While doping in East Germany has been intensely researched in the past decades, the state of West German athletics during this time has remained largely a mystery. In fact, doping was a common practice on both sides of the Iron Curtain. But how many athletes were involved? And who knew about these...

Biophysical studies in the 1950ies and 1960ies led to the realization that the water permeability of certain biological membranes must be due to the presence of water transporting proteins. This hypothesis was confirmed in 1991 and 1992 with the pioneering discovery of the first molecular membrane water channel, CHIP28, by Agre and coworkers. This integral membrane protein, which is abundant in the erythrocyte membrane and in many epithelial cells, is now called aquaporin-1 or AQP1. Thus the terms water channel or aquaporin are synonymous.
