SHEMIM / Research
Research
SHEMIM studies breath and body scent as an honest, non-invasive signal of well-being. The work is organized as connected topic pages, and every claim is tagged for how settled it is: what the evidence supports, what is inference, what is still hypothesis.
-
Start here
Why scent?
The open questions that drive the work, from why we sniff our own hand to why receptors for smell line every organ. Each one tagged for how settled the evidence is.
-
The basics
How Smell Works
A few hundred receptors and a combinatorial code, rich enough to tell apart a near-infinite world of odors, and a signal that reaches the brain by an unusually direct route.
-
Life’s first language
The Oldest Sense
Before sight or hearing, living things read their world by chemistry. Smell is the most ancient sense: the one every kingdom of life still shares.
-
Scents as Medicine
The Molecular Sense
Scent is molecular recognition: the body reading its own chemistry through receptors found in every tissue we have looked at, and a growing frontier of medicine.
-
Reading what we exhale
The Breath as a Signal
Hundreds of molecules ride out on every exhale, a continuous, non-invasive readout of the body’s chemistry. One breath test is already routine medicine; most of the signal is still unread.
-
Smell beyond the nose
The Body-Wide Sense
The receptors the nose uses to read the world are scattered through every organ (kidney, heart, skin, gut, sperm) where they read the body’s own chemistry and act on it.
-
Whose scent is it?
Body Odor & Identity
Our scent is made by our microbes, tuned by a single gene, and shifting with age, diet and feeling: an honest, individual signature, even perfume cannot overwrite.
-
The Proust effect
Why Smell Triggers Memory
A passing scent can return us to childhood in an instant. Smell has an unusually direct line to the brain’s seats of emotion and memory, though the popular superlatives outrun the data.
-
Cues, not love potions
The Truth About Human Pheromones
Body odor carries real information about us, but no human "pheromone" has ever been validated, the vomeronasal organ is vestigial, and the sprays fail. The honest science of chemical communication.
-
When the nose goes quiet
What Smell Loss Reveals
Losing the sense of smell is one of the body’s earliest alarms: an early sign of Parkinson’s, Alzheimer’s and infection, and a strong predictor of mortality.
-
The body’s oldest alarm
Can You Smell Disease?
Some illness carries a literal smell, trained dogs catch cancer in a sample, and one breath test is already routine medicine. What the evidence supports about reading disease by scent, and its honest limits.
-
We are, a little, how we eat
Diet & Body Scent
Garlic reaches the skin, a non-meat week reads as more pleasant, and metabolism can turn food into odour. How diet changes our scent, and why "eat your way to smelling better" is mostly still inference.

The full framework
The Program
How the pieces connect: the structured body of frameworks SHEMIM is building in the open, organized as a knowledge graph rather than isolated studies.

Reference
Scent, Defined
Plain definitions of the terms behind the research: olfaction, the volatilome, chemosignals, anosmia, ABCC11, each linked to the page that explains it.
How we tag evidence
Across these pages a claim is Established (robust, peer-reviewed), Documented · early or Emerging (real but preliminary), or held openly as a hypothesis. We mark the difference rather than blur it, and we lead with the empirical core. SHEMIM is early-stage: conceptual architecture and research design, not yet pilots or published results.
