Minute Witnesses From Earth’s Primordial Sea

Earth scientists often face huge challenges when researching the earth’s history: many significant events occurred such a long time ago that there is little direct evidence available. Consequently, researchers often […]

A Carbon Cycle Flaw Can Plunge Earth Into An Ice Age

UC Riverside researchers have discovered a piece that was missing in previous descriptions of the way Earth recycles its carbon. As a result, they believe that global warming can overcorrect […]

Shocked Quartz At The Younger Dryas Onset Supports Cosmic Airbursts/Impacts

Shocked quartz grains are an accepted indicator of crater-forming cosmic impact events, which also typically produce amorphous silica along the fractures. Furthermore, previous research has shown that shocked quartz can […]

The Biology, Microclimate, and Geology of a Distinctive Ecosystem Within the Sandstone of Hyper-Arid Timna Valley, Israel

Microbial endolithic communities in the sandstone rocks of the southern Negev Desert, particularly in Timna Park, were initially discovered by Imre Friedmann and Roseli Ocampo-Friedmann in their pioneering study about […]
