Clock Genes Regulate Ca2+ Signaling and Mitochondrial Bioenergetics to Inhibit Sjögren Disease

Arthritis &Rheumatology, EarlyView.
Objective Although Ca2+ signaling and metabolism have been identified as key determinants for the development of Sjögren disease (SjD), the intricate connection between them and salivary gland physiology remains poorly understood. Methods Fluorescence‐based Ca2+ imaging, RNA sequencing, and mitochondrial activity were used to investigate the effects of

Footholds for pioneers: How geomorphic features accelerate early marsh assembly

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Ecosystem transitions from bare to vegetated states often stall at early stages, before the biogeomorphic feedbacks needed for further expansion take hold. In aquatic systems, this bottleneck is especially common where inundation and hydrodynamic conditions may impose strong abiotic filters on pioneer establishment.
