A new study introduces a factor graph optimization (FGO) framework for integrated Global Navigation Satellite System (GNSS)/Low Earth Orbit (LEO) precise point positioning (PPP). 

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

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.
