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.

This week we take a look into space by discussing the weird interstellar object known as 3i/Atlas, conspiracy theories about what the object may be, and how the original Apollo astronauts figured out their exact location on the moon without the aid of any GPS.

We're finally back after a two month hiatus, and we threw out the format of the show to see where the conversation took us. The discussion veers from drying off after a shower to AI cats to what g-force actually is, to our final hero of the week: the teacher fired for using fart spray. Enjoy!

It's been a minute, but Mark and Todd are back for an end-of-summer news wrap-up, including great news for promiscuous koalas! (And for those looking for a break from last week's big news story, we don't discuss that here at all, so we're a nice escape from that particular news cycle.) Come hear about Texas's new maggot factory, DOGE's lack of efficiency, Oregon's fallout from Medicare cuts, the Denmark zoo wants your pets, bugs that cause "Kissing Disease", the West Coast's new health alliance, and magic dust that prevent the Amish from getting allergies. Enjoy!

The Unipiper noted that this movie begins like "Stand by Me," but ends up like "Reservoir Dogs." While not exactly right, he's not far off describing this 2000 movie with some legitimately shocking twists and compelling turns. But because this is a movie made around Portland (Vernonia, to be exact), it falls short of being an actual good movie. Find out why on this month's episode.

Our Portland at the Movies server is having issues, so in the meantime, here's the latest episode of PatM, which looks at the 2006 Alan Arkin film "Raising Flagg."
"This month we head out to the Oregon countryside (and St. Helens!) for this family comedy (?) drama (?) about a cantankerous old man (Alan Arkin) healing the relationships (?) between him and his many, many children. Also, there's a lawsuit about sheep piss. Can Glenne Headly or Lauren Holly save this? Cook yourself some organic, fertilized eggs and pull out that rocking chair to find out."

So what is a neutrino, and how do you find and measure something practically invisible? Find out on this week's episode.

Our planned interview fell through for this week, but that gives us an opportunity to catch up on all the news we've been putting off. Come with us as we meander through 250 million bees on the loose, acid leaks and new venues in N. Portland, no more thicc plastic bags, what happens in your brain during an 'a-ha!' moment, RFK Jr.'s "MAHA" report based on non-existent studies, night owls and dementia, a Utah study on trans people finds conservative sponsors of that study wrong, AI resorts to blackmail, and bear cubs raised by people in bear costumes.

With so many so-called "alien encounters" throughout history, has there been any consistency in people's descriptions? This week we dive into the top 5 most recounted alien types who may be living among us right now. Yes, there are lizard people (two kinds!). In the news, Oklahoma forces schools to teach conspiracy theories, Utah bans fluoride, U.S. cities are sinking, life expectancy in the south is now on par with the year 1900, RFK Jr. implores people to not listen to him about medicine and science, who falls for pseudo-intellectual bullshit, and monkeys using leaves as...um..."tools." I want to believe.
