We Are Electric
Sally Adee

It took just a 9-volt battery and a little brain zapping to turn science writer Sally Adee into a stone-cold sharpshooter.
She had flown out to California to test an experimental DARPA technology that used electric jolts to speed soldiers’ sniper training. When the juice was flowing, Adee could tell. In a desert simulation that pit her against virtual bad guys, she hit every one.
“Getting my neurons slapped around by an electric field instantly sharpened my ability to focus,” Adee writes in her new book, We Are Electric. That brain-stimulating experience ignited her 10-year quest to understand how electricity and biology intertwine. And she’s not just talking neurons.

Bioelectricity, Adee makes the case, is a shockingly underexplored area of science that spans all parts of the body. Its story is one of missed opportunity, scientific threads exposed and abandoned, tantalizing clues and claims, “electroquacks” and unproven medical devices — and frogs. Oh so many frogs.
Adee takes us back to the 18th century lab of Luigi Galvani, an Italian scientist hunting for what gives animals the spark of life. His gruesome experiments on twitching frog legs offered proof that animal bodies generate their own electricity, an idea that was hotly debated at the time. (So many scientists repeated Galvani’s experiments, in fact, that Europe began to run out of frogs.)
But around the same time, Galvani critic Alessandro Volta, another Italian scientist, invented the electric battery. It was the kind of razzle-dazzle, history-shaking device that stole the spotlight from animal electricity, and the fledgling field fizzled. “The idea had been…
