Advanced Materials, EarlyView.Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐

Investigating MAXI J1752–457 with NuSTAR in the Aftermath of a Superburst
The Astrophysical JournalWe present two NuSTAR observations of the X-ray transient, MAXI J1752−457, following a superburst that was observed by MAXI/Gas Slit Camera (GSC) in 2024 November.

Life‐Like Ferrous Oxide Microspheres from Kombucha
Advanced Materials Interfaces, EarlyView.Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

On spectra of X-ray bursters in the expansion phase
The Astrophysical Journal, 1991 Two alternative approaches to the theoretical description of spectra of X-ray bursters showing radial expansion near the light curve maximum are presented. The first one, using the LTE assumption, enables us to explain the noticeable soft excess which is present in corresponding EXOSAT observations.

Discovery of a Long Thermonuclear X-Ray Burst from the Ultracompact Binary 4U 1850–087
The Astrophysical JournalWe report the detection of a long X-ray burst from the ultracompact binary 4U 1850–087. The type I X-ray burst was observed on MJD 60171.65 by the Monitor of All-sky X-ray Image and Neutron Star Interior Composition Explorer (NICER). We analyze the NICER
