The Influence of Topography and Crustal Magnetic Anomalies on the Distribution of Water Ice in the Lunar South Pole Region

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Lunar magnetic anomalies are abundant near the south pole, where several moderate‐strength anomalies spatially overlap permanently shadowed regions (PSRs). This environment provides a unique setting to assess how crustal magnetic fields and topography regulate plasma–surface interactions and, in turn, the stability and distribution of surface ...

A Different Position: Protest Medicine and the Limits of Professional Neutrality

open access: yesSociology of Health &Illness, Volume 48, Issue 6, July 2026.
ABSTRACT Protests are a persistent feature of contemporary urban life, often producing mass injuries through police repression. Yet the role of medical care in these contexts—especially when provided by informal collectives—remains understudied. Drawing on 21 in‐depth interviews with members of volunteer medical brigades during Chile's 2019–2020 ...

Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

open access: yesJournal of Forensic Sciences, Volume 71, Issue 4, Page 1607-1620, July 2026.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Complementarity in alliances: How strategic compatibility and hierarchy promote efficient cooperation in international security

open access: yesAmerican Journal of Political Science, Volume 70, Issue 3, Page 925-945, July 2026.
Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

Infants and Mobiles: Developing an Understanding of Cause and Effect

open access: yesDevelopmental Science, Volume 29, Issue 4, July 2026.
ABSTRACT In the mobile conjugate reinforcement paradigm, an infant's leg is connected to a mobile via a string, allowing the infant to move the mobile via moving their leg. Over a few minutes, infants exhibit an increase in the frequency of movement of the connected leg.

Static recrystallization of shocked calcite in Ries impact breccias

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 7, Page 1456-1473, July 2026.
Abstract Calcite is prone to chemical and microstructural modifications, especially after having been strained at high stresses and strain rates, as during hypervelocity impact events. These modifications include precipitation from pore fluid as well as replacement of strained volumes by recrystallization. In calcite aggregates of a metagranite breccia
