Fundamental constants: a minimum value of viscosity has been calculated by Kostya Trachenko and Vadim Brazhkin (Courtesy: iStock/3quarks). Viscosity is an everyday phenomenon recognizable in the ...

In three spatial dimensions, it is a close relative of the quark-gluon plasma, the super-hot state of matter that hasn’t existed since the tiniest fraction of a second after the big bang that started ...

Researchers in the US claim that exposing a person to a magnetic field could reduce their risk of a heart attack by streamlining the flow of blood around their body. While the work currently remains ...

The cells in our bodies move in groups during biological processes such as wound healing and tissue development – but because of resistance, or viscosity, those cells can’t just neatly glide past each ...

Experiments show that swimming microorganisms can change a fluid’s viscosity. Not all of the effects can be explained by current theories. Moving along. E. coli bacteria propel themselves by pushing ...

The activity of sludge worms can alter the viscosity of a fluid, a finding that could help researchers understand active systems in cellular biology. Tipsy turvy. Sludge worms can perform as active ...

A noninvasive method measures the viscosity in a cell nucleus by observing the movement and fusion of cellular components. Cell portraits. A pair of nucleoli (red) inside a cell nucleus (green) move ...
