＂Why do arginine and pyrimidines have to be considered together？＂ This was the question I asked when I was invited by Barbara Zimmermann to attend the 23rd Intemational Conference on Arginine and Pyrimidines （ICAP） three years ago. The meeting was held in the summer of 2012 at Bogota, Columbia, known as the ＂the Athens of South America＂. I am not alone in wanting to know more about the relationship between arginine and pyrimidines. Last summer, when ! was organising the next ICAP meeting at Oxford （Aughey et al., 2014）, one of my colleagues asked me, ＂Why such a weird name for a conference？＂ I am not sure if I had given her a satisfying answer and I was enthused to find out what the reasons may be.
