  • Some types of fish can change color by modifying their intracellular guanine crystal in response to external stimuli. Here, Sano et al. mimic this effect in a dilute aqueous dispersion containing titanate nanosheets, whose interlayer distance is tunable to match the entire visible light spectrum.

  • Channelrhodopsins are light-gated ion channels for optogenetics. Here, authors report the 2.7 Å cryo-EM structure of a blue-shifted channelrhodopsin from Klebsormidium nitens, revealing a 6-s-cis retinal configuration and unique C-terminal modulation.

  • Light stimuli are widely used to control material properties, yet it remains challenging to reversibly photocontrol the dielectric permittivity. Nishikawa et al. achieve this goal in an anisotropic fluid via its liquid crystal phase transition induced by isomerization of an azobenzene-tethered phototrigger.

  • Inorganic soft materials are an attractive concept but challenging to make. Here the authors have developed a hydrogel consisting of inorganic nanosheets (14 wt%) and water (86 wt%) that undergoes thermally induced reversible and abrupt changes in its internal structure and mechanical elasticity (23-fold).

  • Tiny movable components could generate macroscopic mechanical motion if precise coherent operation can be exerted simultaneously. Here, the authors demonstrate this by using 10^10 pieces of colloidally dispersed nanosheets to generate wave under non-equilibrium state.

  • Construction of hierarchical nanostructures is important in material science, but precise morphological control remains a challenge. Here, the authors report a one-pot in-situ initiation-growth process from a liquid crystalline block copolymer to precisely control the morphology and dimensions of hierarchical nanostructures.

  • Ferroelectric nematic liquid crystals are interesting due to their combined high polarizability, electro-optic activity, and fluidity. Here, the authors tune the ferroelectric nematic phase transition by mixing diastereomer molecules, investigating the role of clusters in the stabilization of the ferroelectric nematic phase.
