No one can match these electrons when it comes to relaxing. Within a few hundred attoseconds – billionths of a billionth of a second – of being hit by an X-ray pulse, they are already back where they were, sitting calmly in a low-energy state. Image: Attoelectronics Group, MPQ

The ultimate high-speed flashbulb just measured how quickly electrons inside atoms respond to light. The work could speed the development of light-based electronics. At 380 attoseconds long – 380 x 10^-18 seconds – the flashes are the shortest pulses of visible light ever created in the lab. Image: Christian Hackenberger/Attoelectronics MPQ
