Abstract
We outline our recent results on bicovariant differential calculi on co-quasitriangular Hopf algebras, in particular that if ${\mathfrak g}_\Gamma$ is a quantum tangent space (quantum Lie algebra) for a CQT Hopf algebra $A$, then the space $k\oplus {\mathfrak g}_\Gamma$ is a braided Lie algebra in the category of $A$-comodules. An important consequence of this is that the universal enveloping algebra $U({\mathfrak g}_\Gamma)$ is a bialgebra in the category of $A$-comodules.
