Postmenopausal women are at higher risk for both osteoporosis and depression, yet no single treatment effectively addresses both conditions because their shared biological basis remains poorly understood. In a recent study, researchers discovered that a traditional plant extract used in traditional Chinese medicine could act on a common molecular pathway underlying both bone loss and mood disorders, paving the way for treatments that target both conditions at once.

Antibiotic resistance is making bacterial infections harder to treat, demanding new therapeutic strategies. A new review highlights bacterial extracellular vesicles (BEVs) as promising nanoscale tools that can kill pathogens, block infection, enhance vaccines, and deliver drugs. By integrating genetic, chemical, and physical engineering, researchers demonstrate how BEVs can be transformed into customizable “nanoweapons.” This approach could reshape infection treatment by enabling safer, targeted, and more effective alternatives to conventional antibiotics.
