What to know about Buried in dark waters, viruses reshape one of Earth's largest carbon systems

Researchers from the University of North Carolina at Charlotte have discovered that viruses actively infect chemoautotrophic microbes in dark aquatic environments. This process influences the global carbon cycle by regulating microbial populations and accelerating the recycling of carbon.

What happened

Buried in dark waters, viruses reshape one of Earth's largest carbon systems Stephanie Baum Scientific Editor Robert Egan Associate Editor Viruses play a far more active role in Earth's carbon cycle than previously understood, according to new research that…

Why it matters

The findings are published in the journal Nature Communications.

Common ground

Viruses at work in the dark Aquatic environments absorb roughly 2.5 gigatons of atmospheric carbon each year, forming a critical buffer against climate change.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
