Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus

New Phytologist, EarlyView.
Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...

Metacaspases contribute to the cellular response to heat stress in a marine diatom

New Phytologist, EarlyView.
Summary Climate‐driven marine heatwaves (HW) are extreme, large‐scale events characterized by elevated ocean temperatures lasting from days to months. Despite their importance, little is known about the molecular mechanisms of algal response to marine HW. Recent studies suggest that metacaspases play an important role in thermotolerance.

Loss of qE Does Not Necessarily Lead to Photoinhibition: Sustained Non‐Photochemical Quenching in the Absence of PsbS and Zeaxanthin

Plant, Cell &Environment, EarlyView.
ABSTRACT Photosynthetic light‐harvesting complexes mediate light absorption and energy dissipation. By modulating the photosystems' absorption cross‐section, they affect both photosynthetic activity and non‐photochemical quenching (NPQ). These processes are often studied by spectrally integrated chlorophyll fluorescence, masking their associated ...

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Trophic Changes off Southwest Greenland During the Holocene and Their Influence on Carbon Burial

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Organic carbon (OC) burial in sediments is partly controlled by catabolic biodegradation and remineralization by heterotrophic bacteria, but long‐term records of these bacterially‐mediated processes have not been available. Here, we use stable hydrogen isotope ratio of the saturated C16 fatty acid (δ2HC16:0) as a proxy of the prevalence of ...

Compressible Flow Exfoliation of Two‐Dimensional Nanomaterials: Insights Into Layer Separation Informed by Gas Dynamics

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
This study elucidates the mechanism of compressible flow exfoliation for producing 2D hexagonal boron nitride (h‐BN). Fluid dynamics analysis reveals that acceleration‐driven aerodynamic shear forces, rather than shock waves alone, drive effective layer separation.

First Principles Rovibronic Absorption Spectra of HF Molecule

Journal of Computational Chemistry, Volume 47, Issue 6, March 5, 2026.
Hydrogen fluoride (HF) is astrophysically important, as it has been detected in sunspots, Venus, red giants, and the interstellar medium, serving as a probe of exoplanet atmospheres. This article presents an ab initio investigation of HF rovibronic spectroscopy, combining high‐level electronic‐structure data with nuclear‐motion solutions and refinement
