Ancient Impact Melt Near the Lunar South Pole: Distribution, Provenance, and Sampling Strategy

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Due to a lack of pre‐Nectarian samples associated with specific impacts in the Apollo suite, the early Solar System's impact chronology is poorly constrained. We investigate where Artemis and other south polar lunar missions could sample impactites to determine the ages of pre‐Nectarian craters, focusing on the ancient craters Haworth ...

Calibration Method of Empirical Atmospheric Density Based on Physics‐Informed Neural Networks

open access: yesSpace Weather, Volume 24, Issue 10, October 2026.
Abstract Thermospheric density is a critical parameter for low Earth orbit satellite applications, including orbit prediction, collision risk assessment, and atmospheric drag analysis. However, empirical atmospheric density models exhibit significant uncertainties under disturbed space weather conditions, while purely data‐driven approaches may not ...

Israel's Post‐War Healthcare Obligations

open access: yesBioethics, Volume 40, Issue 8, Page 828-832, October 2026.
ABSTRACT Since the beginning of the Israel–Hamas war in 2023, the healthcare infrastructure within Gaza has been dismantled. While international humanitarian law mandates distinction between lawful targets (combatants and military objectives) and non‐lawful targets (civilians and civilian objects), and acknowledging the inherent complexities of ...

Common inputs to motor units are modulated by force profile and muscle length

open access: yesExperimental Physiology, Volume 111, Issue 10, Page 4876-4893, 1 October 2026.
Abstract Groups of motor units receive common synaptic inputs from specialized networks of premotor neurons to produce movement. Here, we test whether common inputs received by motor units in the first dorsal interosseous are fixed or task‐dependent during submaximal isometric contractions.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 14, 23 September 2026.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.
