A study suggests the weight of snow and ice atop the Sierra Nevada affects a California volcano's carbon dioxide emissions, one of the main signs of volcanic unrest.

On January 15, the volcano Hunga Tonga-Hunga Ha'apai devastated the nation of Tonga. The eruption triggered tsunamis as far afield as the Caribbean and generated atmospheric waves that travelled around the globe several times. Meanwhile, the volcano's plume shot gas and ash through the stratosphere into the lower mesosphere.

Researchers have proposed a method of assigned sex estimation that is 'population-inclusive,' or one that did not inherently rely on any estimation of ancestry (population affinity) by using 3D volume-rendered computed tomography (CT) scans of ancestry skulls to estimate assigned sex at birth.
