differential cohomology
The (generalised) homology of Thom spectra $M G$, such as MO and MU.
In the presence of a Thom isomorphism (e.g. for complex oriented cohomology of MU) this identifies with the homology of the classifying spaces $B G$, such as $B O$ and $B U$.
Feeding the homology of $M G$ into an Adams spectral sequence gives a way to compute its homotopy groups.
This is for instance a key ingredient in Quillen's theorem on MU giving the homotopy groups of $MU$.
For $E$ a complex oriented cohomology theory, there is an isomorphism of graded rings
where the $\{b_i \in E_\bullet(M U(1))\}$ are a dual basis to the basis $\{t^{i+1} \in E^\bullet(M U) \simeq t (\pi_\bullet E)[ [ t ] ]\}$ that is induced by the complex orientation.
