'Negative Viscosity' Helps Propel Groups of Migrating Cells, Study Finds

Cells can generate negative viscosity to propel movement

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 other.
