Examine evolution over the course of years or centuries, and you’ll find that it progresses much more quickly than it does over geologic time.
Researchers have used the gene-editing tool CRISPR to manipulate the way that DNA coils up inside the cell — another step in the quest to understand how the genome’s 3-D structure impacts its function.
Only a few genetic changes were enough to change an ordinary stomach bug into the bacteria responsible for the plague.
A new understanding of viral swarms is helping researchers predict how viruses will evolve and where disease is likely to spread.
Newly discovered specimens support a more ancient origin for viruses, perhaps all the way back to the origins of life.
A new theory suggests that cooperation between a host and its microbes may be a significant evolutionary force.
