Polydopamine‐Based Antioxidant Countermeasures Against Spaceflight‐Induced Neurodegeneration

Small Science, Volume 6, Issue 1, January 2026.
Polydopamine nanoparticles (PDNPs) protect neuron‐like cells from microgravity‐ and cosmic radiation‐induced oxidative stress. Through in‐flight and ground‐based experiments, it has been shown that PDNPs preserve neuronal and mitochondrial function, markedly mitigating transcriptional dysregulation caused by spaceflight.

Deep‐Ultraviolet (DUV) Raman and Fluorescence of Perchlorates and Chlorates: Implications for the Detection of Oxychlorines by the SHERLOC Instrument in Jezero Crater, Mars

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Oxychlorines (i.e., perchlorates (ClO4−) and chlorates (ClO3−)) have been detected by several landed missions on Mars at various locations. These missions have provided crucial information about the geographic distribution and abundances of oxychlorines on Mars but have not definitively identified the cation and anion type of in situ, solid ...

Enhanced Radiation Exposure of Airline Crew and Passengers During the May 2024 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Enhanced radiation at aviation altitudes is a concern for flight crew and passengers. During space weather events, solar flares and coronal mass ejection (CME) driven shocks are sources of energetic particles that can reach Earth's near‐space environment and interact with its magnetic field and atmosphere.

An Extended Amplitude Range Readout Circuit for Charged Particle Detection–BEAR 2

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Charge sensitive amplifiers (CSA) form the first stage of most detector readout circuits. The operating range of the readout circuits depends on the saturation limits of the Charge sensitive amplifiers, thereby limiting the range of the detector system as well. A number of methods have been introduced to extend the dynamic range of the readout

Imaging of Magma Intrusion Below La Palma During a Strong Effusive Eruption in 2021 Inferred From Repeated Seismic Tomography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The 2021 eruption of Cumbre Vieja on La Palma, Canary Islands, provided a unique opportunity to investigate the dynamics of magma migration and storage during a large effusive eruption. In this study, we employ repeated seismic tomography to image temporal changes in the subsurface structure beneath La Palma, using body‐wave travel times from ...
