A review of B B-bar mixing results at the end of July 1999 is presented. Emphasis is put on recent measurements of Delta-Md and Delta-Ms. For Delta-Md, the new world average is Delta-Md = 0.473 +- 0.016 ps-1. For Delta-Ms, the new world average 95% CL limit is 12.4 ps-1, with a sensitivity of 14.2 ps-1. Other related results are covered very briefly.
We present the first results on tau physics using polarized beams. These include measurements of the $τ$ Michel parameters $ξ$ and $ξδ$ and the $τ$ neutrino helicity $h_ν$. The measurements were performed using the SLD detector at the Stanford Linear Collider (SLC). (Invited talk at the 1995 International Europhysics Conference on High Energy Physics, Brussels, Belgium, July 27 - August 2, 1995.)
