Measurements of physiological and geometrical parameters of the sieve tube system in Ipomoea nil provide strong support for pressure driven mass flow.

Fish in the thrust wake of a flapping foil reduce tail-beat frequencies, synchronize with oncoming vortices, and swim energetically more efficiently.

Unraveling the ultrafast polar tube ejection in microsporidia reveals extreme cellular hydraulics, providing a data-driven model for infectious cargo transport, with implications for physical approaches to understanding microsporidia transmission.

A new tracer infusion method is used to confirm that pulsatile cerebrospinal fluid transport into the brain occurs naturally and is driven by the cardiac cycle, not by tracer injection.

SWELL1 is required for basal, stretch, and flow-mediated endothelial AKT-eNOS signaling in vitro and protects against angiotensin-induced hypertension and diabetes-associated vascular dysfunction in vivo.

Perception is proposed to be a dynamic motor-sensory closed-loop process in which information flows through the environment and the brain in continuous loops, converging towards steady-state percepts.

The pre-Bötzinger complex, known as the kernel for the breathing generation, consists of separate subpopulations of neurons that project to specific nuclei to coordinate respiratory rhythmicity with different physiological behaviors, such as nasofacial activity.

PKD2 (polycystin-2) channels are a major component of a flow-sensing signaling mechanism in endothelial cells that stimulates vasodilation and reduces blood pressure.

Radiotelemetric and genetic studies of peripheral tissue response show that a peripheral tissue can dynamically alter cardiovascular adaptation to changes in environmental oxygen.
