Ologies with Alie Ward

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.

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?

We’re back with Dr. R.J. “Rocky” Gutiérrez to answer listeners’ questions on owls. How much wisdom lies behind those big, immovable eyes? Are owls good or bad omens? What’s their proclivity for snatching hats? Is The Staircase owl theory plausible? Is it ok to hoot back at them? What do you mean one of their toes is reversible? This episode’s got the answers, plus info on owl migration, conservation, burrowing, disco dancing, and more.

OWLS. FINALLY. In no particular order: what’s up with their eyes, legs, hoots, feathers, silent flight, nests, folklore, necks, barfs, conservation status, and omens? Go take a walk or sit on a porch in the dusk and make friends with Rocky. Dr. R.J. “Rocky” Gutiérrez is a celebrated researcher, Professor Emeritus at the University of Minnesota, a legend in the owl world, and simply one of the loveliest ologists. He’ll take us on a trip next to a river, scrambling up some trees, over rocky terrain and through the forest to learn why owls are so magnetic. Yeah, I called owls the best bird. Not backing down.

Metal poisons. Odorless ones. Toxic plants. Iocane powder, arsenic, old lace, poisons as self-defense, black mirrors, Aqua Tofanas, movie myths, and the start of testing for that which ails or kills you: we’ve got Historical Toxicology with Pulitzer Prize-winning science author & chemistry connoisseur Deborah Blum. She wrote the beloved “Poisoner's Handbook: Murder and the Birth of Forensic Medicine in Jazz Age New York” and takes us through a spooky walk in time, when chemistry was magic and homicide was an easier feat.

What is evil? Who is evil? Does evil exist? Who decides? Can we scream over turkey at grandma’s house? Let’s chat Critical Ponerology with scholar, professor, author of Evil: A Critical Primer, and a gem of a person, Dr. Kenneth MacKendrick of the University of Manitoba. He’s been teaching courses on the notion of evil for 25 years and it’s a much deeper rabbit hole than you’d ever expect. So rub your fingers together and enjoy a discussion about different cultural approaches to evil, if your toddler is evil, vampires, angry mobs seeking vigilante justice, news personalities saying unhinged things, and subjects vs. objects. Also: why you should be nicer to your coffee table.

Cockroach milk for Spooktober. STAY HERE. Don’t tell me you like haunted houses and slasher films but can’t listen to a lovely conversation about how cockroaches make milk to feed their young. It’s one of the most nutritious substances on Earth, and I own some. Sort of. Coem along for a brief and enthralling discussion from two researchers, Dr. Joshua Benoit and Dr. Sinead English, all about why and how some insects give live birth and nurse their young. What does it taste like? Will we replicate it for barista use? And why didn’t I get to eat any on TV?
