Ancient ‘salt mountains’ in southern Australia once created refuges for early life

Salt is an essential nutrient for the human body. But hundreds of millions of years before the first humans, salt minerals once shaped entire landscapes. They even determined where early life on Earth could thrive.This […]

Plastic pollution could linger at ocean surfaces for over a century, new research finds

Phys.org

Scientists from the Department of Geography and Environmental Science at Queen Mary University of London have developed a simple model to show how buoyant plastic can settle through the water column and they predict it […]

Earlier volcano prediction at Mount Etna made possible by new earthquake pattern analysis

Phys.org

Located on the island of Sicily, in Italy, Mount Etna is one of the world’s most active volcanoes. Documentation of its many eruptions stretches back as far as 2,700 years ago, with the most recent […]

Hidden giant granite discovered beneath West Antarctic Ice Sheet

Phys.org

Pink granite boulders scattered across the dark volcanic peaks of the Hudson Mountains in West Antarctica, have revealed the presence of a vast buried granite body—almost 100 km across and 7 km thick, about half […]

Antarctic ice reveals two volcanoes erupting simultaneously may have caused 15th-century cooling

Phys.org

Nearly 600 years ago, a massive volcanic eruption sent clouds of sulfurous gas and ash high into the atmosphere. The blast known as the 1458/59 CE event was so huge that it triggered decades of […]

Retreating glaciers may send fewer nutrients to the ocean, study finds

Phys.org

The cloudy, sediment-laden meltwater from glaciers is a key source of nutrients for ocean life, but a new study suggests that as climate change causes many glaciers to shrink and retreat, their meltwater may become […]

While searching for the world’s oldest ice, scientists find sediment sneaking under the Antarctic ice sheet

Phys.org

For decades, researchers seeking to understand global climate change have analyzed ice cores drilled deep within the Antarctic ice sheet. This ice traps chemicals and bubbles of ancient air that tell the story of how […]

Geophysical-machine learning tool developed for continuous subsurface geomaterials characterization

Phys.org

Thailand’s northern regions, characterized by complex geology and active fault systems, experience frequent landslides that threaten both lives and critical infrastructure. In 2022, a slope failure occurred along Highway No. 1088 in Chiang Mai Province, […]

Increasing heat is super-charging Arctic climate and weather extremes

Phys.org

By evaluating historical climate records, observational and projection data, an international team of researchers found a “pushing and triggering” mechanism that has driven the Arctic climate system to a new state, which will likely see […]

Seismic anisotropy offers insight into viscous BLOBs at base of Earth’s mantle

Phys.org

In some parts of Earth’s interior, seismic waves travel at different speeds depending on the direction in which they are moving through the layers of rock in Earth’s interior. This property is known as seismic […]

Africa’s air links are poor: Can the G20 push for more direct flights to improve tourism and trade?

In Africa, less than one in five continental airline routes are direct. Air connections are decided by factors like trade levels, diplomatic relations, and whether there’s enough demand to make a route financially worthwhile. Because [...]

The economics of attention dominate modern-day active trading

In 2021, the stock market valuation of GameStop skyrocketed thanks to a social media frenzy. It heralded the rise of the so-called “meme” stock, but also a rise in a particular kind of trading, one [...]
