Contrasting Genomic Responses of Hydrothermal Vent Animals and Their Symbionts to Population Decline After the Hunga Volcanic Eruption
Genetic bottlenecks are evolutionary events that reduce the effective size and diversity of natural populations, often limiting a population’s ability to adapt to environmental change.

Volcanic Emissions Of Reactive Sulfur Gases May Have Shaped Early Mars Climate, Making It More Hospitable To Life
While the early Mars climate remains an open question, a new study suggests its atmosphere may have been hospitable to life due to volcanic activity which emitted sulfur gases that […]

Hunga Volcano Eruption Cooled, Rather Than Warmed, Earth’s Southern Hemisphere
When Hunga Tonga–Hunga Haʻapai, an underwater volcano near Tonga in the South Pacific Ocean, erupted in 2022, scientists expected that it would spew enough water vapor into the stratosphere to […]
