I am happy to share that our data descriptor on the Hawaiʻi Diel Sampling is now published! 🌊🦠https://www.nature.com/articles/s41597-025-06166-3
Every 1.5 hours for 48 hours, we collected ocean microbes from within and adjacent to Kāneʻohe Bay, Oʻahu, Hawaiʻi and produced a multi-omics dataset.

Thrilled to share our new study! We show that mirusviruses include lineages packed with spliceosomal introns and likely replicating in the nucleus of unicellular eukaryotes—a sharp contrast to most large and giant eukaryotic viruses that replicate in the cytoplasm.

Widespread and intron-rich mirusviruses are predicted to reproduce in nuclei of unicellular eukaryotes - Nature Microbiology
Environmental metagenomic explorations show that Mirusviricota lineages lack essential replication and transcription genes and contain spliceosomal introns, suggesting nuclear reproduction.

The new Wiley journal review system is an absolute nightmare. Editorial assistants have been replaced by a clunky, AI-enabled website that makes it harder to find and invite reviewers. Associate editor workloads have increased. I'm not convinced the invitations to reviewers are even going through.

Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change.
Ie: it's not us (Samtools team)! Be warned
