Magma can speed to the surface, powering volcanoes

Fast ascent of molten rock could help scientists predict eruptions.

Climate

Wetter permafrost clings to carbon better

In 12-year lab study, moist soil samples released less greenhouse gas as they warmed.

Environment

Atomic ant sand

Robb Hermes asked for sand ants to get samples of Trinitite, a material created in the test blasts of the first atomic bomb.

Millions of years ago, frozen ice sheet in East Antarctica melted

Warming may have caused ice sheet collapse and huge increase in sea level.

Earth

Huge quakes may foretell smaller, human-caused ones

Distant powerful temblors triggered ominous activity at wastewater injection sites.

Earth

Taking Antarctica’s temperature

Frozen continent may not be immune to global warming.

Earth

Every six years, Earth spins slightly faster and then slower

Changes in day length linked to workings of Earth's core.

Earth

Faults can reseal months after quakes

Measurements in southern China find quick healing of fractured rock.

Chemistry

High methane in drinking water near fracking sites

Well construction and geology may both play a role in pollution.
