Viral Dark Matter: Illuminating Protein Function, Ecology, and Biotechnological Promises Viruses are the most abundant biological entities on Earth and play central roles in shaping microbiomes and influencing ecosystem functions. Yet, most viral genes remain uncharacterized, comprising w...

Viral "dark matter" dominates the virosphere. In this review by me & @karthik-a.bsky.social, we synthesize what's known, highlight major gaps, and outline paths forward for illuminating viral protein functions in diverse ecosystems.

Evolutionary age correlates with range size across plants and animals - Nature Communications Why are some species widespread while others are found only in small, isolated areas? This study shows that species with narrow ranges, and thus higher extinction risk, are often island-restricted, poor dispersers, and have evolved relatively recently.

Chimeric infective particles expand species boundaries in phage-inducible chromosomal island mobilization Capsid-forming PICIs (cf-PICIs) produce their own capsids and exploit phage tails from unrelated species to transfer their DNA across bacterial hosts. This tail piracy enables broad dissemination and ...

Thrilled to share our two latest papers with the @tcostalab.bsky.social

Excited to share my final work from the @soreklab.bsky.social!

We mined phage dark matter using structural features shared by anti-defense proteins (viral tools that help phages bypass bacterial immunity) to guide discovery.

Found 3 new families targeting immune signaling!
