Smallpox was eradicated relatively quickly, but other diseases have proved harder to eliminate. The reasons are a mix of biology and psychology.
Some viruses can replicate without infecting any one cell with all their genes.
New work raises the estimated diversity of viruses in the seas more than twelvefold and lays the groundwork for a better understanding of their impact on global nutrient cycles.
Researchers are beginning to understand the ways in which viruses strategically manipulate and cooperate with one another.
Jennifer Doudna, one of CRISPR’s primary innovators, stays optimistic about how the gene-editing tool will continue to empower basic biological understanding.
A newly discovered mechanism may enable viruses to shuttle genes between bacteria 1,000 times as often as was thought — making them a major force in those cells’ evolution.
Disease-causing viruses and message-carrying vesicles sit at the ends of a spectrum of membranous particles that cells release.
A newfound pair of giant viruses have massive genomes and the most complete resources for building proteins ever seen in the viral world. They have refreshed the debate about the origins of these cellular parasites.
If you didn’t get a flu shot, you are endangering more than just your own health. Calculations of herd immunity against common diseases don’t make exceptions.
