Scientists reported evidence for a new class of gravitational waves, likely created by merging supermassive black holes.
Today's encryption schemes will be vulnerable to future quantum computers, but new algorithms and a quantum internet could help.
The measurement tool could lay out a distance scale for cosmic dawn —and offer clues to the nature of dark matter.
New experiments put phonons — the tiniest bits of sound — into quantum mechanical superpositions and show they are as weird as other quantum entities.
A single particle of light is the spark that begins the process of turning light to chemical energy in photosynthetic bacteria, a new study confirms.
Kinks in the magnetic fields near the surface of the sun appear to be the cause of fast-moving flows in the solar wind.
Big black holes in little galaxies, rogue black holes and other behemoths could offer clues to cosmic evolution.
In a step toward building a nuclear clock, scientists measured light emitted when a special type of thorium nucleus decayed.
Particle-like quantum states called non-abelian anyons remember being swapped and could be useful for protecting information in quantum computers.
