  • Ep. 184 How to Make a Drug Pt 1: A Target

    Hey everyone! Today's episode is about getting into the nitty gritty of drug discovery. We often benefit from the research and development that goes into the creation of drugs we use to treat illnesses without really understanding what goes into that process. In this first part, we will discuss how you conceptually begin the process.

  • Ep. 183 Influenza Pt 4: Vaccines and Pandemics

    Sorry for the COVID-related break in episodes everyone! In our return, we complete our series on influenza by discussing past epidemics and pandemics to understand how influenza has repeatedly led to large scale medical events. Then we will finish by discussing the current and future state of influenza vaccines!

    • Ep. 182 Influenza Pt 3: Whaddya Gonna Do About It?

      You've had the flu. You've had a cold. Maybe you've even had allergies! But how can you tell them apart? And if you even figure out that you do have influenza, are there any treatments you can take that can help?

    • Ep. 181 Influenza Pt 2: The Piggies

      Last episode we discussed the current H5N1 flu that is hitting birds pretty hard. But is bird flu different from swine flu? Is there just a 'human flu', or do we only catch influenza from other animals? Let's get into the evolutionary history of the flu and primary hosts!

      Today's episode is the first in a four-part series on influenza! This time we are covering just enough background information to discuss the recent H5N1 pandemic in birds, which was responsible for the egg shortage and has been killing a lot of wild birds.

    • Ep. 179 The Silence of the Plants

      Sure, plants can sometimes smell good and they do cool stuff like make carbs for us to eat and oxygen for us to breathe. But they sort of look like they're just passively sitting there, right? Just chilling. If only we could hear just a slightly broader range of frequencies, we would hear a whole new world of plants -- one where they are complaining about being thirsty! Find out about the screaming clicks of dying plants, this week on Petri Dish!

          Today's episode is our second and final episode on Black Holes! We cover some exotic black hole concepts, like whether they are a source of dark energy, what a white hole is, and whether black holes are fuzzy or not!

We dive into why it is still hard for us to really know what the true nature of black holes are and we discuss the different kinds of black holes.References:
