Unraveling the symmetry of Al<sub>5</sub>C<sub>3</sub>N. [PDF]

open access: yesActa Crystallogr B Struct Sci Cryst Eng Mater
From experimental and theoretical techniques employed in this thorough reexamination of the structure of Al5C3N, the crystal structure is better described in centrosymmetric space group P63/mmc (No. 194) rather than in the previously reported noncentrosymmetric space group P63mc (No. 186).High‐temperature ceramic compound Al5C3N belongs to the scarcely

Association Between Geomagnetic Activity and Unsuccessful Out-of-Hospital Cardiac Arrest. [PDF]

open access: yesGeohealth
Abstract Out‐of‐hospital cardiac arrests (OHCAs) represent a significant global health challenge, with a survival rate <10%. Recent research has demonstrated that geomagnetic activity (GMA) can disrupt the circadian rhythm. Therefore, GMA may affect patient outcomes after an OHCA event wherein resuscitation is attempted.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

From distant shores to an emerging island: the role of surface and subsurface transport in modeling seed dispersal

open access: yesEcography, EarlyView.
Long‐distance seed dispersal by ocean currents plays a critical role in structuring coastal plant communities. As direct observations of this phenomenon are infeasible, numerical modeling is a valuable tool. Here, we use Lagrangian particle tracking to examine the colonization of the newly forming island Norderoogsand (German Bight, Wadden Sea) by five

Reflections of Swedish Fathers in Late Adulthood on Their Past and Present Parental Role in Relation to the Mother

open access: yesScandinavian Journal of Psychology, EarlyView.
ABSTRACT With a contextual and developmental perspective, this study aimed to examine Swedish late‐adult fathers' reflections on their past and present parental role in relation to the mother and to see how these reflections incorporate changes in gender and parenthood during recent decades in Sweden.

Bounce Resonance Between ULF Waves and Electrons in the Dayside Outer Magnetosphere

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Resonant interactions between ultra‐low‐frequency (ULF) waves and particles are critical for energy transfer in the Earth's magnetosphere, and have been extensively investigated in the inner magnetosphere. However, resonant processes between ULF waves and electrons in the dayside outer magnetosphere remain largely unexplored.

Revealing the Formation of the <20 MeV Inner Proton Radiation Belt at L ∼ 2 During the 10–11 May 2024 Superstorm

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract A new proton radiation belt was identified during the geomagnetic superstorm of 10–11 May 2024. To investigate its origin, we use an MHD‐test particle simulation to model solar energetic proton (SEP) trapping and the evolution of the initial trapped proton population during the storm.

Evolution of NWC Transmitter Wave Power Distribution From the Topside Ionosphere Into the Inner Magnetosphere

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Ground‐based very low frequency transmitters emit signals that primarily propagate within the Earth–ionosphere waveguide, and some of their energy can propagate into the magnetosphere. Ionospheric observations from the DEMETER satellite reveal a distinct concentric rings pattern of the wave power distribution of the North West Cape transmitter

First Observation of Sawtooth‐Like Undulations in Afternoon Detached Auroral Arcs Modulated by Surface Waves at the Plasmaspheric Plume Boundary

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract The afternoon detached auroral arc is an important phenomenon in the subauroral region, reflecting coupling processes between the Earth's magnetosphere and ionosphere. Previous studies have not identified fine‐scale structures in such arcs, leaving the dynamics underlying their formation poorly understood.
