At some point, most people have found themselves holding a tilted carton of milk or bottle of cooking oil, patiently waiting for the last drops to drip out. Now, physicists at Brown University have ...

Modeling the behavior of liquids is important for a wide range of applications, from industrial processes and medical devices to computer graphics and visual simulations. However, despite many years ...

Honey is already a pretty thick liquid, but let it begin to crystalize and it can become downright clumpy. The sugar crystals in suspension seem to increase its viscosity. This phenomenon occurs ...

When two fluids don't mix well, they sometimes form strange patterns called "viscous fingering," or Saffman-Taylor instability. Studying these patterns can help scientists understand how to design ...

Conventional wisdom holds that an electric current never returns to its source nor follows a circular path. Instead, it flows from one electrode to another following a local electric field, obeying ...

From cars on a highway to a viscous fluid like oil, our understanding of electron behaviour is being changed by new research. In high school science class, we learned that plugging a cable into an ...

Molecular assays necessitate accurate pipetting reagents and samples with a diverse set of properties — including viscous samples that can clog tips, distribute unevenly, and complicate ...
