Sustaining Science Infrastructure Is Difficult; Is Commercialization the Answer? The USA National Phenology Network's Experience

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Biological and physical science infrastructure programs play a critical role in supporting scientific discovery. Even with their foundational roles in the process of science, frequently, support for these programs is threatened, reduced, or eliminated, placing critical data and information at risk of interruption or loss.

Astrophysical Accretion as an Analogue Gravity Phenomena [PDF]

, 2006
In recent years, strong analogies have been established between the physics of acoustic perturbations in an inhomogeneous dynamical fluid system, and some kinematic features of space-time in general relativity.

Why Idealized Models Are More Important Than Ever in Earth System Science

AGU Advances, Volume 6, Issue 4, August 2025.
Abstract Simulating the Earth system is crucial for studying Earth's climate and how it changes. Modeling approaches that simplify the Earth system while retaining key characteristics are important tools to advance understanding. The simplicity and flexibility of idealized models enables imaginative science and makes them powerful educational tools ...

Spatial Distribution and Plasmaspheric Ducting of Auroral Kilometric Radiation Revealed by Wind, Polar, and Arase

AGU Advances, Volume 6, Issue 4, August 2025.
Abstract Auroral Kilometric Radiation (AKR), the dominant radio emission from Earth, has been extensively studied, though previous analyses were constrained by limited spacecraft coverage. This study utilizes long‐term observations from Polar, Wind, and Arase spacecraft to generate comprehensive global AKR occurrence rate maps, revealing a high ...

Unveiling the Global Characteristics of Turbulence in the Venusian Space Environment

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Turbulence plays a crucial role in energy transfer from large to small scales in solar wind‐Venus interaction. Observations have identified magnetic field fluctuations and turbulence in the Venusian space environment. However, due to limited observations and simulation resolutions, neither the global characteristics nor the driving mechanisms ...

Influence of Low Magnetic Fields on Hydrogen Evolution Reaction Performance of NiCoP Electrocatalysts

ChemPhysChem, Volume 26, Issue 14, July 18, 2025.
Herein, electrocatalytic activity enhancement is reported of NiCoP nanorods by applying an external magnetic field. The NiCoP nanorods exhibit an overpotential of 100 mV at 10 mA cm−2 without magnetic field. However, under low magnetic field of 2000 G, the overpotential reduces to 62 mV at 10 mA cm−2 in 0.5 M H2SO4, demonstrating that external magnetic

Slow Solar Wind: Origin in an Independent Small‐Scale Solar Dynamo

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Separation of the solar wind (SW) into three flow types (coronal mass ejections (CMEs), high speed streams (HSSs), and slow solar wind (SSW)) reveals an inverse relationship between the percentage of time Earth spends in SSW during a year and its annually averaged magnetic field strength (B).

Upstream IMF Influence on Closed Magnetic Field Orientation on Mars

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Closed magnetic fields play an important role in plasma transport and atmospheric escape from the Martian dayside ionosphere. Leveraging in‐situ magnetic field data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, we conduct a statistical analysis of closed magnetic field behavior under varying upstream conditions. Our findings
