A paper released in the Journal of Bioresources and Bioproducts describes a fully bio-based barrier film that outperforms PET and PE in oxygen blocking while carrying an integrated curcumin indicator. Dialdehyde nanocellulose (DCNF) generated by 1 h periodate oxidation is blended 75% with pristine cellulose nanofibres; vacuum filtration builds a self-cross-linked sheet that is then dip-coated with an ethyl-cellulose/curcumin solution. The resulting 40 g m-2 membrane transmits 79% visible light yet transmits only 6.9 cm3 m-2 d-1 O2 (120-fold improvement over unmodified CNF) and 43 g m-2 d-1 water vapor—comparable to commercial polypropylene. Over 500 min the composite scavenges 91% DPPH radicals and suppresses > 99.9% growth of E. coli and S. aureus. When attached to refrigerated shrimp, the yellow label turns orange-brown as volatilised amines raise local pH, giving an irreversible but easy-to-see spoilage alert within 2 d. The approach requires no metals or synthetic antioxidants, making it a candidate for home-compostable, intelligent food packaging.

A study published online in the Journal of Bioresources and Bioproducts describes a single-step benzoylation protocol that converts UV-prone kenaf into a self-photobleaching, radical-quenching biobased reinforcement. After proving esterification and partial delignification with FT-IR, NMR and TGA, the team exposed modified and raw fibers to 300–400 nm light for 500 h. While untreated kenaf yellowed and lost 96 % of its tensile strength, the stabilized benzoylated variant first whitened as surface micro-cracks scattered light, then retained 65 % of original strength with no further color shift. Density-functional calculations show benzoyl substitution raises the hydrogen-abstraction barrier of lignin phenolics by ~20 kcal mol⁻¹, suppressing the semiquinone radicals that normally propagate oxidation. The approach needs only commodity reagents and existing pulp equipment, offering automotive, textile and packaging industries a scalable route to durable, naturally derived composites.

Infants born with Robin sequence often experience breathing and feeding difficulties caused by an underdeveloped lower jaw.

Developing effective, versatile, and high-precision sensing interfaces remains a crucial challenge in human–machine–environment interaction applications. Despite progress in interaction-oriented sensing skins, limitations remain in unit-level reconfiguration, multiaxial force and motion sensing, and robust operation across dynamically changing or irregular surfaces. Herein, we develop a reconfigurable omnidirectional triboelectric whisker sensor array (RO-TWSA) comprising multiple sensing units that integrate a triboelectric whisker structure (TWS) with an untethered hydro-sealing vacuum sucker (UHSVS), enabling reversibly portable deployment and omnidirectional perception across diverse surfaces. Using a simple dual-triangular electrode layout paired with MXene/silicone nanocomposite dielectric layer, the sensor unit achieves precise omnidirectional force and motion sensing with a detection threshold as low as 0.024 N and an angular resolution of 5°, while the UHSVS provides reliable and reversible multi-surface anchoring for the sensor units by involving a newly designed hydrogel combining high mechanical robustness and superior water absorption. Extensive experiments demonstrate the effectiveness of RO-TWSA across various interactive scenarios, including teleoperation, tactile diagnostics, and robotic autonomous exploration. Overall, RO-TWSA presents a versatile and high-resolution tactile interface, offering new avenues for intelligent perception and interaction in complex real-world environments.

To enhance the electrochemical performance of lithium-ion battery anodes with higher silicon content, it is essential to engineer their microstructure for better lithium-ion transport and mitigated volume change as well. Herein, we suggest an effective approach to control the micropore structure of silicon oxide (SiO_x)/artificial graphite (AG) composite electrodes using a perforated current collector. The electrode features a unique pore structure, where alternating high-porosity domains and low-porosity domains markedly reduce overall electrode resistance, leading to a 20% improvement in rate capability at a 5C-rate discharge condition. Using microstructure-resolved modeling and simulations, we demonstrate that the patterned micropore structure enhances lithium-ion transport, mitigating the electrolyte concentration gradient of lithium-ion. Additionally, perforating current collector with a chemical etching process increases the number of hydrogen bonding sites and enlarges the interface with the SiO_x/AG composite electrode, significantly improving adhesion strength. This, in turn, suppresses mechanical degradation and leads to a 50% higher capacity retention. Thus, regularly arranged micropore structure enabled by the perforated current collector successfully improves both rate capability and cycle life in SiO_x/AG composite electrodes, providing valuable insights into electrode engineering.

A new study published in Translational Exercise Biomedicine (ISSN: 2942-6812), an official partner journal of International Federation of Sports Medicine (FIMS), reveals that a progressive, multi-component exercise program, enhanced by wearable sensor technology, can significantly counteract the debilitating effects of frailty in older adults. The 12-week intervention led to remarkable improvements not only in physical strength and balance, but also in cognitive abilities and overall quality of life, presenting an effective and practical strategy for community health management in an aging global population.

Soft robots offer incredible potential in fields from medicine to exploration, but their fluid-driven actuators are often tethered to bulky, rigid pumps. Researchers from Zhejiang University have developed a new-type, soft fiber pump inspired by the body's lymphatic system. This pump is not only highly flexible and easy to manufacture but can also be powered by a built-in triboelectric nanogenerator (TENG), harvesting energy from motion to create untethered, self-sufficient soft robotic systems.

A model of a robot is crucial for controlling, but it is always hard to obtain for a new robot. Researchers from Sun Yat-sen University have introduced "NeRFSim," a novel framework that enables robots to autonomously construct their own morphological and kinematic models using only standard RGB images. The resulting self-model enables robots to accurately predict poses, solve inverse kinematic problems, and generate trajectories for task execution, providing a cost-effective and highly adaptive solution for robotic self-awareness.

A new study published in Life Metabolism reports that a single post-meal blood biomarker, 1-hour postprandial SPARC (SPARC-1H), can predict who will benefit most from adopting a Mediterranean diet. The discovery provides one of the clearest examples to date of how precision nutrition can identify individualized dietary responses using a simple blood test rather than complex multi-omics models.

Lung cancer is the leading cause of cancer-related mortality worldwide. Elucidating the molecular programs that enable tumor cells to evade regulated cell death and anti-tumor immune responses is essential for developing effective therapeutic strategies. In this study, Wang and colleagues employ a series of genetically engineered non-small cell lung cancer mouse models, high-throughput lipidomics assays, and functional perturbation experiments to uncover how tumor cells adapt metabolically to escape ferroptosis and reprogram the tumor microenvironment for CD8⁺ T cell dysfunction.
