Russia on Wednesday said it was still awaiting a formal answer from Washington on President Vladimir Putin's proposal to jointly stick to the last remaining Russian-U.S. arms control treaty, which ...

The Bulletin of the Atomic Scientists is little more than a decade older than the field of artificial intelligence, whose birth can arguably be traced back to the Dartmouth Summer Research Project on ...

Eighty years after the founding of the Bulletin of the Atomic Scientists, and 55 years after the first Earth Day, humanity faces a growing profusion of existential threats. Most people—including ...

Time on Mars does not match time on Earth, and the difference is no longer a thought experiment. Precision calculations now show that clocks on the red planet tick measurably faster, confirming a ...

Summary: Time doesn’t flow uniformly across the solar system, and new research reveals just how differently it unfolds on Mars compared with Earth. By tracing subtle gravitational and orbital ...

On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab.

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

On Earth, telling time is easy. Our clocks are synchronized using atomic clocks, GPS satellites, and fast communication ...
