Great earthquakes, water under pressure, high risk

The largest earthquakes occur where oceanic plates move beneath continents. Obviously, water trapped in the boundary between both plates has a dominant influence on the earthquake rupture process. Analyzing the great Chile ...

Researchers reveal the tangle under turbulence

Picture the flow of water over a rock. At very low speeds, the water looks like a smooth sheet skimming the rock's surface. As the water rushes faster, the flow turns into turbulent, roiling whitewater that can overturn your ...

Stripes in a flowing liquid crystal suggest a route to 'chiral' fluids

Hold your hands out in front of you, and no matter how you rotate them, it's impossible to superimpose one over the other. Our hands are a perfect example of chirality—a geometric configuration by which an object cannot ...

Scientists gain insight into geothermal-technology-induced seismicity

EPFL scientists have developed a model that sheds light on the seismic risks arising from subsurface fluid injections carried out as part of geothermal energy extraction.

Extended Coulomb failure criteria for the Zipingpu reservoir and Longmenshan slip

The extended Coulomb failure stress (ECFS) criteria and anisotropic porosity and permeability tensor at micro/meso/macro scale under ultra‑high temperature and pressure (UTP) conditions were developed employing the ...

Study reveals the keys to the locomotion of snails

A research study has found evidence that suggests that the key to locomotion in snails stems from the animal's complex muscle movements, and not from its mucus, as had been previously thought. This finding could open the ...

150 years later, Darwin vindicated... by jellyfish: Researchers link tiny sea creatures to large-scale ocean mixing

(PhysOrg.com) -- Creatures large and small may play an important role in the stirring of ocean waters, according to a study released Wednesday that confirms a theory advanced by Charles Darwin.

Going with the flow: Scientists solve 100-year-old engineering problem

(PhysOrg.com) -- As a car accelerates up and down a hill then slows to follow a hairpin turn, the airflow around it cannot keep up and detaches from the vehicle. This aerodynamic separation creates additional drag that slows ...
