The Arrhenius equation, which has accurately described rates of chemical reactions for more than a century, may have to be tweaked for the quantum realm

The direction of cause and effect was brought into question for quantum objects more than a decade ago, but new calculations may offer a way to restore it

A new design for a nuclear battery that generates electricity from the radioactive decay of americium is unprecedentedly efficient

Particles of light can spend "negative time" passing through a cloud of extremely cold atoms – without breaking the laws of physics

Nearly imperceptible quantum flickers used to limit how precisely we could detect the way space-time ripples, but squeezing the laser light used in

Though it was first predicted in the 1930s, chemists have just now managed to create a covalent bond that only uses one electron

A computer simulation suggests that some collisions between exotic, hypothetical stars would make space-time ripple with detectable waves
