 | Geologists have confirmed the discovery of Earth's inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core. ...> Full Article |
 | Researchers have presented evidence that their theory about the core of the earth is correct. Among other applications, the findings may be of significance for our understanding of the cooling down of the earth, and of the stability of the earth's magnetic field. ...> Full Article |

 | Since we can't sample the deepest regions of the Earth, scientists watch the velocity of seismic waves as they travel through the planet to determine the composition and density of that material. Now a new study suggests that material in part of the lower mantle has unusual electronic characteristics that make sound propagate more slowly, suggesting that the material there is softer than previously thought. The results call into question the traditional techniques for understanding this region of the planet. The authors, including Alexander Goncharov from the Carnegie Institution's Geophysical Laboratory, present their results in the January 25, 2008, issue of Science. ...> Full Article |
Using a novel device that simulates earthquakes in a laboratory setting, a team of researchers have shown that seismic waves - the sounds radiated from earthquakes - can induce earthquake aftershocks, often long after a quake has subsided.
