Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.

Effect of Anabaena sp. PCC7120 on the Tolerance of Rice ( Oryza sativa L. cv Maratelli) Seedlings Against Lindane

Land Degradation &Development, Volume 37, Issue 7, Page 2873-2885, 30 April 2026.
ABSTRACT Lindane (γ‐hexachlorocyclohexane, γ‐HCH) is a broad‐spectrum pesticide widely used since the 1950s until its inclusion in the Stockholm Convention list of Persistent Organic Pollutants (POPs) in 2009, together with other HCH isomers. The high persistence and mismanagement of the toxic wastes generated during its synthesis have led to serious ...

A Bifunctional Protease Cleaves the Leader Peptide in the Biosynthesis of Class I Microviridins

ChemBioChem, Volume 27, Issue 7, 14 April 2026.
Biochemical characterization of the peptidase candidate NosP reveals bifunctional endo‐ and aminopeptidase activity in the leader peptide removal of class I microviridins from Nostoc punctiforme. The discovery of the first leader‐processing peptidase from microviridin biosynthesis may pave the way for the efficient production and bioengineering of ...

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Reconstructing post‐crisis recovery in the hinterlands of Constantinople: A high‐resolution first‐millennium CE pollen record from Lake Yeniçağa (NW Türkiye)

Journal of Quaternary Science, Volume 41, Issue 3, Page 520-539, April 2026.
ABSTRACT Facing a novel plague pandemic, military invasions, and political–economic transformations, societies of the eastern Roman (Byzantine) empire had to adapt to a variety of pressures and new ways of exploiting their natural environments during the mid‐1st millennium CE.

Seasonal nitrate drawdown transitions lake ecosystems from phosphorus to nitrogen deficiency in annual cycles

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Phytoplankton biomass is often limited by nitrogen (N) and/or phosphorus (P). Quantifying the relative availability of N and P in an ecosystem is useful in indicating nutrient limitation status. In subtropical lakes, nitrate availability generally follows a seasonal pattern with maxima in the late winter/early spring and minima in late summer ...

Molecular and phylogenetic characterization of two species of the genus Nostoc (Cyanobacteria) based on the cpcB-IGS-cpcA locus of the phycocyanin operon [PDF]

Journal of BioScience and Biotechnology, 2012
Traditionally, the taxonomy of the genus Nostoc is based on morphological and physiological characters. The extreme morphological variability of the Nostoc species, due to their life cycle and environmental conditions, hampers the correct identification ...

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 ...
