Fish welfare in a changing world: New developments and current challenges

Journal of Fish Biology, EarlyView.
Abstract The welfare of non‐human animals is central to ethical discussions on animal use, with increasing attention to fish welfare across research, aquaria, aquaculture, and fisheries. This paper reviews current theoretical approaches to animal welfare and recent advances in defining and assessing fish welfare since the seminal paper by Huntingford ...

Multiwavelength Study on Solar and Interplanetary Origins of the Strongest Geomagnetic Storm of Solar Cycle 23

, 2011
We study the solar sources of an intense geomagnetic storm of solar cycle 23 that occurred on 20 November 2003, based on ground- and space-based multiwavelength observations.

Influence of a geomagnetic storm on geo-resistivity observation and analysis of its physical mechanism

地震科学进展
Based on observation data from five survey points within the Jilin regional geo-resistivity observation network, this study systematically analyzes the influence of a geomagnetic storm event with Kp index of 9 that occurred in May 2024 on ground ...

Probabilistic prediction of geomagnetic storms and the Kp index

Journal of Space Weather and Space Climate, 2020
Geomagnetic activity is often described using summary indices to summarize the likelihood of space weather impacts, as well as when parameterizing space weather models. The geomagnetic index K p in particular, is widely used for these purposes. Current

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

First Results of a New Inversion Tool for Thermospheric Neutral Mass Density Computations During Severe Geomagnetic Storms

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Impact of Solar Irradiance on Low-Earth-Orbit Satellite Orbital Decay During Geomagnetic Storm

Aerospace
In recent years, with the rapid expansion of low-Earth-orbit (LEO) satellite constellations, the orbital decay of LEO satellites caused by atmospheric heating from solar irradiance and geomagnetic activity has become increasingly prominent.

Status and Prospect of Secondary Battery Technologies in Space Applications: Challenges and the Future

Batteries &Supercaps, Volume 9, Issue 5, May 2026.
Lithium‐ion batteries used in space applications are exposed to extreme conditions, including radiation, vacuum, wide temperature fluctuations, and long storage times, all of which accelerate degradation. This review article summarizes the main degradation mechanisms affecting battery performance in space environments, including capacity fade ...
