Membraneless organelles (MLOs) formed through liquid-liquid phase separation (LLPS) constitute crucial dynamic microenvironments within cells, capable of selectively concentrating specific molecules and regulating biochemical reactions. Based on the working mechanisms of natural MLOs, researchers have designed and constructed various synthetic MLOs. These MLOs have been applied in regulating enzyme activity, optimizing metabolic pathways, regulating gene expression, producing recombinant proteins, and developing functional biomaterials. Here, we systematically summarized the design strategies, characterization techniques, and client protein recruitment methods for synthetic MLOs, and categorically reviewed their application progress in the biotechnology field. We also discussed current challenges faced in the practical applications of synthetic MLOs and future research directions. This review aims to provide theoretical guidance and practical reference for the design and application of LLPS-driven synthetic MLOs, thereby promoting their innovative development in synthetic biology and biotechnology.

The nucleotide-binding leucine-rich repeat protein (NLR) required for cell death (NRC) family represents a group of helper NLRs that are required by sensor NLRs to execute hypersensitive cell death during pathogen infection. NRCs contain an N-terminal coiled-coil (CC) domain essential for their function, yet our knowledge of how this domain contributes to NRC function remains limited. Using site-directed mutagenesis and transient expression in Nicotiana benthamiana, we screened conserved hydrophobic residues among NRCs and identified seven required for NRC4-mediated cell death, revealing a hydrophobic feature within the CC domain that contributes to NRC-mediated immunity. Structural analysis revealed that four of these residues form a hydrophobic core in the CC domain. This hydrophobic core is important for NRC4 subcellular localization, oligomerization, and phospholipid association, but not for NRC4 focal accumulation at the extrahaustorial membrane during Phytophthora infestans infection. Sequence analysis and functional assays revealed that this core is highly conserved in NRCs and some singleton NLRs but has degenerated in NRC-dependent sensor NLRs. Our study identifies a hydrophobic feature in the CC domain of NRCs and reveals its contribution to NLR-mediated immunity.

Electrification, including emerging technologies such as structural supercapacitors, is critical in realizing carbon-neutral transportation. A fundamental challenge is the trade-off between mechanical properties and energy storage capabilities. We report the fabrication of structural supercapacitors with a novel fibre-fibre interface to improve the interlaminar strength and encapsulation while considering the effect of structural resin on energy storage performance. The synthesized graphene nanoplatelets-modified electrodes attain a high specific surface area of ∼231 m<sup>2</sup> g<sup>−1</sup> - outperforming comparable carbon-based electrodes. We learned that the use of a gel-polymer electrolyte (GPE) separator containing 60 wt% Li-salt eliminates the requirement of electrolyte infusion and showed the highest values for conductivity for the cell produced using GPE. The implementation of glass fabrics (GFs) into the GPE improved the flexural modulus by ∼22%, while retaining the mechanical strength of the cells. The multifunctional performance of the produced SSCs were on par or even outperformed the performances of SSCs reported in literature. A proof-of-concept prototype demonstrates that gel-polymer electrolyte cells can retain charges for longer than those with a glass fibre separator. Cumulatively, these offer the possibility of conventional composite manufacturing techniques to scale-up and eliminate delamination issues arising from different thermal expansion coefficients which also addresses the balance between mechanical stability and electrochemical performance. Our findings support the advancement of durable, lightweight energy storage and delivery systems for sustainable transportation, with potential applications in robotics and wearable technologies.

Worming out defence strategies: mechanisms of immunity through the lens of genetic screens in C. elegans
, Heredity, Pages: 1-12, ISSN: 0018-067XSince Sydney Brenner's foundational work in 1974, Caenorhabditis elegans has served as an impactful model for biological discovery primarily driven by genetic approaches, including mutagenesis-based screens and RNAi-based functional genomics. We discuss here how genetic screens in C. elegans have advanced our understanding of innate immunity mechanisms by comparing signalling pathways and responses to a wide range of bacteria, viruses, and eukaryotic pathogens including oomycetes, and microsporidia. Screens have uncovered both evolutionarily conserved pathways and species-specific mechanisms of nematode immunity across multiple functional categories. These include mediators of pathogen recognition that specifically detect microbial patterns or infection-associated damage, surveillance immunity systems that sense pathogen-induced cellular dysfunction, and regulatory mechanisms that control the activation of immune signalling or balance it with physiological costs. A major theme emerging from these studies is the importance of cross tissue immune communication, as C. elegans coordinates responses between multiple tissues including neurons, intestine, and epidermis through complex signalling networks. Powerful genetic approaches, coupled with the continued development of new tools in the community, position C. elegans as an attractive whole-animal model for understanding fundamental principles of host-pathogen interactions and the evolutionary origins of innate immunity.

PromoterAtlas: decoding regulatory sequences across Gammaproteobacteria using a transformer model
, Nature Communications, ISSN: 2041-1723Recent advances in deep learning, particularly transformer architectures, have improved computational approaches for biological sequence analysis. Despite these advances, computational models for bacterial promoter prediction have remained limited by small datasets, species-specific training, and binary classification approaches rather than comprehensive annotation frameworks. We present PromoterAtlas, a 1.8M parameter transformer model trained on 9M regulatory sequences from 3,371 gammaproteobacterial species. The model demonstrates recognition of various regulatory elements across different species, including ribosomal binding sites, various types of bacterial promoters, transcription factor binding sites, and terminators. Using this model, we developed a whole-genome promoter annotation tool for Gammaproteobacteria, with various levels of validation that support the predictions of promoters associated with different sigma (σ) factors. Furthermore, we show that the model embeddings reflect cross-species evolutionary relationships, clustering promoters by σ factor identity rather than species-specific sequence features. Finally, we show that model embeddings encode regulatory sequence information that enables effective prediction of transcription and translation levels. PromoterAtlas can contribute to our understanding of and ability to engineer bacterial regulatory sequences with potential applications in bacterial biology, synthetic biology, and comparative genomics.

Autophagy is a conserved intracellular catabolic process, critical for plant stress tolerance. Upon their delivery in the vacuole, how autophagic bodies containing cargo are hydrolyzed to warrant autophagy degradation remains unclear in multicellular organisms. Here, we found that two Arabidopsis phospholipases, LCAT4 and LCAT3, traffic to the vacuolar lumen and converge on autophagic bodies through fundamentally different routes. While LCAT4 directly binds ATG8 and uses autophagy as a transport system to reach the vacuole prepackaged within autophagosomes, LCAT3 traffics to the lytic compartment independently of autophagosome formation. Knocking out both genes causes an accumulation of autophagic bodies accompanied with a reduction in autophagy degradation. In vivo reconstitution demonstrated that LCAT3 can hydrolyse the membrane of autophagic bodies, enabling the activity of LCAT4 to enhance this process. Together, this work sheds light on the vacuolar stages of autophagy, showing that plants have evolved a multi-component pathway for the efficient disruption of autophagosomal membranes as a critical step for the completion of the autophagy pathway.

Genotype-based drug development has yielded highly effective therapies, notably the triple combinations elexacaftor/tezacaftor/ivacaftor (ETI) and vanzacaftor/tezacaftor/deutivacaftor (VTD), now approved in Europe for people with CF having at least one non-class I variant. However not all these people with CF will respond to ETI or VTD, and a few not under the label may respond. Facilitating opportunities to access for patients with rare variants has required a shift in paradigm toward functional testing-based access. This approach assesses the potential benefit of modulator therapy using in vitro functional assays, either in engineered systems expressing defined CFTR variants (theratyping) or in patient-derived tissues (theranostics). We review theranostics as a critical tool for personalized medicine in CF, highlighting its validation in in vitro models derived from patients' own cells such as human intestinal organoids and human nasal epithelial cells. We discuss the current regulatory landscape regarding modulator approval and propose strategies for improving equitable access to effective treatments for all people with CF. Importantly, we advocate for functional assays to be accepted as standalone evidence of drug efficacy for patients with rare variants. Theranostic approaches remain critical when theratyping has not been achieved, and genetic data is not available or clearly interpretable. Indeed, theranostics has emerged as an essential pillar of CF drug access, complementing genotype-driven strategies. As the field advances, continued validation, standardization, and regulatory integration of in vitro functional assays will be key to ensuring that every person with CF-regardless of their genotype-has the opportunity to benefit from precision therapies.

A method to produce multifunctional structural battery composites comprising carbon fibre reinforced anodes and cathodes, and electrolyte filled bicontinuous polymer matrix is disclosed. Lithium iron phosphate (LFP) and lithium titanate (LTO) were deposited onto carbon fibres by electrophoretic deposition (EPD) to produce multifunctional cathodes and anodes, respectively. EPD allowed for an even coating of individual carbon fibres depositing 30 wt% of active materials with respect to carbon fibre current collectors. Carbon fibre reinforced cathode (LFP@CF), separator and anode (LTO@CF) were stacked and impregnated using polyethersulfone (PES) in N-methyl-2-pyrrolidone (NMP) solution; the PES was subsequently precipitated by non-solvent induced phase separation forming a porous high-performance polymer matrix within the stack. The porous matrix binds the carbon fibres and separator while providing sufficient openness for the electrochemical interface. The LFP@CF | separator | LTO@CF/PES assembly had an average Young's modulus of 27 ± 10 GPa and tensile strength of 282 ± 65 MPa. Structural battery composites possessed an energy density of 63 Wh/kg<inf>LFP</inf> or 2 Wh/kg<inf>battery</inf> at charge rate of 0.1C and were able to be cyclically dis/charged for more than 400 h.

β-Glucosidase (BGL) plays a key role in wine aroma enhancement by hydrolyzing glycosidic precursors; however, its application is limited by instability under harsh winemaking conditions. To address this, we developed an integrated biocatalytic system by immobilizing an acid-tolerant BGL onto functionalized magnetic oak chips (NFOak) via oriented Ni2+-histidine coordination. Comprehensive characterization confirmed the fabrication of a porous, magnetic cellulose scaffold. The immobilized BGL exhibited significantly enhanced stability against winemaking stresses (low pH, high ethanol) compared to the free enzyme. Furthermore, magnetic actuation of the biocomposite improved its hydrolytic performance, likely attributed to enhanced mass transfer. When applied to Chardonnay and Marselan wines, the magnetically actuated system effectively hydrolyzed glycosidic precursors, markedly increasing the concentrations of key volatile compounds-such as linalool and ethyl benzoate associated with fruity and floral aroma profiles. The treatment also induced subtle modulations in wine color and phenolic composition. Safety assessments confirmed no nickel leaching and oenologically acceptable iron levels. This work provides a sustainable and efficient strategy for controllable aroma modulation, combining the oenological benefits of a natural oak carrier with the operational controllability of magnetic actuation.
