The insights of a provocative connection between general relativity and quantum field theory, called the AdS/CFT correspondence, have been extended to rotating black holes that can occur astrophysically.
Quantum field theoretic extensions of Einstein’s theory of gravity tend to suffer from incurable infinities, but a theory called supergravity may actually avoid them—against expectations held for almost 30 years.
A huge, predicted atomic parity violation has now been observed in ytterbium, further aiding tabletop experimental searches for physics beyond the standard model that complement ongoing efforts at high-energy colliders.

Ultrahigh energy photons striking matter can transform into rho mesons through an interaction that involves many nuclei simultaneously, a phenomenon that may affect the detection signatures of high-energy particles from space.
