“Phages” include viruses of eubacteria and archaea. At least 5568 phages have been
examined in the electron microscope since the introduction of negative staining in 1959 …

One of the most prominent features of archaea is the extraordinary diversity of their DNA
viruses. Many archaeal viruses differ substantially in morphology from bacterial and …

Prokaryote viruses include 14 officially accepted families and at least five other potential
families awaiting classification. Approximately 5,500 prokaryote viruses have been …

The study of viruses has traditionally focused on their roles as infectious agents and as tools
for understanding cell biology. Viruses are now finding a new expanded role as …

When viruses were discovered, they were accepted as missing links between the inert world
and living organisms. However, this idea was soon abandoned as information about their …

Materials scientists increasingly draw inspiration from the study of how biological systems
fabricate materials under mild synthetic conditions by using self‐assembled macromolecular …

Recent discoveries of new large DNA viruses reveal high diversity in their morphologies,
genetic repertoires, and replication strategies. Here, we report the novel features of …

Viruses are the most abundant living entities and probably had a major role in the evolution
of life, but are still defined using negative criteria. Here, we propose to divide biological …

Viruses infecting cells from the three domains of life, Archaea, Bacteria and Eukarya, share
homologous features, suggesting that viruses originated very early in the evolution of life …

Prokaryotes, bacteria and archaea, are the most abundant cellular organisms among those
sharing the planet Earth with human beings (among others). However, numerous ecological …
