GREEN BAY, Wis. (WBAY) - As a kid, did you ever shine a bright flashlight at your fingers, making them almost see-through? What did you see? Bones? Arteries?

Some scientists never grow up. There are smartphones and smartwatches on the market that promise to measure blood-oxygen levels by shining a light on your skin -- but Brad Spakowitz tells us a new, highly accurate method has been devised using your phone’s flashlight and camera. He shows you how it works and its possible uses.

Also, the Artemis moon rocket faces a critical test Wednesday.

And an update on DART, a mission to crash a satellite into an asteroid to see if the asteroid will change direction. Tell “Armageddon”'s Bruce Willis and Ben Affleck they can stay home if it works next week!
