What would it take to hide an entire planet? It sounds more like a question posed in an episode of "Star Trek" than in academic discourse, but sometimes the bleeding edge of science blurs with themes found in science fiction.
(Â鶹ÒùÔº)—Ideal invisibility cloaks like those in Harry Potter may be physically impossible, a new study shows. The researchers demonstrate that even the best invisibility cloaks can hide an object from only some observers, ...
Iowa State University engineers have developed a new flexible, stretchable and tunable "meta-skin" that uses rows of small, liquid-metal devices to cloak an object from the sharp eyes of radar.
Since ancient times, people have experimented with light, cherishing shiny metals like gold and cutting gemstones to brighten their sparkles. Today we are far more advanced in how we work with this ubiquitous energy.
A team of quantum physicists at Aalto University led by Dr. Sorin Paraoanu managed to tame a so-called "dark state" created in a superconducting qubit. A superconducting qubit is an artificial atom fabricated on a silicon ...
3-D lattice with glassy carbon struts and braces of less than 200 nm in diameter has higher specific strength than most solids.
(Â鶹ÒùÔº)—Â鶹ÒùÔºicists have found that invisibility cloaks that can achieve perfect invisibility when not in motion will become visible when moving at speeds of around thousands of meters per second. This is because invisibility ...
(Â鶹ÒùÔº)—Over the past few years, scientists have demonstrated the phenomenon of "one-way light," in which a light beam propagates in one direction only. The materials used to achieve this effect can be thought of as ...
For many of us, daily exercise poses little more risk to our overall safety than few minutes of flush or rapid heartbeat. But for the see-through Ancylomenes pedersoni, or Pederson's cleaner shrimp, their physiological response ...
A team of scientists from the Moscow Institute of Â鶹ÒùÔºics and Technology (MIPT) and the Landau Institute for Theoretical Â鶹ÒùÔºics at the Russian Academy of Sciences has proposed a two-dimensional metamaterial composed of silver ...
