‘Broadband’ Networks of Viruses May Help Bacteria Evolve Faster

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.

Cells Talk in a Language That Looks Like Viruses

Disease-causing viruses and message-carrying vesicles sit at the ends of a spectrum of membranous particles that cells release.

New Giant Viruses Further Blur the Definition of Life

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 Unforgiving Math That Stops Epidemics

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.

Viruses Would Rather Jump to New Hosts Than Evolve With Them

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.

The Illuminating Geometry of Viruses

Mathematical insights into how RNA helps viruses pull together their protein shells could guide future studies of viral behavior and function.

Evolution Runs Faster on Short Timescales

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.

Viruses Find a New Way to Hijack Cells

A virus that causes crippling birth defects has been shown to do something else: It changes thousands of messages coming from DNA that control normal cellular activities.
