Tiny, glowing probes packed with LEDs and sensors are scientists’ newest tool for measuring and manipulating the brain and other living tissues. They’re flexible, they can operate wirelessly, and yes, they’re small enough to fit through the eye of a needle.

For a few minutes on Thursday night, San Francisco’s new Bay Bridge was bathed in radiant white light, spilling down from thousands of LEDs, mounted on a new lighting system unlike any other.

Lamps have been making streets safer for driving since before cars were invented. Eventually, they featured hoods to reduce light pollution, and LEDs to increase efficiency. But when Bleyco, the electrical contractor for the new $7 billion bridge from Oakland to San Francisco, decided they wanted the most advanced system ever made, they reached out to a sports-lighting manufacturer, Musco.

The idea was to use cutting-edge directional lighting to carpet the bridge in solid white light, without glare on drivers’ windows or patches of dark on the road.

“When Bleyco contacted us about the project, the solution was unknown,” said Musco sales manager Adam DeJong. In 2008, when Bleyco first asked Musco to build it, the technology didn’t exist.
