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.
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.
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.
The discovery that viruses move between species unexpectedly often is rewriting ideas about their evolutionary history — and may have troubling implications for the threat from emerging diseases.
