Biomimetic mRNA delivery system boosts precision immunotherapy for colorectal cancer
Science China PressPeer-Reviewed Publication
Researchers have developed a biomimetic mRNA delivery system that enhances the efficacy of PTEN mRNA in colorectal cancer immunotherapy. By using metal-ion coordination and cell-membrane coating, the system improves mRNA loading, cytosolic delivery, and stability, outperforming traditional lipid nanoparticles. The study also identifies a patient subgroup likely to benefit from PTEN-based treatment, provides an effective mRNA delivery system and conceptual proof for precise cancer immunotherapy.

How hyperspectral imaging technology identifies early-stage weeds in rice fields?
Higher Education PressA review by Professor Abdul Shukor JURAIMI’s team from Universiti Putra Malaysia points out that hyperspectral imaging technology boasts advantages of non-contact operation, high precision, and early detection. Compared with traditional manual visual inspection, it can complete detection within 10–30 days after rice sowing—a critical period when weeds are most competitive—with an identification accuracy generally exceeding 90%. For example, regarding Echinochloa crus-galli and weedy rice (Oryza sativa f. spontanea), the most common weeds in rice fields, researchers achieved identification accuracies of 100% and 92%, respectively, by analyzing spectral data with intelligent algorithms. This accurate identification lays the foundation for targeted weeding: combined with UAVs and prescription mapping technology, it enables site-specific herbicide application, reducing pesticide usage by up to 50%. This not only cuts costs but also alleviates environmental burdens. The relevant article has been published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025619).

Unlocking high-performance perovskite solar cells with 56π-electron fullerene derivatives
Science China PressPeer-Reviewed Publication
Two novel 56π-electron fullerene derivatives, bearing bulky functional groups and named C60-TFB and C60-TFP, were developed and employed as electron transport layers in inverted perovskite solar cells (IPSCs). These new fullerene derivatives demonstrate excellent resistance to dimerization and effective defect passivation, which helps prevent the interdiffusion of iodide ions from the perovskite layer and silver atoms from the cathode. Consequently, the optimized IPSC achieved a high efficiency of 25.93% along with significantly enhanced stability.

Beyond rent: Shared houses in Tokyo offer lifestyle, safety, and community
Shibaura Institute of TechnologyPeer-Reviewed Publication
Shared houses are redefining urban living in Tokyo. By analyzing 1,374 supplier-written property listings through text-mining, researchers identified 11 key promotional themes highlighting safety, community, and convenience as the main selling points. The study uncovers how shared houses are promoted not as low-cost options but as lifestyle-oriented spaces that foster social connection and urban comfort, reflecting Japan’s shifting housing values and evolving notions of city living.
