By reviewing attendee lists of 10 MR (magnetic resonance) meetings over the last year, we estimate the climate footprint of conferences and explore possibilities to reduce it. This paper will facilitate discussions about possible actions the community may take.

Investigating NMR (nuclear magnetic resonance) phenomena at variable magnetic fields is useful and insightful for hyperpolarization and molecular dynamics in particular. To benefit from high-resolution at high magnetic fields, field-dependent investigations can be performed using a high-field NMR spectrometer, with a sample shuttle apparatus for field cycling. Here, we introduce a new design of a sample shuttle which is fast, reliable, and narrow. We show a series of applications involving small molecules and a protein in solution.

Protein structure and motion are key to its function. Using electron paramagnetic resonance (EPR) methods, it is possible to measure distances between magnetic markers like gadolinium ions grafted on proteins. Such measurements rely on the gadolinium phase memory time, determining how long the signal lasts. We studied how nearby atoms and environmental noise affect signal lifetimes using advanced EPR techniques. Our findings show how lifetimes can be extended to design better protein analysis.
