A new FRET-based cAMP biosensor with nanomolar sensitivity makes it possible to measure cAMP dynamics in miniscule subcellular compartments like cilia and flagella.

During intraflagellar transport (IFT), kinesin-II dissociates from IFT trains at the flagellar tip and its diffusion in flagella serves as a negative feedback mechanism that facilitates flagellar length control in Chlamydomonas.

Cryo-electron microscopy reveals previously undescribed structural features of choanoflagellate flagella and provides new insights into flagellar evolution.

In the microbe Chlamydomonas reinhardtii, a disassembly rate which depends on flagellar length provides an effective method to regulate the length of its two flagella.

A model for flagellar length control based on calcium influx is rejected based on quantitative measurements in Chlamydomonas cells.

The architecture of flagellated chambers in sponge pumps is linked to that of body plan, supporting the current view that the sponge aquiferous system evolved from an open-type filtration system.

The self-organised beat of cilia and flagella is dynamically regulated by curvature.

Both beneficial and pathogenic bacteria can use their sheathed flagella during host colonization as a novel toxin-/signal-delivery mechanism.

A small GTPase within the flagellum can participate in the control of transport from the base to the tip of the flagellum, and back again.

Prokaryotic and eukaryotic flagella follow a common trend in swimming cost-effectiveness, but eukaryotic flagella are too large for cells with prokaryote volumes, yielding insight into flagellar dissimilarity between taxa.
