Numerical model pinpoints source of precursor to seismic signals

Numerical simulations have pinpointed the source of acoustic signals emitted by stressed faults in laboratory earthquake machines. The work further unpacks the physics driving geologic faults, knowledge that could one day ...

How to capture waste heat energy with improved polymers

By one official estimate, American manufacturing, transportation, residential and commercial consumers use only about 40 percent of the energy they draw on, wasting 60 percent. Very often, this wasted energy escapes as heat, ...

The far-future ocean: Warm yet oxygen-rich

The oceans are losing oxygen. Numerous studies based on direct measurements in recent years have shown this. Since water can dissolve less gas as temperatures rise, these results were not surprising. In addition to global ...

How to bend waves to arrive at the right place

Waves do not always spread uniformly into all directions, but can form a remarkable "branched flow." At TU Wien (Vienna) a method has now been developed to control this phenomenon.

Saturn's moon Mimas, a snowplow in the planet's rings

The Solar System's second largest planet both in mass and size, Saturn is best known for its rings. These are divided by a wide band, the Cassini Division, whose formation was poorly understood until very recently. Now, researchers ...

Supercomputing dynamic earthquake rupture models

Some of the world's most powerful earthquakes involve multiple faults, and scientists are using supercomputers to better predict their behavior. Multi-fault earthquakes can span fault systems of tens to hundreds of kilometers, ...
