Infrared emission from dust in the Coma cluster of galaxies

The Astrophysical Journal, 1990
Detailed calculations of the infrared emission from collisionally heated dust in the Coma cluster are presented. The proposed model includes continuous dust injection from galaxies, grain destruction by sputtering, and transient grain heating by the hot plasma.

Spectroscopic Evidence of Organic Molecules Released By the Dust of Halley’s Inner Coma [PDF]

International Astronomical Union Colloquium, 1991
Abstract New spectroscopic arguments supporting the probable presence of organic molecules in the material released by comet Halley are deduced from the data obtained by the Vega three-channel spectrometer. Two excesses of emission on the UV side of the OH and CN bands at 305 and 383 nm are interpreted as being due to “prompt” radiation emitted by ...

IL‐33/ST2 Signaling Sustains Hepato‐Intestinal Homeostasis by Orchestrating Vascular Surveillance and Immune Regulatory Circuits During Experimental Trypanosoma cruzi Infection

The FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Impairment of hepato‐intestinal homeostasis triggered by ST2 deficiency during T. cruzi infection. Within the splenic compartment, immune dysregulation is marked by a robust pro‐inflammatory polarization of the T‐cell landscape. In the liver, ST2 deficiency is associated with hepatocellular injury, increased parasite burden, and hyperalbuminemia ...

Decades of progress: Breeding modified soybean root systems

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Decades of soybean (Glycine max (L.) Merr.) breeding have delivered substantial yield gains, yet how root systems have changed over this period has remained unclear. We evaluated 24 maturity group IV soybean cultivars released between 1930 and 2005 in field experiments at two locations over 2 years, and quantified topsoil root and nodulation ...

Minor effect of physical size sorting on iron solubility of transported mineral dust [PDF]

, 2011
Observations show that the fractional solubility of Fe (FS-Fe, ratio of dissolved to total Fe) in dust aerosol increases dramatically from ~0.1% in regions of high dust mass concentration to 80% in remote regions where concentrations are low.

Rotating dust particles in the coma of comet 67P/Churyumov-Gerasimenko [PDF]

, 2015
Context. During September and October, 2014, OSIRIS cameras onboard ESA Rosetta mission detected millions of single particles. Many of these dust particles appear as long tracks (due to both the dust proper motion and the spacecraft motion during the ...

Lucy Mission Search Plans for Activity around Its Jovian Trojan Flyby Targets

The Planetary Science Journal
Activity in small bodies, defined here as the episodic or continuous release of material, was long thought to be exclusively a behavior of comets, but it has since been discovered in some centaurs, main-belt asteroids, and near-Earth asteroids.
