Scientists have come up with a new invisibility cloak capable of concealing objects in diffusive atmospheres, not just in permanent light, made possible by the cloaks developed so far, but also in any kind of light. Their work, which establishes the bases to render undetectable, for example, a plane in the fog or a submarine in the sea.
Scientists have developed a theory that gives the possibility to precisely predict the level of noise caused by the amplification of photonic and plasmonic signals in nanoscale optoelectronic circuits.
In a carefully designed polymer, researchers have imprinted a sequence of a single strand of DNA. The resulting negative remained chemically active and was capable of binding the appropriate nucleobases forming a genetic code. The polymer matrix thus functioned exactly like a sequence of real DNA.
