Better model of water under extreme conditions could aid understanding of...

Deep inside the Earth exist pockets of water, but the liquid there isn't like the water on the surface. When exposed to unimaginably high temperatures...

Site of the next major earthquake on the San Andreas Fault?

Many researchers hypothesize that the southern tip of the 1300-km-long San Andreas fault zone (SAFZ) could be the nucleation site of the next major...

Novel method for investigating pore geometry in rocks

Whether or not we realize it, mathematics permeates our lives in countless ways. Sometimes, the role of mathematics is difficult to grasp, but other...

Research led by Kuhan Chandru and Jim Cleaves from the Earth-Life Science Institute at Tokyo Institute of Technology, Japan, has shown that reactions of...

New insight into Earth’s crust, mantle and outer core interactions

A new study by the University of Liverpool, in collaboration with the Universities of Lancaster and Oslo, sheds light on a longstanding question that...

Thank the moon for Earth’s lengthening day

For anyone who has ever wished there were more hours in the day, geoscientists have some good news: Days on Earth are getting longer. A...

Land rising above the sea 2.4 billion years ago changed planet...

Chemical signatures in shale, the Earth's most common sedimentary rock, point to a rapid rise of land above the ocean 2.4 billion years ago...

Earth’s magnetic field is not about to reverse

A study of the most recent near-reversals of the Earth's magnetic field by an international team of researchers, including the University of Liverpool, has...

Was the Earth ever frozen solid?

The movie The Day After Tomorrow depicts a catastrophic climate shift to global cooling, which is referred to as the new ice age. In...

Why parts of Earth have barely changed in 3 billion years

There is a mystery in Earth's ancient past, and the clues lie in the desert rocks of Australia and other ancient places. The last century...

Ultrahigh-pressure laser experiments shed light on super-Earth cores

Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth. Scientists have identified more than 2,000 of these...

Meteorite diamonds tell of a lost planet

Using transmission electron microscopy, EPFL scientists have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows...

Water appeared while Earth was still growing

Up until about ten years ago, scientists thought they had a pretty good picture of how the moon and Earth came to co-exist. Then...

Brewing up Earth’s earliest life

Around 4 billion years ago, Earth was an inhospitable place, devoid of oxygen, bursting with volcanic eruptions, and bombarded by asteroids, with no signs...

Understanding the Earth under Hawaii

In the 1960s, some 50 years after German researcher Alfred Wegener proposed his continental drift hypothesis, the theory of plate tectonics gave scientists a...

Argonne’s powerful X-rays key to confirming water source deep below Earth’s...

A study published in Science last week relies on extremely bright X-ray beams from the U.S. Department of Energy's (DOE) Advanced Photon Source (APS)...

Diamonds from the deep: Study suggests water may exist in Earth’s...

Water on Earth runs deep - very deep. The oceans have been measured to a maximum depth of 7 miles, though water is known...

Unique diamond impurities indicate water deep in Earth’s mantle

A UNLV scientist has discovered the first direct evidence that fluid water pockets may exist as far as 500 miles deep into the Earth’s...

Do you know where your xenon is?

The paradox of the missing xenon might sound like the title of the latest airport thriller, but it's actually a problem that's stumped geophysicists...

New data helps explain recent fluctuations in Earth’s magnetic field
