Feasibility Study for Dual Phase Free Breathing 3D bSSFP MRA With Preserved Eddy‐Current Tolerance With Adaptive k‐Space Lengths (PETAL) Acquisition

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2078-2091, April 2026.
ABSTRACT Purpose To demonstrate the feasibility of a novel dual‐phase self‐navigated, free‐breathing balanced steady‐state free‐precession whole‐heart MRA acquisition for aortic annulus size measurement using a Cartesian trajectory that mitigates eddy‐current artifacts by minimizing k‐space jumps between consecutive readouts with predictable scan times.

3D MR Thermometry Using Bi‐Directional Segmented EPI for Transcranial‐Focused Ultrasound

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2106-2116, April 2026.
ABSTRACT Purpose To evaluate the feasibility of replacing clinically utilized 2D thermometry with 3D segmented EPI‐based thermometry with equivalent accuracy, precision, and scan time. Methods A 3D segmented EPI (segEPI) trajectory was modified to allow readouts along both the forward and reverse direction for each phase encoding line, and the sequence

Reply to Comment by Hetényi and Cattin on: “Raising the Roof of the World: Intra‐Crustal Asian Mantle Supports the Himalayan‐Tibetan Orogen”

Tectonics, Volume 45, Issue 4, April 2026.
Abstract We welcome the critique of Hetényi and Cattin on Sternai et al. (2025, https://doi.org/10.1029/2025tc009057), as it brings to light evaluative issues that require clarification and offers an opportunity to articulate more clearly how our work advances understanding of Himalayan‐Tibetan geodynamics.

Cerebral and Peripheral Hemodynamics Across Wakefulness and NREM Sleep

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Wake/sleep‐related changes in cerebral hemodynamic oscillations are well established, but similar changes in peripheral hemodynamics remain largely understudied. Moreover, how the relationship between cerebral and peripheral hemodynamics varies across sleep–wake states is not well understood, despite evidence that these oscillations in the low‐

Differences in mycelial turnover and persistence of wood‐decay fungi at the microscale

New Phytologist, Volume 250, Issue 1, Page 577-590, April 2026.
Summary How long do fungal hyphae persist in the environment? And how does this differ between groups and species of fungi? Despite growing knowledge of fungal contributions to decomposition and soil carbon cycles, surprisingly little is known about the turnover of mycelia: What happens to fungal hyphae over time? And how this impacts different fungi's

Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone

Terra Nova, Volume 38, Issue 2, Page 106-115, April 2026.
ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

New Constraints on the Calabrian Arc (Central Mediterranean) Geodynamics: High‐Resolution Imaging of Lithospheric and Upper Mantle Discontinuities From P and S Receiver Functions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and upper mantle discontinuities across the Calabrian Arc and Southern Tyrrhenian basin.

Differential Craton Destruction Controlled by Fossil Structures in the Central North China Craton

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Craton evolution plays a fundamental role in stabilizing the continental lithosphere and the long‐term evolution of Earth's surface environment. The Shanxi Rift Zone (SRZ) within the North China Craton marks an ongoing craton destruction. Detailed lithospheric structure is essential to explain craton destruction.
