Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Differentiating Plumes and Local Torus Segments of Enceladus

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Self‐Healing Materials from Electronically Integrated Microscopic Robots

Advanced Intelligent Systems, Volume 8, Issue 1, January 2026.
Submillimeter robots can use electronically controlled electrodeposition to assemble into a material structure. The resulting aggregate possesses ultralow density, high strength‐to‐weight ratio, and can heal from damage. Further afield, these results clear a path to materials that organize or adapt by directing matter and information at the microscale.

Magnetic Resonance Neurography of the Brachial Plexus at 1.5 T: Diagnostic Reliability and Time Efficiency of Bilateral Ultra‐Fast 3D STIR vs. Unilateral 2D Dixon

International Journal of Imaging Systems and Technology, Volume 36, Issue 1, January 2026.
ABSTRACT Recent technological advancements may now allow shorter reliable magnetic resonance neurography (MRN) scans of the brachial plexus (BP) even at 1.5 T. The objective of this study was to compare ultra‐fast bilateral coronal 3D T2w TSE STIR (3D‐IR) with unilateral sagittal 2D T2w TSE Dixon (2D‐DX) in terms of image quality, diagnostic ...

The far-infrared/submillimeter properties of galaxies located behind the Bullet cluster* [PDF]

, 2010
The Herschel Lensing Survey (HLS) takes advantage of gravitational lensing by massive galaxy clusters to sample a population of high-redshift galaxies which are too faint to be detected above the confusion limit of current far-infrared/submillimeter ...
