31P‐MRS of the Human Heart at 7 T With an Integrated Whole‐Body 31P Radiofrequency Transmit Coil

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
We demonstrate the use of an integrated whole‐body phosphorus‐31 (31P) radiofrequency transmit coil for 31P‐MR spectroscopic imaging of the human heart at 7 T. Intersession measurement repeatability of the mid‐septal myocardial phosphocreatine (PCr) over adenosine triphosphate (ATP) concentration ratio in normal volunteers was 17.7%.

Longitudinal 3D‐DCE MRI Assessment of Placental Perfusion Under Reduced Uterine Perfusion Pressure in Pregnant Rats

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
This first application of longitudinal 3D‐DCE MRI in the RUPP model demonstrated acute perfusion deficits after RUPP that resolved rapidly with advancing gestation, consistent with the adaptive placental responses to reduced uterine blood flow. ABSTRACT Placental insufficiency is a major cause of preeclampsia and fetal growth restriction.

Multimodal MRI Reveals Cerebral and Vascular Amyloid‐Driven Myeloarchitectural Disorganization in a Mouse Model of Alzheimer's Disease

NMR in Biomedicine, Volume 39, Issue 4, April 2026.
This study investigates the effect of cerebral and vascular (beta‐amyloid) Aβ on regional myeloarchitecture and lipid composition in a murine model of Alzheimer's disease (AD). The study highlights the feasibility of quantitative MRI and chemical exchange saturation transfer (CEST) imaging to identify multiple biophysical mechanisms involved in ...

Bio‐Inspired Swarm Robotics Design for Mine Automation

Natural Sciences, Volume 6, Issue 2, April 2026.
Ants demonstrate tandem running for cooperative haulage, and honeybees use memory‐based routes between hive and flowers. These behaviours inspire autonomous haulage robots in open‐pit mines to achieve efficient scan‐plan‐retrieve ore transport, replacing small haulage robots with large mining trucks.

At the core of the interaction: Probing charged side chains in flexible protein regions with simultaneous nuclear magnetic resonance experiments

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Charged amino acid side chains are crucial mediators of biomolecular recognition, but their characterization by nuclear magnetic resonance (NMR) is often hindered by conformational and solvent exchange, particularly for arginine guanidinium groups.
