Laser light makes a comeback (literally)

Straight-line constant-speed propagation in free space is a basic characteristic of light. In a recent study published in Communications Physics, researchers from Osaka University discovered the phenomenon of reciprocating ...

Progress in the low-cost electrochemical synthesis of ammonia

Ammonia (NH3) is mass-produced for use in the agricultural, pharmaceutical, and sustainable energy sectors. However, its conventional synthesis methods are environmentally unfriendly, so we need alternatives! Recently, Scientists ...

Magnetism meets topology on a superconductor's surface

Electrons in a solid occupy distinct energy bands separated by gaps. Energy band gaps are an electronic "no man's land," an energy range where no electrons are allowed. Now, scientists studying a compound containing iron, ...
