Dissolved Organic Matter (DOM) Dynamics at the Sediment‐Water Interface in the North Sea: Implications for Global Benthic DOM Fluxes

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Sediment–water exchange of dissolved organic matter (DOM) represents a critical yet poorly constrained component of the marine carbon cycle. Here, we combine quantitative, molecular, and carbon isotope (δ13C and F14C) analyses to investigate the production, composition, and export of porewater DOM in the German Bight, North Sea, and evaluate ...

Iterative and Steady Black Auroral Stripes and Their Possible Causality in Plasma‐Sheet Electron Distributions: Implications From Low‐Altitude Reimei Observations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract Iterative black auroral stripes were identified in auroral images obtained by the low‐altitude microsatellite Reimei. These steady and narrow black stripes are a remarkable feature of diffuse auroras generated by energetic electrons precipitating at higher latitudes than pulsating auroras.

Linacs for Medical Isotope Production

Atom Indonesia, 2011
This paper reviews efforts on using high energy (25-30 MeV) and high power (10-20 kW) electron linacs and lower energy (7 MeV) proton linacs for medical radioisotope production.

On the Detection of Low‐Frequency Planetary Radio Emission With an Orbiting Interferometer

Radio Science, Volume 61, Issue 6, June 2026.
Abstract The magnetized planets of the outer Solar System produce kilometric radio emissions at very low frequencies (<1 ${< } 1\,$MHz). They reveal the planetary magnetic dynamics and their interaction with the solar wind. Those radio emissions can also serve as a proxy for interplanetary space weather monitoring.

Circularly Expanding Ring‐Shaped Pulsating Aurora Visualizing the Source of Plasma Waves in Space

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Pulsating aurorae are prominent auroral emissions in the polar regions, typically occurring in the morning hours during the recovery phase of auroral substorms. These aurorae usually consist of round‐shaped patches of emission, with luminosity that pulsates at intervals ranging from less than a second to several tens of seconds.

Ion Anisotropy in Earth's Magnetotail: Importance of High‐Energy Ions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 6, June 2026.
Abstract The reconfiguration of the magnetotail current sheet during substorms often includes the formation of a thin current sheet (TCS) with a strong magnetic field line tension force. This force cannot be balanced by isotropic plasma pressure gradients, and force balance in such a TCS requires ion anisotropy and/or agyrotropy of plasma pressure.
