Summary: The passage discusses the similar organization of biomaterials made by living systems and the growing interest in engineered living materials (ELMs) with tailored functions. It highlights the technologies still missing from the field of ELMs, such as designing novel matrix elements, producing and incorporating biominerals, and improving critical material properties. Overcoming these challenges will bring us closer to unlocking the potential and versatility of biomaterials in creating designer ELMs.

Summary: A curvature-sensing mechanism mediated by the BAR domain protein Snx33 is identified in immune-like cells for obstacle evasion. Actin polymerization at the leading edge of migrating cells is inhibited by Snx33 in regions with inward plasma membrane curvature. Genetic perturbation of this machinery reduces cells' ability to evade obstacles and increases their speed and persistence in obstacle-free environments. This study reveals how cells interpret their environment using actin and plasma membrane biophysics.

Summary: Increased control of biological growth and form is crucial for transformative medical advances, but gaps remain in our understanding of meso-scale rules of morphogenesis. The engineering approach of creating novel synthetic living forms extends available model systems and is essential for the next generation of synthetic biology. Emphasizing emergent self-organization, tissue-level guided self-assembly, and active functionality will greatly increase our understanding of evolutionary developmental and cell biology.

Summary: By altering the reaction ratio of precursor Ir-2(ppy)(4)Cl-2 and bridging ligand of 4,4-bipyridine (bpy), a series of phosphorescent cyclometalated iridium(III) complexes of mono-, di-, and tetranuclear have been successfully obtained and characterized for the first time. The dissociation of bpy ligand can be accelerated by light irradiation or placing these complexes in glutathione (GSH) abundant aqueous solution, bpy releasing rate follows the order Ir1 > Ir2 > Ir3 > Ir4, and with an addition of histidine, a significant blue shift from orange to green phosphorescence was observed. Furthermore, the cellular dissociation of bpy can be monitored by an orange-to-green phosphorescent blue shift, and the translocation of Ir complexes from cytoplasm to nucleus can be observed within 4 h in living cells through confocal imaging. Additionally, the changes of cellular phosphorescence intensity recorded by flow cytometry reflect different speed of bpy release in human normal and cancer cells. Moreover, the iridium complexes exert significant anticancer effect in the dark with low photocytotoxicity, inducing reactive oxygen species generation, mitochondrial membrane potential depletion, and interacting with biomolecules, ultimately leading to late apoptosis of Hela cell.

Summary: This study used single-cell fluorescence imaging to investigate the effects of the β-defensin AvBD103b on living E. coli at physiological salt concentrations. The results provide key parameters for understanding the mechanism of action. The study found that AvBD103b interacts non-specifically with various polyanionic targets after penetrating the cell membranes, leading to cell death.

Summary: VGLUTs play a dual role in neurons by filling synaptic vesicles with glutamate and regulating intracellular Pi levels through transport activity. Studies have shown that VGLUT-mediated Pi influx is counteracted by Pi efflux, highlighting the importance of VGLUTs in both glutamate loading and Pi restoration.

Summary: Proteins driving membrane fusion must overcome energy barriers to induce intermediate steps where lipid bilayers' integrity is lost. The metastable intermediate preceding hemifusion does not require but is enhanced by divalent cations, characterized by the absence of proteins and local membrane thickening, induced by lipid rearrangements due to dehydration of the membrane surface revealed by simulations.
