Verticalization of bacterial biofilms

Verticalization of bacterial biofilms, Published online: 18 June 2018; doi:10.1038/s41567-018-0170-4

Bacterial biofilms can transition from a surface-bound collective to form vertical clusters. The length-dependent mechanism revealed here triggers avalanches of cooperative reorientation that culminate in verticalization via an inverse domino effect.

Strong coupling between photons of two light fields mediated by one atom, Published online: 18 June 2018; doi:10.1038/s41567-018-0181-1

By coupling photons in two distinguishable modes to separate transitions of a single atom, strong correlations between photons are created. The technique makes all-optical switching and sensing possible at the single-photon level.
