(Phys.org)—Rogue waves in the middle of the ocean often appear out of nowhere and vanish just as quickly. But in their short lifetimes, they can generate walls of water 15 to 30 meters (50 to 100 feet) high, crashing down ...
A team of researchers at Laroche Laboratory, Université Paris Diderot and Université de Lyon has recently collected the first measurements of the resonance frequencies of a stable torus of fluid. The method they used to ...
(PhysOrg.com) -- Using magnetic nanodots in the vortex state, researchers have designed a new kind of non-volatile memory that could offer increased speed and density for next-generation non-volatile random access memories ...
A record-breaking cold wave is sending literal shivers down the spines of millions of Americans. Temperatures across the upper Midwest are forecast to fall an astonishing 50 degrees Fahrenheit (28 degrees Celsius) below normal ...

A small international team of researchers has found that water waves created due to scattering from a spinning vortex can show rotational superradiance—an effect astrophysicists have predicted likely to occur in black holes, ...
Millions of people in northern Europe are still battling snow and ice, wondering why they are being punished with bitter cold when—officially—spring has arrived and Earth is in the grip of global warming.
