ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: April 24, 2025

Oxygen sensing is essential across a wide range of fields, from understanding cellular metabolism and disease mechanisms to optimizing industrial environmental processes. In this Perspective, we highlight key developments in optical architectures (at the nanometer sub-micrometer scale), including their transduction methods applications vitro, vivo/in situ, nonbiological systems. We also discuss future directions for field domain expanding extra/intracellular sensing. address improving accessibility nonexpert users through need standardized protocols scalable production methods. Furthermore, advocate fostering interdisciplinary collaborations academic incubators, conference networking, strategic citation practices bridge gaps between fundamental research applied science expand impact these tools researchers outside field. Addressing challenges will help drive development more versatile widely accessible oxygen sensors, thus advancing innovation diverse disciplines.

pH regulation in coral photosymbiosis and calcification: a compartmental perspective

New Phytologist, Journal Year: 2025, Volume and Issue: unknown

Published: May 14, 2025

Summary The coral‐dinoflagellate photosymbiosis and coral calcification underpin shallow water, reef ecosystems. This review examines the pivotal role of pH regulation in cell physiology these processes. Despite simple tissue organization, photosymbiotic corals maintain a complex internal microenvironment, with distinct compartments exhibiting contrasting levels. For example, acidic ‘symbiosome’ surrounds algal symbionts, while alkaline ‘extracellular calcifying medium’ occurs at growing front skeleton. We discuss how is crucial to functioning calcification, as well mitigating acid–base imbalances that processes create. interplay between also discussed, focusing on influence symbiont photosynthesis transepithelial gradients distribution energy sources colony. Throughout this review, insights into derived from previous research ocean acidification are integrated deepen understanding. Finally, we propose priorities advance knowledge resilience under changing conditions, such investigating inorganic carbon concentration within compartments, species‐specific differences impacts thermal stress regulation.

Saving coral reefs: significance and biotechnological approaches for coral conservation

Advanced Biotechnology, Journal Year: 2024, Volume and Issue: 2(4)

Published: Nov. 22, 2024

Coral reefs are highly productive ecosystems that provide valuable services to coastal communities worldwide. However, both local and global anthropogenic stressors, threaten the coral-algal symbiosis enables reef formation. This breakdown of symbiotic relationship, known as bleaching, is often triggered by cumulative cell damage. UV heat stress commonly implicated in but other factors may also play a role. To address coral loss, active restoration already underway many critical regions. Additionally, researchers exploring assisted evolution methods for greater resilience projected climate change. review provides an overview mechanisms underlying bleaching response strategies being pursued loss. Despite necessity ongoing research all aspects this field, action on change remains crucial long-term survival reefs.
