Segmentation and Tracking of Eruptive Solar Phenomena With Convolutional Neural Networks

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Solar eruptive events are complex phenomena, which most often include coronal mass ejections (CME), CME‐driven compressive and shock waves, flares, and filament eruptions. CMEs are large eruptions of magnetized plasma from the Sun's outer atmosphere or corona, that propagate outward into the interplanetary space.

Reconstructing Environmental and Microbial Ecosystem Changes Across the Permian–Triassic Mass Extinction at Lusitaniadalen, Svalbard

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract The Permian–Triassic environmental crisis triggered fundamental changes in marine ecosystems, culminating in the most severe biodiversity crisis of the Phanerozoic. Yet, the environmental and geochemical conditions governing the crisis and ecosystem recovery remain debated.

MAVEN EUVM Data Products for Space Weather at Mars

open access: yesSpace Weather, Volume 24, Issue 2, February 2026.
Abstract Space weather monitoring is critical to protect not only our technological assets in space, but also mitigate disruptions to life and society that depends on these vulnerable assets. Significant attention and resources have been dedicated to space weather monitoring at Earth, but little attention to date has been paid to planetary space ...

Preventing financial ruin: How the West India trade fostered creativity in crisis lending by the Bank of England

open access: yesThe Economic History Review, Volume 79, Issue 1, Page 57-88, February 2026.
Abstract This paper contributes to the understanding of the complex relationship between British economic performance during the Napoleonic wars and the ‘West Indies’, as the Caribbean slave colonies were called. Not only did profits from slave‐based commerce provide financing for the growth of the financial sector, as has been claimed, but the risk of

Report of the panel on volcanology, section 4 [PDF]

open access: yes
Two primary goals are identified as focal to NASA's research efforts in volcanology during the 1990s: to understand the eruption of lavas, gases, and aerosols from volcanoes, the dispersal of these materials on the Earth's surface and through the ...

How Early Trauma Shapes CEO Risk Appetite for Public Debt Versus Bank Debt

open access: yesFinancial Review, Volume 61, Issue 1, Page 39-58, February 2026.
ABSTRACT This study examines the impact of CEOs’ early disaster experiences on the choice of debt structure. We find that firms led by CEOs who have endured disasters are more inclined to shift from bank debt to public debt. This evidence remains robust across various alternative measures, empirical specifications, and identification tests aimed at ...

Tracking Subsurface Changes via Frequency Shifts in Volcanic Tremor Spectral Lines: Observations From Mt Etna

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Episodes of volcanic tremor provide valuable insights into the dynamics of subsurface processes at active volcanoes. Previous studies have suggested that evolving tremor properties may relate to changes in the stress conditions of the plumbing system. However, a strong causative link has remained elusive.
