How much magma is hiding beneath our feet?
Molten rock (or magma) has a strong influence on our planet and its inhabitants, causing destructive volcanic eruptions and generating some of the giant mineral deposits. Our understanding of these phenomena ...
Rainwater discovered at new depths
University of Southampton researchers have found that rainwater can penetrate below the Earth's fractured upper crust, which could have major implications for our understanding of earthquakes and the generation ...
Tough, light and strong: Lessons from nature could lead to the creation of new materials
In a sweeping review of the field of bio-inspired engineering and biomimicry in the Feb. 15 issue of the journal Science, two engineers at the University of California, San Diego, identify three characteristics of bio ...
Fossilized conduits suggest water flowed beneath Martian Surface
(Phys.org)—Networks of narrow ridges found in impact craters on Mars appear to be the fossilized remnants of underground cracks through which water once flowed, according to a new analysis by researchers ...
Surveying Earth's interior with atomic clocks
Ultraprecise portable atomic clocks are on the verge of a breakthrough. An international team lead by scientists from the University of Zurich shows that it may be possible to use the latest generation of ...
Researchers say atomic clocks now good enough to measure Earth's geoid
Out of thin Martian air
A wet Mars is just a memory, but where did the water go?
Australia's Antarctic claim 'at risk'
Australia holds the largest claim to Antarctica but risks losing it in any race to unlock the frozen continent's potentially vast mineral and energy resources, an influential thinktank said Monday.
NASA wants mission to bring Martian rocks to Earth
(AP) -- For the past decade, NASA's Mars exploration strategy was to follow the water.
Rich Ore Deposits Linked to Ancient Atmosphere
(PhysOrg.com) -- Much of our planet's mineral wealth was deposited billions of years ago when Earth's chemical cycles were different from today's. Using geochemical clues from rocks nearly 3 billion years old, a group of ...
Stalagmites in Northeast Brazilian Caves Confirm 9,000-Year Model of Diminishing Rainfall
(PhysOrg.com) -- Until recently, researchers studying climate history in Brazil’s dry Nordeste region expected it to have wet and dry periods similar to the rest of South America. But over the past 9,000 ...
Challenges and ethics of harvesting the mineral wealth of the deep sea
One of the great challenges facing all societies is to achieve a balance between economic growth and environmental integrity. It's not easy and it requires buy-in from all sectors of society.
Mineralization of sand particles boosts microbial water filtration
Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper published ahead of print in Applied and Environmental Mi ...
Amplifier invention probes far beneath the surface
An exploration "amplifier" under development in WA could allow scientists to see deeper into the Earth and search further below the surface of Mars.
