Bacteria can exploit a flagellar buckling instability to change direction
TLDR
High-speed video microscopy and mechanical stability theory now show that cells propelled with a single flagellum change direction with a flick-like motion that exploits a buckling instability.Abstract:
Buckling is often regarding as a form of mechanical failure to be avoided. High-speed video microscopy and mechanical stability theory now show, however, that bacteria use such processes to their advantage. Cells propelled with a single flagellum change direction with a flick-like motion that exploits a buckling instability.read more

Flagella-Driven Motility of Bacteria.
Shuichi Nakamura,Tohru Minamino +1 more
TL;DR: The current understanding of the structure and dynamics of the bacterial flagellum is described, which indicates that intracellular chemotactic signaling pathways regulate the direction of flagella-driven motility in response to changes in the environments, allowing bacteria to migrate towards more desirable environments for their survival.

The role of microorganisms in coral health, disease and evolution.
TL;DR: Generalization of the coral probiotic hypothesis has led to the hologenome theory of evolution, which proposes the occurrence of a dynamic relationship between symbiotic microorganisms and corals that selects for the coral holobiont that is best suited for the prevailing environmental conditions.
