Cell Proliferation, Volume 59, Issue 10, October 2026.Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

Exploring the Origin of Rejuvenating Gas from MaNGA Nearby Galaxies
The Astrophysical JournalThis study investigates the origin of secondary star formation, i.e., rejuvenation in nearby galaxies. From the Mapping Nearby Galaxies at APO integral field unit survey, we use stellar absorption features, D _n 4000 and EW(H δ _A ), to identify regions ...

Meteoritics &Planetary Science, Volume 61, Issue 10, Page 2445-2465, October 2026.Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

An improved model of chemical evolution within the Milky Way galaxy
, 2016 This thesis project involves the improvement of existing computer code, which is used in modeling the galactic chemical evolution (GCE) of the Milky Way Galaxy. The ultimate goal of a GCE analysis is to reliably predict abundances for all observationally

The Astrophysical JournalWe present an analysis of the effects of spectral resolution and aperture scale on derived galaxy properties using far-ultraviolet (FUV) spectra of local star-forming galaxies from the International Ultraviolet Explorer ( R ∼ 250, field of view (FOV ...

Genome architecture modulates 35S and 5S rDNA homogenization in Asteraceae
The Plant Journal, Volume 128, Issue 2, October 2026.SUMMARY Concerted evolution is the model by which multicopy gene families are homogenized across genomes, with ribosomal DNA (rDNA) as its textbook example. However, the extent and efficiency of this process may vary depending on genomic factors. The plant family Asteraceae provides a natural comparative system to address the evolutionary dynamics of ...

Tracing the early Milky Way thin disc with the Gaia-ESO Survey
Astronomy & AstrophysicsContext. The origin of metal-poor stars on thin-disc-like orbits remains an open question in Galactic archaeology, with the potential to provide important constraints on the earliest phases of Milky Way disc formation.

The Astrophysical JournalGas accretion from both the circumgalactic medium (CGM)/intergalactic medium (IGM) and interacting companion galaxy can dilute the gas phase metallicity of a galaxy. However, their relative contribution to the chemical evolution of galaxies remains to be

The effects of yields from binary massive stars as functions of metallicity
Astronomy & AstrophysicsThe evolution of massive stars in binary systems that undergo mass transfer during their lifetime is different from that of single stars. This might affect their chemical yields.
