The Ba Isotopic Ratio as a Way of Distinguishing the R- and S-Process in Chemical Evolution Models

Galaxies
Only recently, observational studies have started providing measurements for the barium isotopic ratio in metal-poor stars with unprecedented detail. This new approach can be extremely useful in tracing back the origin of neutron-capture elements, since ...

Homo Memorabiliaxis: Souvenirs and the Evolution of Autobiographical Memory and Self

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 4, December 2026.
ABSTRACT Humans routinely keep souvenirs objects retained for the memories they evoke, yet the evolutionary and cognitive consequences of mnemonic collecting remain unclear. Existing discussions of curated objects concentrate on later prehistory and modern humans and view such objects at the social level, as carriers of shared cultural meaning or as ...

Genome evolution of Mediterranean olives following DNA repeats diversification

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract The olive tree (Olea europaea L. subsp. europaea) is one of the most representative perennial crops of the Mediterranean Basin, yet the genomic processes underlying its domestication and diversification remain poorly understood. Here, we investigated repeatome variation across 20 accessions, including 11 wild oleasters and nine cultivated ...

Tracing the Galactic Origins of Selected Four G-type Stars in the Solar Neighborhood

The Astronomical Journal
We present a multimethod investigation of four metal-poor G-type main-sequence stars to resolve their Galactic origins. By combining high-resolution spectroscopy from PolarBase, photometric/astrometric data from Gaia DR3, and spectral energy distribution

Building a Continental‐Scale Geodetic Network: The Plate Boundary Observatory (PBO)

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract The Plate Boundary Observatory (PBO) transformed the use of geodesy in North America to study crustal deformation and plate boundary processes by establishing a continental‐scale, standardized, open‐access geodetic network. Built and operated by UNAVCO between 2003 and 2018 as part of the National Science Foundation (NSF)‐funded EarthScope ...

The Origin of Strong α-Element Bimodalities in FIRE Simulations of Milky Way–Mass Galaxies

The Astrophysical Journal
One of the Milky Way’s (MW) characteristic features is a strongly bimodal distribution of α -process elements, such as Mg, at fixed [Fe/H] in stellar abundances. We examine patterns in [Mg/Fe] versus [Fe/H] in FIRE-2 simulations of MW-mass galaxies.

Object Detection of Tree Uprooting Signatures in Gridded LiDAR Elevation Data

Earth and Space Science, Volume 13, Issue 11, November 2026.
Abstract Tree uprooting (or tree throw) is a natural forest disturbance with consequences for ecology, pedology, hydrology, geomorphology, and atmospheric fluxes. These events leave topographic signatures in the form of pit‐mound couplets (PMCs) that persist for decades to centuries.
