Microbial mats and thalassinid shrimp: Spatial and geochemical interactions in a modern intertidal environment

open access: yesSedimentology, EarlyView.
ABSTRACT This research examines the spatial and geochemical interactions between mat‐forming microorganisms and thalassinid shrimp in an intertidal flat situated on the shores of Willapa Bay, Washington, USA. The study serves as a contemporary analog for the relationships between mats and burrowing organisms in deep time.

Near‐Synchronous Cambrian Evolution of the Transbrasiliano‐Kandi‐4°50′ Shear Zone in South America and Africa

open access: yesTerra Nova, EarlyView.
ABSTRACT The Transbrasiliano‐Kandi‐4°50′ (TK4) shear zone in western Gondwana crosscuts South America and NW Africa for at least 6000 km. Despite its impressive size, the timing of the main episode of dextral ductile shearing is uncertain. We present detailed in situ multi‐mineral geochronology of mylonites from both Brazil and Algeria supporting that ...

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

Modulatory Effects of Folic Acid and Dental Pulp Stem Cell‐Derived Exosomes on Gene Expression in a Periodontal Injury Model

open access: yesNatural Sciences, Volume 6, Issue 2, April 2026.
Dental pulp stem cellderived exosomes and folic acid are evaluated for their effects on gene expression in an in‐vitro periodontal injury model. Human gingival fibroblasts subjected to oxidative and mechanical injury are treated with folic acid, exosomes, or their combination.

Insect‐Derived Bioactives for Glycemic Control and Gut Health: A Review

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
Insect‐derived bioactive compounds (e.g., peptides, polysaccharides) effectively regulate blood glucose through dual mechanisms: directly inhibiting carbohydrate‐digesting enzymes and glucose transporters, and indirectly modulating gut microbiota to enhance intestinal barrier integrity.
