Mechanical unloading during spaceflight disrupts skeletal homeostasis through coordinated alterations in bone remodeling, vascular architecture, and local tissue oxygenation. Although low-intensity ...

Physicists have directly observed a long-predicted quantum effect of gravity, putting one of Einstein’s foundational ideas to a striking new test. Using ultracold atoms, researchers split an atom’s ...

Quantum mechanics and Einstein's general relativity explain how the Universe works at the tiniest and largest scales, respectively. Quantum mechanics has revealed the probabilistic nature of ...

An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result ...
