Abstract

Adaptive memory in insect immunity has been controversial. In this issue, Andino and co-workers propose that acquisition of viral sequences in the host genome gives rise to anti-sense, anti-viral piRNAs. Such sequences can be regarded as both a genomic archive of past infections and as an armour of potential heritable memory.
