  • A futuristic method of data storage depends on the 'write–read' action of a multitude of tiny silicon tips. The concept of dynamic superlubricity offers a way to avoid the wear that would otherwise cripple them.

  • Is friction dominated by electrons or by lattice vibrations? A nano-contact experiment shows that on a Nb surface friction drops by a factor of three when crossing the superconductivity transition, showing that it has essentially an electronic nature in the metallic state, whereas the phononic contribution dominates in the superconducting state.

  • Simulations of nanoscale sharp tips sliding on a salt surface predict vanishing friction at temperatures close to the melting temperature, as the tip skates on a layer of liquefied salt. This insight opens the way to applications in MEMS, NEMS and auto/aerospace engines.

  • Cryo-electron microscopy can determine the structure but not the nanomechanics of biological matter. Here the authors combine force spectroscopy in cryogenic conditions with computer simulations to characterize the properties of DNA simultaneously down to the sub-nm level.
