With their identification of negative velocity, scientists have made a physics-defying discovery about how cells move.

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 ...

Using a pioneering method they developed to directly measure viscosity in a group of cells, Associate Professor Jacob Notbohm and PhD student Molly McCord have made a surprising discovery that upends ...
