Metagenomic environmental sampling of Rave bioaerosols

Bioaerosols are the little airborne leftovers of life: microbes, spores, virions, pollen, crumbs of tissue, and organic dust that we are always shedding from soils, water, buildings, and bodies. Ventilation and weather keep them moving, so they swirl through rooms and can travel far beyond them. Even when you cannot see anything “alive,” the traces stick around, suspended in air or tucked into dust, lint, and condensate.

Environmental metagenomics and eDNA take those traces seriously. You sequence the total genetic material from a messy sample and then use computation to tease out who might be there, and what they might be doing. Presence stops being a yes or no and becomes a gradient of molecular evidence.

In a lab, metagenomics wants repeatability: fixed volumes, controlled collection, calibrated gear. I am loosening that on purpose. A home dehumidifier is both tool and metaphor. It literally condenses the air we share into a reservoir, an archive of the room, turning dispersed bioaerosols into a single, readable liquid sample.

Condensation makes the whole chain visible: environment → water → sequence → data. It lets me sequence what is in the air, while making it obvious that “shared atmosphere” is something we make together, and something we can finally look at.
