Red to Green: A Lipid Biomarker Record of Tonian‐Ediacaran Algae in Siberia

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

Thallium Isotopes Across the Smithian‐Spathian Boundary: Evidence for Anoxia Throughout Most of the Early Triassic

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Following the largest known Phanerozoic extinction, the end‐Permian mass extinction, the Early Triassic is often considered an interval of slow biotic recovery. During this time, the minor Smithian‐Spathian extinction occurred, further delaying the biotic recovery of this epoch.

Israel's Netanyahu Trap

Middle East Policy, Volume 33, Issue 3, Autumn (Fall) 2026.
Abstract On February 28, 2026, a major regional war broke out involving the United States, Israel, and Iran. While the theory of structural realism considers this conflict the product of shifting power dynamics, this article argues that it is better explained by what we term diversionary rhetorical entrapment.

Uranium: indispensable aujourd'hui, incontrôlable demain ?

Ni le plus abondant de la croûte terrestre, ni le plus rare non plus. Et pourtant, l’uranium occupe une place à part dans notre imaginaire collectif. Derrière cet atome se cache un pouvoir de fascination singulier.
