A multiplexed microfluidic device was developed to facilitate high-throughput screening of bacterial chemotaxis on a single chip and demonstrated across a range of microbes, chemostimulants, and chemical gradient conditions.

A hydrodynamic model of fish swimming in a channel predicts a critical flow speed for fish to successfully swim against a flow, unveiling a passive mechanism for rheotaxis to emerge without access to any sensory information.

An atomic model of the bacterial chemosensory array obtained through the synthesis of cryo-electron tomography and large-scale molecular-dynamics simulations reveals a new kinase conformation during signaling events.

A ClC chloride channel protein allows neurons to interpret both temporal resolution and intensity of sensory input, which thereby contributes to an experience-dependent navigation behavior.

The slope of the chemoattractant concentration gradient is a driving force for sperm chemotaxis, by coordinating the entrainment of information flow between sensing, signaling and motility.

Asymmetric forward and backward swimming speeds reveal that the rotational bias, and not reversal frequencies, is an appropriate measure of chemotaxis signaling in Helicobacter pylori..

Mammalian sperm subject to shear flow swim in upstream spirals along the walls bounding such flows, thereby demonstrating a robust mechanism for upstream navigation to the ovum.

Mechanistic insights show how treatment with apoA1 is anti-inflammatory by rapidly disrupting macrophage chemotaxis and monocyte recruitment.

The reconstruction of a sensorimotor pathway from the olfactory-sensory neurons down to the pre-motor system reveals a descending neuron that plays a critical role in the organization of larval chemotaxis.

Understudied atypical MAPK, ERK3 controls epithelial secretome and chemotaxis.
