A New Way of Looking at the Earth's Interior

Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments now show that this view is too simplistic. Their results solve a key problem ...

Tackling Alarming Decline in Nature Requires 'Safety Net' of Multiple, Ambitious Goals

A 'safety net' made up of multiple ambitious and interlinked goals is needed to tackle nature's alarming decline, according to an international team ...

AI Detects Hidden Earthquakes

Tiny movements in Earth's outermost layer may provide a Rosetta Stone for deciphering the physics and warning signs of big quakes. New algorithms that work a little like human vision are now ...

Glimpse Deep Into Earth's Crust Finds Heat Source That May Stabilize Continents

Rocks from the Rio Grande continental rift have provided a rare snapshot of active geology deep inside Earth's crust, revealing new evidence for how continents remain stable over billions of ...

Driver of the Largest Mass Extinction in the History of the Earth Identified

252 million years ago, at the transition from the Permian to the Triassic epoch, most of the life forms existing on Earth became extinct. Using latest analytical methods and detailed model ...

Prebiotic Chemistry: In the Beginning, There Was Sugar

Organic molecules formed the basis for the evolution of life. But how could inorganic precursors have given rise to them? Chemists now reports a reaction pathway in which minerals catalyze the ...

Deep Sea Coral Time Machines Reveal Ancient CO2 Burps

The fossilized remains of ancient deep-sea corals may act as time machines providing new insights into the effect the ocean has on rising CO2 ...

Arctic Ocean Sediments Reveal Permafrost Thawing During Past Climate Warming

Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming events at the end of ...

A pioneering technique which captures precisely how mountains bend to the will of raindrops has helped solve a long-standing scientific ...

Supercomputing Study Breaks Ground for Tree Mapping, Carbon Research

A new method for mapping the location and size of trees growing outside of forests helped scientists discover billions of trees in arid and semi-arid regions and lays the groundwork for more accurate ...

Long-Term Data Show a Recent Acceleration in Chemical and Physical Changes in the Ocean

New research uses data from two sustained open-ocean hydrographic stations in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The ...

World's Greatest Mass Extinction Triggered Switch to Warm-Bloodedness

Mammals and birds today are warm-blooded, and this is often taken as the reason for their great ...

Unprecedented Energy Use Since 1950 Has Transformed Humanity's Geologic Footprint

A new study makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as ...

Stressed out Volcanoes More Likely to Collapse and Erupt

An international study has discovered how volcanoes experience stress. The study has implications for how the world might be better protected against future volcano ...

Deep Learning Artificial Intelligence Keeps an Eye on Volcano Movements

Radar satellites can collect massive amounts of remote sensing data that can detect ground movements -- surface deformations -- at volcanoes in near real time. These ground movements could signal ...

Climate Change Likely Drove Early Human Species to Extinction, Modeling Study Suggests

Of the six or more different species of early humans, all belonging to the genus Homo, only we Homo sapiens have managed to survive. Now, a study combining climate modeling and the fossil record in ...

Laser Technology Measures Biomass in World's Largest Trees

Laser technology has been used to measure the volume and biomass of giant Californian redwood trees for the first time, records a new ...

COVID-19 Lockdowns Averted Tens of Thousands of Premature Deaths Related to Air Pollution, Study Finds

Scientists have found that particulate matter concentrations in China dropped by an unprecedented 29.7 percent, and by 17.1 percent in parts of Europe, during lockdowns that took place between Feb. 1 ...

Thawing Permafrost Releases Organic Compounds Into the Air

When permafrost thaws due to global warming, not only the greenhouse gases known to all, but also organic compounds are released from the soil. They may have a significant impact on climate ...

Recent Atlantic Ocean Warming Unprecedented in Nearly 3,000 Years

Sediments from a lake in the Canadian High Arctic allow climate scientists to extend the record of Atlantic sea-surface temperature from about 100 to 2,900 years. It shows that the warmest interval ...

While the ongoing coronavirus pandemic continues to threaten millions of lives around the world, the first half of 2020 saw an unprecedented decline in carbon dioxide emissions -- larger than during ...

Scientists Shed New Light on Viruses' Role in Coral Bleaching
