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 ...

No Redshift Evolution in the Fe ii/Mg ii Flux Ratios of Quasars across Cosmic Time

The Astrophysical Journal
The Fe ii /Mg ii emission line flux ratio in quasar spectra serves as a proxy for the relative Fe to α -element abundances in the broad-line regions of quasars.

Recent Progress and Future Prospects of LWIR T2SL InAs/GaSb Detectors on GaAs

Advanced Photonics Research, Volume 7, Issue 7, July 2026.
InAs/GaSb LWIR type‐II superlattices (T2SLs) on GaAs substrates are cost‐effective and offer higher yield. However, due to a relatively large lattice mismatch, a high density of threading dislocations is created, which is detrimental to device performance.

The Structure Function of Mid-infrared Variability in Low-redshift Active Galactic Nuclei

The Astrophysical Journal, 2023
Using the multi-epoch mid-infrared (MIR) photometry from the Wide-field Infrared Survey Explorer spanning a baseline of ∼10 yr, we extensively investigate the MIR variability of nearby active galactic nuclei (AGNs) at 0.15 < z < 0.4.

A Circuit of Mechanically Regulated Transcription Factors Balances Regenerative and Fibrotic Memory of Mesenchymal Stromal Cells

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Producing MSCs on rigid culture substrates induces a scar‐making phenotype, jeapordizing therapeutic success. ‘Tissue‐soft’ surfaces prevent MSC fibrogenesis and preserve regenerative traits. An epigenetic network, driven by HOXA11 and SALL1, maintains ‘soft memory’ by keeping chromatin open in relaxed MSCs, promoting anti‐fibrotic programs.

THE NUCLEAR INFRARED EMISSION OF LOW-LUMINOSITY ACTIVE GALACTIC NUCLEI [PDF]

, 2012
We present high-resolution mid-infrared (MIR) imaging, nuclear spectral energy distributions (SEDs), and archival Spitzer spectra for 22 low-luminosity active galactic nuclei (LLAGNs; L bol ≲ 10 42 erg s -1).

Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized
