Transistors are fundamental to microchips and modern electronics. Invented by Bardeen and Brattain in 1947, their development is one of the 20th century's key scientific milestones. Transistors work ...

A new quantum sensing approach could dramatically improve how scientists measure low-frequency electric fields, a task that has long been limited by bulky setups and blurry resolution. Instead of ...

An electric charge (like a proton) creates an electric field in the region around it. This field points away from positive charges and decreases in strength as it gets farther away from the charge.

In the home, the lab and the factory, electric fields control technologies such as Kindle displays, medical diagnostic tests and devices that purify cancer drugs. In an electric field, anything with ...
