- PMID 42073165 (2026, Foods (Basel, Switzerland)) — Advances in Nanotechnological Strategies for Preserving and Authenticating Bioactive Compounds in Extra Virgin Olive Oil: Nano-Enabled Stabilization, Sensing, and Circular Valorization.. Abstract (opening): Extra-virgin olive oil (EVOO) is a chemically complex lipid matrix whose minor constituents-especially phenolic secoiridoids-drive sensory quality, oxidative stability, and health benefits. However, these bioactives are vulnerable to heat, light, oxygen, and pro-oxidant metals during processing and distribution, while the high cost of EVOO often makes it a target for adulteration and mislabeling. This review critically assesses nano-enabled, food-grade strategies that (i) preserve phenolics and aroma compounds through nanoencapsulation, inclusion complexes, Pickering stabilization, and structured lipid systems; (ii) control their release and bioaccessibility during digestion; and (iii) enhance authenticity verification via sensor-ready packaging, spectroscopy/chemometrics, and digital traceability systems (IoT, machine learning, blockchain). We align these innovations with the "product identity constraints" of the EVOO category and with official quality standards used in routine control (IOC/EU). Finally, we explore circular valorization of olive-mill by-products within food-centered biorefineries, outlining pathways to convert biomass into ingredients, materials, and energy, thus reducing environmental impacts. Research priorities are proposed to develop scalable, regulation-compliant nanotechnologies that extend shelf life and increase consumer trust without compromising EVOO category standards. *[CC BY — Open Access, verbatim with attribution.]*

- PMID 40941278 (2025, Animals : an open access journal from MDPI) — Effects of Enclosure Size on the Preferences of Juvenile Chinchillas (<i>Chinchilla lanigera</i>).. Abstract (opening): This study investigated the cage size preferences of juvenile chinchillas using enclosures that allowed free choice between different dimensions. Three comparisons were tested: (1) small floor area (0.15 m<sup>2</sup>) vs. double floor area (0.30 m<sup>2</sup>) at constant height; (2) low height (0.4 m) vs. high height (1.0 m) at constant floor area (0.15 m<sup>2</sup>); and (3) small-low cage (0.15 m<sup>2</sup> × 0.4 m) vs. large-high cage (0.30 m<sup>2</sup> × 1.0 m). The juveniles consistently preferred the smaller or lower enclosures across all trials. In the floor area tests, chinchillas spent about 66-75% of their time in the small cage compartments (<i>p</i> < 0.001). In the height comparison, the low cage was preferred by 70% (<i>p</i> < 0.001). When both floor area and height were increased, the small-low cage was preferred by 79% (<i>p</i> < 0.001). Differences in preference were most evident during the daytime period. At night, however, cage utilization was more even. These results indicate that young chinchillas strongly prefer smaller, lower spaces. Based on these preference tests alone, simply providing larger cages (without other modifications) did not result in greater use by juvenile chinchillas. These unexpected results suggest that factors such as safety or familiarity drive juveniles to choose smaller enclosures. Further research is needed to clarify the motivation behind these preferences and to determine how best to incorporate them into improved welfare-oriented housing designs. *[CC BY — Open Access, verbatim with attribution.]*
