Vienna University of Technology With neutrons, scientists can now look for dark energy in the lab All the particles we know to exist make up only about five per cent of the mass and energy of the universe. The rest – "Dark Matter" and "Dark Energy" – remains mysterious. A European collaboration led by researchers from the Vienna University of Technology has now carried out extremely sensitive measurements of gravitational effects at very small distances at the Institut Laue-Langevin...

Mainz has the most powerful source of ultracold neutrons, opening up the possibility of conducting a key experiment to determine the life time of the neutron Scientists at Johannes Gutenberg University Mainz (JGU) have built what is currently the strongest source of ultracold neutrons. Ultracold neutrons (UCNs) were first generated here five years ago. They are much slower than thermal neutrons and are characterized by the fact that they can be stored in special containers. This property...
