Article Synopsis
- Directed cell migration is essential for immune responses, especially for neutrophils during tissue injury or infection, which is influenced by electric fields generated by skin disruption.
- A novel protein called Galvanin has been identified as crucial for neutrophils to change migration direction in response to electric fields, based on a CRISPR screen.
- Galvanin quickly moves to one side of the cell when exposed to an electric field, altering how neutrophils extend and retract, indicating it acts as a sensor that guides cell movement in response to electrical stimuli.

Atomically precise metal nanoclusters (NCs) have been deemed a new generation of photosensitizers for light harvesting on account of their quantum confinement effect, peculiar atom-stacking mode, and enriched catalytic active sites. Nonetheless, to date, precise charge modulation over metal NCs has still been challenging considering their ultra-short carrier lifetime and poor stability. In this work, we conceptually demonstrate the integration of metal NCs with MXene in transition metal chalcogenide (TMC) photosystems a progressive, exquisite, and elegant interface design to trigger tunable, precise and high-efficiency charge motion over metal NCs, stimulating a directional carrier transport pathway.

The conversion of CO into carbon-neutral fuels such as methane (CH) through selective photoreduction is highly sought after yet remains challenging due to the slow multistep proton-electron transfer processes and the formation of various C intermediates. This research highlights the cooperative interaction between Fe and Cu ions transitioning to Fe and Cu ions, enhancing the photocatalytic conversion of CO to methane. We introduce an S-scheme heterojunction photocatalyst, CuFeO/ZnInS, which demonstrates significant efficiency in CO methanation under light irradiation.

Ferroelectric nematic liquid crystals are a class of recently discovered fluid materials formed by highly polar molecules that spontaneously align along a common direction, giving rise to a macroscopic polarization . Since the polarization vector is locally collinear to the optical axis , the study of the spatial patterns of enables deducing the structure of . We have carried on such topological study on ferroelectric nematic droplets confined between two solid ferroelectric substrates both when the droplet is in equilibrium and during a jet-emission phase that takes place when the solid surfaces become sufficiently charged.
