Pour yourself something warm. Let it drizzle outside. This one's for the curious.
The Mark & Toddcast is your weekly escape from the algorithm, the outrage cycle, and whatever fresh hell is trending. Broadcasting from the rainy heart of Portland, Oregon, two friends have spent 11 years and over 300 episodes doing exactly what you wish you could do at your favorite dimly lit neighborhood pub: sitting down with a pint and wandering through whatever's genuinely interesting.
Consider us comfort food for your brain.
Instead, expect pure Pacific Northwest chill and unfiltered curiosity about topics like:
-
Why we absolutely hate the sound of our own voices
-
The secret origin of the biohazard symbol
-
America’s classified, Cold War plan to nuke the moon
-
The Stanford Prison Experiment (and why it was actually kind of BS)
-
Portland’s very own infamous Barbie-hacking culture jammers
-
The unsolved mystery of the Toynbee Tiles
-
And yes... the actual science of farts
What’s in an Episode?
-
The Catch-Up: A little life banter between two longtime friends navigating the Rose City.
-
Just the Headlines: A quick spin through the weirdest, wildest science and culture news of the week.
-
The Deep Dive: A 20-minute, high-level plunge into whatever strange subject one of us couldn't stop reading about.
Meet Your Hosts:
-
Mark spent his twenties operating nuclear reactors for the Navy before coming home to Portland's Silicon Forest to keep the machines that build microchips running. Now, he’s a technical director helping companies get found online.
-
Todd has lived several lives—ad copywriter, artist, Newsweek-published writer, and an unrepentant Madonna superfan. Today, he’s a local therapist helping people untangle their stories and reconnect with the humans around them.
Pull up a chair. Grab a local beverage.
Science is funny.

Thursday Sep 07, 2023
The human body is 2.5% metal, which we need in order to produce electricity, heal our skin, and make us move and think, among other things. We're not saying we're robots, but we're sort of robots. This week we dive into the weird world of metals, and how exactly our bodies need and use them to pilot the other 97.5% of us that's an organic, goopy pile of flesh and guts.

Many of us have heard of the Biosphere 2 project - it was one of the main news stories of 1991, which Todd just visited in Arizona. But many don't know the full history, controversy, and eventual take-over of the project from the genius hippy theater freaks who built it to.....yes, Steve Bannon, and then eventually the University of Arizona.

This week we take a short look into an indigenous South American warrior named Galvarino, who, despite having his hands cut off by Spanish Conquistadors, strapped knives to his stumps to rally his fellow Mapuche community into fighting back. In the news: the Portland Wolverine is sighted again, a promising anti-Alzheimer enzyme, remembering Darcelle, the USS Robert Smalls, a Sriracha shortage (or is there?), REI closes its Portland location, and more.
