Environmental regulation and disruption of shell biomineralization in bivalves and gastropods: a mechanistic review
Molluscan shells face escalating threats from climate change, altered seawater chemistry, contaminants, and biotic factors, disrupting the intricate process of biomineralization. This review synthesizes a conditional hierarchical response framework, detailing how ionoregulatory and acid-base disturbances manifest at molecular, microstructural, and macroscopic levels, impacting shell strength and growth. Integrated multi-omics research is crucial to identify thresholds and predict adaptive potential, informing conservation strategies.

A cross-polarized light scattering sensor for measuring the concentration of particulate inorganic carbon in seawater: laboratory validation
Understanding the marine carbon cycle necessitates comprehensive observations of particulate inorganic carbon (PIC) concentrations. World Data Ocean introduces two autonomous optical sensor prototypes leveraging cross-polarized light scattering to measure PIC in seawater, offering a cost-effective alternative to traditional methods. Laboratory validation demonstrated sensitivity across a broad oceanic range (0.1-400 μg C L−1), revealing species-specific optical signatures. These findings establish a framework for future in situ measurements; for broader context on ocean color observations, see "NASA captured the Black Sea turning brilliant turquoise from space."
