particle

Hantavirus refers to a strain of viruses carried by rodents, primarily transmitted to humans through inhalation of airborne particles from dried rodent droppings.

More than a century later, fine particles of pollution still clung to its feathers, dulling what once was a scarlet red breast to a mottled gray.

The combined “do not drink” and “do not boil” notice is for contaminants dangerous not only to ingest, but also to inhale as particles that can enter the air when boiled.

Also in California, a 2023 study found that each event that exposed residents to wildfire-associated tiny particles was associated with between 19 and 28% higher odds of a tuberculosis diagnosis within 6 months.

Specifically, it relies on so-called Majorana particles, which themselves were previously considered theoretical - work claiming that they had been discovered in 2018 had to be retracted.
