PODCAST

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

Hello and happy almost Thanksgiving to folks in the USA! In honor of a holiday that features stuffing yourself, we're covering the muchies-inducing plant, Cannabis, and the chemicals it produces. With more and more locations around the world decriminalizing and legalizing marijuana, this is a great time to ask yourself "what the fuck does this shit actually do, like real science-wise"? This episode, the first half of a two-parter on cannabinoids, covers info about the plant itself, the chemical

Hi Everyone! This week Sean and Nathan are joined by certified young person Griffin Allen, who has street-level knowledge about VAPING -- the recently-in-the-news drug delivery phenomenon that has seen an unexpected uptick in sending people to the hospital over the past year. How does vaping work, and how does it compare to traditional smoking? What can you vape? When people are sucking on USB drives, was that actually them vaping or are they just dumb? We'll get into it! Remember though! We're not

This weeks episode is a spooky sci-fi romp about how we're hooking up brains to computers and minds to machines back to minds again! Except it is all real science! Tune in to hear Nathan and Andrei tell Sean he's crazy, learn what Elon Musk is doing with his latest company, and whether this technology is going to destroy humanity before CRISPR does.

2019/10/21

Part two of CRISPR and genetic editing! This time, we talk about what plants and animals we have already CRISPR'd! Also, we discuss CRISPRs in the context of human health. Then, at the insistence of Nathan and Andrei, Sean is forced to discuss the ethical conundrums that come up surrounding the democratization of genetic modification. Nathan starts this episode out with a trigger warning about GMOs, but a less facetious trigger warning for this episode is that we discuss CRISPR and genetic

Tenth episode of Petri Dish! Going to be honest, didn't think we'd make it this long. Sean and Nathan have a special guest for this episode, Andrei Daye.

In case you hadn't heard, CRISPR-Cas9 is the hot new way to genetically modify DNA, and has been used in labs for all sorts of research including the controversial CRISPR-ing of those twins in China!But this

Our animal episodes seem popular, so episode 9 is a return to silly beasties -- in this case Sean and Nathan are talking about organisms that like to live in EXTREME environments, organisms called extremophiles.Sean and Nathan discuss the plural of octopus, with Sean starting out wrong with octopi (wrong!), Nathan offering octopussies (hmm) then switching to octopuses (best accepted answer). Sean tosses in octopodes, which is the correct plural form based on the etymology, but pretty much no one

The Origin of Life

This week Nathan and Sean discuss the origin of life on Earth! Every cell in your body came, ultimately, from the zygote that was made when your dad’s sperm wiggled its way into your mom’s egg. And those little dudes came from another cell, and another, leading all the way back in time - a physical chain of cell divisions leading back to that very first cell. But what existed in the moments before that? Where did that cell come from?Error Thingy: Nathan asked Sean for a timeline on the origin of

Episode 5 of PETRI DISH! This episode is a prequel of sorts to our upcoming 2 part series on CLIMATE CHANGE (oh no!). In this episode, Sean tries to discuss ECOSYSTEM ENGINEERS with Nathan, who keeps calling these critters Environmental Engineers, which is 50% right. He seriously did it multiple times, just couldn't say ecological.Anyway, what's up with these engineer guys?
