A new asymmetric non-fullerene acceptor, P2EH-1V, is designed and synthesized for constructing devices demonstrating record-high efficiencies of 26.7% (certified at 26.4%) over an aperture area greater than 1 cm² in perovskite–organic tandem solar cells.

Bacterial cytokinesis is driven by a multiprotein complex, the divisome, that is organized by the Z ring and responsible for septal cell wall synthesis. Here, Gong et al. show that septal cell wall synthesis facilitates Z-ring condensation, indicating that the divisome is a self-enhancing machine.

Partitioning of FtsN and the septal peptidoglycan synthesis complex between an active synthesis track and an inactive denuded glycan track coordinates opposing peptidoglycan synthesis and degradation activities in E. coli.

Bacterial protein FtsZ polymerizes at mid-cell and exhibits treadmilling dynamics, driving the movement of enzymes that synthesize septal peptidoglycan. Here, McCausland et al. combine theoretical modelling with single-molecule imaging of bacteria to show that FtsZ treadmilling drives enzyme movement via a Brownian ratchet mechanism.

Porous materials with high strength are desirable for many applications. Here, the authors present a supramolecular metallic foam enabled by nanostructured liquid metals connected with high-density metal-ligand coordination to exhibit ultrahigh specific strength and recyclability.

Pure CuInSe₂ solar cells suffer from strong interfacial carrier recombination. Here, the authors introduce a wide U-shaped double Ga grading with a minimum bandgap of 1.01 eV and achieve certified device efficiency of 20.26%, making it highly suitable for tandem solar cell applications.

Bacterial proteins are often recruited to specific subcellular locations to carry out their functions. Here, the authors use the optogenetic CRY2-CIB1 system to re-direct proteins to different subcellular locations, and thus manipulate the proteins’ functions, in live bacterial cells.

The fly male germline stem cells undergo asymmetric division, with old histones H3 and H4 preferentially retained in the daughter stem cell. The mechanisms that contribute to this outcome are revealed using super-resolution microscopy and DNA fiber analyses.

Recently, metal-organic framework materials have emerged as a promising platform for realizing molecular qubits. Here the authors study the role of phonons in spin relaxation within molecular qubit frameworks and show that hydrogen-bonded networks and their deuteration facilitate spin relaxation.

In this work, inorganic nanofillers are added to SEBS polymers to induce shearo-caloric effects, enhancing the elastocaloric response. Authors design and demonstrate a double-unit cooling device with a work recovery efficiency of 56.3% and a system coefficient of performance of 8.3.

Obtaining information about the structure of metal-organic layers (MOLs) using standard electron microscopy methods is challenging due to damage under electron beam irradiation. Here, the authors reveal a multistep formation process of MOLs and identify missing clusters, dislocations, loop and flat surface terminations and ligand connector of MOLs via complementary electron microscopy techniques.

Human somatic cells were reprogrammed to human chemically induced pluripotent stem cells that demonstrate key features of embryonic stem cells.

During replication stress, the RPA protein complex coats single-stranded DNA to preclude RAD51 loading. Here, the authors show how RPA and CST crosstalk to regulate RAD51 activity.

A recurrent ECSIT mutation in individuals with extranodal natural killer/T cell lymphoma induces NFκB in cancer cells, leading to macrophage activation, and associates with progression to fatal hemophagocytic syndrome. NFκB-targeting therapy produced stable remission in two patients.

We introduce a major scientific endeavour called π-HuB (proteomic navigator of the human body), its aim being to generate and harness multimodality proteomic datasets to enhance our understanding of human biology.

Self-healing materials hold great promise for applications in wearable electronics, artificial muscles and soft robots but selfhealing at subzero temperatures remains a great challenge. Here, the authors present a robust subzero healable glassy polymer by incorporating polyphenol nano-assemblies with a large number of end groups into polymerizable deep eutectic solvent elastomers.

FtsN promotes the inward synthesis of septal peptidoglycan (sPG) through the FtsWI complex during bacterial cell division. Here, Lyu et al. apply single-molecule microscopy on E. coli to show that FtsN proteins (I) move processively at a speed similar to that of FtsWI molecules. (II) can be divided into two populations based on their speeds, and (III) their movement is driven exclusively by peptidoglycan synthesis

Distance distribution correction (DDC) eliminates repeat localizations caused by fluorophore blinking without the need for calibrations. Use of DDC yields accurate and quantifiable single-molecule localization microscopy data.

Single-molecule tracking of the septal peptidoglycan glycosyltransferase FtsW reveals two populations: a fast-moving one that follows treadmilling FtsZ and a slow-moving one that is involved in peptidoglycan synthesis.

The precise role of auditory cortical and thalamic projections in the representation of sound in the auditory striatum is not known. Here, the authors show that silencing thalamic inputs lowers the gain of sound-evoked responses while cortical inputs only affect the best frequency responses of striatal neurons.

New fluorescent biosensors enable the first super-resolution imaging of enzyme activity in live cells via fluorescence fluctuation increase by contact (FLINC).

Upon stimuli, chloride intracellular channel CLIC3 is induced and mitigates intracellular chloride ion lose, thereby controls mitochondrial dysfunction, ROS accumulation, DNA damage, and fibroblast cellular senescence by interacting with ERK7.

Ultracold atomic gases in optical lattices potentially offer simulations of condensed-matter phenomena beyond what theory and computations can access; compensated optical lattice techniques applied to the Hubbard model now enable unprecedented low temperatures to be reached for fermions — only 1.4 times that of the antiferromagnetic phase transition, approaching the limits of present modelling techniques.
