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.
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.
Mathematical insights into how RNA helps viruses pull together their protein shells could guide future studies of viral behavior and function.
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.
Without viruses, we might never have evolved.
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.
Scientists are having a difficult time finding a treatment for the Zika virus in part because so few drugs are safe for pregnant women. But one antibiotic has shown promise.
Researchers are racing to understand how the Zika virus causes birth defects. Their first results have revealed tantalizing clues about how the virus interferes with the developing brain — and how it might be stopped.
