For the first time, researchers have confirmed the existence of antimatter in the Earth's magnetosphere.

Physicists at the US-based Fermilab have produced a new particle that is a heavier relative of the neutron.

Researchers at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM), together with their colleagues from the Max Planck Institute for Nuclear Physics in Heidelberg and the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, have observed spin quantum-jumps with a single trapped proton for the first time.

Data that hinted at the possible discovery of a new sub-atomic particle has been rejected after cross-checks failed to find support for the initial observation.

Scientists at Johannes Gutenberg University Mainz (JGU) have built what is currently the strongest source of ultracold neutrons.
