Advanced Science, EarlyView.The DNA demethylase TET3 drives lipid metabolic reprogramming in pancreatic ductal adenocarcinoma via a non‐catalytic mechanism. TET3 recruits histone deacetylases to repress GATA6, sustaining lipogenic enzyme expression and ferroptosis resistance.

Obscuration-dependent evolution of Active Galactic Nuclei [PDF]
, 2015 We aim to constrain the evolution of AGN as a function of obscuration using an X-ray selected sample of $\sim2000$ AGN from a multi-tiered survey including the CDFS, AEGIS-XD, COSMOS and XMM-XXL fields.

One‐Size‐Fits‐All: A Universal Binding Site for Single‐Layer Metal Cluster Self‐Assembly
Advanced Science, EarlyView.A universal strategy enables the formation of single‐layer metal clusters (SLMC) across 21 elements by harnessing vacancy defects as binding sites. Crucially, synthesis occurs without reactive species, preventing site passivation and ensuring strong metal–surface bonding.

The Astrophysical Journal3C 264 is one of the few FRI radio galaxies with detected TeV emission. It is a low-luminosity active galactic nucleus (LLAGN) and is generally associated with a radiatively inefficient accretion flow (RIAF).

Active Galactic Nuclei as High Energy Engines [PDF]
, 1999 Active Galactic Nuclei are considered as possible sites of cosmic ray acceleration and some of them have been observed as high energy gamma ray emitters (Blazars). There naturally comes an appealing idea that the acceleration of the highest energy cosmic

Advanced Science, EarlyView.Leukemic blasts induce membrane depolarization in mesenchymal stromal cells (MSCs), contributing to a dysfunctional niche that favors leukemia progression. Here, it is demonstrated that restoring the expression of CaV1.2 calcium channel in AML‐MSCs repolarizes their membrane potential, reprogramming them toward a healthy phenotype.

Search and Characterization of Remnant Radio Galaxies in the XMM-LSS Deep Field
The Astrophysical Journal, 2023 The remnant phase of a radio galaxy is characterized by the cessation of active galactic nuclei activity, resulting in the jets ceasing to feed plasma to the radio lobes.

Cluster magnetic fields from active galactic nuclei
, 2009 Active galactic nuclei (AGN) found at the centers of clusters of galaxies are a possible source for weak cluster-wide magnetic fields. To evaluate this scenario, we present 3D adaptive mesh refinement MHD simulations of a cool-core cluster that include ...

Deep Learning‐Assisted Coherent Raman Scattering Microscopy
Advanced Intelligent Discovery, EarlyView.The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

NuSTAR Observes Two Bulgeless Galaxies: No Hard X-Ray AGN Detected in NGC 4178 or J0851+3926
The Astrophysical Journal, 2023 The discovery over the last several decades of low- and moderate-luminosity active galactic nuclei (AGNs) in disk-dominated galaxies—which show no “classical” bulges—suggests that secular mechanisms represent an important growth pathway for supermassive ...
