Acquisition of an animal gene by microsporidian intracellular parasites

Acquisition of an animal gene by microsporidian intracellular parasites Correspondence Any scientific heroes? Hermann von Helmholtz, of course, and Richard Feynman. Both were physicists. Helmholtz was also both a physiologist and a psychophysicist, perhaps the best ever. Feynman was neither but his curiosity and his clarity are inspirational. His ability to observe was not bad either — remember the Challenger enquiry and the O ring? I cannot resist adding Julesz and Campbell, reluctant bedfellows though they may have made.
