The Gas-phase Mass–Metallicity Relation for Massive Galaxies at z ∼ 0.7 with the LEGA-C Survey

The Astrophysical Journal
The massive end of the gas-phase mass–metallicity relation (MZR) is a sensitive probe of active galactic nuclei (AGN) feedback that is a crucial but highly uncertain component of galaxy evolution models.

Chemical analysis of the Milky Way’s nuclear star cluster

Astronomy & Astrophysics
Context. The Milky Way nuclear star cluster (MWNSC) is located in the Galactic centre, together with the Milky Way nuclear stellar disc (MWNSD), and they dominate the gravitational potential within the inner 300 pc.

Genome‐wide prediction of cloned disease resistance homologues across the Oryza genus

The Plant Genome, Volume 19, Issue 4, December 2026.
Abstract The wild relatives of rice (Oryza sativa L.) represent reservoirs of genetic diversity and potential sources of novel pest and disease resistance. The recent availability of high‐quality Oryza genome assemblies has enabled greater exploration of this diversity across the genus.

Milky Way’s Metal-poor Stars Display Chemical Transition near the Solar Radius

The Astrophysical Journal Letters
The metal-poor stars of a galaxy offer insights into that galaxy’s early formation processes and accretion history. Here, we investigate whether the metal-poor stars of our Milky Way Galaxy exhibit any characteristic trends in Galactocentric distance ...

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 ...

Subaru/HDS Abundances in Three Giant Stars in the Ursa Minor Dwarf Spheroidal Galaxy

, 2004
International audienceWith the HDS (High Dispersion Spectrograph) on the Subaru Telescope, we obtained high-resolution optical region spectra of three red giant stars (COS 4, COS 82, and COS 347) in the Ursa Minor dwarf spheroidal galaxy.

Liquid Biopsy: Past, Present, and Future

MedComm, Volume 7, Issue 11, November 2026.
Liquid biopsy has expanded from cancer genotyping to a broader strategy for probing both oncologic and nononcologic conditions through circulating analytes and multilayer molecular readouts. This review traces the field's past, present, and future—summarizing where liquid biopsy is most actionable today, why performance varies across contexts, and ...

PLANETARY NEBULAE IN THE INNER MILKY WAY: NEW ABUNDANCES

, 2010
The study of planetary nebulae in the inner-disk and bulge gives important information on the chemical abundances of elements such as He, N, O, Ar, Ne, and on the evolution of these abundances, which is associated with the evolution of intermediate-mass ...

The Impact of Initial Composition on Massive Star Evolution and Nucleosynthesis

The Astrophysical Journal
We study the sensitivity of presupernova evolution and supernova nucleosynthesis yields of massive stars to variations of the initial composition. We use the solar abundances from Lodders, and compute two different sets of initial stellar compositions ...

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection

Advanced Materials Technologies, Volume 11, Issue 20, 21 October 2026.
A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...
