I recently attended the ESF Research Conference "Antiviral RNAi" June 11-15th in Pultusk, Poland. Ben Berkhout, one of Retrovirology’s Associate editors, was a co-organizer of the meeting. Below is a group picture taken at the Polonia Castle in Pultusk.  Several very interesting talks were presented at this conference, and a meeting report is slated to be published in EMBO Reports soon;  so keep your eyes out for that writeup.   Coincidentally, a few days ago, I wrote a short Opinion piece for BMC Biology on RNAi and mammalian viruses.  https://www.biomedcentral.com/1741-7007/10/58  It makes for brief reading; so take a look if you are interested in this topic.
