Semiconductor detectors that directly measure the electrical signals produced by X-rays have hugely improved the resolution and contrast of computed tomography scanners. In the 1970s computed ...

Physicists at the UK’s Central Laser Facility have recorded the first observation of quantum radiation reaction, detecting how electrons lose energy in ways that classical physics cannot explain when ...

Amidst rapid performance improvements and industrial scaling of perovskite–silicon solar cells, researchers wait with bated breath for the outcome of reliable long-term testing. The latest updates, ...
