The molecular phylogeny of Scirtinae based on ultraconserved elements is reanalyzed using the site‐heterogeneous model CAT‐GTR+G4. A new scirtine fossil, Serracyphon philipsi gen. et sp. nov., is reported from mid‐Cretaceous Kachin amber, and its placement is evaluated in light of the updated phylogenomic framework of Scirtinae.

Abstract Meteorite collection inventories show that many related meteorite groups have very different numerical abundances (e.g., lunar versus Martian meteorites; Eagle Station pallasites versus main‐group pallasites; eucrites versus diogenites; ungrouped Antarctic irons versus ungrouped non‐Antarctic irons; carbonaceous chondrite‐related (CC) iron ...

Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...

Abstract There are two separate conceptualizations for assessing existential risks: Planetary Boundaries (PBs) and global catastrophic risks (GCRs). While these concepts are similar in principle, their underpinning literatures tend not to engage with each other.
