  We investigate interaction effects in transport phenomena in bilayer graphene
(BLG). For the minimal conductivity in pristine BLG, we find that the
conductivity assumes a constant value in the limit $T\to 0$, with the first
correction being $\propto \sqrt{T}$. This has to be contrasted from the
standard $1/T^2$ in Fermi liquids (neglecting additional logarithms and above
all disorder). We furthermore study the Coulomb drag resistivity between two
BLGs in the whole range from deep within the Fermi liquid regime all the way to
the charge neutrality (CN) point. We find that in the Fermi liquid regime drag
behaves very similarly to drag in a standard two-dimensional electron gas. In
contrast to monolayer graphene, we find no saturation of drag as a function of
the distance $d$ for realistic parameters. In the vicinity of CN, we find an
interesting interplay between interaction effects and disorder, like in the
case of monolayer graphene. Here the drag resistivity strongly depends upon the
ratio of the corresponding scattering times.
