Analysis of cancer metabolism by imaging hyperpolarized nuclei: prospects for translation to clinical research.
The known abnormalities in cancer metabolism, the value and limitations of current imaging methods for metabolism, and the principles of hyperpolarization are summarized.

A simple method was developed for evaluating the efficacy of face masks to reduce respiratory droplet emission during speaking and observed that some mask types approach the performance of standard surgical masks, while some mask alternatives, such as neck gaiters or bandanas, offer very little protection.
Generation of impossible cross-peaks between bulk water and biomolecules in solution NMR.
These results imply that peak intensities (critical for structural determinations) can be distorted in many gradient experiments, and show that magic-angle gradients provide substantial improvements with reduced gradient strengths.
MR imaging contrast enhancement based on intermolecular zero quantum coherences.
A new method for magnetic resonance imaging (MRI) based on the detection of relatively strong signal from intermolecular zero-quantum coherences (iZQCs) is reported. Such a signal would not be…

Coherent Control of Quantum Dynamics: The Dream Is Alive
Current experimental and theoretical progress toward the goal of controlling quantum dynamics is summarized and the introduction of engineering control concepts has put the required theoretical framework on a rigorous foundation.
Femtosecond Phase-Coherent Two-Dimensional Spectroscopy
Femtosecond phase-coherent two-dimensional spectroscopy has been experimentally demonstrated as the direct optical analog of 2D nuclear magnetic resonance and the desired nonlinear polarization was selected by phase cycling.
