Recent developments are reviewed in the scaling theory of phase-coherentconduction through a disordered wire. The Dorokhov-Mello-Pereyra-Kumar equationfor the distribution of transmission eigenvalues has been solved exactly, inthe absence of time-reversal symmetry. Comparison with the previous predictionof random-matrix theory shows that this prediction was highly accurate --- butnot exact: The repulsion of the smallest eigenvalues was overestimated by afactor of two. This factor of two resolves several disturbing discrepanciesbetween random-matrix theory and microscopic calculations, notably in themagnitude of the universal conductance fluctuations in the metallic regime, andin the width of the log-normal conductance distribution in the insulatingregime. ***To be published as a "Brief Review" in Modern Physics Letters B.****Comment: 9 pages, LATEX, INLO-PUB-940309
