Making ultra-fast electron measurements in multiple directions to reveal the secrets of the aurora

The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments ...

Q&A: Clarifying the megathrust earthquake mechanism

There is a 70-80% chance that the Nankai Trough Megathrust Earthquake will occur in the next 30 years. It is predicted to cause more extensive damage than the 2011 Great East Japan Earthquake and fatalities may exceed 320,000.

A 3D view into chaos: Researchers visualize temperature-driven turbulence in liquid metal for the first time

Experiments with liquid metals could not only lead to exciting insights into geophysical and astrophysical flow phenomena, such as atmospheric disturbances at the rim of the sun or the flow in the Earth's outer core, but ...

Emergency atmospheric geoengineering wouldn't save the oceans

Climate change is heating the oceans, altering currents and circulation patterns responsible for regulating climate on a global scale. If temperatures dropped, some of that damage could theoretically be undone.

Scientists set the stage for quantum chemistry in space on NASA's cold atom lab

For the first time in space, scientists have produced a mixture of two quantum gases made of two types of atoms. Accomplished with NASA's Cold Atom Laboratory aboard the International Space Station, the achievement marks ...

Supercomputer used to simulate winds that cause clear air turbulence

A research group from Nagoya University has accurately simulated air turbulence occurring on clear days around Tokyo using Japan's fastest supercomputer. They then compared their findings with flight data to create a more ...

Campi Flegrei volcano edges closer to possible eruption

The Campi Flegrei volcano in southern Italy has become weaker and more prone to rupturing, making an eruption more likely, according to a new study by researchers at UCL (University College London) and Italy's National Research ...

A pool at Yellowstone is a thumping thermometer

While the crowds swarm around Old Faithful to wait for its next eruption, a little pool just north of Yellowstone National Park's most famous geyser is quietly showing off its own unique activity, also at more-or-less regular ...

Mysteries of Earth: Researchers predict how fast ancient magma ocean solidified

Early in the formation of Earth, an ocean of magma covered the planet's surface and stretched thousands of miles deep into its core. The rate at which that "magma ocean" cooled affected the formation of the distinct layering ...

Paleogeomagnetic and isotope study reveals the timing of hydrocarbon evolution

In sedimentary basins, the evolution of hydrocarbon including oil/gas generation, migration, and accumulation, as well as reservoir destruction, is often controlled by regional tectonic activities.
