Earth's deep mantle flows dynamically
As ancient ocean floors plunge over 1,000 km into the Earth's deep interior, they cause hot rock in the lower mantle to flow much more dynamically than previously thought, finds a new UCL-led study.

Changes in ocean 'conveyor belt' foretold abrupt climate changes by four centuries
In the Atlantic Ocean, a giant 'conveyor belt' carries warm waters from the tropics into the North Atlantic, where they cool and sink and then return southwards in the deep ocean. This circulation pattern is an important ...
Fatal horizon, driven by acidification, closes in on marine organisms in Southern Ocean
Marine microorganisms in the Southern Ocean may find themselves in a deadly vise grip by century's end as ocean acidification creates a shallower horizon for life, new University of Colorado Boulder research finds.
The solid Earth breathes
The solid Earth breathes as volcanoes "exhale" gases like carbon dioxide (CO2)—which are essential in regulating global climate—while carbon ultimately from CO2 returns into the deep Earth when oceanic tectonic plates ...
Cool Earth theory sheds more light on diamonds
A QUT geologist has published a new theory on the thermal evolution of Earth billions of years ago that explains why diamonds have formed as precious gemstones rather than just lumps of common graphite.
What can machine learning reveal about the solid Earth?
Scientists seeking to understand Earth's inner clockwork have deployed armies of sensors listening for signs of slips, rumbles, exhales and other disturbances emanating from the planet's deepest faults to its tallest volcanoes. ...
Earth is a less volatile version of the Sun, study finds
ANU scientists have found that Earth is made of the same elements as the Sun but has less of the volatile elements such as hydrogen, helium, oxygen and nitrogen.
US-Russian crew blasts off to International Space Station
A Russian-American crew of three blasted off to the International Space Station early Friday, making a second attempt to reach the outpost after October's aborted launch.
Strong planetary magnetic fields like Earth's may protect oceans from stellar storms
A study by scientists at ANU on the magnetic fields of planets has found that most planets discovered in other solar systems are unlikely to be as hospitable to life as Earth.
Researchers unravel mysteries of Earth's inner core
Researchers from The Australian National University (ANU) are unlocking some of the secrets of the Earth's inner core by adapting and further developing a technique used in hospitals around the world.
