1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria.

1/ How do animals develop immunity against a newly encountered transposable element from scratch? Our study reveals that the mobility of TEs is their Achilles heel, allowing hosts to develop a powerful small RNA-mediated silencing response.
