JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon

The Astrophysical Journal Letters
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon—the peak of cosmic star formation history—appear disk-dominated, leaving the origin of the dense cores in their quiescent descendants unclear.

Plant‐Based Mycetoma Inhibitors Targeting the 50S Ribosomal Protein of Nocardia brasiliensis: In Silico Approach

ChemistrySelect, Volume 10, Issue 21, June 4, 2025.
In‐silico drug discovery pipeline for Mycetoma caused by Nocardia brasiliensis. A library of 1034 phytocompounds was screened to identify potent inhibitors, with Parviflorone F showing strong binding and stability against the 50S ribosomal unit. Molecular dynamics confirmed its inhibitory potential, offering a promising therapeutic candidate.

COUGS-DESI: A Catalog of Unusual Galaxies with polar Structures in the DESI Legacy Imaging Surveys

Astronomy & Astrophysics
Context. Polar-structure galaxies (PSGs) host photometrically and kinematically decoupled components oriented at large angles to one another. These systems, which include polar rings, polar disks, polar halos, polar bulges, polar dust lanes, and polar ...

Resolved properties of classical bulge and pseudo-bulge galaxies

Monthly Notices of the Royal Astronomical Society
ABSTRACT We compare properties of classical and pseudo-bulges and properties of their hosting galaxies selected from the MaNGA survey. Bulge types are identified based on the Sérsic index n of bulge component and the position of bulges on the Kormendy diagram.

Mesenchymal Stem Cells Prevent SLC39A14‐Dependent Hepatocyte Ferroptosis through Exosomal miR‐16‐5p in Liver Graft

Advanced Science, Volume 12, Issue 6, February 10, 2025.
In hepatic IRI, SLC39A14 is identified as a driver of hepatocyte ferroptosis through facilitating extracellular NTBI transported into hepatocytes. Furthermore, hBMSCs has a significant therapeutic effect against hepatic IRI. hBMSCs delivered exosomal miR‐16‐5p, which can specifically target the 3'UTR region of SLC39A14 mRNA, thereby inhibiting SLC39A14‐

A Perspective on the Milky Way Bulge Bar as Seen from the Neutron-capture Elements Cerium and Neodymium with APOGEE

The Astrophysical Journal
This study probes the chemical abundances of the neutron-capture elements cerium and neodymium in the inner Milky Way from an analysis of a sample of ∼2000 stars in the Galactic bulge bar spatially contained within ∣ X _Gal ∣ < 5 kpc, ∣ Y _Gal ∣ < 3.5 ...

JWST Imaging of the Closest Globular Clusters—V. The White Dwarfs Cooling Sequence of M4

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT We combine infrared (IR) observations collected by the James Webb Space Telescope with optical deep images by the Hubble Space Telescope taken ~20 years earlier to compute proper‐motion membership for the globular cluster (GC) M4 (NGC 6121) along its entire white dwarf (WD) cooling sequence (CS).

Revisiting Variable Stars Near Globular Clusters South of −29° Declination

Astronomische Nachrichten, Volume 346, Issue 2, February 2025.
ABSTRACT We review an often‐cited but seldom‐accessed catalogue by Fourcade and Laborde (1966) of 785 variable stars near 47 southern Galactic globular clusters, and recover the locations of 85 stars that were not incorporated into subsequent variable star catalogues and hence have become “lost” to the literature.

Assessment of SDSS-derived Galaxy Morphologies Using HST Imaging

The Astrophysical Journal
The Sloan Digital Sky Survey (SDSS) was foundational to the study of galaxy evolution, having revealed the bimodality of galaxies and the relationship between their structure and star-forming activity.
