Journal of Raman Spectroscopy, EarlyView.This study presents a hierarchical Raman‐based classification model for determining the elemental composition of garnets within complex solid‐solution systems. The workflow combines spectral preprocessing, dimensionality reduction, and two‐level classification: first distinguishing between pyralspite and ugrandite groups, and then classifying ...

Current understanding of electroautotrophy and its relevance in astrobiology‐related research
mLife, EarlyView.Abstract Electroautotrophy—the use of extracellular electrons as the primary energy source for autotrophic metabolism—remains understudied compared to photoautotrophy and chemoautotrophy. Its occurrence in deep‐earth and deep‐sea environments suggests profound implications for astrobiology, yet electroautotrophic microorganisms remain poorly explored ...

Frontiers in Astronomy and Space Sciences, 2020 Icy moons in our solar system are targets of interest to search for signs of life and habitability beyond Earth. They are the astrobiological aim for several developing space missions (JUICE, Europa Clipper, and Europa Lander). A further understanding of

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab
Symbolic Interaction, EarlyView.How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Biodiversity–food trade‐offs when agricultural land is spared from production
American Journal of Agricultural Economics, EarlyView.Abstract Biodiversity conservation in agricultural landscapes, the world's predominant land use, could involve sparing, or setting aside, agricultural land from production, implying biodiversity–food trade‐offs. Employing bird species and agricultural data in two panel data sets, we evaluate the extent of set‐aside's trade‐offs in England between 1992 ...

A 3200‐year weathering record of the Mekong River basin by sediments from the South China Sea
Boreas, EarlyView.The Mekong River is a mega‐river in East and Southeast Asia, and precipitation in its watershed influences more than 300 million people. However, the controlling factor in precipitation and weathering in the basin remains controversial. Here we present a high‐resolution record of weathering of the Mekong River basin over the past 3200 years by ...

The Astrophysical JournalPlanets orbiting in the habitable zones of white dwarfs have recently been proposed as promising targets for biosignature searches. However, since the white dwarf habitable zone resides at 0.01–0.1 au, planets residing there are subject to tidal heating ...

Fraternal cooperation of hierarchical cancer parallels metazoan multicellularity and eusociality
Biological Reviews, EarlyView.ABSTRACT Metazoan multicellularity and eusociality — both outcomes of the fraternal major transitions — have numerous features in common such as uneven distribution of group‐establishing potential. In addition to this framework, I argue herein that the group‐forming principles of metazoan multicellularity and eusociality are analogous to hierarchical ...
