1. New property found in ancient mineral lodestone
   12-17-2007 · EurekAlert!
   Using the latest nanofabrication methods, a team of Rice University physicists has discovered a surprising new electronic property in one of the earliest-known and most-studied magnetic minerals on Earth -- lodestone. Also known as magnetite, lodestone was used to make compass needles as early as 900 years ago. In new research in Nature Materials, the researchers describe how super-cooled magnetite reverted from an insulator to a conductor when the voltage was altered in their experiment.

10. Life-giving rocks from a depth of 250 km
    09-26-2007 · EurekAlert!
    If our planet did not have the ability to store oxygen in the deep reaches of its mantle there would probably be no life on its surface. This is the conclusion reached by scientists at the University of Bonn who have subjected the mineral majorite to close laboratory examination. Majorite performs an important function as an oxygen reservoir. Near the Earth's surface the mineral breaks down, releasing oxygen, which then binds with hydrogen from the Earth's interior to form water.
