Thank you for your interest in writing a guest article for Capsid & Tail!

New update! Thanks to our super engaged community of phage enthusiasts (all of you!) we are outgrowing our old ways of getting each Capsid & Tail feature ready the week or two before it comes out. So we're updating how we handle guest blog submissions!

We will now be accepting guest blog submissions on a quarterly basis; so keep an eye on four deadlines throughout the year if you're thinking of contributing!

Submissions will be published on an approximately first-come, first-served basis, depending on any editing / back-and-forth that may be required.

Thanks to Stephanie Lynch for her help in rethinking our system!

Although a large proportion of our audience is generally knowledgeable about phages, we aim to keep Capsid & Tail light and readable, and NOT highly technical. We want this to be easy reading—an interesting tidbit that doesn't require a lot of concentration (each article should take ~5-10 minutes to read). Feel free to use active voice and first person pronouns, and to be conversational!
