When you knock on a melon to see if it's ripe, you are using sound waves to probe the structure of the material inside. Physicists at the University of Chicago were using the same concept to explore how sound waves travel ...
In a paper published in Cell Reports, a team of researchers from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University discovered unique characteristics of a protein called VISTA that protects ...
With apologies to "Spinal Tap," it appears that black can, indeed, get more black.
Two teams of researchers, one in Korea, the other China, have devised two different types of invisibility cloaks for water applications. Both teams have published papers describing their work in the journal Physical Review ...
Metamaterials are artificial materials engineered to have properties not found in naturally occurring materials, and they are best known as materials for invisibility cloaks often featured in sci-fi novels or games. By precisely ...
Whether Harry Potter's invisibility cloak, which perfectly steers light waves around objects to make them invisible, will ever become reality remains to be seen, but perfecting a more crucial cloak is impossible, a new study ...
In the past decade scientists have been experimenting with metamaterials, artificial materials designed with periodic internal structures to give them properties not found in natural materials. Depending on their internal ...
A pair of researchers at Tokyo Institute of Technology (Tokyo Tech) describes a way of making a submicron-sized cylinder disappear without using any specialized coating. Their findings could enable invisibility of natural ...
The first picture of a supermassive black hole at the centre of a galaxy shows how we have, in a sense, observed the invisible.
Sandia National Laboratories has created the first inverse-design software for optical metamaterials—meaning users start by describing the result they want, and the software fills in the steps to get there. The modern design ...
