"Microgravity's Mutational Boost: Bacteria Become Rapid Breeders"

Certain bacteria can mutate and reproduce more quickly when exposed to microgravity, as observed in a study on Escherichia coli cells. These bacteria picked up at least 16 genetic mutations and grew about three times as many colonies as unmodified bacteria. Even when removed from microgravity conditions, the growth advantage was retained, suggesting permanent genomic changes. While the reasons for this response are unclear, scientists are studying ways to protect astronauts and mitigate potential damage from space-modified bacteria. The mutated bacteria were found to be susceptible to antibiotics, providing temporary relief from a potential supercharged bacteria invasion.
