Just one piece out in German this month, a slightly delayed account of the discovery of taste receptors for salt, which essentially completes the set. While not all details have been worked out, there are now at least strong candidate receptors and cells for each of the five elementary taste sensations. Amazingly, most of the key discoveries were made by the same team (collaboration of Charles Zuker and Nicholas Ryba), who I think should be up for a Nobel prize within the next few years.
