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 w…

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 adapt…

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.…

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 env…

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 pr…

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 …

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.

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. Wh…

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? T…
