Meteoritics &Planetary Science, Volume 60, Issue 3, Page 616-631, March 2025.Abstract Results of microanalysis study of NWA 869 meteorite, an ordinary chondrite, where silicates, Fe‐Ni alloys, and troilite are major constituents, are reported. The presented study of microtextures in metallic and sulfide grains provides information on processes occurring from the asteroid's accretion, through the impacts until cooling.

Meteoritics &Planetary Science, EarlyView.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 ...

Meteoritics &Planetary Science, EarlyView.Abstract We reevaluated pairing relationships among 56 Antarctic howardites, eucrites, and diogenites (HED) from the Miller Range ice fields (MIL) based on new measurements of cosmogenic radionuclides and bulk composition of 28 HED samples and one HED‐related dunite.

A feasibility assessment of micromill sampling for Rb‐Sr and Sm‐Nd geochronology of shergottites
Meteoritics &Planetary Science, EarlyView.Abstract Accurate dating of Martian meteorites is crucial for understanding key events in the planet's evolution. However, not all Martian meteorites are amenable to dating techniques currently in use for these rocks. The priority of sample preservation precludes mineral separation methods for low‐volume specimens, whereas the less destructive in situ ...

Marine Mammal Science, EarlyView.ABSTRACT The Australian fur seal (Arctocephalus pusillus doriferus, AUFS) population, currently less than 47% of its pre‐harvest size, represents the largest resident marine predator biomass in south‐eastern Australia. This region, characterized by low marine productivity and rapid warming, is home to Kanowna Island, the third‐largest AUFS colony ...

Visionaries and Crackpots, Maniacs and Saints: Existential Risk and the Politics of Longtermism
Ratio, EarlyView.ABSTRACT Despite advancing strong claims about our collective priorities, longtermism has received little attention in debates in political philosophy. I first provide an account of longtermism that highlights the way it departs from established work on intergenerational justice.

Risk Analysis, EarlyView.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.

Review of International Economics, EarlyView.ABSTRACT This study examines the impact of diplomatic realignments on bilateral trade flows in developing countries, focusing on nations that switched diplomatic allegiances from Chinese Taiwan to Mainland China between 1995 and 2019. Using aggregate bilateral trade data from Comtrade, the analysis uses a gravity model estimated with the Poisson pseudo‐

Sedimentology, EarlyView.ABSTRACT An investigation of allogenic forcings on shallow‐marine strata of the Miocene–Pliocene Kueichulin Formation, Taiwan Western Foreland Basin, reveals that shifts in palaeoenvironments were strongly controlled by: (1) orogenesis and basin subsidence, (2) precession‐driven hydroclimate and (3) obliquity‐driven atmospheric and ocean circulation ...
