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 ...

Exposed rocks point to water on ancient Mars

A new discovery of hydrothermally altered carbonate-bearing rocks on Mars points toward habitable environments deep in the martian crust, a Planetary Science Institute researcher said.

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 ...

Evaluating the seismic risk of mineral carbon sequestration

Geologic carbon sequestration, in which carbon is captured and stored underground, has been proposed as one way to mitigate the climatic effects of carbon dioxide emissions. One method of geologic carbon sequestration is ...
