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 ...

Star formation at the edge of galaxies [PDF]

openAt the edge of galaxies, in the lowest surface brightness regimes, lies the boundary where gas can collapse to form new stars. These regions remain largely unexplored due to the lack of very deep images that allow us to characterize the star-forming ...

Nature's Complexity Alive: Farewell to Several Unificatory Cosmological Arguments for Monism

Noûs, EarlyView.
ABSTRACT Throughout history, numerous thinkers have claimed that monism—in the form of priority monism, existence monism, monotheistic monism, or versions that posit an extra‐cosmic ultimate being—theoretically surpasses pluralism, above all by positing a unified universe.

Do spiral arms enhance star formation efficiency?

Spiral arms, as those of our own Milky Way, are some of the most spectacular features in disc galaxies. It has been argued that star formation should proceed more efficiently in spiral arms as a result of gas compression.

Harnessing Bulk‐Segregant Mapping to Identify Trait‐Associated Genes in the Allopolyploid Model Plant Nicotiana benthamiana

Plant Biotechnology Journal, EarlyView.
ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...

Star-formation in cosmic-dawn galaxies

In the first two years of operation JWST has delivered key new insights into the formation and evolution of galaxies in the early Universe. By combining imaging with spectroscopy, we discovered and characterised the first generation of galaxies, probing the Universe at an age of 300 million years. While the current JWST observations confirm the overall

Inefficient star formation in extremely metal poor galaxies

, 2014
The first galaxies contain stars born out of gas with few or no 'metals' (that is, elements heavier than helium). The lack of metals is expected to inhibit efficient gas cooling and star formation(1,2), but this effect has yet to be observed in galaxies ...

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 ...

How Many Worlds Could There Be? David Lewis and Advanced Modalizing

Analytic Philosophy, EarlyView.
ABSTRACT Advanced modalizing, namely, possibilities and necessities concerning modal space itself, is problematic for a Lewis‐style analysis of modality. A popular solution, proposed by Divers, postulates explicit semantic clauses for a collapse of advanced modalizing, to the conclusion that all such matters are, if true in the first place, both ...

Is Less More? Field Evidence on the Impact of Anti‐Bribery Policies on Employee Knowledge and Corrupt Behavior

Regulation &Governance, EarlyView.
ABSTRACT Companies increasingly adopt internal norms to enhance compliance with legal rules. However, the rapid growth in volume and complexity of such internal rules may obstruct employee knowledge and understanding of such internal rules, and therefore also their compliance.
