Correction: Research featured in the item 鈥淧rof Snooty and his pals pick up the pounds鈥� (This Week, 8 July) was commissioned by the Management School of Imperial College, London, not by the Biotechnology and Biological Sciences Research Council as stated in the article.
Also, in 鈥淐omplex heart of a simple proton鈥� (1 July) it was incorrectly suggested that neutrinos carry charge. In fact, as stated elsewhere in the piece, neutrinos are chargeless relatives of electrons.
