Cancer cell-derived small extracellular vesicles (sEVs) can travel from distant tumors through the bloodstream and kidneys and be excreted into urine, as reported by researchers at Science Tokyo. Using sophisticated molecular tagging systems in mouse models of brain, lung and pancreatic cancer, the researchers directly traced sEVs from tumors to urine. They also revealed that the kidney’s glomerular cells actively transport sEVs across the filtration barrier, supporting their use in emerging urine-based cancer diagnostics.

Researchers from the Institute of Physics and the Institute of Molecular and Cell Biology of the University of Tartu have shown in a recently published study that antibacterial coatings which initially appear highly effective at destroying bacteria, may lose their performance over time. Therefore, long-term testing is essential for developing the best antibacterial materials. The article describing the results of the study, “Artificial aging induced changes in ZnO- and TiO₂-based polyacrylic surface coatings,” was published in the journal npj Materials Degradation.

Hepatitis C virus (HCV) infects an estimated 50 million people worldwide, according to the World Health Organization, and remains a leading cause of cirrhosis and liver cancer. While antiviral drugs can cure most infections, global access remains limited and these drugs do not stop reinfection.

Understanding how cells are organized and how their molecular components interact in a coordinated and cooperative manner is a central goal of modern life sciences. To answer these questions, researchers need to observe many structures inside the same cell at once and map how they are arranged and interact. This requires “multiplexed super-resolution microscopy”—an advanced imaging approach that reveals cellular details far beyond the limits of conventional light microscopes.
