Visualization of small vibrations inside an MRI scanner using video motion amplification

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Diffusion‐weighted magnetic resonance imaging (DW‐MRI) acquisition requires the application of strong magnetic field gradients, which can induce mechanical vibrations in tissues or phantoms, potentially leading to signal loss or degradation.

Noninvasive 11.7‐T Magnetic Resonance Spectroscopy and Imaging Reveals Retinal Metabolic Alterations Induced by Blue Light Exposure

NMR in Biomedicine, Volume 39, Issue 3, March 2026.
Retinal metabolic changes were analyzed using proton magnetic resonance spectroscopy (1H‐MRS), marking an initial application of this non‐invasive method on living eyes. Key metabolites were identified within the retinal region of adult rats. The observed changes following intense blue light exposure were predominantly attributable to the retina, as it

Frozen Soil Hydrological Processes and Their Effects: A Review and Synthesis

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Frozen soils, including seasonally frozen ground and permafrost, are rapidly changing under a warming climate, with cascading effects on water, energy, and carbon cycles. We synthesize recent advances in the physics, observation, and modeling of frozen‐soil hydrology, emphasizing freeze–thaw dynamics, infiltration regimes and preferential flow,

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Self‐ and Electrodic‐Potential Response to Hydrological and Biogeochemical Processes in the Soil‐Tree Continuum

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Forest sustainability is regulated by the interplay between water and biochemical fluxes within the soil–tree continuum. However, capturing the daily to seasonal interplay of these ecohydrological and biological processes remains a major challenge.
