Places like hospitals or offices could stand to benefit, for example.Īnother potential real-world application for microbial cloud research is forensics. If we know there's an airborne disease risk, maybe we could develop ventilation accordingly," says Meadow. "We could potentially design our buildings around that. Understanding the interplay between the microbial cloud and environment could form the basis for attempts to better engineer indoor spaces to prevent the transmission of diseases. "Even just sitting at your desk, your cloud is probably reaching to your neighbor." The tiniest bacteria can be picked up and stay in the air for hours," he says. If there's any little bit of movement, they can just float around the room indefinitely. But for something that tiny, air is more like water. "We can only feel air when it's hitting us. How far the cloud reaches is all dependent on the "viscosity of the air," according to Meadow. The size of your cloud will have to do, in part, with how hot or cold your body temperature is at the moment. Your breath, which is part of your microbiome, is also hot and can push particles out too. Heat rises off the body, propelling the particles outward. In large part, you can thank your body heat for generating your unique microbial cloud. IMAGE CREATED BY VIPUTHESHWAR SITARAMAN, OF DRAW SCIENCE We didn't expect to be able to tell people apart," Meadow says. "This was a first stab at it to see if it was possible. "Each occupant's personalized airborne signal can be statistically differentiated from other occupants," they wrote. What's more, after three people spent four hours in a room together, giving off their microbes into the air and onto surfaces, Meadow's team was able to distinguish each person based just on the bacteria in the surrounding air. They determined that an occupied room is microbially distinct from an unoccupied one. In it, he and his research partners sampled the air surrounding 11 different people in a sanitized experimental room and sequenced the microbes emanating from them. On Tuesday, Meadow and his colleagues published a paper written while he was a postdoctoral researcher at the University of Oregon.

I have a beard when I scratch it, I'm releasing a little plume into the air. (All sorts of people, places and things can have their own microbiomes.) "We give off a million biological particles from our body every hour as we move around. "You know the dirty kid from Peanuts? Pig-Pen? It turns out we all look like that," says James Meadow, a data scientist at Phylagen, a company in San Francisco that focuses on improving the health of the indoor microbiome in places like hospitals and homes. And researchers are learning to be able to identify you by it.
REDDIT SITTING ON CLOUDS SKIN
In short, you have an aura, except it isn't made of purplish light it's your personal cloud of dead skin cells, fungus and many, many microbes. It hovers in a cloud around your body and leaves bits of itself on surfaces wherever you go. But within microbiome research is a brand-new field that is just beginning to understand a stunning fact: Your microbiome extends beyond yourself, into the air around you. This living layer is part of what's called the human microbiome-the collective genomes of all the "foreign" microorganisms that live in the human body-and research on it has exploded in recent years. From the perspective of these tiny organisms, the surface of your body is their living, breathing habitat.
