A Photonic Crystal in Time

Metamaterial-based device working at terahertz frequencies could be turned into a new type of laser.

Controlled cracking technique prints quantum dots into tiny pixels for sharper displays

Recent technological advances have enabled the development of increasingly sophisticated, sharper displays for electronic devices. Many modern displays use light-emitting diodes, or LEDs, tiny semiconductor-based components that emit light when an electrical current passes through them.

Scientists uncover the aluminium shield that helps a tiny crustacean survive darkness, nearfreezing water and crushing pressure in the Mariana Trench

Nearly seven miles beneath the surface of the Pacific Ocean lies a place so hostile that only a handful of human beings in all of history have ever seen it. Total darkness, near-freezing water, and pressure equivalent to a jet’s weight bearing down on a single postage stamp define this world.

Chemists set electrons free and break a decades-old chemistry barrier

Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that were previously out of reach.
