How seaweed became multicellular

A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or ‘seaweed,’ to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods…

Innovative antiviral defense with new CRISPR tool

The rise of RNA viruses like SARS-CoV-2 highlights the need for new ways to fight them. RNA-targeting tools like CRISPR/Cas13 are powerful but inefficient in the cytoplasm of cells, where many RNA viruses replicate. Scientists have devised a solution: …
