Is Soil Fertility the Cause or the Effect of Land Invasion by Prosopis?

Journal of Plant Nutrition and Soil Science, Volume 188, Issue 2, Page 232-240, April 2025.
ABSTRACT Background For 20 years, Prosopis juliflora is aggressively spreading throughout the “Njemps Flats” in Kenya, where it changes vegetation cover and affects pastoral livelihoods. Its invasion dynamics is related to shallow groundwater tables (Prosopis being a phreatophyte), and it reportedly preferentially colonizes sites with favourable soil ...

Fibrinogen‐binding M‐related proteins facilitate the recruitment of plasminogen by Streptococcus pyogenes

Protein Science, Volume 34, Issue 4, April 2025.
Abstract Group A Streptococcus (GAS) M‐related proteins (Mrp) are dimeric α‐helical coiled‐coil cell‐wall‐attached proteins. During infection, Mrp recruit human fibrinogen (Fg) to the bacterial surface, enhancing phagocytosis resistance and promoting growth in human blood.

Cosmology with Galaxy Photometry Alone

The Astrophysical Journal Letters
We present the first cosmological constraints using only the observed photometry of galaxies. Villaescusa-Navarro et al. recently demonstrated that the internal physical properties of a single simulated galaxy contain a significant amount of cosmological

UVSat: a concept of an ultraviolet/optical photometric satellite

, 2017
Time-series photometry from space in the ultraviolet can be presently done with only a few platforms, none of which is able to provide wide-field long-term high-cadence photometry.

Review of asteroid, meteor, and meteorite‐type links

Meteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.

Changes in kidney functions following acute infusion of low molecular weight polyvinylpyrrolidone in male rats

Physiological Reports, Volume 13, Issue 7, April 2025.
Abstract Polyvinylpyrrolidone (PVP), a water‐soluble homopolymer, has been widely used in food, beverage, medical, and experimental tissue preparations. However, the effect of PVP on renal functions remains unknown. We investigated the acute administration of low MW of PVP on renal functions and whether it produces a toxic effect on the kidney.
