S eeing is believing. This old saying sums up one of the main goals in biology and biophysics: to watch and ultimately understand the molecular processes that sustain life. Thanks to advances in both experimentation and simulation, we are rapidly gaining a molecular-level understanding of key biomolecular processes. Nevertheless, experiments remain largely limited to the identification and char...
