispatch!
Rolling grasslands at the edge of the UC Merced campus and the foothills of the Sierra are bright green with temporary pools in the spring and a dry golden yellow in the fall. Believe it or not, this dynamic ecosystem is home to a diversity of unique flora and fauna. RadioBio interviews four scientists who each study a different part of one of California’s most surprising ecosystems: vernal pools!
