A new measurement of the exotic “atom” — consisting of an electron and its antiparticle, a positron — disagrees with theoretical calculations, scientists report in the Aug. 14 Physical Review Letters.

The world's biggest atom-smasher has set a world record by accelerating to energy levels that had never been previously reached, the European Organisation for Nuclear Research (CERN) said Monday.

Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto a higher energy level, a ...

The idea of powering a house with a single atom might seem like science fiction, but recent advancements in nuclear physics and energy research suggest it could be closer to reality than we think.
