Einstein’s theory of relativity just got 500X harder to beat

Researchers say Einstein's ideas hold up in a new kind of test. "This is a brand new way to test general relativity using supermassive black holes."

Meteorites from Mars contain clues about the red planet's geology

Martian meteorites allow scientists here on Earth to decode that planet's geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.

Pairing lasers with microwaves makes mind-bogglingly accurate electronic clocks – a potential boon for GPS, cell phones and radar

Researchers have made some of the most accurate clocks imaginable in recent years, but the trick is harnessing those clocks to electronics. Using lasers to tune microwaves bridges the gap.
