  • The rice Lsi1 aquaporin mediates uptake of silicic acid via the roots. Here the authors show the crystal structure of rice Lsi1 and characterize a unique five residue hydrophilic selectivity filter providing a structural basis for the highly selective activity of Lsi1 in Si uptake.

  • Shoot-Silicon-Signal (OsFTL12) protein is expressed only in the rice shoot response to Si deficiency. Yet, the protein is also detected in phloem sap and root, stimulating the root Si uptake. This signal integrates shoot Si demand and root Si uptake.

  • Serial femtosecond crystallography reveals the structural dynamics of photosystem II during the S-state transitions that produce dioxygen, providing insight into electron transfer, water insertion, proton release and O–O bond formation on sub-microsecond timescales.

  • The main components of tight junctions (TJ) are claudins that polymerize and form meshwork architectures called TJ strands. Here the authors present the 3.6 Å crystal structure of murine claudin-3 and show that residue P134 causes a bending of the third transmembrane helix which affects the morphology and adhesiveness of the TJ strands.

  • The brain stores memories through a set of neurons known as engram cells. Here, the authors show that engram cells in the mouse hippocampus are organized into sub-ensembles representing distinct pieces of information, which are then orchestrated to constitute an entire memory.
