    Published 2024-12-01
    “…We estimate ice-volume driven (barystatic; BSL) sea-level changes for the Cenozoic using new Mg/Ca data from 58 to 48 Ma and a revised analysis of Mg/Ca trends over the past 66 Myr. We combine records of BSL, temperature-driven sea level, and long-term ocean basin volume variations to derive a new global mean geocentric sea level (GMGSL; “eustatic”) estimate. …”

    Life in the Bubble: How a Nearby Supernova Left Ephemeral Footprints on the Cosmic-Ray Spectrum and Indelible Imprints on Life by Caitlyn Nojiri, Noémie Globus, Enrico Ramirez-Ruiz

    Published 2025-01-01
    “…The ^60 Fe peak deposits found in the deep-sea crust have been interpreted by the imprints left by the ejecta of supernova explosions occurring about 2–3 and 5–6 Myr ago. It is likely that the ^60 Fe peak at about 2–3 Myr originated from a supernova occurring in the Upper Centaurus Lupus association in Scorpius Centaurus (≈140 pc) or the Tucana-Horologium association (≈70 pc), whereas the  ≈5–6 Myr peak is likely attributed to the solar system's entrance into the bubble. …”

    Published 2025-01-01
    “…Using recent discoveries of GC streams from Gaia Data Release 3, we present, for the first time, a catalog of directly observed mass-loss rates for 12 Galactic GCs, ranging from 0.5 to 200 M _⊙ Myr ^−1 . By fitting power-law relations between the mass-loss rate and key GC properties, we identify positive correlations with GC mass and orbital frequency, consistent with the predictions from N -body simulations.…”
