Query: Primary operations in differential cohomology   We characterize primary operations in differential cohomology via stacks, and
illustrate by differentially refining Steenrod squares and Steenrod powers
explicitly. This requires a delicate interplay between integral, rational, and
mod p cohomology, as well as cohomology with U(1) coefficients and differential
forms. Along the way we develop computational techniques in differential
cohomology, including a K\"unneth decomposition, that should also be useful in
their own right, and point to applications to higher geometry and mathematical
physics.
