You Are Surrounded by an Invisible Dirt Aura Everywhere You Go
Recently, a team from Stanford University did a study on a swarm of chemicals, microbial life forms, and bugs that seems to surround every human being. Published in the journal Cell, the term assigned to this phenomenon is the exposome: the exposome is what you smell when you pass by another person and they have a certain odor.
People just have a certain set of bacteria strains that cover their body, and produce certain chemicals that add to their natural scent. Some people have a different hormonal composition than other individuals, some people wear cologne, there are all kinds of factors that influence this “exposome,” aura thing if you think about it. According to Science Alert:
“If you ever feel truly, utterly alone, take heart: an invisible entourage never leaves your side. This hidden, ever-present swarm is called the exposome, and while scientists have only just begun to figure out what populates this constant cloud of chemicals, bugs, and whatnot swirling around you, new research offers an unprecedented glimpse inside.”
That’s right: you have a dirt aura.
Stanford University geneticist Michael Snyder and his team decided to conduct the experiment by re-engineering a small device to monitor air. The device is about the size of a pack of ordinary playing cards. Over the course of a couple years, a little over a dozen engineers, fifteen people had these units strapped to their arms for different periods of time.
The little playing card deck sized things collected puffs of air consistently from the environment surrounding the individuals for periods of time ranging from one week to two years, from the “personal orbit” and “exposome” of the subjects and whatever else came into it. The lead researcher wore it for two years, the rest for a week or a month.
“People have measured things like air pollution on a broad scale, but no one has really measured biological and chemical exposures at a personal level,” said Michael Snyder.
“No one really knows how vast the human exposome is or what kinds of things are in there.”
So all kinds of particulates were inhaled into the devices, ranging from chemicals, to bacteria, viruses, and fungi. One would wonder how many toxic chemicals or heavy metals were inhaled by the devices as well.
The DNA and RNA of things captured by the devices were extracted for sequencing, and the particulates were chemically profiled for a unique, customized database.
“Scientists had assembled separate bacteria, viral or fungi databases, but to fully decode our environmental exposures, we built a pan-domain database to cover more than 40,000 species,” said team member Chao Jiang.
The study’s participants all spent time across somewhere around 50 locations in the San Francisco Bay Area.
What did they find? Their personal exposome composition were mostly individual. That means that people have a resilient, consistent exposome, aura of smells and chemicals and particles and bacteria, that remains kind of your own no matter where you are.
“It turns out, even at very close distances, we have very different exposure profiles or ‘signatures,'” Snyder said.
“The bottom line is that we all have our own microbiome cloud that we’re schlepping around and spewing out.”
Continuing from Science Alert:
“What makes up each person’s crowd is of course variable then, but includes numerous traces of their own microbial cloud, plus things like fungi, and particles that have floated in from their immediate environment – such as household pets, chemicals, plants, and so on.
The researchers acknowledge this is only the beginning of this kind of research. In their study, only three individuals wore the device extensively, so there’s a limit to how much we can rely upon their results so far.”
The mainstream media which gravitates toward scientism and extreme left brain thinking can appreciate this, a dirt aura: but get metaphysical and they won’t appreciate that at all.
