White Is a New Shade of Blue Carbon: A Case Study of a Traditional Salt Production Pond That is a Net Carbon Sink

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract To address for the first time the carbon budget of traditional salterns, we measured the diel, seasonal, and spatial variability of water‐air CO2‐eq fluxes (CH4 and CO2) and the Organic Carbon (OC) stock and burial rate in the sediment. Temperature, salinity, dissolved oxygen, pH and wind were assessed as potential environmental drivers of the

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

Journal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Tabernaemontana catharinensis: A Source of Indole Alkaloids With Potential Activity as Chemotherapeutic Agents

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT This study aimed to evaluate the antitumor activity of fractions rich in indole alkaloids extracted from the leaves of the species Tabernaemontana catharinensis. The chemical composition was analyzed using high‐resolution mass spectrometry (HRMS), which identified nine known indole alkaloids, including voacangine, voacangine hydroxyindolenine,

Substrate regulation of histone acetyltransferase from Artemia salina

Biochemical and Biophysical Research Communications, 1980
Histone H1 is the best substrate for the histone acetyltransferase from Artemia, while the acetylation of unfractionated histones by the isolated enzyme or the acetylation of endogenous histones in nuclear suspensions is exclusively confined to the arginine rich histones, H3 and H4.

Unspecific Peroxygenases‐Catalyzed Oxidation of Pharmaceutical Compounds Considered Emerging Contaminants

ChemBioChem, Volume 27, Issue 8, April 2026.
PaDa‐I and JaWa, two evolved UPO variants, catalyze the oxidation of 9 out of 12 pharmaceutical emerging contaminants, with TTN up to 4500. The enzymes exhibit distinct substrate selectivity. Only PaDa‐I can catalyze the simultaneous oxidation of substrates in wastewater samples.

A Standardized Unpredictable Chronic Stress Protocol for Adult Zebrafish

Current Protocols, Volume 6, Issue 4, April 2026.
Abstract The unpredictable chronic stress (UCS) protocol, originating in the 1980s, has contributed to depression research by inducing behavioral and physiological changes in rodents that resemble the symptoms observed in patients. Its translational potential led to widespread adoption, but adaptations and variations to the protocol have raised ...
