Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract High‐altitude optical meteors initiating above 150 km are exceedingly rare, with confirmed observations largely confined to the Leonids. Using the Meteor and ionospheric Irregularity Observation System, we recorded a bright 43‐Cassiopeiids fireball with heterogeneous material. It initiated luminously at an exceptional altitude of 157.8 ± $\pm $

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.Abstract Quantifying decadal‐scale erosion rates in tectonically active regions is essential for assessing landscape hazards and constraining sediment budgets. A key question in Earth surface processes is how contemporary erosion measurements influenced by recent climatic extremes relate to long‐term geological rates.

Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging
Journal of Magnetic Resonance Imaging, Volume 63, Issue 4, Page 917-937, April 2026.ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...
