A microquasar belonging to our Milky Way galaxy has set records by generating cosmic rays with energy levels never before ...

For the first time, researchers have seen how light behaves during a mysterious phenomenon called 'imaginary time'.

The inner-shell X-ray lasing process is similar to optical lasing, just at a much shorter wavelength. An initial pulse of X-ray photons excites atoms' inner-shell electrons.

Energy from the sun’s rays can cause skin damage and cancers. Sunscreens can absorb or reflect the dangerous UV light. Here’s ...

Cosmic radiation occasionally contains enormous amounts of energy, but we don’t know why or where this radiation comes from.

Traditional medical tests often require clinical samples to be sent off-site for analysis in a time-intensive and expensive ...

Since their discovery by Wilhelm Roentgen in 1895, X-rays have become a staple of modern medical care, from imaging teeth and ...

Quantum sensors have become important tools in low-energy particle physics. Michael Doser explores opportunities to exploit ...
