The Quantum Secret to Superconductivity
In a virtuoso experiment, physicists have revealed details of a “quantum critical point” that underlies high-temperature superconductivity.
Searching the Sky for the Wobbles of Gravity
The physicist Gabriela González is on the cusp of finding the first direct evidence of gravitational waves — soundlike wobbles in space-time produced by black holes and their kin.
Dark Energy Tested on a Tabletop
Is dark energy a cosmic chameleon that can fade into its surroundings? A recent test brings the mysterious anti-gravitational force down to earth.
Fluid Tests Hint at Concrete Quantum Reality
Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised.
Search Escalates for Key to Why Matter Exists
Physicists have completed a new round of searches for the answer to why matter dominates over antimatter. But the radioactive decay that would solve the puzzle is evading them.
In Hunt for Dark Matter, Promises to Keep?
Whispers of the elusive particles are becoming stronger with a series of signals that appear to be zeroing in on a leading contender.
Perpetual Motion Test Could Amend Theory of Time
A radical theory predicting the existence of “time crystals” — perpetual motion objects that break the symmetry of time — is being put to the test.
