Simulations suggest that when a quantum battery shares a quantum state with the device it is powering, the device can gain more charge than was stored in the battery to begin with

Inside a hunk of a material called a semimetal, scientists have uncovered signatures of bizarre particles that sometimes move like they have no mass, but at other times move just like a very massive particle

A surprising reversal of our usual understanding of the second law of thermodynamics shows that it may be possible for heat to move in the “wrong” direction, flowing from a cold area to a warm one

A new supercapacitor design that uses only water, clay and graphene could source material on Mars and be more sustainable and accessible than traditional batteries

Allowing for moves that create quantum superpositions makes a quantum version of a Rubik’s cube incredibly complex, but not impossible to solve

Droplets of fluid have been known to hover above a hot surface, but a new experiment suggests the same can happen to tiny jets of liquid too

With the help of a ruby cube and two laser beams, researchers made one ray of light cast a shadow when illuminated by the other By Karmela Padavic-Callaghan
