How space storms miscue train signals

In July 1982, train signals in Sweden misfired and erroneously turned red. The culprit, believe it or not, was a space storm that started 150 million kilometers (93 million miles) away.

Closing in on next-generation atom-thick photonic devices

From microscopes and cameras to night vision devices and optical fiber communications, photodetectors have a wide array of applications. Photodetectors capture and convert light into electrical signals but are often limited ...

Scientists boost quantum signals while reducing noise

A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve certain problems too complex ...
