Summary: Monitoring plastic ingestion by marine wildlife is crucial for understanding the extent of plastic pollution and its impact on species and ecosystems. Current detection methods are slow and invasive, limiting the number of animals that can be screened. This study explores the use of MRI as a rapid and non-invasive method to detect plastic ingestion. The results show that MRI and NMR can directly or indirectly detect plastic in the digestive system of animals, with distinctive NMR signal characteristics for each type of plastic. While commercial MRI technology is not suitable for field use, existing single-sided MRI research systems could be adapted for monitoring wildlife outside the laboratory.

Summary: The physics of interacting nuclear spins in solids is well understood through the concept of nuclear spin temperature. By using adiabatic demagnetization, the nuclear spin system can be cooled, as demonstrated in a nominally undoped GaAs/(Al,Ga)As quantum well where selective cooling of As-75 spins was achieved. This study opens up new possibilities for exploring spin-spin interactions and exotic spin-ordered phases at unprecedented submicroKelvin temperatures in low-dimensional semiconductors.

Summary: The authors demonstrate a non-adaptive algorithm to increase the sensing range while approaching the best sensitivity, outperforming the standard measurement concept in both sensitivity and range. They thoroughly explore this algorithm by simulation and discuss the T-2 scaling in the coherent regime, contrasting it with the T-1/2 of the standard measurement. This algorithm can be applied to any modulo-limited sensor.

Summary: Research shows that both tapentadol and oxycodone can modulate the glutamatergic system at the supraspinal level in humans, leading to decreased glutamate/creatine levels in the brain regions studied.

Summary: Magnetic resonance elastography (MRE) is the most accurate noninvasive technique for diagnosing liver fibrosis. Recent studies have suggested that measuring splenic stiffness is useful in cases of portal hypertension. This study aims to establish normative data for MRE-assessed spleen stiffness in young adults.

Summary: This study proposes a method for detecting molecular vibrations in the mid-infrared range at room temperature. By assembling molecules into a plasmonic nanocavity resonant at both mid-infrared and visible wavelengths, and optically pumping them below the electronic absorption band, successful conversion of mid-infrared light and observation of enhanced visible luminescence were achieved.

Summary: Cardiac Magnetic Resonance Fingerprinting (cMRF) has shown to be a robust and accurate technique for T-1 and T-2 mapping. This study compared cMRF with a shorter acquisition window and low-rank reconstruction to routine cardiac mapping techniques. The proposed cMRF demonstrated higher accuracy and a wider range in phantom studies. In healthy volunteers and patients, cMRF showed significant differences in myocardial T-1 and T-2 compared to routine mapping. However, cMRF had lower precision but higher spatial resolution when compared to routine techniques.

Summary: In this article, a low-cost low-field nuclear magnetic resonance (NMR) cryoporometry system was developed to accurately measure the nanopore size of porous materials. The experimental results show that the proposed system has the ability to precisely control the temperature of samples and provide consistent measurements with known pore size distribution.

Summary: This study explores the application of eggshell membranes in polymer electrolyte fuel cells, aiming to develop cheaper and more eco-friendly options. The findings demonstrate that by using eggshell membranes as proton-conductive material, electricity can be generated, leading to cost reduction and further improvement of fuel cells.

Summary: This study investigated the variation of multiparametric MRI measurements throughout the day. The results showed that multiparametric MRI is stable over the day, although the coefficients of variation were higher for sodium MRI. These findings are important for the research and clinical significance of using multiparametric MRI to assess pathological and physiological changes in the kidneys.

Summary: This research demonstrates the possibility of surpassing the physical limits of spin polarization and achieving higher saturation limits in spin cooling using heat-bath algorithmic cooling schemes. Experimental evidence of the saturation of the HBAC limit has been observed, exceeding any available polarization in diamond nitrogen vacancy centers.

Summary: Utilizing quantum correlations of quantum targets allows for sensing schemes without classical counterparts, even when the second-order classical correlation of a quantum target is concealed by classical noise, higher-order quantum correlations can distinguish the quantum target from the noise, proposing a noise-free sensing scheme. This finding suggests that exploring quantumness of sensors and targets can realize the full potential of quantum sensing, offering new opportunities such as sensitivity beyond classical approaches and non-classical correlations in quantum many-body physics.

Summary: This study compared the acquisition time and image quality of CS and PI in oral T2-weighted imaging. The results showed that CSPI-T2WI had a shorter acquisition time and higher fat/muscle contrast ratio compared to PI-T2WI, with no significant differences in overall image quality, artifacts, and visualization of anatomical structures.
