Discovery of Giant Bubbles in the Hot Gaseous Halo of the Massive Disk Galaxy NGC 6286

The Astrophysical Journal
Based on archival Chandra X-ray observation, optical integral-field spectroscopic data, and radio interferometric data, we report the discovery of a pair of giant bubbles (with a projected radius ∼5 kpc) of ionized gas emerging from a highly inclined ...

A DEEP CHANDRA OBSERVATION OF THE X-SHAPED RADIO GALAXY 4C +00.58: A CANDIDATE FOR MERGER-INDUCED REORIENTATION? [PDF]

The Astrophysical Journal, 2010
Although rapid reorientation of a black hole spin axis (lasting less than a few Myr) has been suggested as a mechanism for the formation of wings in X-shaped radio galaxies (XRGs), to date no convincing case of reorientation has been found in any XRG. Alternative wing formation models such as the hydrodynamic backflow models are supported by observed ...

MUC1 as a Survival Effector of Radiotherapy‐Induced Epithelial Hybrid States in Basal‐Like Breast Cancer

International Journal of Cancer, Volume 159, Issue 5, Page 1296-1310, 1 September 2026.
Basal‐like breast cancer (BLBC) is aggressive and often exhibits inherent or acquired resistance to radiotherapy (RT), a primary treatment option. RT resistance is underpinned by molecular alterations, many of which are poorly understood. Here, RT‐induced transcriptomic changes were analyzed using bulk and spatial sequencing in a BLBC mouse model and ...

Jet Interaction with Galaxy Cluster Mergers

The Astrophysical Journal
Active galactic nucleus (AGN) bubbles in cool-core galaxy clusters are believed to facilitate the transport of cosmic-ray electrons (CRe) throughout the cluster.

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis

Plant, Cell &Environment, Volume 49, Issue 9, Page 7191-7209, September 2026.
ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

Low Frequency Extensions of Cyclotron Maser Instability‐Generated Radio Emission: A Statistical View From Cassini at Saturn

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract The Cassini spacecraft spent 13 years orbiting Saturn, quasi‐continuously measuring Saturn's radio emissions. One of the key elements of the radio spectrum at Saturn is the Saturn Kilometric Radiation (SKR), and several studies have been written on events called Low Frequency Extensions (LFEs) which represent strong, continuous extensions of ...

Blackbody Quasar and Radio Source (BBQSORS): A Candidate of Transitional Little Red Dots with a T ∼ 104 K Blackbody Spectrum

The Astrophysical Journal Letters
JWST surveys have identified a new class of active galactic nuclei (AGNs) called little red dots (LRDs). Their observational properties challenge the canonical AGN paradigm and provide key insights into the early growth phase of the supermassive black ...

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.
