When we cut our skin, groups of cells rush en masse to the site to heal the wound.
But the complicated mechanics of this collective cell movement — which are facilitated by rearrangements between each cell and its neighbors — have made it challenging for researchers to decipher what’s actually driving it.
Notbohm and doctoral student Aashrith Saraswathibhatla recently made a surprising discovery that sheds new light on how this collective cell migration happens. Through experiments, they found that the force each cell applies to the surface beneath it — in other words, traction — is the dominant physical factor that controls cell shape and motion as cells travel as a group.

Moving through traction.
Staying still through motion.
Living through death.
Dying through living.
Seek knowledge in the irrational. It is only there were knowledge is independent of any assumptions. And inside its chaos, you will find the peace you seek. For only in the irrational ideas are stripped of all their clothes. A the king can be really a king. Especially because he is naked.
Think. Via not-thinking.
How can you move, if not by your inability to do so?
How can you stand still, without others moving around you?
How can you be alive, if you weren’t dead?
