Petri Dish

Petri Dish

Profane, insane, and 100% primo science, Petri Dish is a no-BS podcast that explores the wildest subjects in modern science with clarity and evil joy. Hosted by Sean Allen, a Nanoparticle/Immunology Researcher, and Nathan Allen, his "screenwriter" brother, Petri Dish fuses hard science with a freewheeling and madcap conversational style. Cannabinoids, Plague, Cats, the dreaded Candiru, and the even more dreaded Covid-19: all these and more are dissected with intellect and irreverence, dropping every week. So reject ignorance. Join the Scientific Revolution. Join Petri Dish.

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.

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!

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?

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.

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 ...

Hi everyone! This week's episode is about recent work trying to figure out a way to make a baby mouse that has two genetic dads. We also dive into why mammals don't seem to have virgin births!References:

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!

Here in our first episode on our 2-parter on Black Holes, we explain what a black hole is in theory and what it probably actually is in practice. 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:

In February, a train was partially derailed while carrying a number of chemicals. The subsequent attempt at containment resulted in the release of many thousands of gallons of these chemicals. What were those chemicals? What are the risks involved in their release?

On this week's episode, we complete our series on desalination by discussing the near future technologies that are coming to either improve or attempt to supplant the current front runners that we discussed last week. We will also discuss the downsides of desalination and work that is being done to try to minimize or circumvent them!

Hi Everyone!

We're interrupting our series on desalination to put out a quick rerelease of one of our episodes on Fungi! We're doing this in honor of the season 1 finale of The Last of Us, which heavily features a fungus called Cordyceps, which we covered in this episode. Check it out and learn more about cordyceps, similar fungi, and much nicer fungi that improve human life rather than turning us into freaky zombies.

Climate change is happening, two billion people don't have a reliable and safe supply of fresh water, and the problem isn't likely to get a whole lot better on its own!

Desalination is the process of making fresh water from salt water, but what is the current state of the technology? Find out on this episode of Petri Dish! Next time, we will discuss the near-future iterations on desalination!

While science and medicine have come a long way over the centuries, there are still illnesses that cannot be explained -- and many of them are autoinflammatory disorders. Many people all over the world have been inflicted with these disorders with no clear cause.

But recently, scientists were able to find a mutation that can help explain what some of these people are going through, a mutation that led to the identification of an au...

Occasionally we do episodes where we speak about a couple different topics that don't have a specific underlying theme -- they're just fun science papers that have cropped up recently! This time we discuss the confluence of two different hot technologies, CRISPR base editing and CAR T cells. We also do a little dive into Roman Concrete!

We return with our second episode on Death, the final frontier! What is it? Actually though, like what determines the moment when someone dies? This question has actually had a different answer through the years, and we dive into the definition and how it has changed as technology has advanced. We finish with an example of cutting-edge technology that may further muddy the line between alive and dead!

Hi Folks! Part 2 of our series on coffee focuses on how coffee beans can be imparted with different flavors through their picking and processing!

We mentioned this in the show notes for the last episode, but we will be going on a couple month hiatus while Nathan and Stacey take a vacation in Korea! We will be re-releasing some of our older episodes in the meantime, in case people are really itching to listen to our dulcet tones.
