Spider silk formation involves tightly regulated protein assembly, influenced by pH and the presence of ions. Here, single-molecule mass photometry reveals that mini-spidroin interactions are influenced by millimolar concentrations of sodium and potassium, which may control the formation of spidroin clusters.

Quantifying the degree of correlation required to drive a Mott insulator transition is a crucial aspect in understanding and manipulating correlated electrons. Here, the authors introduce a thallium-based cuprate system and use resonant inelastic X-ray scattering, combined with Hubbard-Heisenberg modeling, to establish a universal relation between electron interactions and magnon dispersion, suggesting optimal superconductivity at intermediate correlation strength.

Precise thin film growth is pivotal for applications in electronics and coatings, yet kinetics-dominated film morphology remains challenging to control.
