Nanoscale space weathering features in mature lunar soil revealed by TEM and APT
Meteoritics &Planetary Science, EarlyView.Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

The Astrophysical JournalWe present new results from the ASTRID simulation from z = 3 to z = 0.5, covering the epoch of cosmic noon. The galaxy stellar mass function, as well as the black hole mass and luminosity functions in ASTRID , exhibit good agreement with recent ...

The SVP–FRO6 Module Integrates the Control of Leaf Senescence and Flowering in Arabidopsis
Plant, Cell &Environment, EarlyView.ABSTRACT Plants coordinate major developmental transitions by integrating intrinsic genetic programs with environmental signals, where nutrient availability serves as a critical external factor shaping growth and fitness. Iron (Fe), an essential micronutrient for cellular respiration and photosynthesis, is strictly regulated through sophisticated ...

Galaxy quenching in various environments
, 2023 Already early studies of the morphology-density relation of galaxies showed that early-type galaxies lie in the centres of rich clusters, and in small groups in filaments between clusters, where they are located closer to filament axis than late-type galaxies. This means that galaxies are indeed pre-processed in groups. In our present study we searched

Enantioselective Separation and Negative Transport of Chiral Particles via Optical Needle Fields
Nanophotonics, Volume 15, Issue 13, 13 July 2026.This work proposes an all‐optical strategy that leverages a tailored optical needle field for the enantioselective separation and 3D manipulation of chiral particles. By introducing phase modulation, we engineer a dual‐needle configuration capable of spatially separating and negatively transporting both enantiomers within a single system, offering a ...

THE MASS DEPENDENCE OF DWARF SATELLITE GALAXY QUENCHING [PDF]
The Astrophysical Journal, 2014 We combine observations of the Local Group with data from the NASA-Sloan Atlas to show the variation in the quenched fraction of satellite galaxies from low mass dwarf spheroidals and dwarf irregulars to more massive dwarfs similar to the Magellanic clouds.

Revealing the Impact of Critical Stellar Central Density on Galaxy Quenching through Cosmic Time
The Astrophysical JournalIn a previous work, we investigated the structural and environmental dependence on quenching in the nearby universe. In this work, we extend our investigations to higher redshifts by combining galaxies from the Sloan Digital Sky Survey and The FourStar ...
