Self‐Limiting of Artificial Electron Radiation Belts: Evidence From the Starfish Prime High‐Altitude Nuclear Explosion

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The 1962 Starfish Prime high‐altitude 1.4‐megaton nuclear detonation injected large amounts of fission‐produced energetic electrons into the inner magnetosphere (L = 1.12), creating an intense artificial radiation belt that persisted for years. In this study, we revisit historical data from this unprecedented event to investigate the potential

Overall Prediction of Breakthrough Curves in Fracture Networks Using Graph‐Based Simulation and Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Discrete fracture network (DFN) models are widely used to simulate fluid and solute transport through fracture networks that serve as their preferential pathways. In DFN models, fractures are generated stochastically based on fracture properties.

Gregorio y Francisco Esparza: hermanos enfrentados ante la independencia de Texas, 1835-1836 Gregorio and Francisco Esparza: Brothers Who Fought Each Other During the Independence of Texas, 1835-1836

Secuencia, 2012
En 1836 el ejército mexicano tomó el fuerte de El Álamo, en las afueras de San Antonio. Todos sus defensores, que combatían por la independencia de Texas, murieron en la acción, entre ellos Gregorio Esparza, un nativo de esa ciudad.

Merged Interplanetary Data From L1: MIDL

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The availability and accuracy of upstream solar wind conditions are critical for solar wind—magnetosphere coupling studies, whether based on observations or numerical models and simulations. We present the Merged Interplanetary Data from L1 (MIDL), which merges 1‐min magnetic field and plasma observations from ACE, DSCOVR, and Wind through a ...

Relationships and differences between the Triassic ammonoid successions of northwestem Sonora, Mexico, and west-central Nevada, U.S.A.

Revista Mexicana de Ciencias Geológicas, 2019
The Antimonio Formation exposed in the Sierra del Álamo, northwestern Sonora, consists of an Upper Permian-Lower Jurassic marine succession of sedimentary rocks that disconformably overlies  the Guadalupian-age Monos Formation… in order to continue ...

Uncovering hidden bias in neutron diffraction residual strain measurements

Journal of Applied Crystallography, Volume 59, Issue 4, Page 991-1004, August 2026.
This work demonstrates that diffraction‐based residual strain calculations and uncertainty estimates depend on how grain populations are sub‐sampled, with important implications for interpreting residual stresses in heterogeneous materials with fine‐scale microstructure and strain gradients.When calculating residual strain via neutron or X‐ray ...

PETIMOT: a novel framework for inferring protein motions from sparse data using SE(3)‐equivariant graph neural networks

Acta Crystallographica Section D, Volume 82, Issue 8, Page 862-885, August 2026.
We present a new formulation for protein flexibility and learn protein motions from sparse experimental data.Proteins move and deform to ensure their biological functions. Despite significant progress in protein structure prediction, approximating conformational ensembles under physiological conditions remains a fundamental open problem.

Plasticity in parental care: Interspecific competitor cues shape biparental cooperation in a burying beetle

Journal of Animal Ecology, Volume 95, Issue 8, Page 1358-1371, August 2026.
Our study contributes to our understanding of the effects of interspecific competition in species with biparental care where male and female parents must somehow coordinate their response to interspecific competition. Abstract Interspecific competition is an important evolutionary driver of many species' life histories and behaviours, arising wherever ...

Long‐Term Biodiversity–Stability Relationship in Temperate Mountain Forests

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Theories on ecological stability lack the long‐term observational data necessary to comprehend the dynamics of durable and complex ecosystems like forests; consequently, the influence of biodiversity on ecosystem stability remains predominantly unexplained.

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...
