Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Observational Signatures of Simulated Reconnection Events in the Solar Chromosphere and Transition Region

, 2009
We present the results of numerical simulations of wave-induced magnetic reconnection in a model of the solar atmosphere. In the magnetic field geometry we study in this article, the waves, driven by a monochromatic piston and a driver taken from Hinode ...

Cassini in situ observations of long duration magnetic reconnection in Saturn’s magnetotail [PDF]

, 2015
Magnetic reconnection is a fundamental process in solar system and astrophysical plasmas, through which stored magnetic energy associated with current sheets is converted into thermal, kinetic and wave energy1, 2, 3, 4.

Kinetic Scale Magnetic Reconnection with a Turbulent Forcing: Particle-in-cell Simulations

The Astrophysical Journal, 2023
Turbulent magnetic reconnection has been observed by spacecraft to occur commonly in terrestrial magnetosphere and the solar wind, providing a new scenario of kinetic scale magnetic reconnection.

Observations of Turbulent Magnetic Reconnection within a Solar Current Sheet [PDF]

The Astrophysical Journal, 2018
Abstract Magnetic reconnection is a fundamental physical process in various astrophysical, space, and laboratory environments. Many pieces of evidence for magnetic reconnection have been uncovered. However, its specific processes that could be fragmented and turbulent have been short of direct observational evidence.

Universal Time Influence on Stormtime Magnetosphere Ionosphere Coupling

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract The offset between Earth's magnetic and rotational axes introduces a diurnal dependence in the high‐latitude EUV exposure of the northern hemisphere (NH) and southern hemisphere (SH). This variation raises the question: Does the Universal Time (UT) of geomagnetic storm onset impact its geospace consequences?

The Role of Helicity in Magnetic Reconnection: 3D Numerical Simulations

, 1999
We demonstrate that conservation of global helicity plays only a minor role in determining the nature and consequences of magnetic reconnection in the solar atmosphere.

First-principles theory of the rate of magnetic reconnection in magnetospheric and solar plasmas

Communications Physics, 2022
Different models exist to characterize magnetic reconnection, a process that converts magnetic energy into plasma thermal and kinetic energy, but a quantitative theoretical predictive model of how rapidly it proceeds has been lacking.

Auroral Emissions on Ganymede: New Constraints on Their Electron Energy Dependence

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Auroral emissions on Ganymede provide critical insights into its magnetospheric dynamics and atmospheric composition. Using a physics‐based atmospheric model with recent atmospheric observations and laboratory measurements of electron‐impact cross‐sections, this study revisits and significantly refines the relationship between auroral emission
