New Cretaceous Paleomagnetic and Geochronologic Data From the Antarctic Peninsula: Constraints on the Pre‐Opening Tectonic Evolution of the Drake Passage

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.

Influence of Divided Ponds on Fish Diets in Polyculture: Insights From Carbon and Nitrogen Stable Isotopes in Trophic Webs

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
Estimated contributions of food resources to the diets of fish and isotope values of carbon (δ13C) and nitrogen (δ15N) of individual fish using Bayesian stable‐isotope mixing models by species, treatment (open or divided pond) and period (July or October).

Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Further Insights Into the Metabolism of LGD‐4033 in Human Urine. Part 1. Structure Elucidation of Additional Important Metabolites

open access: yesDrug Testing and Analysis, Volume 18, Issue 2, Page 245-259, February 2026.
Well‐characterized, chemically synthesized molecules related to LGD‐4033 metabolism were used as analytical standards for the analysis of LGD‐4033 post‐administration urine samples. This approach offered further insights into LGD‐4033 metabolism, providing solid experimental proof for the structure of important previously reported metabolites and ...

Fat‐Corrected Non‐Gaussian Diffusion MRI for Liver Fibrosis Assessment in Metabolic Dysfunction‐Associated Steatotic Liver Disease

open access: yesJournal of Magnetic Resonance Imaging, Volume 63, Issue 2, Page 497-507, February 2026.
ABSTRACT Background In patients with metabolic dysfunction‐associated steatotic liver disease (MASLD), non‐Gaussian diffusion—weighted imaging (DWI) has been proposed for the diagnosis of liver fibrosis, but its measurement is partially confounded by steatosis.

Cleavage and Polyadenylation Specificity Factor Subunit 5 Regulates Pulmonary Artery Smooth Muscle Expansion and Hypoxic Response

open access: yesMedComm, Volume 7, Issue 2, February 2026.
Increased miR‐3163 targets NUDT21, reducing CPSF5 levels and driving APA dysregulation. This results in 3′UTR shortening of CBFB, which stabilizes RUNX1 and promotes smooth muscle proliferation. PTGER3, is also shortened amplifying hypoxia‐induced RVSP. Together, these pathways contribute to vascular remodeling in PH. Image Created in https://BioRender.

Strength α‐Quartz: New Results From High Pressure In Situ X‐Ray Diffraction Experiments

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present a suite of 13 uniaxial deformation experiments on fine grained polycrystalline α‐quartz conducted in a D‐DIA apparatus monitored with in situ synchrotron x‐rays. Experimental temperatures range from 25°C to 1199°C with pressures between 1.4 and 3.2 GPa, and strain rates between 3.4 × 10−6 s−1 and 1.8 × 10−5 s−1.
