From ketchup to quicksand, non-Newtonian fluids have long fascinated and puzzled scientists. Unlike ordinary fluids, their flow properties change depending on how much force is applied, but the ...

The Korea Institute of Civil Engineering and Building Technology (KICT) has developed a new cubic equation of state (EOS) that provides a physical justification for a mathematical structure that the ...

Researchers show how the judicious choice of fluid filler can suppress the turbulent flow that severely hinders the “top-kill” plugging of a blown-out oil well. Figure 1: (Top left) Kelvin-Helmholtz ...

A real-life forensic puzzle inspired researchers to explore the physics involved, and in Physics of Fluids, they present theoretical results revealing an interaction of the incoming vortex ring of ...

A fluid dynamics theory that violates causality would always generate paradoxical instabilities—a result that could guide the search for a theory for relativistic fluids. Figure 1: In Alice’s ...

Researchers demonstrate an active-fluid system whose behaviors map directly to predictions of the six-vertex model—an exactly solvable model that was originally developed to explain the behavior of ...

Egyptian fruit bats flew more slowly after eating alcohol-laced food. Now the urine strips that caught boozy wild chimps may be used on wild bats. Teen Heart Health Scores Average 68.3 in Ninth Grade ...

A connection between fluids containing self-propelling particles and the fundamentals of quantum mechanics has been discovered by Benjamin Loewe, Anton Souslov and Paul Goldbart at the Georgia ...

A study inspired by street performers making gigantic soap bubbles led to a discovery in fluid mechanics: Mixing different molecular sizes of polymers within a solution increases the ability of a thin ...

The knife easily leaves swirls in the spread. rimglow/iStock via Getty Images Plus Those Transportation Security Administration requirements are drilled into every frequent flyer’s head: You can carry ...
