Researchers have reported a link between chirality — the handedness of molecular and physical structures — and spin, grounded in established symmetry principles rather than new postulates. The finding ties two fundamental concepts in physics and chemistry into a single framework. Interest centres on what the connection means for materials science, quantum systems and our understanding of symmetry in nature.

The work may aid the design of future quantum technologies, though detailed results and the institutions involved were not specified in available reports.

Physicists report detecting Cooper pairs surviving above the superconducting critical temperature within pair density waves, a surprising result since pairs normally break apart once a material loses superconductivity. The observation could reshape understanding of how superconductivity emerges and how high-temperature superconductors work, and it is drawing attention from researchers studying quantum materials.

Physicists report observing a new quantum state of matter in which electrons move at a drastically reduced speed, behaving far differently than in ordinary conductors.
