概要

 #Diatoms #DONA #Ludoliminal #Microbiology #BoardGames #Science In this episode we're going microscopic to talk about everything Diatoms! Starting from the game by Ludoliminal and going through the classic (and obscure) Victorian art form of arranging these beautiful glass-shelled organisms on microscope slides, our special guest Laura Aycock--collections manager at the world's *largest* diatom herbarium--helps us understand all the beauty and wonder of these tiny, shimmingering marvels. From tepid ponds to hot springs to arctic ice, diatoms are everywhere, and they do a lot for us while looking absolutely fabulous. So grab a microscope and prepare to never look at pond scum the same way again!

Jason Wallace 0:10 Today, we will be talking about diatoms by ludoliminal Games. All right, everyone, welcome back to gaming with science. This is Jason. This is Brian, and today, for our special guest, we have Laura Aycock. Laura, can you please introduce yourself? Laura 0:25 Sure. I'm Laura Aycock. I am the Collection Manager of the diatom herbarium at the Academy natural sciences in Philadelphia that's affiliated with Drexel University. And I've been working with diatoms for about 15 years, and I find them fun and enjoyable. Brian 0:38 That's really cool. Thank you for coming on, Jason. How did you manage to get the exact right person to come talk to us? Good job Jason Wallace 0:44 being very persistent with emails. Laura 0:46 Theres also not very many of us Jason Wallace 0:49 there is that when there's actually a website called diatoms.org, that has all the nation's top diatoms scientists linked to it, somehow, it's not that hard to find someone. So before we get into this lovely game about absolutely beautiful, microscopic creatures. Let's start with our fun science facts. So Laura, as our guest, we usually pass the privilege to you to start. Do you have something you'd like to share with our audience? Laura 1:09 Sure. My favorite fact about diatoms is they produce about a fourth of the oxygen we breathe. So they're very important to life on Earth, and we wouldn't survive without them. Brian 1:16 So trees get all the credit, but they're stealing that Jason Wallace 1:19 we talkabout plant blindness, where people just don't look at plants. There's definitely what macroscopic bias, where we just don't think about all the things that aren't within, you know, human size scale. So yeah, trees get all the credit, but all these little microbes are actually doing a whole bunch of the work there. Laura 1:33 Yeah, diatoms, along with other groups of algae, actually produce about half of the oxygen we breathe, so they are as important, if not more important, than land plant, but no one thinks about them, sees them, or really acknowledges them. Brian 1:44 So let me think. Then I'm thinking about this track of carbon dioxide that we've been seeing sort of dip and rise and dip and rise and dip and rise. Now that dip and rise that's from the like Alpine forests in the northern continents, right? But the stable activity that's presumably all the algae in the ocean, right? Or do they also fluctuate on an annual cycle? Jason Wallace 2:04 I'd assume they'd also fluctuate annually, just because of temperature, if nothing else. Laura 2:07 It depends on the environment. ...
