Vox reporters trace how Botox, brain-speech implants, and scientific disputes actually happened.

The gist

Unexplainable follows scientific questions until they become stories about people, institutions, and the limits of certainty. Recent episodes move from male birth control and brain-to-text AI to Botox, alchemy, snow, neuroscience, and family memory.

About Unexplainable

Unexplainable is produced by Vox and built primarily around one-on-one interviews between a host and an outside expert, researcher, or journalist. A given episode might follow a science journalist through an investigative story, such as the collapse of trust in NOAA's cod survey data, or bring on a historian of chemistry to recreate a centuries-old alchemical recipe in a lab. Recurring themes include the history of medicine and science, moments where discoveries happened by accident rather than design, and stories where scientific data collides with public trust or lived experience. The show also periodically runs personal essay episodes, such as a departing host's story about her Cuban grandmother's use of Vicks Vaporub, that connect a family or immigrant history to a broader scientific or medical thread. Several hosts appear across the sample, including Sally Helm, Bird Pinkerton, Amy Padula, Noam Hassenfeld, and Julia Longoria, with episodes crediting a rotating team of producers and editors rather than a single fixed host. Guests are typically subject-matter experts, academic researchers, or fellow journalists rather than celebrities, and are chosen for direct involvement in the story being told. Tone throughout is educational and narrative, favoring close reporting and scene-setting over debate or opinion. The show suits listeners interested in the history and process of science and medicine, health and biotech developments, and narrative science journalism rather than quick news updates. Episodes run in the roughly 20-to-40-minute range and are structured as single-topic deep dives rather than roundups. Production includes on-location reporting (a New York snowstorm, a fisheries community) alongside studio interviews.

Made for: Listeners who enjoy narrative science and medical journalism that digs into how a discovery, treatment, or scientific dispute actually unfolded.

What sets it apart: Combines expert-interview science journalism with occasional personal essay episodes tying family and immigrant history to scientific topics, hosted by a rotating team rather than one fixed presenter.

Unexplainable takes listeners right up to the edge of what we know…and then keeps on going. The Unexplainable team — Noam Hassenfeld, Julia Longoria, Byrd Pinkerton, and Meradith Hoddinott — tackles scientific mysteries, unanswered questions, and everything we learn diving into the unknown. New episodes Mondays and Wednesdays. From Vox and the Vox Media Podcast Network.

As heard by us

Based on 6 episodes we listened to · September 2026

Reported narratives make scientific uncertainty concrete, tracing how evidence, technology, and trust behave outside tidy explanations.

Unexplainable turns scientific uncertainty into reported stories with people and consequences in view. Noam Hassenfeld and Julia Longoria ask plain, persistent questions, moving between contested cod surveys, a brain-to-text interface, and the disputed factual status of Oliver…

Best episodes of Unexplainable

Short reviews from the PlayNext desk, based on the episodes we processed.

Is male birth control finally here?Apr 1, 2026

A clear look at male birth control, with real trial signal but no false finish line.

The piece treats male birth control as a real question, not a punch line, and that keeps the focus where it belongs. It spells out the main approaches in plain language: NLS-133, an on-demand pill taken 90 minutes to three hours before intercourse, and ADAM, an injected…

Mi VickicitoMar 30, 2026

Vic's vapor rub opens a restrained family story about memory, Cuba, and a conversation still waiting to happen.

Vic's vapor rub becomes a way into family memory, and the piece works best when it stays with that pressure: the speaker wants to ask about a grandmother and Cuba, but does not yet know how. That uncertainty gives the story its shape.

Casey gets his voice backMar 25, 2026

A patient, clear-eyed look at brain-to-text AI and the effort behind Casey Harrell being heard.

Casey Harrell's halting conversation with Julia Longoria turns a brain-to-text AI interface into something more complicated than a breakthrough demo.

Oliver Sacks's not quite nonfictionMar 23, 2026

A measured look at Oliver Sacks, medical storytelling, and the trouble that follows when case studies become part fable.

Unexplainable uses Oliver Sacks to ask how far medical storytelling can bend before it stops being evidence. Rachel Aviv, a New Yorker staff writer, describes admiring Sacks's gift for entering a patient's inner life, while also tracking his own unease about stories he knew were…

The accidental rise of BotoxMar 18, 2026

A sharp, odd history of how a feared toxin became Botox, moving from eye care to wrinkles to throat medicine.

Unexplainable treats Botox as a medical oddity with a surprisingly crooked path: a poison once tied to spoiled sausage becomes botulinum toxin, then a branded drug famous enough to be shorthand for wrinkle treatment, and finally the thing Sally receives in her throat for a…

Who are we to fight the alchemy?Mar 16, 2026

A patient look at alchemy that finds real experiments inside centuries of strange claims.

Unexplainable treats alchemy as more than a punchline. Lawrence Principe starts with a high school library encounter and works toward a simple but useful question: what if old alchemical books deserve a closer reading?

Snow day!Mar 11, 2026

A snowy Brooklyn walk becomes a crisp, hands-on lesson in why snow sticks, stacks, and insulates.

"Snow day!" sends Unexplainable out into Brooklyn after a heavy New York storm, where fresh snow turns Prospect Park into a small reporting assignment.

My brain made me do itMar 9, 2026

A brain scan becomes a question about blame, control, and how far evidence can reach.

Unexplainable turns a 1991 Manhattan case into something more uneasy than tidy true crime: a scan shows a cyst pressing on the frontal lobe, and the show keeps asking how much control a person really has when the brain itself is part of the argument.
