Scientists simulate a black hole in a water tank

Certain phenomena that occur in black holes but cannot be directly observed in astronomic investigations can be studied by means of a laboratory simulation. This is possible due to a peculiar analogy between processes that ...

Correcting the eyesight of microscopes

Scientists have discovered a new property of wave propagation that leads to a new way to improve the resolution of virtually all optical technologies, including microscope lenses, telecommunications, laser-based lithography, ...

Catching mantle plumes by their magma tails

Hawaii's volcanos stand as silent sentinels. They guard the secret of how they formed, thousands of miles away from where the edges of tectonic plates clash and generate magma for most volcanos. A 2017 Nature study by Jones ...

Wave beams mix and stir the ocean to create climate

Ocean circulation patterns have a profound effect on global climate. Waves deep within the ocean play an important role in establishing this circulation, arising when tidal currents oscillate over an uneven ocean bottom. ...

Real-time imaging of cell components including DNA

Optical microscopes that use lenses to bounce photons off objects have trouble distinguishing nanometer-scale objects smaller than the imaging beam's wavelength, such as proteins and DNA. An innovative 'hyperlens' designed ...

UA engineers twist physics laws to boost sonic science

For decades, advances in electronics and optics have driven progress in information technology, energy and biomedicine. Now researchers at the University of Arizona are pioneering a new field—phononics, the science of sound—with ...

Physics of 'booming' and 'burping' sand dunes revealed

Avalanching sand from dune faces in Death Valley National Park and the Mojave Desert can trigger loud, rumbling "booming" or short bursts of "burping" sounds—behaving as a perfectly tuned musical instrument.
