Impact of global cooling on Early Cretaceous high pCO2 world during the Weissert Event [PDF]
Nature Communications, 2021 Modelling and sea surface temperature proxy data from the Weddell Sea document a 3–4 °C drop coinciding with the Early Cretaceous Weissert Event. Temperature data worldwide confirm a 3.0 °C global mean surface cooling, equivalent to a ~40% drop in ...

THE VALANGINIAN WEISSERT OCEANIC ANOXIC EVENT RECORDED IN CENTRAL-EASTERN SARDINIA (ITALY) [PDF]
Rivista Italiana di Paleontologia e Stratigrafia, 2018 Investigations on the S’Ozzastru section from the northern part of the Mt Albo area (central-eastern Sardinia, Italy) for integrated litho- bio- and chemostratigraphy allowed the identification of the Valanginian Weissert Oceanic Anoxic Event (OAE ...

Disruption of ATP Synthase Spatiotemporal Organization, Ca<sup>2+</sup> Dynamics, and Contractile Function in Senescent Cardiomyocytes. [PDF]
Aging CellEnhanced ATP hydrolysis, ΔΨm flickering, and destabilized ATP synthase dimers collectively reduce ATP availability in senescent cardiomyocytes. This energy deficit is associated with disrupted Ca2⁺ dynamics and contractility. ABSTRACT Heart disease is the leading cause of death in the elderly population.

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Geophysical Monograph Series, Page 247-262., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

New insights into the early Bajocian (Middle Jurassic) carbon cycle perturbation
Sedimentologika, 2023 Mesozoic strata record numerous negative and positive carbon isotope excursions (CIEs). The Middle Jurassic records a negative ~0.5 ‰ CIE at the Aalenian-Bajocian boundary followed by a positive ~1.5 ‰ CIE covering the entire early Bajocian.
