Apparently, all early-type galaxies are forming stars after all - not many, but some : they're red but not quite dead. This had been suspected rather strongly before but here the confirmation looks quite decisive. Caveats are that there's a whopping great extrapolation in the paper and they don't comment on gas content or environment, but it's still a nice piece of work.
