A summer in the Greater Paris: trophic status of peri-urban lakes shapes prokaryotic community structure and functional potential

This study examines how trophic status affects prokaryotic community structure and functional potential in nine peri-urban lakes around Paris over a summer season.

Limnospira (Cyanobacteria) chemical fingerprint reveals local molecular adaptation

The paper identifies distinct chemical fingerprints in Limnospira strains linked to their biogeographic origins and environmental adaptations.

Multi-omics analyses from a single sample: Prior metabolite extraction does not alter the 16S rRNA-based characterization of prokaryotic community in a diversity of sample types

The paper compares 16S rRNA-based prokaryotic community characterization after direct DNA extraction versus metabolite extraction followed by DNA extraction across diverse samples, finding no impact on community composition.

Lifelong tissue memory relies on spatially organised dedicated progenitors located distally from the injury

The paper shows that wound repair leads to the formation of spatially organized memory progenitors that enhance future wound healing but also increase tumorigenesis risk.

Gut microbiota and holobiont metabolome composition of the Medaka fish (Oryzias latipes) are affected by a short exposure to the cyanobacterium Microcystis aeruginosa

This study shows that a 2-day exposure to Microcystis aeruginosa in medaka fish alters gut microbiota and metabolome composition, with microbiota changes occurring faster than metabolome changes.

Disruption of fish gut microbiota composition and holobiont metabolome by cyanobacterial blooms

This study shows that cyanobacterial blooms alter fish gut microbiota composition and holobiont metabolome, with potential ecological and aquaculture implications.

Fibrinogen αC-subregions critically contribute blood clot fibre growth, mechanical stability and resistance to fibrinolysis

This study investigates the role of fibrinogen αC-subregions in clot structure, mechanical stability, and resistance to lysis using recombinant variants.

Characterization of cyanobacteria isolated from thermal muds of Balaruc-Les-Bains (France) and description of a new genus and species Pseudochroococcuscouteii

The paper isolates and characterizes cyanobacteria from thermal muds, describing a new genus and species and hypothesizing their potential role in the therapeutic properties of the mud.

Toxicity, transfer and depuration of anatoxin-a (cyanobacterial neurotoxin) in medaka fish exposed by single-dose gavage

This study examines the toxicity, transfer, and depuration of anatoxin-a in medaka fish after single-dose gavage, finding no mortality at sub-acute doses and rapid toxin clearance.

Global metabolomic characterizations of Microcystis spp. highlights clonal diversity in natural bloom-forming populations and expands metabolite structural diversity

The paper characterizes metabolomic diversity in Microcystis strains to reveal clonal variation and expanded metabolite structural diversity.

Subcellular localization of microcystin in the liver and the gonad of medaka fish acutely exposed to microcystin-LR

This study investigates the subcellular localization of microcystin-LR in the liver and gonads of medaka fish after acute exposure, revealing its presence in reproductive cells for the first time in a vertebrate model.

Specific metabolic signatures of fish exposed to cyanobacterial blooms

The paper analyzes liver metabolomes of two fish species exposed to cyanobacterial blooms and finds similar metabolic changes across species.
