JWST Imaging of the Closest Globular Clusters—VI. The Lowest‐Mass Objects in M 4 and the Galactic Bulge

Astronomische Nachrichten, Volume 346, Issue 9, November 2025.
ABSTRACT We present James Webb Space Telescope observations of M 4—the closest globular cluster—that probe the lower Main Sequence down to the hydrogen‐burning limit. The unveiled stellar sequence reaches much fainter luminosities than previously possible, revealing a few extremely red objects that are consistent with brown dwarfs as cool as Teff∼1000K$

A Coherence Theory of Jurisprudence in the Spirit of Jhering: A Restatement, Update, and Defence of Jhering’s Early Methodology

Ratio Juris, Volume 38, Issue 3, Page 198-235, November 2025.
Abstract This essay revisits the early methodology of Rudolph von Jhering. It has often been dismissed due to its heavy metaphysics, unwieldy presentation, and alleged neglect of teleology. But a charitable reconstruction in contemporary terms reveals a coherence theory of jurisprudence that is in many ways superior to current coherence accounts.

HEAD IN THE STARS, FEET ON THE GROUND: Scale and Astronomy Initiatives in Southern Africa

Cultural Anthropology, Volume 40, Issue 4, Page 571-596, November 2025.
ABSTRACT This article explores the evolution of radio astronomy in South Africa and Madagascar, focusing on how “scale” functions as both a way of understanding the world and marking differences in existence. In outer space research, the ground is crucial but often overlooked.

Cosmological model-independent constraints on the baryon fraction in the IGM from fast radio bursts and supernovae data

European Physical Journal C: Particles and Fields, 2023
Fast Radio Bursts (FRBs) are millisecond-duration radio transients with an observed dispersion measure (DM) greater than the expected Milky Way contribution, which suggests that such events are of extragalactic origin.

Simultaneous inhibition of TRIM24 and TRIM28 sensitises prostate cancer cells to antiandrogen therapy, decreasing VEGF signalling and angiogenesis

Molecular Oncology, Volume 19, Issue 10, Page 2797-2821, October 2025.
TRIM24 and TRIM28 are androgen receptor (AR) coregulators which exhibit increased expression with cancer progression. Both TRIM24 and TRIM28 combine to influence the response of castrate‐resistant prostate cancer (CRPC) cells to AR inhibitors by mediating AR signalling, regulation of MYC and upregulating VEGF to promote angiogenesis. Castrate‐resistant

Mid-infrared Extinction toward the Galactic Center

The Astrophysical Journal
We determine the mid-infrared (MIR, ∼5–22 μ m) extinction toward the Galactic center using MIRI/Medium-Resolution Spectrometer (MRS) integral field unit observations of the central 3″ × 3″ region (near 5 μ m) to 7″ × 7″ region (near 22 μ m).

Phenotypic and Genetic Characterization and Production Abilities of Lacticaseibacillus rhamnosus Strain 484—A New Probiotic Strain Isolated From Human Breast Milk

Food Science &Nutrition, Volume 13, Issue 10, October 2025.
Human breast milk (HBM) is a recognized source of probiotic bacteria, with species such as Lacticaseibacillus rhamnosus demonstrating considerable potential for applications in both the medical and food industries. In this study, the probiotic potential of strain 484, isolated from HBM, was evaluated through comprehensive phenotypic and genetic ...

Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

Journal of Research in Science Teaching, Volume 62, Issue 8, Page 1902-1922, October 2025.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).
