Often viewed as “spooky” or downright bizarre, quantum mechanics is fueling a powerful new era of amazing technology. In this program, today’s top quantum physicists discuss the information shake-up underway—and predict when we can expect a quantum computer of our own.

A new generation of technology is revolutionizing neuroscience, allowing a closer study of the brain than had ever seemed possible. The techniques are hybrids of optics, genetics, and synthetic biology …

Einstein dreamed of a unified theory of nature’s laws. String theory has long promised to deliver it: a mathematically elegant description that some have called a “theory of everything.” Join …

In celebration of the 100th anniversary of Einstein’s general theory of relativity, we examine its essential insights, its lingering questions, the latest work it has sparked, and the allied fields of research that have resulted.

When we try to get rid of a bad habit, whether it involves food or drugs or gambling, it often seems like we’re fighting ourselves inside. The reality’s not far off: Addiction twists the reward pathways of the brain to keep addicts tied to whatever gets them high.

The nature of time is an age-old conundrum for physicists, philosophers, biologists and theologians. The Newtonian picture of time—a kind of cosmic clock that ticks off time in a manner that applies identically to everyone and everything—tightly aligns with our experience. But with special and general relativity, Einstein showed the fallacy inherent in experience.
