  • Single-molecule Förster resonance energy transfer (smFRET) can be used to probe the structural dynamics underlying the functional complexity of G protein-coupled receptors (GPCRs), however, the approach is limited to specific timescales. Here, the authors use smFRET with anti-Brownian electrokinetic (ABEL) trapping to extend the observation time of untethered A2A adenosine receptors (A2AAR) embedded in lipid nanodiscs from milliseconds to seconds, characterizing conformational heterogeneity in both apo and ligand-bound A2AAR and updating previous estimates of dwell times for long-lived receptor states.

  • Interaction between Cooper pairs and other collective excitations may reveal important information about the pairing mechanism. Here, the authors observe a universal jump in the phase of the driven Higgs oscillations in cuprate thin films, indicating the presence of a coupled collective mode, as well as a nonvanishing Higgs-like response at high temperatures, suggesting a potential nonzero pairing amplitude above Tc.

  • A streak camera for characterizing the ultrashort X-ray pulses produced by a free-electron laser is reported. The scheme has a single-shot capability, a resolution of a few femtoseconds and is expected to become a useful tool for X-ray metrology, including experiments involving time-resolved spectroscopy and imaging.

  • Bacterial growth rate depends on the number of active ribosomes and translation elongation rate. Matamouros et al. show that Corynebacterium glutamicum, a gram-positive model species, uses a different strategy than Escherichia coli during slow growth by strongly reducing the translation elongation rate while keeping a high number of active ribosomes.

  • Numerous correlated materials exhibit an in-plane anisotropic ground state but their origin is unclear. Here the authors control the orientation of orbital domains in a manganite using the polarization of terahertz pulses, which can be explained by field-induced enhancement of the electron interactions.

  • Inertial dynamics are observed in a ferromagnet. Specifically, a nutation is seen on top of the usual spin precession that has a lifetime on the order of 10 picoseconds.
