Phoebe Lark writes about the biology and chemistry your body and home would rather you didn't examine too closely — odors, fluids, microbes, parasites, infestations, and the quietly industrious rot happening on and around you right now. She follows disgust down to the mechanism underneath, where the gross thing almost always turns out to be a system doing exactly what it evolved to do.
DNA Genealogy Solved a 39-Year-Old Sex Crime—Two Days Too Late
Forensic genealogy just closed a 39-year-old kidnapping and sexual assault—but the man charged died before investigators could reach his door.
Nature's Nesting Doll of Infection Goes Three Layers Deep in Borneo
Scientists just found a new fungus in Borneo that doesn't bother hijacking ant brains — it just feeds on the fungus that's already doing it.
Why the Drug That Finally Beat KRAS Took 40 Years to Arrive
For decades, a single mutant gene drove some of the deadliest lung cancers while resisting every drug thrown at it — now a head-to-head trial has shown that the second wave of treatments may be genuinely different, not just incrementally better.
Why a Parasitic Bug Turned Your Sleep into Its Delivery System
Chagas disease doesn't kill you loudly — it colonizes your heart in silence, and the bug that delivers it has a deeply unsettling feeding strategy.
Why Rats Recoil From Sick Companions Before Showing Any Symptoms
Rodent research is revealing that disgust isn't a feeling so much as an ancient pathogen-detection engine running on smell.
The Slime You Scrubbed Off the Drain Came Back. That's the Point.
New research shows that household cleaning kills the bacteria inside a biofilm while leaving its scaffold intact — which means the colony doesn't die, it just takes a short nap.
What Environmental DNA Found (and Didn't) in Loch Ness
Environmental DNA sampling can find a single organism's genetic trace in millions of liters of water — which makes what it didn't find in Loch Ness the more interesting result.
The Microbes in Your Gut Are Deciding What Your Skin Does Next
A 2025 review confirmed the gut-skin axis runs in both directions — and the signaling mechanism is stranger, more specific, and more actionable than the probiotic aisle ever let on.
Your Breath Is a Readout of Your Gut Microbiome. Scientists Just Proved It.
A 2025 Cell Metabolism study confirmed what scientists suspected for years: the microbial fermentation churning through your gut is chemically leaking into your breath — and that volatile signature might be the future of gut diagnostics.
Your Gym Clothes Smell Worse the More You Wash Them — Here's the Chemistry
Synthetic athletic fabric doesn't just trap body odor — it selectively breeds the bacteria responsible for it, turning every wash cycle into a missed opportunity.
Decomposition Has a Smell for Every Stage — And Science Is Finally Mapping It
The odor rising from a decomposing body isn't a single stench — it's a shifting chemical record written by bacteria, and forensic scientists are learning to read it like a clock.
The Mites Living on Your Face Aren't the Problem. Their Bacteria Might Be.
Demodex mites graze on your face sebum around the clock, but new research suggests the bacteria living inside them — not the mites themselves — may be quietly inflaming your skin.
Why Disgusting Smells Outlast Pleasant Ones Every Single Time
The reason a rotting smell colonizes your upholstery while fresh coffee vanishes in minutes has nothing to do with how strong the odor is — it has everything to do with what the molecule actually wants to do.
Indoor Mold's Real Threat Isn't the Stain — It's the Air Around It
A new method for detecting airborne mycotoxins confirms what the stain on your wall can't tell you: the toxic part already left.
