Application of Neural Networks for Moon Near‐Surface Velocity‐Model Extraction

open access: yesGeophysical Prospecting, Volume 74, Issue 5, June 2026.
ABSTRACT Characterizing the shallow lunar subsurface is essential for future exploration activities, including landing‐site assessment, infrastructure construction and subsurface resource investigation. However, conventional seismic approaches for near‐surface characterization commonly depend on prior velocity information and assumptions regarding the ...

Anhydrous minerals in asteroid Bennu: Evidence for well‐preserved primordial components

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 6, Page 963-986, June 2026.
Abstract Aqueously altered carbonaceous astromaterials are dominated by secondary minerals, but a minor fraction of primary, anhydrous silicates and oxides escape alteration, offering insight into the original composition of asteroid parent bodies. We report the mineralogy, petrology, mineral chemistry, and oxygen isotopes of anhydrous minerals—50 ...

Low temperatures and high water/rock ratios in asteroid (101955) Bennu's history based on X‐ray powder diffraction of returned samples

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 6, Page 1077-1094, June 2026.
Abstract Samples returned by NASA's OSIRIS‐REx mission from the carbonaceous asteroid (101955) Bennu hold clues about conditions in the early solar system and the formation of planetary bodies. Initial investigation of Bennu samples found that they are rich in phyllosilicates and other secondary minerals formed during aqueous alteration of a larger ...

Homochirality through Photon-Induced Melting of RNA/DNA: the Thermodynamic Dissipation Theory of the Origin of Life

open access: yes, 2010
The homochirality of the molecules of life has been a vexing problem with no generally accepted solution to date. Since a racemic mixture of chiral nucleotides frustrates the extension and replication of RNA and DNA, understanding the origin of ...

Collective Attention in Virtual Teams: A Pathway for Mitigating Communication Delays

open access: yesPersonnel Psychology, Volume 79, Issue 2, Page 191-221, Summer 2026.
ABSTRACT Virtual work has become a defining feature of modern organizations, intensifying the need for strategies that support virtual team performance. Communication delays—prolonged intervals between sending and receiving messages—are one of the most persistent and consequential barriers to virtual team performance.
