What if we could peer into a brain and see guilt or innocence? Brain scanning technology is trying to break its way into the courtroom, but can we—and should we—determine criminal fate based on high-tech images of the brain?

When no one is looking, a particle has near limitless potential: it can be nearly anywhere. But measure it, and the particle snaps to one position. How do subatomic objects shed their quantum weirdness?

Ellen Stofan is the NASA chief scientist, serving as principal advisor on the agency’s science programs. Prior to her appointment, Stofan was vice president of Proxemy Research and an honorary …

“We can rebuild him. We have the technology,” began the opening sequence of the hugely popular 70’s TV show, “The Six Million Dollar Man.” Forty-five years later, how close are …

The mysteries of dark matter and dark energy may be evidence that we don’t fully understand the force of gravity. But when it comes to a force that has been studied mathematically and probed observationally for hundreds of years, what do we still need to learn?

Can the spooky world of quantum physics explain bird navigation, photosynthesis and even our delicate sense of smell? Clues are mounting that the rules governing the subatomic realm may play an unexpectedly pivotal role in the visible world.
