MiR‐21‐5p Protects Embryonic Growth and Heart Function During Developmental Hypoxia by Dampening HIF Responses and Altering Gene Expression

Comprehensive Physiology, Volume 16, Issue 3, June 2026.
miR‐21‐5p protects embryonic growth and heart function during developmental hypoxia by dampening HIF responses and shifting gene networks toward improved cardiomyocyte survival and calcium handling. This work identifies miR‐21‐5p as a promising therapeutic target for preventing fetal growth restriction and cardiovascular impairment in high‐risk ...

Assessment of Space Weather Impacts on New Zealand Power Transformers Using Dissolved Gas Analysis

Space Weather
Space weather can have major impacts on electrical infrastructure. Multiple instances of transformer damage have been attributed to geomagnetic storms in recent decades, for example, the Hydro Quebec incident of 1989 and the November 2001 storm in New ...

Calcium and Multi‐Isotope Constraints on Cation Exchange in Groundwater

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Cation exchange is one of the most important processes in water‐rock interaction in the presence of clay minerals, with a common Ca‐Mg‐Na exchange system. However, systematic verification of Ca isotopes for tracing cation exchange in natural environments is lacking due to overlapping factors, such as dissolution‐precipitation of Ca‐minerals ...

Maternal cardiometabolic dysfunction and fetal sex‐specific alterations to uterine vascular reactivity in an ovine model of obesity during pregnancy

The Journal of Physiology, Volume 604, Issue 12, Page 5011-5030, 15 June 2026.
Abstract figure legend We developed a novel ovine model of diet‐induced maternal obesity, where ewes were fed a control or obesogenic diet for 60 days pre‐pregnancy and throughout gestation. Pregnant ewes were surgically instrumented to assess maternal cardiovascular function near term.

Exploring Oxygen Electrocatalysis in Phosphonium Ionic Liquids Towards Sodium–Oxygen Batteries

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Sodium–oxygen (Na–O2) batteries are attractive candidates for high‐energy storage systems; however, their long‐term operation is hindered by the instability of highly reactive intermediates such as the superoxide anion (O2•−). Ionic liquids (ILs) have emerged as promising electrolytes not only because of their intrinsic safety but also due to their ...

Stabilized Cellulase in Chitosan–Polyvinyl Alcohol Biopolymer Beads for Sustainable Enzymatic Deinking of Recycled Paper

ChemistryOpen, Volume 15, Issue 4, April 2026.
A stable and reusable biocatalyst, cellulase@Cs/PVA/Ga, is engineered by immobilizing cellulase onto glutaraldehyde‐activated chitosan (Cs) and coating it with polyvinyl alcohol. This composite system enhances enzymatic stability and efficiency for the sustainable deinking of recycled newspaper, offering a green alternative to harsh chemical treatments.

Pyrolysis‐Engineered Fe/Mn‐ZIF Catalysts: Balancing Activity, Selectivity, and Stability for the Oxygen Reduction Reaction

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Metal oxide‐based catalysts for oxygen reduction reaction (ORR) have drawn great attention in recent years. However, it remains technically challenging for the precise regulation of the overall performance due to the trade‐off effect among the activity, selectivity, and stability of electrocatalysts. Herein, a balancing strategy to control the

Tracking via Coccolith Assemblages the East Asian Monsoon and Carbonate Production in the South China Sea During Termination II and Marine Isotope Stage 5e

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Coccolith assemblages from the last 158 kyr, encompassing Marine Isotope Stage (MIS) 5e (130–116 kyr) and preceding deglaciation (Termination II; T‐II), offer important insights about current and future climate changes. The South China Sea (SCS) represents a perfect area for reconstructing past East Asian Monsoon (EAM) dynamics thanks to its ...
