Active wetting of epithelial tissues

Active wetting of epithelial tissues, Published online: 24 September 2018; doi:10.1038/s41567-018-0279-5

An analogy with wetting has proven apt for describing how groups of cells spread on a substrate. But cells are active: they polarize, generate forces and adhere to their surroundings. Experiments now find agreement with an active update to the theory.

Multiple topological states in iron-based superconductors

Multiple topological states in iron-based superconductors, Published online: 24 September 2018; doi:10.1038/s41567-018-0280-z

Multiple different types of topological states are observed in iron-based high-temperature superconductors. This suggests that these may be a good place to try and engineer high-temperature topological superconductivity.

Many microorganisms use light-sensitive receptors to migrate. A case in point is the microalga Euglena gracilis, which avoids light intensity increases by swimming in polygonal trajectories — providing an elegant solution to navigational challenges.

A single-celled organism exhibits complex swimming behaviours in response to changes in light intensity. Modelling and experiments suggest that the swimmer exploits phase relations between its photoreceptor and orientation to enable navigation.

Wetting by living tissues, Published online: 24 September 2018; doi:10.1038/s41567-018-0316-4

An active counterpart to passive wetting is an encouraging sign for tissue physics and, more egenerally, the interface between biology and physics.

Are there limits to the applicability of textbook quantum theory? Experiments haven’t found any yet, but a new theoretical analysis shows that treating your colleagues as quantum systems might be a step too far.

Membrane-induced hydroelastic migration of a particle surfing its own wave, Published online: 17 September 2018; doi:10.1038/s41567-018-0272-z

A rigid particle moving along a soft wall feels a repulsive force that can reduce its drag. Evidence now suggests that for thin enough walls the particle can be displaced appreciably—a finding that may have implications for biological membranes.

Visualization of the periodic modulation of Cooper pairing in a cuprate superconductor, Published online: 17 September 2018; doi:10.1038/s41567-018-0276-8

A periodic pattern of Cooper pairs is observed at the atomic scale and is shown to be correlated with the local strength of the superconductivity. This reveals a new interplay between different ordered states in the cuprates.

Collective mechanical adaptation of honeybee swarms, Published online: 17 September 2018; doi:10.1038/s41567-018-0262-1

Suspended clusters of honeybees withstand dynamic mechanical forcing from their environment. Experiments and simulations suggest that collective stability relies on individual bees responding to local variations in strain.

Large-scale quantum computations are hampered by the propagation of errors. Experiments have now demonstrated the deterministic teleportation of a quantum gate, which prevents error propagation by using a combination of quantum and classical bits.

3D field phase-space control in tokamak plasmas, Published online: 10 September 2018; doi:10.1038/s41567-018-0268-8

A theoretical and numerical approach, validated by experiments at the KSTAR facility, shows how magnetohydrodynamic instabilities in tokamak plasmas can be efficiently controlled by a small relaxation of the confining field into a 3D configuration.

Water drops placed at rest on flat, hot solids are found to rotate and spontaneously propel themselves in the direction of their rotation. The effect is due to symmetry breaking of the flow inside the drop, which couples rotation to translation.

The axial symmetry of tokamaks benefits plasma confinement but hinders control. Experiments have now proven that optimized non-axisymmetric magnetic fields can provide much improved control without degrading the plasma confinement.

Driven-dissipative non-equilibrium Bose–Einstein condensation of less than ten photons, Published online: 10 September 2018; doi:10.1038/s41567-018-0270-1

Non-equilibrium Bose–Einstein condensation of 7 ± 2 photons is observed in a sculpted dye-filled microcavity. The small number of particles allows the authors to access and characterize the non-equilibrium dynamics of the bosonic modes.

Topolectrical-circuit realization of topological corner modes, Published online: 04 September 2018; doi:10.1038/s41567-018-0246-1

The realization of a two-dimensional quadrupole topological insulator—featuring gapless corner states but an otherwise insulating bulk and edge—establishes electrical circuits as a versatile platform for implementing topological band structures.
