Earth science: Deadly combination
New evidence suggests that seismic waves from the Chicxulub meteorite impact doubled the eruption rate of lavas on the opposite side of the planet — a combination that led to the mass extinction at the end of the Cretaceous period.

Plate tectonics on the Earth triggered by plume-induced subduction initiation
Scientific theories of how subduction and plate tectonics began on Earth—and what the tectonic structure of Earth was before this—remain enigmatic and contentious1. Understanding viable scenarios for the onset of subduction and plate tectonics2, 3 is…

North Pacific deglacial hypoxic events linked to abrupt ocean warming
Marine sediments from the North Pacific document two episodes of expansion and strengthening of the subsurface oxygen minimum zone (OMZ) accompanied by seafloor hypoxia during the last deglacial transition1, 2, 3, 4. The mechanisms driving this…

The effects of life history and sexual selection on male and female plumage colouration
Classical sexual selection theory1, 2, 3, 4 provides a well-supported conceptual framework for understanding the evolution and signalling function of male ornaments. It predicts that males obtain greater fitness benefits than females through multiple…
Global climate agreement: After the talks
