Huge and widespread volcanic eruptions triggered the end-Triassic extinction
More than 200 million years ago, a massive extinction decimated 76 percent of marine and terrestrial species, marking the end of the Triassic period and the onset of the Jurassic. This devastating event cleared ...
Curiosity rover finds conditions once suited for ancient life on Mars
(Phys.org) —An analysis of a rock sample collected by NASA's Curiosity rover shows ancient Mars could have supported living microbes.
Computed tomography provides real-time 3-D pictures showing how oil and water flow in porous rock
For the first time, experiments using computed tomography have allowed scientists to observe in 3D the flow of oil and water in real rock on an unprecedented scale. The new approach trailed and the information ...
Hoodoos—key to earthquakes?
In the absence of long-term instrumental data, fragile rock formations, called hoodoos, may be key to understanding seismic hazard risk. In this study, researchers consider two hoodoos in Red Rock Canyon region to put limits ...
Nullarbor region once full of fast-flowing rivers
(Phys.org)—University of Adelaide geologists have shed new light on the origin of Australia's largest delta, the Ceduna Delta, and the river systems which drained the continent millions of years before ...
ChemCam follows the 'Yellowknife Road' to Martian wet area
(Phys.org)—Researchers from Los Alamos National Laboratory and the French Space Agency have tracked a trail of minerals that point to the prior presence of water at the Curiosity rover site on Mars.
Can we accurately model fluid flow in shale?
(Phys.org)—Given that over 20 trillion cubic meters of natural gas, a third of the United States' total reserves, are thought to be trapped in shale, and given the rush to exploit shale oil and gas resources ...
Earliest evidence of life found: 3.49 billion years ago
New test adds to scientists' understanding of Earth's history, resources
(Phys.org)—A new study co-authored by a University of Florida researcher provides the first direct chronological test of sequence stratigraphy, a powerful tool for exploring Earth's natural resources.
A 3.45-billion-year-old diet
Researchers are providing new information about the 'diet' of microorganisms on the early Earth. By studying 3.45-billion-year-old rocks, the team uncovered clues about ancient microbial metabolism.
Shale energy production spike revolutionising energy sector
A spike in shale oil and gas production is revolutionising the energy sector and risks weighing on prices of conventional crude, according to industry experts.
After long-ago mass extinction, global warming hindered species' recovery
Researchers have discovered why plants and animals had a hard time recovering from the largest mass extinction in Earth's history 250 million years ago.
Gale before Curiosity: What we knew and what the rover may reveal
The first comprehensive analysis of what we knew about the Gale crater on Mars before the recent landing of space rover Curiosity has been published by the International Journal of Astrobiology (IJA).
Interglacial on snowball Earth
Researchers from Royal Holloway, University of London have discovered that ice retreated completely through the glaciations.
