"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Researchers simulated temperature trends and tectonic plate movement to monitor their impact on mammals.

In a study published in Systematic Biology, researchers from Imperial College London, UCL, Dalhousie University and the United Nations Environment Program World Conservation Monitoring Center ...

How does the Earth generate its magnetic field? While the basic mechanisms seem to be understood, many details remain unresolved. A team of researchers has introduced a simulation method that promises ...

Imagine if scientists discovered a giant asteroid with a 72% chance of hitting the Earth in about 14 years — a space rock so big that it could not only take out a city but devastate a whole region.

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

Researchers have recreated the tumultuous beginnings of Earth, simulating what the planet was like just after its formation 4.5 billion years ago. The results, derived from a new computer model, ...

Stars like the Sun are remarkably constant. They vary in brightness by only 0.1% over years and decades, thanks to the fusion of hydrogen into helium that powers them. This process will keep the Sun ...

Chris Impey receives funding from the National Science Foundation and the Howard Hughes Medical Institute. Supernovae happen across the Milky Way only a few times a century, and these violent ...
