On a map, submarine canyons seem identical to land canyons – so much so that researchers surmised they are shaped by the same physical laws. New research reveals distinct differences for the first time.
When significant oxygen entered the atmosphere, ancient life multiplied. But after a few hundred million years, Earth’s oxygen plummeted, resulting in a die-off likely greater than the extinction of the dinosaurs.
A geothermal energy project triggered a damaging earthquake in 2017 in South Korea. A new analysis suggests flaws in some of the most common ways of trying to minimize the risk of such quakes when harnessing Earth’s heat for energy.
Measurements of suspended sediment concentrations reveal a lot about the health of a waterway, but information has been difficult to obtain. A new approach uses a drone to take high-resolution photos to reveal turbidity.
