Excuse me, why do you have teeth? How did they get in your mouth and where did they come from? Let’s ask researcher, tooth enthusiast, and Paleohistologist Dr. Yara Haridy.  She opened up the archives at Chicago’s Field Museum to chat about ancient skulls, drawers of bones, and the evidence that changed how we think about chompers. Drop your jaws as we discuss the origins of teeth, why yours hurt, the long-debated rumors of extinct species, how particle accelerators and paleontology worlds collide, what tools fossil pickers rely on, teeny tiny mysteries, why you should hug a tree before it kills you, and why a catfish might become your overlord.

Tongue twisters. Frosty holidays. Scandals. Big ol’ rodent butts. Let’s talk groundhogs with UCLA conservationist, field biologist, professor and Marmotologist, Dr. Daniel Blumstein. We cover what broadly is a marmot, the Buddhism and paganism of the midwinter slump, marmot parenthood, what they are singing into the wind, how to co-exist with one in your garden, why they don't get stressed about holiday bingeing, the real estate layout of a groundhog lair, how and why we celebrate Groundhog Day, romantic advice you should not take from a marmot, what to do if you want a marmot as a pet, why their blood boggled science, and the wandering etymology behind their aliases. It’s an episode you’ll want to hear over and over. And over. And over. And over.

Gassy veils! Orange sunlight! Alien life? It’s the sole goddess of our solar system: Venus. And to tour us through her beauty is the charming and enthusiastic planetary geologist and Venusian expert Dr. Vickie Hansen, a Senior Scientist at the Planetary Science Institute. In what is sure to become an instant classic, Vickie will delight you with tales of space probes past and future, dazzling terrain, myths, melting machinery, “noodle data,” analogues to Earth, tectonic misconceptions, and reactions to self-help books that capitalize on our solar geography. Also: what does Venus smell like?

Get ready for an absolute banger of an encore episode with 5 experts: René Brooks of BlackGirlLostKeys.com, TEDTalk speaker and How to ADHD YouTuber Jessica McCabe and neuroscientist Dr. Jahla Osborne of University of Michigan. What is it like to get diagnosed? How do you know which medication – if any – is right for you? Why is there such a spike in ADHD diagnoses during the pandemic? Autism and ADHD: what’s the deal? What accommodations should a person ask for? How can you have a strong relationship with one (or more) ADHD brains? What if your boyfriend juggles flaming swords for fun? Sure there are tips and tricks, but get ready for the pep talk and self-acceptance honestly everyone needs to hear. Plus: two cameos from past Ologists: Dr. Tiara Moore (Forensic Ecology) and Dr. Adam Becker (Quantum Ontology). Oh, and how this relates to Alie’s own Dadbrain. HERE WE GO.

Focus. Productivity. Relationships. Distraction. Neurodiversity. How do you know if you have ADHD? How can you get others to understand your ADHD brain? What are your treatment options and how can they help? In this encore of our wildly popular Part 1 episode, we talk racing thoughts, brilliant brains and the causes and effects of Attention-Deficit Hyperactivity Disorder with the world’s leading expert, Dr. Russell Barkley who is A BIG DEAL. Psychologist, retired professor of clinical psychiatry, author and speaker, Dr. Barkley has a personal connection to ADHD and has studied it for nearly 40 years. Is it all cute quirks? Nope.

The microbiome is back! In 2018, we chatted with Dr. Elaine Hsiao - a UCLA microbiome researcher– and learned all about the hot cauldron of your guts. In this 2025 update bonus, we chat again with Dr. Hsiao to get updates on the last 7 years of her research. We also stop by White Plains, New York to hang out with Dr. Miguel Freitas, lead nutritional microbiologist and director of the non-profit Danone Institute North America, and ask a million questions about good vs bad microbiota, how they simulate a human gut in a lab, what exactly is a pre-biotic vs. probiotic, why are they such good friends, how diet can impact not only your gut health but also your heart and your brain — and if friendly yogurt critters are robust enough to make the journey from your mouth to your toilet.

Dehydrated eggs. Airborne tortillas. Pouches of chicken. Tang. Work up an appetite for space food with artist, designer and Astrobromatologist, Maggie Coblentz. She shares how the intersection of design and science led her skyward, doing experiments on zero G flights, and shipping miso into space. We also talk Martian gardening, stinky roommates, booze bans, contraband corned beef, velcro fatigue, the ethics of space tourism, how to make barbecued wings in orbit, and addressing the conspiracy of astronaut ice cream.

Fronds. Forest dwellers. Spores. Houseplants. Queer icons. We’ve got ferns. The charming and hilarious professor and author of “Ferns: Lessons in Survival from Earth’s Most Adaptable Plants,” Dr. Fay-Wei Li, tells me all about fern evolution, what ferns not to have in your house, the most expensive ferns, the tastiest ferns, mathematical mysteries, and a genome that makes no sense, to me or a lot of Pteridologists. Also, can Between Two Ferns save science? This episode is, in Fay-Wei’s words, “ferntastic.”

Note: if you haven’t already heard it, please start with our original, May 2024 episode with Dr. Moses: 

Genocidology (CRIMES OF ATROCITY) Part 1

A lot has happened since then, and author, scholar and genocide expert Dr. Dirk Moses was kind enough to return for a 2025 episode. We cover how public and legal sentiment has changed since our first episode, and discuss his recent paper, “Introduction: Gaza and the Problems of Genocide Studies,” which includes a roundtable discussion with dozens of experts. Also: some behind-the-scenes influences regarding Gaza in the media, humanitarian law precedents, munitions and the Geneva Conventions, myths, the problems surrounding the language of transgression, new research, up-to-date statistics, and how protests have been criminalized. 

Like that first Genocide episode, this one would not be possible without the input, research, producing, and additional writing of Mercedes Maitland, who joined me on this interview once again with her questions for our expert. So, huge thanks to her for that passion, hard work, and tireless advocacy for human rights. 

Donations went to Gaza Hand of Salvation Initiative and the City College of New York Colin Powell School – Student Emergency Fund

Bison bison! Not just something to holler into the sky, but also the scientific name for North America's majestic wild bovines. In this encore, we explore a beast that once roamed the plains in the tens of millions. What's up with their humps? On what occasion do they wear capes? What noises do they make? How many are out there? What are the best ways to help them? In this special episode, you get 4x the usual number of ologists as we talk to archeologist Dr. Ken Cannon, wildlife biologist Dr. Dan McNulty, Alie's cousin Boyd and his wife Lila Evans, of the Blackfeet Tribe, who are bison ranchers based in Northern Montana. Also, once and for all: is it buffalo or bison? And can Alie hug one?
