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 ...

Model development is crucial in understanding climate change

Numerical models are a key tool for climate scientists in understanding the past, present and future climate change arising from natural, unforced variability or in response to changes, according to Dr. Qing Bao, Research ...

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 ...

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, ...

Lasers make magnets behave like fluids

For years, researchers have pursued a strange phenomenon: When you hit an ultra-thin magnet with a laser, it suddenly de-magnetizes. Imagine the magnet on your refrigerator falling off.

Building confidence in hydrologic models

Understanding water availability and quality for large-scale surface and groundwater systems requires simulation. Scientists have developed many numerical models to address these simulation needs. How do these models differ ...

Researchers offer new information warfare model

Researchers have collaborated to develop a mathematical model of information warfare in a society under periodic destabilization. The authors of the paper, which was published in Mathematical Models and Computer Simulations, ...

The return of the comet-like exoplanet

Astronomers from the University of Geneva (UNIGE), Switzerland and collaborators used the Hubble Space Telescope to study an exoplanet that had been observed losing its atmosphere, forming an enormous cloud of hydrogen and ...
