Nowadays, we can see the position of atoms as if we had vision millions of times sharper than human eyes allow. This is the gift of structural biology – the science of determining the 3D structures of molecules and correlating them with function. Structural biology gives us something more powerful than human vision, as the wavelength of ‘visible’ light is too long to resolve the position of atoms.
