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 ...
Researchers study 'smart' rocks use for detecting bridge damage
(Phys.org) —It's hard to gauge how structurally sound a bridge is when its foundation is buried in a riverbed deep below the water's surface. New "smart" rocks that are being developed by researchers at ...
New study ignites debate over Indonesia's mud volcano
Scientists on Sunday sparked a fresh debate over what triggered Indonesia's Lusi mud volcano, still spewing truckloads of slime more than seven years after it leapt catastrophically into life.
NASA's next Mars rover will advance hunt for past life
The next robotic rover to explore Mars in 2020 should scour the surface of the red planet more closely than ever for signs of past life, a NASA science team said Tuesday.
Curiosity Mars rover nears turning point
(Phys.org) —NASA's Mars Science Laboratory mission is approaching its biggest turning point since landing its rover, Curiosity, inside Mars' Gale Crater last summer.
Water-rock reaction may provide enough hydrogen 'food' to sustain life in ocean's crust or on Mars
A chemical reaction between iron-containing minerals and water may produce enough hydrogen "food" to sustain microbial communities living in pores and cracks within the enormous volume of rock below the ocean ...
Moons of Jupiter and Saturn could have been seeded with life
Life on Earth or Mars could have been brought to the moons of Jupiter or Saturn on rocks blasted off those planets, researchers say.
Curiosity rover team selects second drilling target on Mars
(Phys.org) —The team operating NASA's Curiosity Mars rover has selected a second target rock for drilling and sampling. The rover will set course to the drilling location in coming days.
Coral reefs 'ruled by earthquakes and volcanoes'
(Phys.org) —Titanic forces in the Earth's crust explain why the abundance and richness of corals varies dramatically across the vast expanse of the Indian and Pacific Oceans, a world-first study from the ...
Lunar impacts created seas of molten rock, research shows
Early in the Moon's history an ocean of molten rock covered its entire surface. As that lunar magma ocean cooled over millions of years, it differentiated to form the Moon's crust and mantle. But according ...
Study opens possibility of more dynamic biological oxygen cycle on early Earth than previously supposed
A research team of biogeochemists at the University of California, Riverside has provided a new view on the relationship between the earliest accumulation of oxygen in the atmosphere, arguably the most important ...
A creature from an alkaline spring could improve biofuel processing
(Phys.org) —The only truly practical biofuels will be those made from abundant feedstocks like switchgrass, wheat straw, and other woody plants, whose cell walls consist of lignocellulose. After pretreatment ...
Acid raid, ozone depletion contributed to ancient extinction
Rain as acidic as undiluted lemon juice may have played a part in killing off plants and organisms around the world during the most severe mass extinction in Earth's history.
