  • Single-molecule 3D tracking is critical to understand macromolecular dynamics but achieving this at a sub-millisecond resolution remains challenging. Here the authors present a 3D tracking method based on cross-entropy minimization and the true excitation point spread function.

  • Bound entanglement is a particular class that is not distillable—that is, it cannot be converted into a pure maximally entangled state by means of local operations and classical communication. A four-qubit bound entangled state, or Smolin state, has now been created experimentally.

  • Single-molecule fluorescence resonance energy transfer and real-time confocal laser tracking with fluorescence correlation spectroscopy together characterize how individual lac repressor molecules bypass operator sites while exploring the DNA surface at microsecond timescales.

  • Super-resolution localization microscopy produces biophysical information in the form of estimated positions of single molecules. Here, Lindénet al. estimate the uncertainty of single localizations, and show that this additional information can improve data analysis and localization precision.
