Circadian rhythms influence not only sleep and metabolism but also the ability of cancer cells to invade, survive in blood, and colonize distant organs. 

High-precision Global Navigation Satellite System (GNSS) positioning depends on successful carrier-phase ambiguity resolution, but this remains difficult in urban canyons, dense vegetation and other challenging environments. 

Researchers have identified a new tumor-suppressive circuit that controls stem-like behavior in hepatocellular carcinoma (HCC). 

A research team has developed a nickel-based catalyst that converts glucose into lactic acid, a building block for biodegradable plastics. 

A joint team from China has published a survey paper in National Science Review. The study reviews recent advances in EEG-based emotion recognition from an interdisciplinary neuroscience and information-science perspective and introduces EEGEmoLib, an open-source Python toolbox that integrates psychological and neuroscientific priors into algorithm design, offering a standardized platform with theoretical grounding and practical usability.

An ultrasound-responsive micronanorobot combines a collagenase-secreting bacterium, bismuth ferrite nanoparticles, the drug DM4 and a targeting ligand to treat nonmuscle-invasive bladder cancer. After intravesical delivery, it degrades tumor matrix, enhances drug penetration, and ultrasound triggers reactive oxygen species, achieving 90.8% cell death in vitro and 82.4% tumor inhibition in mice. The system also promotes antitumor immunity, increasing CD8+ T-cell infiltration and shifting macrophages toward the M1 phenotype.

Climate policy models usually assume people hold accurate beliefs about climate damages. A new study builds disinformation into a climate–economy model and finds that informed democratic majorities can deliver stronger carbon taxes than a politically constrained planner, but this advantage collapses abruptly once disinformation tips the majority. Late and persistent disinformation yields the most severe warming, while counter-disinformation efforts can largely restore effective policy.

A study published in the Journal of Bioresources and Bioproducts examines whether hydrophilic deep eutectic solvents (DESs) can provide a technically and economically viable alternative to conventional pre-hydrolysis Kraft pulping for dissolving pulp production. Using Aspen Plus process simulation together with techno-economic analysis, life-cycle assessment, sensitivity analysis and Monte Carlo uncertainty analysis, the researchers evaluated five process configurations at an industrially relevant scale. The results indicate comparable pulp yields, while revealing that DES recovery and energy consumption remain major barriers to competitiveness. A pre-hydrolysis-assisted configuration achieved the lowest modeled minimum selling price of 1,330 yuan per air-dry metric ton. The analysis also shows that economic and environmental performance do not necessarily favor the same process configuration.

A perspective published in the Journal of Bioresources and Bioproducts examines the emerging role of silk fibroin (SF)/polylactic acid (PLA) composite scaffolds in bone and related tissue regeneration. The review brings together evidence on material chemistry, scaffold architecture, interfacial bonding, degradation, mechanotransduction, osteogenesis, angiogenesis and immunomodulation. Rather than treating fabrication methods or biological responses separately, the authors discuss how these factors interact to determine scaffold performance. The review also assesses evidence across in vitro, animal and translational studies, concluding that substantial work remains before SF/PLA scaffolds can move toward human clinical applications.
