I am happy to share that our work on cyanophage infection in the Southern Ocean was published 🤩 https://t.co/FNtqXNAbA6

Here, we investigated the abundance of cyanophages and the extent to which they infect Synechococcus and Prochlorococcus, important primary producers, in the cold, low-light, iron-limited, sub-Anta...

Our results highlight that temperature-driven cellular mechanisms can drive the community dynamics and biogeography of marine viruses. This multidisciplinary study has been possible through great collaborations involving 3 continents: (5/6)

We used a mathematical model describing the temperature-driven virus-host dynamics to predict MpV-s distribution. We found that viral abilities to lyse and infect were good predictors of MpV-s presence and absence. (4/6)

By reconstructing virus phylogeny, we found that MpV-s were clustered into cryophile groups, growing mainly at low temperature below 10°C, or cryo-mesophile groups, growing from cold to more than 20°C. (3/6)

We focused on prasnoviurses infecting Micromonas (MpV), a picoeukaryote genus distributed from poles to tropics. We explored the distribution of isolated MpV-s in Tara datasets and highlighted that temperature is the main descriptor of their community composition. (2/6)

Delighted to share our new preprint on bioRxiv: https://t.co/Vg7bMpUN5X Where we integrated viral metagenomics and mathematical modelling to explore the temperature-driven biogeography of marine giant viruses - where do they live and why? (1/6)

Climate shapes the biogeography of microbial and viral communities in the ocean. Among abiotic factors, temperature is one of the main drivers of microbial community distribution. However, we lack...

For those working on viruses in aquatic environments, mark your calendars and consider submitting an abstract for Aquatic Virus Workshop 12 (AVW12) to be held in Banyuls-sur-Mer, May 5-9, 2025. Limited to 125 in total (register early). https://t.co/827ZJStNqA

It's publication day for "Asymptomatic" via @JHUPress. The book explores the paradox of asymptomatic transmission and rationale for proactive steps to confront future pandemics: https://t.co/OG2IBLnMV9

New paper in @nature shows #AI models collapse when trained on their own outputs—repeated AI-generated content leads to redundancy & gibberish. This mirrors our "Dilution of expertise" theory of cultural collapses: "too much imitation kills creativity." https://t.co/qqjY5ZMRKM

Excitement is building for the 12th iteration of the Aquatic Virus Workshop to be held at the fantastic Oceanologic Observatory in Banyuls-sur-Mer, France during 5-9 May 2025. We have a great lineup of speakers, and a nascent website: https://t.co/udBBHfGTUm

More soon... for now, delighted to share news of a @biorxivpreprint led by @mariandommi joint w/@D2mory & J. Harris focusing on the widely used one-step growth curve and how variability in cellular lysis can lead to biases in latent period estimates: https://t.co/IhnTEnusC9

https://t.co/ADZuW6Cw0K Thank you to @carlzimmer, who's written a very nice synthesis of people studying the dynamics of virus populations and cooperation and cheating of viruses - the sociovirology - including our work at @astar_research @idlabs_astar and with @meletios_tx on
quantamagazine.org
New research has uncovered a social world of viruses full of cheating, cooperation and other intrigues, suggesting that viruses make sense only as members of a community.

New paper from the MuLTEE in @NatureEcoEvo, this one on emergent eco-evolutionary dynamics. Led by @PineauRozenn and @SFI_elibby, we explore how the evolution of multicellularity creates opportunities for ecological niche expansion and coexistence. https://t.co/fH6wKtS24b
