Dear WM, It is curious that the same tomographic features have been interpreted in completely different ways. Faster than average seismic wave-speeds in the TZ have been considered to indicate ancient subducted slabs (Piromallo & Morelli, 2003; Handy et al., 2010). The same features, on the other hand, have also been interpreted as a volatile-free mantle plume head trapped in the TZ (Lavecchia & Bell, 2012; Bell et al., 2013).– Michele Lustrino

Dear WM, Interesting article in the most recent Economist publicising a Nobel laureate’s jaundiced views on “luxury journals” (Science, Nature and Cell). Seems like the groundswell of discontent is growing.–Andy Moore
