'Ghostly' neutrinos provide new path to study protons

Neutrinos are one of the most abundant particles in our universe, but they are notoriously difficult to detect and study: they don't have an electrical charge and have nearly no mass. They are often referred to as "ghost ...

An illuminated water droplet creates an 'optical atom'

Shining light on a water droplet creates effects analogous to what happens in an atom. This can help us understand how atoms work, write researchers from the University of Gothenburg in a new journal article published in ...

Scientists couple terahertz radiation with spin waves

An international research team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) has developed a new method for the efficient coupling of terahertz waves with much shorter wavelengths, so-called spin waves. As the experts ...
