Every year, billions of tons of dust is whipped up into the atmosphere—carrying more than just particles. These dust clouds transport bacteria and fungi around the world. Recent research shows that Bacillus bacteria may survive dust storms not only by forming spores, but also by building biofilms—protective communities that help them grow and persist in harsh conditions. In lab experiments, dust-associated Bacillus isolates formed biofilms under conditions associated with dust storms, like high
