A Novel Polyphosphate‐Degrading Enzyme Confers Growth on Exogenous Polyphosphate in the Archaeon Haloferax volcanii

Environmental Microbiology, Volume 28, Issue 7, July 2026.
A novel polyP‐degrading enzyme with an activity differing from those currently known was found in Haloferax volcanii, conferring the ability for this microbe to grow on extracellular polyP. These findings further our understanding of the potential ecological roles of polyP and how archaea metabolise this essential biopolymer.

A Roadmap for Using Hybridisation Capture–Based Target Enrichment of Ancient Environmental DNA in Palaeoecology

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Recovering ancient DNA from environmental samples is transforming the way we understand historical ecosystems. While high‐throughput sequencing of the total DNA in environmental samples (shotgun metagenomic sequencing) reveals the taxonomic contents of these samples, the genetic signals of some taxa (e.g., eukaryotes) can be weak compared to ...

pr2‐Wormifier: A Bioinformatics Pipeline to Create Custom Reference Databases for Improved Metabarcoding of Marine Protists

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT Metabarcoding of environmental and ancient environmental DNA (eDNA and sedaDNA) is a powerful approach for studying and monitoring marine communities. However, its effectiveness is limited by the availability of comprehensive and well‐curated reference databases, particularly for protists.

A New Framework to Empower Ecosystem Assessment Through the Integration of eDNA Inventories, Graph Theory and Niche Modelling

Ecology Letters, Volume 29, Issue 7, July 2026.
There is a lack of conceptual frameworks to validate the integration of eDNA and ecological network analysis into ecosystem monitoring. We propose a tool that combines eDNA inventories, graphlet‐based network analysis, ecological niche modelling and machine learning, and demonstrate that the associated topological metrics are effective for ecological ...

Connecting Bond Switching to Fracture Toughness of Calcium Aluminosilicate Glasses

Journal of the American Ceramic Society, Volume 109, Issue 7, July 2026.
ABSTRACT Fracture toughness is a critical mechanical property of glasses, but a detailed understanding of its link to composition and structure is still missing. Here, focusing on the industrially important family of calcium aluminosilicate glasses, we measure the fracture toughness of two glass series using the single‐edge precracked beam method, one ...

Morphomolecular Characterization of Two New Species of the Genus Bothrostoma Stokes, 1887 (Ciliophora: Metopidae)

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Although species diversity has been extensively studied in anaerobic ciliates, their full diversity is incompletely understood. More research is required to gain further insights into their diversity. In this study, two new metopid ciliates, namely, Bothrostoma oryzaforme nov. sp. and Bothrostoma turgidoryzaforme nov.

Unravelling Past Population Events in Diatoms With Genomic Based Demographic Inferences

Marine Ecology, Volume 47, Issue 4, July/August 2026.
ABSTRACT The biological productivity in the Southern Ocean is mainly driven by the abundance of phytoplankton, which changes with seasons, fluctuations in sea ice and iron as well as light availability. The distribution of biological productivity is further modulated by ocean currents.

The unicellular green microalga Botryosphaerella sudetica links plant‐like light protection with an algal lifestyle

New Phytologist, Volume 251, Issue 1, Page 372-383, July 2026.
Summary Nonphotochemical quenching (NPQ) mechanisms fine‐tune light utilisation in the photosynthetic antenna, for example, in response to excess light, to prevent photodamage. NPQ comprises distinct mechanisms, all contributing to photoprotection but acting on different time scales.
