This is my first visit to Small Things Considered and I find an article on retrons. It brings back good memories because I wrote an elective essay about msDNA/retrons in 1991 (as a third-year undergraduate student) due to its highly unusual structure, and possibly the first instance of retrotransposition in prokaryotes. Back then, its role(s) was unknown and, 20+ years down the track, is still pretty much the same except for the fascinating link between the retron and cholera pathogenesis. Thank you for the article and for maintaining such a great blogging site!
