Cryo-electron microscopy (cryo-EM) has become a powerful tool for determining the structures of proteins, viruses and molecular complexes at near-atomic resolution. However, achievable resolution is fundamentally limited by the Nyquist sampling frequency, which is determined by detector pixel si...
