Unravelling echinoid mass mortalities: a global overview of mechanisms, spatio‐temporal trends, and taxonomic insights

open access: yesBiological Reviews, Volume 101, Issue 1, Page 221-236, February 2026.
ABSTRACT Mass mortality events (MMEs) have been occurring since the dawn of time. However, in contrast to terrestrial events, most marine MMEs remain undetected, largely due to the inaccessibility of many marine environments. One of the most notorious and best‐studied marine MMEs in modern times is that of the population collapse of the echinoid ...

FAM20A Deficiency Drives Transcriptomic Dysregulation and Functional Impairment in Gingival Fibroblasts

open access: yesCell Proliferation, Volume 59, Issue 2, February 2026.
FAM20A variants cause AI1G, marked by enamel defects, gingival overgrowth and ectopic calcifications. RNA sequencing of patient‐derived gingival fibroblasts showed dysregulated genes in adhesion, proliferation and signalling pathways. Functional assays revealed increased cell proliferation, impaired ECM interactions and osteogenesis, suggesting FAM20A ...

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

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 ...

The Subgingival Host–Microbial Landscape in Mothers With Periodontitis and Their At‐Risk Offspring

open access: yesJournal of Clinical Periodontology, Volume 53, Issue 2, Page 201-213, February 2026.
ABSTRACT Aim To evaluate the subgingival proteome and microbiome of mothers with periodontitis and their offspring, thereby assessing signatures of periodontal diseases. Methods Forty participants in four groups were included: mothers with periodontitis and their offspring, as well as periodontally healthy mothers and their offspring.

Magnetostratigraphy and Source Characterisation Across the Early Miocene Unconformity, Northern Rocky Mountains, USA

open access: yesTerra Nova, Volume 38, Issue 1, Page 1-8, February 2026.
ABSTRACT The early Miocene unconformity (EMU) formed during a transition in the tectonic regime of western North America that coincided with faunal diversification. The Railroad Canyon section in the northern Rocky Mountains provides a complete geologic record around this event. Our new magnetostratigraphic study in combination with published U‐Pb ages

Seismological Evidence of Multiple Crustal Magma Reservoirs Beneath Mt. Wrangell in Southcentral Alaska

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Recent studies have challenged the classical view of magma chambers as ephemeral, melt‐rich bodies confined to shallow depths beneath arc volcanoes at subduction zones. Instead, increasing evidence supports the existence of long‐lived, vertically extensive magmatic systems with persistent partial melts within the crust. Nevertheless, the depth
