Abstract The successful return of the OSIRIS-REx Sample Return Capsule (SRC) in September 2023 has provided the planetary science community with an unprecedented reservoir of pristine extraterrestrial material. Analysis of the 121.6 grams of regolith from asteroid (101955) Bennu has revealed a celestial body of immense chemical complexity: a carrier of ancient presolar grains derived from supernovae, a host to water-soluble magnesium-sodium phosphates indicative of a paleoceanic past, and a...

Abstract The preservation of cognitive function in the aging human brain represents one of the paramount challenges of modern biomedical science. For decades, the central nervous system (CNS) was regarded as a fortress of "immune privilege," isolated from the systemic clearance mechanisms that maintain homeostasis in peripheral tissues. This paradigmatic view has been dismantled by the recent characterization of the glymphatic system—a glial-dependent perivascular network for waste...

1. Introduction: The Archipelagic Laboratory 1.1. Zealandia as an Evolutionary Crucible The submerged continent of Zealandia, Te Riu-a-Māui, represents one of the Earth's most significant yet enigmatic biological provinces. Separated from the supercontinent Gondwana approximately 80 million years ago, this continental fragment drifted into the isolation of the South Pacific, carrying with it a cargo of ancient lineages that would evolve in splendid seclusion. 1  While often characterized by...
