Excited to share our grad student Akash Arani’s (co-first author) recent paper in the ISME Journal! Along with collaborators at @ua.es, we show how episomal virus maintenance enables bacterial recovery and promotes virus–host coexistence in hypersaline environments. doi.org/10.1093/isme...

Episomal virus maintenance enables bacterial population recovery from infection and promotes virus–bacterial coexistence
Abstract. Viruses are ubiquitous in aquatic environments with total densities of virus-like particles often exceeding 107/ml in surface marine oligotrophic

Congratulations to @juliepourtois.bsky.social, a postdoc in our group, on her new paper now available as an In Press Preview on JCI! 🥳🥳🥳 Based on her PhD at Stanford, the study shows how new Pseudomonas infections drive Pf phage spread in CF airways. Read it here: insight.jci.org/articles/vie...

A new paper co-authored by Weitz Group member @mariandm.bsky.social on latent period heterogeneity is now on bioRxiv! It explores how variation in viral latency shapes virus-host dynamics and introduces a new framework for trait estimation. Check it out here: www.biorxiv.org/content/10.1...

Delighted to share news that Emma Wachter defended her honor's thesis on 'Assessing mechanisms of non-exponential decay in viral systems' in the Dept. of Biology at UMD as part of her work in @weitz-group.bsky.social. She is off to Dana Farber for a postbac. Congrats to Emma!

An engaging meetup on matters aquatic viral ecology related... in advance of the international Aquatic Virus Workshop in early May to take place in Banyuls-sur-Mer. Thanks to @beckettstephen.bsky.social, @juliepourtois.bsky.social + @tgoel.bsky.social + all participants for making it possible.

Had a great meeting talking science and discussing avenues for moving frontiers at the Maryland aquatic viral ecology meeting last week. Many thanks to co-organizers @juliepourtois.bsky.social and @tgoel.bsky.social, and to all who participated!

Bonus link for those interested, another way to look at this same issue is here: bsky.app/profile/leos... Reinforcing the key message - CDC's measles page should be updated to dispel the impression that the outbreak is always on the way out, when that's not the case.

Working with an interdisciplinary team, we have developed a website to communicate how the White House's proposed cuts to health research would cause losses of $16B and 68,500 jobs. Find out how your community may be impacted. Explore more at SCIMaP: scienceimpacts.org a 🧵

👋 Hello Bluesky! We’re the Weitz Group at the @univofmaryland.bsky.social, led by Prof. @joshuasweitz.bsky.social. We study how viruses shape the fate of cells, populations, and ecosystems—combining theory, data, and a dash of quantitative chaos. Please, follow us here. 🧪📈🦠 #WeitzGroup
