The discovery of giant viruses, with capsids as large as some bacteria, megabase-range
genomes and a variety of traits typically found only in cellular organisms, was one of the …

The opportunistic protist Acanthamoeba, which interacts with other microbes such as
bacteria, fungi, and viruses, shows significant similarity in cellular and functional aspects to …

DNA viruses have a major influence on the ecology and evolution of cellular organisms,,–,
but their overall diversity and evolutionary trajectories remain elusive. Here we carried out a …

Viruses, despite their great abundance and significance in biological systems, remain
largely mysterious. Indeed, the vast majority of the perhaps hundreds of millions of viral …

The ongoing COVID-19 pandemic has piqued public interest in the properties, evolution,
