DHCR24 Alleviates DNA Damage in Senescent Vascular Endothelial Cells via ENKUR/Ca2+ Signaling
In senescent vascular endothelial cells, DHCR24 deficiency triggers ENKUR‐dependent Ca2+ overload, which in turn induces endoplasmic reticulum stress and mitochondrial dysfunction, ultimately exacerbating oxidative stress and DNA damage. ABSTRACT DNA damage is considered one of the major contributors to aging.

Integrated detrital zircon U–Pb, Nd–Sr isotopes and thermochronology record western Indian‐margin provenance reorganisation. Late Cretaceous–Palaeocene sediment supply was Indian‐affinity; Asian‐affinity input appeared across the Palaeocene–Eocene transition (~56.5–54.7 Ma), suggesting India–Asia collision was underway, while mixed provenance persisted

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

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.

Key Points Measurement of 86Sr at count rates < 1500 cps can result in statistical bias. Non‐linear signals in analogue detection mode (e.g., Rb) present a challenge for accurately dating high 87Rb/86Sr mica (> 1000). Accounting for these considerations, high 87Rb/86Sr mica are dated here with accuracies of ∼ 1%.
