Ocean acidification at the crossroads I: Harmonizing unpurified and purified meta‐cresol purple spectrophotometric pHT measurements based on absorbance data

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 4, April 2026.
Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

Assessing the ability of white-rot fungi to tolerate polychlorinated biphenyls using predictive mycology

open access: yesMycology, 2018
The aim of the present study was to assess the ability of different white-rot fungi to tolerate polychlorinated biphenyls (PCBs) using predictive mycology, by relating fungal growth inhibition to ligninolityc enzyme secretion.

Multivalent Protein Nanorings for Broad and Potent SARS‐CoV‐2 Neutralization

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 10, 13 March 2026.
A protein‐only, modular multivalent nanoscaffold displaying 20 anchor points, decorated with two different binders (10 of each), targeting the SARS‐CoV‐2 receptor‐binding domain is presented. The construct self‐assembles into stable, biocompatible, homogeneous nanoparticles, exhibit synergistic binding with fM IC50 values. It also detects spike at 9 ng

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles

open access: yesJournal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

On the Role of Western Boundary Currents to Fertilize Adjacent Continental Shelves at Interannual Scales: A Case Study in the Southwestern Atlantic

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Exchanges between continental shelves and open ocean basins regulate the transport of heat, salt, and nutrients. In the Southwestern Atlantic, the western boundary current known as the Malvinas Current (MC) fertilizes the outer shelf through recurrent slope‐water intrusions.

ONDAS DE PÉRDIDA MAGNETOHIDRODINÁMICAS EN UN PLASMA DE TRES CAPAS: MECANISMOS DE PÉRDIDA

open access: yesAnales (Asociación Física Argentina), 2013
La aplicación del Análisis de Fourier para obtener las ondas de pérdida tiene la ventaja de la simplicidad, pero no queda claro porque la raíces complejas de las relaciones de dispersión representan ondas de pérdida, ni cómo se produce dicha pérdida.

Fetal sex shapes maternal immune adaptation: placental extracellular vesicles differentially reprogram the phenotype, metabolism, and function of circulating monocytes

open access: yesFrontiers in Immunology
IntroductionMaternal immune adaptation during pregnancy is orchestrated by dynamic signals from the uterine microenvironment, including placental extracellular vesicles (pEVs) released into maternal circulation.
