In the first part of the seminar, I will review a novel and rapidly developing class of atomic clocks: optical lattice clocks, which have reached an accuracy of 10-17 -- 10-18. In the second part, I will provide an overview of atomic searches for new physics beyond the Standard Model. I will report on a refined analysis of experiments on parity violation in atoms. Our raised bound on the mass of Z', a hypothetical extra Z-boson, improves upon the Tevatron results and carves out a lower-energy part of the discovery reach of the Large Hadron Collider.
