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

In achiral PFAS with 2–3 CF₂ groups, long-lived ¹⁹F spin states (T_LLS) were measured and found to last about 3× longer than T₁ in a static 11.6 T field. These lifetimes are sensitive to macromolecular binding, making them useful for screening fluorinated drugs. T_LLS and T₁ are expected to increase at lower fields where ¹⁹F CSA effects are weaker.

Proteins structure and motion are key to their 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 lifetime using advanced EPR techniques. Our findings show how lifetime can be extended to design better protein analysis.
