Unveiling the Functional Role of KIF21B in Microglia Inflammatory Response
Glia, Volume 74, Issue 9, September 2026.Microglia express KIF21B in both sexes. KIF21B binds to microglia cytoskeleton; inflammation alters such interaction promoting a phagocytic state in females. In male microglia KIF21B modulates migration. ABSTRACT Microglia are brain immune cells that maintain homeostasis and respond to injury, changing cell morphology to drive inflammation, migration ...

On the Nature of Low‐Luminosity Narrow‐Line Active Galactic Nuclei [PDF]
The Astrophysical Journal, 2003 There is clear observational evidence that some narrow-line (type 2) active galactic nuclei (AGNs) have a hidden broad-line region (BLR) and are thus intrinsically broad-line (type 1) AGNs. Does this AGN unification apply for all type 2 AGNs? Indirect arguments suggest that some "true" type 2 AGNs, i.e., AGNs having no obscured BLR, do exist, but it is

Discovery of five low-luminosity active galactic nuclei at the centre of the Perseus cluster [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 According to optical stellar kinematics observations, an over-massive black hole candidate has been reported by van den Bosch et al. (2012) in the normal early-type galaxy NGC 1277. This galaxy is located in the central region of the Perseus cluster. Westerbork Synthesis Radio Telescope (WSRT) observations have shown that NGC 1277 and other early-type ...

Evidence of a Forming Nucleus in the Fourcade–Figueroa Galaxy
The Astrophysical JournalWe analyze data from the IRAS, Wide-field Infrared Survey Explorer, and Planck satellites, revealing an unresolved dust condensation at the center of the Fourcade–Figueroa galaxy (ESO270-G017), which may correspond to a forming nucleus.

The Gamma Factory: A New Experimental Paradigm for the Post‐HL‐LHC Era
Annalen der Physik, Volume 538, Issue 8, August 2026.ABSTRACT The Gamma Factory (GF) proposal is motivated by the recognition of a largely untapped potential of the CERN accelerator complex to enable a new research program at the intersection of particle, nuclear, atomic, fundamental, and applied physics. These fields could benefit from novel experimental tools made possible by a future GF facility.

A Candidate for the Least-massive Black Hole in the First 1.1 Billion Years of the Universe
The Astrophysical Journal Letters, 2023 We report a candidate of a low-luminosity active galactic nucleus (AGN) at z = 5 that was selected from the first near-infrared images of the JWST CEERS project.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

Chemogenetic Activation of G12 Signaling Thickens the Epidermis With Enhanced Barrier Function
FASEB BioAdvances, Volume 8, Issue 8, August 2026.In this study, we investigated the role of G12 signaling in the epidermis using a keratinocyte‐specific chemogenetic approach. Activation of G12 signaling promoted keratinocyte differentiation and enhanced epidermal barrier function by upregulating filaggrin, claudin‐1, and ceramide.
