Maternal Obesity Programs Adipogenic Commitment in Neonatal Mesenchymal Stem Cells: A Link to Redox‐Dependent FOXO1 Signaling

Journal of Cellular Physiology, Volume 241, Issue 4, April 2026.
ABSTRACT Maternal obesity increases the risk of obesity and metabolic disease in the offspring, yet the cellular mechanisms that program adipose tissue development remain poorly understood. Mesenchymal stem cells (MSCs), the precursors of adipocytes, may represent an early target of metabolic programming during fetal development.

Fine Characterization of the Contact Zones of Mazzaella laminarioides in the Southeastern Pacific Using Mitochondrial and Nuclear Markers

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates the genetic structure of Mazzaella laminarioides, an ecologically and economically important species from the rocky coast of Chile. Using more accurate sampling and a set of microsatellite, nuclear, and mitochondrial markers, we were able to identify with high resolution the contact zones between the previously described ...

Inland Saline Lakes as Hotspots of Specialized, Nonmarine Protist Diversity: The Case of Arcellinida (Amoebozoa)

Environmental DNA, Volume 7, Issue 4, July–August 2025.
Using a species‐level metabarcoding protocol specific for Arcellinida testate amoebae, we explored the diversity of this mainly freshwater group of protists in saline lakes. We found a large amount of novel diversity, multiple independent transitions across the salinity barrier, and some clades formed and found in athalassohaline lakes, indicating ...

Written in bones: palaeoclimate histotaphonomic history inferred from a complete Megatherium skeleton preserved in the Atacama Desert

Palaeontology, Volume 68, Issue 4, July/August 2025.
Abstract A nearly complete and relatively well‐preserved skeleton of the giant ground sloth Megatherium sp. in the hyperarid core of the Atacama Desert reveals how climate related taphonomic processes drastically transformed these remains over time.

Genomic Signals of Local Adaptation Associated With Environmental Variables in Eleginops maclovinus From Northern Chilean Patagonia

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Studying evolutionary processes in the unique and understudied Patagonian fjord ecosystem is a challenging task for evolutionary ecologists. Genomic signals of local adaptation are present in a species from northern Chilean Patagonia. Polygenic selection drives local adaptation in Eleginops maclovinus. ABSTRACT Understanding the evolutionary mechanisms

Evolutionary Pro‐To‐Thr Mutation in the Intrinsically Disordered Domain of ANP32 Family Members Modulates Their Target Binding Modes

Advanced Science, Volume 12, Issue 12, March 27, 2025.
Protein evolution usually lies on mutations at disordered domains to promote novel functions and regulations. Here it is demonstrated that this is the case of ANP32A and ANP32B, two paralogs with apparently similar structures and functions, where a single amino‐acid substitution in the disordered domain triggers the extended‐to‐compact conformational ...

Diet of Andean Leaf‐Eared Mice (Phyllotis) Living at Extreme Elevations on Atacama Volcanoes: Insights From Metagenomics, DNA Metabarcoding, and Stable Isotopes

Ecology and Evolution, Volume 14, Issue 11, November 2024.
On the flanks of > 6000 m Andean volcanoes that tower over the Atacama Desert, leaf‐eared mice (Phyllotis vaccarum) live at extreme elevations that surpass known vegetation limits. We used a combination of metagenomics, DNA metabarcoding, and stable isotope analyses to investigate the diet of mice living in these extreme environments.
