When laser flashes hit matter, electrons are knocked off their orbits around the atomic nuclei. This can generate extremely hot plasmas composed of charged particles—ions and electrons. Researchers at ...

In the experiment, the XFEL photon energy was carefully tuned to match a specific electronic transition in highly charged copper ions created by a high-power laser (red). Under these conditions, the X ...

A dramatic blast erupts when molten copper reacts unexpectedly, leaving onlookers stunned that no one was seriously hurt. Is Trump already a lame duck — or more dangerous to Canada than ever? Mother ...
