The interface between a quantum Hall state and a superconductor hosts topological modes. Here, interference between two such modes turns an electron into either a hole or an electron depending on the phase difference along the interference path.

The intrinsic dipole moment of 228Th is reported, from which the degree of the nucleus’s octupole deformation is estimated, suggesting that 229Th and 229Pa may be suitable candidates for the search for a permanent atomic electric dipole moment.

Symmetry breaking is essential for polarization of cells and generation of left–right body asymmetry. Here the authors investigate the arrangement of hair cells in zebrafish and show that mirror-symmetric patterns arise from a combination of biochemical and mechanical symmetry-breaking events.
