Should the government prioritize funding for long-term scientific research into virus evolution?
Researchers at Portland State University have secured a $1 million grant from the National Science Foundation to study how viruses evolve. The three-year project will focus on the unique behavior of cruciviruses, which can bridge the divide between RNA and DNA genomes.
Why it matters
Understanding how these viruses swap genetic material offers insight into how viruses emerge and could eventually improve how we develop tools for gene therapy and vaccine delivery. The work builds on the lab's decade-long investigation into these rare viral structures.
The National Science Foundation is providing $1 million to support a three-year research project at Portland State University. The funding will fuel an investigation into the evolutionary history of cruciviruses, a project that remains limited by the currently unknown identity of their host microbes.
The players
Portland State University
The public university in downtown Portland where the eXtreme Virus Lab operates.
National Science Foundation
The federal agency that supports fundamental research and education in all non-medical fields of science and engineering.
The details
The university's eXtreme Virus Lab will use machine learning to build evolutionary trees from viral genetic sequences. Researchers aim to map how horizontal gene transfer allows cruciviruses to enclose both RNA and DNA genomes, a capability not seen in other known viruses. The team plans to sample environments, including sites in Antarctica, to identify the eukaryotic microbes that serve as hosts.

Beyond the Bridges
This project directly extends the 2012 discovery of cruciviruses by Stedman's lab by applying modern machine learning to solve the mystery of their evolutionary origins. It marks a significant shift from mere identification to modeling the complex recombination patterns that define these rare viruses.
While the work happens in the lab, PSU plans to launch virtual programs to share their findings on virus evolution with rural communities. These outreach efforts aim to bring the science of viral emergence out of the university and into classrooms across the state.
The takeaway
The research into cruciviruses could eventually refine how scientists design gene therapies and vaccines. Keep an eye on future updates from the eXtreme Virus Lab as they begin their three-year timeline of environmental sampling and computational modeling.
