The idea that light has momentum is not new, but the exact nature of how light interacts with matter has remained a mystery for close to 150 years. New research from UBC's Okanagan campus, recently published in Nature Communications, ...

Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered "elastic" waves. These waves travel at the surface or through a material without ...

In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye ...
Current understanding is that the chemical composition of the Earth's mantle is relatively homogeneous. But experiments conducted by ETH researchers now show that this view is too simplistic. Their results solve a key problem ...

(Phys.org) —Defining the essential character of the action potential of neurons has proven to be an elusive task. As typically happens, the biggest advances seem to have been made early on. In this case it was Hodgkin and ...
Skyrmions are extremely small with diameters in the nanoscale, and they behave as particles suited for information storage and logic technologies. In 1961, Tony Skyrme formulated a manifestation of the first topological defect ...
A metamaterial invisibility cloak that can adapt to hide different sized objects is demonstrated by in Nature Communications this week. The findings represent a useful advance for more practical applications of metamaterial ...

A team of researchers from the University of Exeter and Piazza Leonardo da Vinci, has shown, theoretically, that corkscrew elastic waves carry well-defined orbital angular momentum. In their paper published in the journal ...
A collaborative of Russian researchers has mathematically modelled diamond-based microstructures for producing compact, high-sensitivity sensors.
