The Electronically Confined Space Analogy Elucidates How Second‐Row Triatomic 18‐Valence‐Electron Molecules Shape Life and Light

open access: yesChemistryOpen, Volume 15, Issue 3, March 2026.
The Electronically Confined Space Analogy explains ozone's unique UV absorption by linking bent 18‐valence‐electron structures to enhanced stability and photochemical activity, offering a molecular‐level rationale for its dominance as Earth's stratospheric UV filter.

When honeybees come to town: Critical aspects of urban beekeeping and opportunities for regulation

open access: yesPeople and Nature, Volume 8, Issue 3, Page 528-540, March 2026.
Abstract Urban areas are increasingly valued for their role in conserving wild pollinators. Honeybees are often regarded as ambassador species for pollinator conservation, and beekeeping is frequently perceived as a pro‐biodiversity activity, which has become highly popular in urban areas.

Imatge i coneixement antropològic

open access: yesAnàlisi: quaderns de comunicació i cultura, 2021
This article offers an exploration into the relationship between the image and knowledge in social anthropology from two points of view. First, how anthropological knowledge has approached the study of the image, and second, how the image has been used in the history of anthropology, especially in ethnographic field work.

Glycative Stress Disrupts the Mitochondrial‐Lysosome Axis and Promotes Geroconversion in Aging Cardiomyocytes

open access: yesAging Cell, Volume 25, Issue 3, March 2026.
Cardiac aging promotes mitochondrial AGE accumulation driven by defective glycative stress detoxification. AGE‐modified mitochondria disrupt lysosomal proteolysis, impairing mitophagy and promoting lipofuscin buildup. This mechanism sustains chronic unresolved mitochondrial damage, driving proinflammatory senescence in cardiomyocytes and defining a ...

Experienced climate change impacts help explain subjective well‐being—Evidence from 14 nature‐dependent communities

open access: yesPeople and Nature, Volume 8, Issue 2, Page 461-475, February 2026.
Abstract Climate change profoundly affects well‐being in complex and interconnected ways. However, the relationship between climate change and well‐being has been explored in only a handful of settings, most of which are industrialized. Here, we investigate the association between perceived climate change impacts, their severity and subjective well ...

Impact of climate change mitigation strategies in rice farming on agroecosystem multifunctionality

open access: yesJournal of Applied Ecology, Volume 63, Issue 2, February 2026.
These results suggest that, from a landscape management perspective, implementing a single irrigation strategy at large spatial scales should be discouraged due to potential negative effects on particular sets of ES components. Conversely, a mosaic of irrigation strategies should be implemented, promoting ES components aligned with site‐specific ...

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

open access: yesAdvanced Functional Materials, Volume 36, Issue 2, 5 January 2026.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Exploring the Role of TAS2Rs in Obesity: Insights From Human and Rat Models

open access: yesObesity, Volume 34, Issue 1, Page 162-174, January 2026.
ABSTRACT Objective Obesity is a chronic disease with various causes and diverse treatments, including dietary restriction and bariatric surgery. Bitter taste receptors (TAS2Rs), found in the oral cavity and gastrointestinal tract (GIT), are implicated in digestive and metabolic regulation, but their role in obesity remains unclear.

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

open access: yesAdvanced Materials, Volume 37, Issue 49, December 10, 2025.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...
