  • This study measures 'puddles' of charge in a fractional quantum Hall device and finds new evidence for the existence of quarter charge particles, thereby boosting confidence in the prospects for topological quantum computation.

  • In most electrical conductors, heat is transported by charge carriers and so both usually flow in the same direction; but in two-dimensional electron systems subject to strong magnetic fields, certain fractional quantum Hall states can cause charge and heat to flow in opposite directions.

  • New approaches to integrate high-dimensional recordings of brain activity with single-neuron resolution with simultaneous recordings of natural animal behaviour enable the study of brain-wide activity in small animals including worms, flies and fish during behaviours and decision-making. This Review surveys experimental and theoretical approaches that have opened this area of systems neuroscience.
