Skeletal Muscle Mitochondria Contain Nuclear‐Encoded RNA Species Prior to and Following Adaptation to Exercise Training in Rats

The FASEB Journal, Volume 39, Issue 13, 15 July 2025.
Here, we report that mitochondria from rat skeletal muscle contain a select population of nuclear‐encoded protein‐coding and noncoding RNAs, including 3 microRNAs whose expression tended to be altered by exercise training. These findings suggest that mitochondria‐localized nuclear‐encoded RNAs may play a role in mediating the beneficial adaptive ...

AhR‐Dependent Induction of β‐Defensin 1 in Colonic Epithelial Cells Regulates Cross‐Talk between Gut Microbiota and Immune Response Leading to Attenuation of Colitis

Advanced Science, Volume 12, Issue 25, July 3, 2025.
This study identifies a key signaling pathway involving the environmental sensor AhR and antimicrobial peptides, such as BD‐1, in the regulation of intestinal homeostasis. It highlights the role of BD‐1 in regulating gut microbiota and the intestinal immune response.

The Atacama Cosmology Telescope: Systematic Transient Search of Single Observation Maps

The Astrophysical Journal
We conduct a systematic search for astrophysical transients using data from the Atacama Cosmology Telescope. The data were taken from 2017 to 2022 in three frequency bands spanning 77 to 277 GHz.

Human γδ T Cell Function Is Impaired Upon Mevalonate Pathway Inhibition

Immunology, Volume 175, Issue 3, Page 300-322, July 2025.
Mevalonate pathway is important for the effector function of gammadelta T cells. Inhibition of the pathway in vivo and in vitro impairs cytokine and cytotoxic molecule production by mainly affecting protein prenylation and disturbing intracellular signalling in Vdelta2 T cells. Created with Biorender.

Sizes of Active Galactic Nucleus Inhomogeneous Disks—Large in Microlensing, Small in Reverberation Mapping

The Astrophysical Journal
Magnetohydrodynamic turbulence can drive significant temperature fluctuations in the accretion disk of an active galactic nucleus (AGN). As a result, the disk can be highly inhomogeneous and has a half-light radius larger than the static Shakura and ...

The NuSTAR X-ray spectrum of the low-luminosity active galactic nucleus in NGC 7213

, 2015
We present an analysis of the 3–79 keV NuSTAR spectrum of the low-luminosity active galactic nucleus NGC 7213. In agreement with past observations, we find a lower limit to the high-energy cut-off of E_c > 140 keV, no evidence for a Compton-reflected ...

Light Quantity Impacts Early Response to Cold and Cold Acclimation in Young Leaves of Arabidopsis

Plant, Cell &Environment, Volume 48, Issue 7, Page 5030-5052, July 2025.
ABSTRACT Plant reactions to stress vary with development stage and fitness. This study assessed the relationship between light and chilling stress in Arabidopsis acclimation. By analysing the transcriptome and proteome responses of expanding leaves subjected to varying light intensity and cold, 2251 and 2064 early response genes and proteins were ...
