Four Earth orbiting satellites have recently measured streams of isolated electric field pulses traveling along the Earth’s magnetic fields in regions as diverse as the auroral ionosphere, the Earth’s ...

Electron microscopes can allow you see incredibly small things using a beam of electrons rather than a beam of light. They can provide incredibly fine detail, hence why many scientists use them to ...

An animation shows how an infrared laser beam (orange) triggers atomic vibrations in a thin layer of iron selenide, which are then recorded by ultrafast X-ray laser pulses to create an ultrafast movie ...
