A study published in PhotoniX Life presents a label-free method for mapping subcellular dynamics using wide-field interferometric scattering (iSCAT) microscopy and power spectral density (PSD) analysis. By fitting the pixel-wise PSD of iSCAT signals to an inverse-power-law relationship over 30–1,250 Hz, the researchers generated spectral exponent maps that visualize the characteristics and strength of subcellular motion. The method distinguished between mitotic and interphase cells, between live and apoptotic cells, and among thyroid cancer cell subtypes with increasing malignancy, highlighting a potential intrinsic optical marker for mechanobiology, cancer research, and stem cell assessment.

A joint research team from China Pharmaceutical University, Chinese Academy of Agricultural Sciences, National Engineering Research Center for the Emergency Drug, and Shandong Agricultural University has developed a novel multisite bridging‑mediated lateral flow immunoassay (mbLFIA) that enables ultrasensitive, enzyme‑free, visual on‑site detection of mosquito‑borne viruses such as chikungunya virus (CHIKV). The breakthrough, published in Targetome, addresses a critical global need for field‑deployable diagnostics in resource‑limited regions, where conventional nucleic acid tests rely on bioenzymes and bulky laboratory instruments.

A novel natural compound crocin II from saffron directly targets ANGPTL8, a key driver of metabolic dysfunction‑associated steatotic liver disease (MASLD), and promotes its degradation via the autophagosome‑lysosome pathway. This PROTAC‑like mechanism suppresses lipogenesis, restores lipid metabolism, reverses hepatic steatosis, insulin resistance, and hyperlipidemia in preclinical models, with excellent organ safety, providing a safe, translatable natural strategy for MASLD therapy.

A new study reveals cathepsin S (CTSS) as a key immune checkpoint driving cholestatic liver injury by skewing invariant natural killer T (iNKT) cells toward pathogenic iNKT17 polarization. The natural product celastrol directly binds and inhibits CTSS, restores autophagy/mitophagy in iNKT cells, reprograms the liver immune microenvironment toward protective iNKT1 polarization, alleviates cholestasis, and halts liver fibrosis, establishing a safe, translatable immune‑targeting strategy for cholestatic liver diseases.

The utilization of light as an external stimulus to promote the generation of hot electrons in plasmonic heterostructures and thus augment their catalytic efficacy presents significant potential for bacterial biofilm eradication. Towards this goal, Scientist in China engineered a Ti/ePt-Au NBPs/RGDC implant, which not only brought the redshift of the NIR absorption peak, but also accelerated charge separation. The proposed strategy holds tremendous promise for developing next-generation smart coatings to combat implant-associated biofilm infections.

A novel metabolic engineering strategy enhances riboflavin production by manipulating intracellular guanine levels through transporter engineering, demonstrating that overexpression of the NupG transporter can increase riboflavin titers by 15.3%.

A comprehensive genetic toolkit was developed for engineering Streptococcus species, addressing a critical need for better regulatory tools in these industrially important lactic acid bacteria. The study introduces short synthetic promoters and efficient sRNA-based repressors that enable streamlined control of gene expression.
