Now hear this: Simple fluid waveguide performs spectral analysis in a manner similar to the cochlea
(Phys.org) —Within the mammalian inner ear, or cochlea, a remarkable but and long-debated phenomenon occurs: As they move from the base of the cochlea to its apex, traveling fluid waves – that is, surface waves, in which ...

Studying a cell's crawling motion in a fluid
Cell motility, the spontaneous movement of cells from one location to another, plays a fundamental role in many biological processes, including immune responses and metastasis. Recent physics studies have gathered new evidence ...

Ubiquitous but overlooked, fluid is a source of muscle tension
Touch your toes. Feel that familiar tension in your leg muscles? A new Brown University study suggests that one source of the tension might be something that scientists have always known was in your muscle fibers, but never ...

Simplified model predicts patterns that form from honey-like fluids
Drizzling honey on toast can produce mesmerizing, meandering patterns, as the syrupy fluid ripples and coils in a sticky, golden thread. Dribbling paint on canvas can produce similarly serpentine loops and waves.

Toward a deeper understanding of turbulence in elastoviscoplastic fluids
Three-dimensional simulations shed light on how energy dissipates within non-Newtonian fluids (fluids in which viscosity depend on the shear rate.) The result is valuable in the context of disaster forecasting and the management ...

Revealing the mechanisms behind the enhancement of thermal properties of graphene nanofluids
Disperse graphene in a suitable solvent and the resulting nanofluid will have much better thermal properties than the original liquid. Three ICN2 research groups collaborated to describe and explain this effect from the inside ...

Researchers discover a way for temperature gradients in fluids to move objects
Researchers at MIT have discovered a new way of harnessing temperature gradients in fluids to propel objects. In the natural world, the mechanism may influence the motion of icebergs floating on the sea and rocks moving through ...

Anatomy of a superorganism: Ant pupae secrete fluid as 'milk' to nurture young larvae
Life in an ant colony is a symphony of subtle interactions between insects acting in concert, more like cells in tissue than independent organisms bunking in a colony. Now, researchers have discovered a previously unknown ...

Scientists identify key trends in high-energy-density mixing layers
Imagine a bottle of salad dressing containing oil and vinegar. The oil has a lower density than vinegar, so it floats on the vinegar. The oil will not stay trapped under the vinegar if the bottle is flipped upside down. It ...
