Summary

Story summary

Research from Saarland University challenges the belief that pressure and friction cause ice to be slippery.
It identifies molecular dipole interactions between ice and shoe soles as the true cause of slipperiness.
This finding overturns a 200-year-old paradigm established by James Thompson.
Dipole interactions can create a liquid film on ice, even near absolute zero.
The study, published in Physical Review Letters, impacts ice dynamics and winter sports.
