Petri Dish

By 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.

Ep. 132 Crustaceans Pt 2: Everybody Wants to Be a Crab
Hi everyone! In part 1 of crustaceans we laid down a lot of groundwork on what crustaceans even *are*. But here in part 2 we wanted to spend some time talking about a hot topic in crustacean-world: "carcinization" aka "stuff keeps evolving into crabs"! But not *all* crustaceans are yearning for crabdom -- there is a specific group called anomurans that really dig that crab vibe. Learn about them and what it takes to be a crab on this episode of Petri Dish!

Ep. 131 Crustaceans Pt 1: What the F*** is a Shrimp?
Hey everyone! On this episode of Petri Dish we ask the question everyone has been asking since time immemorial -- what the fuck is a shrimp? Like seriously, what is that shit? No, I mean, I ask because there are so many things called shrimp -- fairy shrimp, mantis shrimp, seed shrimp, and so on... And while they look kind of similar to one another, they really aren't all that related, separated by hundreds of millions of years of evolution. But they all belong in the big group of animals called 'Crustaceans', along with crabs and lobsters! And insects. Wait, what? Yeah, this group of animals is a total mess, so let's talk about it!

Ep. 130 Kelp Pt 3: Chew on That
Our final episode on kelp! We've spent the last two episodes discussing natural kelp forests and some of the fun things we can use kelp to do like bioremediation. This episode, we talk about the nutritional value of kelp and some food uses, including in food for cows!

Ep. 129 Kelp Pt 2: Fixing, Farming, and Filtering
Part 2 of 3 of our series on Kelp! Part 1 was all about natural kelp forests and how cool they are, but part 2 is focused on how humans can EXPLOIT kelp for our own purposes, muahahaha! Can we use kelp to fix all that carbon we've been releasing into the atmosphere to help us reverse climate change? What about farming kelp for food and products? What about using kelp as a fancy filtration system to clean up water supplies? Find out about all that this week!

Ep. 128 Kelp Pt 1: Forests Au Naturale
Hey everyone! This next series of Petri Dish is about Kelp, due to strong demand from Nathan. Kelp are those big floaty plant-looking things (but they aren't plants, technically)! This episode, we dive into natural kelp forests and how they're both environmentally great and also at risk of shrinkage. In future episodes we'll cover kelp farming and the fun uses of kelp!

Ep. 127 Koji: A Fancy Fermenty Thing
This week we have a one-off episode for you on koji! Koji is a Japanese fermented ingredient with analogues in other East Asian cuisines -- basically it is a grain that has some mold growing on it. But oh, the fancy foods you can make with it! Soy sauce, miso, sake, and so many other delicious things! But how does koji get made? What is the deal with the mold? And what sorts of fun things could you make at home with this fuzzy stuff?

Ep. 126 Afforestation Pt 2: The Great Green Wall
Hi folks! Welcome to part 2 on Afforestation/Reforestation! Last time, we discussed the Chinese effort to plant a ton of trees, both to combat desertification and to capture carbon, with complex results in terms of water availability and climate across the whole of China. This time, we discuss the Great Green Wall of Africa, an effort to stem the growth of the Sahara (whether it is growing or not is actually a matter of some debate...). We'll also talk some about Sargassum! Hop on in! Use the code POD at stamps.com to get big discounts this holiday season!

Ep. 112 Multiple Sclerosis Pt 3: Current and Future Treatments
In this final episode of our series on Multiple Sclerosis, we discuss the current treatments available for the disease, mainly for the relapsing/remitting form. We then discuss what some of the future treatments look like, including those currently in clinical trials, that may be able to help treat the progressive form of MS!

Ep. 111 Multiple Sclerosis Pt 2: Missing Myelin
Last week we started our series on multiple sclerosis by discussing the history of the disease, the symptoms, and the various forms of the disease. This week we dive into the biological cause of the disease. What makes multiple sclerosis pop up? What sorts of genetic or environmental factors seem to play a role? We also recommend you check out Eps 63/64 on the blood brain barrier, Eps 56/57 on autoimmune disorders, and Ep 38 on the adaptive immune system for more background information!

Ep. 108 Artificial Sweeteners Pt 2: 'Natural'
Hey everyone! This week's episode continues our discussion on non-nutritive sweeteners! Last week we discussed synthetic sweeteners, the ones made in labs like Sweet N Low or Splenda. But there are sweeteners on the market that are 'natural', like stevia or monkfruit. What is up with those sweeteners? Are they just different kinds of sugars, or are they something else entirely?

Ep. 105 Alzheimer's Disease Pt 2: FDA Approval
I don't know if y'all have heard or not, but a month ago the FDA approved a drug for the treatment of Alzheimer's Disease, the first one in a couple of decades. This approval was met with the resignation of some members of the FDA's own scientific advisory group, which had recommended that the drug not be approved. What is going on here? Let's get into the science behind this drug, how the approval process works, and what this whole situation means! Featuring a promo for Just the Zoo of Us, a great podcast about animal facts!

Ep. 93 One in a Million: Adenovirus COVID Vaccines and Blood Clots
https://baxterblueglasses.pxf.io/c/2544961/1031264/11471  The AstraZeneca and Johnson & Johnson COVID vaccines have been in the news recently, suspected of causing a rare blood clotting issue in a small number of people who receive them. What is going on with these two vaccines, while the Moderna and Pfizer/BioNTech vaccines don't seem to have this problem? What are blot clots anyway and are the one in a million and on in one hundred thousand blood clots seen here just your average clot, or something more unusual? There is plenty that scientists don't know yet, but whatever we know, we want to share with you! Feat. a promo for Snark Tank, a pop culture podcast!

Ep. 92 Regeneration Part 3: Newt Eyes and Lizard Tails
Why can newts grow back part of their spine and brain while we're walking around unable to even heal a broken heart!? Even amongst us tetrapods, the ability to regenerate varies wildly! Learn how amphibians regenerate their body parts, how lizards regrow their tails, and how little human kids can regrow the tips of their fingers, apparently!

Ep. 91 Regeneration Part 2: Decapitating Sea Slugs
Last week we talked about hydra and planarians, which you can slice and dice into little bits and all the bits will regrow into new little jabronis! But they're pretty distant from us on the evolutionary tree, so how about we get a little closer! This week, we talk about sea slugs and zebrafish, two aquatic critters with pretty impressive regenerative abilities! Feat. a promo for I Said God Damn! A True Crime Podcast!
