Full‐Length 16S and 18S rRNA Long‐Read Sequencing Reveals Gut Microbiome Diversity in the European Brown Hare (Lepus europaeus)

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Full‐length 16S and 18S rRNA Oxford Nanopore sequencing of large intestine contents from 30 healthy European brown hares revealed broad gut microbiome diversity. An 80% identity threshold detected substantially greater taxonomic richness than 95%, emphasizing the value of long‐read sequencing in wildlife microbiome research. ABSTRACT The European brown

Deciphering the properties and reaction mechanism of anhydromevalonate phosphate decarboxylase, a prenylated flavin mononucleotide‐dependent enzyme in the archaeal mevalonate pathway

The FEBS Journal, Volume 293, Issue 11, Page 3303-3319, June 2026.
Characterization of anhydromevalonate phosphate decarboxylase, the UbiD‐family decarboxylase involved in the archaeal mevalonate pathway, was conducted. The enzyme is responsible for the biosynthesis of isoprenoids, such as archaeal membrane lipids, respiratory quinones, and dolichols.

Lipid hydrogen isotope compositions primarily reflect growth water in the model archaeon Sulfolobus acidocaldarius

Applied and Environmental Microbiology
The stable hydrogen isotope composition (δ2H) of lipid biomarkers can track environmental processes and remain stable over geologically relevant time scales, enabling studies of past climate, hydrology, and ecology.

The Elusive Fraction of Marine Plankton Diversity: Size, Abundance and Taxonomic Composition of 0.2 μm‐Filterable Prokaryotes Across Three Contrasting Coastal Environments

Molecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT The existence of prokaryotes escaping filtration through 0.2‐μm filters has been known for decades. Such ‘filterable’ prokaryotes (hereafter ‘FP’) might include true ultra‐small groups (i.e., ultramicrobacteria), but also cells that miniaturize temporally as a physiological strategy to persist under unfavourable conditions, representing a ...

The distribution and abundance of archaeal tetraether lipids in U.S. Great Basin hot springs

Frontiers in Microbiology, 2013
Isoprenoidal glycerol dialkyl glycerol tetraethers (iGDGTs) are core membrane lipids of many archaea that enhance the integrity of cytoplasmic membranes in extreme environments.

Archaeal ether lipids improve internalization and transfection with mRNA lipid nanoparticles

European Journal of Pharmaceutics and Biopharmaceutics
Neutral and positively charged archaeal ether lipids (AEL) have been studied for their utilization as novel delivery systems for pDNA, showing efficient immune response with a strong memory effect while lacking noticeable toxicity. Recent technological advances placed mRNA lipid nanoparticles (LNPs) at the forefront of next-generation delivery systems;

Asymmetric Reduction of Unactivated Alkenes

Chemistry – A European Journal, Volume 32, Issue 18, 14 May 2026.
Unactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...

Structural biology of ferritin nanocages

FEBS Letters, Volume 600, Issue 10, Page 1420-1443, May 2026.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats

Advanced Science, Volume 13, Issue 26, 8 May 2026.
ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...
