Inside a thunderstorm, warm air is forced upward in a strong updraft. As the air rises, ice and water particles collide inside the cloud, creating electrical charges. Those collisions build up ...

In a small lab at Penn State University, lightning may be happening on a scale smaller than a deck of cards. Victor Pasko, a professor of electrical engineering, and his team have shown that under ...

The scientific community long assumed that to understand how lightning works, one needed a massive storm cloud. But a new modeling study shows mini-lightning can be created and studied inside a small ...
