(Phys.org) —The ability to guide, bend and focus light at the nanoscale is a highly sought-after goal in the field of nano-optics. Precise and efficient light control has direct applications in solar cells, holography, ...
(Phys.org) —John Howell, a Professor of Physics at the University of Rochester, and his teenage son, have uploaded a paper to the preprint server arXiv in which they suggest that some common magicians' tricks could be used ...
(Phys.org) —The lightweight skeletons of organisms such as sea sponges display a strength that far exceeds that of manmade products constructed from similar materials. Scientists have long suspected that the difference ...

(Phys.org)—In 2011, scientists from the Institute Langevin in Paris built an array of 49 empty coke cans that resonate when exposed to an acoustic wave, causing the cans to produce sound similar to the way blowing across ...
The idea of being able to become invisible, especially by simply covering up a person or an object with a special cloak, has a perennial appeal in science-fiction and fantasy literature. In recent years, researchers have ...

Mechanical metamaterials are sophisticated artificial structures with mechanical properties that are driven by their structure, rather than their composition. While these structures have proved to be very promising for the ...
Boston University researchers have developed a new, "intelligent" metamaterial—which costs less than ten bucks to build—that could revolutionize magnetic resonance imaging (MRI), making the entire MRI process faster, ...
