A System for Retrofitting Conventional MRI Systems for Simultaneous Multinuclear MRI/MRS

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
We present a low‐cost system for retrofitting conventional narrow‐band MRI spectrometers with simultaneous multinuclear capability using heterodyne frequency translation. The system supports up to four nuclei and 16 receive channels, with reconfigurable transmit modes and inherent phase stability through a shared local oscillator architecture ...

Task‐Evoked Functional Activation and Coupling With CSF Flow Detected in the Human Brain With Ultrashort Echo Time fMRI at 7 T

NMR in Biomedicine, Volume 39, Issue 8, August 2026.
Ultrashort and zero echo time (UTE and ZTE) MRI techniques generate functional contrast through inflow effects, making them suitable for studying cerebral blood flow and cerebrospinal fluid (CSF) dynamics. In a 7‐T study of 13 participants performing a visual task, we demonstrate that UTE produced robust, reproducible activations with group‐level ...

Spatial Heterogeneity of Atlantic Water Upward Heat Flux in the Eurasian Basin Revealed by MOSAiC

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Atlantic Water (AW) is the main oceanic heat source in the Arctic and a key driver of sea ice retreat. Based on Multidisciplinary drifting Observatory for the Study of Arctic Climate microstructure data from the Eurasian Basin, we examined the spatial heterogeneity of AW upward heat flux.

Cryogenic Dielectric Metasurface‐Integrated Superconducting Nanowire Single‐Photon Detectors

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Superconducting nanowire single‐photon detectors (SNSPDs) are the leading technology for single‐photon detection because of their near‐unity system detection efficiency, ultrahigh timing precision, and very low dark counts. However, achieving these performance metrics with single element, small‐active‐area SNSPDs has been an outstanding challenge. Here,
