ABSTRACT The interplay between diet, gut microbiota, and host immunity is central to food science. The Lachnospiraceae family ferments dietary fibers to produce short‐chain fatty acids (SCFAs), notably butyrate and propionate, with immunomodulatory potential. This critical review distinguishes established findings from hypotheses.

The nature of the X-ray transient MAXI J0556−332 [PDF]
Phase-resolved spectroscopy of the newly discovered X-ray transient MAXIJ0556-332 has revealed the presence of narrow emission lines in the Bowen region that most likely arise on the surface of the mass donor star in this low-mass X-ray binary.

Quantifying Deep Ocean Methane Along the Central Chilean Margin
Abstract Cold seeps are dynamic seafloor environments that provide conduits for methane (CH4) to be transferred from marine sediments to the global ocean and, in shallow settings, the atmosphere. These seeps are ubiquitous along continental margins yet their spatial extent and impact on the marine carbon cycle are poorly constrained.

Infrared/optical-X-ray simultaneous observations of X-ray flares in GRB 071112C and GRB 080506 [PDF]
Aims. We investigate the origin of short X-ray flares which are occasionally observed in early stages of afterglows of gamma-ray bursts (GRBs). Methods.

Quasi‐Homologous Solar Flares and Impacts on Thermospheric Density and Satellite Orbital Drag
Abstract Quasi‐Homologous Flaring (QHF) activity from active regions on the Sun releases intense electromagnetic radiation in recurrent bursts over extended periods. In this letter, we present the effects of recurrent impulsive extreme ultraviolet (EUV) heating on thermospheric neutral density and the resulting atmospheric drag on satellites based on ...

Determination of the length of coronal loops from the decay of X-ray flares
. We illustrate a procedure to estimate the length of stellar coronal loops from the decay of X-ray flares observed with ROSAT/PSPC. As we did in the first paper of this series for solar flares, we use extensive hydrodynamic modeling, and the synthesis ...
