Tiny 3-D images shed light on origin of Earth's core

(PhysOrg.com) -- A new method of capturing detailed, three-dimensional images of minute samples of material under extreme pressures is shedding light on the evolution of the Earth's interior. Early results suggest that the ...

How the air we breathe was created by Earth's tectonic plates

How is it that Earth developed an atmosphere that made the development of life possible? A study published in the journal Nature Geoscience links the origins of Earth's nitrogen-rich atmosphere to the same tectonic forces ...

Study suggests space dust carries water and organic compounds

Researchers from the University of Hawaii-Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST), Lawrence Livermore National Laboratory, Lawrence Berkeley National Laboratory, and University of California – ...

Ancient forests stabilized Earth's CO2 and climate

UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low for plants to ...

Why is the Earth's F/Cl ratio not chondritic?

Primitive chondrites, un-molten stony meteorites, are believed to be the building blocks of the Earth. Because terrestrial planets have experienced chemical differentiation in the core, mantle, and hydrosphere, the elemental ...

Sex or food? Decision-making in single-cell organisms

Unicellular diatoms are able to adapt their behavior to different external stimuli based on an evaluation of their own needs. This was discovered by scientists of the Friedrich Schiller University and the Max Planck Institute ...
