Cold self-lubrication of sliding ice
Imagine a perfectly neat stack of playing cards representing the frozen, solid ice. The old theory said you needed to add heat (friction) to 'melt' the cards and make them messy and slidable. This new research says you don't need heat at all. Just by pushing the top of the stack sideways (sliding), you can jumble up the top few cards, creating a disordered, slippery layer. The ice isn't technically melting; it's being mechanically disorganized into a self-lubricating state.
