GALAXY CLUSTERS DISCOVERED VIA THE SUNYAEV–ZEL'DOVICH EFFECT IN THE 2500-SQUARE-DEGREE SPT-SZ SURVEY [PDF]

, 2014
We present a catalog of galaxy clusters selected via their Sunyaev–Zel'dovich (SZ) effect signature from 2500 deg2 of South Pole Telescope (SPT) data. This work represents the complete sample of clusters detected at high significance in the 2500 deg2 SPT-

NNMT Orchestrates Metabolic‐Epigenetic Reprogramming to Drive Macrophage‐Myofibroblast Transition in Hypertrophic Scarring

Advanced Science, EarlyView.
In macrophage‐myofibroblast transition, upregulated NNMT depletes S‐Adenosylmethionine‌ (SAM) and nicotinamide adenine dinucleotide(NAD+), thereby triggering epigenetic reprogramming via Histone H3 Lysine 27 acetylation (H3K27ac) accumulation at the promoter region of master transcription factor Prrx1.

Evidence for a Redshifted Excess in the Intracluster Light Fractions of Merging Clusters at z ∼ 0.8

The Astrophysical Journal Letters
The intracluster light (ICL) fraction is a well-known indicator of the dynamical activity in intermediate-redshift clusters. Merging clusters in the redshift interval 0.18 < z < 0.56 have a distinctive peak in the ICL fractions measured between ∼3800 and

Unravelling the origin of large-scale magnetic fields in galaxy clusters and beyond through Faraday Rotation Measures with the SKA [PDF]

, 2014
We investigate the possibility for the SKA to detect and study the magnetic fields in galaxy clusters and in the less dense environments surrounding them using Faraday Rotation Measures.

COSMIC RAYS IN GALAXY CLUSTERS AND THEIR NONTHERMAL EMISSION [PDF]

, 2014
Radio observations prove the existence of relativistic particles and magnetic field associated with the intra-cluster-medium (ICM) through the presence of extended synchrotron emission in the form of radio halos and peripheral relics.

Clinically Inspired Multimodal Treatment Using Induced Neural Stem Cells‐Derived Exosomes Promotes Recovery of Traumatic Brain Injury through Microglial Modulation

Advanced Science, EarlyView.
This study explores the therapeutic potential of iNSC‐Exo via local and systemic delivery in TBI mice. It is found that iNSC‐Exo enhances NRXN signaling through Microglia_Nrg3 and Microglia_Rarb, effectively promoting functional and neurological recovery, suggesting a new therapeutic strategy for TBI. Abstract Traumatic brain injury (TBI) poses serious

A HIGH STELLAR VELOCITY DISPERSION AND ∼100 GLOBULAR CLUSTERS FOR THE ULTRA-DIFFUSE GALAXY DRAGONFLY 44 [PDF]

, 2016
Recently a population of large, very low surface brightness, spheroidal galaxies was identified in the Coma cluster. The apparent survival of these ultra-diffuse galaxies (UDGs) in a rich cluster suggests that they have very high masses. Here, we present

Diversity and Ecological Potentials of Marine Viruses Inhabiting Continental Shelf Seas

Advanced Science, EarlyView.
To the best of the knowledge, this study provides the largest viral genome dataset from a continental shelf sea. It reveals that over half of vOTUs are novel, highlighting the remarkable viral novelty in the eastern continental shelf seas of China (ECSSC).
